Model: YJGZ-G
Closed-loop stainless steel spray dryer for organic-solvent solutions, using an inert-gas circuit and condensation system to dry materials without oxygen exposure.
This equipment is sold for lawful use only. Buyer is responsible for compliance with all applicable regulations.
The YJGZ-G is a laboratory-scale closed-loop spray dryer built for drying solutions, emulsions, and suspensions that contain flammable organic solvents. It combines a nitrogen (inert gas) system, a condensation system, and an explosion-proof system so the process gas circulates in a sealed loop rather than venting to open air.
Because the closed circuit keeps the drying environment isolated from atmospheric oxygen, the unit is intended for oxidizable and heat-sensitive materials such as biological products, enzyme preparations, and biological pesticides. Material is atomized into fine droplets and exposed to heat only briefly during spraying.
The system is aimed at universities, research institutes, and food, pharmaceutical, and chemical laboratories producing micro-particle powders in small batches.
A two-fluid nozzle atomizes the feed into a fine mist inside the drying chamber, where the droplets are heated instantly and converted to powder. The carrier gas runs in a sealed loop driven by the inert-gas and condensation systems, isolating organic solvent vapor from outside oxygen, while a cyclone separator collects the dried powder. Inlet and outlet air temperatures are regulated by real-time PID control.
