Description

A centrifugal spray dryer for grain powder processing

Technical Field

The utility model relates to the field of grain powder processing, and more specifically, to a centrifugal spray dryer for grain powder processing.

Background Art

Cereals are vital and indispensable in people's lives. Cereals have extremely high nutritional value and can meet people's different nutritional needs. In the process of cereal production, it is often necessary to make various granular cereals into powder to form cereal powder. In the process of cereal powder production, the cereal powder needs to be dried to meet production needs. Therefore, a centrifugal spray dryer is needed to dry the cereal powder. When the existing centrifugal spray dryer is in use, the cereal powder is atomized and sprayed out by a centrifugal atomizer, and the cereal powder is contacted with hot air in the dryer to dry the cereal powder. Due to the atomization spraying method, the cereal powder is easily adhered to the cylinder wall of the dryer, thereby causing the loss of cereal powder and increasing the production cost. In addition, after the existing centrifugal spray dryer has dried one cereal powder, it needs to be cleaned before drying another cereal powder again, thereby increasing the time required for production and having low production efficiency.
