The Hollow Paddle Dryer 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.
1. Continuously drying of sewage sludge, animal manures and industrial sludges;
2. Heating area: 3-200 M2
3. Drying capacity: 50-5000 kg/h
4. Vapor tight or vacuum designs are available
5. Heat source: steam, hot water or hot oil
HEAT SOURCES(Temperature at 180ºC - 250ºC)
Heating by Steam
Steam enters the hollow shaft through a rotary joint and is evenly distributed to all paddles. Condensate is removed with each revolution.
Heating by Hot Oil(thermal fluid)
Hot oil(thermal fluid) enters and exits the hollow shaft through a rotary joint. Pressure from the supply pump forces liquid through the hollow paddles.
Product Application
• The materials from such as the medicine t food , chemical industry, etc. can be dried.
• Suitable for pulpiness, paste-like mixture or power raw material.
• Temperature sensing material requiring the low temperature to be dried.
• Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
• Demand to retrieve of the organic solvent.
