The vacuum evaporator, also known as a vacuum concentrator or jam concentrator, is used to remove water or other volatile components from liquid products in order to increase their concentration.
The system can be applied to juice, food products, health-care liquids, oral liquids and selected chemical products. It can also be configured for alcohol recovery and other suitable solvent recovery processes.
Depending on the process requirements, the equipment can operate intermittently or continuously.
Vacuum Evaporator Construction
The concentrator uses stainless steel process components and combines heating, evaporation, vapor separation, condensation, cooling and liquid collection in one integrated system.
Concentration Tank
The concentration tank uses a jacketed structure for indirect heating. Steam can be introduced into the jacket according to the required processing temperature.
Condenser
The condenser processes generated vapor and supports separation and recovery of condensable components during vacuum evaporation.
Gas-Liquid Separator
The gas-liquid separation section helps separate entrained liquid and vapor during the concentration process.
Cooler
The cooling section can reduce the temperature of recovered condensate or process liquid according to the system configuration.
Liquid Receiving Barrel
The receiving section collects the final liquid or recovered condensate after the corresponding process stage.
SUS304 / SUS316L
Stainless steel 304 or 316L can be selected according to product characteristics, hygiene requirements and project conditions.
How Does a Vacuum Evaporator Work?
Vacuum evaporation lowers the boiling point of the liquid, allowing concentration to take place under reduced pressure.
Product Feeding
The liquid product enters the concentration vessel.
Steam Heating
Steam heats the product indirectly through the jacket.
Vacuum Evaporation
Reduced pressure lowers the boiling point and promotes evaporation.
Vapor Separation
Vapor and liquid are separated through the system components.
Condensation & Recovery
Vapor is condensed and recovered according to the process design.
Vacuum Evaporator Applications
The equipment can be configured for a variety of liquid concentration and recovery processes.
Fruit Juice
Concentration of fruit juice and other liquid fruit products.
