    [0001] The present invention relates to installations and methods for defrosting or de-tempering food products. Thawing is the transformation of a frozen food at a negative temperature, as low as it is, into a defrosted food, that is to say having exceeded the melting temperature of the water constituting it. Tempering involves heating a frozen product from its negative storage temperature, no matter how low, to a temperature below. that of the melting temperature of the water constituting it. U.S. Patent 4,898,741 discloses a method and a thawing facility in which water is sprayed into a defrosting cell. A fan can create an air flow at a speed not exceeding 5ms-1. Defrosting or tempering a product requires meeting two contradictory requirements that are on the one hand the interest of defrosting or rapid tempering and on the other hand the maintenance of a sufficiently low temperature on the surface to avoid damaging the product. The advantage of rapid thawing is to improve the sanitary quality of the thawed food products, so as to prevent the defrosting time from exceeding the latency time of the pathogenic bacteria and the weathering flora. Exusal losses are also reduced.
    [0002] Another advantage of a short-time defrosting is to be able to quickly feed the production lines and work in a just-in-time flow. The interest of maintaining the surface temperature at a controlled value is to best preserve the appearance after thawing of certain sensitive food products, especially certain fish, such as tuna, mackerel or sardines, in particular by avoiding a discoloration of their skin or flesh. The invention aims to respond to this problem and it achieves this through a thawing or tempering facility of frozen food products, comprising a receiving chamber of the products to be defrosted or tempered, a ventilation means, in particular directed horizontally or vertically to establish a forced air circulation in the chamber, preferably at a speed greater than or equal to 5 ms -1, a means for heating the products present in the chamber, comprising at least one means for injection or creation of steam in the chamber, in particular by low-pressure steam diffusion, a means of spraying, showering or misting hot water or at ambient temperature, a means for stirring air on the chamber; a hot heat exchanger or an electric heating resistor, and a high frequency electromagnetic system, in particular a microwave, preferably a means of injection or creation of e vapor in the chamber or a resistor or a high frequency electromagnetic system, and a means for cooling the air in the chamber, comprising at least one cold air injection means through a dedicated inlet , a means for stirring air on a cold heat exchanger and a misting means, for showering or spraying cold water in the chamber, and preferably a means for misting or spraying cold water in the chamber, the temperature of the cold water being preferably regulated. This spraying or misting or showering can be carried out by one or more nozzles, which can receive only water, or both air and water. By "showering" it is necessary to understand the formation of a continuous stream of water, and not in the form of droplets. When the spraying or misting of water is carried out with nozzles 20 receiving both air and water, the air sent into the nozzles may be reheated or cooled as appropriate, which may contribute to reheat or cool the water spray or mist. By "means of ventilation" means any fan or turbine for generating a forced air flow in the chamber, the axis of rotation of the fan or turbine is oriented horizontally or vertically or otherwise. The fan or the turbine can be driven by a motor fixed on a wall defining the chamber. Alternatively, moving air is injected into the chamber, for example vertically or horizontally, and produces the forced air flow regardless of the presence of a fan or turbine in the chamber. By "steam injection means" is meant a vapor outlet in the chamber, the vapor being produced outside the chamber, or an in situ production of vapor in the chamber, for example by means of sending liquid water on a hot part causing the vaporization of the water. By "steam creation" in the chamber is meant the formation of vapor by water, especially in the form of droplets, in contact with a surface brought to a temperature above the boiling temperature of the water. By "air cooling means in the chamber" is meant a system for taking calories from the air and venting them out of the chamber. By "means for injecting cold air through a dedicated inlet" means a conduit for blowing cold air into the chamber, preferably at a temperature of less than or equal to 10 ° C. The water sprayed or misted in the chamber can be cooled with the aid of a refrigeration unit or any other source of cold. The installation preferably comprises a means for spraying, showering or misting cold water, better misting, preferably at a temperature below 6 ° C. It is particularly preferred that the heat input be at least 15 by injection or creation of steam in the chamber and that the cooling is carried out by misting water at a controlled temperature, this misting being able to take place at the same time. time as injection or creation of steam. The transfer coefficient at the interface between the food and its environment is 10 to 100 Wm-2.1C1 for air against 500 to 10 000 Wm.2.1Ci for water. The presence of a water mist in the defrosting chamber, due to the possibility of misting water with the aforementioned nozzle (s), thus promotes the transfer of heat between the food product and its environment, creating a film of water on the surface of the products. The injection of water vapor into the thawing chamber is advantageous in that it allows a large amount of heat to be transferred. In contact with the food, the water vapor gives up its latent heat of change of state to the food product, which represents about 2,260 kJ / kg of steam. The heat transfer is all the more effective as the renewal of the contact surface between the food products and the heat transfer fluid (s) is fast. This renewal is achieved by the maintenance of turbulent conditions, which can be achieved by means of ventilation, which is preferably arranged to induce air velocities greater than 5 m.sup.-1, more preferably 10 m.sup.-1.
