Mass balance
Provide feed Brix, target Brix and hourly feed so evaporation load and condensate volume can be calculated.
Evaporation & Concentration
Forced Circulation Evaporator
A forced circulation evaporator is considered when viscosity, solids or fouling risk makes falling film evaporation less suitable.
Equipment role
What this equipment does.
Forced circulation evaporator for viscous or fouling-prone fruit products.
For Forced Circulation Evaporator RFQ, provide feed and target concentration, capacity, viscosity and fouling and quality target. These data are used to confirm the configuration, interfaces and quotation scope.
Typical applications
Where it is used.
- Viscous puree concentration
- Sauce or paste concentration
- Fouling-prone materials
- High-solids products
Process position
Typical position in the processing line.
The position may vary according to finished product route, plant layout and sanitary design.
Product or material feeding
Control feed rate, inlet height and raw material condition before Forced Circulation Evaporator so the machine receives a stable load without bridging or unnecessary product damage.
Main processing operation
Review this step with product data, line layout and sanitary requirements so Forced Circulation Evaporator can be integrated without creating a bottleneck.
Transfer or holding
Confirm outlet height, pump or conveyor interface, buffer need and next-machine inlet so the section connects cleanly to the production line.
Cleaning and inspection
Provide access for inspection, drain-down and cleaning so product-contact parts can be maintained without excessive downtime.
Connection to next module

Engineering notes
Engineering Notes for Forced Circulation Evaporator Selection
Forced Circulation Evaporator is commonly discussed for viscous puree concentration, sauce or paste concentration, fouling-prone materials, high-solids products. The goal is to make this module work as part of a complete fruit and vegetable processing line, not as an isolated catalogue item.
Evaporation, deaeration and holding equipment affects Brix, aroma retention, foaming, oxidation and line stability. Falling film evaporation is normally discussed for lower-viscosity juice streams, while forced circulation may be considered for thicker or more fouling-prone products. Vacuum deaeration helps reduce entrained air before sterilization or filling, and buffer tanks stabilize flow between batch and continuous sections.
The important RFQ data are feed Brix, target Brix, viscosity, pulp or fiber content, foam tendency, heat sensitivity, cleaning interval and available steam or cooling water. Low-temperature vacuum concentration can protect quality, but the final design depends on real product behavior. For viscous puree or paste, fouling and pumping limits are often more important than nominal capacity. The RFQ checklist below should be used to confirm the sizing data before quotation.
- Confirm whether the product is clear juice, cloudy juice, puree, paste or concentrate.
- Define target Brix and allowable aroma or color change before choosing concentration technology.
- Check foam and air removal needs when filling accuracy or oxidation is a concern.
- Use capacity and Brix values as preliminary references until mass balance is reviewed.

Equipment RFQ Checklist
Use this checklist when requesting a quote for Forced Circulation Evaporator. If values are preliminary, mark them as reference only so the engineering team can show adjustable options.
| RFQ Field | What to Provide | Why It Matters |
|---|---|---|
| Feed and target concentration | Product name, feed Brix, target Brix and whether values are measured or preliminary. | Feed Brix and target Brix define the water removal and mass balance. |
| Capacity | Feed flow per hour, operating hours, seasonal schedule and expected product output. | Flow and concentration ratio determine heat-transfer area and circulation duty. |
| Viscosity and fouling | Viscosity at relevant Brix and temperature, pulp, fiber, pectin, foam tendency and acceptable cleaning interval. | Fouling and viscosity determine evaporator type, pump selection and run length. |
| Quality target | Maximum product temperature, aroma recovery expectation, color sensitivity and heat exposure limit. | Quality limits affect vacuum level, effect arrangement and residence time. |
| Utilities and CIP | Steam pressure, cooling-water temperature, vacuum system preference, power, condensate handling, CIP recipe and drainage. | Steam, vacuum, cooling and cleaning conditions govern practical performance. |
Buyer questions
Equipment FAQ
When is falling-film evaporation suitable?
Falling-film evaporation is commonly considered for lower-viscosity, pumpable juice streams where short residence time is useful. Product distribution and minimum wetting must still be checked across the expected operating range.
When is forced circulation considered?
Forced circulation may be considered when viscosity, solids or fouling make stable film flow difficult. Pumping energy and residence time must be balanced against run length and cleaning frequency.
Why are feed Brix and target Brix both required?
Both values are needed to calculate water removal, concentrate output and utility load. A target Brix alone does not show how much evaporation duty the equipment must provide.
Can Forced Circulation Evaporator be customized?
Yes. Capacity, product-contact or container-contact parts, motor and drive selection, controls, guarding, inlet and outlet arrangement, platform and line interfaces can be configured from the project data listed on this page. Final scope is confirmed before manufacturing.
Why is there no fixed online price for Forced Circulation Evaporator?
The same equipment name can cover different capacity, construction, controls, guarding, accessories and upstream or downstream interfaces. A fixed public price would hide those differences. The RFQ process confirms the required scope before a project quotation is prepared.
