Vacuum drying _ _ Jiang Yin Jiayuan medicated leather vacuum drying

Jiang Yin Jiayuan drug Equipment Co., square vacuum dryer has the characteristics of the material is heated evenly; efficient use of water-cooled trap capture, high-efficiency radiant heating devices. And to achieve rapid defrosting; Efficient vacuum unit, and to achieve oil-water separator; in parallel centralized cooling system, multi-channel on-demand cooling, working conditions stable, enabling energy conservation; using artificial intelligence control, control of high precision, easy to operate. The quality of freeze-dried products are biologically active constant appearance of uniform color, shape plump, firm structure, fast dissolving, the remaining water is low. To obtain high-quality products, freeze-dried theory and technology should be a more comprehensive solution. Jiang 阴嘉源 drug equipment Limited square vacuum drier samples require pre-cooled to at least -40 ℃, it can be carried out at cryogenic freezer (-70 ℃) or liquid nitrogen (-196 ℃) in. Open the sealed tube switch, move away freezing compartment, placing the sample on the frozen cabin bulkhead. Close glands switch. Then open square vacuum dryer switch off, wait 20 to 30 minutes until the temperature is below freezing compartment -40 ℃. Based on experience / dissolved in the amount of recovered coal / temperature conditions, the tank material drying in the confirmation process has ended, cutting off steam (or hot water) and the vacuum line valve, then slowly through the jacket cooling water, Once the material is cooled to a suitable temperature, press the stop button on the host, and use the jog buttons, let the tank go to the desired angle. Close the vacuum pump, open the vacuum line valve, open the vent valve on the vacuum system is turned on so that the tank atmosphere. To play an open manhole cover material discharge, and then clean the tank residual materials, close the discharge hole cover to prevent dust from entering the double cone vacuum dryer tank.
