Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a rapid centrifugal dehydration device for tofu. Background Art

[0002] The production of fried tofu requires the processes of wrapping, pressing, cooling and frying successively. Before the frying process, it is required to drain the water of the fried tofu blank (i.e., the tofu block before frying) as much as possible. However, due to the production process of fried tofu, the temperature cannot be too high when draining water, so high-temperature drying cannot be used. The existing air-drying methods on the market are generally natural air-drying. After the tofu block is formed, the large piece of tofu is first cut into small pieces with a knife, and then placed in a cool place to be naturally air-dried. Sometimes a fan is used to blow to accelerate the air-drying speed.

[0003] There are the following problems in adopting the traditional tofu water draining process method:

[0004] (1) After the tofu is formed, when the whole large piece of tofu is cut into small pieces manually, many cuts are needed horizontally and vertically, which is not fast enough and slows down the air-drying speed;

[0005] (2) After the tofu is formed, it needs to be turned over and placed on the ground. This process may cause damage to the tofu block and reduce the forming rate of fried tofu;

[0006] (3) It is greatly affected by the weather. It is not easy to air-dry in rainy weather and can only be air-dried indoors, and the air-drying speed of the tofu is even slower. It is also greatly affected by the season. The air-drying speed is fast in summer with high temperature and slow in winter with low temperature;

[0007] (4) When placed outdoors, there may be mosquitoes, flies, etc. These insects stay or feed on the tofu block, causing pollution to the tofu;

[0008] (5) In addition to the evaporated water, a part of the water also flows to the ground, causing the ground to be slippery and possibly making the staff slip and get injured.

[0009] In view of the above problems, there are the following solutions:

[0010] (1) Extrusion dehydration: This is the main solution for tofu dehydration on the market now. The tofu extrusion dehydration device uses the external force extrusion to quickly dehydrate the tofu. After extrusion, the tofu is cut into pieces and placed on the table, and a fan is used to accelerate the draining of water. This method is simple and easy to operate, but it has high requirements for the control of the force. At the same time, the tofu may be broken during the extrusion process, and the efficiency and effect of this method for tofu dehydration are relatively poor.

[0011] (ii) Vibration dehydration: Place multiple molds filled with tofu on the device, and use the inertia of the mold vibration to shake out the water. However, if vibration is used to dehydrate the tofu blocks in one direction, more than half of the travel distance and efficiency will be wasted (because the return journey does not dehydrate); if vibration is used to dehydrate the tofu blocks in both directions, part of the water inside the tofu blocks is not effectively dehydrated due to the frequent bidirectional inertial force, which also affects the dehydration efficiency. In addition, the intensity of the vibration is not easy to control, which can easily cause the tofu to break during the up and down shaking process. The environmental noise pollution caused by vibration dehydration is also relatively large.

[0012] (iii) Centrifugal dehydration: Centrifugal dehydration utilizes the stable centrifugal force (essentially a constant centripetal acceleration) of uniform rotary motion to continuously remove moisture from the inside of the tofu block. Since this dehydration method is continuous, stable and easy to control, its dehydration efficiency is significantly higher than vibration dehydration and extrusion dehydration, and the working noise is also very low. Although some patent documents mention the use of centrifugal dehydration in the process of making tofu. However, most of them use general centrifugal dehydrators, and there have been no related patent reports on special dehydration devices for the rapid centrifugal dehydration of small and thin tofu such as whole plates of fried tofu blanks. In response to this problem, this patent provides a special dehydration device for the rapid centrifugal dehydration of whole plates of tofu, especially fried tofu blanks.

