Japanese Patent Publication No.53-39507 No. 6-16544 Japanese Utility Model Publication No. 50-89996 Japanese Patent Application No. 2009-51382

By the way, in the process of producing cotton tofu, fried dough, etc. using a conventional continuous molding device, the soy milk coagulated product supplied from the coagulation step is once passed through a filtration device called a water take-up drum or a water take-up belt, Only the soymilk coagulum was poured onto the lower cloth on the receiving side of the continuous molding apparatus (Patent Document 3). As the water take-up drum, there is a type in which a cylindrical wire mesh provided with a spiral feed plate is rotationally driven, and as the water take-up belt, there is a type in which a short endless belt is driven (reference numerals in FIGS. 14A and 14B). S2) By these, the solid-liquid mixture (soy milk coagulated product and soy sauce) in a state where the soy milk coagulated product and "yu" (also referred to as whey, stain, water separation) were separated were supplied. In the method for producing cotton tofu or fried dough, a solid-liquid mixture is produced from a relatively thin soymilk having a soymilk concentration of less than 12% brix, and this is sufficiently separated by a filtration device and then supplied to the continuous molding device 11. Although it is not impossible to produce a pudding (silk-like) soymilk coagulated product with a soymilk concentration of 12% brix or more and difficult to separate, it can be made into cotton tofu, etc. It is difficult to adjust the hardness, and for this reason, it has become common to produce a solid-liquid mixture in which coagulum and soy are mixed using soy milk having a low concentration (the soy milk concentration is about 1 to 12% brix). . In addition, the code | symbol SS of Fig.16 (a) (b) is a washing | cleaning apparatus. )
However, in the supply method through the single-unit filtration device S2, “yu” is removed in advance, so that it is easy to squeeze and mold, but the temperature of the solidified material is lowered, and the binding of tofu and fried dough is poor. In some cases, the elasticity is lost and the quality is deteriorated. In addition, if the separating device called the water collecting drum or the water removing belt is used, it becomes unsanitary or the device becomes complicated and expensive. Further, the opening of the filtration device is relatively coarse, and fine solids are also drained, resulting in a decrease in yield and an excessive wastewater treatment load. If thin soy milk is used, a large amount of "yu" drainage is naturally generated, and a large drainage facility is required, resulting in a large economic burden. In addition, a scraper that scrapes off the coagulated material remaining on the water removal device has been provided in the past, but conversely, the coagulated material is pressed against the cloth and wiped back, or all the coagulated material scraped off is distributed to the distributor (coagulated material). It did not enter the hopper of the distribution supply device. In addition, during long hours of operation, the “boiled” belt becomes clogged, and if water is used for washing, the drainage load increases. If a high-pressure washing machine is used, the tofu lees mixed with water will splash around. It was very unsanitary because it contaminated the surroundings and proliferated with germs on cloths that were used at a warm temperature for a long time and around the shaft.
Furthermore, in the conventional apparatus, when supplying the solid-liquid mixture to the continuous molding apparatus, it was necessary to add a large amount of coagulant in the coagulation step to obtain the soymilk coagulum by adding the coagulant to the heat-treated soymilk. In addition, since the yield is reduced in addition to the loss of taste, it is difficult to economically provide high-quality tofu that retains the flavor of soybeans and fully utilizes the water retention of soy protein. Had.
On the other hand, after solidifying and ripening the solid-liquid mixture into a silk-like (pudding) shape with a belt-type continuous coagulator, it is directly fed to the continuous molding machine by transfer means such as chutes, roughly crushed, dehydrated naturally, There is also a method of molding by sandwiching and compressing with a cloth conveyor belt, but because the slicing is not enough, the uniform breakage of soy milk coagulum is insufficient, the fluctuation of the supply amount due to the sliding condition etc. on the chute There were also disadvantages that occurred. In addition, the bucket-type coagulator solidifies and solidifies the solid-liquid mixture into a silky (pudding) or rag shape, breaks it, supplies the entire amount onto the lower cloth of the continuous molding machine by bucket inversion, and There is also a method of rough breaking on the cloth, further leveling with the leveling device 119 (see FIG. 14), natural dehydration, sandwiching and pressing with the upper and lower fabric conveyors, but the device becomes complicated and unsanitary. In addition, the tofu quality tends to fluctuate corresponding to the interval between bucket reversals.

  Accordingly, an object of the present invention is to provide a coagulated product from a soy milk coagulated product obtained by adding a coagulant to heat-treated tofu or fried dough for hot soy milk without providing a water removal device separately from the conveyor belt for conveyance molding. To provide a method and apparatus for dewatering / molding tofu and fried dough that effectively separates soy sauce (whey) so that the temperature of the soy milk coagulum does not drop, become clogged, or become unhygienic. is there.

The present invention includes an endless lower conveyor composed of a water-permeable material and an endless upper conveyor composed of a water-permeable material disposed above the lower conveyor. Supply the solid-liquid mixture mixed with soymilk coagulum and soup to the side conveyor by solid-liquid supply means or distribution supply means, and supply this concentrated soymilk coagulum on the lower conveyor. Then, natural dehydration is performed by its own weight, and the soymilk coagulum is squeezed between the lower conveyor and the upper conveyor and molded into a predetermined size. The solid-liquid mixture consisting of soy milk coagulum and soy sauce is a soy milk for tofu or fried dough that has been heat-treated, and coagulated with warm soy milk having a concentration of 1-16% brix and 50-99 ° C. by adding a coagulant. (Primary coagulation)-It was obtained by aging.
Here, the upper conveyor of the conventional apparatus may be used as it is, and the soymilk coagulated product cut by the upper conveyor may be supplied to the lower conveyor as it is, or once stored in a storage tank and distributed. You may supply on a lower conveyor from a supply apparatus. Further, it may be cut by the upper conveyor, temporarily stored in a storage tank, and then cut again by the lower conveyor from the distribution supply device.
In addition, the lower conveyor of the conventional apparatus is used as it is (or the extension side of the solid-liquid mixture is slightly extended), and the soy milk coagulated product cut by the lower conveyor is directly used on the lower conveyor. It may be moved to the molding process.
According to the present invention, the soymilk coagulum is molded between the lower conveyor and the upper conveyor. Before entering this molding process, the soymilk coagulum is formed at a predetermined position of the lower conveyor (or the lower conveyor is predetermined). The soymilk coagulated product is removed by removing the whey from the soymilk coagulum and the temperature of the soymilk coagulated product by the conveyor is the same as in the conventional example with a separate water removal device. It can prevent the situation where the tofu is poor and loses elasticity, and the lower conveyor can be moistened with the dyed water containing the coagulant, so the soy milk coagulum adheres to the lower conveyor. Can be prevented.
The water-permeable member constituting the lower conveyor or the upper conveyor is a filter cloth, a non-porous plate, a perforated plate or a caterpillar equipped with a punching plate, a porous steel belt, a porous resin belt, etc. If it is a member of the form which can be used for, it will not specifically limit.

