Different hydraulic duty
Viscous product changes the gas-release path
A distributor that works for a low-viscosity beverage may not create the same film, residence or foam margin in puree or sauce.
Design factors
Four questions before vessel sizing
Each question affects product presentation, controllability, cleaning and the safe operating envelope.
Can the product spread?
Viscosity, yield stress, temperature and particles determine whether a thin layer is practical.
How far will foam expand?
Headspace, level control and operating ramp must reflect the product's vacuum response.
Can it leave under vacuum?
Outlet pump type, suction condition and downstream back-pressure are part of the duty.
Can every surface be cleaned?
Distribution devices, vessel internals, seals and low points belong in the CIP review.
Evidence path
Bench observation before performance promise
For an unfamiliar or shear-sensitive product, testing is more valuable than borrowing a viscosity limit from another machine.
- 1
Characterize
Product temperature curve, viscosity method, solids, particle distribution and foam tendency.
- 2
Observe
Distribution, bubble release, foaming, aroma carry-over and discharge behaviour.
- 3
Measure
Agree inlet and outlet sampling, dissolved-oxygen method and quality observations.
- 4
Specify
Convert the approved test boundary into equipment, controls, cleaning and acceptance scope.
RFQ preparation
Send the data that generic catalogues omit
Rheology
Viscosity value, temperature and test method.
Solids
Pulp, particle size and deformability.
Foam
Observed expansion and antifoam limits.
Cleaning
Recipe, time, temperature and drainability needs.
