Description

Technical Field

[0001] This invention relates to the technical field of tofu processing equipment, and more particularly to a tofu forming device. Background Technology

[0002] Baojiang tofu is made from gypsum tofu, with an additional step of soaking in baking soda water. To make it, fresh tofu is pressed again, sliced, and arranged to prevent sticking; it is then soaked in water with baking soda for 6 to 8 hours. After soaking, the tofu is removed, rinsed thoroughly with water, and allowed to air dry. Once the moisture has evaporated, it becomes baojiang tofu.

[0003] The processing of tofu with a protective coating requires molding and pressing. Typically, a layer of tofu cloth is laid in the molding mold, and then the unshaped raw material is placed into the molding frame and spread evenly. It is then shaped under the pressure of a press. During the molding process, the moisture in the raw material is squeezed into the molding mold under pressure. The mold usually has drainage holes at the bottom, allowing some water to drain out. However, because the molded tofu is firm and wrapped in tofu cloth, a significant amount of water remains trapped inside the mold, both at the top and bottom, and between the tofu and the mold. When the tofu is poured directly from the mold onto a tofu board for drying, a large amount of water spills into the work environment, affecting hygiene and reducing drying efficiency due to the untimely drainage. Summary of the Invention

[0004] The purpose of this invention is to provide a tofu-forming device that can effectively absorb the moisture that seeps out of the raw material after it has been pressed and formed, thereby reducing the moisture content inside the forming device and minimizing water spillage into the surrounding environment when the tofu is removed from the forming device. It can also reduce the amount of water adhering to the finished tofu and improve drying efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A tofu-forming device includes a forming frame, a water-collecting frame elastically disposed at the bottom of the forming frame, and an elastic airbag disposed between the water-collecting frame and the forming frame. The airbag communicates with the interior of the forming frame through a water-collecting hole at the bottom of the forming frame. A forming grid plate is disposed inside the forming frame, and a support frame is placed at the top of the forming grid plate. A shaping groove corresponding to the forming grid plate is disposed at the bottom of the support frame. An elastic airbag is conductively disposed at the top of the support frame, and a support frame is conductively connected to the top of the airbag. The support frame and the support frame are elastically connected.

[0007] Preferably, the molding frame and the water collection frame are connected by a first spring, the bottom of the molding frame is provided with a first guide rod, the first guide rod is located inside the first spring, and the water collection frame is provided with a first guide hole for the first guide rod to move through.

[0008] Preferably, the carrier frame and the support frame are connected by a second spring, and a second guide rod is coaxially arranged inside the second spring. The second guide rod is arranged on the carrier frame and movably passes through a second guide hole, which is opened on the support frame.

[0009] Preferably, the molding frame is provided with receiving grooves on both sides, and the molding grid plate is provided with handles on both sides. The handles are located in the receiving grooves, and their ends extend out from the receiving grooves.

[0010] Preferably, at least one side wall of the water collection frame and the support frame is provided with an exhaust hole that communicates with its interior, and a sealing plate is elastically hinged to the outside of the exhaust hole.

[0011] Preferably, a rubber sealing plug is provided on one side of the water collection frame.

[0012] Preferably, a cover plate is provided at the top of the support frame.

[0013] Preferably, the support frame is provided with handles on both sides.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: By elastically connecting the water collection frame and the air bladder at the bottom of the forming frame, the air bladder can be compressed and vented when the raw material is squeezed to form the tofu. At this time, the internal pressure of the air bladder is less than the external pressure. After the pressurization is completed, under the external pressure and the elastic restoring force of the forming frame and the water collection frame, the water flow at the bottom of the formed tofu and part of the gap between the tofu and the forming frame is drawn into the water collection frame, reducing the water content of the tofu. Similarly, the top support frame and the air bladder draw the water flow at the top of the tofu and part of the gap between the tofu and the forming frame into the support frame. This reduces the amount of water covering the surface of the formed tofu, avoids a large amount of water spillage during the process of transferring and pouring the tofu onto the tofu board, and also improves the drying efficiency of the tofu.

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 4 As shown, the tofu-forming device of the present invention includes a forming frame 1, a water-collecting frame 2 elastically disposed at the bottom of the forming frame 1, and an elastic airbag 3 disposed between the water-collecting frame 2 and the forming frame 1. The airbag 3 is made of rubber, with its bottom end communicating with the interior of the water-collecting frame 2 and its top end communicating with the interior of the forming frame 1. The bottom of the forming frame 1 is a flat plate structure with densely spaced water-collecting holes 4. The top end of the airbag 3 communicates with the interior of the forming frame 1 through the water-collecting holes 4. A forming grid plate 5 is disposed inside the forming frame 1. The forming grid plate 5 is used to shape the tofu, and its specific internal shape can be flexibly customized according to requirements. The trough is rectangular in cross-section, with the grooving plate 5 extending through it so that it can communicate with the airbag 3 below through the water collection hole 4. A support frame 6 is placed at the top of the grooving plate 5, and a shaping groove corresponding to the grooving plate 5 is provided at the bottom of the support frame 6 so that the grooving plate 5 and the shaping groove can cooperate to form a shaping space to achieve the forming process of tofu. A through hole is provided in the shaping groove, and the top of the support frame 6 is connected to the elastic airbag 3 through the through hole. The top of the airbag 3 is connected to the support frame 7, and a cavity is formed inside the support frame 7 for temporary water storage. In addition, the support frame 7 and the support frame 6 are elastically connected. During operation, the forming grid is first placed inside the forming frame 1, and then a layer of tofu cloth is placed on the forming grid. The raw material is then poured onto the forming grid and spread evenly. The remaining part of the tofu cloth is folded over the spread material to wrap it. Finally, the supporting frame 6 is placed on the tofu cloth, and the specified pressure is applied using a press. When the press applies pressure, the support frame 7 and the supporting frame 6, as well as the forming frame 1 and the water collection frame 2, are elastically connected. This causes the airbag 3 to be pressed down, resulting in the release of gas from inside the airbag 3 and a reduction in internal pressure. After pressurization, the airbag 3 returns to its original position due to the combined effect of the pressure difference and elastic restoring force. The resulting suction then draws water from the forming frame 1, reducing the amount of water adhering to the surface of the formed tofu. This provides favorable conditions for the subsequent pouring and drying of the finished tofu, preventing excessive water from spilling into the surrounding environment during pouring and improving drying efficiency.

