Corn steep liquor is a by-product of corn starch production. The manufacture of cornstarch first soaks corn kernels in sulfurous acid, and the soaking solution is concentrated to make a yellow-brown liquid called corn steep liquor. Corn steep liquor is rich in soluble protein, auxin and some precursor substances, and contains about 40% to 50% solid matter. Corn steep liquor is a commonly used organic nitrogen source for microbial growth, and it also promotes the synthesis of antibiotics, such as penicillin.
The principle of high-speed centrifugal spray dryer for corn steep liquor:
The so-called high-speed centrifugal spray dryer uses a centrifugal atomizer to dry some liquid materials, and is one of the most widely used dryers in industrial production. Spray drying is a widely used process for forming and drying liquids. It is suitable for producing powdery and granular solid products from solution, emulsion, suspension and pasty liquid raw materials. Therefore, spray drying is an ideal process when exact criteria are met for particle size distribution, residual moisture content, bulk density and particle shape.
Corn steep liquor high-speed centrifugal spray dryer features:
1. Fast drying speed, suitable for heat sensitive materials;
2. The product has good uniformity, fluidity and solubility, high purity and good quality;
3. The production process is automated and the operation is simple;
4. Product size, bulk density and moisture content can be adjusted within a certain range.
