Why Do You Need to Clean Your Roasting Machine?

There are several technical aspects of why you need to clean the coffee roaster machine. The frequency of using a coffee roaster will affect the performance of the machine. One example of which parts of a coffee roaster machine should be cleaned is the drum roasters.

It's a drum that has a section called the cyclone with the function to trap all the coffee residue in it. The residue will travel in hot air out of the exhaust pipe, and the cyclone will prevent particles from coming out through the exhaust pipe. After intensive use, you must remove the cyclone and disassemble it. Clean it until there is no residue.

Sometimes the membrane of the coffee fruit will remain after you process the bean. Although the membrane will come off during the roasting process, you need to clean the parts that are still attached to the residue and can hamper the engine's performance when used too often.

The process of roasting coffee beans will deposit coffee oils, creosote, and solid waste products. If this waste continues to build up inside the machine, it will create friction and the airflow will be disrupted so that the engine is quickly exposed to overheating.
