    PROCEDURE AND EQUIPMENT FOR OBTAINING PROTEIN P.R.D. FROM THE BLOOD OF SUPPLY ANIMALS
    5
    Procedure and equipment for obtaining the P.H.D. from the blood of supply animals.
    OBJECT OF THE INVENTION
    10 15 The present specification defines a procedure and the equipment required to obtain the Hydrolyzed and Discolored Protein of Blood P .H.D. from the blood of food animals. For this, an integral industrial treatment of said blood is carried out from the point of collection and storage until obtaining said protein with optimum levels of quality by means of a series of stages that require an increased network number of elements and equipment which make this procedure increase production compared to existing processes at the same time and allows, in turn, the production costs to be much lower.
    twenty This invention aims to be applied within the biological element treatment industry and specifically in the industrial sector of equipment and treatment of blood from slaughter centers for supply animals for later use.
    BACKGROUND
    2S It is known in the industrial sector related to the use of blood from animals the problem existing in the different steps of its treatment. For example, the problem of achieving stability, sterility, and preservation of blood at the point of collection is raised; in the treatment of sterility it should be noted that the blood is susceptible to being contaminated with
    a certain speed, so that stabilizing products are currently needed to protect the blood for a while without stopping the blood against contaminating elements, mainly during transport and storage; or the inconveniences related to the discoloration, since the strong and persistent pigmentation of the blood makes the final product difficult to use as an additive and therefore makes its commercialization difficult. In this sense, the present invention defines an industrial process that improves conventional treatment systems consisting of a system of continuous collection of blood in the slaughterhouse, and the use of a hydrolyzing reactor and a settling system, all in ambient temperature conditions without the use of cold or heat.
    In the face of these conventional systems, other methodologies that improve said treatment are known, as defined in registry ES8308478, which discloses a method of treating blood and other liquid products in which the blood is treated with anticoagulant that retards coagulation, a compound of sulfur and oxygen, and a carbohydrate; or as defined in register ES2154182 which discloses a procedure for the recovery and purification of blood from industrial slaughterhouses, especially globin, for which physical-chemical processes of extraction, precipitation and separation, which mainly highlights the addition of the aqueous solution of hemoglobin on acetone in such a way that precipitation of globin occurs. It should be noted that the present invention differs from this type of treatments in that it incorporates a differentiated physical-chemical treatment and in that it incorporates different stages of treatment in the collection and reception, separation, filtration, pasteurization, drying and final grinding for obtaining PHD protein under optimal conditions for later use.
    It also highlights the ES2289937 record that differs from the previously defined procedures and that incorporates blood treatment stages from collection to final drying, but that is based on the separation of blood in both hemoglobin and plasma, and after the separation of blood requires at least one reactor for plasma, and another reactor for the treatment of hemoglobin, that is, a minimum of two reactors, and also is based on a
    differential treatment until obtaining the protein P .H.D., being
    in all cases open reactors. The present invention differs from said
    methodology that does not require blood separation, does not require
    different open reactors; it needs a single closed main reactor
    S and airtight. and therefore the rest of the pac;, the procedures differ from the
    methodology defined in that previous record, such as in the processes of
    filtering, hydrolyzing, bleaching and dehydration; and the present invention
    It incorporates automation in all steps of the procedure. It also fits
    It should be noted that the ES2289937 registry methodology has the problem that
    10 Due to the high amount of reactor equipment makes the cost required
    to make a lot is very high since there are many hours needed, in
    concrete, to complete a batch from loading until it ends,
    a total of about 30 hours must pass, an excessive amount of time remaining
    cost effectiveness. The present invention reduces the number of equipment and reactors
    fifteen necessary, thereby reducing the investment cost, as well as reducing the
    time required to obtain a batch of product, for which it is required
    less than half the time of the previous record.
