Description

Technical Field

[0001] This utility model relates to the field of soybean product processing technology, specifically a soybean product pressing and molding mold. Background Technology

[0002] In the tofu production and processing industry, the pressing process is the core step that determines the quality of tofu. After the prepared tofu curd is placed into a mold, the pressing time and pressure must be precisely controlled to effectively remove excess water, thereby shaping the tofu to achieve the ideal quality, taste, and appearance. However, current tofu pressing technology still has many problems that urgently need to be solved.

[0003] The utility model patent with announcement number CN221307194U discloses a soybean product pressing and molding device. Its main structure includes a base plate, a support rod, a top plate and a cylinder. The molding die is composed of a pressing component and a water outlet component connected by a connecting assembly. The pressing component is driven by the cylinder to achieve the pressing function.

[0004] However, this existing technology has some shortcomings in its structural design and pressing method. First, the device can only apply pressure to the soy product from a single direction using a top cylinder, resulting in uneven stress distribution during the pressing process. This not only leads to significant differences in the internal density of the tofu but also easily causes irregular shapes in the formed tofu, seriously affecting product quality and yield, making it difficult to meet the market's stringent requirements for high-quality tofu products. Second, there are deficiencies in the demolding process. Due to the lack of a convenient demolding structure design, operators need to use additional tools or adopt complex operating procedures to demold the tofu after pressing. This process is not only time-consuming and labor-intensive, significantly increasing labor and time costs, but also highly susceptible to damage to the tofu due to improper operation, directly reducing production efficiency and further increasing production costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides the following technical solution: A bean product pressing and molding mold, comprising a supporting part, an upper pressure plate, a lower pressure plate, an upper transmission part, and a lower transmission part; the supporting part is slidably disposed on a support frame, and the supporting part includes a supporting outer shell slidably disposed on the support frame, with a supporting return spring disposed between the supporting outer shell and the support frame; the upper pressure plate is slidably disposed within the supporting outer shell, and the upper pressure plate is detachably disposed on the upper transmission part; the lower pressure plate is slidably disposed within the supporting outer shell, and the lower pressure plate is detachably disposed on the lower transmission part; the upper transmission part... The system includes an upper transmission mounting ring detachably fitted to the upper pressure plate, which is slidably mounted on the upper transmission plate. An upper transmission return spring is provided between the upper transmission plate and the upper transmission mounting ring. An upper transmission handle is rotatably mounted on the upper transmission plate and is threadedly fitted to the upper transmission shaft. The lower transmission part includes a lower transmission mounting ring detachably fitted to the lower pressure plate, which is slidably mounted on the lower transmission mounting ring. A lower transmission return spring is provided between the lower transmission mounting ring and the lower transmission plate. A lower transmission handle is rotatably mounted on the lower transmission plate and is threadedly fitted to the support frame.

[0006] Furthermore, the upper drive shaft is rotatably mounted on the support frame, one end of the upper drive shaft is fixedly mounted with an upper drive adjustment handle, and the other end of the upper drive shaft is fixedly mounted with an upper drive connecting rod. The other end of the upper drive connecting rod is mounted on the support frame via an upper drive adjustment and reset spring.

[0007] Furthermore, the upper pressure plate is engaged with the through hole on the upper transmission mounting ring by insertion, and the upper pressure plate is detachably mounted on the upper transmission mounting ring by the upper transmission mounting nut.

[0008] Furthermore, the lower pressure plate is engaged with the through hole on the lower transmission mounting ring by an insertion connection, and the lower pressure plate is detachably mounted on the lower transmission mounting ring by a lower transmission mounting nut.

[0009] Furthermore, both the upper and lower pressure plates are provided with filter holes for liquid flow.

