Hollow paddle Dryer (Sludge Drying Machine)
is a horizontal stirring and heat conduction type Equipamento de secagem that can work continuously. Its stirring blade is like ship paddle, so it is called paddle dryer. In foreign countries, it is also called slot dryer or stirring dryer.
Hollow paddle dryer is successfully used in foodstuff, químico, petrochemical, corante, industry sludge fields, etc.. The characters of heat transfer, resfriamento, and stirring make the machine can achieve the following operation: Calcination (low temperature), resfriamento, drying (solvent recovery), heating (melting), reaction and sterilization. Stirring paddle is heat transfer surface as well, it makes the unit efficient heat transfer area larger, and handling time is reduced. Heat transfer surface of wedge type has slef-cleaning function. Compress—expand stirring function makes the material mixed uniformly. Material makes piston flow movement along the axial direction, in the axial direction interval, the temperature, humidity and mixedness gradient is very low.