    That is why it is considered that the present invention, which is then
    describes in detail, constitutes an innovative solution that differs
    twenty of the equipment and steps of any type of methodology of treatment of sa ngre de
    animals to date known and presents a solution with which the
    P.H.D. With optimal results for later use, there is a
    Increased production considerably by reducing process times,
    Production costs are much lower, economic investment is reduced
    25 necessary in machinery and the corresponding amortizations, the
    contamination risks when passing through a closed and hermetic circuit; the
    environmental water pollution at the slaughterhouse level by giving it a
    use to the blood that now does not have; you get a raw material of
    high nutritional power and high digestibility for both people and people
    30 animals; and the water consumption for the process is reduced, which is a sensitive
    improvement from an environmental point of view.
    DESCRIPTION OF THE INVENTION
    The present invention defines a process for obtaining the P.H.D. from the blood of supply animals, which is an automated procedure and is composed of the stages defined below.
    5 10 Prior to the definition of the procedure, it is stated that the present invention defines stages that require special equipment that can be located in any location. That is, these equipment for the development of the procedure can be located in the same industrial plant or slaughterhouse, or they can be located in a centralized way at a point or location that requires the transport of blood by tank trucks or remote pumping by conductions In any case, the blood of the animals to be treated needs to be stabilized with conventional reagents.
    1S 20 Additionally, it should be noted that the procedure is automated, for which everything is controlled by a program that manages the production plant, and that it has a set of pre-set parameters for the correct operation of the procedure. In this regard, it must be taken into account that the program regulates the entry or addition into the reactor of the amount of stabilized blood from the slaughterhouse; water, the amount of which is proportional to the entry of blood; dilute hydrochloric acid; sodium hydroxide; and hydrogen peroxide or hydrogen peroxide; just as there are detectors in the reactor for free oxygen, sulphite and pH content. At this point it is emphasized again that the reactor is closed and hennetic, which is new in any type of blood treatment.
    Once the blood is stabilized and ready to be treated, the rest of the stages that are required for the collection or intake of the P.H.D. They are as follows:
    2S Storage in an industrial warehouse OR slaughterhouse of animals.initial ofthebloodobtainedintheplant
    30 -A fixed amount of stabilized blood is loaded into the reactor from the initial reservoir. This reactor has the peculiarity of being closed and being hennetic. The reactor is loaded from the initial tank by a connection pipe with a peristaltic pump.
    The entry of blood into the reactor by the action of the peristaltic pump is slow, so that the liquid slides on the vertical walls to prevent foaming or that the pump delivers the blood in the lower part of the ferrule together with non return valve.
    After the incorporation of the amount of stabilized blood with the reagent from the slaughterhouse, the same amount of water is added to the reactor, using the same system as for the blood, that is, it slides through the vertical walls of the reactor to avoid foaming O from the bottom of the reactor.
    After the incorporation of the same amount of water and blood into the reactor, the stirring blades of the reactor are activated and stirring of the mixture begins at low power and slow speed, 15 Hz maximum, to achieve a uniformity of the liquid without foaming At this point it is emphasized that the important thing about the mixture of blood and water is that foams are not formed, being really indifferent that water is introduced before blood, or vice versa. The important thing is that it is not necessary to previously separate the blood into hemoglobin and plasma, but in the reactor itself the water dilutes the hemoglobin membrane and the protoplasm is released.
    Without stopping the movement of the stirring blades, a dilute hydrochloric acid addition pump adds said acid until it reaches an acidic pH point at which the entire mass coagulates, at which point the addition of hydrochloric acid is automatically stopped. But the agitation continues.
    . The stirring blades continue to work and, then, a sodium hydroxide addition pump slowly begins to incorporate this alkali until a less acidic pH is obtained that corresponds to the moment when the coagulated mass loses its high viscosity to enter a liquid state.
    • Once this pH level is reached, the movement of the stirring blades is stopped for a short period to make sure that said pH value remains stable and does not have alterations that destabilize the hydrogenation concentration. The pH measurement is performed using a pH meter that reaches the bottom, which is where the mixture is located.
    - Proven mass stability, a hydrogen peroxide or hydrogen peroxide application pump, adds this component to the top of the reactor mass so that it begins with its bleaching work. This addition is carried out with the stirring blades stopped.
    - After a long time counted from the first addition of hydrogen peroxide, the same amount of hydrogen peroxide is incorporated again with the same system and methodology. In this way, the standby installation is maintained and in which only the oxidative action of oxygen on the blood hemoglobin and the variation of the pH of the reactor content can be observed, all monitored by the reactor detectors.
