Coffee roasting is generally made up of numerous steps that require dust collection.
Coffee roaster exhaust duct.
Nordfab duct should not be used as exhaust ducting from the afterburner.
Any dust or chaff loosened by the mixing is removed by an exhaust system.
The proper weight of each grade of coffee for the blend is charged and the cylinder is rotated.
When the beans are loaded into loaders and drums dust can bloom.
The batch is mixed in a few minutes by helical flanges inside the blender.
Clean modern styling.
Shown is a csa 400 cat catalytic oxidizer.
Clean stream afterburners reduce smoke odor emissions from commercial coffee roaster exhaust.
Connect cyclone chaff collector with its hot air exhaust motor.
Tighten the three screws to fix the hot air fan and the cyclone chaff collector.
Flexible ducting is not recommended for coffee roasting systems.

There are really three stages to the coffee bean roasting process where ducting is needed to exhaust and extract particulate from the air.
Adjust the air outlet direction of the chaff collector.
During this process coffee roasting creates unwanted byproducts from beans and natural gas combustion.
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.
Hoods and ducting can be used to capture the dust and prevent it from settling back into the drum.
Any exhaust ducting will increase the resistance to air movement and decrease overall air flow a little from the roaster.
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.
Hot air motor connection.
Connect the main body of the coffee roaster with its green bean loading hopper.
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.
Coffee roaster ducting coffee roasters are used to develop a chemical change by heating and preparing coffee beans for consumption.
