Commercial Coffee Roasting Machine 3 Kg Capacity

Q: What roast batch size does the 3 kg capacity support per cycle?

A: Each cycle roasts 3 kg of green coffee beans, which yields approximately 2.4 to 2.7 kg of roasted beans depending on moisture loss during the roast. Operators typically run 3 to 8 cycles per day to meet café service volumes.

Q: How long does a complete roast cycle take from green bean loading to cooling?

A: Roast time ranges from 10 to 15 minutes depending on target darkness level. Light roasts complete in 10 to 12 minutes, while dark roasts require 13 to 15 minutes. Cooling adds an additional 5 minutes before the next batch can be loaded.

Q: Can this machine operate on both 110V and 220V electrical supplies?

A: The KBN1000M-3 operates on 110V, 220V, or 230V supply without modification. Buyers specify voltage requirement at time of order. The 1.24 kW heating element adjusts automatically to the connected supply frequency.

Q: What maintenance schedule applies to the rotating drum and heating element?

A: The drum requires cleaning after every 10 to 15 roast cycles to remove chaff buildup. Heating element inspection occurs every 500 operating hours or quarterly, whichever comes first. TurcoBazaar supplies replacement parts with technical guidance on installation.

Q: Does the unit include temperature monitoring during the roast cycle?

A: The machine includes adjustable heat control but does not feature integrated digital temperature monitoring. Operators adjust roast darkness by controlling heat level and cycle duration. External thermocouples can be added for precision roast profiling.
