How to Clean & Maintain Your Coffee Roaster

Maintaining your coffee roaster is essential for ensuring consistent flavor, extending the life of your machine, and enhancing your overall roasting experience! To make sure your equipment works as it should, Mike Romagnino breaks down best practices for roaster maintenance, safety, and how to prevent potential issues down the line.

Coffee Roaster Maintenance Schedule

A clean coffee roaster ensures that your machine runs efficiently and helps you avoid potential hazards like roaster fires. Following a preventative maintenance schedule will help you stay organized with your roaster cleaning & upkeep. Furthermore, you should document your cleaning and maintenance routines to track performance and identify issues early.

Daily Maintenance

• Remove Chaff: Chaff collects during roasting. While it can affect flavor, chaff can also cause a fire. Remove it from the collection bin both while you roast and at the end of the day.

• Wipe Surfaces: Use a damp cloth to wipe down the exterior and any accessible interior surfaces.

• Clean Cooling Tray Surface: Wipe down the surface of the cooling tray between batches and when you’re finished roasting for the day.

• Vacuum Cooling Traying: Take the time to vacuum out the debris from underneath the cooling tray.

Weekly Maintenance

• Examine Machine Components: Check the condition of the drum, fan, and heating elements for any signs of wear or damage.

• Inspect Airflow: Make sure there are no obstructions.

• Check Filters: Clean or replace air filters as needed to ensure optimal airflow.

• Scan Belts: Look for rips, fraying, and general wear and tear.

• Clean Hopper: Clean and wipe down your roaster’s green coffee loader.

Monthly Maintenance

• Lubricate Moving Parts: Grease up the gears and bearings so they move smoothly.

• Clear Sensors: Wipe down the sensors until they’re clean and fully functional.

• Inspect Electrical Components: Check all machine wiring and components for any signs of wear or fraying.

Quarterly Maintenance
