How should liquid seasoning dosing be evaluated when buying an automatic cooking machine?

Evaluate liquid seasoning dosing by first checking whether the pump or flowmeter handles your thickest sauce in-house, then verify single-shot deviation as viscosity shifts and whether line hold-up is counted in the recipe. During the trial, run ten consecutive batches each of cooking oil, dark soy and water, weigh them and calculate the range; repeatability beyond plus or minus five percent means adjusting pump speed or shortening tubing. Timed valve opening will drift badly with thick sauces, so specify pulse dosing or a progressive-cavity pump. Put the tolerance, cleaning interval and calibration method into the technical agreement before signing off on the wok.