[0013] If a simple centrifugal dehydration method is used in which the tofu blocks are placed horizontally and dehydrated in a horizontal rotation, it is difficult to quickly dehydrate the water inside the ordinary tofu blocks due to their large width. The tofu blocks used to make fried tofu are relatively thin. If centrifugal dehydration is performed along the thickness direction of the fried tofu block, the water inside is easier to escape. However, the overall width of the whole plate of fried tofu block is very wide, and it is easy to collapse if it is placed vertically directly. Therefore, this patent designs a special mold assembly, which uses a special cutting tool in the mold assembly to first cut the whole plate of fried tofu block into blocks, and relies on the partition isolation and support function of the cutting tool to prevent the small tofu blocks that have been separated from the whole plate of fried tofu block from being collapsed when the whole plate of fried tofu block is placed vertically, and then the whole plate of fried tofu block placed vertically can be subjected to horizontal rotation dehydration. Utility Model Content

[0014] In view of the above situation, in order to overcome the current technical defects, this patent first designs a set of turntable components, the edge of which has a positioning and fixing slot mechanism, and then fixes the cut tofu blocks in a special mold component, and the mold component is vertically installed in the positioning and fixing slot mechanism, and then horizontal rotation and dehydration are performed. The plate that fixes the tofu in the mold assembly has seepage holes and is designed with a slope, so that the water thrown off by the tofu under the action of the rotating centrifugal force can flow out along the slope. Controlling the rotation speed, that is, the size of the centrifugal acceleration, can control the dehydration speed of the tofu.

[0015] The technical solution adopted by the present utility model is as follows: The rapid centrifugal dehydration device for tofu provided by this solution includes a mold assembly, a turntable assembly, a column, fan blades, a support base, bearings, and a reduction motor. The upper and lower ends of the hollow rotating shaft of the turntable assembly are respectively rotationally and coaxially fitted with the column through two sleeved bearings. The cylindrical lower end of the column is coaxially and fixedly connected to the upper end surface of the disc-shaped support base. A lower turntable is provided at the lower end of the turntable assembly, and a group of universal ball wheels are evenly distributed below the lower turntable at the same radius. The bottom of the universal ball wheels is closely attached to the circular base guide rail of the support base. A first gear is coaxially and fixedly connected to the lower end of the column. The first gear is meshed with a second gear, and the second gear is fixedly connected to the motor rotating shaft of the reduction motor. The bottom of the reduction motor is fixedly connected to the upper end surface of the support base.

[0016] Among them, the mold assembly includes, from top to bottom, a cover plate, a first layer of gauze, cutting knives, set screws one, a second layer of gauze, a mold, set screws two, and a water drainage plate. Among them, the cutting knives are formed by intersecting and fixing a group of horizontal cutting knives and a group of vertical cutting knives into a whole, and are embedded into the cover plate card slots of the cover plate covered with a first layer of gauze. To reliably connect the cover plate and the cutting knives, a group of set screws one are screwed into the screw holes of the cover plate and embedded into the pin holes two of the cutting knives. The side protrusions of the cover plate are embedded into the side grooves of the mold. A group of set screws two are screwed into the screw holes of the mold and embedded into the pin holes one of the cover plate to reliably connect the cover plate and the mold. A second layer of gauze is provided between the cutting knives and the mold. The side protrusions of the mold are further embedded into the water outlet grooves of the water drainage plate, thus assembling into an integral mold assembly. The back of the water drainage plate is provided with an inclined section that is high in the middle and low on both sides, facilitating the flow of water to the water outlets on both sides.

[0017] Among them, there is a cluster of air vent holes on the surface of the cover plate, and there is also a cluster of water seepage holes on the bottom wall of the inner cavity of the mold.

[0018] Furthermore, another important feature of the design structure of the mold assembly of this patent is that it is suitable for multiple mold assemblies to be stacked and sleeved for wrapping and centrifugal dehydration. After stacking and sleeving, centrifugal dehydration can, on the one hand, complete the dehydration of multiple groups of tofu blocks at one time, and on the other hand, can simultaneously achieve the dual dehydration effects of extrusion dehydration and centrifugal dehydration. Therefore, it can significantly improve the efficiency and effect of the batch dehydration operation of tofu blocks. In the process of wrapping and pressing tofu blocks, multiple mold assemblies need to be stacked layer by layer for extrusion molding and extrusion dehydration. If multiple mold assemblies can be used for stacked dehydration operation during centrifugal dehydration, the efficiency can be significantly improved.

