Turn the question into a controlled engineering duty
Characterize coffee oils, color, fines, protein and heat deposits and set circuit, chemistry, hydraulics and verification. The acceptance basis must resolve worst-case formula and run phase together with circuit and surface materials, then assign operating limits, responsible roles and controlled records for this exact task. Control coffee material and extract specification, recipe and allergen status, physical and thermal stability, oxygen sensitivity, preservation authority, package barrier, sensory reference and intended storage. Record roast age, grind and extraction convention, useful-yield definition, filtration and hold limits, protein and emulsion risk, worst-case thermal residence, aseptic or retort boundary and standardized sensory serving so extraction and preservation changes remain traceable. Record every input with units, source, approval status, credible range and decision owner. Keep an unknown visible when it can change sizing, hygiene, packaging, automation, utilities, cost or schedule.