    [0003] The heating of the air induced by this strong stirring is however mitigated by the means for cooling the air, and preferably by spraying or misting the water in the chamber, thanks to the nozzle or nozzles. The installation according to the invention thus allows the food products to be heated rapidly while avoiding that the surface temperature does not climb too much or too fast, and does not affect the appearance of the food excessively. The invention furthermore makes it possible, by acting on the temperature of the sprayed or misted water, and / or, where appropriate, on that of the air supplying the corresponding nozzles, to regulate the heat input relatively precisely in accordance with the constraints imposed 10 at the surface temperature, and thus control this temperature to the benefit of the quality of thawing. This surface temperature depends, in the invention, on the following parameters: external heat input by the conversion of kinetic energy into heat by ventilation, steam, air and water mist; the transfer of frigories from the frozen heart of the product to the surface, - the contribution of external frigories by the air or the water present in the chamber in the immediate environment of the products. In the first part of defrosting or tempering, the first two parameters can relatively easily equilibrate, while in the second part of defrosting or tempering, the transfer of frigories from the core to the surface is likely to be insufficient to compensate. the heat input induced by the aforementioned heat sources. Indeed, if the regulation can prohibit the injection of steam, ventilation alone can suffice to heat the atmosphere, by converting the kinetic energy 25 of air into heat. Spraying, better misting, cooled water has the advantage of maintaining favorable conditions for surface heat transfer, without allowing runaway surface temperature. In particular, the presence of a cooled water mist can also make it possible to compensate for a longer time the heat conversion of the kinetic energy of a strong ventilation. The quality of the thawing is improved, and some products can, thanks to the invention, present after thawing an appearance that differs very little from that of fresh products before freezing.
    [0004] Depending on the requirements, the installation according to the invention can thus make it possible to simultaneously maintain a cooled water mist, a low pressure steam injection and a high ventilation. The installation may comprise a means of misting hot water or at a temperature greater than or equal to 15 ° C. or at room temperature (20 ° C.). A cooling of the injected or stirred air can take place simultaneously with the introduction of the mist of water cooled by misting water. The installation preferably comprises a means for regulating the temperature of the water spray, delivered by showering or misting to a desired setpoint value as a function of time and / or temperature of the products, in particular of their surface temperature. . This regulating means can also act, if necessary, on the temperature of the air injected into the spray or misting nozzle (s). When the regulation is carried out as a function of time, actions corresponding to time sequences are predefined and executed thanks to a time base. Forced air circulation can be carried out in closed circuit, for example by means of a fan placed in the upper part of the chamber. The installation may comprise a supply to be connected to a sanitary cold water network and the water cooling means may consist of at least one refrigeration unit arranged to cool to a desired temperature, for example at a temperature less than or equal to 10 ° C, the mains water before spraying or misting. This refrigeration unit can also be used to cool the air injected into the chamber and / or stirred in it. The group can be carried by a wall of a frame defining the chamber. The ventilation means is preferably arranged to produce forced air circulation at a speed greater than or equal to 5 ms -1, more preferably at a speed greater than or equal to 10 ms -1, at least one location of the chamber, the air velocity being preferably reduced with the advancement of the defrosting or tempering cycle. The installation may comprise a feed to be connected to a hot water sanitary network or a water heater external to the chamber, so as to be able to deliver by showering, spray or mist the water at a temperature greater than 20 °. C or 25 ° C in the chamber, especially at the beginning of the thawing or tempering process.
