Double cone rotary vacuum dryer is a new type of dryer drying in one of the mixed -. The condenser, vacuum pump and drying system, vacuum drying device. SZG double cone rotary vacuum dryer for double cone rotating tank, tank in the vacuum state, the clamping sleeve is filled with steam or hot water heating, heat through the inner wall of the tank body contact with the wet material. Wet vapor evaporation materials after heat absorption, through the vacuum pump vacuum exhaust tube was removed. Because the vacuum in the tank body, and the rotary material constant up and down, and turning, the drying rate of materials, improving drying efficiency, achieve the purpose of uniform drying. (if not need solvent recovery, the condenser can not) double cone rotary vacuum dryer design is advanced, has the advantages of simple structure, easy cleaning, materials can be completely discharged, simple operation. Can reduce the labor intensity and improve the working environment. At the same time because the container itself rotates material also rotates but the wall of the material is not deposited, so the heat transfer coefficient is high, the drying rate, not only to save energy, and even drying of the material fully, good quality. Double cone rotary vacuum drying machine can be widely used in pharmaceutical, chemical, food, dyestuff industry drying. In conformity with the requirements of the "GMP".
Double cone rotary vacuum dryer features:
1, the container rotates continuously, to update the material heating surface
2, indirect heating, can not be polluted
3, high thermal efficiency, increased more than 2 times than the general oven
4, the container rotation speed can be adjusted in the range of 3-13rpm
5, temperature control temperature displayed by the digital display instrument
Double cone rotary vacuum dryer operation guide
1, check before driving:
A, open the double cone rotary vacuum dryer, vacuum pump, double conical vacuum dryer pipe joints, stuffing for leaks, inlet, outlet seal is good, a vacuum gauge response is a sensitive.
B, open cooling water valve check heat pipe joints, stuffing for leaks, the pressure gauge response is a sensitive.
C, check the double cone rotary vacuum drying machine electrical control cabinet for all instruments, button, indicator light is normal, check the grounding wire is good, there is no leakage, short circuit phenomenon.
D, in the bosom filled with grease, starting motor run empty, listening to the noise is normal, if not normal, should check out the source of the noise, and to exclude.
2, the need of dry materials into a container (powder, granular, small pulp material by vacuum feed), double conical vacuum dryer and then close feed hole. 3, close the vacuum valve, open the vacuum pump, the negative pressure in dry container (600 - 755 mmHg).
Start the motor 4, turn on the power switch, button, press work, dryer began to work.
5, the valve opening heat carrier, let the heat carrier into the drying container interlayer, according to the process of testing.
6, drying is completed, first turn off the heat carrier injection valve, and then to the interlayer cooling water, cooling to room temperature to be material, stop vacuum. Open exhaust vacuum valve, switch off hunger, double cone rotary vacuum dryer rotary, open hole cover material. |
