Dr.Air CF-4000 Coffee Roasters Smoke Treatment System

The smoke filter of Dr.Air CF-4000 is specially developed for coffee roasters. All dust particles, soot, … are removed to the maximum, keeping the space clean, friendly with the environment.

Principle Of The Coffee Roaster Smoke Treatment System By Electrostatic Filter Technology

Exhaust gas is put into the treatment system, passing through the elementary filter chamber to filter out coarse dust and grease before entering the high-voltage ionization environment. In this environment, the smoke of coffee roaster, oil, and soot are ionized (electric charge infect stage), turning into charged particles. Particles continue to enter between collector plates that have opposite charges, due to opposite electrostatic attraction or Coulomb force, charged particles are trapped on the collector plate.
