Description

Technical Field

[0001] The utility model relates to the technical field of bean product processing, in particular to a bean product raw material grinding device. Background Art

[0002] Soy products are processed from soybeans, such as tofu, tofu silk, dried tofu, soy milk, tofu brain, yuba, bean sprouts, etc. Because soybeans are processed, not only the protein content is not reduced, but also the digestion and absorption rate is improved. At the same time, various soy products are delicious and promote appetite. Bean sprouts are also rich in vitamin C, which can play a role in regulating the winter and spring seasons when vegetables are scarce.

[0003] After searching, Chinese patent publication number CN219308861U discloses a bean product processing raw material grinding equipment, including a grinding cylinder, a column, a horizontal plate, a motor, an anti-overflow cover, a rotating shaft, a grinding disc, and a discharge port. The grinding cylinder is fixed on a bracket by bolts, a column is provided on one side of the grinding cylinder, the height of the column is greater than the height of the grinding cylinder, a horizontal plate is provided on the column, a motor is installed below the horizontal plate, and the motor can move along the length of the horizontal plate. A grinding disc installed by screws is provided in the grinding cylinder, the grinding disc and the grinding cylinder are designed to be concentric, a rotating shaft is provided at the center of the grinding disc, and the rotating shaft can rotate under the action of the motor, a discharge port is opened on one side of the bottom of the grinding cylinder, the grinding cylinder is hollow, and an anti-overflow cover installed by screws is provided above the inside of the grinding cylinder, and the diameter of the anti-overflow cover is smaller than the diameter of the grinding cylinder. The utility model has a reasonable design; the grinding disc and the blocking rod can divide the beans to prevent the beans from moving over a large range during grinding and affecting the grinding.

[0004] However, in the above technical scheme, only the limit frame with magnets and the blocking rod can slide in the through groove on the grinding disk when the blocking rod moves down through the principle of opposite charges attracting and like charges repelling. After the external force is lost, the blocking rod can be automatically reset to divide the beans and prevent the beans from moving during the grinding process. However, if some soybeans are not soaked for enough time during processing, their hardness will be high. When grinding, they will be between the blocking rod and the grinding rod, which may cause the blocking rod to move down excessively in the through groove and out of the through groove, causing dislocation, affecting the subsequent bean grinding. As the magnet is used, its magnetic force will gradually decrease, making it more likely that the blocking rod cannot be reset. At the same time, some beans will still be incompletely ground after grinding, and such beans will be mixed in the bean powder, reducing the quality of the bean powder. Utility Model Content