[0019] Furthermore, the multi-layer mold components of this patent are stacked on top of each other mainly in such a way that when stacking, the mold side protrusions of the upper layer of mold components are inserted into the mold side grooves of the lower layer of mold components. Only the topmost layer retains the cover plate among the mold components of each layer. The drain plates of the middle layers are directly pressed on the tofu blocks of the lower layer of mold components. During the subsequent pressing operation after stacking, by applying pressure to the cover plate of the topmost layer and adding the self-weight stacking of each layer of mold components, the extrusion molding and extrusion dehydration of the tofu in each layer can be achieved.

[0020] Furthermore, during the subsequent centrifugal dehydration operation after stacking, the drain plates of the mold components face outward and the cover plates face inward, and the whole is rotated for centrifugal dehydration. At this time, the tofu in the inner cavities of each layer drains out water under the action of centrifugal force. At the same time, the overall centrifugal force of the inner layer of mold components is applied to the tofu blocks of the adjacent outer layer of mold components through its drain plates, thereby achieving the extrusion dehydration effect.

[0021] Specifically, under the dual action of the above-mentioned centrifugal dehydration and extrusion dehydration, the water drained from the tofu in the inner cavities of each layer of molds flows outwards through the gauze from the water seepage holes, flows through the inclined section of the drain plate, then passes through the horizontal interface of the water outlet channel of the mold, and finally flows outwards through the vertically connected water outlet channels of each layer.

[0022] Through the above structural design, the separated water of each layer will not flow from the tofu of the previous mold to the tofu of the next mold, avoiding secondary soaking. The concave-convex nested cooperation between each layer also makes the stacking neater and more reliable, and the overall force on the tofu blocks in the mold components is more uniform.

[0023] Specifically, the turntable assembly includes a hollow rotating shaft, a lower turntable, an upper turntable and a top cover. The upper and lower ends of the hollow rotating shaft are fixedly connected to the upper turntable and the lower turntable coaxially respectively. The upper part of the upper turntable is fixedly connected to the top cover coaxially. A group of support baffles are fixedly connected between the upper turntable and the lower turntable. A group of positioning and fixing card slot mechanisms are installed near the outer side between the upper turntable and the lower turntable. A group of fan blades are evenly distributed and fixedly connected to the outer cylindrical surface of the hollow rotating shaft of the turntable assembly.

[0024] Specifically, the positioning and fixing card slot mechanism includes a rear long baffle, a lower side baffle, an upper side baffle, a hinge front cover plate, a front movable baffle and a locking screw. There is a group of shallow concave platforms with the same width as the mold components on the outer side above the lower turntable. A group of lower side baffles and rear long baffles are fixedly connected to the two sides and the rear edge line of the concave platform respectively. A group of upper side baffles and rear long baffles are also fixedly connected correspondingly on the outer side below the upper turntable. One narrow side of the hinge front cover plate is hinged to the outer side above the upper turntable.

[0025] Specifically, when placing the mold assembly, press a narrow side of the mold assembly against the concave platform and vertically place it into the semi-open card slot formed by the concave platform, the lower side strip and the rear long strip. Then, lower the front cover plate of the hinge and press it against the outer side of the mold assembly. At the same time, the two side strip holes of the front cover plate of the hinge are sleeved into the mold side protrusions of the mold assembly to reliably fix the mold assembly.

[0026] Wherein, there are two lower convex platforms under the front movable strip, which can be embedded into the two waist-round holes outside the concave platform, and lock the front cover plate of the hinge and the mold assembly. The locking screw can be screwed into the screw hole of the lower turntable, and the front small cylinder of it can be embedded into the round hole of the front movable strip to reliably lock the front movable strip. In addition, both sides of the front movable strip can be embedded into the grooves outside the lower side strip to more reliably fix the mold assembly.

[0027] The beneficial effects achieved by the present utility model with the above structure are as follows: The present utility model is a tofu rapid centrifugal dehydration device, and its advantages are as follows:

[0028] 1. In this application, a special cutting tool for tofu blocks is designed, which can cut a whole piece of tofu into several small pieces at one time, and this cutting tool plays a role of partition isolation and support in the dehydration device, ensuring that the shape of each small piece of tofu is not damaged when dehydrating in a vertically placed state.

