Low Noise Level Custom TVR plate evaporator in Food & Beverage Industry


Thermal vapor recompression (TVR)

Use valuable energy intelligently & multiply

The thermal vapor recompression builds on the same principle as the mechanical alternative, but uses only a portion of the resulting vapor for heating the system. The compression of the steam for heat recovery takes place in a steam jet pump. This is usually designed for a specific operating point and works on the jet pump principle. The resulting energy savings correspond in many cases in about an additional evaporator stage.



The Evaporator Falling Film TVR provides a fully automatic and continuous evaporation system. The Evaporator Falling Film TVR is suitable for the production of the complete range of products. The system is customer specific designed, and therefore available for a wide range of product compositions and capacities.



Long production runs due to high hygienic standards

Proven technology

Fully cleanable (Cleaning in Place)



The Evaporator Falling Film TVR is fed from the wet process area. From the balance tank product is heated to at least boiling temperature of the first calandria, depending on the final product demands. This can be done by plate heat exchangers, tubular heat exchanger and/or direct heaters by use of condensate, excess vapours, steam and/or hot water. After the heating process the product is fed to the first calandria where the product starts to evaporate. The evaporator works according the falling film principle, which means that product and vapour are flowing downwards through the tubes. At the bottom, concentrate falls down and vapour is sucked into the separator, whereby the smaller concentrate droplets are separated from the vapour. Concentrated product is pumped to the next pass, whereby the product is further concetrated. After the final calandria pass product is pumped, depending on the product and required concetrate properties, to a next calandria, concentrate tanks of the dryer or via a flash cooler to crystallisation tanks. As the amount of water evaporation is limited and the required temperature difference is relatively high, steam is used as driving force. This is referred to as thermal vapour recompression (TVR). Depending on capacity and specific product needs the number of stages and thermo-compressors are defined. A density controller in the concentrate flow is used to set the steam flow to the thermo-compressor.


How Thermal Vapor Recompression Evaporators Work

To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor. A thermocompressor is similar to a steam-jet air ejector used to maintain vacuum in an evaporator.

Only a portion of the vapor from an evaporator can be compressed in a thermocompressor with the remainder condensed in the next-effect heat exchanger or a condenser. A thermocompressor is normally used on a single-effect evaporator or on the first effect of a double- or triple-effect evaporator to reduce energy consumption. Like mechanical recompression, thermal recompression is more applicable to low boiling-point rise liquids and low to moderate differential temperatures in the heat exchanger to minimize the compression ratio.

The double-effect evaporator with thermal recompression requires 33% less steam than the conventional double effect. In essence, the steam usage for the double effect with thermal recompression is comparable to that of a triple-effect evaporator.

What is the difference between an MVR and TVR evaporator?

MVR is a Mechanical Vapor Recompression system, energy source is Power/Electricity, very low energy consumption

TVR is a Thermal Vapor Recompression system- energy source is steam, energy consumption dependent on number of stages (calandrias) of evaporation.


Why use a Falling Film evaporator?

The falling film evaporator is a gentle way to remove water in a very energy efficient way. Small footprint for high evaporation.


How high can you go in total solids?

This is very dependent on type of product, all products must be individually considered, mostly the stickiness and viscosity will determine the total solids.


Does viscosity have an impact on the possibility to use an evaporator?

Yes, the viscosity is a very critical factor for a good evaporation, the product must be pumpable.


What kind of products can you run on a falling film evaporator?

Almost all pumpable liquids and soluble products can be run on a falling film evaporator.
