Stainless Steel Rotary Dryer With Electric Heating

‌Product Introduction‌
This direct heating stainless steel rotary dryer is a high-efficiency continuous drying equipment that adopts the direct hot air contact heating mode and full stainless steel rotary drum structure. All parts in direct contact with materials are made of high-quality 304/316L stainless steel, with no heavy metal precipitation, no material residue, and the direct heating mode features high thermal efficiency, fast drying speed and large processing capacity. It can stably adapt to the long-term continuous drying of various non-viscous, non-easy-oxidizing high-moisture granular and powdery materials, fully meeting the strict standards of mining, new energy, chemical and environmental protection industries. It is the core drying equipment to ensure no material pollution, uniform moisture and ultra-high thermal efficiency in modern large-scale industrial production lines.

‌Working Principle‌
The obliquely installed fully enclosed stainless steel multi-cylinder insulation main body is driven by a high-torque heavy-duty transmission system to rotate at a uniform low speed. The high-temperature clean hot air generated by the heat source directly enters the inner cylinder at high speed and flows in the same direction or countercurrently with the materials. High-moisture materials to be dried are fed into the inner cylinder through a sealed anti-blocking feeding port, and the built-in wear-resistant anti-sticking stainless steel lifting plates continuously lift and scatter the materials as the drum rotates, making the materials fully dispersed and in direct full contact with the high-temperature hot air flow. Free moisture in the materials is efficiently and quickly evaporated in an instant, and the dried finished products that meet the industry moisture standards are stably discharged from the special anti-caking discharging end, completing the continuous direct heating drying process. The all-stainless-steel material contact system will not be corroded or abraded by materials, completely avoiding hidden dangers such as material pollution, equipment perforation and low heat utilization rate.

‌Core Features‌
This equipment has multiple exclusive advantages of direct heating stainless steel drying. The direct hot air full contact heating mode makes the thermal efficiency as high as 92%, which is 30% higher than that of indirect heating dryers, and the drying speed is extremely fast. The full stainless steel drum has excellent anti-corrosion and anti-wear performance, and the service life is more than 2 times that of ordinary carbon steel direct heating dryers. The hot air temperature can be adjusted steplessly from 60℃ to 900℃ according to material properties, which can meet the drying requirements of most industrial materials. It can be customized with different daily processing capacities from 10 tons to 1500 tons according to the actual material properties and large-scale production scale of users.
