Chicken manure dryer Features:

Chicken manure dryer is a low-fuel-consumption and high efficiency of drying equipment. It can be be used to dry the material with a moisture content below 85% to a final moisture content below 13%,. It is applicable in animal farming, food brewing, sugar and pharmaceutical industries dealing with high humidity waste, as well as a variety of chemical raw materials, such as chicken manure, wine slot, furnace slag, fructose slag, slag vinegar sauce, sugar beet residue, animals slaughtered contents,  coal slime, bentonite, etc. It is for resource development and good environmental protection equipment.
The equipment uses downstream drying process, especially suitable for fast drying the humidity materials which need to preserve nutrition, for example, the drying of fresh chicken manure can achieve the purposes of  drying, sterilization, deodorant and preservation of nutritional. The dryer is equipped with high-speed rotating drum of crushing devices, which increases the contact area between material and drying medium, the internal unique equipment design, makes materials difficult to adhere to the drum wall panels and parade. The complete machine has the effects of heat preservation, good sealing performance, and the fact that the thermal efficiency considerably higher than the general drum dryer.
The dryer structure is compact, easy to install and debug, and using small floor area. Drum and crushing device use stepless speed regulating devices, which can adapt to the different requirements of the drying materials. The dryer can combine th use of different fuels (such as coal, heavy oil, natural gas, etc.).


Working principle
 
The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency.

Main Advantages of Chicken Manure Dryer:  
 
(1) High degree of mechanization with large capacity.
(2) Simple and excellent structure, material running smoothly through the cylinder.
(3) Less mechanical failure, low fuel consumption and easily operate.
(4) Achieving best drying effect within short time & low drying cost.
(5) New type of feeding, discharging device, put an end to the dryer feeding jams, no connection, material returning phenomenon.
