working principle:
Using nitrogen as the conductive heat transfer medium, it realizes the drying production and recovery of organic solvents and solvent materials in the fields of pharmaceuticals, biochemistry, chemical engineering, biology, etc., with practicality of safe production, high efficiency, low consumption, energy saving and emission reduction.

Equipment features:
1. Efficiency: The equipment is a fully enclosed structure with no dead corners. Both the outlet and inlet air are filtered with high temperature and efficiency. The entire system adopts three-stage dust removal, which has higher dust removal efficiency and is easy to disassemble and clean. This device complies with GMP requirements.
2. Safety: Based on the explosive and flammable safety hazards of organic solvents, this unit system adopts online oxygen measurement, overpressure relief, explosion prevention, and other safety technology measures. Through intelligent control technology, the monitoring of residual oxygen in the system, pressure balance monitoring, and automatic adjustment control are achieved.
3. Environmental Protection: This unit realizes the recycling and utilization of solvent containing materials in the drying production process. On the basis of solving the difficulties in drying and heavy pollution caused by exhaust gas emissions in related industries, it achieves solvent recycling and utilization while achieving zero emissions, avoiding the pollution of exhaust gas to the environment and achieving practical energy-saving and emission reduction effects.

The circulating air of the new intelligent closed circulation dryer has three levels (including high efficiency) of filtration, with a high degree of purification and minimal material accumulation in the pipeline. According to customer needs, vacuum feeding and discharging can be equipped to improve integrated intelligent operation.
