Pass/Fail Checks for a Tubular Pasteurizer Factory Acceptance Test
A buyer's guide to defining practical pass or fail checks for a 1 t/h tubular pasteurizer FAT, covering flow, heat exchange, and documentation questions to put in the RFQ.
For a 1 t/h tubular pasteurizer, the central FAT decision is whether the unit holds rated flow while reaching and holding the required heat-treatment conditions, so define pass or fail around that combined duty rather than around individual components.
Ask the supplier to propose measurable checks: does the unit sustain 1 t/h of liquid through continuous tubular heat exchange without falling below the agreed treatment temperature? What tolerance applies, and how is it recorded? For the fresh juice configuration, confirm how the 5 kW power figure relates to the tested setup, and treat it as a reference value only. Agree whether pass requires stable operation for a defined period, and what happens on a failed hold.
Build the acceptance test around instruments: compare temperature readings against a reference, check flow indication at rated duty, and record alarm and trip responses. Ask what cleaning and inspection access the tubes allow, and whether the demonstration uses water or product-like liquid.
Before requesting a quote, confirm with the supplier which tests they will run, the instruments and tolerances used, the liquid and duration for the demonstration, and what documentation and acceptance criteria will be issued.