    [0005] The means for cooling the air in the chamber may comprise one or more heat exchangers, for example tubes, in which a fluid circulates, for example brine. This brine can be that of a brine network present in the plant, and can also be used to cool the water that is or mist, and if necessary the air injected into the spray nozzles or misting . This brine water can also be cooled by a refrigeration unit specific to the installation and for example fixed to a wall delimiting the chamber. When the installation includes an air inlet and outlet system of the chamber, it can be cold air from the direct external environment of the cell, for example if it is placed in a cold room . According to another of its aspects, the subject of the invention is also a process for thawing or tempering frozen food products present in the chamber of a thawing or tempering plant, in particular having at least one of the characteristics mentioned above. above, this process comprising the steps of: - subjecting the products to be defrosted or tempered to a forced air circulation in the chamber, in particular with an air speed greater than or equal to 5 ms-1, as well as to a steam injection and a shower, spraying or misting of water, the mist, shower or spray water having preferably at the end of thawing or tempering a temperature of less than or equal to 10 ° C., more preferably at least 5 ° C. ° C.
    [0006] The water that is delivered by showering, spraying or misting is preferably at a controlled temperature, especially at a temperature below 10 ° C, better at 6 ° C. It is thus possible to vary the temperature of the sprayed or misted water as a function of time and / or a temperature measured at the surface of the products and / or at the core of the products. This makes it possible to control the surface temperature and thus preserve the quality of the products. Forced air circulation is preferably effected with an air velocity of at least 5 ms-1 in at least one chamber location, more preferably at least 10 ms-1. The initial temperature of the frozen products may be less than or equal to -30 ° C.
    [0007] The injection of steam can take place during the shower or spraying or misting of water, especially cooled water. The forced air circulation can be carried out according to at least two speeds of air velocities, different depending on the defrosting or tempering state of the products, in particular a high speed speed at the beginning of the defrosting process and a low speed diet at the end of thawing or tempering. Of course, the invention is not limited to a modification of the speed and it may, alternatively, remain constant. The steam injection can be interrupted from a certain degree of thawing or tempering of the products, while the showering, spraying or misting of water is maintained. The temperature of the water delivered by showering, spraying or misting after stopping the steam injection is preferably less than or equal to 5 ° C. The temperature of the water delivered by showering, spraying or misting can thus vary from T1 at the beginning of the thawing or tempering process to T2 at the end of said process, with T2 <T1, and preferably T1> 10 ° C and T2 < 6 ° C. The invention further relates to a thawing or tempering apparatus for frozen food products, comprising: a chamber for receiving the products to be defrosted or tempered, a ventilation means, in particular directed horizontally or vertically, to establish a circulation of forced air in the chamber, a means for heating the products present in the chamber, comprising a means for injecting or creating steam in the chamber or a high-frequency electromagnetic system, a means of cooling the air in the chamber; the chamber comprising at least one cold air injection means by a dedicated inlet, a means for stirring air on a cold heat exchanger, and a misting means, showering or spraying cold water into the chamber, and preferably misting or spraying cold water into the chamber. The invention will be better understood on reading the description which follows, of a nonlimiting example of implementation thereof, and on examining the appended drawing, in which: FIG. in perspective, an example of a defrosting or tempering plant according to the invention, and - Figure 2 shows a detail of Figure 1.
    [0008] The defrosting or tempering plant 10 according to the invention, represented in FIGS. 1 and 2, comprises a frame 11, also called defrosting or tempering cell, defining a chamber 12 in which the food products to be defrosted or can be introduced. to temper. The frame 11 is preferably made of stainless steel.
    [0009] A door 13 provides access to the chamber 12 to bring and remove the products, which may be present on a carriage. The installation 10 may comprise, as illustrated, a refrigeration unit 15, which is for example fixed on the frame 11 on the side opposite to the door 13. The chamber 12 can communicate with the outside by an air inlet 21 and a air outlet 22, preferably located on the upper wall of the frame 11. These inlet and outlet can be equipped with non-return valves. The air inlet and outlet valves are open if it is desired to introduce ambient air from outside. This air can be that of a hot zone (25 ° C) or that of a cold zone (4 ° C). The opening may also result from a demand for relative humidity regulation. The air inlet 21 may be provided with a temperature sensor 23 for knowing the temperature of the incoming air. The latter may be cooled air if the cell is placed in a cold room, whose temperature is for example between -10 ° C and + 10 ° C.