[0029] 2. In this application, a set of special mold assemblies for centrifugal dehydration of tofu blocks is designed. This mold assembly is suitable for vertical placement, horizontal rotation dehydration, and is also suitable for multi-layer stacking and sleeving for wrapping and pressing and centrifugal dehydration. When dehydrating by centrifugation after multi-layer stacking, the dual dehydration effects of extrusion and centrifugation can be achieved simultaneously; in addition, the water discharged between each layer does not affect each other, and this design can significantly improve the efficiency and effect of batch dehydration operation of tofu blocks.

[0030] 3. In this application, a set of special dehydration device suitable for rapid centrifugal dehydration of whole-board deep-fried tofu blank blocks is designed. In the device, the whole-board deep-fried tofu blank blocks adopt a centrifugal dehydration method of vertical placement and horizontal rotation dehydration, supplemented by air blowing, draining and cooling from the inside to the outside.

Detailed implementation mode

[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0042] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0043] The technical solution adopted by the present utility model is as follows: As Figure 1 and Figure 7 shown, the tofu rapid centrifugal dehydration device provided by this solution includes a mold assembly 1, a turntable assembly 2, a column 3, fan blades 4, a support base 6, bearings 7 and a reduction motor 10. The upper and lower ends of the hollow rotating shaft 21 of the turntable assembly 2 are respectively rotationally and coaxially fitted with the column 3 through two sets of bearings 7. The cylindrical lower end of the column 3 is coaxially fixed to the upper end surface of the disc-shaped support base 6. A lower turntable 22 is provided at the lower end of the turntable assembly 2. A set of universal ball wheels 5 are evenly installed below the lower turntable 22 with the same radius. The bottom of the universal ball wheels 5 is closely attached to the circular base guide rail 61 of the support base 6. A first gear 8 is coaxially fixed to the lower end of the column 3. The first gear 8 is meshed with a second gear 9. The second gear 9 is fixed to the motor rotating shaft 101 of the reduction motor 10. The bottom of the reduction motor 10 is fixed to the upper end surface of the support base 6.

[0044] As Figure 2 shown, the mold assembly 1 includes, from top to bottom, a cover plate 11, a first gauze 18, a cutting knife 12, a set screw one 15, a second gauze 19, a mold 13, a set screw two 16 and a water drainage plate 14. Among them, the cutting knife 12 is formed by a set of horizontal knives 121 and a set of vertical knives 122 intersecting and fixed as a whole, pressing a first gauze 18, and being embedded into as Figure 3Among the cover card slots 114 of the shown cover plate 11, in order to reliably connect the cover plate 11 and the cutting tool 12, a set of set screws one 15 are screwed into the screw holes 112 of the cover plate 11 and embedded into the pin holes two 123 of the cutting tool 12. The cover side ribs 111 of the cover plate 11 are embedded into the die side grooves 131 of the die 13. The set screws two 16 are screwed into the screw holes 132 of the die 13 and embedded into the pin holes one 113 of the cover plate 11 to reliably connect the cover plate 11 and the die 12. A piece of gauze two 19 is separated between the cutting tool and the model. The die side ribs 133 of the die 13 are further embedded into the water outlet slots 141 of the water drainage plate 14, thus assembling into an integral die assembly 1. The back of the water drainage plate 14 is provided with an inclined section 142 that is high in the middle and low on both sides, facilitating the flow of water to the water outlets 141 on both sides.

[0045] As Figure 3 shown, there is a cluster of air vent holes 115 on the surface of the cover plate 11.

[0046] As Figure 4 shown, there is also a cluster of water seepage holes 134 on the bottom wall of the die cavity 137 of the die 13.

