Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening assembly, especially to a bean brewing and screening device. BACKGROUND

[0002] Bean brewing refers to soaking bean food materials (such as green beans, red beans, soybeans, etc.) in water for a period of time, so that they absorb water and swell, and the internal structure is softened, so as to facilitate subsequent cooking or processing. This processing method is very common in cooking and is mainly used to improve the taste and cooking effect of beans.