    - After a few hours after oxidation begins, and in view of the data indicated in the detectors, a series of calculations are carried out to carry out the precise modifications to achieve maximum effectiveness in the discoloration and for this purpose the pH is modified with the addition of hydrochloric acid and / or hydrogen peroxide, to create the optimal working conditions.
    - Once time passes, the pH is neutralized. To achieve neutralization, the unit adds these components and starts and stops the stirring blades only to stabilize and neutralize the mixture as many times as necessary, until the time comes for the pH to stabilize at the point where that has been left after the last neutralization. In turn, the mixture is neutralized little by little because every time the pH value is raised, the work of the oxygen is put into operation, until it reaches a pH value of around 7.
    - Next, a colloid mill is put into operation, whose function is to make the colloid smaller so that the oxygen works harder and the neutralization process is secured and so that lumps are not produced. The process of driving the colloidal mill is such that the discharge port of the reactor is opened and a mono pump that extracts product from the reactor starts, enters it at the entrance of the colloid mill, the colloid mill acts on the mixture. and this one conducts it again by means of conduits to the interior of the reactor generating a closed circuit.
    After a few minutes of recirculating the mixture, the system calculates the pH values in the reactor and adds sodium hydroxide to correct the acidity that the product may have.
    When the content of the reactor is considered to be a yellowish-colored mass of micronized appearance, a bypass valve is opened so that the product is led to a lung reservoir that has stirring blades in operation. Similarly, when the reactor is empty, the product remains are carried away, which are recovered together with those of the pipes and the colloid mill, and are led to the lung tank so that the entire mixture is in said lung deposit
    - After the emptying, the reactor agitator is stopped, while the pump and the colloid mill remain in operation. With a network water hose, the reactor is washed internally, so that in a single operation, all hydrolyzed particles are carried away to the lung tank. Then the reactor discharge mouth is closed, so that the interior of the pressure reactor is subsequently washed to remove any remaining solid matter that may have adhered to the walls. The washing waters, together with others resulting from the process, are taken to a storage tank to be subjected to a water recovery action. Once the cleaning operation is finished, a pneumatic activator closes the discharge mouth of the reactor, which ends the hydrolysis and discoloration phase, and the previous steps can be started again to load another new reactor with new raw material or stabilized blood from the industrial slaughterhouse of supply animals.
    - Once the blood has been subjected to the hydrolysis and decolorization phase, the resulting product in the form of a suspension of solid and liquid, which is in the lung tank under agitation. It is still treated as the possible bisulfite that remains in the blood must still be oxidized.
    - When the product is stabilized, the lung reservoir transmits a signal and the following steps are started:
    • First, a low-speed centrifugal filter pump is loaded so that the solid is retained while the water is expelled. The maximum level of solids retained in the basket of the centrifugal filter pump is decided by a thickness gauge and when the maximum amount of cake has been achieved, said pump stops injecting hydrolyzate, and then, water is injected for washing network . The introduction of mains water is continued to extract and wash the contents until the salt detector indicates that these salts have been eliminated. At that time the inlet of the wash water is stopped and the filter centrifugal pump is automatically accelerated until it stops expelling water;
    • then the revolutions of the centrifugal filter pump descend to the discharge level and. then, a hydraulic blade descends inside the basket to release the product or compact cake. which falls into a hopper that is located at the bottom of the centrifugal filter pump; Y
    • finally, an extraction auger collects the drained cake and moves it to a hopper designed to feed the dryer.
    - The dryer receives the wet cake, which is dehydrated in a regular and continuous way.
    - Started this drying process and after checking that the humidity of the final product is adequate, 6% -7% maximum humidity, and that the temperature does not exceed 402C, the product is sent to a feed hopper of the micronized mill where it is subjected to grinding and cooling.
    - The product or the P.H.D. Dehydrated and ground is collected at the exit of a pneumatic cyclone and there it is packaged under conditions that guarantee its perfect preservation in suitable containers.
