Coffee Roaster Exhaust Duct

Hot air motor connection.

Coffee roaster exhaust duct.

The proper weight of each grade of coffee for the blend is charged and the cylinder is rotated. Any dust or chaff loosened by the mixing is removed by an exhaust system. 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. Any exhaust ducting will increase the resistance to air movement and decrease overall air flow a little from the roaster.

Tighten the three screws to fix the hot air fan and the cyclone chaff collector. Hoods and ducting can be used to capture the dust and prevent it from settling back into the drum. Connect cyclone chaff collector with its hot air exhaust motor. 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. Standard nordfab duct is not designed for unexposed areas where double walled duct is required. 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.

When the beans are loaded into loaders and drums dust can bloom. Flexible ducting is not recommended for coffee roasting systems. Adjust the air outlet direction of the chaff collector. The batch is mixed in a few minutes by helical flanges inside the blender.

The initial roasting stage. Any bends will also restrict airflow and the total distance of exhaust pipe is also a factor. Clean modern styling. Shown is a csa 400 cat catalytic oxidizer.

Nordfab duct should not be used as exhaust ducting from the afterburner. The blended coffee then goes to holding bins or to feed hoppers over the roasters. 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. Clean stream afterburners reduce smoke odor emissions from commercial coffee roaster exhaust.

Coffee roaster ducting coffee roasters are used to develop a chemical change by heating and preparing coffee beans for consumption.