[0047] Another important feature of the design structure of the die assembly of this patent is that it is suitable for stacking and sleeving multiple layers of die assemblies for wrapping and centrifugal dehydration. After stacking and sleeving, centrifugal dehydration can, on the one hand, complete the dehydration of multiple groups of tofu blocks at one time, and on the other hand, can simultaneously achieve the dual dehydration effects of extrusion dehydration and centrifugal dehydration. Therefore, it can significantly improve the efficiency and effect of the batch dehydration operation of tofu blocks. In the process of wrapping and pressing the tofu blocks, multiple die assemblies need to be stacked layer by layer for extrusion molding and extrusion dehydration. And when centrifugal dehydration is carried out, if multiple die assemblies can be stacked for dehydration operation, the efficiency can be significantly improved.

[0048] As Figure 6 shown is a schematic diagram of the upper and lower stacking and sleeving of the multi-layer die assemblies of this patent. When stacking and sleeving, the die side ribs 133 of the upper layer die assembly are embedded into the die side grooves 131 of the lower layer die assembly. Only the cover plate 11 is retained in the topmost layer among the die assemblies of each layer. The water drainage plates 14 of the middle layers are directly pressed on the tofu blocks 17 of the lower layer die assembly. During the wrapping and pressing operation after stacking, by applying pressure to the cover plate 11 of the topmost layer and adding the superposition of the self-weights of the die assemblies of each layer, the extrusion molding and extrusion dehydration of the tofu of each layer can be realized;

[0049] During the centrifugal dehydration operation after stacking, the water drainage plates 14 of the die assembly face outwards and the cover plates 11 face inwards, and the whole is rotated for centrifugal dehydration. At this time, the tofu blocks 17 in the die cavities 137 of each layer drain out water under the action of centrifugal force; at the same time, the overall centrifugal force of the inner layer die assembly is applied to the tofu blocks 17 of the adjacent outer layer die assembly through its water drainage plate 14, thus realizing the extrusion dehydration effect;

[0050] Under the dual actions of the above-mentioned centrifugal dehydration and extrusion dehydration, the water drained from the tofu in the inner cavities 137 of each layer of the mold flows outwards along the path indicated by the dotted arrow from the water seepage holes 134, flows through the inclined section 142 of the water discharge plate 14, then passes through the horizontal interface 136 of the water outlet channel of the mold 13, and finally flows outwards through the vertically connected water outlet channels 135 of each layer. Figure 6 To prevent the tofu material from being squeezed into the water seepage holes 134 of the mold 13 or the air holes 115 of the cover plate 11 during the extrusion and centrifugal dehydration processes, a second gauze 19 and a first gauze 18 are respectively laid on the inner walls of the tofu block in contact with the mold 13 and the cover plate 11.

[0051] Through the above structural design, the separated water of each layer will not flow from the tofu block of the previous mold to the tofu block of the next mold, avoiding secondary soaking. The concave-convex nested cooperation between the layers also makes the stacking neater and more reliable, and the overall force on the tofu block 17 in the mold assembly 1 is more uniform.

[0052] As shown in the figure, the turntable assembly includes a hollow rotating shaft 21, a lower turntable 22, an upper turntable 23 and a top cover 25. The upper and lower ends of the hollow rotating shaft 21 are coaxially and fixedly connected to the upper turntable 23 and the lower turntable 22 respectively. The upper part of the upper turntable 23 is coaxially and fixedly connected to the top cover 25. A group of support baffles 24 are fixedly connected between the upper turntable 23 and the lower turntable 22. A group of positioning and fixing slot mechanisms 26 are installed near the outside between the upper turntable 23 and the lower turntable 22. A group of fan blades 4 are evenly distributed and fixedly connected to the outer cylindrical surface of the hollow rotating shaft 21 of the turntable assembly 2.

[0053] As Figure 7 shown, the positioning and fixing slot mechanism 26 includes a rear long baffle 261, a lower side baffle 262, an upper side baffle 263, a hinge front cover plate 264, a front movable baffle 265 and a locking screw 266. There is a group of shallow concave platforms 221 equal in width to the mold assembly 1 on the upper outer side of the lower turntable 22. A group of lower side baffles 262 and a rear long baffle 261 are respectively fixedly connected to the positions flush with the two sides and the rear side line of the concave platform 221. A group of upper side baffles 263 and a rear long baffle 261 are also correspondingly fixedly connected to the lower outer side of the upper turntable 23. A narrow side surface of the hinge front cover plate 264 is hinged to the upper outer side of the upper turntable 23.

