EVAPORATORS
HEATED BY HOT WATER OR BY STEAM

 

The heating is not effectuated by freon, like in heat pump units, but by means of an external jacket crossed by heating water or steam. The vapour condensation is effectuated with air or water condensers.

Simple in their manufacture and maintenance, guarantee a high production because of the good thermal exchange water/steam.

EVAPORATORS
WITH INNER EXCHANGER
AND SCRAPER

 

 

- strong concentration of the process residue

They are utilised for treating big daily quantities with encrusting products.

The scraper supports the thermal exchange and the concentration of the process residue, avoiding in the same time any encrustation on the heating surface

 

 


EVAPORATORS
WITH EXTERNAL EXCHANGERS

 

- for big daily quantities with a limited dimensions plant

- for products with foam formation

They exploit an external energy source.

They are utilised for treating big daily quantities, they are suitable for :

- concentrations till 20% of suspended solids

- concentrations till 1,25 kg/litre of density

For a higher concentration, they can be combined with an auxiliary plant, after the treatment, equipped with inner scraper

MULTIPLE EFFECT
EVAPORATORS

 

- for a great energetic saving, with big quantities to treat

In this kind of plant heating water or steam are utilised for making the liquid to evaporate in the first expansion chamber. The produced steam is exploited, by a heat exchanger, for making the liquid to evaporate in the second evaporation chamber. This procedure, which can be repeated for a third effect, is possible because the vacuum generated in the second expansion chamber is stronger than the vacuum generated in the first one.

They are utilised for treating big daily quantities, they are suitable for :

- concentrations till 20% of suspended solids

- concentrations till 1,25 kg/litre of density

The distilled product goes out sterilised from the process ; particularly suitable for food and pharmaceutical productions.

For a higher concentration, they can be combined with an auxiliary plant, after the treatment, equipped with inner scraper
