Problems solved by technology

[0003] In recent years, Japan, South Korea and Southeast Asian countries have put forward dewaxing requirements for high-grade edible sesame oil from mainland China, and wax is a fat formed by high-grade waterproof and high-grade fatty alcohols, including some high-grade free fatty acids, high-grade free fatty alcohols and hydrocarbons. Dewaxing is to make the sesame oil better edible and improve its edible quality, but the existing dewaxing steps are cumbersome, and its crystallization efficiency is not high during the dewaxing process, which affects the efficiency of its dewaxing

Embodiment 1

[0023] The invention provides a kind of preparation method of dewaxed sesame oil, comprises the following steps:

[0024] S1. Squeeze into oil: Send the sesame to the hydraulic oil press for pressing, and separate the filter residue and crude oil through the decanter separator;

[0025] S2, crude oil filtration: the crude oil obtained in S1 is left to settle, and after the sedimentation is completed, it is finely filtered through a blade filter to obtain filtered refined oil;

[0026] S3. Degumming, decolorization and deodorization: send the filtered refined oil into the refining pot for degumming treatment, and after the treatment is completed, send it to the decolorization tower and deodorization tower at one time for decolorization and deodorization treatment. Complete to obtain primary product oil;

[0027] S4. Stirring and cooling: send the primary oil into a crystallization tank for cooling at 0.5°C per hour, and stir at a low speed during the cooling process to slowly ...

Abstract

The invention discloses a preparation method of dewaxed sesame oil. The preparation method comprises the following steps: squeezing into oil; filtering crude oil; degumming, decoloring and deodorizing; stirring and cooling; crystallization and crystal growing: after the primary oil is cooled to a certain temperature in the crystallizing tank, starting to stop stirring, transferring the primary oil into a crystal growing tank, continuing crystal growing and crystallizing, and filtering, namely pumping the primary oil subjected to crystallization and crystal growing in the step S5 into a plate-and-frame filter for filtering, enabling filtrate to flow into a dewaxing clean oil tank when the filtrate is cleaned, pumping out the filtrate by a pump, passing through a polishing filter, and pumping the filtrate into a finished oil tank. According to the preparation method of the dewaxed sesame oil, the cooling rate can be adjusted, the crystallization rate can be better controlled, the dewaxing process of the primary product oil can be carried out more quickly, the dewaxing efficiency is better, and the dewaxed finished product sesame oil is clear, transparent and good in finished product quality.

Description

technical field [0001] The invention belongs to the technical field of sesame oil processing, and in particular relates to a preparation method of dewaxed sesame oil. Background technique [0002] Sesame oil, referred to as sesame oil, also known as sesame oil, is a kind of edible vegetable oil processed with sesame as the main raw material. Sesame oil has a strong and remarkable fragrance, which is used in seasoning of various cold dishes and delicacies. Sesame oil can promote people's appetite. Simultaneously, sesame oil is a very important food industry raw material, such as sesame tofu, sesame milk and other foods. Sesame oil can also be used in other industrial sectors, such as making lubricating oil, ointment, soap, etc. The fatty acids in sesame oil generally contain 35.0-49.4% oleic acid, 37.7-48.4% linoleic acid, and 0.4-1.2% arachidic acid. The digestion and absorption rate of sesame oil reaches 98%. [0003] In recent years, Japan, South Korea and Southeast As...
