Information

The internal quality of corn steep liquor powder is the same as corn steep liquor, but the moisture content is less, because the product is powdery solid, easy to transport, storage and use, the product is not easy to deteriorate, easy to use, the yield and quality of the product are stable. But the corn steep liquor is inconvenient to transport, store and use because of the liquid big barrel packing. Due to the high content of protein and trace elements, it is easy to ferment and deteriorate at a higher temperature, which affects the use effect. The disadvantage is that low temperature spray drying technology has high production cost. It is difficult to introduce convenient fermentation factories for corn steep liquor, and is suitable for fermented enterprises far away from corn starch producing areas. The quality of corn steep liquor powder is judged by its color. The more protein is destroyed, the worse the quality of corn steep liquor powder is. On the contrary, the lighter the color is, the less protein is destroyed, the better the quality of corn steep liquor powder is.

 

Corn steep liquor powder is widely used in antibiotic industry (penicillin, erythromycin, gentamicin, spectinomycin, chlortetracycline, etc.), vitamin (VC, VB2, etc.), amino acid (monosodium glutamate, lysine, phenylalanine, etc.), enzyme preparation (amylase, glucoamylase, etc.) and other fermentation industries. It is used as water-soluble vegetable protein, water-soluble vitamin and other nutrient supplements in biological fermentation process 。 Corn steep liquor powder is sifted through the vibrating screen, and is taken through the screen hole. The soaking temperature should not exceed 55 degrees, otherwise the growth of lactic acid bacteria will be affected. Countercurrent soaking is adopted to release corn steep liquor. The general political method is multi effect film evaporator evaporation method. Corn seed, producing area and growth cycle are the key factors affecting the quality of corn steep liquor powder. As fermentation practitioners, it should be judged that the temperature and time of impregnation should indirectly affect the quality of corn steep liquor powder by affecting the type and quantity of microorganisms in corn steep liquor powder, and the metabolism of microorganisms on corn steep liquor powder is the main factor affecting the quality of corn steep liquor powder. There are two ways to accelerate the liquid evaporation: vacuumizing to reduce the boiling point of liquid, and rotating the material bottle to produce a thin liquid film on the inner wall of the bottle to accelerate the evaporation.
