Model: NL-KFSMT-10
The problem
Endurance aging is the most gruelling stage of a coffee machine line: the four modes - preheat, brewing, steaming and keep-warm - must cycle for hundreds of hours, knobs must be turned by hand and the extraction head released by hand; one missed mode change on the night shift and the whole run starts over. Ten machines tested together simply cannot be watched by people, and no traceable record is left.
Capability
The bench hands the aging program to the controller. Intelligent water filling stops automatically at the set volume; five pneumatic fingers per station turn the knob through the set number of cycles and durations to switch modes; preheat, brewing, steaming and keep-warm proceed as a four-mode program cycle; extraction pressure is monitored across 0-3MPa at 0.01MPa accuracy with the extraction head relieved automatically after each cycle. Power, current, voltage, outlet temperature, outlet volume, steam-pipe water content and extraction pressure are sampled cycle by cycle; the screen shows each machine state, elapsed time and completed cycles, an RJ-45 port writes the data into MES, and any fault protects that station and lights the lamp while the other nine carry on. A 100-240V variable supply rated 30kW suits export models; cable rating above 60A, master leakage switch plus an independent leakage switch per station, splash-proof fire-retardant bench with drainage.
Applicable standards
The assessment follows the heating, leakage current and structural safety clauses of GB 4706.1 General requirements for household and similar electrical appliances, with whole-machine safety under GB/T 4706.19-2024 for liquid heating appliances; aging modes, cycle counts and judgement thresholds follow the customer technical agreement and the machine specification.
