In the journey of grain, grain hulling technology plays a vital role. This process occurs during the grain processing stage. Through clever methods, the outer hard shell or cortex of the grain is peeled off to extract the rich nutrients and edible parts inside, making it easier to extract the inner bran, germ and endosperm. This improves the taste of food, increases nutritional value, and makes grains easier to process and digest. Do you know how to shell grains?

 1. Grinding technology:

Milling is a common method of hulling grains and is suitable for grains such as wheat and barley. Through the grinding equipment, the shell layer of the grain is gradually ground under the action of friction, thereby separating the edible part inside. This method can effectively remove the hard shell of grains and lay the foundation for subsequent processing.

 2. Vibration shelling technology:

Vibration shelling uses the mechanical vibration of the vibrating equipment to shake off the shell of the grain. This method is especially effective for some hard grains, such as corn. The power of vibration helps separate the husks from the grains, improving cleaning results.

 3. Hydraulic shelling technology:

Hydrohusking uses the impact of water to wash away the husks of grains. This method works on grains such as rice, often combining soaking and rubbing. Hydraulic shelling not only removes hard shells, but also helps clean impurities on the surface of grains and improves product hygiene.

 4. Air flow shelling technology:

Air husking works by using airflow to blow the husks off the grains. This method is suitable for small grains of grains, such as millet. Under the action of airflow, the outer shell of the cereal is easily peeled off, revealing the edible part inside.

 5. Chemical treatment technology:

In some special cases, chemical treatments are also used for grain hulling. This may include methods such as enzymatic hydrolysis, which uses chemical reactions to break down the outer layer of the grain, making it easier to break away. However, in food processing, special attention is required to ensure the safety and feasibility of chemical treatments.

The importance of grain shelling not only improves the overall quality and taste of food, but also provides basic raw materials for subsequent processing and manufacturing. The continuous innovation and application of modern grain shelling technology will provide more possibilities for the sustainable development of the food processing industry.
