SOAP DRYING AND COOLING
After the Saponification, the obtained soap is hot and in liquid form; at this point of the process the soap is solidified and transformed in soap noodles, soap flakes or directly in extruded soap bars. Cold process soap is left in the molds for 1 day and it solidifies naturally and the day after is removed from the molds. In industrial process it is necessary to use a continuous solidification system, due to the high capacities of the industrials saponification plants. In soap industry 2 systems are used: the vacuum spray dryer (also called Soap Vacuum Dryer) and the Chill Rolls.
