Abstract

The possibility of using waste edible oil as a secondary raw material in the production of sanitary and hygienic detergents is described. A model of the drying mechanism of the hygienic soap base and the results of the study of temperature conditions are presented. Model constructions of the drying mechanism of the sodium soap base and the temperature mode of the drying process are considered based on the physicochemical structure and phase composition of the soap composition. A diagram of a complex cooking and drying unit is presented using the example of producing toilet soap from waste edible oil. A diagram of the mechanism for removing moisture as a result of drying the soap base with a lamellar structure is presented. The results of the study of the temperature mode of the complex cooking and drying unit showed that with a decrease in humidity, the temperature should be minimal and, accordingly, the residual vapor pressure will also be lower. Equations of material and heat balance for the process of producing toilet soap from waste culinary oil are presented. The results of the proposed studies are planned to be used in the production of sanitary and hygienic soap for the service sector, using waste culinary oil as a secondary raw material.
