04 / Acceptance and handover
Prove the result under a representative production condition
Hold representative concentrated syrup at thermal boundaries, inspect surfaces and filters, and verify no crystal growth, minimum temperature, alarm, recovery and affected-route cleaning. Reconcile sweetener and water mass, trend concentration and temperature, challenge recipes and transitions, and verify released syrup, losses, residues and cycle performance. Put the sample or test material, method, instrument, production state, duration, limit, witnesses, retained record and deviation authority in the protocol before testing begins. Requalify when a product, package, site, speed or connected system invalidates the accepted basis.