[0021] Specifically, in this embodiment, the forming frame 1 and the water collecting frame 2 are connected by a first spring 8, and a first guide rod 9 is provided at the bottom of the forming frame 1. The first guide rod 9 is coaxially located inside the first spring 8, and a first guide hole is provided on the water collecting frame 2 for the first guide rod 9 to pass through. In addition, the bearing frame 6 and the support frame 7 are connected by a second spring 10. A second guide rod 11 is coaxially provided inside the second spring 10. The second guide rod 11 is set on the bearing frame 6 and passes through the second guide hole, which is opened at the four corners of the support frame 7. The elastic connection between the forming frame 1 and the water collecting frame 2, and between the support frame 7 and the bearing frame 6, can effectively buffer the force on the airbag 3 when the press applies pressure, preventing the airbag 3 from frequently being in the extreme deformation state, which would greatly reduce its service life; at the same time, it can also drive the airbag 3 to reset, so as to achieve smooth water absorption.

[0022] Furthermore, both sides of the forming frame 1 are provided with vertically oriented receiving grooves 12, and both sides of the forming grid plate 5 are provided with handles 13. The handles 13 are located inside the receiving grooves 12, and their ends extend out from the receiving grooves 12, making it convenient to remove the forming grid plate 5 from the forming frame 1 after the tofu has been formed. At the same time, since the forming grid plate 5 has a structure that runs through the top and bottom, only the forming grid plate 5 needs to be removed to lift and remove the formed tofu. This also further reduces the amount of water adhering to the bottom of the forming grid plate 5, allowing the water to remain in the forming frame 1, thus improving the practicality of the invention. In addition, in this embodiment, both sides of the support frame 7 are provided with handles 17 to facilitate the picking and putting-away operation of the support frame 7.

[0023] Furthermore, at least one side wall of the water collection frame 2 and the support frame 7 is provided with an exhaust hole that communicates with its interior. A sealing plate 14 is elastically hinged to the side wall of the water collection frame 2 or the support frame 7 outside the exhaust hole. The exhaust hole allows the gas inside the airbag 3 to be discharged through the exhaust hole when the airbag 3 is pressurized, reducing the amount of gas entering the forming frame 1 when the airbag 3 is pressurized, so as not to adversely affect the pressing and forming of the tofu. The elastic hinge of the sealing plate 14 ensures that it unfolds under the thrust of the gas when the airbag 3 is discharged, and seals the exhaust hole under the elastic restoring force when the gas is discharged. The sealing plate 14 is hinged to the outside of the side wall of the water collection frame 2 and the support frame 7, which ensures that when the airbag 3 resumes to absorb water, the sealing plate 14 is always in a sealed state for the exhaust hole, avoiding insufficient suction due to air leakage.

[0024] Furthermore, in this embodiment, a rubber sealing plug 15 is provided on one side of the water collection frame 2. The rubber sealing plug 15 is movable to the drainage groove opened on one side of the water collection frame 2, and the water inside the water collection frame 2 can be quickly discharged by removing the rubber sealing plug 15. In addition, a cover plate 16 is preferably provided at the top of the support frame 7. The cover plate 16 is slidably provided at the top of the support frame 7, so that the water inside the support frame 7 can be discharged by opening the cover plate 16.

[0025] In use, this invention involves first placing the forming grid inside the forming frame 1, then laying a layer of tofu cloth on the grid. The raw material is then poured onto the grid and spread evenly. The remaining portion of the tofu cloth is folded over the spread material to wrap it. Finally, the supporting frame 6 is placed on the tofu cloth, and a press is used to apply the specified pressure. During pressurization, the support frame 7, the supporting frame 6, the forming frame 1, and the water collection frame 2 are all elastically connected. This causes the airbag 3 to be compressed, releasing the gas inside and reducing its internal pressure. After pressurization, the airbag 3 returns to its original position due to the combined effect of the pressure difference and elastic recovery force. The resulting suction then draws water from the forming frame 1, reducing the amount of water adhering to the surface of the formed tofu. This provides favorable conditions for the subsequent drying of the finished tofu, preventing excessive water spillage into the surrounding environment during pouring and improving drying efficiency. After the tofu is removed, the water absorbed into the water collection frame 2 and the support frame 7 is drained. The structure is simple and the operation is convenient.
