Corn steep liquor is a concentrated liquid extracted from the water used in the initial stages of the corn wet grinding process. Using fresh Corn steep liquor as raw material, the Corn steep liquor powder was obtained by instantaneous heating at low temperature and spray drying. This way the water-soluble proteins are well preserved and the product retains all its properties. Because the heating method is steam heating, so the product without impurities and coking phenomenon.

Steeping a procedure used during wet corn milling. The major objectives for corn steeping are to induce chemical and physical changes in the kernel by leaching the soluble components from the corn. Cleaned shelled corn is soaked for 30-48 hours at 45℃-50℃ in a solution. The steeped liquid is then separated from the non-soluble corn solids , which are further separated into germ, bran, starch, and gluten protein. The steeped liquid is concentrated by triple-effect steam evaporator to corn steep liquor which contains dry matter of 45-55%.

The corn steep liquor will be stored into storage tank after purification firstly by sieves and secondly by bag-filters.
Heat treatment of 100 degree for 30 minutes,high temperature kills harmful substances

When ready for production, get the corn steep liquor stirred in the stirring tank and get it heated under the temperature of 40℃ and then fed into the spraying dry tower. The corn steep liquor will be spray dried into corn steep liquor powder in the tower (Inlet air is about 140℃）
