FOOD-LIQUID CONCENTRATION / FALLING FILM
Falling film evaporators
for your actual liquid.
Short product hold-up · Controlled vacuum evaporation · Continuous surface wetting
Start with measured viscosity, suspended solids and fouling tendency. Falling film is a candidate for low-viscosity liquids when continuous wetting can be maintained; concentrated, fibrous or crystallizing feeds need a closer review.
Is falling film suitable for your product?
Screen the final concentrate as well as the incoming feed. Measure the product at its operating condition before selecting the evaporator.
| Product condition | Selection question | Next evidence |
|---|---|---|
| Low-viscosity, pumpable liquid | Can the final concentrate maintain a continuous film? | Minimum-load wetting record |
| Suspended particles or fibre | Will the proposed distributor and passages remain open? | Distributor drawing and feed trial |
| Deposits, heat-sensitive solids or foam | Can the run meet product quality and an agreed cleaning interval? | Run and cleaning evidence |
| Crystals or a difficult final viscosity | Does another liquid path fit the duty better? | Compare falling film and circulation alternatives |

Follow the equipment and energy boundary
- Feed distributionUniform liquid entry
- Heated tubesProduct and heating streams separated
- SeparatorConcentrate and vapour outlets
- Vacuum & condensatePressure, cooling and recovery
Functional route, not a fabrication drawing. Inspect all ten modules, including the controls and vacuum/condensation boundary.
Compare the heat strategy on one duty
| Decision | Comparison | Prepare |
|---|---|---|
| Effect arrangement | Single vs multiple effects | Pressure/temperature profile, concentration and minimum load |
| Vapour recompression | MVR vs TVR basis | Steam condition, vapour lift, electricity and start-up heat |
| Scale and evidence | Pilot to industrial scope | Product observations, geometry, utilities and acceptance |

Prepare a comparable project brief
Use the duty calculator to separate feed, concentrate and evaporated water. Keep the assumptions with the result and carry the same basis into the enquiry.
Measured product, clear scope
The equipment shown above is a pilot reference. For an industrial proposal, ask for identified industrial arrangement photographs, module drawings and the agreed supply boundary.
