Trialing a Tubular Pasteurizer With Your Own Liquid
A buyer's guide to planning a tubular pasteurizer demonstration using the buyer's actual liquid, with practical questions for the trial protocol and acceptance test.
Before signing off on a tubular pasteurizer, ask the supplier to run your own liquid through the unit rather than a generic test fluid. Because the equipment is built for continuous tubular heat exchange of liquids, the demonstration should use material that matches your product's handling behavior, not water alone.
Build the trial around the rated flow of 1 t/h and confirm whether the supplier proposes to demonstrate at that rate, below it, or across a range. Ask how the 5 kW fresh juice configuration relates to the liquid you will supply, and whether the trial unit matches the proposed configuration. Agree in advance on what will be measured, how samples will be taken, and what counts as a pass.
Useful questions for the request for quotation or demonstration: What liquid volume is needed? How will the supplier clean and change over between products? What records will be provided from the run? If your material is viscous, pulpy, or temperature-sensitive, ask whether the trial can reflect that.
Before requesting a quote, confirm with the supplier which liquid will be used in the demonstration, the flow rate and power configuration of the trial unit, the sampling and acceptance criteria, and what documentation from the run will be supplied.