[0010] Furthermore, the bottom of the support frame is provided with a collection pool for collecting liquid, and the bottom of the collection pool is provided with a conduit for cleaning the liquid.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. Uniform pressure distribution improves product quality; this device supports two pressing methods through the coordinated design of the upper and lower transmission units. Operators can choose to press down the upper platen alone, or have the upper and lower platens press simultaneously. Especially when the upper and lower platens press simultaneously, the soy products receive more uniform pressure within the outer shell, better filling the mold cavity and forming a regular, compliant shape. This significantly improves the internal density consistency of the tofu, enhances product quality and yield, and meets market demand for high-quality soy products.

[0013] 2. Optimized demolding structure for improved production efficiency: This device achieves convenient and rapid demolding through the sliding fit between the bearing part and the support frame, and the setting of the bearing return spring. After pressing, the operator manually presses down the bearing shell, the bearing return spring retracts, the bearing shell moves down, and the formed bean product remains on the lower pressing plate. Demolding can be completed without complicated operations and additional tools, greatly reducing labor and time costs, reducing the tofu breakage rate, significantly improving production efficiency, and effectively controlling production costs.

[0014] 3. Flexible extrusion design ensures product texture: The application of upper and lower drive return springs allows the upper and lower pressure plates to gently extrude the soy products during the pressing process. This design ensures a tight fit between the pressure plates and the soy products, avoiding structural damage caused by rigid extrusion. While effectively removing excess moisture, it better preserves the internal structure and texture of the soy products, improving their edible quality. Attached Figure Description

[0028] like Figures 1 to 7 As shown, the upper transmission unit 1 includes an upper transmission adjusting handle 101, an upper transmission shaft 102, an upper transmission handle 103, an upper transmission plate 104, an upper transmission mounting ring 105, an upper transmission mounting nut 106, an upper transmission return spring 107, an upper transmission adjusting return spring 108, and an upper transmission connecting rod 109. The upper transmission mounting ring 105 is disc-shaped, and two guide rods are provided on the top of the upper transmission mounting ring 105. The upper transmission plate 104 is slidably mounted on the guide rods. An upper transmission return spring 107 is provided between the upper transmission plate 104 and the upper transmission mounting ring 105, and one end of the upper transmission return spring 107 is fixedly mounted on the upper transmission plate 104. On the upper transmission plate 104, the other end of the upper transmission return spring 107 is fixedly mounted on the upper transmission mounting ring 105. The upper transmission handle 103 is rotatably mounted on the upper transmission plate 104. The upper transmission handle 103 is threadedly engaged with the upper transmission shaft 102.

[0029] like Figures 1 to 7 As shown, the lower transmission unit 2 includes a lower transmission mounting ring 201, a lower transmission return spring 202, a lower transmission plate 203, a lower transmission handle 204, and a lower transmission mounting nut 205.

The lower transmission handle 204 is rotatably mounted on the lower transmission plate 203. The lower transmission handle 204 is threadedly engaged with the support frame 6.

[0030] like Figure 7 As shown, the bottom of the support frame 6 is provided with a collection tank for collecting liquid, and a conduit is provided at the bottom of the collection tank for cleaning the liquid.

[0031] like Figures 1 to 7 As shown, the present invention discloses a bean product pressing mold. Its working principle is as follows: When pressing bean products, the operator manually moves the upper transmission adjustment handle 101. The rotation of the upper transmission adjustment handle 101 drives the upper transmission shaft 102 to rotate. The rotation of the upper transmission shaft 102 in turn drives the upper transmission handle 103, upper transmission plate 104, upper transmission return spring 107, upper transmission mounting nut 106, upper transmission mounting ring 105, and upper pressure plate 3, which are set on the upper transmission shaft 102, to rotate together with the upper transmission shaft 102 as the center. This causes the upper pressure plate 3 to leave the opening at the top of the bearing shell 501, leaving the opening position open for the operator to place the bean product into the bearing shell 501. After the operator places the bean product into the bearing shell 501, the upper transmission adjustment return spring 108 causes the upper transmission shaft 102 and the upper transmission handle 103, upper transmission plate 104, upper transmission return spring 107, upper transmission mounting nut 106, upper transmission mounting ring 105, and upper pressure plate 3 set on it to return to their initial positions.

