♧ Fry-Drying System ?

■ Process description

1. Sludge Storage Tank & feeding system.
- Sludge in the store tank is transferred to the reactor
with a pump or screw conveyor.

2. Reactor ( dryer).
- The sludge charged into the reactor is dispersed in the hot
oil by a high speed agitator (Temp: 130-150C).
-The moisture in the sludge is evaporated by the hot oil and
the moisture is turns into steam.
-The sludge whose moisture has been removed is discharge
to the outside by the conveyor.

3. Screen system.
- Fried sludge in the oil is seperated by oil and sludge in
the vibrator screen.

4. Pressing Unit.
-After screening, remove any remaining oil from sludge by pressing.

5. Condensing unit.
-when the moisture in the sludge becomes vapor and exits
to the outside, it is condensed by the heat exchanger.

6. Deodor Unit
- A trace amount of gas that can nit be condensed is
removed from the odor preventation facility.

7. Condensing Tank.
- The condensate removed from the heat excharger is sent
to the existing waste water treatment plant.

8. Oil Circulation Tank.
- After passing the screen, the oil is brought back into the reactor.