    [0010] The installation 10 includes vapor diffusion ramps 30 in the chamber 12. These ramps 30 communicate with steam inlets 31, connected to steam supply pipes, not shown. In the example illustrated, the ramps 30 are two in number, being respectively located near the left and right vertical walls of the frame 11. They each have a vertical section 30a, which extends from the upper wall 16 of the frame 11 over most of the height of the chamber 12, and a horizontal section 30b which extends not far from the floor 17 of the chamber 12. The installation 10 may comprise, as illustrated, one or more heat exchangers 40, present in the chamber 12 to cool the air therein. These exchangers 40 are for example two in number, as illustrated, being present in the upper part of the chamber 12. It can be tubular exchangers water / air, the air of the chamber 12 flowing outside tubes 41, the latter being horizontal and traversed by cold brine water. This is for example cooled by the refrigerating unit 15, or comes from a network of cold water glycolée factory. The installation 10 includes nozzles 50 for misting water or an air / water mixture inside the chamber 12, in order to create a mist of water therein. The particle size of the misted droplets is, for example, of the order of 1 to 60 μm. The nozzles 50 are preferably placed, as illustrated, below the exchangers 40, in the upper part of the chamber 12. The fan 60, whose motor is outside the chamber 12, creates a forced air flow inside the chamber 12, with an air speed greater than 5 ms -1, better 10 ms 1. The axis of the fan 60 can be vertical and located between the exchangers 40. comprise a control unit, also called PLC, programmable to control the operation of the various elements of the installation, to subject the products to defrost, or to temper, conditions adapted to their heating. Various temperature probes are connected to this plant, and the regulation is carried out in particular according to the measured temperatures. The installation 10 may thus comprise several probes, such as a core probe 81, a surface probe 82, a relative humidity probe 83 and an air temperature probe 84. In the case where the nozzles 50 receive compressed air and water, as illustrated, each air or water inlet can be equipped with a corresponding temperature sensor 57, 58. The water supplying the nozzles and the air supplying the nozzles can thus be controlled in temperature. The relative humidity probe 83 can also be used to control the misting according to the programming of the plant, the steam inlet and the air inlet, if, for example, a relative humidity setpoint is set. The regulation can play on the parameter of relative humidity according to the temperature. The vapor which is diffused in the chamber 12 is for example at a temperature of between 99 and 152 ° C. The water which is misted by the nozzles 50 may be cold, warm or hot water, its temperature being preferably controlled by the control unit at the desired temperature, which may vary depending on the time in the defrosting or tempering cycle. The misted water and / or the compressed air is cooled by means of the refrigeration unit 15 in the example illustrated. To carry out a defrosting or tempering cycle, the foods present in the chamber 12, for example arranged on a suitable trolley, on several stages, are subjected for example to: - a diffusion of vapor by the ramps 30, - a circulation of a forced generated by the fan 60, preferably at a speed of at least 5 ms 1, - a mist of water by the nozzles 50. The temperature of the misty water and the air that accompanies this misting can decrease as a function of the core temperature of the food, from more than 10 ° C at the beginning 15 when the food is coldest at less than 6 ° C, for example when the steam injection is interrupted at the end of the cycle. The control unit receives the signals from the temperature probes and controls the solenoid valves for the admission of steam into the ramps 30 and the water spray via the nozzles 50, the speed of the fan 60 and the temperature at which the water is misted by the nozzles, so as to optimize the defrosting or tempering by seeking to advance the temperature of the food as quickly as possible while maintaining the surface temperature of these foods at a sufficiently low value to alter as little as possible the appearance of the food. The invention is not limited to the illustrated example and it is possible, for example, to modify the geometry of the chamber 12, the number and the location of the vapor diffusion ramps 30, the number and location of the nozzles 50 or exchangers 40, and the positioning of the fan 60. In a variant, the misting nozzles are fed only with water under pressure. The misting nozzles may be replaced by spray nozzles which do not create mist but a shower of droplets in the chamber.
    [0011] The expression "comprising one" shall be understood as being synonymous with "comprising at least one" unless the contrary is specified.
