Double cone rotary vacuum dryer is widely used in biochemistry, chemical pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research fields, dry powder, baking and disinfection and sterilization of various glass containers. Especially suitable for fast and efficient drying process for drying heating device items sensitive, easily decomposed, easily oxidized substances and complexity. Do you know how to do it? In what needs to be noted.
1. The gas added to the workpiece is pumped to the workpiece and the material can be pumped to the composition of the vacuum SZG series double cone rotary vacuum dryer vacuum drying box. If heated first, the gas thermally expands. Since the vacuum box is so well sealed, the gas generated by the high pressure expansion may burst the glass of the viewing window. This is a potential danger. According to the program of the first vacuum and heating heating operation, the danger can be avoided.
2. If the operation procedure is based on the first heating and vacuuming, the heat from the heated air vacuum pump will be brought out to the vacuum pump, resulting in a high temperature vacuum pump, and the vacuum pump efficiency may decrease.
3. The gas is heated by guiding the vacuum pressure gauge, which will cause the temperature of the vacuum pressure gauge to rise. If the temperature within the specified temperature range exceeds the vacuum pressure gauge, the indicated value of the vacuum pressure may deviate from the table.
The shell shape of the double cone rotary vacuum dryer is processed by high-strength electrostatic spraying, the steel plate is punched, bent, welded, and the film on the surface of the shell is flat and firm.
