Introduction
Centrifugal spray dryer is the most widely used drying technology in drying technology.
It helps simple and effective drying of liquid or suspension materials. In addition, during the drying process, the user can control the temperature of the dried product, form the grain for them exactly as required for production.
The device has advantages compared to conventional drying equipment: hot air is put into the dehumidifying filter to help quick drying time; Product quality is improved; continuous machine operation, complete automation, simple operation, easy maintenance, low labor costs; The device is designed to suit a wide range of products, especially temperature-sensitive materials.
