Professional Coffee Grinder | TurcoBazaar W819A

Q: What bean capacity does the 400g hopper provide during service?

A: A 400g hopper holds approximately 40-50 double espresso doses depending on grind setting and bean density. Darker roasts occupy more volume per gram than light roasts. Operators typically refill 2-3 times during a busy breakfast service.

Q: How does the 60-step grind selector affect extraction?

A: Each increment changes particle size distribution by approximately 50-80 microns. Finer settings increase extraction time and pressure for espresso preparation. Coarser settings reduce contact time for drip and French press applications.

Q: Which portafilter basket sizes fit the grinder cradles?

A: The unit includes two cradles: one for 50-54mm baskets common in domestic and light commercial machines, and one for 58mm baskets standard on commercial espresso systems. Both cradles hold portafilters hands-free during dosing.

Q: How does conical burr design differ from blade grinding?

A: Conical burrs shear beans between two precision surfaces at lower rotational speed than blade cutters. Reduced friction generates less heat, preserving volatile aromatic compounds. Particle size distribution remains more uniform across dose weight.

Q: What maintenance schedule applies to commercial burr grinders?

A: Inspect burrs every 200kg throughput for wear patterns or chipping. Clean daily with brush to remove fines and oils that affect grind consistency. Replace burr set when grind time increases by 20% at identical settings or when particle distribution shows excessive fines.
