subject: New Designed Energy Saving Rotary Dryer [print this page] First, the scope of energy saving rotary dryer application
Energy-saving telescopic dryer is an energy efficient improvement on the basis of the original humidity drying machine, drying equipment through continuous improvement and has now reached the advanced international level, not only capable of handling high-viscosity lower moisture materials, also is capable of handling sticky high moisture material. The machine is suitable for drying, moisture content of less than 85% of all types of bad residue materials such as grains, alcohol, bad, Marc, the dregs, butter bad,sugar residue, starch residue, manure, slaughter waste, with good results open up the feed resources, reduce feeding costs, reduce environmental pollution.
Second, the mechanical structure and working principle
Material by feeding device into the lining of the rotary drum, achieve the downstream drying, and the material in the inner shoveling plate are continuous brought up and down, scattered as spiral marching to achieve heat exchange, movement of materials to the inner layer of the other end into the middle for countercurrent drying. Material in the middle both fully absorb the heat of the inner drum ,also absorb the heat of the middle roller, which prolong dry time, and the material to achieve the best dry state. Material from the middle to the other end , fall into the outer layer of material. Material in the outer drum as rectangular multi-loop is marching . Material thatachieve the drying effect is discharged of roller under the effect of the hot air, while wet material that dose not reach the drying effect , due to its weight, can not fast march, and then the material within this rectangle copy board are fully dry, thus completing the drying purpose.
Three, three-cylinder two advantages, one big disadvantage:
1. under the same production, the three-drum dryer has small footprint, transport, easy to install;
2. heat exchange: materials and hot air is high downstream, countercurrent, downstream reciprocating cross to achieve the heat exchanger, heat exchanger for a long time, the water discharged in the inner drum, material evaporation, direct fan siphoned energy utilization efficiency .
3. If internal copy board is damaged, repair is extremely inconvenient.
