Problems solved by technology

The soy sauce precipitated particles are between nanometer and micrometer, and traditional high-speed centrifugation cannot be effectively separated from soy sauce crude oil
The existence of precipitation not only affects the color of soy sauce products, but also causes a large amount of precipitation at the bottom of the bottle during the shelf life of the product, which affects the appearance
Therefore, the soy sauce raw material rich in precipitation cannot be used in soy sauce, resulting in a large waste of crude oil resources and significantly reducing economic benefits