According to the present invention, there is provided a drawer portion in which only the filter cloth of the lower conveyor is drawn from the upper conveyor, and the solid-liquid mixture is cut and formed through the filter cloth. . According to the present invention, the soymilk coagulated product is cut in two layers through a filter cloth and a water-permeable conveyor, so that the cutting is efficiently performed in the form of natural dehydration.
Moreover, according to this invention, it comprises the drawer | drawing-out part which pulled out and provided the filter cloth distribute | arranged on the outer periphery of the said lower side conveyor or the upper side conveyor in a predetermined direction, A coagulant | flocculant is added to the said heat-processed warm soybean milk. The added soymilk coagulated product is cut through the drawer made of the filter cloth, and can be uniformly distributed and supplied onto the lower conveyor. The filter cloth is not particularly limited as long as it has an opening that can capture the soy milk coagulum, but is preferably 10 to 300 mesh. The lower side conveyor or the upper side conveyor may be a caterpillar type conveyor in which a large number of flat plates are attached at predetermined intervals, or a porous member that is water-permeable to the caterpillar, or a porous endless steel belt or resin. It may be a belt.
In the present invention, the driving speeds of the lower conveyor or the upper conveyor and the filter cloths arranged on the outer periphery thereof are the same and synchronized, and may be constant speed continuous driving or intermittent driving. The lower conveyor or the upper conveyor may be slow or stopped, that is, fixed, and the filter cloth may slide on the surface. In this case, the conveyor surface is preferably made of a material (for example, made of resin) that has little friction with the filter cloth.
Further, the pressing parts of the lower conveyor or the upper conveyor are supported by rails fixed to the base, and the upper conveyor has lifting means or pressing means for each unit so On the other hand, it is preferable to be able to adjust and set from a low pressure to a high pressure gradually from the front side (upstream side) to the rear side (downstream side).

The present invention includes a distribution supply device including a storage tank that stores the sliced soymilk coagulated product on the lower conveyor or the upper conveyor, and the soymilk is placed on the lower endless conveyor from the distribution supply device. It is preferable that the solidified material is supplied and molded.
According to the present invention, the chopped soymilk coagulum is stored in a storage tank, and then the soymilk coagulum can be uniformly supplied onto the lower endless conveyor by the distribution supply device. This storage tank is equipped with a stirring means to crush the soymilk coagulum, adjust it so that there is no unevenness by evenly stirring, average the concentration and temperature of the soymilk coagulum, and then the molding process Can be supplied to.

In addition, the present invention provides the soymilk coagulated product obtained by adding a coagulant to warm soymilk and the solid-liquid mixture mixed with soy sauce to the drawer, and cuts the soymilk coagulated product as a concentrated soymilk coagulated product. The concentrated soymilk coagulated product is supplied onto the lower conveyor by a distribution supply means.
According to the present invention, it is produced as a concentrated soymilk coagulum, and the whole amount of the produced soymilk coagulated product is uniformly distributed and supplied onto the lower conveyor, so that the compaction of the pressing / molding process is accelerated. In addition to shortening the length of the pressing / molding apparatus, it is not necessary to increase the amount of the coagulant so much that the solid-liquid mixture that retains the sweetness and taste of soybeans can be suppressed. In addition, small soy milk coagulum can be captured, and it can be slowly sliced to increase the heat retention of the conveyor.

As the present invention, a discharge device or a receiving side of the solid-liquid supply device is provided with a crushing device that roughly breaks the solid-liquid mixture solidified and aged, or in the storage tank of the distribution supply device It is preferable to provide a stirrer that uniformly stirs the soymilk coagulum. When the solid-liquid supply device uses a container, the crushing device is provided on the upper side of the receiving side, or when taken out from the lower side, the crushing device is provided on the discharge side. When the solid-liquid supply device is supplied from a pipe by a metering pump, the crushing device is provided in the pipe path.
According to the present invention, the solid-liquid mixture is preliminarily solidified in the form of a rag, lump, silky tofu, or block (primary solidification), and is roughly broken into an appropriate particle size according to the product and sufficiently whey. Can be subjected to secondary coagulation, that is, squeezing / molding. In other words, there is a method of breaking on the cloth, but the vicinity of the cloth surface cannot be broken, the harmful effect such as biting into the cloth surface occurs, and it takes time until the broken whey is released from water, and it is not fully dehydrated naturally. If it moves to the pressing process as it is (as will be described later, if it is sandwiched between the lower conveyor and the upper conveyor and is compressed), the tofu pressing tends to be uneven or insufficient. Conventionally, the natural dehydration process may be lengthened by increasing the length of the machine (particularly the natural dehydration section) or decreasing the transport speed. However, according to the present invention, it is possible to save space without prolonging the natural dehydration process, and to suppress the temperature drop during pressing (draining) of tofu or fried dough, and binding is achieved with a uniform structure. Good, high quality tofu and fried dough can be obtained. Moreover, when supplying the soymilk coagulum supplied from the batch coagulator, the concentration of soymilk coagulum and the variation of particles can be reduced, and the quality can be further stabilized.

According to the present invention, the upper conveyor or the lower conveyor constituted by the perforated plates of the continuous tofu coagulation machine of the conventional apparatus, the drawer drawn from these, and the endless filter cloth on these conveyors In addition, the solid-liquid mixture is not separated using a solid-liquid supply device, and the solid-liquid mixture that is difficult to cool is supplied without breaking down. It is possible to produce a high-quality tofu / fried dough with good binding by supplying it onto the conveyor and performing secondary solidification (pressing / molding) between the upper conveyor and the lower conveyor. In addition, there is an effect of suppressing tofu cloth attachment, reducing soymilk coagulum lost with the drainage liquid, increasing the product yield, and reducing the drainage load.
According to the present invention, since there is provided a drawer part that pulls out the lower conveyor or the upper conveyor in a predetermined direction, as in the prior art, without providing a water removal device separately from the conveyor belt for conveyance molding, By separating the coagulated product and soy (whey) from the soymilk coagulated product, the temperature of the soymilk coagulated product is prevented from being lowered, clogged or unsanitary. That is, in the past, the coagulated material that entered the cloth, reattached, or was not scraped off by the scraper was washed and drained with the attached cleaning device, but according to the present invention, the coagulated material remains on the fabric. However, since it is bound as a dough in the subsequent pressing process of the upper and lower conveyors, there is no need for washing with water. Since the water flow process is repeatedly performed by slicing, the “steaming” removing belt is not clogged even during long-time operation. Moreover, it does not become an unsanitary state by passing through the conventional filtration device, and the device is hygienic, space-saving and inexpensive.

The soymilk coagulate K remaining on the filter cloth R2 on the upper conveyor C2 side is washed away and used to prevent clogging of the filter cloth R2. Although not shown, scraping means such as a scraper may be provided. During production, the cleaning device Ss is not used, or the cleaning device Ss is not provided, and the filter cloth on which the soy milk coagulum is somewhat adhered may be circulated as it is. Because the soymilk coagulum that adheres and circulates is not washed away, it can be secondarily coagulated and transferred to the product, and the loss of soymilk coagulum is suppressed, and the filter cloth that is warm and familiar is used for the molding process. It is preferable because the tofu has better binding and the drainage load is reduced.
In particular, the first drawer portion Ch1 of the filter cloth R2 on the upper conveyor C2 side is for sending the cut solid-liquid mixture K to the storage tank T2 and the distribution supply device T2h, and the drain pan 3d1 is located on the upper side. It arrange | positions so that the 1st drawer | drawing-out part Ch1 of the filter cloth R2 of the conveyor C2 may be enclosed in a concave shape from the downward side. The cut solid-liquid mixture K sent to the storage tank T2 is uniformly supplied in the width direction and the front-rear direction from the distribution supply device T2h onto the filter cloth R1 on the lower conveyor C1 side.

The filter cloth R2 on the upper conveyor C2 side is arranged along the lead-out portion Ch having a triangular cross section as shown in FIG. That is, a roller 3c for drawing out the filter cloth R2 is provided, and the filter cloth R2 is reversed at the position of the roller 3c. A punching metal is disposed below the filter cloth R2 in the drawer portion Ch. It is preferable. The roller 3c may have one (FIGS. 15 and 16) or two or more rollers, and may have a triangular or polygonal cross section.
As shown in FIG. 12, left and right walls C1d and a pair of side conveyors C1c may be arranged on the left and right sides of the lower conveyor C1. The pair of side conveyors C1c does not need to be arranged over the entire length of the lower conveyor C1, but only the extension C1e.
As shown in FIG. 11, the left and right side wall portions C1b and C1b are also made of a material that does not have a function of cutting the solid-liquid mixture K, but is not a filter cloth. This is because the quality of the tofu / dough (water drainage condition) is equalized by promoting water separation only from the lower filter cloth.

