Small sludge dryer, also known as sludge dryer, is a drying equipment specifically designed for drying sludge. Sludge dryer (sludge drying equipment) can be widely used for drying activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, tannery sludge, electroplating sludge, municipal sludge, biological fermentation bacterial residue, and other high humidity materials.

　　The dried sludge is quantitatively and continuously fed into the feeding port of the dryer by the screw feeder. The sludge enters the inner wall thickness and is flipped and stirred by the rotation of the blades, continuously updating the heating interface. The sludge directly contacts the inner wall, blades, and shaft to improve thermal efficiency and evaporate the surface moisture contained in the sludge. At the same time, the sludge is transported in a spiral trajectory towards the discharge port with the rotation of the impeller shaft. During the transportation, it continues to be stirred, allowing the water seeping out of the sludge to continue to evaporate. Qualified products that are evenly dried are discharged from the discharge port.

　　What are the advantages and characteristics of small sludge dryers?

　　1. Dry evenly. Equipped with a baking room design and uniform air ducts, it can evenly heat the Buddha fragrance and bake good products.

　　2. Energy saving. Heat pump dryers absorb heat from the air to dry materials, consuming very little electricity. Moreover, the new generation of dryers has been fully upgraded with secondary waste heat recovery, resulting in better energy efficiency and less heat loss. The air inside the furnace and corresponding containers do not dissipate heat, resulting in high thermal efficiency and significantly improved production environment.

　　3. Easy to control. Compared with conventional methods, the operation is simple and convenient; The temperature and humidity in the baking room can be adjusted.

　　4. Good drying quality of materials. The closed cycle of drying media can avoid impurities and pollution that may be caused by the exchange of external gases, which is particularly important for food, medicine, or biological products.

　　5. No pollution. During the drying process of a small sludge dryer, the drying medium is enclosed in a closed loop, without the pollution caused by material dust, volatile substances, and odors emitted into the environment with the drying exhaust gas; The waste heat in the exhaust of the drying room is directly recovered by the heat pump to heat the cold and dry air, without causing thermal pollution to the environment by the unit.
