Consider when
Review particle passage, heat duty, pressure relationship and product-specific validated holding conditions.
Check the limit
Narrow passages may not suit fibrous puree or larger particles; heat-exchanger choice alone does not validate the process.
Factory interface
Allow plate opening and gasket service; coordinate leak detection, CIP and sterile downstream transfer where required.
Consider when
Review flow range, passage geometry, pressure drop, fouling and validated thermal requirements.
Check the limit
Product changes can invalidate an earlier holding or heat-transfer basis; published generic schedules are insufficient.
Factory interface
Coordinate tube inspection, instrument calibration, divert logic, cleaning and any defined sterile boundary.
Consider when
Use rheology at processing temperature, maximum particle size and hydraulic review to select the geometry.
Check the limit
Wider passages do not establish particle heating or holding performance; these require product-specific validation.
Factory interface
Check pump and valve access, retained product, cleaning return conditions and holding-section inspection.
Consider when
Review container mass, loading density, heat penetration, closure integrity and zone balance.
Check the limit
Liquid flow rate cannot size the tunnel; package behaviour and validated container treatment govern the duty.
Factory interface
Review spray-zone access, conveyor service, water management, drainage and start/stop handling of packs.
Consider when
Define product heat penetration, package resistance, load pattern and process-authority requirements.
Check the limit
A generic time-temperature recipe is unsuitable; each product, pack and loading arrangement needs validation.
Factory interface
Plan basket handling, vessel inspection, interlocks, calibrated process recording and qualified maintenance.
