How should eight-hour continuous operation be evaluated when buying an automatic cooking machine?

An eight-hour run is only meaningful when the wok cooks real recipes, not when it idles. Watch the pan's temperature climb, whether overheat or motor alarms trip mid-shift, and how the tossing drive and tipping mechanism behave as the load drifts. Output rhythm and portion weight must stay steady from the first batch to the last. Replicate lunch and dinner order density, log the gap between first and final dishes, and sample cooked product from the middle of the shift. Photograph pan residue and the stirring shaft, since these reveal wear that later drives seasoning checks and maintenance intervals.
