Working principle of spray dryer

Working principle of spray dryer

A spray dryer is a device that can dry and granulate simultaneously. According to the process requirements can adjust the feed pump pressure, flow and the size of the spray hole. Thus, the required spherical particles with a certain size ratio can be obtained. The spray dryer uses special equipment to spray the liquid into a spray, which is ...

Spray Drying Process Spray Dryers Spray Drying Technology

A spray dryer, as the name implies, is a device for drying, utilizing a spray. A spray dryer mixes a heated gas with an atomized (sprayed) liquid stream within a vessel (drying chamber) to accomplish evaporation and produce a free flowing dry powder with a controlled average particle size. The unit operation of spray drying includes the ...

How Spray Dryer Principle

In principle, a hobby spray booth uses a fan to pull air through a filter and either exhausts the “cleaner” air in one of two ways: 1) it exhausts the air back into the room (a ventless system), or 2) pushes the air through a tube out of the ambient space (a vented spray booth).

Spray dryer working principle

The working principle of spray drying: Spray drying is a drying process in which raw materials are dispersed into droplets with an atomizer, and hot air (or other gas) is directly contacted with the droplets to obtain a powdery granular product. After filtering and heating, the air enters the hot air distributor on the top of the dryer.