    An analysis of the final product obtained shows us values of:
    Crude protein (Nx6.25) 96.29%
    Digestible protein 95.85%
    Protein digestibility 99.55%
    Ethereal extract 1.50%
    Ashes 2.00%
    Total iron 2,000 p.p.m.
    This is a slightly yellowish product and with a semolina-like appearance of loose texture, just as the aminogram achieved is excellent in general, tTíptophan not being found as a hydrolyzed product, and obtaining a weight
    5 molecular protein P .H.S. of about 366.50 Dalton.
    The special and innovative equipment required for the development of the methodology previously described, and that at certain points has already been advanced, is:
    1.-A special reactor.
    It is a closed and hermetic reactor, for the control of oxygen and the rest of 10 variables, preferably made of steel. The capacity is at least four times the volume of blood to be treated.
    Said reactor has an entry hole with closure, an anchor-type stirrer at the bottom with extended ends upwards and inclined blades perpendicular to the axis and distributed in its height. The reduction motor has a frequency inverter for power regulation, preferably 30
    r.p.m. and about 5 CVs per 1,000 I of blood. The shaft has a diameter preferably between 70mm and 100mm.
    On the other hand, in the top cover, since the reactor is closed, it has a PH or pH meter, a nozzle for acid entry, a nozzle
    20 for the entrance of alkali and a nozzle for the incorporation of hydrogen peroxide.
    In the lower part there is an inlet for the blood load with a non-return valve, a sight glass in the ferrule to see the state of the product in reaction, an inlet in the upper part of the ferrule with a curve and a tube of
    5 discharge of the colloidal mill inside the reaction mass. It also has a lower discharge port, a mono-type pump, and after this pump a bypass so that the product goes to the colloid mill or to the lung tank that receives, maintains or feeds the centrifugal filter pump.
    2. -An adjustable colloid mill
    10 As mentioned in the development of the methodology, the neutralization phase of the mixture undoes the blood mass and, the final result, is a manipulable product, of a blackish color with coarse particles. This product and its particle size, once the critical precipitation pH is regulated, the hydrogen peroxide is added for discoloration. and you can see how there are many fine bleached particles while the thickest ones stand out for a dark color that is expensive to lose.
    fifteen In order to solve this problem, a colloid mill with metal mills located at a controlled separation is used, which receives the product extracted from the pressure reactor. As a consequence of the friction between the strawberries, this mill reduces the particles to a particle size of less than 200 ~.
    twenty In the closed circuit generated from reactor to mill and to reactor again, after a short time, the whole genus is homogenized to a minimum particle size that hydrogen peroxide oxidizes and discolors completely with utmost ease.
    The final product is yellowish in powder appearance called as Hydrogenated Protein Bleached P.H.D. impalpable,Yis
    3.-A lung deposit.
    2S Another equipment that facilitates the acceleration of the manufacturing process is the installation of a lung reservoir that, provided with low speed stirring blades, which allows to maintain a perfect suspension of the hydrolyzed and discolored productJ as well as possible pH corrections. This tank has a mono type pump with a frequency inverter, which regulates the ideal feed flow to the centrifugal filter pump.
    S In this way, while the filtering and dehydrating operation of the mixture is being carried out, the production of a new batch in the hydrolysis and oxidation reactor can be started having been empty and clean. With this it is possible to obtain a greater production and a lower cost per kg of commercial final product obtained is achieved.
    4.-Computer control of the process.
    All equipment is controlled and monitored by an infonnatic control, whose main control is centered on the reactor.
    10 A series of control equipment is available that assess the data that is produced, and transmit it at 4120 mV to the computer center that controls the manufacturing process.
    Different spill cells were digested, which are used to control the amount of ingredients that are introduced into the reactor to begin the transformation process.
    lS It also has a pH measuring electrode that is submerged in the liquid mass of the reactor, and sends the data obtained from existing pH and temperature to the transmitter of the equipment that displays them on a control screen.
    twenty There is also an oxygen analyzer, which is another electrode that continuously measures the amount of free oxygen that is found in the liquid mass and the measured data, as in the case of the pH meter, sends them to the transmitter that It shows them on the control screen.
    A sulphite detector is available, which is continually indicating how their content decreases as the reaction hours pass.
