Energy saving Hallow Dryer industrial dryer for sludge drying
Sludge Drying Industrial Drying Equipment Energy Saving Hollow Dryer JYG Series

APPLICATION
The blade dryer 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 chock 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

DESCRIPTION
There are hot air style and transfer style two styles. The drying in hot air style is completed through connection of hot air and material. In transfer style, material is connected with hot surface to drying, it can prevent pollution of material. The air outlet is few, efficiency is high, small size, save energy and prevent pollution of air.

FEATURES
1. The heat consumption of blade is low;
2. The cost of the blade dryer is low;
3. The range of material to be processed is wide;
4. The pollution is less: Without any carrying air, very few powder is carried out;
5. The operation cost is low;
6. Steady operation: The material particles fully contact heat transferring surface, because of the special compressing and swell-stirring effect of the chock 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.

WORKING PRINCIPLE
Energy saving Hallow Dryer industrial dryer for sludge drying has a metal wall which separates the process mass from the heat source (steam or hot oil). High thermal efficiency is obtained because the heat from the thermal medium goes directly into the process mass. As the material comes into contact with the heated through and agitators, the process mass is heated via conduction. With an insulated dryer, very little heat is lost. To evaporate 1kg of water only requires about 1.2kg of steam for slurry materials. Exhaust gas is minimal and at a low temperature. Therefore, the volume of non-condensable gas from the dryer, which might require treatment, is minimal.
