It takes a series of processing and treatment processes to turn green beans into round soybeans. The specific steps are as follows:
1. Harvesting: When the soybeans are ripe, they need to be harvested. When harvesting, the whole soybean plant is picked and dried until the pods become dry.
2. Peeling: put the dried pods into the machine to remove the hard shell.
3. Separation: The peeled beans still have a layer of green film, which needs to be separated. When separating, soak the beans in clean water, and fish out after the film floats.
4. Drying: Put the separated soybeans into the dryer and evaporate the water to make soybeans more dry.
5. Skin grinding: There is a thin layer of dried soybeans that need to be rinsed. When grinding the skin, put the soybeans into the skin grinder and grind off the thin skin.
6. Grading: The ground soybean needs to be graded. Soy beans are classified according to size and shape to ensure quality.
7. Packaging: graded soybeans need to be packaged. Put soybeans into bags and seal them.
Through the above series of processing and treatment processes, green beans can become round soybeans.