[0054] As Figure 8 shown, the positioning and fixing slot mechanism 26 includes a rear long baffle 261, a lower side baffle 262, an upper side baffle 263, a hinge front cover plate 264, a front movable baffle 265 and a locking screw 266. There is a group of shallow concave platforms 221 equal in width to the mold assembly 1 on the upper outer side of the lower turntable 22. A group of lower side baffles 262 and a rear long baffle 261 are respectively fixedly connected to the positions flush with the two sides and the rear side line of the concave platform 221. A group of upper side baffles 263 and a rear long baffle 261 are also correspondingly fixedly connected to the lower outer side of the upper turntable 23. A narrow side surface of the hinge front cover plate 264 is hinged to the upper outer side of the upper turntable 23.

[0055] When placing the mold assembly 1, a narrow side of the mold assembly 1 is placed close to the concave platform 221, and is vertically placed in a semi-open slot surrounded by the concave platform 221, the lower side stop bar 262, and the rear long stop bar 261. Then the hinge front cover plate 264 is lowered and close to the outer side of the mold assembly 1. At the same time, the two side bar holes 2641 of the hinge front cover plate 264 are inserted into the mold side convex strips 133 of the mold assembly 1 to reliably fix the mold assembly 1; two lower convex platforms 265 are provided below the front movable stop bar 265. 1, can be embedded in the two waist holes 222 on the outside of the concave platform 221, and lock the hinge front cover 264 and the mold assembly 1, the locking screw 266 can be screwed into the screw hole 223 of the lower turntable 22, and the small cylinder 2661 at the front end can be embedded in the round hole 2652 of the front movable baffle 265 to reliably lock the front movable baffle 265, in addition, the two sides of the front movable baffle 265 can be embedded in the groove 2621 on the outside of the lower baffle 262 to more reliably fix the mold assembly 1.

[0056] In specific use, the present invention designs a tofu rapid centrifugal dehydration device, which is particularly suitable for rapid centrifugal dehydration of fried tofu blocks. First, the whole tofu block 17 for making small fried tofu is placed in a Figure 4 The bottom of the mold shown in FIG. 1 is covered with a gauze 19, and then the mold cavity 137 is placed as shown in FIG. Figure 2 The upper end surface of the cutting tool 12 shown is pressed with a gauze 18 embedded in the Figure 3 The cover plate slot 114 of the cover plate 11 shown in the figure, and then a set of fixing screws 15 are screwed into the screw holes 112 of the cover plate 11, and embedded into the pin holes 123 of the cutting tool 12 to reliably connect the cover plate 11 and the cutting tool 12, and then the cutting tool 12 is pressed into the mold cavity 137, and the cover plate side convex strip 111 of the cover plate 11 is embedded into the mold side groove 131 of the mold 13, and then the fixing screw 2 16 is screwed into the screw hole 132 of the mold 13, and embedded into the pin hole 113 of the cover plate 11 to reliably connect the cover plate 11 and the mold 12, and then the mold side convex strip 133 of the mold 13 is embedded into the water outlet groove 141 of the drain plate 14, thereby assembling an integral mold assembly 1.

[0057] Then reveal Figure 8The hinge front cover plate 264 shown in the figure, has a narrow side surface of the assembled mold assembly 1 close to the concave platform 221 of the lower turntable 22, with the mold side convex strip 133 facing outward, and is vertically placed in a semi-open slot surrounded by the concave platform 221, the lower side baffle strip 262, and the rear long baffle strip 261, and then the hinge front cover plate 264 is lowered and close to the outer side surface of the mold assembly 1. At the same time, the two side bar holes 2641 of the hinge front cover plate 264 are inserted into the mold side convex strip 133 of the mold assembly 1 to reliably fix the mold assembly 1, and then the two lower convex platforms 2651 under the front movable baffle strip 265 are embedded in the two waisted holes 222 on the outer side of the concave platform 221, and at the same time, the two sides of the front movable baffle strip 265 are respectively embedded in the grooves 2621 on the outer sides of a lower side baffle strip 262 on both sides. At this time, one side of the front movable baffle strip 265 is already close to the outer side surface of the hinge front cover plate 264.

