Coffee Roaster Exhaust Duct

Coffee roasting is generally made up of numerous steps that require dust collection.

Coffee roaster exhaust duct. Coffee roaster ducting coffee roasters are used to develop a chemical change by heating and preparing coffee beans for consumption. The batch is mixed in a few minutes by helical flanges inside the blender. The diameter of the pipe is important but depends on a few factors. Any bends will also restrict airflow and the total distance of exhaust pipe is also a factor.

During this process coffee roasting creates unwanted byproducts from beans and natural gas combustion. Adjust the air outlet direction of the chaff collector. The proper weight of each grade of coffee for the blend is charged and the cylinder is rotated. Nordfab duct should not be used as exhaust ducting from the afterburner.

Any exhaust ducting will increase the resistance to air movement and decrease overall air flow a little from the roaster. Clean stream afterburners reduce smoke odor emissions from commercial coffee roaster exhaust. 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 modern styling. 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. Flexible ducting is not recommended for coffee roasting systems. Standard nordfab duct is not designed for unexposed areas where double walled duct is required.

Tighten the three screws to fix the hot air fan and the cyclone chaff collector. The blended coffee then goes to holding bins or to feed hoppers over the roasters. Contact nordfab for assistance with ducting for your coffee roasting application or to learn more about our solution. Connect the main body of the coffee roaster with its green bean loading hopper.

Cyclone to afterburner ducting is included and the whole system will come pre mounted and wired for ease of installation. The exhaust of coffee roasters is typically pushed through vent lines to termination by fans that are pulling that air from the drum and cooling tray. Hoods and ducting can be used to capture the dust and prevent it from settling back into the drum. Any dust or chaff loosened by the mixing is removed by an exhaust system.
