Expect moisture evaporation, the gasification of mitochondrial surface；Finally, material cools down through cooler, so that material particles shortcakeization；
Described powder drying means also includes：In the presence of Roots's water ring vacuum pump, vapours enters condensation in main tank body
Cooler；Air-flow passes through between the corrugated sheet that the multi-disc parallel spaced-apart in liquid blocker is set, and on the two sides of each corrugated sheet
The multiple end faces to distribute alternately be in hook-shaped blend stop in the presence of, air-flow produce cyclone；Solvent warp and corrugated sheet in air-flow
Condensed after contact, and enter recycling design tank from the leakage fluid dram of recycling design pot bottom；
The distributing device of front and rear vibration, the discharge end of the distributing device in the main tank body and when being provided with work below the feeding mouth
Lower section is provided with conveyer belt；Distributing device includes front and rear vibration and the dustpan body of inclined downward backward during a job；
Wherein, during feeding, in the presence of Roots's water ring vacuum pump, interior main tank body is in negative pressure state, and vacuum feeding tank connects institute
The control valve stated on the pipeline of main tank body is opened, you can make vacuum feeding tank feeding, while by the blow-down pipe of vacuum feeding tank
Atmospheric valve close, then by vacuum feeding tank inlet valve open and feeding；When inlet amount reaches preset value, described first
Sealing valve, inlet valve and control valve are closed, and then control the second sealing valve and atmospheric valve to open, because the inner chamber of granulator is in negative
Pressure condition, is in now normal pressure in vacuum feeding tank, and the material in vacuum feeding tank is quickly sucked granulator and carries out a machine, is made
After the completion of grain, the second sealing valve is closed successively, opens the first sealing valve, material plastochondria is fallen into distributing device.
