Closed-Circuit Spray Dryer

Spray Drying Technology:Spray drying technology is a method where liquid raw materials are dispersed into mist droplets within a drying chamber, and these droplets are dried using hot air to obtain the final product. The formation of droplets can be achieved by a rotary atomizer or a nozzle atomizer. The drying of the droplets can be accomplished by adjusting the temperature of the drying medium (typically air) or controlling the flow rate of the medium. The raw material can be in the form of a solution, emulsion, suspension, melt, or paste. The dried product can be made into powder, granule, hollow ball, or agglomerate form as per requirements.

Each set of spray dryer consists of several key components: a feed pump, an atomizer, an air heater, an air disperser, a drying chamber, a powder recovery system, and an exhaust air cleaning system.
Product Description

Closed-Circuit Spray Dryer Advanced Industrial Drying Solution​​​​​​​

Our Closed-Circuit Spray Dryer represents cutting-edge drying technology designed for your most demanding applications. This specialized equipment operates in a completely sealed environment using inert gases like nitrogen to protect sensitive materials from oxidation and contamination. The closed-circuit system makes it perfect for processing materials with organic solvents, toxic substances, or products prone to oxidation. Unlike traditional spray dryers, our product recirculates the drying medium after dehumidification, ensuring maximum efficiency and safety. You'll benefit from superior product quality while maintaining the highest safety standards in your production process.
