Circulation type vacuum evaporator 50-300
Vacuum evaporator with a remote circulation type heat exchanger is one of the most efficient evaporation systems. Suitable for boiling heat-sensitive products such as milk, cream, etc.
- No mixing device required, the product has forced circulation!
- Modular system: possibility to choose the vacuum generator, power and heat exchanger type
- Inclined design and bottom valve for 100% product discharge without losses and blind spots
- Insulated upper hatch of the unit for heat retention and safety
- Tangential product inlet into the vacuum vessel for guaranteed evaporation in a thin layer
Vacuum evaporation units are used when it is necessary to evaporate liquids at low temperatures, or at a temperature that is comparatively lower than the boiling point of the product at atmospheric pressure. Most often, this is used to evaporate water from heat-sensitive products. Such units are widely used in the food industry, for example, when condensing milk, cream, and producing condensed milk with sugar.
The vacuum evaporator with circulation is used for concentrating a wide range of liquid products, such as:

Advantages
- Highly efficient and fast evaporation of water from the product due to the circulating function of the vacuum evaporation unit with a heat exchanger in an external circuit.Â
- Possibility of choosing a thermal transfer medium for the heat exchanger (water/steam), as well as the type of heat exchanger (shell and tube / plate).Â
- Due to the powerful condenser and vacuum generator, the system is capable of achieving a deep vacuum, where the boiling point is 59°C. If it is necessary to achieve a boiling point below 59 degrees, it is possible to equip the unit with a special vacuum oil pump, which allows, together with the condenser, to achieve a value of 20 mBar (17°C) - optional.Â
- The bottom valve installed at the lowest hydraulic point of the vacuum reactor, guarantees product processing without blind zones and losses, which is a mandatory requirement for recipes in some industries with precise dosing of components.
- The inclined design of the working vacuum vessel does not require a conical bottom, since the slope allows 100% accumulation of the product directly at the lowest hydraulic point, where the bottom valve is installed!
- The secondary steam removal and condensation system is equipped with a special trap to reduce the likelihood of product carryover into the condenser.
- Included in the basic version, a two-layer upper hatch with an air gap is installed to reduce heat loss and parasitic condensation.
- No mixing device is required; the product pump in the forced circulation circuit constantly mixes the product and intensively heats it in the flow, pumping it through the heat exchanger!Â
- Due to the continuous flow heating of the product, the possibility of local overheating is reduced.
Basic version
The vacuum evaporation unit comprises a single-layer inclined vacuum vessel on a supporting structure, equipped with an external circulation circuit with a product pump and a heat exchanger, a vacuum generation system - an ejector for compressed air, a system for collecting and removing secondary steam. Controls depend on the type and required automation parameters.
Operating principle
Due to the circulation of the product through the heat exchanger, the product is heated in the flow, and upon entering the vacuum tank, the water contained within it almost immediately turns into steam and is removed through the condensate collection and removal system.
As an example, the vacuum evaporator is ideal for concentrating whey, a by-product of milk processing. Operating under vacuum lowers the boiling point of water, allowing moisture to be removed at lower temperatures, which prevents protein denaturation and lactose degradation, preserving the whey’s functional properties and making it suitable for subsequent drying to produce a highly valuable whey powder.
