Description

Technical Field

[0001] This utility model relates to the field of soybean product processing technology, and in particular to a dewatering device for tofu processing. Background Technology

[0002] Tofu, a traditional Chinese food with a long history, holds a significant place in culinary culture due to its rich nutritional value and delicate texture. It is typically made from high-protein legumes such as soybeans, black beans, and peanuts, and can be enjoyed year-round, regardless of season. The tofu-making process mainly involves two core steps: soy milk preparation and coagulation. The former involves soaking and grinding carefully selected soybeans to extract pure and smooth soy milk; the latter uses heat and a specific coagulant to transform the soy milk into a moist, pliable gel – tofu. Tofu is not only rich in many essential trace elements but also contains high-quality plant protein, earning it the nickname "plant-based meat." With a digestibility rate exceeding 95%, it is an ideal choice for a healthy diet. This exceptional nutritional value makes tofu popular among consumers of all ages, driving continuous innovation and development in tofu-making techniques.

[0003] However, in the traditional tofu processing, especially the crucial step of squeezing out the water, manual operation is often relied upon. This step is not only labor-intensive, but it is also difficult to ensure that the tofu is subjected to uniform force during the squeezing process. If not careful, the tofu may be damaged due to excessive squeezing, which seriously affects the final quality of the product. In addition, manual squeezing is inefficient and costly, which makes it difficult to meet the needs of modern industrial production. Utility Model Content

[0004] This utility model discloses a water-squeezing device for tofu processing, which solves the problems of high labor intensity, low efficiency, high cost, and easy breakage of tofu caused by the traditional method of manually squeezing water in tofu processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A dewatering device for tofu processing includes a horizontally arranged base plate, a horizontally movable lifting plate above the base plate, and a lifting assembly on the base plate for driving the lifting plate to move up and down. A support sleeve with both its top and bottom surfaces open is fixed at the center of the lifting plate, and the top and bottom ends of the support sleeve penetrate the top and bottom surfaces of the lifting plate and extend outside the lifting plate, respectively. A drain basket is detachably connected inside the support sleeve, and the bottom surface of the drain basket has several drain holes evenly distributed. A support frame is fixed at the edge of the base plate, and a horizontal pressure plate is movably mounted on the support frame, with the pressure plate located directly above the drain basket. A first driving assembly on the support frame is used to drive the pressure plate to move up and down a short distance back and forth. A water collection box is also provided on the top surface of the base plate, located directly below the support sleeve.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The first drive assembly first positions the pressure plate at the top. The tofu to be squeezed is placed in the drain basket, which is then placed on the support sleeve. Next, the lifting assembly drives the lifting plate upwards, moving the entire drain basket upwards until the top surface of the tofu in the basket is in contact with the bottom surface of the pressure plate. Then, the first drive assembly drives the pressure plate to move back and forth a short distance, squeezing out the water from the tofu through high-frequency, short-distance compression without causing the tofu to break. The squeezed water drains through the drain holes on the bottom of the drain basket and falls into a collection box through the support sleeve for collection. This invention is highly automated and practical. By setting up a base plate, lifting assembly, lifting plate, drain basket, support frame, pressure plate, and first drive assembly, it can automatically squeeze water out of tofu. The high-frequency, short-distance squeezing method effectively removes excess water from the tofu without causing breakage due to excessive compression, thus ensuring the quality of the final product.

[0016] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model provides a dewatering device for tofu processing, including a horizontally arranged base plate 1, a horizontally movably mounted lifting plate 2 above the base plate 1, and a lifting assembly for driving the lifting plate 2 to move up and down on the base plate 1; a support sleeve 3 with both its top and bottom surfaces open is fixed at the center of the lifting plate 2, and the top and bottom ends of the support sleeve 3 penetrate the top and bottom surfaces of the lifting plate 2 respectively and extend outside the lifting plate 2; a drain basket 4 is detachably connected inside the support sleeve 3, and a plurality of drain holes 41 are evenly opened on the bottom surface of the drain basket 4; a support frame 5 is fixed at the edge of the base plate 1, and a horizontal pressure plate 51 is movably mounted on the support frame 5, and the pressure plate 51 is located directly above the drain basket 4; a first driving assembly for driving the pressure plate 51 to move up and down a short distance back and forth is provided on the support frame 5; a water collection box 7 is also provided on the top surface of the base plate 1, located directly below the support sleeve 3.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the first drive assembly includes two vertical slide rods 52 that are slidably connected to the support frame 5. The two slide rods 52 are symmetrically arranged, and the bottom ends of the two slide rods 52 pass through the support frame 5 and extend outside the support frame 5. Two sliding grooves are opened in the support frame 5 for the corresponding slide rods 52 to move. Springs 53 are sleeved on the surface of the two slide rods 52. Vertical racks 54 are fixed to the bottom ends of the two slide rods 52, and the serrated surfaces of the two racks 54 are arranged opposite each other. The bottom ends of the two racks 54 are fixedly connected to the top surface of the pressure plate 51. Two half gears 55 are rotatably connected to the support frame 5, which respectively mesh with the serrated surfaces of the corresponding racks 54. The support frame 5 is provided with a second drive assembly for driving the two half gears 55 to rotate simultaneously in different directions. Specifically, the half gear 55 is existing technology, referring to a gear with only half a circle of serrations. By using the second drive component to drive the left half gear 55 to rotate clockwise while simultaneously driving the right half gear 55 to rotate counterclockwise, it is possible to simultaneously control the upward movement of the two racks 54, thereby driving the pressure plate 51 to move upward. At this time, both slide rods 52 will squeeze the corresponding springs 53 and move upward into the corresponding slide grooves in the support frame 5 (slide grooves are not shown in the diagram). When both half gears 55 rotate to the position where there are no teeth on the other half circle, both slide rods 52 will move downward under the elastic force of the corresponding springs 53, thereby driving the pressure plate 51 to move downward, thus realizing a high-frequency, short-distance squeezing method.

