Coffee Roaster Exhaust Duct

Hoods and ducting can be used to capture the dust and prevent it from settling back into the drum.

Coffee roaster exhaust duct.

Tighten the three screws to fix the hot air fan and the cyclone chaff collector. Clean modern styling. Cyclone to afterburner ducting is included and the whole system will come pre mounted and wired for ease of installation. Coffee roasting is generally made up of numerous steps that require dust collection.

The diameter of the pipe is important but depends on a few factors. Hot air motor connection. Adjust the air outlet direction of the chaff collector. Contact nordfab for assistance with ducting for your coffee roasting application or to learn more about our solution.

Inside the venting this type of airflow is called positive pressure because the pressure inside the vent line is greater than the atmospheric pressure outside the line. Connect the main body of the coffee roaster with its green bean loading hopper. The blended coffee then goes to holding bins or to feed hoppers over the roasters. Any dust or chaff loosened by the mixing is removed by an exhaust system.

Any bends will also restrict airflow and the total distance of exhaust pipe is also a factor. Any exhaust ducting will increase the resistance to air movement and decrease overall air flow a little from the roaster. During this process coffee roasting creates unwanted byproducts from beans and natural gas combustion. There are really three stages to the coffee bean roasting process where ducting is needed to exhaust and extract particulate from the air.

Connect cyclone chaff collector with its hot air exhaust motor.

Clean stream afterburners reduce smoke odor emissions from commercial coffee roaster exhaust. The batch is mixed in a few minutes by helical flanges inside the blender.

Shown is a csa 400 cat catalytic oxidizer. When the beans are loaded into loaders and drums dust can bloom. Coffee roaster ducting coffee roasters are used to develop a chemical change by heating and preparing coffee beans for consumption. The initial roasting stage.

Standard nordfab duct is not designed for unexposed areas where double walled duct is required.