  Partition plates (weirs) 5A and 5B are arranged on the filter cloth R1 on the lower conveyor C1 side. A partition plate 5A (corresponding to a fixed rear wall) on the upstream side of the lower conveyor C1 blocks the return of the soy milk coagulated material cut on the filter cloth R1, and is fixed from above by an arm (not shown). (FIG. 2). The partition plate (weir) 5A, which is the rear wall on the upstream side of the lower conveyor C1, may be simply plate-shaped, or may have a form having a R-shaped (circular arc-shaped) solidified material injection chute function as shown in the figure. A partition plate 5B (flexible detachable front wall; not shown) on the downstream side of the lower conveyor C1 is used at the start of production and is transported along with the transport of the filter cloth R1, and is simply placed on the filter cloth R1. (Fig. 1). Although not shown, the flexible detachable front wall is used at the end of production and as the rear wall.

As another form of the distribution supply device T2h, a storage tank T1 for storing the solid-liquid mixture K is disposed on the front side (previous process) of the continuous molding device Z1, and the solid-liquid supply device (quantitative determination) is provided from the storage tank T1. It is supplied onto the filter cloth R2 on the upper conveyor C2 side of the continuous molding apparatus 1 via the pump 7). The solid-liquid mixture K is produced by adding a coagulant such as bittern to soy milk and stirring it. FIGS. 2 to 10 show an example in which natural filtration is also performed in the extension C1e of the lower conveyor C1, and here, the above-described operation is performed via the solid-liquid supply device (metering pump) 17 from the storage tank T2. The soymilk coagulated product is supplied to the extension C1e of the lower conveyor C1. As the solid-liquid supply devices (metering pumps) 7 and 17, positive displacement metering pumps are used. The positive displacement metering pump is preferably a pump such as a rotary pump, a tubing pump (hose pump), a sine pump, or the like that can supply coarse solids without damaging them. Moreover, a Mono pump, a screw pump, a screw conveyor (pipe shape, trough shape), and a pipe conveyor can also be used. A pump that does not easily generate shearing force is desirable because of its structure, has low pulsation, is quantitative, and has a large diameter (1 inch or more, preferably 1.5 to 5 inches) for both the suction side diameter and the discharge side diameter. A large-scale metering pump that can be supplied with the rotational speed as small as possible so that the coagulated material is not crushed too finely is preferable. The other solid-liquid supply device 7 is not particularly limited as long as it is a supply means (a pump or a conveyor) that can stably feed the fluid containing the whey and the solid-liquid mixture K without uniformly breaking the fluid. However, a sealed form is preferable because it is hygienic and easy to perform automatic cleaning. Centrifugal pumps, gear pumps, diaphragm pumps, plunger pumps, etc. that lack quantitativeness, shearing force that crushes solid-liquid mixtures finely, and those that have check valves, retention parts, etc., that are not suitable for solids supply It is not preferable. As shown in FIG. 3, the outlet poured into the continuous molding apparatus 1 may be branched into a plurality. A plurality of positive displacement metering pumps 7 may be provided. Further, the flow rate of the positive displacement metering pump 7 may be provided with a flow meter and PID control may also be performed. It may be automatically controlled so as to interlock with the continuous molding apparatus Z1.
The nozzle 17a at the tip of the solid-liquid distribution and supply means 17 is straight as shown in FIGS. 4 (a) and 4 (c), but bends toward the partition plate 5A as shown in FIGS. 4 (b) and 4 (d). You can do it. Further, as shown in FIG. 4 (e), the soy milk coagulated material cut from the nozzle 17a is once put in the container 17b to be stored, and then supplied to the filter cloth R2 so as to overflow from the container 17b. Things may be used.

  The 2nd storage tank T2 is a tank which stores the cut soy milk coagulum, is provided with a discharge port below, and supplies the soy milk coagulum to the lower conveyor C1. A distribution supply device T2h is built below the second storage tank T2, but the storage tank T2 is equipped with a stirring means so that the soy milk coagulum is roughly broken or stirred uniformly so that there is no unevenness. After adjusting or averaging the concentration and temperature of the soymilk coagulum, it can be supplied to the molding step 2C.

A crushing device 8 and a leveling device 19 for roughly breaking the solid-liquid mixture K supplied from the distribution supply device T2h or the solid-liquid supply device 17 are provided (see FIG. 13A). Moreover, the solid-liquid mixture K supplied from the solid-liquid supply device 17 may be roughly broken to provide a roughing device 8.
The crushing device 8 includes a wire mesh, a lattice-shaped container, a type 8a (FIG. 6 (a)) in which a wire mesh is provided on a cylindrical body, a type 8b (FIG. 6 (b)) in which a screw and wings are provided, and a large number of holes. 8c (FIG. 6 (c)), in which a plate having a screw is provided, type 8d (FIG. 6 (d)) in which a screw-shaped member is rotated by a motor M, and type 8e (FIG. 6 (in) in which a comb-shaped member rotates. e)), type 8f (FIG. 6 (f)) in which the whisk type rotates, type 8g (FIG. 6 (g)) in which the saw type rotates, or screw type or comb tooth type that moves up and down (FIG. 6 (h)) can be used. By using these crushing devices 8, the soymilk coagulum obtained by slicing it becomes a relatively uniform block of tofu H, and water separation of whey in the natural dehydration process and the pressing press process in the subsequent process. Averages speed and thickness of tofu and fried dough, and has the effect of equalizing moisture. For example, as shown in FIG. 14, the leveling device 19 has a structure in which a flat plate is moved up and down by a cylinder 19 c so as to fit in a concave conveyance path formed by a lower conveyor C <b> 1 and a pair of side conveyors C <b> 1 c. It is possible to use any leveling device that operates in a normal manner.

