What is old bean powder?

It is soybean powder made from defatted soybeans. Soybean flour not only has the characteristics of high protein content and high unsaturated fatty acid content in soybean, but also has health care effects such as anti-aging and brain strengthening, and is a food with high nutritional value.

Soybean is native to China, and has been planted all over China, and also widely planted all over the world. Soybean is one of the important food crops in China, which has been cultivated for 5000 years. It was called glutinous rice in ancient times. Mainly produced in the northeast of China, the seeds are rich in protein.

Protein degreasing

The production of high-protein defatted soybean powder requires that defatted soybeans be crushed to an average particle size of 5 ~ 20 microns. If the particle size is larger than 20 microns, the high protein components cannot be completely separated; If the particle size is less than 5 microns, it is easy to mix in non-protein components, which will hinder the subsequent particle size classification.

A pulverizer for pulverizing defatted soybeans may be used as long as it does not heat the pulverized object during the pulverization process. Hammer mills, axial mills, rotary mills and other impact mills are usually used. And that rotate speed and processing time of the pulverize should be determined according to the selected pulverize. Usually, the peripheral speed of the pulverizer is 40 ~ 150m/s, and it can be pulverized in a few seconds.
