Product Introduction

Centrifugal spray dryer is widely used in liquid forming and drying industry. It is suitable for generating powder and granular solid products from solution, lotion, suspension and paste liquid raw materials. Therefore, spray drying is a very ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet accurate standards.

working principle

The spray dryer is open circulation, parallel flow and centrifugal atomization. The drying medium air is filtered by the primary and medium efficiency air filters, and then absorbed by the blower according to the operation instructions, heated by the heater, and enters the spray drying main tower through the hot air distributor of the filter. The liquid material passes through the peristaltic pump according to the operating instructions and enters the high-speed rotating centrifugal nozzle, where it is dispersed into small droplets under the action of centrifugal force. In the main spray drying tower, small droplets are in full contact with the hot air, and after heat exchange along their specific path, they are dried into products, which are then separated through the cyclone separator. Solid materials are collected, and the gas medium is filtered and discharged. The whole set of spray system is easy to clean and complies with GMP requirements.