Next, a case where tofu is produced using the tofu / fried dough dewatering / molding apparatus Z1 of the present embodiment will be described.
FIG. 8 is a flowchart for explaining the dehydration / molding process of the tofu / fried dough (tofu) according to the present embodiment. The primary coagulation step G1 is a coagulation step in which a coagulant is added to soy milk to harden it. If the soy milk is thin, the coagulation conditions are strong (when there are many coagulants, the coagulation temperature is high, etc.) When an object is broken, water separation (yuyu) is separated in the process, and a coagulated product (soymilk coagulated product) and soy are mixed, which is also called a solid-liquid mixture. The secondary coagulation step G2 is generally referred to as a pressing / molding step 2C, and refers to a step in which the coagulation product is destroyed, and the secondary coagulation in the step of molding and molding, that is, the phenomenon of coagulation of the coagulation products occurs. (Receiving the solid matter and filtering the soy sauce), thereby forming a block-like or sheet-like tofu H (cotton tofu or fried dough).
In the primary coagulation step G1, a solid-liquid mixture K having coagulated solidified product and soup is produced, and the solid-liquid supply device 7 is used to separate the solid-liquid mixture K in the storage tank T1 without separating the whey. When quantitatively supplied onto the filter cloth R2 of the first inclined part Ch1 of the drawer part Ch of the conveyor C2, the filter cloth R2 performs natural dehydration only by the weight of the soy milk coagulum (FIGS. 1A and 1B). )). That is, the whey is separated from the solid-liquid mixture K having the soymilk coagulum and the soup in the primary coagulation step G1. The chopped soy milk coagulum is sent to and stored in the storage tank T2, and is discharged from the distribution supply device T2h below the storage tank T2. Soy sauce is collected through the drain pan 3d1 and discharged from the outlet 3d. In the present embodiment, the filter cloth R1 on the endless upper conveyor C2 side is used by being pulled out in a predetermined direction, so that the filter cloth area is 20 times or more that of the conventional water removal belt, There is no worry of clogging.
Next, when the soymilk coagulum collected in the storage tank T2 is quantitatively and evenly distributed and supplied onto the filter cloth R1 on the lower conveyor C1, the lower conveyor C1 conveys it for a predetermined distance, and the upper conveyor C2 Upon reaching the position, the press from above is performed by the upper conveyor C2. That is, as the continuous molding apparatus Z1 moves forward from the receiving port, natural filtration occurs (natural dehydration is performed for a predetermined distance), and then the upper cloth C2 side filter cloth R2 is applied to the upper and lower cloths. By being conveyed in the state of being sandwiched, squeezing from low pressure to high pressure is gradually applied, and block-shaped or sheet-shaped tofu H is manufactured (FIG. 1A). For example, the solid-liquid mixture K is cut by the upper conveyor C2 and once stored in the storage tank T2, and then cut again by the lower conveyor C1, or the storage. Instead of passing through the tank T2, what is cut by the upper conveyor can be cut again by the lower conveyor as it is. Further, the storage tank T1 in which the solid-liquid mixture K is placed may be tilted to supply the whole amount to the drawer portion Ch. In this case, since the soup in the solid-liquid mixture K is first supplied to the drawer portion Ch, the upper conveyor C2 is warmed by boiling, so that binding and clogging occur even if the subsequent soymilk coagulated product is supplied. It is difficult and has the effect of not cooling the soymilk coagulum suddenly.

Here, in the present embodiment, it is produced as a solid-liquid mixture (first coagulation step G1) obtained by adding a coagulant to hot soymilk and coagulating, and the total amount of the produced solid-liquid mixture is the upper side. It becomes possible to supply to the drawer part Ch of the filter cloth 2 on the conveyor C2 side. The soymilk concentration when obtaining the solid-liquid mixture K is generally 1 to 7% brix for fried tofu, and preferably 6 to 16% brix for tofu. In the present invention, 3-15% brix soymilk is particularly preferable. In the case of oil-fried dough, freshly-fried dough, cotton tofu, etc., it is desirable to crush in advance and sufficiently water-release the whey before pressing. In particular, the fried dough needs to be squeezed to a moisture of 80% wt or less. Therefore, in the conventional manufacturing method, it is common to adjust the solid-liquid mixture K to a state in which it is easy to release water, such as increasing the amount of coagulant. . That is, even in the case of cotton tofu and deep-fried dough, the yield was low.
However, by adding the whole amount according to the present embodiment, the chopped soymilk coagulated product is hard to cool, the solid-liquid mixture K does not need to increase the amount of coagulant so much, and it becomes difficult to cause cloth attachment, so that the sweetness and taste of soybeans can be reduced. The retained solid-liquid mixture K can be suppressed to a solidified state, and it has become possible to produce a high-quality fried product and cotton tofu product that has a flavor and is well-bound and elastic.
Further, the temperature of the solid-liquid mixture K is preferably 60 ° C. or higher, for example. However, if the whey is removed in advance, the cloth of the continuous molding device Z1 and its supporting caterpillar plate are cold or low. If the device is cooled by the influence of outside air temperature or wind, the temperature of the solid-liquid mixture K will be 60 ° C. or lower, and the worst will be 40 ° C. or lower. . On the other hand, in this embodiment, since the whey (soybean) of the soymilk coagulated product is not removed in advance, the temperature range of 60 to 95 ° C. can be maintained in the molding process as described above, and it can be rapidly cooled. Absent.
In the present embodiment, the solid-liquid mixture (crushed and rough state including whey) is fed by the positive displacement metering pump 7 and poured directly onto the cloth of the continuous molding apparatus Z1. By incorporating the total amount of K, even if the room temperature is low or the apparatus is cooled, the temperature drop of the solid-liquid mixture K can be minimized, and the tofu having good elasticity is obtained from the start-up of the apparatus. It is possible to suppress the occurrence of loss such as with cloth.
In addition, the degree of prior whey removal changes slightly due to changes in soybean quality and production conditions, but it may affect the height of tofu (dough) obtained under certain conditions such as pressing pressure and time. Therefore, the present invention makes it easy to secure stable product dimensions. In addition, although the process G2 (molding process 2C) which solidifies the solid-liquid mixture K in supply process S1 has a preferable continuous type, the form driven to a batch type may be sufficient.

(Second Embodiment)
In the present embodiment, in addition to the configuration of the first embodiment (the configuration of the drawer portion Ch of the upper conveyor C2), the lower conveyor C1 is a solid liquid that is the front side of the continuous molding apparatus 1. On the side where the supply device 7 (17) is arranged, it is arranged with an extension C1e (FIGS. 7A, 7B and 7C). That is, a roller 6 for pulling out the filter cloth R is provided, and the filter cloth R1 is reversed at the position of the roller 6, and a punching metal Pm is temporarily provided below the filter cloth R1 of the extension C1e. It is arranged. However, the punching metal Pm may be omitted. A partition plate (weir; the rear wall) 5A is disposed on the upstream side of the extension C1e of the filter cloth R. Further, the nozzle (hose) 7a (17a), which is the solid-liquid supply device 7 (17), reciprocates in the width direction of the filter cloth R1, thereby pouring the solid-liquid mixture K evenly. In addition, even if there is no said extension part C1e, although it cuts by the drawer | drawing-out part Ch of the said upper side conveyor C2, the structure which is configured so that the second cut is performed by having the said extension part C1e It is.

  Therefore, when the solid-liquid mixture K supplied from the solid-liquid supply device 7 (17) is supplied onto the extension C1e of the filter cloth R1, it is naturally filtered (dehydrated) by its own weight. In particular, when there is no punching metal, it is sufficiently filtered naturally (dehydrated) by the extension part C1e of only the filter cloth R, and is transported for a predetermined distance by the lower conveyor C1 in a sufficiently filtered state. Pressurized with C2. In addition, although there may be a side wall and a side conveyor in the left and right sides of the lower conveyor C1, it is preferable to have no filtration function like the filter cloth R1.

(Third embodiment)
In the present embodiment, a drawer C2h is provided on the lower conveyor C1 (FIG. 9). That is, a roller 3c for pulling out the filter cloth R2 is provided, and the drawer part C2h is provided so that the filter cloth R1 is lifted upward at the position of the roller 3c. Moreover, the slope part Ch1 similar to the conventional water-removal belt is comprised, and the sliced soybean milk coagulum is stored in the storage tank T2. A drain pan 3di is arranged below the first inclined surface portion Ch1, and the cut water is discharged from the drain tank Cd. Further, a slope Cds to which the solid-liquid mixture K is supplied from the container 9 is provided.

