[0002] Liquor koji making is a very important part of the liquor brewing process. Liquor koji making is usually made from grains such as wheat, rice, and corn through processes such as starchification, saccharification, and fermentation, and then the koji is cultivated through specific fermentation technology. The koji contains a variety of yeasts and acid-producing bacteria, which are key factors in the fermentation process of liquor. The production process of liquor koji making is very complicated and requires strict control of temperature and humidity to cultivate high-quality koji. Good koji can promote the fermentation of liquor and provide a unique flavor, which has an important impact on the final quality of liquor.

[0003] When the raw materials for making liquor are wheat and other grains, they need to be processed before entering the warehouse. The purpose of the processing is to remove the impurities. At present, most liquor manufacturers use manual cleaning to remove impurities from raw materials. This method often requires a lot of labor, has high labor intensity, low cleaning efficiency, and is time-consuming and labor-intensive. It cannot meet the needs of large-scale raw material cleaning. The raw material cleaning equipment used by some companies also generally has problems such as poor screening effect, low screening efficiency, inconvenient material loading and unloading, and inconvenient use, which to a certain extent affects the efficiency of liquor production and processing.