    2S Additionally, there is a control of the water expelled by the centrifugal filter pump, which consists of a probe that transmits values in micro Siemens of the salt content of the water resulting from the washing phase, so that the washing of the cake is with the water pure.
    In the lung tank there are some load cells and a meter
    additional pH.
    Finally there is a computer program or software, which
    introduced into the hard drive of the computer that controls the production plant, and
    S which has a series of parameters that can be varied by the person
    authorized to access them as they are the amount of blood to load in a
    reactor. the amount of water to be added proportionally to the incoming blood or
    the amount of hydrogen peroxide to be added
    Finally, and from a point of view of the environment, it should be noted
    10 water consumption used during the procedure. Specifically1 you can say
    that network water is used that is both mixed with the stabilized blood itself
    from the slaughterhouse as with the different reagents previously described in
    The different stages of the procedure. Initially water is included in the reactor,
    hydrolysis occurs, subsequently discoloration, the colloidal phase is reached
    lS of recirculation and pH stabilization, for subsequent transfer and washing and
    filtered out. At this time there is dehydration, micronized and
    packaging, while on the other hand wastewater is produced after filtering and
    washed. said wastewater being passed through a coal column
    active and an osmosis plant, producing brine on the one hand, and the water is
    twenty taken to an evaporator with which evaporated water is produced but also
    Get reusable water again throughout the process. As an example, of a
    slaughterhouse that collects about 5,000 IIday of blood requires 5,000 I of water for
    reaction; about 250 I of water to dilute acids; 250 l of gua to dilute alkalis; 250
    I of water to dilute the hydrogen peroxide; and about 7,000 l of water for washing
    2S P .H.D; being a total of about 12,750 1. To them we must add about 4,000 I of water
    contributed by blood and about 950 1 of water to evaporate in drying, which makes a
    Total water that reaches the treatment plant of 16,750 1. The salt content in these
    16,750 1 of water to be treated has about 190 kg of sodium chloride and 90 kg of sulfate
    sodium, that is, a total of 280 kg sodium salts. These 16,750 1 of water to
    30 treat treated in a reverse osmosis plant produce water until the
    rejected brines have a concentration of 35 grsll, which is equivalent to
    recover daily as pure, osmotized water, without salts or other waste, some
    8,750 l to incorporate into the head of the plant. The rest, 8,000 l containing a concentration of 35 grs / l can be dehydrated and recover the water if necessary and 280 kg of sodium salts are obtained which, dehydrated, can be compressed into blocks to be made available in extensive ruminant farms . After this
    5 analysis, it can be seen that this procedure is very favorable from an environmental point of view.
    To complete the description that is being made and in order to help a better understanding of the characteristics of the invention, an set of drawings is attached as an integral part of it, where it is illustrative and not
    10 limiting the following has been represented:
    Figure 1 is a representation of the different teams that allow obtaining the final product.
    Figure 2 is a representation of the water cycle with the different phases and equipment of the procedure.
    15 Description of the drawings
    In Figure 1 the representation of the different equipment with which it is allowed to develop the different steps, stages and phases of the process object of the invention can be observed. Specifically, and following the stages of the description, it can be observed that:
    20 -The stabilized blood (S) obtained in the industrial plant or slaughterhouse of animals is stored in the initial tank (1).
    - The amount of stabilized blood (S) from the initial reservoir (1) is charged into the reactor (3). The blood load (S) is carried out by means of a connecting pipe (21) with a peristaltic pump (2), with an inlet valve (22) in the
    25 reactor inlet (3). The entry of blood (S) into the reactor by the action of the peristaltic pump (2) is in slow mode.
    After the incorporation of the amount of blood (S) into the reactor (3), the same amount of water (A) is added to the reactor. For this, the same system is used as for blood, that is, from the initial deposit (1) And by
    By means of the peristaltic pump (2) and the connecting pipe (21), water (A) is introduced into the reactor (3).
    After the incorporation of the same amount of water (A) and blood (S) into the reactor (3), the stirring blades (31) of the reactor are activated and stirring of the mixture begins at low power and slow speed, to achieve a uniformity of the liquid without the formation of lumps.
