Sludge Paddle Dryer

What is the Sludge Paddle Dryer 

Machine Video Link: https://youtu.be/NODGF9dPf8Y

The sludge paddle dryer is a kind of low-speed agitating dryer with agitated pulp inside the equipment to make the wet material fully contact with the heat carrier and hot surface under the agitation of paddle, so as to achieve the purpose of drying. The structure is generally horizontal, biaxial or four axis.

The paddle dryer can indirectly heat or cool the paste, granular, powder and slurry materials, and can complete the unit operations of drying, cooling, heating, sterilization, reaction and low temperature combustion. The special wedge-shaped agitator blade has high heat transfer efficiency and self-cleaning function.

Work Principle

Hollow wedge shaped blades are concentrated on the hollow shaft. Heat media flow through the blade from the hollow shaft. The heat transferring area in the effective volume is very high. The temperature range of heating media is -40 ℃ to 320 ℃. It might be steam, or liquid state, such as steam, thermal oil etc. Indirect heating, there’s no heat carried out by air. All heat is utilized for to drying the material except the lost of heat insulation layers. The surface of wedge shaped blade has self-cleaning function. The relative movements of the product particles and the wedge shaped surface might clean the material attached to the wedge shaped surface, so to keep the cleanliness of heat transferring surface during working. The shell of hollow blade dryer is Ω shape. 2 or 4 pieces of hollow stirring shaft are usually equipped in the shell. To avoid any leakage of material, there’re sealed terminal cover and top cover with the shell. The heat transferring media flow through the rotation connector, jacket’s shell and hollow stirring shaft. To ensure best transferring effect, the hollow stirring shaft adopts different interior structure in accordance with different heating media.

Paddle Dryer Machine MAIN FEATURE

1. The cost of the blade dryer is low: The unit effective volume has very large heat transferring surface, so the processing time is shorted, the size of the equipment becomes small. The building area and place are sharply decreased.

2. The range of material to be processed is wide: Heat sensitive material and the materials to be processed under high temperature might be processed with different heating media. The normal media are: steam, thermal oil, hot water and chill water. It might be continuous or batch operation, widely used in many areas.

3. The pollution is less: Without any carrying air, very little powder is carried out. The solvent evaporated is very few, it easy to be processed. For the material that might cause pollution or the solvent to be recovered, it might adopt sealed circulation.

4. The operation cost is low: 1hour/day.operator is enough for normal operation. Low stirring speed and reasonable structure, the worn amount is few, and the maintenance fee is low.

5. Steady operation: The material particles fully contact heat transferring surface, because of the special compressing and swell-stirring effect of the wedge shaped blade. The difference of the temperature, humidity and mixing effect are very small in the different axial area, so to ensure the stability of process.

Paddle Dryer Machine KEY APLLICATION

Paddle Dryer Machine is successfully applied in foodstuff, chemical, petrochemical, dyestuff, and industrial mud etc. The heating transferring, cooling and stirring characters enable it to perform the following unit operation: combustion (low temperature), cooling, drying (recovery of solvent), heating (melting), reacting and sterilizing. The stirring blade is heat transferring surface too, so to increase heat transferring area of unit effective volume is increased, and decrease processing time. The wedge shaped heat transferring surface has self-cleaning function. Compressing and swell-stirring functions make the material mixed uniformly. The material performs the movement of "piston flow" along the shaft. The difference of the temperature, humidity and mixing effect are very small in the different axial area. The blade dryer is capable to perform combustion under low temperature if we adopt thermal oil as heating media, such as Ca Ca2SO4·2H2O is combusted into Ca2SO4·1/22H2O, NaHCO3 is combusted into Na2HCO3 and so on. It’s capable for cooling process with water and chill salted water etc, such as base cooling machine in Na 2CO 3 industry, instead of the old style base air cooler , so to save power and the processing equipment for tail air, and save operation cost. Drying is the main function of this machine. Drying without hot air makes the process of solvent recovery, energy consumption, and control of environment ideal, easy to teat. It’s especially applicable for recovery of solvent and heat sensitive material that is easy to be combusted or oxidized. It has been widely used in chemical, petrochemical, and dyestuff industries. The uniformity of temperature, humidity and mixing effect in axial areas make the equipment capable for heating and melting, or reaction of solid material. It’s successfully applied in mixed fertilizer and character transformed starch industries. The blade dryer is also capable for sterilizing food and starch. The big heating area in unit effective area, dry the material to sterilizing temperature very fast, so to avoid quality change caused by long time heating.
