Equipment Overview
During the coffee roasting process, heating green beans causes white smoke (oil smoke) and odors due to Maillard reactions and other chemical changes, which can have a negative impact on the environment.
MOTOYAMA’s smoke and deodorization removal system effectively removes white smoke and odors generated during roasting by using catalytic oxidation.
The system adopted a metal honeycomb (MH) structure coated with a platinum catalyst, which deodorizes and eliminates volatile organic compounds (VOCs) and hydrocarbon-based odors at low temperatures (200–400 degC).
This low-temperature operation contributes to energy savings and reduced operation costs, while providing an environmentally friendly and safely for human.
Features of the Metal Honeycomb (MH)
- Achieving optimal processing at approximately 200–400degC, compared to traditional direct combustion methods (700–800degC).
- It is flameless, highly energy-efficient and energy-saving.
Fuel consumption is less than one-third. - No NOx Generation in the treated exhaust gas.
- High open-area ratio and low-pressure loss in gas processing.
- Available for regenerative cleaning (VOC Treatment Specifications).
- Compact and Durable Design

Principle of Catalytic Reaction
Combustible substances contained in oxygen-containing exhaust gas are oxidized and thermally decomposed at low temperatures in the presence of a catalyst, converting them into odorless and harmless substances.
CmH2n + O2 → mCO2 + nH2O + Q (Heat/Heat of Combustion)
