Turn the question into a controlled engineering duty
Prove extraction, blend, thermal route, package, good output, holds, changeover, cleaning and quality as one production system. The acceptance basis must resolve reference tea lots and recipes together with normal and disturbed line states, then assign operating limits, responsible roles and controlled records for this exact task. Define tea grade and lot variability, extraction and sensory targets, formula, solids and acidity, oxygen and light sensitivity, preservation route, package, production campaign and shelf-life methods. Name the extraction yield convention, actual time-temperature reference, fines and clarity boundary, maximum extract and treated-product hold, approved sensory preparation, color method and light-exposure case so raw-material and process drift can be distinguished. 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.
