Descriptions
Applicablefor drying or cooling of paste, particle, powder and slurry state of material,perform the process of drying, cooling, heating, sterilizing, reacting andcombustion under low temperature. The special stirring and heating transferringblade, makes high heat transferring efficiency, and provide self-cleaningfunction. The special chock shaped stirring and heat transferring blade hashigh heating efficiency and self-cleaning function of the heating transferringsurface.
Hollowchock shaped blades are concentrated on the hollow shaft. Heat media flowthrough the blade from the hollow shaft. The heat transferring area in theeffective volume is very high. The temperature range of heating media is -40 ℃ to 320 ℃ . Itmight be steam, or liquid state, such as steam, thermal oil etc. Indirectheating, there's no heat carried out by air. All heat is utilized for to dryingthe material except the lost of heat insulation layers. The surface of chockshaped blade has self-cleaning function. The relative movements of the productparticles and the chocked shaped surface might clean the material attached tothe chock shaped surface, so to keep the cleanliness of heat transferringsurface during working. The shell of hollow blade dryer is Ω shape. 2 or 4pieces of hollow stirring shaft are usually equipped in the shell. To avoid anyleakage of material, there're sealed terminal cover and top cover with theshell. The heat transferring media flow through the rotation connector,jacket's shell and hollow stirring shaft. To ensure best transferring effect,the hollow stirring shaft adopts different interior structure in accordancewith different heating media.
Features
1.The heat consumption of blade is low: No heat carried out by the air because ofindirect heating; there's no heat insulation layer with the exterior wall ofthe dryer. It consumes 1.2 kg of steam to evaporate 1kg of water for to dryingslurry state of material.
2.The cost of the blade dryer is low: The unit effective volume has very largeheat transferring surface, so the processing time is shorted, the size of theequipment becomes small. The building area and place are sharply decreased.
3.The range of material to be processed is wide: Heat sensitive material and thematerials to be processed under high temperature might be processed withdifferent heating media. The normal media are: steam, thermal oil, hot waterand chill water. It might be continuous or batch operation, widely used in manyareas.
4.The pollution is less: Without any carrying air, very few powder is carriedout. The solvent evaporated is very few, it easy to be processed. For thematerial that might cause pollution or the solvent to be recovered, it mightadopt sealed circulation.
5.The operation cost is low: 1hour/day.operator is enough for normal operation.Low stirring speed and reasonable structure, the worn amount is few, and themaintenance fee is low.
6.Steady operation: The material particles fully contact heat transferring surface,because of the special compressing and swell-stirring effect of the chockshaped blade. The difference of the temperature, humidity and mixing effect arevery small in the different axial area, so to ensure the stability of process.
