Description

Technical Field

[0001] This invention relates to the field of soybean product processing technology, and more specifically to a soybean product processing method. Background Technology

[0002] Soybeans can be processed into various soy products, such as soy milk and bean curd sheets. Soaking the soybeans during processing is crucial to prevent spoilage. On the other hand, because bean curd sheets need to be spread out during processing, covering a large area, specialized personnel are required for collection. These personnel need to manually clean and collect the scattered bean curd sheets for further processing. In large factory areas, more manpower is needed to cover the entire work area and ensure timely processing of bean curd sheets, resulting in high labor costs and room for improvement in work efficiency. Summary of the Invention

[0003] This invention provides a method for processing soybean products, which has the advantage of improving the processing efficiency of soybean skin.

[0004] The above objectives are achieved through the following technical solutions:

[0028] A method for processing soybean products includes the following steps:

[0029] Step 1: Rinse the soybeans with running water and soak them in drinking water for 6-12 hours at a water temperature of 8-12℃.

[0030] Step 2: After grinding the wet soybeans with water, grind them again with water, then stir to obtain soy milk;

[0031] Step 3: After filtering out the soybean pulp, the soy milk is heated and cooked.

[0032] Step 4: Pour the cooked soy milk into a soy product processing device and let it stand to obtain soy skin;

[0033] Step 5: Remove the bean curd sheets and hang them to air dry.

[0034] Soybeans should be washed with running water before soaking and then soaked in drinking water.

[0035] The soybean product processing equipment includes an open-top container 11, preferably a cuboid with its interior space extending laterally along its long side. Soy milk can be directly poured into the container 11, or a shallow mold can be placed inside. A vertical guide frame I12 is fixed to the front end of the upper part of the container 11, and a horizontal guide frame I13 is fixed to the vertical guide frame I12. The horizontal guide frame I13 communicates with the vertical guide frame I12. A straight opening 14 is provided at the upper end of the horizontal guide frame I13. A hanging bracket 15 is hung on the container 11, with its front part slidably connected to the vertical guide frame I12 and its rear part hanging on the rear end of the upper part of the container 11. The middle part of the hanging bracket 15 is recessed downwards. A motor I21 and a base frame 23, both fixed to the ground, are located on the rear side of the container 11. The output shaft of the motor I21 faces upwards. The upper end of the output shaft is fixedly connected to the first lead screw 22, and the base frame 23 is fixedly connected to the second lead screw 22. The lower parts of the two lead screws 22 are synchronously driven by a pulley belt assembly. The two lead screws 22 are screw-driven with a bracket 24. The bracket 24 is located below the hanging frame 15. The upper end of the bracket 24 is fixedly connected to a protrusion 25. The starting motor I 21 is used to drive the lead screw 22 to rotate. The lead screw 22 drives the bracket 24 to rise and fall. After the protrusion 25 rises with the bracket 24, the bracket 24 lifts the hanging frame 15. The protrusion 25 can contact the rear end face of the hanging frame 15. Thus, the bracket 24 drives the hanging frame 15 to move upward along the vertical guide frame I 12. When a bean skin forms on the surface of the soy milk in the container 11, the hanging frame 15 moves upward from the soy milk until it lifts the bean skin. The hanging frame 15 contacts the bean skin surface, increasing the lifting area. The bean skin moves upward to the horizontal guide frame I 13.

[0036] Furthermore, a base 31 is slidably connected inside the straight opening 14. An electromagnet 34 is fixedly connected to the lower end of the base 31. The upper end surface of the electromagnet 34 can slide relative to the inner horizontal surface of the upper end of the horizontal guide frame I 13. A motor II 32 is fixedly connected to the base 31. The output shaft of the motor II 32 is set downward. A wheel 33 is fixedly connected to the output shaft of the motor II 32. The wheel 33 rolls and rubs against the front end face of the horizontal guide frame I 13. When the motor II 32 drives the wheel 33 to rotate, the wheel 33 drives the base 31 to rotate. The base 31 moves left and right along the horizontal guide frame I13. The lower right side of the electromagnet 34 has a groove, and a leaf spring 35 fixed to the electromagnet 34 is provided in the groove. The leaf spring 35 is V-shaped and the opening faces left. When the hanging frame 15 is raised into the horizontal guide frame I13, the base 31 moves from the right side of the horizontal guide frame I13 to the left until the leaf spring 35 is stuck on the hanging frame 15. At the same time, the electromagnet 34 is activated to attract the hanging frame 15, which drives the hanging frame 15 to move to the left to leave the bean skin scooping area.

[0037] Preferably, the container 11 is provided with a support, a mold is placed on the top of the support, the middle part of the hanging rack 15 is located inside the mold, the soy milk is poured into the mold, an electric heating element is provided below the mold, and the mold is in contact with the water in the container 11.

[0038] Preferably, the left end of the horizontal guide frame I13 is fixedly connected to and connected to a horizontal guide frame II41, which is connected to the straight opening 14. The lower end of the horizontal guide frame II41 is fixedly connected to and connected to a vertical guide frame II42. Multiple vertical guide frames II42 are arranged in a linear array in the left and right directions. A vertical guide frame III43 is arranged on the rear side of the vertical guide frame II42. The number of vertical guide frames III43 is the same as the number of vertical guide frames II42, and their positions correspond. Both the vertical guide frames II42 and III43 have horizontal openings to form shoulders. The horizontal openings are distributed longitudinally, and the distance between two adjacent horizontal openings is greater than the longitudinal length of the bean curd skin hanging on the hanging rack 15. Water is placed on the shoulders. The horizontal frame 44 can be pulled away from the vertical guide frames II 42 and III 43 in the left and right directions, facilitating forklift transport. The hanger 15 can be transported to the vertical guide frame II 42 by the coordinated action of the electromagnet 34 and the triangular leaf spring 35. When the front part of the hanger 15 slides to the vertical guide frame II 42, the rear part of the hanger 15 is located in the corresponding vertical guide frame III 43. The electromagnet 34 stops using magnetic force to attract the front part of the hanger 15, and the hanger 15 falls onto the lowest horizontal frame 44. When the lowest horizontal frame 44 is full of hangers 15 from left to right, a second horizontal frame 44 is added to the lowest horizontal frame 44.

[0039] Preferably, it also includes a fan that provides airflow to the horizontal frame 44, the airflow moves in the back-and-forth direction, ventilation openings are provided on the vertical guide frame II 42 and vertical guide frame III 43, and an isolation plate 5 is provided between the horizontal frame 44 and the container 11 to guide the airflow. (Refer to...) Figure 1 The container 11 can be arranged in a linear array in the left and right directions. By adding corresponding hangers 15 and vertical guides I 12, and extending horizontal guides I 13 and brackets 24, this application can be arranged in a linear array in the front and back directions in the factory to fill the site.
