Cow dung dryer machine is Dingli company according to the market demand professional design and developed one type new rotary dryer,this new type dryer suitable to drying the material moisture content at 50-65%,such as cow dung,chicken manure, poultry manure,sawdust,wood powder,wood chips,wood shaving,barley straw,oat straw, wheat straw,rye straw,rice straw, broom corn straw,The peanut vine,corn straw and other material.Depended on the different characteristic of each type of raw materials, different capacity, application requirements, cost control, automation degree, optimize the drying process technology,working conditions on site and other things,we can design the drying process.Dingli Company recommended product:this cow dung rotary drum dryer unit capacity is larger,high efficient,saving energy,covers area is more less, it can saving energy more than 50% than ordinary dryer,it can maximize saving energy and drying costs.


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.
