Double cone rotary vacuum dryer widely used in biochemistry, chemical pharmaceutical, medical and health, agricultural research, environmental protection and other research fields, for dry powder, baking and all kinds of glass containers disinfection and sterilization with. Particularly suitable for fast and efficient drying process for drying heat sensitive, easily decomposed, easily oxidized substance and complexity of the component items. Do you know how to operate? In the step of what needs attention.
1, add the workpiece to gas is pumped to workpiece material can be pumped to the composition of vacuum rake vacuum dryer vacuum drying box. If the first heating, gas heat expands. Because the vacuum box seal is very good, great pressure expansion generated gas may make the observation window glass burst. This is a potentially dangerous. According to the first vacuum and heating heating operation procedures, you can avoid the danger.
2, if the operation procedures according to the first heating and vacuum pumping, heating air vacuum pump out of the heat, will be brought to the vacuum pump up, resulting in high temperature vacuum pump, vacuum pump efficiency is likely to decline.
The 3 gas, heated by guiding the vacuum pressure gauge, will produce a temperature rise of the vacuum pressure gauge. If the temperature exceeds the vacuum pressure gauge using the specified temperature range, may make the vacuum pressure shown value error table.
Double cone rotary vacuum dryer design is advanced, has the advantages of simple structure, easy cleaning, the material can be fully discharged, simple operation. Dry sealed, no leakage, no pollution, suitable for a strong stimulus, poison material drying. The material in the rotating drying the mixture, material can be dried to a moisture content is very low (< 0.5%), and the uniformity is good, suitable for different material requirements. Zhuozhou talent net double cone rotary vacuum dryer has the advantages of compact structure, small occupation area, simple operation, reduce the labor intensity, labor saving. The user can choose the stepless speed regulation (1-10 RPM) and control (6-10 /), for rapid drying capacity and meet different requirements.
Double cone rotary vacuum drying machine applicable to the pharmaceutical, food, chemical industries such as powder, granular material, vacuum drying and mixing, especially with the following requirements of material:
1 could not accept the heat sensitive materials at high temperature;
2 easy oxidation, hazardous materials;
3 the solvent to be recovered and toxic gas material;
4 very low residual volatile matter content material;
5 for fully mixing, homogeneous material.
1) viscosity with the viscosity material double cone rotary vacuum dryer material moisture and viscosity changes, can cause the material to be reunited into blocks, and the adhesion of cylinder wall, dry and easy adhesion in the dust collector and the pipe wall. The pneumatic shock and crushing device.
2) allowable temperature of materials. Allowable temperature is the highest temperature in the material can withstand. Over this temperature, will lead to material change, damage or discoloration decomposition titer.
3) bulk density per unit volume of the material quality of the material known as bulk density. Because the material is dry mixture material with moisture, dry material often for granular, powder or solid bulk material, and with the material moisture in different cause dry gap between particles are also different. There is a great difference between the bulk density material for the original wet material and drying process, selection of rake vacuum dryer should be noted.
4) material slip angle stacked granular or powdery material, when the material pile inclined plane and the bottom angle increases to a certain point of time, there will be side material sliding phenomenon. The angle between the inclined plane and the bottom surface of the material that the material slide slip angle. Slip angle and the material composition, moisture content, particle size and viscosity of. Double cone dryer can slip angle, reference material, selection of cone angle. |
