Multi-effect falling film evaporators with thermal vapour recompression (TVR)

Multi-effect falling film evaporators with a thermal vapour recompression are good valued and extremely energy efficient. The thermo-compressor uses the high pressure steam and mixes the low pressure vapours with it. A thermo compressor substitutes one or two evaporator column compared to a multi-effect evaporator, i.e. the specific steam consumption of a TVR-evaporator is reduced by around 20 to 50 %.

 

APPLICATION

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.

 

HIGHLIGHTS

Long production runs due to high hygienic standards

Proven technology

Fully cleanable (Cleaning in Place)

 

WORKING PRINCIPLE

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.

FAQ

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.
