Description

Technical Field

[0001] The utility model relates to the technical field of food production, in particular to a bean powder grinding and rapid screening device. Background Art

[0002] Bean grinding technology is an important part of the food industry. The main reason is that beans are rich in nutrients such as plant protein, dietary fiber, vitamins and minerals, and do not contain cholesterol. They have many benefits to human health. Bean grinding, that is, processing beans into powder through specific machinery, can not only improve the utilization rate and added value of bean products, but also make it easier for people to eat and digest and absorb.

[0003] Publication No. CN210965429U discloses a novel bean grinding device, which exerts a thrust on the beans in contact with the pressing plate arranged obliquely on the fixed frame during rotation. Meanwhile, the beans themselves have a certain gravity and resistance to each other. Through the cooperation of thrust, gravity and resistance, the beans are subjected to an oblique downward pressure when the pressing plate rotates, so that they can fall under the grinding seat for better grinding. The position of the lower end of the grinding seat can be adjusted to a certain extent. The position of the lower end of the grinding seat can be adjusted by hand by rotating the rotating seat at a certain angle, thereby adjusting the size of the powder particles after grinding. However, the patent still has the following problems in actual use:

[0004] The device exerts a certain downward pressure on the beans during the bean grinding process, which facilitates the beans to fall better under the grinding seat for grinding. At the same time, the device can also adjust the size of the powder particles after grinding to a certain extent. However, after the device grinds the beans, there may be large particles that are not completely crushed in the collection box. Since the device does not have a screening structure, the quality of the bean powder collected by subsequent staff is poor, which brings inconvenience to the staff when using it.

[0005] A bean powder grinding and rapid screening device is proposed to solve the above problems. Utility Model Content