    - Without stopping the movement of the stirring blades (31), the diluted hydrochloric acid addition pump (4) adds said acid in the reactor (3) until it reaches the acidic pH point to coagulate the entire mass, whose value is in the environment of 1.5 to 3 as strong acid.
    - The stirring blades (31) continue to work and, then, the sodium hydroxide addition pump (5) slowly begins to incorporate this alkali into the reactor (3) until the pH level rises, up to a value in the around 4.5 to 5.5, approaching neutrality.
    - Once the previous pH value is reached, the movement of the stirring blades (31) stops for a short period to verify that the pH remains stable. The pH measurement is carried out by means of a pH meter (32) that reaches the bottom of the reactor.
    - Once the dough stability time has been verified, the hydrogen peroxide or hydrogen peroxide application pump (6) adds this component to the reactor (3) so that the bleaching work begins, with the stirring blades (31) stopped .
    - After a long time counted from the first addition of hydrogen peroxide, the same amount of hydrogen peroxide (6) is incorporated back into the reactor (3) with the same system and methodology. In this way the installation is kept on hold.
    - After a few hours after oxidation begins, and in view of the data indicated in the reactor detectors (3), a series of calculations are carried out to carry out the precise modifications to achieve maximum effectiveness in fading and for this you must change the pH with the addition of hydrochloric acid (4) and / or hydrogen peroxide (6), to create the optimal working conditions.
    - Once time passes and the pH is corrected and neutralized, the equipment adds these components and starts and stops the stirring blades (31) only to stabilize and neutralize the mixture as many times as necessary, so that the mixture is neutralized little by little until it reaches a pH value of the environment of
    7.
    - Then, the colloidal mill (7) is put into operation. The process of driving the colloidal mill (7) is such that the discharge port (33) of the reactor is opened and a mono pump (34) that extracts product from the reactor starts, enters it into the inlet mouth (72) of the mill colloidal, the colloid mill acts on the mixture, and this one conducts it again by means of conduits (71) to the interior of the reactor (3) generating a closed circuit.
    After a few minutes of recirculating the mixture, the pH values in the reactor are calculated with the meter (32) and the compound necessary to correct the acidity that the product may have is added.
    - When the content of the reactor (3) is a yellowish-colored mass of micronized appearance, which is observed with a sight glass (35), the bypass valve is opened
    (73) so that the product is led to the lung reservoir (8) that the agitator (82) has in operation. Similarly, when the reactor (3) is empty, the product remains are carried away, which are recovered together with those of the pipes (7 1) and the colloid mill (7), and are driven and introduced by their inlet mouth (81) in said lung reservoir (8).
    - After the emptying, the agitation blades (31) of the reactor, the mono pump (34), the colloid mill (7) are stopped and the discharge mouth (33) of the reactor is closed, so that later it is washed with water network to drag solid matter remains that may have been attached to the walls. Again, the discharge port (33) of the reactor is opened and the colloidal mill (7) and the mono pump (34) are put into operation. These first wash waters drag all solid remains of P.H, D. that exist in the reactor, mono pump, colloid mill and conduits to the lung tank, Once this operation is finished, you can proceed to the deep cleaning of the equipment whose washing water is channeled to a treatment plant. Once the cleaning is finished, the previous steps can be started again to load another new reactor with new raw material or stabilized blood from the slaughterhouse of supply animals.
    - Once the blood (S) has been subjected to the hydrolysis and discoloration phase, the resulting product is completely in the lung reservoir (8), stirring until stabilized,
    - When the product is stabilized, the lung reservoir (8) transmits a signal and the following equipment is started: the centrifugal filter pump (9), an endless cake extraction and transport in an auger (93) and a mono pump
    (83) that feeds the centrifuge through the mouth (9 1). The centrifugal filter pump (9) is loaded at low speed so that the solid is retained while the reaction water is expelled; the introduction of mains water is continued to extract and wash the salt content; when the level of salts detected at the outlet of the wash water is low, the inlet of the wash water is stopped and the machine automatically accelerates until it stops expelling water; then the revolutions of the centrifugal filter pump descend to discharge level and. then, a hydraulic blade descends inside that scratches to release the product or compact cake that falls into an internal hopper
    (92) which is located at the bottom of the centrifugal filter pump (9); and finally, the extraction auger (93) collects the drained cake and transfers it to a hopper (10) designed to feed the dryer (11) that continuously generates the fine product.
