Experimental spray freeze dryerIt is a method of freezing water containing substances into a solid state, and then sublimating the water in the solid state into a gaseous state to remove the water and preserve the substance.
In the process of compressed air drying, the experimental spray freeze dryer makes the water in the compressed air separate out by reducing the temperature of the compressed air. The working principle of a freeze dryer (refrigerated dryer) is the same as that of a refrigerator. After the compressed air passes through the frozen compressed air pipeline, the temperature of the compressed air drops to the required temperature to meet the drying requirements.
Features of experimental spray freeze dryer:
1. Humanized design: Scientific and reasonable structural design, novel appearance, beautiful and generous, easy operation, maintenance and upkeep, easy installation (without foundation).
2. The machine refrigeration system and air system have been comprehensively and accurately calculated by experts based on the differences in different working conditions across the country, with a design parameter margin of over 20%.
3. Refrigeration compressor: High performance refrigeration compressors such as Panasonic, Gulun, Taikang, Meiyoule, etc. are used, which have low vibration, low noise, reliable performance, energy saving, and ensure the long service life of the whole machine. The protection level of the compressor is IP54.
4. Special heat exchange design can reduce the inlet temperature and increase the outlet air temperature, which can avoid water droplets in the pipeline and affect the production environment.
5. Multiple forms of control circuits (single, integrated, joint control, PLC, frequency conversion, etc.). Suitable for different users' choices.
6. Comprehensive intelligent protection device: specially designed for refrigerant high and low voltage protection, phase sequence and phase loss protection, ultra-low temperature protection, as well as automatic defrosting, automatic fault shutdown, automatic alarm, motor overheating protection and other protection functions.
7. The automatic drain is set as needed, with high water removal efficiency. Floating ball type and electronic timing can be selected and set according to the machine operating conditions.
8. The experimental spray freeze drying unit adopts the cyclone separator of *. It can separate condensed water from the air and prevent liquid moisture from being carried out by compressed air under various airflow conditions, maintaining operation and achieving the purpose of drying and removing water.
