Description

Enzyme-killing equipment for grain processing

Technical Field

The utility model relates to a grain processing and fresh-keeping equipment especially relates to a grain processing enzyme equipment that goes out.

Background

The grain such as rice germ has protein and lipid content above 20%, amino acid composition in protein is balanced, natural vitamin E in lipid is about 200mg-300mg/100g, and fatty acid above 70% is unsaturated fatty acid, and has reasonable composition. In addition, the rice germ also contains various vitamins, dietary fibers and mineral substances, so the rice germ is a health food with rich nutrition. However, in the existing rice processing, in order to seek better taste, the polishing is thorough, so that the finished rice only has starch and a small amount of protein, and nutrient components such as cellulose, vitamins and the like are basically polished and removed. Accordingly, a germ-retaining rice (also called germ-retaining rice) capable of retaining germs in the finished rice and a method for processing the same have been sought. However, the germ in rice is active and easily spoils. In the rice processing process, the rice is in close contact with biological enzymes and microorganisms, especially when the processing temperature reaches 31-65 ℃, rice germs are easily polluted and can quickly start hydrolysis reaction, rancidity can occur in a short time, and the rice cannot be preserved for a long time, so that the rice with the germ cannot be eaten and cannot be stored for a long time.
