Description

Technical Field

[0001] This utility model relates to the field of soybean milk residue removal technology, and in particular to a soybean milk residue removal device for fermented bean curd production. Background Technology

[0002] Fermented bean curd, also known as tofu curd, is loved by many for its good taste, high nutritional value, and fragrant flavor. It is made by fermenting soy milk into tofu, which is then fermented to make fermented bean curd. The soy milk used to make fermented bean curd must be pure, with the soy pulp removed. After the soy milk is ground, it needs to be separated from the soy pulp. Soy pulp, also called soybean residue, is the residue left after filtering the soy milk during the soy milk making process. Soy pulp contains a variety of nutrients such as protein, fat, calcium, phosphorus, and iron, and can be used to make various delicacies.

[0003] The currently published patent, CN213077643U, discloses a device for removing slag from cooked soybean milk used in fermented bean curd production. This device features a pressure plate and a transmission column above the slag removal tank, with an upper pressure plate above the transmission column. Utilizing a hydraulic column, the device can quickly and efficiently separate soybean milk slag from soybean milk juice. A metal filter screen is installed at the connection between the outer ring and the discharge column, and a cavity adapted to the discharge column is opened at the bottom of the slag removal tank. With the assistance of a filter cloth, the separated soybean milk juice can achieve high purity.

[0004] Based on the above search results, when using this soy milk residue removal equipment, the hydraulic column can quickly and efficiently separate soy milk residue from soy milk juice. However, the operator can only process one can of soy milk residue and soy milk juice at a time. After the soy milk juice is squeezed out, the operator needs to discharge the soy milk residue and then put in a new can of cooked soy milk before the new cooked soy milk can be squeezed again. This makes it impossible to continuously squeeze the cooked soy milk, which reduces the residue removal efficiency of cooked soy milk. Utility Model Content

[0025] Please see Figure 1-4This utility model provides a technical solution: a soybean milk slag removal device for fermented bean curd production, including a mounting base plate 1 and a continuous soybean milk slag removal device. Two support frames 2 are fixedly connected to the top of the mounting base plate 1. The continuous soybean milk slag removal device includes a metal filter screen 3, a feed pipe 4, an extrusion cylinder 5, a drive motor 7, and a rotating shaft 8. The metal filter screen 3 is fixedly installed inside the two support frames 2. The feed pipe 4 is fixedly connected to the top of the metal filter screen 3. The extrusion cylinder 5 is rotatably installed inside the metal filter screen 3. A spiral extrusion groove 6 is formed on the surface of the extrusion cylinder 5. The depth of the extrusion groove 6 gradually decreases from right to left. The drive motor 7 is fixedly installed on the top of the mounting base plate 1. The rotating shaft 8 is rotatably installed on the right end of the metal filter screen 3. The left end of the rotating shaft 8 is fixedly connected to the right end of the extrusion cylinder 5. The right end of the rotating shaft 8 is fixedly connected to the output end of the drive motor 7. A semi-circular collection box 9 is fixedly connected to the top of the mounting base plate 1. A discharge pipe 10 is fixedly connected to the bottom of the semi-circular collection box 9. A valve 11 is installed at the end of the discharge pipe 10 away from the semi-circular collection box 9. A soybean residue collection box 12 is fixedly connected to the left end of the mounting base plate 1.

[0026] The worker pours cooked soy milk into the metal filter 3 through the feed pipe 4. After entering the metal filter 3, the cooked soy milk automatically flows into the spiral extrusion groove 6 under its own gravity. After the worker starts the drive motor 7, the output end of the drive motor 7 rotates and drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the extrusion cylinder 5 to rotate inside the metal filter 3. The rotation of the extrusion cylinder 5 drives the spiral extrusion groove 6 to rotate, and the cooked soy milk gradually moves to the left through the spiral extrusion groove 6. As the depth of the spiral extrusion groove 6 gradually decreases from right to left, the storage space for the cooked soy milk gradually decreases as it moves to the left, thus extruding the cooked soy milk. At this time, the soy milk juice squeezed out can be discharged to the outside through the metal filter 3. After being discharged to the outside of the metal filter 3, the soy milk juice falls downwards into a semi-circular shape under its own gravity. Inside the collection box 9, after the staff opens the valve 11, the soy milk stored inside the semi-circular collection box 9 can be released through the discharge pipe 10, making it convenient for the staff to process the soy milk. The spiral extrusion groove 6 rotates and drives the soy milk residue to gradually move to the left and out of the metal filter screen 3. When the soy milk residue moves to the left end of the extrusion cylinder 5, it will automatically fall to the side under its own gravity into the soy milk residue collection box 12. The soy milk residue can be stored in the soy milk residue collection box 12. At this time, the staff can continuously add cooked soy milk into the metal filter screen 3 through the feed pipe 4, and continuously extrude and remove residue from the cooked soy milk by rotating the extrusion cylinder 5. The soy milk juice and soy milk residue are collected separately by the semi-circular collection box 9 and the soy milk residue collection box 12. This soy milk residue removal device can continuously extrude and remove residue from cooked soy milk, improving the residue removal efficiency of cooked soy milk.

[0027] An L-shaped mounting bracket 13 is fixedly connected to the top of the left support frame 2. Two guide rods 14 are fixedly connected to the left end of the L-shaped mounting bracket 13. A cleaning brush 15 is slidably connected to the lower end of the two guide rods 14. The bottom of the cleaning brush 15 is in contact with the surface of the extrusion cylinder 5. Springs 16 are slidably sleeved on the surface of the two guide rods 14. The upper end of the two springs 16 is fixedly connected to the surface of the L-shaped mounting bracket 13, and the lower end of the two springs 16 is fixedly connected to the top of the cleaning brush 15.

[0028] Both springs 16 are in a compressed state. When the springs 16 release their elasticity, they drag the cleaning brush 15 to slide downwards on the surface of the two guide rods 14. The two guide rods 14 can guide and position the cleaning brush 15. The cleaning brush 15 slides downwards and presses against the left end of the extrusion cylinder 5. When the soy pulp moves to the left end of the extrusion cylinder 5, the cleaning brush 15 can sweep the soy pulp off, preventing it from getting stuck inside the spiral extrusion groove 6. This allows the soy pulp inside the metal filter screen 3 to continuously move to the left and be discharged, ensuring that the soy pulp can be smoothly discharged from the inside of the metal filter screen 3.
