Choose the heat-transfer arrangement for the juice condition
A falling-film arrangement distributes liquid over heating surfaces for evaporation under the selected pressure. Film distribution and operating flow matter as the solids content changes.
A forced-circulation arrangement moves product through a heater before the evaporation and separation stage. It may be considered when viscosity, solids or deposit behaviour call for that circulation duty. The product range, rather than the exterior shape of a vessel, determines the appropriate selection.
Start with the required ingredient, then establish water removal
Feed mass flow and the concentration change establish an initial material balance. Record the concentrate and water-removal duties separately, then account for additional streams or losses appropriate to the selected process.
A volumetric juice rate needs the density at its stated temperature and concentration before use in a mass balance. A whole-fruit intake rate is further upstream and cannot stand in for the evaporator feed. The required outlet concentration is an ingredient specification, not one fixed value for all pomegranate products.
Include circulation and utilities in the package
| Configuration choice | Associated equipment duty |
|---|---|
| Single, double or multiple effects | Heating and vapor reuse across the selected stages |
| Steam or selected thermal supply | Heat delivery at the required operating conditions |
| Vacuum and condenser | Vapor handling, gas removal and available cooling |
| Liquid circulation and discharge | Flow and pressure for the changing concentrate condition |
| SUS304 or SUS316L contact materials | Compatibility with the product and cleaning procedure |
| PLC and CIP connections | Coordinated operating states and cleaning circuits |
Assess the product through the concentration run
Temperature exposure, residence and vapor handling affect the resulting ingredient. Compare colour, aroma and the agreed composition under representative operating conditions rather than treating vacuum alone as proof of quality retention.
Allow access to circulation pumps, valves and heat-transfer sections for service. Cleaning must cover the actual deposit locations and flow paths. The concentrate outlet then connects to the selected treatment and packaging route; evaporation alone does not establish shelf life.

Does adding more effects guarantee a specific steam saving?
Utility demand depends on the concentration duty, feed temperature, operating range and the selected heat-recovery arrangement. Compare energy figures only on the same stated product and utility basis.
