Coffee roasting produces a complex mix of smoke, chaff and pungent odor. The Souniny Coffee Exhaust Purifier is purpose-built for this exhaust, matching popular roaster sizes from 2 to 10 kg capacity.
Product Overview
The Coffee Deodorization Series (KL-D-K10 to K40) is purpose-built for coffee roasters, removing both smoke (98%) and odor (90%) from roasting exhaust. Four sizes match 2 / 4 / 6 / 10 kg roasters with airflows of 800 / 1,000 / 1,200 / 1,500 m3/h, and a 100 mm (or 200 mm on K40) flange adapts to most roaster ducts. CE2 certified and configurable for 100 V / 50 Hz markets, the units follow the roaster airflow curve through each roast stage — from warm-up to first crack to cool-down — for clean, compliant discharge at every phase. This makes the Coffee Exhaust Purifier suitable for urban roasteries, cafe backrooms and production facilities alike.

Maintenance & Filter Care
The electrostatic precipitator cells should be cleaned at regular intervals based on cooking intensity and grease load. In typical commercial operation, periodic washing keeps purification efficiency at its rated level. For units with activated carbon deodorization modules, replace the carbon when odor breakthrough becomes noticeable.
We recommend establishing a preventive maintenance schedule tailored to your daily cooking volume. Souniny provides replacement cells, carbon cartridges and spare parts to keep your system running at peak performance. Contact our service team for guidance on setting up a maintenance plan.
Applications
Coffee roasteries of all sizes, from cafe-scale 2 kg drum roasters to 10 kg production machines, including urban locations with strict odor discharge limits.
