Description

Technical Field

[0001] This invention relates to the technical field of tofu production and processing, and in particular to a variable pressure compaction device for tofu production and processing. Background Technology

[0002] Tofu production and processing involves multiple steps, from raw material selection to the final product, each crucial in its own way. Among these, pressing the tofu into shape is the most critical step. The purpose of pressing is to remove excess water, making the tofu firmer and improving its texture and taste. By applying pressure, the water is squeezed out of the tofu, increasing its density and resulting in a smoother texture.

[0003] Existing tofu compaction equipment, such as Chinese Patent Publication No. CN216627392U, discloses a tofu production compaction device, including a draining plate and a lifting mechanism located below the draining plate. The lifting mechanism includes a deflecting rod, the lower end of which is connected to a telescopic cylinder via a middle rod. A compaction component is connected to the upper end of the lifting mechanism, including a compaction plate and a top plate. The top plate is fixedly connected to the upper end of the draining plate, and a through groove is formed on the draining plate. A vertical guide rail is fixedly connected to the lower surface of the draining plate, allowing the compaction plate to rise and pass through the through groove. Two connecting columns are fixedly connected to the lower end of the compaction plate, one of which has a pulley connected to one side. Using the compaction plate, tofu can be compacted without pollution, with high compaction efficiency. Different sizes of tofu can be compacted by adjusting the height of the top plate. The structure is reasonable, and the mechanized tofu compaction process is highly stable.

[0004] The above technology mainly uses a pressing plate for compaction, but it does not take into account that the tofu is squeezed out from all sides during the compaction process. Some water will be squeezed out from the top, and this water is often difficult to drain quickly, resulting in backflow and seepage. In addition, when the tofu is not pressed, the equipment is often not dried in time and there are residues on the draining plate that are not cleaned in time, which can cause mold to grow inside.

[0005] Therefore, there is still room for improvement in the existing tofu compaction equipment. Summary of the Invention

[0032] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0033] This application discloses a variable pressure compaction device for tofu production and processing. This device rapidly compacts tofu by squeezing out water through multi-directional drainage, thereby obtaining compacted tofu and greatly improving compaction efficiency.

[0034] Reference Figures 1 to 3 As shown in this embodiment, a variable pressure compaction device for tofu production and processing includes a shell 1, a compaction frame 2, a drainage component 3, a drainage bottom plate 4, a discharge component 5, a sliding track 6, a conveying component 7, a pressing component 8, a locking component 9, a lower pressure plate 10, an electric push rod 11, and a frame 12. The lower end of the shell 1 is supported by a support frame. The compaction frame 2 is slidably disposed inside the shell 1. Drainage components 3 are evenly disposed on the side walls of the compaction frame 2 from top to bottom. The drainage bottom plate 4 is slidably disposed at the bottom of the compaction frame 2. A discharge component 5 is installed in the through groove at the bottom of the 4. The bottom of the discharge component 5 is slidably connected to the sliding rail 6 at the bottom of the compaction frame 2. The conveying component 7 is installed on the side wall of the outer shell 1. The conveying component 7, the drainage bottom plate 4, and the discharge component 5 are used in conjunction. The pressing component 8 is locked in position with the lower pressing plate 10 through the locking component 9. The pressing component 8 in the descending state discharges the water from the upper layer of tofu in the compaction frame 2. The lower pressing plate 10 is connected to the keel frame 12 through the electric push rod 11. The lower end of the keel frame 12 is installed on the upper end of the outer shell 1.

[0035] In the actual compaction process, the compaction frame 2 is pulled out, and the tofu is placed into the compaction frame 2. Then, the compaction frame 2 is pushed back to its original position, and then the drainage bottom plate 4 descends, thereby triggering the discharge component 5 to close the upper opening of the through groove. At the same time, the lower outlet of the conveying component 7 opens, and the lower pressure plate 10 is driven to descend by the electric push rod 11. During the descent, under the action of the locking component 9, the lower pressure plate 10 and the pressing component 8 are in a locked position in the early and middle stages, so that the two descend synchronously. The tofu is compacted by the pressing component 8, thereby squeezing out the water in the tofu from the pressing component 8, the through groove opened by the drainage bottom plate 4, and the drainage component 3 from multiple directions. After the pressing component 8 descends to a certain depth, the locking component 9 is unlocked. At this time, the height of the pressing component 8 remains unchanged, and the lower pressure plate 10 descends, thereby intercepting and retaining the water squeezed into the pressing component 8 to prevent water backflow. Then, it is left to stand and wait, thereby obtaining a complete tofu block. After compaction is completed, the compaction frame 2 is pulled out and the tofu block is taken out.

