How to utilize the by-products of rice mill comprehensively?
The by-products of rice processing mainly include rice husk, rice bran, rice embryo, broken rice, etc. Deep processing of by-products can increase the value of rice resources by 3-5 times.
1. Although the recycling problem of rice husk waste has been solved by using rice husk for power generation, rice husk ash remains in the form of residue after the rice husk is used for power generation. Rice husk ash accounts for about 20% of the total mass of rice husk, and the main component is SiO2, with the content up to 60-95%. Rice husk ash can be used to make activated carbon, silicon carbide, silica and so on.
2. Rice husk can be used to produce xylose, xylitol, etc.; Xylitol is one of the best raw materials for chewing gum.
Rice husk can also produce furfural, bioethanol and so on.
3. Rice bran takes about 5%-7% of the quality of rice. Rice bran can be used as animal feed, and to press oil, which develops a variety of health food for the prevention of cardiovascular diseases, lowering blood sugar, blood fat, weight loss, anti-fatigue, beauty, etc.
4. In the process of rice production, 10%-15% of broken rice will be produced. Broken rice protein is a high-quality plant protein. Crushed rice starch can replace fat and be used as hand powder and other lubricants in the food and rubber industry. Broken rice can also be produced to rice bread, rice flour, rice drinks and so on.
The economic value of rice mill can be improved by using the by-products of rice mill comprehensively.
