Chicken Manure Dryer, also known as paddle agitated rotary drum dryer, rake roller dryer, rotary rake drum dryer, and rotary paddle drum dryer. The machine has kept the ordinary drum advantages of the dryer, it is custom designed suit to the disadvantage of the moisture is more than 50% weak stick, sticking material drying, and the drum center "black hole" phenomenon lead to the unit area evaporation capacity is inefficiency and high fuel consumption etc. Increasing the high-speed rotation of the blade, strengthen the material grinding and decentralized function, and fill the drum center "black hole". The material surface area fully expanded, to maximize heat transfer between the material and drying air. Because of the material particles to minimize and the heat transfer evaporation rate greatly improved. After a large area of ​​production practice proved that chicken manure dryer compares with ordinary drum dryer. The unit area of ​​water evaporation capacity of 25-30kg water / m2 • h, which is 1-2 times the ordinary drum dryer. The output of same size drying Machine increased by 50% or more, and fuel energy consumption reduced by more than 30%. equipment spatial footprint is ​​smaller than 40%. The material moisture content dry more uniform, and more than 40% efficiency. The dryer is suitable for chicken manure, cow dung, feces organic fertilizer, sludge, bean dregs, starch residue, sauce residue, sprayed corn kernels, cassava residue, beer distiller's grains, lees, straw, pasture and other 50-85% moisture content of material Drying. All of our drying process technology according to the characteristics of each biomass material, the size of production, the application requirements, the cost control, the degree of automation, the site conditions etc.


Material flow is: 75-85% moisture content of the material fed into the special dehydration machine, the water removed to about 65% through the screw conveyor into the mixing drum dryer to downstream drying. Flights pick up material, carry it over, and shower it through the air stream as the drum rotates, promoting maximize efficiency of heat transfer between the material and drying air. The rapid evaporation of water vaporization, to achieve the effect of drying materials in the hot air under the rapid flow of the drum. The rotary drum dryer gives material a chance to dry before it hits the next flights, in order to prevent buildup near the wet material discharge. Drum cleaning device is installed inside of the drum to prevent the material sticking issue.
Air Stream Flow as Below:
The air through the air blower increase pressure into the hot air furnace to heating, when the temperature reached to 600-850℃, the hot air will be into dryer to drying wet material and evaporation water by induce draft fan. Through three-layer heat transfer, the air temperature reduces to 55-65℃ and then discharge from dryer. The dust and moisture are purified trough the cyclone dust collector and wet dust collector.
Flow Chart:


1. This chicken manure dryer can realize the automatic and intelligent control, the operation parameters can be automatic control, the dryer is always in the best condition to running, it can be ensure uniform drying out of the raw material moisture is stability.
2. The inside of chicken manure rotary dryer has the unique flights to hits and tumbling the materials. In order to maximize efficiency of heat transfer between the material and drying air. The output of equipment increase more than 50% and the fuel energy consumption decrease more than 30%.
3. This machine uses four-wheel drive assembly. The driving is more stable and reliable.
4.The spatial footprint of general rotary drum dryer less footprint about 40%. The civil investment reduced about 40%. The equipment cost decrease about 20%.
5.The internal structure of the dryer use various efficient flight patterns. It can efficiency adjust the feed and heat distribution. The high heat efficiency, waste are exhausted temperature is lower than 50 ℃.
6.Adopts frequency motor control the material flow, heat supply, and drum rotate speed. It can easily adjust according to the needs of the outlet material moisture content and equipment output.
7.This type dryer use the modular dust collector purifying and heat recycling assembly. It is safe and protect environmental.
8.The chicken manure dryer is several options for new type energy-saving hot air furnace, high efficiency and energy saving, heating can be control, simple operation, energy consumption decrease about 30%, power consumption reduce 20%, and lower operation costs.
