    ARRANGEMENT AND SYSTEM FOR FEEDING BIOMASS MATERIAL TO ATREATMENT PROCESSTECHNICAL FIELDThe present invention relates to feeding arrangements and systems forhydrolysis and pre-hydrolysis processes using Iigno-cellulosic biomass materialincluding biomass material such as annual plants.
    BACKGROUND OF THE INVENTIONHigh pressure or pressurized systems are typical in hydrolysis and pre-hydrolysis processes. Feeding of cellulosic biomass material including annualplants to be treated in a treatment arrangement, for example, an arrangement for apre-hydrolysis process therefore often involves handling of the material underhigher pressures. ln such arrangements it is important to provide a smooth andreliable feeding of the biomass material in order to prevent and avoid, for example,uneven power consumption and problems with so called blow-back flow.
    According to prior art solutions, biomass material is transported to thetreatment process via a feeding arrangement such as a pin drum feeder andfurther to a conveying device which conveys the material to the treatment process.ln typical prior art feeding arrangements, a housing is arranged with anupper inlet opening for receiving the material and a lower outlet opening 15 fordischarging the material to conveyor. Revolving drums are provided in the housingto control the transport and flow rate of the material through the housing. After thematerial has passed the revolving drums, the material falls through the lower outletopening to the plug screw feeder. lt is important to maintain a smooth andcontinuous flow of material into the treatment process. This is crucial inpressurized systems. An example of a process in a pressurized system is a pre-hydrolysis process. Such processes are sensitive to changes in the flow rate. Thematerial is fed to the pin drum feeder from a vertical feeding chute or similar unitconnected to the upper inlet opening of the housing. An effective and smoothaverage flow of material into the pin drum feeder requires that this vertical feedingpipe is completely filled with material during operation. Hence, when the feedingpipe is completely filled with material, the flow into the pin drum feeder will besmooth and continuous. The revolving drums operate to feed the material through2the housing towards the outlet opening in a controlled manner. During the rotationof the drums material is forced through the housing and leaves the drums whenthe weight of the material exceeds the binding strength of the material.
    However, if the binding strength of the material increases, which mayoccur when the material is compressed, it may result in that the material is stuck tothe drums and leave the drums in blocks instead of a smooth stream of material.This results in a discontinuous feeding of material to the conveying device which,in turn, entails varying power consumption and feeding disruptions within theconveying device.
    Thus, there is a need for improved feeding arrangements for feedinglignocellulosic biomass material such as annual plants to a treatment process andan improved system comprising such a feeding arrangement and a method forfeeding lignocellulosic biomass material such as annual plants to a treatmentprocess.
    SUMMARY OF THE INVENTIONAn object of the present invention is to provide improved pressurizedfeeding arrangements and systems for hydrolysis and pre-hydrolysis processesusing lignocellulosic biomass material such as annual plants.
    Another object of the present invention is to provide improved pressurizedfeeding arrangements and systems for hydrolysis and pre-hydrolysis processes oflignocellulosic biomass material, such as annual plants, having a low density.
    A further object of the present invention is to provide improved pressurizedfeeding arrangements and systems for smoothly and continuously feedinglignocellulosic biomass material, such as annual plants, with a high degree ofprecision to a subsequent hydrolysis process.ln the context of the present invention, the term “plug screw feeder” relatesto a feeder comprising a screw or similar rotating means and which is capable offeeding or transporting lignocellulosic material through the feeder at increased ormaintained density of the material and that creates an essentially gas- and fluid-tight plug of the lignocellulosic material towards the end of the feeder. Forexample, according to an embodiment of such a plug screw feeder, a cross-sectional area of the circular housing of the feeder and the screw diameterdecreases in the feeding direction thereby so as to create a decreasing space3between the screw and the housing and thus resulting in an essentially gas- andfluid-tight plug of the lignocellulosic material towards the end of the feeder.According to another embodiment of a plug screw feeder, the cross-sectional areaof the circular housing of the feeder is constant while and the screw diameter andscrew axis increases in the feeding direction thereby creating a decreasing spacebetween the screw and the housing and thus resulting in an essentially gas- andfluid-tight plug of the lignocellulosic material towards the end of the feeder. As theskilled person realizes, there are other embodiments of feeders that achieves thispurpose and thus are included within the definition of the term “plug screw feeder”.