Therefore, when the solid-liquid mixture K supplied from the solid-liquid supply device 7 is supplied onto the drawer portion C2h of the filter cloth R1, it is naturally filtered (dehydrated) by its own weight and is put into the storage tank T2, and this Distribution is supplied from the storage tank T2 onto the filter cloth R1 on the lower conveyor C1 side for molding. The filter cloth R1 is cut out of the soymilk coagulated product whey in the drawer C2h before entering the molding process, so that the temperature of the soymilk coagulated product is lowered and the tofu has poor binding and elasticity. The situation where it is lost can be prevented, and the lower conveyor or the upper conveyor can be wetted with the soup (including the coagulant), so that the soy milk coagulum can be prevented from adhering to the filter cloths R1, R2. Similarly to the above, although not shown, the cleaning device Ss is not used during the production, or the cleaning device Ss is not provided, and the filter cloth on which the soymilk coagulum is adhered may be circulated as it is, thereby suppressing the loss of the soymilk coagulum. Further, since the filter cloth in a warmed and familiar state is used in the molding process, the binding of tofu is improved, the tofu cloth is also suppressed, and the drainage load is reduced.
The supply of the soy milk coagulum to the drawer C2h is performed on the lower conveyor C1 of the third embodiment together with the supply of the soy milk coagulum to the drawer Ch on the upper conveyor C2 of the first embodiment. In addition, natural filtration at C1e of the lower conveyor C1 may be performed. In other words, according to the present invention, natural filtration by a conveyor can be performed stepwise twice or three times, and it can be produced as a concentrated soymilk coagulum, and each conveyor can be prevented from entering the molding process while being cooled, Prevents cloth from sticking and keeps the device more hygienic during operation.

(Fourth embodiment)
In the present embodiment, a conventional apparatus is used. The upper conveyor C2 is not provided with a drawer (FIG. 17), and the solid-liquid mixture K is solidified on the upper side of the upper conveyor C2. It supplies with the liquid supply apparatus 7, and cuts using the water permeability. Further, a leveling device 19 for moving the flat iron 19b up and down is provided. In addition, in FIG. 17 of this Embodiment, the filter cloth R2 is also not distribute | arranged.
When the solid-liquid mixture K is supplied by the solid-liquid supply device 7 on the upper side of the upper conveyor C2, it is cut and naturally filtered (dehydrated) by its own weight. The storage tank T2 is distributed and supplied for molding onto the lower conveyor C1 side.
In the present embodiment, there is an advantage that a conventional apparatus can be used, but the position where the solid-liquid mixture K is supplied by the solid-liquid supply apparatus 7 can be changed, or various changes can be made so that it can be easily tilted and cut. .

(Fifth embodiment)
In the present embodiment, a continuous molding apparatus 1 including a lower endless conveyor C1 and an upper endless conveyor C2 that are driven along the longitudinal direction of the base 2, and the continuous molding apparatus 1 It is comprised from the storage tank T for supplying the soymilk coagulum K, and the solid-liquid supply means 7 (FIG. 18 (a) (b), FIG. 2). FIG.18 (b) is a figure which shows the state by which the tofu H is manufactured using the apparatus of Fig.18 (a).
The storage tank T stores the soymilk coagulum K produced by adding a coagulant to the heat-treated soymilk, and the soymilk coagulum K in the storage tank T is automatically fed tofu through the solid-liquid supply means 7. Supplied to a molding apparatus (continuous molding apparatus) 1. Although the production of tofu H will be described as an example, the present invention can also be applied to the production of tofu, for example, deep-fried, fresh-fried, fried, deep-fried, tofu, cotton tofu, soft cotton tofu and the like.

  The endless conveyor C1 on the lower side is wound around the front driving roller 2A and the rear driven roller 2B, and when one of the rotating rollers 2B is driven to rotate through the driving means, it is conveyed in the direction of the arrow in FIG. Is done. In addition, the side wall conveyor and the side wall part are not provided in the left and right of the endless conveyor C1 on the lower side.

The lower endless conveyor C1 is a rigid plate conveyor made of steel, stainless steel, or metal such as titanium in which plate plates are arranged at predetermined intervals, and may be called a caterpillar. . In addition, even if there is no porosity and unevenness | corrugation which can permeate | transmit a plate board, it can permeate | transmit also from the clearance gap between each plate board. The adjustment of the amount of water flow is determined by the width and pitch of the plate plate. Further, on the upstream side of the lower endless conveyor C1, the filter cloth R is extended outward (upstream side) from the plate plate motion track, and there is a porous punching metal or uneven so as to support the extended filter cloth. You may comprise so that natural spin-drying | dehydration may be accelerated | stimulated by providing the support tool which has arrange | positioned several plates and a simple round bar.
The lower conveyor C1 can be used with plate plates arranged at predetermined intervals. This plate conveyor can be made of, for example, a metal such as stainless steel such as SUS304 or SUS430, more heat-resistant polypropylene, It may be made of synthetic resin such as fluororesin, or may be configured in a concave shape, and its lower surface is made of the above materials, and the recessed portions on both sides of the concave shape are filtered using a flexible material such as silicon rubber. The cloth R may be hard to be damaged. The plate conveyor or the plate may have a large number of holes or may be coated with fluororesin. In addition to the horizontal movement, the conveyor may be moved in an oblique direction such as uphill or downhill, or moved up and down in the vertical direction. The plate plate is prevented from being deformed by the lower-side conveyor or the upper-side conveyor having the above-described configuration and the upper-side endless filter cloth R or the lower-side endless filter cloth R. In addition, excess water can be discharged from the predetermined gap through the upper and lower filter cloths R. For example, in the case of adopting a structure in which the upper endless conveyor is moved up and down by lifting means arranged on the base, the pressing force is constant when pressurizing the tofu H through the filter cloth R. Can be. The same applies to the upper conveyor C2 described later.

