Description

Technical Field

[0001] The utility model relates to the field of peanut seed processing, in particular to a multi-layer screening mechanism for color sorting of peanut seeds. Background Art

[0002] Peanut kernel refers to the part without the shell, which is actually the seed of peanut. The whole peanut is called fruit or pod. It is also called peanut rice, ground peanut, ground fruit, and Chinese bean. Peanuts are nourishing and can prolong life, so they are also called "longevity fruit" by the people. Like soybeans, they are also known as "vegetable meat" and "vegetarian meat". The nutritional value of peanuts is higher than that of grains and can be comparable to eggs. Peanut seeds need to be screened several times during the processing to sort out peanut seeds of different particle sizes.

[0003] Current multi-layer screening devices usually have multiple screening layers. First, a large amount of peanut seeds are poured onto the first screening layer, and then screened step by step. However, the sizes of the peanuts on the first screening layer vary greatly, and the amount of peanut seeds on the first screening layer is the largest. Therefore, the first screening takes a longer time, and some smaller peanut seeds may not be screened out and will be discharged together with the large peanuts, resulting in average screening effect.
