Why Need to process and dry chicken manure ?

Most of the people eat chicken egg and chicken meat, around the world there are countless chicken farm with small, medium, and large scale. The chicken farm generates chicken dung everyday, for example, 10 thousands layer hens can generate about 1,000kgs chicken manure per day. If not process the chicken manure rightly, not only it will pollute the environment, but also it is a waste of resource.

What is the use of dry chicken manure ?

As the short digestive tract of chicken, much of the nutrition is not absorbed by the chicken, and inside the chicken manure contains much N,P,K and organic materials. Research shows that there are 2.6%  nitrogen, 3.5% phosphorus, 2.5% potassium, 16-25% crude protein and 45% organic matters in the pure dry chicken manure.

Organic Fertlizer: It not only can supply the necessary nutrition for the plant growing, but also it can improve soil quality.  It is popular for the production of economical crops such as Organic food, Flowers, etc.

Animal Feed:  As additive of animal feed for pig, fish, etc.

Biomass Fuel:  As fuel for gasification furnace for the power plant.

How to process and dry wet chicken manure ?

For drying the chicken manure, the chicken manure dryer with reasonable design is necessary.

Sunco Machinery have participated in the design and manufacture of the drying machine for chicken manure since the year 2006. Combined with the past years’  practical experience, according to the special features of chicken manure, Sunco Machinery have developed the advanced and proven chicken manure drying system.

After being dried, the moisture content of chicken manure can be reduced to be about 13-15% or as need from 70-75%. What is more, not only harmful bacterial and worms are killed, but also the odor of manure is lighten much significantly.

The dry chicken manure can be directly used as organic fertilizer for the crops. You also can make the dry chicken manure into organic fertilizer pellets, and then pack it into bags. To do it in this way, not only the organic fertilizer pellets looks beautiful, but also you can sell it with better price in the market.

How to design the reasonable chicken manure dryer ?

First of all, have to fully understand the main features of wet chicken manure as follows:
(1) High Humidity up to about 75% moisture content;
(2) Sticky and easy to become lump type;
(3) The water is inside the wet manure but not surface water, the inner water is difficult to be got rid of. If the dryer system is not designed reasonably, after drying when the manure come out of the dryer, the surface of the manure seems dry, but the inner of the manure is still wet. After you store the manure some time, the inner water will come to the surface of the manure, and then the manure will become wet again.
(4) With strong smell especially in high temperature.

Secondly, key points to design the chicken manure dryer machine:
(1) The dryer machine should have related special device and reasonable structure to disperse the wet manure and increase the contact area between high temperature air and wet manure, and avoid the wet manure to adhere onto the inner wall of the dryer, and can have higher heat exchanging efficiency.
(2) The dryer machine’s diameter and length should be selected according to the needed capacity. Too small and too big both are not good.
(3) The dryer machine should can supply enough drying space and drying time for the wet chicken manure.
(4) The dryer system should have related device to process the smell of exhaust air.
(5) Hot air furnace should be designed according to the features of the fuel so that it can have good burning efficiency, easy for operation, and durable.

What is working principle of Sunco Machinery chicken manure dryer machine ?


Sunco Machinery chicken manure dryer machine is to use high temperature air to heat and dry the fresh chicken manure directly. Inside the chicken manure dryer, there are special lifting plates and crushing device which helps to disperse the wet chicken manure, so that there is enough contact area between the hot air and wet manure, and the wet chicken manure can be heated sufficiently, then the water is evaporated into vapor, and the chicken manure moisture content is reduced to be 13-15% or as need.

What is the work flow of one whole set of chicken manure drying system ?

(01) Hot Air Furnace is to generate and supply the high temperature air for the chicken manure drying system.
(02) Tractor Shovel put the wet chicken manure into Mechanical Feeding Hopper.
(03) Mechanical Feeding Hopper sends the wet chicken manure into inlet screw conveyor.
(04) Inlet Screw Conveyor sends the wet chicken manure into the Special Designed Rotary Dryer.
(05) Inside the dryer machine, the wet chicken manure is heated and dried by high temperature air sufficiently, and the moisture content of the chicken manure is reduced to be about 15% or as need.

(06) Draft fan is used to make high temperature air into the drying machine, after heat exchanging process in the dryer, makes water vapor and exhaust air out of the chicken manure dryer cylinder, and then goes into cyclone dust separator.
(07) After being dried, wet chicken manure become dry manure, most of dry chicken manure come out from the outlet of the chicken manure dryer machine, and some fine chicken manure powder is mixed with the exhaust air, and then goes into cyclone separator. Cyclone separator is used to separate the dry chicken manure powder from water vapor and exhaust air. Finally the water vapor and exhaust air come out from the top of cyclone separator, and then goes into deodorization tower; the fine dry chicken manure powder falls down to the bottom of cyclone separator, and come out through wind closing device.
(08) Belt Conveyor takes the dry chicken manure away from the dryer machine, and send it into pellet mill.
(09) Pellet Mill makes the chicken manure into pellets.
(10) Belt Conveyor takes away the chicken manure pellets from the pellet mill.
(11) Deodorization Tower and Condenser are mainly used to get rid of the strong smell inside the exhaust air, and finally the water vapor become water, and the exhaust air goes into atmosphere through chimney.
(12) Electric Control Cabinet is used to control all the machines in the chicken manure drying system.

What necessary information are needed for design and suggest suitable chicken manure drying machine ?

(01) Do you need to dry the fresh chicken manure or compost/fermented chicken manure ?

(02) What is the usual initial moisture content (%) of the wet chicken manure ?

(03) After drying, what is the needed output moisture content (%) of the dry chicken manure ?

(04) How many tons wet chicken manure do you need to process and dry per hour ?

(05) Regarding to the heat source, what kind of fuel will you prefer to use such as coal, waste wood, diesel, or natural gas, etc ?