A filter cloth R is disposed on the lower conveyor C1. The filter cloth R is for dehydrating the solid-liquid mixture K naturally, and is arranged so as to cover the upper surface of the lower conveyor C1 made of punching metal. The filter cloth R is preferably disposed with an extension C1e on the side where the solid-liquid supply means 7 is disposed on the front side of the continuous molding apparatus 1 (FIGS. 24A and 24B). c)). That is, a rotating roller 6 for pulling out the filter cloth R is provided, and the filter cloth R is reversed at the position of the rotary roller 6, and a punching metal is arranged below the filter cloth of the extension C1e. It is preferable that
The filter cloth R is configured as an endless belt, is plain weave with fluororesin monofilament, and is heat-treated (shrink-proof) before weaving. The surface that comes into contact with tofu and fried dough is calendered. Applied to a tofu and fried dough, and a filter cloth for dehydration and molding of a molding device, the filter cloth being configured as an endless belt, and the monofilament yarn in the longitudinal direction of the endless belt is polyvinylidene Fluoride (PVDF), monofilament yarn in the transverse direction is a tetrafluoroethylene perfluoroalkoxy group copolymer (PFA), and the surface which comes into contact with tofu / fried dough is preferably subjected to calendering. In addition, the porosity is 15 to 78%, the wire diameter of the fluororesin monofilament yarn is 0.1 to 3.0 mm, the minimum bending radius is 500 mm or less, and the contact when water is dropped at room temperature The maximum stress that expresses the peel strength between the filter cloth and the tofu / fried dough is 7.2 gf / calender with a corner of 60 degrees or more, a reduction ratio of 40 to 80%. It is preferable that it is cm ² or less.
The yarn used for the filter cloth is preferably a resin monofilament yarn. Further, the monofilament yarn may have any shape as the spinneret for extruding the melt. The yarn to be used is heat-treated before weaving so that the shrinkage due to heat when it is made into a filter cloth is reduced, and deformation of the filter cloth from the eyes is prevented. Furthermore, the combination of weaving density, yarn wire diameter, hole area ratio, etc., adjusts the mechanical resistance and dewatering efficiency, etc., smoothes the unevenness of the folded part by calendering, improves the releasability of the filter cloth, It was found that the target filter cloth was obtained.
The yarn used is preferably a monofilament yarn. Monofilament yarn is slightly inferior in particle capture performance, but it is suitable for the production of tofu H and fried dough because it has good removability due to washing and less clogging and good cake peelability. A filter cloth using a multifilament yarn has particle trapping properties, but is unsuitable because it is clogged and uncleanable and unsanitary. The spun yarn has excellent particle trapping properties at the time of filtration, but the filtration surface becomes fuzzy, so that the cake peelability is deteriorated.
The weaving method was plain weaving in order to leave the same marks as cotton cloth. Plain weave has excellent cleaning properties and is effective for natural dehydration. Natural dehydration has important implications for final products, such as product properties and averaging in the process of dehydration and molding of tofu. Further, in the cleaning with the high-pressure cleaning nozzle and the continuous tofu molding apparatus 1, it is necessary to prevent “from eyes” and meandering during operation. “Eyes from the eyes” are likely to occur in the weft direction in the continuous tofu molding apparatus 1, but can be prevented by a combination of the wire diameter of the weft and the weave density.
The material of the thread used for the filter cloth has no water absorption, and the filter cloth is easy to dry, which is also effective in preventing bacterial growth. Therefore, it is preferable to use a fluorine-based resin that does not absorb water. The material of the yarn may be other resin filter cloths such as polyester and polypropylene that have been used in the past, but the peelability from tofu is poor, the incidence of defective products is high, and the tofu H attached to the filter cloth It may be difficult to remove the dirt and the cleaning performance may be poor. Any type of fluororesin may be used, but it has relatively good peelability. Among them, tetrafluoroethylene perfluoroalkoxy group copolymer (PFA) has the best peelability of tofu H, and then polyvinylidene fluoride. (PVDF), polytetrafluoroethylene (PTFE). However, the strength of warp yarn is insufficient with PFA alone, and if the wire diameter is increased in order to give strength, the opening becomes smaller and the filtration performance deteriorates. By using PVDF for the warp, the filtration performance can be maintained and the filter cloth can be given strength.
By applying a calendering process to the filter cloth, the contact surface between the filter cloth and the tofu / fried dough becomes smooth, so that the soy milk coagulum is captured and the peelability of the tofu / fried dough is improved. In calendering, when pressed, it is compressed and crushed. At that time, the rolling reduction of the filter cloth may be 40 to 80% of the wire diameter, but 61 to 65% is preferable. Further, the calendering is performed by adjusting the material of the calender roll, the surface form, the number of calender rolls, the speed, the pressure, the temperature, and the humidifying conditions.
With fluororesin-based materials, shrinkage and deformation when using a filter cloth can be suppressed by performing heat treatment at the yarn stage. In the case of a continuous dehydration / molding apparatus, the shrinkage rate when using the filter cloth is preferably within 3% in the longitudinal direction of the apparatus, within 2% in the lateral direction, and both within 1% after the filter cloth is mounted. In addition, although it is expensive, polyether-ether-ketone resin (PEEK) is one of the preferred materials as well as the fluororesin.

An upper conveyor C2 is arranged above the lower conveyor C1, and the upper conveyor C2 is shorter than the length of the lower conveyor C1, and thus a predetermined length is set on the front side of the upper and lower conveyors. Region C1e is formed, from which a solid-liquid mixture is supplied. A filter cloth R is also disposed on the upper conveyor C2.
The plate plate C may have a structure in which a lower surface portion C1a having a concave cross section and left and right side wall portions C1b and C1b on both sides thereof are provided (FIG. 28). In this case, the concave lower surface portion C1a is made of a punching metal having a large number of holes, and the side wall portions C1b and C1b are made of resin or metal without holes. The left and right side walls C1b and C1b are also made of a material that does not have a function of cutting out the solid-liquid mixture, not a filter cloth, although the cloth is arranged. This is because the quality of the tofu / dough (water drainage condition) is equalized by promoting water separation only from the lower filter cloth. As shown in FIG. 29, left and right walls C1d and side conveyors C1c may be arranged on the left and right sides of the lower conveyor C1. The side conveyor C1c does not have to be arranged over the entire length of the lower conveyor C1, and only the portion of the extension C1e.

  On the filter cloth R, partition plates (weirs) 5A and 5B are arranged. A partition plate 5A on the upstream side of the lower conveyor C1 (corresponding to a fixed rear wall) blocks the return of the solid-liquid mixture K on the filter cloth R, and is fixed from above by an arm (not shown). FIG. 19). A partition plate (weir) 5A, which is a rear wall on the upstream side of the lower conveyor C1, has a solidified material injection chute function having an R-shaped cross section (arc shape) as shown in the figure. The partition plate 5B (the flexible detachable front wall) on the downstream side of the lower conveyor C1 is conveyed along with the conveyance of the filter cloth R, and is simply placed on the filter cloth R (FIG. 18). Although not shown, a flexible removable rear wall is also used at the end of the final product.

A storage tank T that stores the soy milk coagulum K is disposed on the front side of the continuous molding apparatus 1, and is supplied from the storage tank T onto the filter cloth R of the continuous molding apparatus 1 through the solid-liquid supply means 7. . The soymilk coagulum K is produced by adding a coagulant such as bittern to soymilk and stirring it. The solid-liquid supply means 7 supplies the soymilk coagulum K stored in the storage tank T, and a positive displacement metering pump is used in the present embodiment. The positive displacement metering pump is preferably a pump that can supply coarse solids without damaging them, such as a rotary pump, a tubing pump (hose pump), a sine pump, and a cascade pump. Moreover, a Mono pump, a screw pump, a screw conveyor (pipe shape, trough shape), and a pipe conveyor can also be used. A pump that does not easily generate shearing force is desirable because of its structure, has low pulsation, is quantitative, and has a large diameter (1 inch or more, preferably 1.5 to 5 inches) for both the suction side diameter and the discharge side diameter. A large-sized pump that can be supplied with the rotation speed as small as possible so as not to break up the coagulated material too finely is preferable. The other solid-liquid supply means 7 is not particularly limited as long as it is a supply means (a pump or a conveyor) that can stably feed the fluid containing the whey and the solid-liquid mixture K without uniformly breaking the fluid. However, a sealed form is preferable because it is hygienic and easy to perform automatic cleaning. Centrifugal pumps, gear pumps, diaphragm pumps, plunger pumps, etc. that lack quantitativeness, shearing force that crushes solid-liquid mixtures finely, and those that have check valves, retention parts, etc., that are not suitable for solids supply It is not preferable. The outlet for pouring into the continuous molding apparatus 1 may be branched into a plurality. A plurality of positive displacement metering pumps 7 may be provided. Further, the flow rate of the positive displacement metering pump 7 may be provided with a flow meter and PID control may also be performed. It may be automatically controlled so as to interlock with the continuous molding apparatus 1.
The nozzle 7a at the tip of the solid-liquid supply means 7 is straight as shown in FIGS. 21 (a) and 21 (c), but is bent toward the partition plate 5A as shown in FIGS. 21 (b) and 21 (d). But it ’s okay. Further, as shown in FIG. 21 (e), the solid-liquid mixture K from the nozzle 7a is once put in the container 7b to be stored and then supplied onto the filter cloth R so as to overflow from the container 7b. But it ’s okay.

  Here, it is preferable that the solid-liquid mixture K supplied from the solid-liquid supply means 7 is roughly broken and the rough breaking means 8 is provided. The crushing means 8 includes a wire mesh, a grid-like container, a type 8x (FIG. 23 (a)) in which a wire mesh is provided on a cylindrical body, a type 8y (FIG. 23 (b)) in which a screw and a wing are provided, and a number of holes. A type 8y provided with a plate having the same can be used (FIG. 23C). The rough breaking means 8 may be broken roughly when stored in the storage tank T (FIGS. 18A and 18B). These crushing means 8 make the solid-liquid mixture K into a relatively uniform block, and has the effect of stabilizing the water separation speed of the whey in the natural dehydration process and the pressing press process in the subsequent process.