    Further, a force-feeding screw that may be used in the present invention isdescribed in, for example, WO 2013126007.
    According to an aspect of the present invention, there is provided afeeding arrangement for feeding lignocellulosic biomass material such as annualplant material to a hydrolysis process. The feeding arrangement comprises at leastone transportation device for transporting the biomass material towards thehydrolysis process and at least one tearing roll arranged at a predetermineddistance from the at least one transportation device. The tearing roll is providedwith tearing protrusions and is arranged with a predetermined distance to the atleast one transportation device to tear off parts of the transported material toprovide a substantially continuous average flow rate of material.
    According to another aspect of the present invention, there is provided afeeding system for feeding lignocellulosic biomass material such as annual plantmaterial to a hydrolysis process. The system comprises a feeding arrangementincluding at least one transportation device for transporting the lignocellulosicbiomass material such as annual plant material towards the hydrolysis processand at least one tearing roll arranged in connection to the at least onetransportation device. The tearing roll is provided with tearing protrusions and isarranged with a predetermined distance to the at least one transportation device totear off parts of the transported material to provide a substantially continuousaverage flow rate of material. A force-feeding screw is coupled to the feedingarrangement to receive biomass material discharged from the outlet opening of thefeeding arrangement, wherein the force-feeding screw is arranged to transport thebiomass material to the hydrolysis process.4The present invention is based on the insight that by arranging a revolvingtearing roll or grinding roll adjacent to the transportation device at a predetermineddistance from the transportation device it is possible to restrain the block-wisefeeding of material to the subsequent process, for example, a force-feeding screwand/or the plug screw feeder, which often occurs. The tearing roll effectivelyprevents the material blocks from forming and instead disintegrates the material todeliver a smooth and continuous stream of material towards the force-feedingscrew and/or the plug screw feeder.
    According to embodiments of the present invention, a speed of thetransportation device is controlled by a first motor having a variable speed,wherein a rotation of the at least one tearing roll is controlled by a second motorhaving a variable speed and wherein the speed of the at least one tearing roll isvariable independently of the speed of the transportation device.ln embodiments where the present invention is implemented in a systemincluding a conveyer belt, the invention is based on the insight that by arrangingthe revolving tearing or grinding roll adjacent to the discharge end of the conveyerbelt and/or above the transportation side of the conveyer belt it is possible torestrain the block-wise feeding of material to the subsequent process, for example,a force-feeding screw and/or the plug screw feeder, which often occurs. Thetearing roll or rolls effectively prevents the material blocks from forming andinstead disintegrates the material to deliver a smooth and continuous stream ofmaterial towards, for example, a force-feeding screw and/or a plug screw feeder.ln embodiments where the present invention is implemented in a systemincluding drum feeder, the invention is based on the insight that by arranging therevolving tearing or grinding roll below the revolving drums and above the outletopening, it is possible to restrain the block-wise feeding of material to the force-feeding screw and/or the plug screw feeder which often occurs. The tearing rolleffectively prevents the material blocks from forming on the drums and insteaddisintegrates the material that is collected on the drums to deliver a smooth andcontinuous stream of material towards, for example, a force-feeding screw and/ora plug screw feeder.ln preferred embodiments of the present invention, the feedingarrangement is utilized in connection with pressurized treatment processes posingspecial requirements on its feeding arrangement. By the term pressurized is meantthat the pressure in the treatment process exceeds atmospheric pressure. Whenfeeding Iignocellulosic biomass material such as annual plant material to apressurized treatment process, the feeding arrangement must be adapted in sucha way that a back flow of high-pressure material or high-pressure steam from thetreatment process is avoided or at least minimized. ln such application it is ofoutermost importance that the material in the plug screw feeder is fullycompressed and is constantly feed in a smooth stream to the plug screw feeder tominimize the risk of high-pressure material or steam going in the wrong direction,i.e. backwards in relation to the feeding direction of the biomass material. Thepresent invention provides a smooth and continuous feeding of material, with ahigh degree of precision, to the force-feeding screw and/or the plug screw feeder,thereby allowing the material in the plug screw feeder to be fully compressedduring operation.
