Application:grass peat, peat soil, black soil, peat
Peat roller dryer, also known as paddle-rotary drum dryer, rabble-type rotary drum dryer, rotary rake dryer, rotating paddle drum dryer, the machine is to retain the ordinary roller. Based on the advantages of the dryer, it can not be adapted more than 50% moisture, weak adhesion, drying of adhesive materials, and the disadvantage of low evaporation per unit area and high fuel consumption due to the phenomenon of “black hole” in the center of the drum. Increasing stirring high-speed rotating blades, increasing the crushing and dispersing function of the material, fill the center of the drum "black hole", the material surface area fully expanded, and fully contact with the hot air to evaporate the material moisture, because the material particles are minimized, heat transfer evaporation water velocity raised dramatically. After many of production practice result proveded, that the peat drum dryer than ordinary drum dryer, water evaporation capacity per unit area of 25-60kg water / m2 · h, is 1-2 times the ordinary drum dryer, the same size drying Machine capacity increased by more than 50%, fuel energy consumption was reduced by more than 30%, equipment occupied an area of more than 40%, and moisture content of the dried material was more uniform and efficiency increased by more than 40%. It is suitable for peat, sludge, bean dregs, starch slag, sauce residue, spray corn husk, cassava slag, brewer's grains, distillers' grain, straw, grass, organic fertilizer, chicken cow dung and other moisture about 50-85% high humidity material drying. The company can optimize the drying process technology design according to the characteristics of each biomass material, output size, application requirements, cost control, degree of automation, on-site conditions.
The flowchart of material: Moisture content is about 50-65% and peat is fed by a screw conveyor into a rotary drum dryer to achieve downstream drying. The materials are continuously picked up and scattered under the copying board, and the materials are scattered and spirally advanced. The inner of dryer has stirring blade device will make the material fully stirred, break up and beat, and the material and the hot gas are fully in heat exchange. The moisture quickly evaporates and vaporizes. The material that achieves the drying effect quickly moves out of the drum under the action of hot air. The wet material that does not reach the drying effect that cannot travel fast due to its own weight, and the material inside of the drum is fully dried to achieve a drying effect, and the drying process is completed and discharged from the screw conveyor. Inside the drum has a shock cleaning device to prevent material sticking to the wall.
