CONTINUOUS VACUUM COOLING and DRYING UNIT

In this unit the soap is cooled and solidified. At the same time the water content in the finished product is reduced.

This process takes place in a "flash" type expansion vacuum chamber.
Under these conditions, the partial pressure of water is much higher than the one it had at that vacuum degree, therefore it quickly evaporates resulting in cooling and concentration of the soap.

The soap is pre-heated under pressure and than allowed to expand through a nozzle which sprays it as a film on the expansion chamber walls from where it is removed by scrapers.
