  With the acceleration of social and economic development and urbanization, the amount of sewage sludge in urban areas is increasing. Like domestic garbage, if it cannot be disposed of safely, it will seriously affect the living environment. The effective means of sewage treatment is to press and dewater the sewage, and then dry the sludge. The volume of the dried sludge can be reduced by 4 to 5 times. The product is odorless and free of pathogens. It can be used as fertilizer, soil improver and substitute energy, etc.

  According to the characteristics of sludge treatment at present, Jiutian Machinery has carried out a series of technical breakthroughs and practices, and carefully developed a horizontal stirring continuous drying equipment with steam as heat transfer medium and heat conduction as the main part. Because the agitating blade is shaped like a paddle, it is called a paddle dryer. The product can indirectly heat or cool the paste, granular, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low temperature combustion. The special wedge-type stirring heat transfer blades in the equipment have high heat transfer efficiency and self-cleaning function of the heat transfer surface.
