The corn steep liquor is a byproduct for preparing corn starch, contains rich soluble protein, auxin and a plurality of precursor substances, and has the solid content of about 40-50 percent. Corn steep liquor is an important raw material for preparing a culture medium and can provide an organic nitrogen source necessary for the growth of microorganisms. Because the corn steep liquor is liquid, the storage, the transportation and the like are inconvenient. Therefore, there is a need to prepare corn steep liquor as a dry powder. Most dry corn steep liquor powders are produced by spray drying, which requires a large amount of heat to be used in the production process. The drying mode has great energy consumption, and the high energy consumption leads to the rise of the production cost. There is therefore a need to find a way to reduce the energy consumption of production.
