Coffee Roaster Exhaust Duct

Connect the main body of the coffee roaster with its green bean loading hopper.

Coffee roaster exhaust duct.

Hoods and ducting can be used to capture the dust and prevent it from settling back into the drum. Clean modern styling. The diameter of the pipe is important but depends on a few factors. During this process coffee roasting creates unwanted byproducts from beans and natural gas combustion.

Cyclone to afterburner ducting is included and the whole system will come pre mounted and wired for ease of installation. Hot air motor connection. Tighten the three screws to fix the hot air fan and the cyclone chaff collector. Connect cyclone chaff collector with its hot air exhaust motor.

The blended coffee then goes to holding bins or to feed hoppers over the roasters. Coffee roaster ducting coffee roasters are used to develop a chemical change by heating and preparing coffee beans for consumption. Standard nordfab duct is not designed for unexposed areas where double walled duct is required. Adjust the air outlet direction of the chaff collector.
