Problems solved by technology

Similarly, the energy consumption of such a process is still relatively high, and there is sewage discharge, which will cause environmental pollution, and the production efficiency is low, and the quality of the produced products is not stable at the same time.
At present, the saponification process adopted by some large companies is a continuous saponification process in which oil is hydrolyzed into fatty acids, then purified by distillation, and then neutralized with alkali. The quality of the products produced in this way is stable and the production efficiency is also high. and distillation process, which makes the production cost very high

Abstract

The invention relates to the technical field of soap making, and particularly relates to a method for fast and continuously saponifying grease. The method sequentially comprises the following steps: A, blending, namely uniformly mixing the grease and fatty acid in proportion to obtain mixed liquor; B, saponification, namely respectively heating the mixed liquor and liquid caustic soda, mixing the heated mixed liquor and the heated liquid caustic soda to carry out saponification reaction, and adding to a brine solution with an additive so as to obtain a soap base after the saponification reaction is completed; C, soap pellet forming, namely carrying out vacuum spray drying, extrusion, homogenization, refining and pellet cutting on the soap base to obtain a soap pellet, wherein 60-80 parts by weight of the grease and 20-40 parts by weight of the fatty acid are fed. The saponification method disclosed by the invention has the advantages of continuity, stability, fast reaction rate, short reaction time, high production efficiency, less energy consumption, low production cost and large-scale industrial production.

Description

technical field [0001] The invention relates to the field of oil saponification, in particular to a method for rapid and continuous saponification of oil. Background technique [0002] Saponification reaction usually refers to the reaction of base (usually strong base) and ester to produce alcohol and carboxylate, especially the reaction of oil and base. In a narrow sense, the saponification reaction is limited to the reaction of oil mixed with sodium hydroxide or potassium hydroxide to obtain sodium / potassium salts of higher fatty acids and glycerin. This reaction is a step in the soap-making process, hence the name. [0003] In the oil industry, the traditional saponification method is the method of boiling soap in a large pot. This method consumes high raw materials, has low production efficiency and unstable product quality, and is gradually being eliminated. There is a conventional oil continuous saponification process, which continuously converts oil, caustic soda an...