  Therefore, when producing tofu using the tofu / fried dough dewatering / molding apparatus 1 according to the present embodiment, the solid-liquid supply means 7 does not separate the whey of the solid-liquid mixture K in the storage tank T. Is quantitatively supplied onto the filter cloth R on the lower conveyor C1 provided with the endless belt-like filter cloth. Since there is no upper conveyor C2 in the region where the solid-liquid supply means 7 is disposed, natural dehydration is performed by the filter cloth R only by the weight of the solid-liquid mixture K. And if it conveys for the predetermined distance by the lower side conveyor C1, it will reach the position where the upper side conveyor C2 is arranged, and the pressure press from the upper side by the upper side conveyor C2 will be performed. That is, as the continuous molding apparatus 1 advances from its receiving port, natural filtration occurs (natural dehydration is performed for a predetermined distance), and then the upper cloth of the upper conveyor C2 is applied and sandwiched between the upper and lower cloths. By being conveyed in the state, the squeezing from low pressure to high pressure is gradually applied to produce tofu with a predetermined shape (block shape).

Here, it is preferable that the concentration of soy milk when obtaining the solid-liquid mixture K is 2 to 7% brix for frying and 6 to 16% brix for tofu. And in the case of fried dough, fresh fried dough, cotton tofu, etc., it is desirable to squeeze them after preliminarily breaking them and separating the whey sufficiently. In particular, the fried dough needs to be squeezed to a water content of 80% wt or less. Therefore, conventionally, it has been usual to adjust the solid-liquid mixture to a state where it can be easily separated, such as increasing the amount of coagulant. That is, even in the case of cotton tofu and deep-fried dough, the yield was low.
However, according to the present embodiment, it is not necessary to increase the amount of the coagulant so much, it is possible to suppress the solidified state of the solid-liquid mixture K that retains the sweetness and taste of soybeans, and it has a high quality with flavor and elasticity. It has become possible to finish fried products and cotton tofu products.
The temperature of the solid-liquid mixture K is preferably 60 ° C. or higher, for example. However, if the whey is removed in advance, the cloth of the continuous molding apparatus 1 and its supporting caterpillar plate are cold or low. If the device is cooled by the influence of outside air temperature or wind, the temperature of the solid-liquid mixture K will be 60 ° C. or lower, and the worst will be 40 ° C. or lower. . On the other hand, in this embodiment, since the whey (soybean) of the soymilk coagulated product is not removed in advance, the temperature range of 60 to 95 ° C. can be maintained in the molding process as described above, and it can be rapidly cooled. Absent.

In the present invention, there is no conventional filtering means for removing water separation (also referred to as “simizu”, “yu”, or “whey”) between the positive displacement metering pump of the solid-liquid mixture and the continuous molding apparatus receiving port. Since the solid-liquid mixture (crushed rough block state including whey) is fed by the positive displacement metering pump 7 and poured directly onto the cloth of the continuous molding apparatus 1, a method of incorporating the entire amount of the solid-liquid mixture Can minimize the temperature drop of the solid-liquid mixture K even if the room temperature is low or the device is cold, and it can be made tofu with good elasticity from the start-up of the device, with cloth The occurrence of loss can be suppressed.
In addition, the degree of prior whey removal changes slightly due to changes in soybean quality and production conditions, but it may affect the height of tofu (dough) obtained under certain conditions such as pressing pressure and time. As a result, it is easy to secure stable product dimensions by incorporating the entire amount.

(Sixth embodiment)
Although the present embodiment includes a lower conveyor C1 and an upper conveyor C2, the lower conveyor C1 is an extension C1e on the side where the solid-liquid supply means 7 that is the front side of the continuous molding apparatus 1 is disposed. (FIGS. 24A, 24B, and 24C). That is, a sprocket 6 for pulling out the filter cloth R is provided, and the filter cloth R is inverted at the position of the sprocket 6, and a punching metal Pm is temporarily provided below the filter cloth R of the extension C1e. It is arranged. However, the punching metal Pm may be omitted. A partition plate (weir; the rear wall) 5A is arranged above the extension C1e of the filter cloth R. Further, when the nozzle (hose) 7a, which is the solid-liquid supply means 7, reciprocates in the width direction of the filter cloth R, the soymilk coagulum K is poured evenly.

  Therefore, when the solid-liquid mixture K supplied from the solid-liquid supply means 7 is supplied onto the extension C1e of the filter cloth R, it is naturally filtered (dehydrated) by its own weight. In particular, when there is no punching metal, it is sufficiently filtered naturally (dehydrated) by the extension part C1e of only the filter cloth R, and is transported for a predetermined distance by the lower conveyor C1 in a sufficiently filtered state. Pressurized with C2. In addition, although there may be a side wall and a side conveyor in the left and right sides of the lower conveyor C1, it is preferable that the filter cloth R does not have a filtering function.

  Here, as shown in FIGS. 25 (a) and 25 (b), the crushing means 8 is an agitator 8A that is placed in the storage tank T and agitates, as shown in FIG. 25 (c). A cylindrical pipe 8B on which a wire mesh is arranged is arranged in the supply line, and the solid-liquid mixture K is crushed when supplied from the storage tank T to the continuous molding machine 1 via the positive displacement metering pump 7 But it ’s okay. Further, the stirring device for the storage tank T may also serve as the roughing means 8, or the metering pump 7 itself may be provided with a breaking function 8.

Further, the solidifying process of solid-liquid mixture K may be a batch type in addition to a continuous type.
As an example in the case of the continuous type, a method of solidifying by passing through a pipe G1 called pipe solidification or in-line solidification as shown in FIG. 26 (c) may be used. It may be solidified by a belt-type coagulator G2, G3 or the like as shown in FIG. In the continuous type, the supplied soymilk coagulum K is appropriately broken by providing the roughing means 8 and is received in the storage tank T as one form. In the case of a pipe coagulator, the form once received in the soymilk coagulum tank at the outlet, and the other, as shown in FIG. 26 (c), the soymilk feed metering pump connected to the soymilk tank and the coagulant tank The pipe outlet 7a for continuously feeding the obtained coagulant-containing soy milk is directly molded using a system for mixing the coagulant with the coagulant feed metering pump and the in-line type mixing / stirring device. It may be supplied to the lower conveyor of the machine or once received in the soymilk coagulum tank T and poured into the lower cloth by the positive displacement metering pump 7. In addition, the form which provides a grid tooth like a mincing machine on the metering pump 7 piping or the exit vicinity 7a is also considered. In the steel belt type continuous coagulator, the breaking device 8 may be driven to reciprocate by a single unit, or a plurality of front and rear units may be provided.

  In the case of a batch type, a crushing process is performed in a solidification bucket as shown in FIG. 27, and the solid-liquid mixture is once received in the balance tank T, and a crushing means 8A is provided in the balance tank T. Also good. The continuous coagulator may be a so-called boat coagulator. In the case of a boat-shaped coagulator, there is also a fixed mechanism that breaks by climbing over the bottom as a shape that once climbs the bottom in the middle of the boat-shaped tank.

  A batch type coagulator is a bucket coagulator or the like, in which buckets or mold boxes are circulated in a simple movement, and a series of operations such as soy milk weighing, coagulation stirring, aging, (breaking), reversing (filling) are processed in units of one bucket To do. At the time of bucket reversal, the form in which the soymilk coagulum is once received in the soymilk coagulum tank T is also one form. In the case of a batch type, a ripening bucket is used, and round rods or a rough punching plate are moved up and down, or a device 8 is installed that breaks up and down while rotating the screw blades. There is also a method of dropping on a rough wire mesh when the bucket is reversed.

