The first sample from clean equipment cannot establish an entire production run. A viscous-product heat-treatment proposal must describe the product envelope, the run conditions and how deposit formation is assessed.
Choose the passage with evidence
Review candidate heat-exchanger principles against the sample and its formulation. Ask for the reasons behind passage geometry, surface renewal where proposed and the selected flow range. Published examples explain possible arrangements; they do not qualify the offered machine.
Measure a representative run
Record product flow, relevant temperatures, pressure and any loss of performance. Include the planned operating duration and a defined interruption. A short water test is an installation check, not a banana-product performance trial.
Join treatment to recovery and cleaning
Identify where off-specification product is diverted and how retained product is handled after a stop. Agree the cleaning endpoint and inspection approach with the responsible team. Exact safe process conditions belong to the validated product/process specification.
Source context
FAO: Fruit-specific preservation, banana puree. Historical description of pulping, air removal, heat exchange and preservation routes. Exact machine selection needs current product trials.
The equipment-check questions above are a project-preparation framework, not a validated operating procedure.