[0036] Reference Figure 6 As shown, the drainage component 3 improves the drainage effect of the side wall of the compaction frame 2 on the one hand, and ensures ventilation when not compacted, thereby ensuring the dryness of the drainage component 3. The drainage component 3 includes a flip frame 31, the upper end of which is connected to the upper end of the drainage groove 311 opened on the side wall of the compaction frame 2 by a pin. The inside of the flip frame 31 is lined with gauze 32.

[0037] Reference Figure 6 As shown, the drainage trough 311 consists of an inclined trough and a water inlet. The upper inner end of the inclined trough is connected to the water inlet. The inclined trough has a structure that gradually slopes upward from the outside to the inside. The upper end of the flip frame 31 is connected to the upper end of the water inlet through a pin.

[0038] In actual operation, before the tofu is pressed, air is conveyed to the drainage trough 311 through the conveying component 7. Then, the flipping frame 31 containing gauze 32 is blown inward to change the angle. The air conveying method dries the inside of the drainage trough 311 (to prevent mold) and dries the gauze 32 with air. When the tofu is pressed in the subsequent operation, the tofu curd is put into the pressing frame 2. At this time, the air conveying trajectory of the conveying component 7 changes (blowing downward). The flipping frame 31 seals the water inlet under the impact of the tofu curd and its own gravity. The water squeezed out by the tofu curd can enter through the gauze 32 and be discharged from the drainage trough 311.

[0039] Reference Figure 3 , Figure 6 As shown, an electric push rod 13 is connected between the compaction frame 2 and the drainage base plate 4. The electric push rod 13 drives the drainage base plate 4 to rise and fall. An extrusion groove 14 is provided on the inner side wall of the right end of the compaction frame 2. The upper slope of the extrusion groove 14 gradually slopes downward from left to right.

[0040] Reference Figure 4 , Figures 6 to 7 As shown, the water below the tofu curd will be squeezed out through the discharge component 5. After the tofu block is pressed and removed, residual tofu may remain on the discharge component 5. In order to improve the cleaning effect and drying performance of the discharge component 5, this application further improves the structure of the discharge component 5. The discharge component 5 includes a U-shaped frame 51, gauze 52, guide rail 53, sliding column 54, connector 55, and connecting rod 56. The upper outer end of the U-shaped frame 51 is connected to the upper side wall of the through groove through a pin. The inside of the U-shaped frame 51 is lined with gauze 52. The U-shaped frame 51 is arranged symmetrically from left to right. The guide rail 53 is installed on the lower side of the U-shaped frame 51. The sliding column 54 is slidably arranged between the front and rear guide rails 53. The connector 55 is installed between the sliding columns 54. The lower end of the connector 55 is connected to the connecting rod 56. The slider at the lower end of the connecting rod 56 is slidably arranged in the sliding rail 6.

[0041] In actual operation, before the tofu is placed, the drainage base plate 4 is lowered. During the descent, the sliding column 54 slides on the guide rail 53. When the drainage base plate 4 is lowered to the lowest position, the U-shaped frames 51 arranged on the left and right close together, and the gauze 2 52 is arranged horizontally on the left and right, thereby closing the upper opening of the through groove. When pressing the tofu, water is squeezed out from the closed gauze 2 52. After the tofu is formed, the drainage base plate 4 rises back, and the U-shaped frames 51 arranged on the left and right gradually open downwards. When the drainage base plate 4 rises back to the initial height, the U-shaped frames 51 arranged on the left and right drive the gauze 2 52 to tilt downwards, and the residual tofu residue can slide out at an angle. Moreover, the gauze 2 52 is separated, which speeds up the drying effect.