[0032] When pressing and molding the bean products inside the outer shell 501, the operator first manually rotates the lower transmission handle 204. The lower transmission handle 204 moves through the lower transmission plate 203 and the lower transmission return spring 202, which in turn drives the lower transmission mounting ring 201 and the lower pressure plate 4 to move, so that the lower pressure plate 4 moves into the outer shell 501, and the lower pressure plate 4 and the outer shell 501 form a mold.

[0033] The specific operation of pressing method one is as follows: The operator manually rotates the upper transmission handle 103. The rotation of the upper transmission handle 103 drives the upper transmission plate 104 to move. The movement of the upper transmission plate 104, through the upper transmission return spring 107, drives the upper transmission mounting ring 105 and the upper pressure plate 3 set on the upper transmission mounting ring 105 to move towards the bean product inside the supporting shell 501. At this time, the upper pressure plate 3, which continues to move towards the bean product, squeezes the bean product located in the lower pressure plate 4 and the supporting shell 501. During this process, the upper transmission return spring 107 ensures that the upper pressure plate 3 is in close contact with the bean product. The upper pressure plate 3 gently squeezes the bean product, and the water in the bean product flows out through the water filter holes on the upper pressure plate 3 and the lower pressure plate 4, so that the bean product is finally pressed into shape. After pressing, the upper transmission handle 103 is turned to reset the upper transmission handle 103. The operator manually presses down the bearing shell 501. At this time, the bearing reset spring 502 contracts, and the bearing shell 501 moves to the bottom point. The formed bean product remains on the lower pressure plate 4, completing the rapid demolding. After demolding, the bearing shell 501 is released, and the bearing shell 501 resets under the action of the bearing reset spring 502.

[0034] The specific operation of pressing method two is as follows: the operator manually rotates the upper transmission handle 103 while simultaneously rotating the lower transmission handle 204. The rotation of the upper transmission handle 103 drives the upper transmission plate 104 to move. The movement of the upper transmission plate 104, through the upper transmission return spring 107, drives the upper transmission mounting ring 105 and the upper pressure plate 3 set on the upper transmission mounting ring 105 to move towards the bean product inside the bearing shell 501. At the same time, the rotation of the lower transmission handle 204 drives the lower transmission plate 203 to move. The movement of the lower transmission plate 203, through the lower transmission return spring 202, drives the lower transmission mounting ring 201 and the lower pressure plate 4 to move towards the bean product inside the bearing shell 501. This allows the upper pressure plate 3 and the lower pressure plate 4 to simultaneously squeeze the bean product inside the bearing shell 501, so that the bean product receives a more uniform pressure distribution inside the bearing shell 501. This helps the bean product to better fill the cavity inside the bearing shell 501 and form a more regular and compliant shape. The upper pressure plate 3 and lower pressure plate 4, which continuously move towards the bean product, continuously squeeze the bean product inside the supporting shell 501. During this process, the upper drive return spring 107 keeps the upper pressure plate 3 in close contact with the bean product, and the lower drive return spring 202 keeps the lower pressure plate 4 in close contact with the bean product. This results in the upper pressure plate 3 and lower pressure plate 4 performing flexible squeezing on the bean product. Water in the bean product flows out through the water filter holes on the upper pressure plate 3 and lower pressure plate 4, allowing the bean product to be finally pressed and shaped. Because pressure is applied simultaneously at both ends of the supporting shell 501, the bean product experiences a greater resultant force, and the pressing process can be completed faster, improving production efficiency. After pressing, the upper drive handle 103 is rotated to reset the upper drive handle 103. The operator manually presses down the supporting shell 501. At this time, the supporting return spring 502 contracts, and the supporting shell 501 moves to its lowest point. The shaped bean product remains on the lower pressure plate 4, completing rapid demolding. After demolding, the supporting shell 501 is released, and the supporting shell 501 returns to its original position under the action of the supporting return spring 502.

[0035] During the pressing process, the water in the soy products flows into the collection pool at the bottom of the support frame 6 under the action of gravity, and is eventually discharged through the conduit.
