Title: METHOD AND UNIT OF DRYING BASIC SOAP
Abstract:
An apparatus or unit (1) for drying basic soap, and a relative method, which involves carrying out at least one soap cooling step by conductive heat exchange. Cooling is achieved by conductive heat exchange between the soap spread by a dedicated system and the cooling means circulating in the jacket applied outside the chamber wall. Preferably, the wall is cooled by fluid circulating in a jacket formed on the body of the new cooling chamber. A precooling step is also contemplated by using a vacuum degree lower than those currently used in this type of production, with which the soap is only partially cooled. The special system for introducing the soap into the apparatus eliminates or dramatically reduces the creation of soap dust, resulting in reduced operational and ecological problems, thus simplifying the vacuum system of the plant.