[0042] Reference Figure 3 , Figure 6 As shown, by changing the air delivery trajectory of the conveying component 7 to adapt to the current environment, this application further improves the structure of the conveying component 7. The specific structure is as follows: the conveying component 7 includes an air pump 71 and a partition plate 72. The air pump 71 is installed on the side wall of the outer shell 1 via a base. The side wall interlayer of the outer shell 1 has a conveying cavity 711. The air outlet of the air pump 71 is connected to the conveying cavity 711. The partition plate 72 is horizontally slidably disposed in the movable groove opened in the side wall of the outer shell 1. The outer end of the partition plate 72 is elastically connected to the movable groove.

[0043] Reference Figure 6 As shown, the partition plate 72 has an alignment opening in the middle, and the alignment opening at the initial position is staggered from the conveying cavity 711. At this time, it is in a blocked state, and the inner end of the conveying cavity 711 corresponds to the position of the drainage groove 311.

[0044] Reference Figure 6As shown, the inner end of the partition plate 72 and the L-shaped extrusion member 73 are used in an extrusion fit. The upper end of the extrusion member 73 is connected to the lower end of the compaction frame 2 through a pin. The inner side wall of the extrusion member 73 and the side wall of the drainage base plate 4 are used in an extrusion fit.

[0045] In actual operation, when not pressing, the outlet below the conveying chamber 711 is separated by the partition plate 72. At this time, the air pump 71 delivers air into the drainage trough 311 after passing through the inner end interface of the conveying chamber 711, and finally flushes the gauze 32, thus ensuring the dryness of the conveying chamber 711, the drainage trough 311, and the gauze 32. When pressing is required, the drainage bottom plate 4 descends to squeeze the extrusion member 73. The extrusion member 73 squeezes the partition plate 72 to move outward. When the drainage bottom plate 4 descends to the lowest position, the partition plate 72 moves to the outermost position. At this time, the alignment port on the partition plate 72 is aligned with the conveying chamber 711. At this time, as the water in the bean curd is continuously squeezed out from the water inlet, the air pump 71 delivers air and follows the water squeezed out of the bean curd to be discharged from the lower outlet of the conveying chamber 711.

[0046] Reference Figure 5 , Figure 8 As shown, when the tofu is pressed and squeezed to remove water, some water will be squeezed out from the top. In order to prevent the squeezed water from flowing back, this application uses the cooperation between the pressing component 8 and the locking component 9 to intercept and retain the squeezed water. The specific structure of the pressing component 8 and the locking component 9 in this application is as follows: the pressing component 8 includes a pressing plate 81, and the upper end surface of the pressing plate 81 is evenly provided with an opening groove group 82.

[0047] Reference Figures 8 to 9 As shown, the opening groove group 82 includes a guide groove 821, an extrusion port 822, a connecting port 823, and a linkage groove 824. The upper end face of the pressing plate 81 is provided with the guide groove 821, the extrusion port 822, and the linkage groove 824 from left to right. The guide groove 821 and the extrusion port 822 are connected by the connecting port 823. The connecting port 823 has a structure that gradually slopes downward from right to left. The bottom of the guide groove 821 has a structure that gradually slopes downward from back to front, which is conducive to the smooth discharge of water in the guide groove 821.

[0048] Reference Figure 1 As shown, the front end of the guide channel 821 is provided with a water outlet 825, and the water outlet pipe 826 corresponding to the position of the water outlet 825 is installed at the front end of the compaction frame 2.

[0049] Reference Figures 8 to 9As shown, the locking assembly 9 includes a movable rod 91, a snap-fit ​​component 92, a snap-fit ​​frame 93, a snap-fit ​​groove 94, a pressing block 95, an insert plate 96, and a pressing head 97. The movable rod 91 is horizontally slidably disposed in a sliding groove opened in the lower pressure plate 10, and the right end of the sliding groove is an open structure. L-shaped snap-fit ​​components 92 are evenly installed at the lower end of the movable rod 91. The snap-fit ​​frame 93 is installed at the upper end of the linkage groove 824. A snap-fit ​​groove 94 is opened on the inner wall of the left end of the snap-fit ​​frame 93, and the snap-fit ​​component 92 is horizontally snapped into the snap-fit ​​groove 94 to form a snap-fit ​​tendency. The pressing block 95... 5 is installed at the lower end of the lower pressure plate 10. The snap-fit ​​92 is located in the built-in cavity of the extrusion block 95. The snap-fit ​​92 and the built-in cavity are elastically connected. Under the elastic action, the snap-fit ​​92 always maintains the tendency to move to the left. The insert plate 96 is horizontally slidably set at the lower end of the linkage groove 824. An extrusion head 97 is installed on the upper right side of the insert plate 96. The extrusion head 97 and the lower inclined surface of the extrusion block 95 are used for extrusion. The extrusion head 97 and the linkage groove 824 are elastically connected. Under the elastic action, the extrusion head 97 always maintains the tendency to move to the right.

