Organic fertilizer dryer, also known as drum dryer, is widely used in the production line of organic fertilizer powder in pig farms. Due to the large space occupied by wet pig manure during the stacking process, which is not conducive to environmental requirements, pig manure dryer is widely recognized by users. Due to the characteristics of pig manure, dryers can be divided into two types: one is a drum type conventional dryer, and the other is a dryer with a dispersing shaft. Choose and use according to the user’s raw materials.
Organic fertilizer dryer is a specialized drying equipment used to dry various poultry and livestock manure (such as pig manure, cow manure, chicken manure, duck manure, etc.).
The hot air of the organic fertilizer dryer mainly comes from the installation of a combustion engine in the combustion chamber (combustion media include coal, natural gas, methanol, biomass particles, etc.), using a co flow heating method. Therefore, the materials that need to be dried are pushed back by the spiral cutting plate from the feeding box and the feeding chute into the cylinder. Due to the inclined placement of the dryer, on one hand, the material flows towards the rear under the action of gravity and rotation, and on the other hand, the material is repeatedly picked up by the copying board, carried to the upper end and continuously sprinkled down, forming a uniform curtain inside the cylinder, fully exchanging heat with the hot air flow inside the cylinder. As the material is repeatedly sprinkled, the moisture contained is gradually dried, thus achieving the purpose of drying. After the material passes through the dryer, a cyclone dust collector is needed to collect the material carried in the gas. If the exhaust gas does not meet the emission requirements, it should also be discharged after passing through a bag filter or wet dust collector according to on-site needs.
The main workflow of the organic fertilizer dryer is that wet pig manure passes through the feeding machine and enters the drying drum. Through processes such as high temperature, deodorization, dust removal, and cooling, the wet pig manure is dried in one go to a moisture content below 10% (which can also be made according to customer requirements), ensuring the maximum utilization rate of dried pig manure.
