Grain processing machinery is a kind of mechanical equipment specially used for processing grains. It mainly includes cleaning, screening, grinding, drying, packaging and other processes. Grain processing machinery has a very wide range of applications. From food processing in daily life to raw material processing in industrial production, grain processing machinery is inseparable.
Cleaning is the first process of grain processing machinery. Grains will be contaminated by dust, impurities, microorganisms, etc. during planting, harvesting, and transportation, so they need to be cleaned before processing. There are many cleaning methods, such as water washing, air flow cleaning, screening cleaning, etc. The washed grains will be cleaner and more hygienic, providing a good foundation for subsequent processes.
Screening is the second process of grain processing machinery. Screening refers to separating grains according to characteristics such as size, weight, density, etc., to facilitate subsequent processes. There are many ways of screening, the common ones are vibrating screen, rotating screen, air flow screen, etc. After screening, the grain quality is more uniform, which is beneficial to the subsequent grinding process.

Milling is one of the core processes of grain processing machinery. Milling is the process of grinding grains into powder. It can be divided into two methods: dry grinding and wet grinding. Dry grinding is to grind grains directly after screening. It is suitable for grinding dry grains such as grains and beans. Wet grinding method is to mix grains with a certain proportion of water and then grind them. It is suitable for grinding wet grains such as rice and noodles. The ground grain powder can be used to make pasta, biscuits, pastries and other foods.
Drying is the last process of grain processing machinery. Drying is the drying process of grain powder for better storage and transportation. There are many drying methods, such as natural drying, solar drying, hot air drying, etc. Different drying methods have different effects on grain drying. The dried grain powder can be packaged and stored for subsequent use.

In short, grain processing machinery is a very important food processing equipment. It can carry out multiple processes such as cleaning, screening, grinding and drying grains in order to produce various foods. Grain processing machinery has a very wide range of applications and is suitable for many fields such as grain and oil, food, medicine, and chemical industry. When using grain processing machinery, you need to pay attention to safety and hygiene and perform regular maintenance to ensure its normal operation.
