Roaster Vacuum
A heat-resistant vacuum for clearing chaff, dust and debris from the machine and its surrounds.
Overview
Loose chaff and coffee dust settle everywhere around a roaster: in the tray, under the drum, along the cooling tray rim and across the floor. A vacuum with heat-resistant components and a fine filter clears it quickly and keeps fine dust out of the air.
Using it well
- Let the roaster cool completely before vacuuming. Warm embers in a dust bag can smoulder for hours.
- Empty the canister outside and into a metal container.
- Vacuum the floor around the machine too. Fine coffee dust is both slippery and combustible.
Never vacuum hot embers. Let the machine cool fully first, and use a vacuum with a heat-resistant, fire-safe collection chamber. Empty after every use - a vacuum full of combustible dust is a fire risk, especially if stored near the roaster.
Why this matters
The roaster vacuum sits in the cupping & cleaning stage of a roast. Getting it right removes one source of variation, which matters because roasting rewards consistency more than any single clever adjustment. Change one variable at a time, record what you did, and compare batches rather than judging any single roast in isolation.
If you are building a complete setup, start with the instruments that measure what is happening - a probe, a scale and a logger - before buying anything that promises a better result by itself. Measurement first, equipment second.
