Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution for a tofu skin processing and pressing device: a tofu skin processing and pressing device includes: a base 1, a bracket 2 fixedly installed on the base 1, two symmetrically distributed sliding grooves 3 fixedly installed on the top of the base 1, a forming groove 4 provided at the upper end of the base 1, the two ends of the forming groove 4 being slidably arranged in the sliding grooves 3 on both sides, and a pressure plate 5 provided in the bracket 2, the pressure plate 5 being arranged above the forming groove 4. A drive mechanism is installed on the bracket 2. The drive mechanism is connected to the pressure plate 5. The drive mechanism is used to move the pressure plate 5 into the forming groove 4. Multiple drainage ports 6 are evenly distributed in the forming groove 4. A filter cloth 7 is installed in the forming groove 4. The filter cloth 7 is fixedly connected to the inner side of the forming groove 4. The bottom of the filter cloth 7 is in contact with the bottom surface of the forming groove 4. The drive mechanism includes four guide sleeves 8 distributed at four corners. The upper end of the guide sleeve 8 is fixedly connected to the bracket 2. A sliding guide rod 9 is inserted into each guide sleeve 8. The lower end of each guide rod 9 is fixedly connected to the pressure plate 5. A cylinder 10 is fixedly installed on the bracket 2. The output end of the cylinder 10 is fixedly connected to the center of the top of the pressure plate 5.

[0024] Heated soy milk is poured into forming tank 4 and allowed to solidify into tofu skin. Then, cylinder 10 moves pressure plate 5 into forming tank 4 to press the tofu skin. Water pressed out during this process is filtered through filter cloth 7 and discharged through multiple drain outlets 6. This timely drainage of water from the tofu skin during pressing makes it firmer and more uniform in texture, preventing it from becoming loose or brittle due to excessive moisture. The firmer tofu skin has a more elastic texture, meeting consumer preferences for the taste of soy products.

[0025] The pressure plate 5 is hollow inside. When the pressure plate 5 moves into the forming groove 4, it can seal the upper port of the forming groove 4. A first heating element 11 is fixedly installed inside the pressure plate 5, and the pressure plate 5 is made of heat-conducting metal. A second heating element 12 is provided in each of the drain outlets 6, and the second heating element 12 is fixedly installed on the forming groove 4.

[0026] During the pressing process, the first heating element 11 heats the pressing plate 5, while the second heating element 12 heats the area below the heating filter cloth 7. This heats both sides of the tofu skin within the forming tank 4, ensuring the tofu skin reaches a moderate temperature. This prevents the tofu skin from becoming too soft due to excessively low temperature, which would hinder the formation of the desired texture. Pressing at this moderate temperature also ensures the tofu skin has an ideal taste and flavor. The moderate temperature helps the protein molecules coagulate appropriately, resulting in tofu skin that is neither too hard nor too soft, but possesses just the right amount of firmness and elasticity.

[0027] The machine base 1 is fixedly mounted with a support frame 13, and a feeding mechanism is mounted on the support frame 13. The feeding mechanism is used to add heated soy milk into the forming tank 4. The feeding mechanism includes a first pipe 14 fixedly connected to the support frame 13. The upper end of the first pipe 14 is connected to the discharge pipe of an external pressure pump, and the inlet pipe of the external pressure pump is connected to an external soy milk tank. A slidable movable pipe 15 is inserted into the first pipe 14 and is connected to the first pipe 14. One end of the movable pipe 15 has a liquid outlet hole 16. A valve 17 is installed on the first pipe 14. An electromagnet 18 is fixedly installed at the bottom of the first pipe 14. A magnet 19 is fixedly installed on the movable pipe 15. A block 20 is fixedly installed at the upper end of the movable pipe 15, and a cushioning pad 21 is fixedly connected to the block 20.

[0028] During the discharge process, an external pressure pump introduces the soy milk from the external soy milk bucket into the first pipe 14, and after passing through the movable pipe 15, it is discharged into the molding tank 4 through the liquid outlet 16. The valve 17 is a solenoid valve. By controlling the opening time of the valve 17, an appropriate amount of soy milk is added to the molding tank 4, avoiding the problem of large errors caused by manual addition.

[0029] Just before the pressure plate 5 is about to press down, the electromagnet 18 is energized and applies an attractive force to the magnet 19. The front end of the movable tube 15 moves away from the pressure plate 5, causing the movable tube 15 to leave the moving path of the pressure plate 5. The block 20 and the buffer pad 21 move synchronously. The buffer pad 21 cushions the block 20 and contacts the support frame 13, preventing the block 20 and the magnet 19 from colliding with the support frame 13. The buffer pad 21, placed on the magnet 19, affects the force between the electromagnet 18 and the magnet 19.

[0030] The working principle of this utility model is as follows: During the discharge process, the external pressure pump introduces the soy milk from the external soy milk bucket into the first pipe 14, and after passing through the movable pipe 15, it is discharged into the molding tank 4 through the liquid outlet 16. The valve 17 is a solenoid valve. By controlling the opening time of the valve 17, an appropriate amount of soy milk is added to the molding tank 4, avoiding the problem of large errors caused by manual addition.

[0031] Just before the pressure plate 5 is about to press down, the electromagnet 18 is energized and applies an attractive force to the magnet 19, causing the front end of the movable tube 15 to move away from the pressure plate 5, thus moving the movable tube 15 away from the moving path of the pressure plate 5.

[0032] After the heated soy milk is poured into the forming tank 4, it solidifies into tofu skin. Then, a cylinder 10 moves a pressure plate 5 into the forming tank 4 to press the tofu skin. Water pressed out during this process is filtered through a filter cloth 7 and discharged through multiple drain outlets 6. This timely drainage of water from the tofu skin during pressing makes it firmer. During pressing, the first heating element 11 heats the pressure plate 5, and the second heating element 12 heats the area below the filter cloth 7, thus heating both sides of the tofu skin in the forming tank 4 to maintain a suitable temperature. The resulting tofu skin is neither too hard nor too soft, but possesses just the right amount of toughness and elasticity.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
