Multistage screening plant of soybean seed
Technical Field
The invention relates to the technical field of agriculture, in particular to a soybean seed multistage screening device.
Background
Soybean is cultivated in China and is widely cultivated all over the world. Soybean is one of the important grain crops in China, has been cultivated for five thousand years, is called Shushu in ancient times, and is a crop with seeds containing rich plant protein, wherein northeast China is the main production area. Soybeans are most commonly used for making various bean products, extracting soybean oil, brewing soy sauce, and extracting proteins. Okara or soybeans ground into meal are also commonly used in livestock feed. Soybean planting requires screening of soybean seeds. Plump soybeans were selected as seeds. The soybeans were rolled on a plate manually, and thus the filled soybeans were selected as seeds.
