Peat Rotary Dryer

Peat, also known as grass peat, peat soil, black soil, peat, it is all coal with the lowest degree of coalification, also the most primitive state of coal. Peat is formed in peat swamps, and than formed by the pressure of overlying sediments and further Under bacteriolysis conditions, the compaction and dehydration become more firm. Formed coal is sterile, non-toxic, non-polluting, good ventilation performance, light weight, water retention, fertilizer retention, beneficial to microbial activity, enhanced biological performance, abundant nutrition. It is not only a cultivation matrix but also a good soil conditioner and contains high organic matter, humic acid and nutrients. The organic matter in peat is mainly composed of cellulose, hemicellulose, lignin, humic acid, and asphalt materials. Peat has a wide range of uses, it can be used in agriculture, such as soil-based cultivation of organic fertilizers and seedlings and flower cultivation, and in industries such as power generation fuels and chemical raw materials. Because peat is composed of various organic compounds, protein feeds, biological growth agents and phytostimulating hormones. All above mentioned can be extracted from peat, and different types of adsorbents and pharmaceutical preparations can also be produced.


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.

Peat rotary dryer is special design for peat of high moisture, big viscosity, small density, low heat resistance, easy cluster, and other character development and market demand product. This peat drying system main included heating source, Break feed equipment, Belt feeding machine, rotary drum, discharge equipment, dust removal, belt discharging machine, induced draft fan, peat combustion, temperature control, power operation system and system structure.
The working principle of the dryer system as follows:
1.moisture content 35-60% peat by scattered feeder evenly into the dryer, in the process of drying, peat will pass six workspace: one is the feed zone, wet peat into this area with low-temperature hot air quickly evaporates moisture, the material in big Angle of copy board copy, In front of the binder will import to next workspace.
2. Second is repeatedly broken beat and cleaning area, equipment design in this area have broken beat cleaning device, wet peat grabbed by grating copy board broken beat, large wet slurry after repeated broken beat, broken knead into a 20-30 mm small particles of carbon, forming curtain material status, increase the heat exchange area, improve the drying rate, cleaning device reasonably clean wall adhesion of peat, prevent peat adhesive.
3. Three is the main drying area, through two area processing wet peat has a granular loose state of the material, in this area will be raising by inclined feed plate, the material will form a uniform state of material desire, and full contact with hot air to heat exchange, strong precipitation.
4. Four is pounding broken drying area, in this area peat after repeated pounding broken in this area, peat particles from 20-- 30 mm broken for 3-15mm size (as customer request), further reducing moisture content.
5. Five is strengthening drying region, through the broken small peat particles from the copy board raised area is densely populated, fully absorb hot heat, discharging water, achieved water standard, ready to discharge;
6. Six is discharging area, in order to prevent discharging dust, do not set a copy plate roller in this region, the slide material rolling to the discharge port to complete the whole drying process. Peat moisture content is 10-15%, 3-15 mm granular coal or organic fertilizer.


Peat rotary dryer Drying Principle 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. The flowchart of gas: the air is heated by the hot air furnace of draught fan and enter the hot air furnace to burn and get heated, the temperature reaches 600-850°C. After the dryer, the induced draft fan draws the material in the dryer to dry, evaporate water, pass the three-layer heat exchange, and the wind temperature reduced to 55-60°C and discharged from the dryer. The dust containing wet dust passes the cyclone dust collector and the wet dust collector gets to the emission standards.
