Forced circulation evaporator systems
Consider forced circulation when final viscosity, particles or deposits make film distribution difficult. Compare pump energy, shear and hold-up against falling film on your measured product duty.
Compare heating arrangements on the same water-removal requirement, product properties and utility conditions.
Evaluate a single heated circulation loop with separate flash separation, vacuum services and concentrate withdrawal for a defined product duty.
↗SystemsCompare staged evaporation with vapour reuse, product-specific circulation duties and coordinated pressure, feed and concentrate controls.
↗SystemsReview mechanical vapour recompression alongside circulation power, product boiling behaviour, electrical service and start-up heating requirements.
↗SystemsAssess thermal vapour recompression against available motive steam, process vapour conditions, heating duty and the intended operating range.
↗Select a connected circuit, then specify the equipment that makes it work. These functional drawings explain the equipment boundary.
Keep the loop moving. The circulation pump sets the flow through the heater. That flow is distinct from the incoming feed and from the mass of water evaporated. Selection must follow the concentrated liquid throughout the planned operating range, including start-up and restart after cooling.

Add heat under pressure. In the common non-boiling heater arrangement, pressure in the circuit limits boiling within the heater. Heat is added before the liquid enters the flash zone. Tube or plate geometry is selected from product behaviour and pressure-drop constraints, rather than the circulation label alone.

Release vapour and retain liquid. The pressure change at the separator enables part of the heated liquid to flash. The vessel provides space for vapour disengagement while maintaining liquid inventory for recirculation. Its level and geometry therefore affect both separation and pump suction.
Review structure & specification →The product name starts the conversation. Measured viscosity, suspended solids, quality limits and cleaning requirements define the equipment.
Define a fruit-concentrate finishing duty from measured rheology, pulp content, temperature history and product-quality requirements.
↗ApplicationsReview vegetable-concentrate duties with attention to particle preparation, viscosity change, pump passages, withdrawal and hygienic cleaning.
↗ApplicationsBuild an extract-concentration requirement around composition, suspended material, sensitive components, fouling observations and final-product criteria.
↗ApplicationsAssess viscous-liquid concentration using temperature-dependent rheology, loop pressure loss, suction conditions and repeated shear exposure.
↗ApplicationsSeparate incoming solids from crystals forming during concentration, then review passage, suspension, abrasion, separation and cleaning requirements.
↗ApplicationsUse deposit location, duty decline and cleaning recovery to review fouling-prone food liquids without assuming circulation eliminates deposits.
↗Bring your feed, target concentrate and available utilities. Define the pump, heater, separator and services together, with an acceptance method for your product.
Prepare your project enquiryPumping, heating and vapour separation have distinct jobs. Review them as a connected circuit.
↗ComparisonUse a common feed, concentrate target and quality boundary before comparing equipment arrangements.
↗EnergySeparate the heat-recovery decision from the hydraulic demand of the liquid circuit.
