Falling Film Evaporator Mechanical Vapour Recompression

Descpription Falling Film Evaporators with Mechanical Vapour Recompression for Milk and Milk Products Milk and milk products are high quality foods with defined taste profiles and essential for our daily nutrition. Heat impact negatively influences taste, taste stabilty and the nutrition important components.

dilute process stream (A) is fed into tubes in the falling film evaporator. The concentrated stream (B) is separated from the evaporated vapour (C) which, for a dairy MVR evaporator, is steam under vacuum. The steam from the boiler (D) drives the heat transfer and the steam condensate (Cc) is removed2. In a direct heated evaporator, the vapour ...

In the mechanical vapor recompression, the vapors are compressed by an electrically operated compressor and used again to heat the evaporator.Depending on the application (boiling point increase, heat transfer), one- or two-stage turbo-ventilators or …

Mechanical Vapor Recompression (MVR) evaporator. Mechanical vapor Recompression reduces the energy used in the evaporation process by up to 90% compared with conventional systems. It works by reusing the heat energy contained in the vapor.This energy would otherwise be wasted.In a typical falling film evaporation plant the feed liquid enters ...

Mechanical Vapor Recompression works by re-using the heat energy contained in the vapor that differently would be wasted. In a typical falling film evaporation plant, feed liquid is distributed across many vertical tubes and as it flows down, it forms a thin descending layer. The tubes pass through a jacket of high temperature

Mechanical vapor recompression, in particular, is often employed in industrial evaporators for concentration of solids and uniquely by TKE in certain distillation plants. The objective here is to transfer waste heat from a spent vapor stream by upgrading it to a higher pressure and re-using it to capture its’ useful energy.

Mechanical vapour compression (MVC) or mechanical vapour recompression (MVR) reduces vapour consumption, replaced by a source of electrical energy, resulting in a very low operating cost compared to a multiple effect operation. The vapour produced by the evaporator is sent to a MVC installation, to be compressed and heated up.

Process description. The solution is preheated with condensate in preheaters VW1, VW2 and enters the evaporation circuit. Here it mixes with the circulated solution and is warmed up in heater H. In the evaporator V, solvent (water) evaporates while cooling the solution to the boiling temperature. The resulting vapour steam is washed and ...

The evaporation from the first effect is used as the heating source for the subsequent effect. The vapors produced in the last effect are condensed in a condenser. Steam cost, overall available temperature differential, space requirements and product characteristics are considered to optimize the number of effects. Mechanical Vapor Recompression

The evaporator of RV C series is based on the falling film technology as mechanical vapor recompression system. Wastewater flows down on the internal walls of the heat exchanger tubes, while the vapor produced condensates on the external walls of the same tubes.

The principle behind mechanical vapor recompression (MVR) evaporators is simple. Vapor from an evaporator is compressed (with a fan or compressor) to a higher pressure so that it can be condensed in the evaporator heat exchanger. The compression ratio required is comprised of three components:

The thermal vapor recompression (TVR) 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 use of multiple effects reduces steam consumption in the evaporator. The vapour produced in one effect serves as the heating media in the subsequent effect. Using thermal vapour recompression and/or mechanical vapour recompression in combination with these effects further reduces steam consumption to a fraction of the evaporation capacity. .

For complete wetting it is important that a suitable distribution system is selected for the head of the evaporator. Wetting rates are increased by using longer heating tubes,

Vobis pilot scale vapor compression evaporators (VCE), also called mechanical vapor recompression evaporators (MVR), evaporate lowering the needed energy via an electrical heat pump or compressor principle. Water is evaporated, and then the vapor is recompressed mechanically by an efficient compressor, fan or blower combination, increasing its ...