  In addition, there is also a form (for example, a steel belt type continuous coagulation machine and a continuous molding machine manufactured by Takai Seisakusho Co., Ltd.) which are incorporated on the cloth of the molding machine (provided with transfer means and breaking means as appropriate) without using a metering pump. In this form, breakage of the bottom surface of the soymilk coagulated product (portion in contact with the lower cloth) tends to be insufficient (since there is a risk of rubbing the cloth with a breaking device and damaging the cloth). Once this is received in the soymilk coagulation tank, the whole can be sufficiently broken, and it tends to be homogeneous tofu. The same can be said for boat-shaped coagulators.

(Manufacture of frying)
6 kg of US soybean produced in 2008 was immersed in well water overnight and drained to obtain 13 kg of pickled soybean. Using a soymilk production plant (Takai Seisakusho 3000; batch kettle triple type) and a soymilk squeezer (Takai Seirius 2 series), weighed 13 kg of pickled soybeans (13 kg / min) and ground water 21 L (18 L / Min) is added to the seed box, and 11L is added with water, etc., sent to the kettle, heated with stirring with 0.2 MPa water vapor, 98 ° C. for 3 minutes and 30 seconds Immediately after heating, 19 L of return water was added, and the mixture was sent to a squeezer to separate the okara to obtain about 75 L of 5% brix 75 ° C. soy milk. This was made into one batch and repeated to produce about 30 kettles / hour.

Next, using a boat-type continuous coagulator, 5% brix 75 ° C. soy milk is flowed at a flow rate of 2200 L / hour, and a 5% magnesium chloride aqueous solution (about 6% w / v) as a coagulant is simultaneously flowed at a flow rate of 110 L / hour. Poured and solidified by natural convection. Immediately after coagulation, the coagulated material was agglomerated in the form of cotton, and yellowish green “yu” separated. After ripening for about 7 minutes, it was crushed by a rush that was set up near the middle of the boat-shaped tank, and after aging for another 3 minutes, it was poured into a soy milk coagulum tank with yellow-green “yu”. The soymilk coagulum tank is equipped with a stirring blade that can slowly and greatly agitate the rotary pump with a large aperture of 2 inches, with an inlet / outlet diameter of 2 inches while holding the coagulum so that it does not break apart so that it does not break finely. (Nakakin, 0.75 kw) 17 at a low speed (about 60 rpm) and quantitatively at a flow rate of 2310 L / hr, continuous molding machine (Takai Seisakusho; soybean about 3 kg / hr type) Z1 upper conveyor C2 The solid-liquid mixture K was fed into the drawer portion Ch so as to have a thickness of about 50 to 60 mm. The solid-liquid mixture K was made uniform in the drawer portion Ch. After about 4 minutes of natural dehydration, the product is collected in the storage tank T2 and then discharged. After that, it is sandwiched between the upper cloth and the lower cloth R over about 20 minutes and gradually reduced in pressure (0.002 MPa as the load on the tofu) ) To high pressure press (0.015 MPa). A twill-woven endless belt-shaped filter cloth (air permeability 10,000 ml / cm ² / min) using flat monofilament yarn (width 1.5 mm x thickness 0.6 mm) made of polypropylene for both upper and lower cloth used. After the pressing step, a belt-shaped fried dough (conventional) having a thickness of 8 mm was obtained from the outlet of the continuous molding machine. Next, the dough is cut into a square shape with a side of about 45 mm and supplied to a continuous fryer (automatic fryer manufactured by Takai Seisakusho; 80 mm square), and the temperature is extended at a low temperature (100 to 120 ° C .; the latter half is about 30 Hz). Fried sushi products (80 mm × 80 mm) at 20,000 sheets / hour, fried for 10 minutes at high temperature (180 to 190 ° C.) for 10 minutes. Usually for sushi fried, 4% brix soy milk is often used, but even with a slightly darker 5% brix soy milk, it is possible to produce a fried dough that is more elastic than before. The quality could be improved in a more favorable direction as fried sushi, which is finer than the product, elastic in the skin, strong and less oil-absorbing. In addition, the amount of yu drainage was reduced by about 20%.

(Manufacture of tofu)
Pickled soybeans obtained by immersing US soybeans produced in 2008 overnight in well water and draining them from them. 3), continuously weigh (6.6 kg / min), grind while adding 10 L / min of grinding water, receive the raw koji in the seed box, and use the rotary pump to remove the raw kama. It was continuously sent to the heating section at a flow rate of 6 kg / min, and 0.5 to 0.1 MPaG of water vapor was directly blown into the five-stage steam supply section and heated. After heating at about 105 ° C. for 6 minutes, it was sent to the squeezer to separate the okara to obtain 13.5% brix 80 ° C. soy milk at a flow rate of about 750 L / hour.

Next, using the dewatering / molding device (steel belt type continuous coagulator, continuous molding machine) Z1 of FIGS. 1 (a) and 1 (b), 720 L of the 13.5% brix 80 ° C. soy milk is used. Flowed at a flow rate of / hour, and a commercially available emulsified bitter coagulant ("Magnesfine TG" manufactured by Kao, 36% magnesium chloride 36.6% w / w) as a coagulant is injected into the soymilk pipe at a flow rate of 6 L / hour, Immediately after passing through an emulsifier-dispersing machine (PRIMIX pipeline homomixer, 5000 rpm), the mixture was immediately poured into a steel belt shape and coagulated into a silky shape (pudding shape). After ripening for about 10 minutes, it was roughly broken by a crushing device 8 provided at the outlet, and then the whole amount was dropped into a storage tank 9 (T1) for storing soymilk coagulum. The storage tank 9 (T1) is not provided with a stirrer, does not store a large amount of coagulum in the storage tank 9 (T1), and has a large-diameter rotary pump with an inlet / outlet diameter of 3 inches (first-in first-out). Sucked with Nakakin (0.75 kw) 7, quantitatively with low speed rotation (about 40 rpm) at a flow rate of 750 L / hr, continuous molding machine (Takai Seisakusho; soybean about 3 kg / hr type; upper and lower fabrics are PVDF A plain woven filter cloth R using a monofilament yarn having a wire diameter of 0.4 mmφ and an air passage amount of 20,000 ml / cm ² / min, 40 mesh) Z1 has a drawer portion Ch of about 45 to 55 mm in the solidified height. The solid-liquid mixture K was made uniform. After that, leveling is performed by a leveling device 19 that raises and lowers flat iron (see FIG. 13 (a)), and after natural dehydration for about 3 minutes, it is sandwiched between upper and lower cloth R1, R2 over about 15 minutes. Then, it was molded by applying a low pressure (0.001 MPa as a load applied on tofu) to a high pressure press (0.005 MPa). A belt-shaped cotton tofu H having a thickness of 40 mm is obtained from the outlet of the continuous molding machine Z1, cut into a rectangle of about 75 × 100 mm on a side, and continuously packed in a tofu pack (2B). After sealing and sealing, boiled at 92 ° C for 50 minutes, cooled with 2 ° C chiller water for about 90 minutes, and cooled to a core temperature of 5 ° C or less to produce a cotton tofu product (300 g) at about 1800 pcs / hour. . There is no fluctuation of tofu quality as seen in the bucket reversal interval of the bucket type coagulator as in the past, and there is less uneven breakage of the soy milk coagulum as in the case of the conventional belt type continuous coagulator, In this example, the quality of the tofu was not changed, the coagulant was not used excessively, the tofu was elastic, and the state of the cut was uniform.
As a result, in the conveying process in the continuous molding machine Z1, a rapid temperature drop does not occur as in the conventional device using the filtration device, and there is a flavor compared to the belt-like cotton tofu produced by the conventional device. The result was a high quality cotton tofu product with elasticity.
