Product Description

Paddle dryer is a kind of drying equipment which is used to dry various material such as sludge (sewage sludge, oil sludge, and chemical sludge), food residue, spent grains, powder, resin and chemicals etc. Now it has been used as popular drying equipment in many fields.
Features:
1. Compact structure: dryer size is minimized due to the high efficiency gained from the large heat transfer area released by the rotating shafts and the dryer jacket.
2. Various heat medium: thermal oil, steam, hot water can be used as the thermal medium to heat wet material.
3. Indirect heating: preventing the material from being polluted.
4. Suitable for various materials (whole feed field, chemical material, sludge, powder, solvent recovery)
  Closed-loop for solvent recovery (inert gas blanket for explosive material)
5. Continuous operation.
6. High evaporation capacity.
7. High thermal efficiency.
8. Negative pressure, no dust flying.
9. Easy maintenance.
Ancillary equipment
1. Feeding device: depending on different material. (generally screw conveyor or feeding pump)
2. Drought fan
3. Dust collector (can be cyclone or fabric dust collector)
4. Discharge valve.
5. Control system.

3.Russia: 2sets PD1000 paddle dryers(for oil sludge)
4.Israel: 1set PD900 paddle dryer(for chemical sludge)
5.Yugoslavia: 1 set PD800 paddle dryer(sodium carbonate)
Working principle
Thermal medium is injected in the rotary shafts and the dryer jacket. Wet material is fed into the paddle dryer by the feeding device, and then is heated by the heat conducted through the rotating shafts as well as the jacket.
New surface area is released continuously while the shafts rotate so that wet material gets dried in a high thermal efficiency.
Dry material is discharged through the discharge valve, while the evaporated moisture which entrains a certain amount of dust is cleaned in the cyclone dust collector or fabric dust collector.
