soap drying plant

Drying plant diagram - Soap factory

The soap drying plant is used for drying of laundry soap and for the base of the toilet soap. The process has four steps:

LIQUID SOAP FILTRATION

The liquid soap from the saponification step is pumped by the Filtration Pump through the soap filter to the feed tank.

The saponification step can be made using three different process: by boiler, by continous saponification plant or by Soap Crutchers.

The Soap Filter guarantees that the liquid soap wich come from saponification process comes out without any kind of impurities and other things which could contaminate the soap. We also protect the rest of the machines after this step.

The Soap Feed Tank is used to accumulate filtered liquid soap before it is pumped into the heating step.

LIQUID SOAP HEATING

After the soap feed tank, the liquid soap is fed by the Feed Pump into the Heat Exchanger where it is heated. In this way the water evaporates and the soap starts to dry before to vacuum spray Chamber.

DRYING

The liquid soap is splashed into the Vacuum Spray Chamber through the feed pump. The controlled combination of temperature and vacuum allows the water to evaporate obtaining the desired degree of humidity in the soap. The steam separated from the soap is sucked in and condensed in the barometric group.

The soap is scraped from the internal walls of the vacuum spray chamber by means of spatulas precipitates until it falls into the Plodder.

To recover and recycle the soap particles produced in the vacuum spray chamber we use cyclones. Cyclones allow to separate the soap particles from the vapours produced inside the vacuum spray chamber.

STEAM CONDENSATION

All the steam produced in the drying plant are sucked from the inside of the vacuum spray chamber and cyclone by the vacuum group and are condensed in the Barometric Condenser. The condenser continuously transforms the steam produced during the soap drying process into water.

There are different possibilities of drying plant configuration, depending on the level of production (Kg/h) and type of soap (laundry or toilet soap bars).