[0050] In actual operation, after the tofu curd is placed into the pressing frame 2, the electric push rod 11 drives the lower pressing plate 10 and the position-locking pressing component 8 to descend synchronously. The pressing plate 81 compacts the tofu curd, and the water in the tofu curd is squeezed out from the extrusion port 822 and flows into the guide channel 821 through the connection port 823. Since the bottom of the guide channel 821 is inclined, the squeezed water is transported to the front of the guide channel 821 under the action of its inclined structure, and then enters the water outlet pipe 826 after passing through the water outlet 825 and is discharged. As the pressing plate 81 continues to descend, the water in the tofu curd is continuously squeezed out. At the right end of the movable rod 91 in the locking component 9, the water is... When the pressure plate is in the position of the compression groove 14, under the action of elasticity, the movable rod 91 drives the locking piece 92 to move to the right. At this time, the locking piece 92 no longer forms a locking state with the locking groove 94. The height of the pressing plate 81 remains unchanged under the compression of the upper surface of the tofu. However, the lower pressure plate 10 continues to descend under the drive of the electric push rod 11. The compression block 95 descends synchronously. The descending compression block 95 compresses the compression head 97, causing the insert plate 96 to move to the left, thereby blocking the lower opening of the extrusion port 822. This keeps the water in the extrusion port 822 inside the extrusion port 822, preventing water from flowing back. Then, the current state is maintained and the tofu is left to stand, allowing the tofu to form.

[0051] Working principle:

[0052] Step 1: Pull out the pressing frame 2, put the tofu into the pressing frame 2, and push the pressing frame 2 back to its original position;

[0053] Step 2: The drainage base plate 4 descends, and the sliding column 54 slides on the guide rail 53. When the drainage base plate 4 descends to the lowest position, the U-shaped frame 51 arranged on the left and right closes, and the gauze 2 52 is arranged horizontally on the left and right, thereby closing the upper opening of the through groove. At the same time, under the action of the squeezing force, the partition plate 72 is squeezed to align its alignment port with the position of the conveying chamber 711, and the lower outlet position of the conveying chamber 711 opens.

[0054] Step 3: The electric push rod 11 drives the lower pressure plate 10 and the position-locking pressing component 8 to descend synchronously. The pressing plate 81 compacts the tofu curd. The water in the tofu curd is squeezed out from the extrusion port 822 and flows into the guide groove 821 through the connection port 823. Finally, it enters the water outlet pipe 826 after passing through the water outlet 825 and is discharged.

[0055] Step 4: As the pressing plate 81 continues to descend, the water in the tofu is continuously squeezed out. When the right end of the movable rod 91 in the locking component 9 is aligned with the position of the extrusion groove 14, under the action of elasticity, the movable rod 91 drives the snap-fit ​​piece 92 to move to the right. At this time, the snap-fit ​​piece 92 no longer forms a snap-fit ​​state with the snap-fit ​​groove 94, and the position between the lower pressing plate 10 and the pressing plate 81 is unlocked. The height of the pressing plate 81 remains unchanged under the pressure of the upper surface of the tofu. The lower pressing plate 10 continues to descend under the drive of the electric push rod 11, and the extrusion block 95 descends synchronously. The descending extrusion block 95 presses the extrusion head 97, causing the insert plate 96 to move to the left, thereby intercepting and blocking the lower opening position of the extrusion port 822, and thus keeping the water in the extrusion port 822 inside the extrusion port 822.

[0056] Step 5: Let it stand in its current state until the tofu sets.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
