DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soap manufacturing apparatus, and more particularly to a soap manufacturing apparatus which uses waste cooking oil produced at home as a raw material, and is capable of manufacturing soap from a small amount of waste cooking oil. The challenge is to provide soap manufacturing equipment.

[0002]

2. Description of the Related Art The treatment of waste cooking oil generated in the home kitchen has become a serious problem. When waste cooking oil is discharged into sewage, a large amount of water is required for processing, and when it is included in paper or cloth and discarded as combustible waste, a large amount of heat is generated and damage to the incinerator, etc. Problem occurs. In recent years, the problems of synthetic detergents on the human body and water pollution have become problems, and the use of soaps, which decompose faster than synthetic detergents and have no adverse effect on the human body, has been reviewed. Soap can be obtained by reacting various fats and oils, which are glycerin esters of fatty acids, with an alkali such as sodium hydroxide to carry out a saponification reaction, but similarly obtain soap by using decolorized waste edible oil as a raw material. Therefore, it is recommended to use the waste edible oil as a raw material of soap from the viewpoint of solving the problem of processing the waste edible oil and effectively using the waste edible oil.

Waste edible oil, which is produced in large quantities for commercial use, has been conventionally collected and processed, but the amount of waste edible oil produced in the kitchen of each individual household is small, which is necessary for the production of soap. It is not easy to recover a large amount of waste cooking oil from households. When producing soap using waste edible oil as a raw material, it is difficult to obtain high quality soap if the amount of waste edible oil is small. It was necessary to recover.

The production of soap is mostly due to the many years of experience of a specialist called "Kamashi", but the present inventors produce soap from a small amount of waste edible oil for these specialists. After consulting about the method, the experts thought that even a small amount of soap could not produce high-quality soap, and that it was impossible to develop a small-sized soap manufacturing device. As a result of intensive studies, the present inventors have already provided a soap manufacturing apparatus using about 20 liters of waste cooking oil as a raw material. FIG. 4 shows an example of a 20-liter soap manufacturing apparatus. A heating device 4 in which waste edible oil 45 is put in a reaction vessel 41 and gas is used as a fuel from the lower part of the reaction vessel 4
4 to maintain the temperature inside the reaction container at a predetermined temperature by heating with a driving device 43 connected with a stirring device 42.
While rotating the agitated waste cooking oil in the reaction vessel,
A saponification reaction is performed by adding a predetermined amount of sodium hydroxide aqueous solution into the reaction vessel, and after the reaction is completed, the soap is taken out from the reaction vessel.

Securing a quantity of 20 liters of domestic waste cooking oil is not easy. If a small amount of waste edible oil such as several liters is used as a raw material in such an apparatus, it is difficult to produce high-quality soap, and the resulting soap has a problem that oil content remains. Further, when soap is produced from waste edible oil, the volume increases about three times, so a reactor for treating 20 liters of waste edible oil requires a reaction vessel of about 80 to 100 liters. Therefore, a small soap manufacturing apparatus has been demanded.
