Main features:
 
1, 7-inch touch screen operation control, full Chinese operation interface, heating temperature PID constant temperature control, can directly set the inlet temperature, air flow,
 
Automatic needle frequency, pump speed, data acquisition and process monitoring and control, using full-automatic control and manual control dual control mode, the whole experimental process dynamic display by color touch screen (animation)
 
2, the self-priming peristaltic pump enters the sample liquid from the container into the drying chamber through the nozzle, At the same time, compressed nitrogen enters the drying chamber from the outer sleeve to micronize the liquid, The heated nitrogen enters from the upper layer and meets the sprayed liquid particles, and the articles begin to dry. The dried powder particles are separated from the waste gas by the cyclone separator and then enter the collection bottle. The airflow carrying organic vapor is cooled down in the heat exchanger, then the solvent is condensed and recovered in the refrigeration device, and the clean nitrogen enters the next cycle.
 
3. The inert gas closed cycle laboratory spray dryer will seal these toxic gases in the system and collect them in the later working procedure, which can reduce environmental pollution and be beneficial to environmental protection. Avoid poisoning gas pollution in raw material production.
 
4. The explosion-proof closed laboratory spray dryer can circulate the materials in the closed drying system, which can avoid the contact between organic solvent gas and external oxygen air, ensure the safe production, and effectively solve the problem that the organic solvent materials are flammable and explosive and difficult to dry
 
5. The materials are dried and transported in the oxidation-resistant environment of the closed-circuit circulation system, which plays the purpose of isolating from oxygen and ensures the quality of drying and production of easily oxidized materials;
 
6. During the experiment, the spray head of Chuanyi instrument is not eccentric during atomization, and will not spray on the bottle wall during spraying, which will affect the recovery rate. The spray head can move up and down to change the atomization position to improve the spray drying effect; The spray head has very good adaptability to high viscosity materials, and the phenomenon of blocking the spray head rarely occurs;
 
7. The standard tail gas dust removal device reduces environmental pollution, effectively improves the yield and improves the yield of materials that are not easy to recover;
