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. (such as the solvent to be recovered, the condenser can not) this machine has advanced design, simple structure, easy cleaning, the material can be fully discharged, simple operation. Can reduce the labor intensity and improve the working environment. At the same time because the container itself rotary material material also rotates but the container does not accumulate material, the heat transfer coefficient is high, the drying rate are high, not only to save energy, and even drying of the material fully, good quality. In conformity with the requirements of the "GMP". Double cone rotary vacuum dryer uses:
Applicable to the pharmaceutical, food, chemical industries such as powder, granular material, vacuum drying and mixing, especially with the following requirements of material:
1, can not accept high temperature of heat sensitive materials; 2, easily oxidized, hazardous material; 3, the solvent to be recovered and toxic gas material; 4, the residual volatile matter content requirements of low material requirements; 5, sufficient mixing, homogeneous material.
The working principle of double cone rotary vacuum dryer:
The working principle of double cone rotary vacuum dryer:
Rotating tank SZG series double cone rotary vacuum dryer body has double cone liner, stainless steel or carbon steel glass lining (made of industrial enamel). The jacket into the hot water or steam, for the inner heating, heat conduction through the wall of the inner liner to wet material, make water wet gasification in material, water continuously through the suction pipe is removed, the tank body is in a vacuum state, to accelerate the drying rate. The low speed rotary, material continuously from top to bottom, and turning to replace the heating surface, finally achieve the uniform drying purpose.
Double cone rotary vacuum dryer body slightly as the olive shape, both ends of the cover is arranged in the middle of the two, to support the body. The body with a jacket to heating, drying device, rotary, material and wall replaced frequently contact, overcome material vacuum oven mainly depends on the heating cylinder conduction and low heat efficiency. Double cone rotary vacuum dryer in fine chemical industry, medicine and so on have been widely used in high viscosity, or during the rotation process strongly adhesive material is not applicable. Double cone rotary vacuum dryer is mainly used in pharmaceutical, chemical, food and other industries of powder, granular and fibrillar material concentration, mixing, drying and low temperature drying material (such as biochemical products), more suitable for easy oxidation, volatile, toxic materials, heat sensitive strong stimulation and does not allow the destruction of the crystal materials drying.
Double cone rotary vacuum dryer check before use:
1, must be checked before using the transmission system is in normal operation, each fastening part is fastened;
2, the parts of the lubrication is oil;
3, instrument machine, instrument, various types of pumps, the valve is normal;
4, 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;
5, check the various pipeline and water, liquid, steam should be smooth;
6, check the double cone rotary vacuum dryer control button is at the zero position;
7, if it is heated by steam to check the dryer drum jacket water is discharged, to close the bypass drained jacket water, open drain valve;
8, check the double cone rotary vacuum dryer drum outlet and a manhole is closed, the screws are tight;
9, check the double cone rotary vacuum dryer drum is clean in place, often check the dryer drum bag, is blocked, damaged, should be replaced promptly clean, to keep the vacuum;
10, check out the database tools are complete and clean;
11, start double cone rotary vacuum dryer, confirm equipment around unmanned, barrier free to start.以上结果由提供 |