    According to embodiments of the present invention, the drums of thefeeding arrangement are arranged to co-rotate with respect to each other andthereby transporting the material downwards. ln embodiments, the first andsecond drum is adapted to able to be rotated at variable speed in relation to aproduction flow rate.
    According to embodiments of the present invention, the tearing roll isadapted to able to be rotated at variable speed in relation to a production flow rate.
    The speed of the tearing roll and the speeds of the drums are variableindependently of each other.
    According to embodiments of the present invention, a force-feeding screwsuch as plug screw feeder is arranged essentially perpendicular to the feedingarrangement, e.g. a pin drum feeder, meaning that their respective feedingdirection are essentially perpendicular to each other. ln one embodiment of thepresent invention, the pin drum feeder is arranged to feed material to the plugscrew feeder from above, i.e. a transverse feed into the plug screw feeder inrelation to its feeding direction.
    According to embodiments of the present invention, the plug screw feederis adapted to able to be rotated at variable speed in relation to a production flowrate set by the feeding arrangement. ln other embodiments, the plug screw feederis adapted to be kept at a constant speed being chosen such that the plug screw6feeder has a predetermined degree of filing below the production flow rate set bythe feeding arrangement.
    According to embodiments of the present invention, the tearing roll isarranged such that an outer part of a tearing protrusion is at a first predetermineddistance from an outer surface of the first drum and at a second predetermineddistance from an outer surface of the second drum. The protruding pins areaccording to embodiments provided on the outer surfaces. ln embodiments, thefirst distance and second distance are equal to or lower than a radius and of thefirst and second drum, respectively, and, preferably equal to or lower than half theradius of the first and second drum, respectively. Further, a minimum distancebetween a tip of a pin of a drum and the outer part of the tearing roll is preferably 1cm.

    For the purpose of this disclosure, the term longitudinal refers to thedirection along which a body, part or element has its greatest extension. Further,when the term longitudinal is used in connection with the axes of screws, thelongitudinal axis corresponds to the rotational axis of the screw.
    With reference first to Fig. 1, a feeding arrangement in which the presentinvention can be arranged or implemented will be discussed. The pin drum feeder10 comprises a housing 12 with an upper inlet opening 14 for receiving thematerial and a lower outlet opening 15 for discharging the material to the plugscrew feeder 17. Revolving drums 18 are provided in the housing 12 to control thetransport and flow rate of the material through the housing. After the material haspassed the revolving drums, the material falls through the lower outlet opening tothe plug screw feeder. The material is fed to the pin drum feeder from a vertical8feeding chute or similar unit connected to the upper inlet opening of the housing12. An effective and smooth flow of material into the pin drum feeder requires thatthis vertical feeding pipe is completely filled with material during operation. Hence,when the feeding pipe is completely filled with material, the flow into the pin drumfeeder will be smooth and continuous. The revolving drums operate to feed thematerial through the housing towards the outlet opening in a controlled manner.
    Fig. 2 is a schematic cross-sectional side view illustrating an examplefeeding arrangement according to an exemplifying embodiment of the presentinvention. The feeding arrangement 20 for feeding lignocellulosic biomass materialsuch as annual plant material to a treatment process, e.g. a pre-hydrolysisprocess, comprises a housing 21 provided with an upper inlet opening 22 forreceiving the biomass material and a lower outlet opening 23 for discharging thebiomass material. The biomass material is fed to the inlet opening 22 via a feedingchute (not shown) or similar construction. The feeding pipe may be verticallyarranged allowing the material to fall into the feeding arrangement 20 through theinlet opening 22. Preferably, the feeding pipe is completely filled with materialthereby delivering a smooth and continuous flow of material into the feedingarrangement 20.
    A first and a second revolving drum 24, 25 are arranged in the housing 21.The first drum 24 is arranged to revolve or rotate in a first rotational direction R1and the second drum 25 is arranged to revolve or rotate in a second rotationaldirection Rg. The first drum 24 and the second drum 25 are arranged to co-rotatewith respect to each other and thereby, by rotation of the first and second drum 24,25, transport the biomass material through the housing 21 towards the outletopening 23 (in Fig. 2 in a downward direction). ln embodiments of the presentinvention, a rotational speed of the first and second revolving drum 24, 25 iscontrolled by a motor 26 having a variable speed. Preferably, a rotational speed ofthe first and second drum 24, 25 is controlled using the motor 26.
