Description

A fine material collection device of a high-speed centrifugal spray dryer

technical field

The utility model relates to the technical field of a high-speed centrifugal spray dryer, in particular to a fine material collecting device of a high-speed centrifugal spray dryer.

Background technique

Centrifugal spray dryer is the most widely used process in liquid forming process. Best suited for the production of powdered products from solutions, emulsions, suspensions and pasty liquid raw materials. The raw materials are transported to the atomizer at the top of the tower by the feeding pump, and then thrown out from the high-speed rotating atomizing disc to form fine mist droplets. The mist droplets are in contact with the hot air inside the drying tower. The water in the water is evaporated instantly, and the solid matter in the mist droplets forms a powder product. The fine powder and evaporated water vapor are discharged from the bottom of the drying tower along with the tail gas, and the fine powder is collected after gas-solid separation by the cyclone separator.
