Conduct oil heat (steam) drying drum dryer belongs to indirect heating mode, the heat conduction oil or steam drying heat, this type of dryer has low energy consumption of drying, the safety drying process,the material is not affected by heat source pollution etc.,which are widely used in the biomass, food, feed, fertilizer, bad slag chemical industry, medicine, coal, mining and other small particles or weakly caking dry powder material.
Heat conduction oil steam drum dryer, mainly composed of tube type heat exchanger, heat sources in and out center pipe, rotary drum, feeding and discharger of the machine, induced draft fan, dust collecter and distribution cabinets.Wet material enters into the dryer, uniformly distributed in the roller feed plate and the column tube turning, with a full contact with hot conduction oil (steam) tube type heat exchanger, realizing heat transfer, mass transfer (110-250 ℃), constant temperature drying, water vaporization and scattered with the air emissions, gradually reduce the moisture from the material, the material has finished the drying process.
1. With the single rotary drum dryer of high mechanization degree,which resistance to overload ability, large processing capacity,it can be the characteristics of continuous operation.
2.Heating 300 ℃ conduction oil (or steam) in the dryer after heat exchange, low temperature heat conduction oil (condensate water) back into the heat conduction oil furnace (steam boiler) through reheating,with circulation use,and make full use of heat and no loss, drying energy consumption is lower than common dryers of 20-40%;
3. The heat conduction oil (steam) drying drum dryer belongs to indirect heating mode, do not contact directly material and heat source, drying process with closed operation,the material after drying is clean without any pollution;
4. 110-250 ℃ drying process temperature can adjust according to the material properties,which can be used in a downstream drying process,it also can use counterflow drying process,which belongs to the low temperature, constant temperature drying,which the material drying process is more secure;
5. Good structure and simple operation,the material through cylinder with small resistance,smooth running and easy operation.
6.Wide application range and good uniformity of product drying.
