Rotary double cone vacuum dryer compact structure, smooth operation, easy to operate. Reduce labor intensity, save labor. Applicable to pharmaceutical, chemical, food, dyes, metallurgical powder and other industries powder granular materials drying.
Rotary double cone vacuum dryer drying principle is the jacket into the steam or hot water, the internal heating, heat through the internal wall conduction to the wet material, the wet material in the gasification, water vapor through the exhaust pipe is pumping Go, the tank is in a vacuum state, to speed up the material drying rate. Tank low-speed rotation, the material constantly up and down, inside and outside the replacement of heating surface, and ultimately achieve uniform drying purposes.
How to operate rotary double cone vacuum dryer? Jiayuan medicine based on years of production and sales experience, summed up as follows.
1, before the start check items are as follows:
A. Open the vacuum pump check, pipe connections, packing material is leaked, into the outlet seal is good, vacuum table reaction is sensitive.
B. Check the electronic control cabinet of the instrument, buttons, lights are normal, check the ground wire is good, with or without leakage, short circuit exists.
C. Open the cooling water valve to check the connection of the heat pipe, whether the packing material leaks, whether the pressure gauge reaction is sensitive.
D. In the arms filled with grease, start the motor empty car operation, listen to the noise is normal, if not normal, should check out the source of noise, and be excluded.
2, will need to dry material into the container (powder, small granular, slurry material using vacuum feed), and then close the feed hole cover.
3, close the vacuum valve, open the vacuum pump, so that the negative pressure inside the container (600 - 755 mmHg).
4, close the power switch, start the motor, press the work button, the dryer began to rotate work.
5, open the heating body valve, so that the heating medium into the dry container sandwich, according to process requirements test.
6, the material is dry, the first heat off the valve, and then into the sandwich into the cooling water, until the material cooled to room temperature, stop the vacuum. Open the row of vacuum valve, turn off the electricity, stop the dryer rotation, open the hole cover out of the material.