[0019] like Figure 2 and Figure 3 As shown, the second drive assembly includes two symmetrically and horizontally rotatably connected rotating shafts 6 on the support frame 5. One end of each rotating shaft 6 is fixedly connected to the center of a corresponding half-gear 55. The ends of both rotating shafts 6 away from the corresponding half-gear 55 pass through the support frame 5 and extend outside the support frame 5. A horizontal motor 61 is also provided on the support frame 5. The output end of the motor 61 is fixedly connected to the end of one of the rotating shafts 6 located outside the support frame 5. Gears 62 are fixed to the surfaces of the ends of both rotating shafts 6 located outside the support frame 5, and the two gears 62 mesh with each other. When the motor 61 is started, the output end of the motor 61 drives the rotating shaft 6 connected to it to rotate, which in turn drives the other rotating shaft 6 to rotate simultaneously in the opposite direction through the two meshing gears 62. Thus, the pressure plate 51 achieves short-distance reciprocating motion through the half-gear 55, rack 54, slide bar 52, and spring 53. Through this high-frequency, short-distance squeezing method, excess water in the tofu can be squeezed out without causing the tofu to break due to excessive squeezing, effectively ensuring the quality of the final product.

[0020] like Figure 1 and Figure 6As shown, the lifting assembly includes four vertically fixed cylinders 21, each fixed at one of the four corners of the top surface of the base plate 1. Each of the four fixed cylinders 21 has a vertically slidable movable rod 22. The top ends of the four movable rods 22 are fixedly connected to the four corners of the bottom surface of the lifting plate 2. Vertical automatic push rods 23 are fixed to both sides of the top surface of the base plate 1, and the output ends of the two automatic push rods 23 are fixedly connected to the bottom surface of the lifting plate 2. When the automatic push rods 23 are activated, their output ends drive the lifting plate to move up and down, thereby moving the drain basket 4 up and down to squeeze water from the tofu. The movable rods 22 and the fixed cylinders 21 provide support and guidance for the lifting plate 2 without hindering its vertical movement.

[0021] like Figure 4 As shown, the top edge of the drain basket 4 extends outward, and the top of the support sleeve 3 and the extended end of the drain basket 4 are detachably connected by a screw 42. The screw 42 allows for quick fixing and disassembly of the drain basket 4, and also prevents the drain basket 4 from shifting during the squeezing process, thus avoiding unnecessary errors in the squeezing operation.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the extended end of the drain basket 4 is also symmetrically fixed with two handles 43, and both handles 43 are horizontally positioned. The handles 43 facilitate workers to pick up and remove the drain basket 4 to load and unload the tofu.

[0023] In use, first start the motor 61. The output of the motor 61 drives the rotating shaft 6 connected to it to rotate, which in turn drives another rotating shaft 6 to rotate in the opposite direction through two meshing gears 62. This causes the left half gear 55 to rotate clockwise and the right half gear 55 to rotate counterclockwise, thus controlling the two racks 54 to move upward, thereby moving the pressure plate 51 upward and placing the pressure plate 51 at the top. At this time, both slide rods 52 will compress the corresponding springs 53 and move upward into the corresponding grooves in the support frame 5. Next, place the tofu to be squeezed into the drain basket 4 and place the drain basket 4 on the support sleeve 3. Then, use the automatic push rod 23 to drive the lifting plate 2 upward, which will move the entire drain basket 4 upward, allowing the tofu to be squeezed out. The top surface of the tofu in the water basket 4 is in contact with the bottom surface of the pressure plate 51. Then, the motor 61 is started again, causing the two half gears 55 to continue rotating in the previous direction. When both half gears 55 have rotated to the position where there are no teeth in the other half of the rotation, the two slide rods 52 will move down under the elastic force of the corresponding springs 53, thereby driving the pressure plate 51 to move down. The motor 61 is kept running to realize the short-distance reciprocating motion of the pressure plate 51. Through this high-frequency short-distance squeezing method, excess water in the tofu can be squeezed out without causing the tofu to break due to excessive squeezing, which effectively ensures the quality of the final product. The squeezed water is drained out through the drain hole 41 on the bottom surface of the drain basket 4 and falls into the water collection box 7 through the support sleeve 3 for collection and treatment.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