    - The dryer (11) receives the wet cake that is dehydrated in a regular and continuous manner, where once the product is dehydrated, ground and cooled it is packaged under conditions that guarantee its perfect preservation in suitable containers.
    On the other hand, in Figure 2 you can see the representation of the water cycle
    with the different phases and equipment of the procedure, which is important
    from the environmental point of view. Specifically it can be said that it is used
    mains water that is both mixed with the stabilized blood itself from the
    s slaughterhouse as with the different reagents previously described in the different
    stages of the procedure Initially, both water (A) is included in the reactor (3)
    as blood (S), producing a mixture (1) without foaming,
    they add hydrochloric acid (4), sodium hydroxide (5) and hydrogen peroxide (6), from
    so that hydrolysis (H) occurs, subsequently discoloration (IlI), is
    10 reaches the colloidal phase of recirculation (IV) with the mill (7) and stabilization
    pH (V), for subsequent transfer (VI) to the lung reservoir (8), washed and filtered
    (VII) in the centrifugal filter pump (9). At this time it is produced on the one hand
    dehydration (VIII),micronized(IX)Ypacking(X)inthe hopper (10)Y
    dryer (11), while on the other hand wastewater (XI) is produced after
    fifteen filtering and washing (VI), said wastewater being pasttothrougha
    active carbon column (XII) and an osmosis plant (XIII), producing
    brine (XIV) on the one hand, water taken to an evaporator (XV) with which
    It produces evaporated water itself and reusable water is also obtained (XVI)
    Again in the whole process.

    (1) by means of a peristaltic pump (2) and a connecting pipe (21);
    ii) stirring blades (3 1) located in the reactor (3) are activated and stirring of the mixture begins to achieve uniformity of the liquid without foaming;
    Ii) with the stirring blades (3 1) of the reactor (3) in motion, a dilute c1hydrochloric acid addition pump (4) adds said compound into the reactor (3), until it reaches an acidic pH point in the 1.5 to 3 environment;
    iv) following the blades (31) of the reactor (3) in operation, a sodium hydroxide addition pump (5) begins to slowly incorporate this alkali into the reactor (3);
    v) once a pH value in the environment of 4.5 to 5.5 has been reached, the movement of the stirring blades (3 1) is stopped;
    vi) with the stirring blades stopped (31), a hydrogen peroxide application pump (6) adds this component to the reactor (3), repeating this action again;
    vii) after a few hours, the conditions of the mixture are checked and hydrochloric acid (4) and / or hydrogen peroxide (6) is incorporated, with stirring blades (31) being activated or stopped as necessary, until the mixture is corrects and neutralizes to a pH value of 7;
    viii) a colloid mill (7) is put into operation, for this a discharge port (33) of the reactor is opened and a mono pump (34) is started that
    withdraws product from the reactor (3) by passing the product to said colloid mill (7), which after treating and reducing the size of the colloid, returns the product back to the inside of the reactor (3) by means of conduits (71) generating a closed circuit;
    S X)After a few minutes of recirculating the mixture, the pH values in the reactor (3) are calculated and any of the above compounds necessary to correct the acidity of the mixture is added;
    10 x)when the reactor mixture (3) is neutralized and is a yellowish mass, a bypass valve (73) of the closed circuit is opened and the product is led to a lung reservoir (8) that has a stirrer in operation ( 82), where the mixture stabilizes;
    fifteen xi)When the mixture in the lung tank (8) is fully stabilized, a signal is transmitted that starts a mono pump (83) that introduces the product through an inlet (9 1) into a centrifugal filter pump (9) continues , where the product is filtered and washed;
    xii) an auger (93) for extracting the centrifugal filter pump (9) brings the drained product cake to a vat (10) designed to feed a dryer (11); and finally,
    twenty xiii) in the dryer (11) the product is dehydrated in a continuous regular manner, and the milled and finally cooled product is packaged.Y
