Cone Vacuum rotary dryer
Outline
Our product SZG double cone rotary vacuum dryer is suitable for the drying of heat sensitive, low temperature, powdery or granular materials in chemical, pharmaceutical, food, pesticide industry.
Detailed description
Working principle:
SZG double cone rotary vacuum dryer is manufactured and inspected according to the JB20013-2004 《Double Cone Rotary Vacuum Dryer》. It is a double conical drum with jacket in which the steam or hot water flowing to heat the inner drum. Heat transfer through the liner to wet material, so that the wet material in solvent be vaporized. Low speed motor drives the tank rotary, by which material continuously go up and down and turn to replace heating surface. At the same time, solvent vapor is sucked out through the suction pipe, which accelerates the drying speed and eventually achieves the purpose of uniformly dry.

Feature:
1. It is dried under vacuum, so at low temperature it has high speed to dry, for which it is energy saving, high heat utilization rate, especially suitable for drying heat-sensitive materials and easily oxidized materials.
2. Closed drying, no leakage, no pollution, suitable for drying strong stimulation, noxious materials.
3. The material in the rotating mixing and drying, by which it can be dried to very low water content ( < 0.5% ), and the uniformity is good. So it is suitable for different materials.
4. Equipment has the advantages of compact structure, small area occupation, simple operation, and low labor intensity.

Configuration:
1.The drum: type1. all stainless steel and internal deflector (guiding plate) inside; Type2.stainless steel drum, jacket and shell made by Q235 steel painted, deflector inside; Type3.stainless steel drum, jacket made by Q235 steel painted, stainless steel shell, deflector inside; Type4. glass-lined drum, stainless steel shell or Q235 steel painted.
2. Transmission: ①gear drive; ②the chain wheel, chain transmission.
3. Seal: two types of rotary joints and mechanical seal, usually we use mechanical seal. For vacuum end we have patent product of anti-reverse suction one-way valve, please indicate in the contract if you need.
4. Electrical: if you have special requirements, the dryer can be equipped with explosion-proof automatic control device, explosion-proof motor; It can also be equipped with a transformer for your optional order.
5. Discharge valve:①general butterfly valve ②butterfly valve + easy blind plate ③ worm-gear butterfly valve lined with polychlorotrifluoroethylene (PCTFE)
6. Polishing: internal Ra≤0.45μ m; external Ra≤ 0.45μm or Ra ≤0.8μm.
7: Vacuum pipe: stainless steel pipe, or sintering pipe.

specification

Notice:
1. After installation, the shell should be firmly grounding to avoid the danger of static electricity.
2. The maximum load calculated with materials density P=0.6kg
3. If no special declared, the jacket pressure is 0.2Mpa (hot water)
