Made in China Jyg Series Hollow Blade Paddle Dryer/Food Waste Dryer for Coal Ash in Chemical Industry
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.
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.
Working Principle
steam or thermal oil injected in the rotary shafts and the hollow
blades.Wet sludge is fed into the paddle dryer machine by the screw
feeder or sludge pump, and then is heated indirectly by the heat
medium.New surface area is released continuously while the shafts
rotate so that hot soda ash gets cooled in a high thermal
efficiency.
Dry product is discharged through the discharge valve, while the dusty air is cleaned in the
cyclone dust collector.
