Problems solved by technology

[0004] At present, the use of waste oil to make soap is usually made by industrial heat. During the manufacturing process, the nutrients in the oil will be destroyed due to excessive temperature. Moreover, the method of salting out will take away the glycerin and cannot completely retain the oil-alkali react...

Embodiment 1

[0024] This embodiment includes the following steps:

[0025] (1) Prepare alkali solution: mix sodium hydroxide and water at a mass ratio of 1:2, stir evenly while cooling, and control the solution temperature at 20-40°C;

[0026] (2) Purification of waste oil: remove impurities, separate and purify the waste oil; first put the waste oil into the waste oil cleaning machine, filter and remove the solid large particle impurities; then send the waste oil into the steam heating tank to heat and separate the heavy Components; then send the remaining light phase and impurities into the filter, filter out the impurities, and pass the filtered material into the oil-water separator for oil-water separation to obtain purified waste oil.

[0027] (3) Saponification: mix the waste oil purified in step (2) with the sodium hydroxide solution prepared in step (1) in a mass ratio of 100:15, control the temperature of the mixed solution at 30°C, and keep stirring with a stirrer, the stirring s...

Embodiment 2

[0033] The difference between this embodiment and embodiment 1 is that the temperature of the mixed solution in step (3) is controlled at 25° C.; the rest are basically the same as in embodiment 1.

[0034] The obtained soap has moderate hardness, many foams, strong cleaning ability, is not easy to oxidize, has a long storage time, has good use feeling and good moisturizing degree.

Embodiment 3

[0036] The difference between this embodiment and embodiment 1 is that the temperature of the mixed solution in step (3) is controlled at 20° C.; the rest are basically the same as in embodiment 1.

[0037] The obtained soap has moderate hardness, many foams, strong cleaning ability, is not easy to oxidize, has a long storage time, has good use feeling and good moisturizing degree.

Abstract

The invention discloses a method for manufacturing soap through gutter oil. The method includes the following steps that 1, aqueous alkali is prepared; 2, the gutter oil is purified; 3, saponification is conducted; 4, additives are added; 5, a primary product is formed; 6, aftertreatment is carried out. According to the method, the process is simple, safety and reliability are achieved, waste can be turned into wealth, and cost is low; the soap using feeling is excellent, the moisture preservation effect is good, and the moisture degree is sufficient; the hardness of the soap is moderate, the crystal structure is even, oxidation tends not to occur, and the retention time is long; foaming is liable to happen to the soap, foam is stable, and the cleaning capacity and the cleaning effect are improved.

Description

technical field [0001] The invention relates to a method for making soap, in particular to a method for making soap from waste oil. Background technique [0002] Due to the processing methods of Chinese dishes, the waste oil products in my country's kitchen waste are as high as 10 million tons or more every year. However, the huge waste oil resources have not been well developed and utilized. Instead, the waste oil is processed in large quantities every year. Returning to the dining table has aroused the attention of all walks of life, causing the government to introduce a large number of measures to prohibit and curb the use of waste oil, which in turn has caused the cost of social management to increase; at the same time, this returning to the dining table The behavior of the eater also poses a threat to the health of the eater. For this reason, a large amount of measures that prevent waste oil from returning to the dining table have begun to appear. However, these measure...