    At least one tearing roll 27 is arranged at a predetermined distance d1 andd2, respectively, from the first and second revolving drum 24, 25. The tearing roll27 is provided with tearing protrusions 70 and is arranged with a predetermineddistance to the at least one transportation device to tear off parts of thetransported material to provide a substantially continuous flow rate of material.9According to embodiments of the present invention, the tearing roll 27 isarranged such that an outer part of a tearing protrusion 70 (see Fig. 6) is at a firstclosest predetermined distance d1 from an outer surface 74 (see Fig. 6) of the firstdrum 24 and at a second predetermined distance d2 from an outer surface 75 ofthe second drum 25. The protruding pins 66 are according to embodimentsprovided on the outer surfaces 74, 75.ln embodiments, the first distance d1 and second distance d2 are equal toor lower than a radius RA1 and RA2 of the first and second drum, respectively, i.e.d1, d2 s RA1=RA2, and, preferably equal to or lower than half the radius RA1 andRA2 of the first and second drum, respectively, i.e. d1, d2 s 0.5xRA1=RA2.Further, a minimum distance between a tip of a pin 66 and the outer part 70 of thetearing roll 27 is preferably 1 cm.
    As can be seen in Fig. 6, the tearing roll 27 is provided with cuttingelements 70 shaped as protruding knifes. Other conceivable cutting elements areshaped as cutting discs 79 arranged on the tearing roll 77 shown in Fig. 7. Atearing roll with cutting elements is efficient for cutting, for example, annual plants.Such a tearing roll can also be operated at a higher speed.
    According to embodiments of the present invention, a rotational speed ofthe tearing roll 27 is controlled by a motor 28 having a variable speed.ln embodiments of the present invention, the rotational speed of thetearing roll 27 can be varied independently of a rotational speed of the first andsecond drum 24, 25.ln embodiments of the present invention, the feeding arrangement 20 isarranged to feed material to a plug screw feeder 30 in a feeding system 50, seeFig. 3. The plug screw feeder 30 and the feeding arrangement 20 are preferablyarranged perpendicular to each other, i.e. the rotational axis of the plug screw isperpendicular to a feeding direction of the feeding arrangement 20.
    The plug screw feeder 30 is arranged to rotate at a variable speed,wherein the speed of the plug screw feeder operates independently of the drums24, 25 and the tearing roll 27.ln embodiments of the present invention, the feeding arrangement 20 is aso called pin drum feeder. The drums 24, 25 are provided with protruding pins 29,for example cylindrical pins, for transporting the material in a controlled manner.The pin drum feeder is considered to be the “gas pedal” of the system, controllingthe production capacity. The pin drum feeder ensures that an adequate amount ofmaterial is supplied to the plug screw feeder.
    With reference to Fig. 3, a feeding system according to the presentinvention will be described. The system 50 comprises a feeding arrangement 20as described above with reference to Fig. 2.
    An out|et opening 23 of the feeding arrangement 20 is coupled to a force-feeding screw 50, in this embodiment a plug-screw feeder, to feed biomassmaterial to the plug-screw feeder 30. The plug-screw feeder 30 transports thematerial to the treatment process by the rotation of the plug screw 32. The plugscrew 32 is arranged in an elongated and cylindrical housing 31.ln this embodiment of the present invention, the feeding arrangement is apin drum feeder 20. The pin drum feeder is arranged to provide a predeterminedrate of material flow, i.e. the production flow, which is achieved by co-operationbetween the first and second drum 24, 25 and the grinding or tearing roll 27. Therotational speed of the plug screw 32 is then set in relation to the predeterminedrate of material flow in order to achieve a predetermined density increase of thematerial in the plug screw feeder 30. lf the production flow is increased, therotational speed of the plug screw 32 has to be increased to maintain the samedensity in the plug screw feeder 30. lf the rotational speed of the plug screw 32 ismaintained while the production flow increases, the density will increase. Byincreasing the material density in the plug screw feeder an essentially gas- andfluid-tight plug flow of the annular material is created through the plug screwfeeder 30.
    As discussed above, the drums 24, 25 are provided with protruding pins66, for example cylindrical pins, for transporting the material in a controlledmanner.
