spray dryer

The closed-loop spray drying system uses an inert gas (generally N2) as the carrier to transfer heat, used in a in a closed cycle. it is beneficial for conserving the heat carrier, recovering organic solvents, preventing atmospheric pollution from toxic substances, and avoiding material oxidation.

This industrial spray dryer adopts rotary cutting air inlet technology and adjustable volute structure, which ensures even material distribution and effectively avoids material reverse jacking. Multiple heat source options are available, including electric heating, steam heating and combined heating modes, realizing high working efficiency with low energy consumption. The machine features compact and elegant overall structure, simple operation, detachable and cleanable hot air chamber, as well as adjustable and controllable inlet air temperature. Equipped with air jacket cooling system on the drying chamber wall and top, it prevents materials from thermal melting and wall adhesion. The built-in air rotary blowing device further reduces wall sticking. The powder collection system applies dehumidified air conveying and cooling technology to cool finished products and avoid moisture absorption and agglomeration. It fully complies with GMP standards, with drying air cleanliness above 100,000 grade. Easy to clean and maintain, it delivers stable product quality, ideal for pharmaceutical, food, chemical and energy industry production.

- GMP-compliant design; drying air cleanliness better than Class 100,000, quick-clean surfaces, consistently stable product quality. - Ultra-fast drying: after atomization the droplet surface multiplies, so 95–98% of moisture evaporates within 5–40 s in the high-temperature airflow.

① Adopt rotary cutting air inlet technology and adjustable volute to ensure uniform distribution of materials and no reverse top. ② The heat source can be electric heating, steam heating or a combination of various heating methods to ensure high efficiency and low consumption.

Spray dryer is a widely used process in powder forming and drying industries. It is suitable for producing powdery and granular products from liquid raw materials such as solutions, emulsions, suspensions, and pastes. Therefore, spray dryer is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise criteria. Spray dryer is suitable for food, pharmaceutical, energy and chemical fields.
