Information

The technology of low temperature centrifugal spray drying is used to ensure that the ingredients of corn steep liquor are not damaged. It is widely used in the fermentation of industrial enzymes (amylase, glucoamylase, fungal enzyme, etc.), vitamins (VC, VB2, etc.) and amino acids (glutamate, monosodium glutamate, lysine, tryptophan, threonine, methionine, phenylalanine, etc.). Corn steep liquor powder is often used as a nutritional supplement for water-soluble vitamins and water-soluble plant proteins. It can also be used in the production and application of fermented fertilizer.

 

Corn steep liquor powder is a common organic nitrogen source in microbial growth. It also promotes the biosynthesis of antibiotics, amino acids and enzymes. In the process of biological fermentation, it is used as the supplement of water-soluble plant protein and water-soluble vitamin. Although the physical and chemical indexes of corn steep liquor powder of each manufacturer are close to each other, there are obvious differences in the microbial fermentation process of corn steep liquor powder due to the different raw materials, manufacturers and production processes, which has a great impact on the quality of the finished product of corn steep liquor powder production. It is especially suitable for microbial biochemical pharmaceutical fermentation.

 

Fresh corn steep liquor was prepared by instant heating and spray drying at low temperature, and the dried corn steep liquor powder with good water solubility was obtained, while all characteristics of corn steep liquor were maintained. The heating method is steam heating. The product is free of impurities and coking. Corn steep liquor powder is reddish brown to light yellow. It has a unique smell. No fermentation, mildew and other odor. It dissolves rapidly and completely. In the process of biological fermentation, it can be used as a nutritional supplement of water-soluble plant protein and water-soluble vitamin.

 

The preparation process of corn steep liquor powder is as follows:

1. Before soaking corn, remove impurities on corn surface by air drops and water washing.

2. Remove insoluble impurities in corn soaking solution through bag filter.

3. After four times of evaporation and concentration, the filtrate Baume reached 20-22 ℃.

4. the concentrate is filtered through a bag filter and then enters the spray drying tower to dry the finished product.

5. The finished product should be packed after passing the inspection.