[0058] Then screw the locking screw 266 into the screw hole 223 of the lower turntable 22, and embed the small cylinder 2661 at the front end into the round hole 2652 of the front movable baffle 265 to reliably lock the front movable baffle 265, thereby reliably fixing the hinge front cover plate 264 and the mold assembly 1 inside it.

[0059] like Figure 1 As shown, after the installation of the above-mentioned mold assembly 1 is completed, the reduction motor 10 can be started, so that the motor shaft 101 drives the gear 2 9, and through the meshing transmission gear 1 8, drives the column 3 fixed thereto to rotate, thereby driving the entire turntable assembly 2 carrying a group of mold assemblies 1 to rotate for centrifugal dehydration.

[0060] To ensure smooth operation of the turntable assembly 2, a group of universal ball wheels 5 are evenly installed with the same radius below the lower turntable 22 of the turntable assembly 2. The bottom of the universal ball wheel 5 is tightly attached to the circular base guide rail 61 of the support base 6 to share part of the weight load of the turntable assembly 2.

[0061] When the turntable assembly 2 rotates, the water of the tofu blocks 17 in the inner cavity 137 of each layer of the mold is drained by the centrifugal force along the Figure 6 The path shown by the dotted arrow passes through the gauze 19, flows out from the water seepage hole 134 of the mold 13, flows through the inclined section 142 of the drain plate 14, and then passes through the horizontal interface 136 of the water outlet channel of the mold 13, and finally flows out through the water outlet channel 135 connected to each layer from top to bottom. This special structural design prevents the dehydrated water from each layer from flowing from the tofu block of the previous mold to the tofu block of the next mold, avoiding secondary infiltration. By adjusting the speed of the reduction motor 10, the rate of centrifugal dehydration of the tofu block can be controlled.

[0062] like Figure 1 and Figure 7As shown, in the centrifugal dehydration state, a relatively enclosed space is formed inside the turntable assembly 2 by a set of die assemblies 1, support baffles 24, hollow rotating shafts 21, lower turntables 22, and upper turntables 23. There are several ventilation holes 231 at the position near the center of the top of the upper turntable 23 in this space. Therefore, when the turntable assembly 2 rotates, the fan blades 4 fixedly connected to the hollow rotating shaft 21 will also rotate accordingly, fanning air around. The air can pass through a cluster of ventilation holes 115 on the surface of the cover plate 11 as shown in Figure 3 to accelerate the centrifugal dehydration and cooling effect of the tofu blocks 17 inside the die assembly 1.

[0063] This device can also pass through the hollow inner cavity of the column 3. By connecting a rotary joint at the position of the top cover 25 and externally connecting a gas pipe to pass through the ventilation holes 231 on the top of the upper turntable 23 from top to bottom, cold or hot air can be continuously input into the internal enclosed space of the turntable assembly 2 from the outside to further improve the air-drying and dehydration effect.

[0064] After completing the centrifugal dehydration operation of the tofu blocks, the reduction motor 10 stops. Then, as shown in Figure 8 , unscrew the locking screw 266, pull out and move the front movable stop bar 265 from the waist-shaped hole 222 of the lower turntable 22. Then open the hinge front cover plate 264, take out the entire die assembly 1 from the positioning and fixing card slot mechanism 26 of the turntable assembly 2, place the cover plate 11 flat on the tabletop with the top facing up. Then, as shown in Figure 2 , unscrew the set screw two 16, and then lift the cover plate 11 together with the cutting tool 12 and the first gauze 18 fixed thereto upward to separate from the die 13, and the tofu block 17 in the die cavity 137 can be taken out. For the convenience of cleaning related parts, a set of set screws 15 can be unscrewed to separate the cutting tool 12 from the cover plate 11 and the first gauze 18.
