Problems solved by technology

However, since the refining of mixed oil is carried out in the leaching workshop, all equipment must be explosion-proof and non-leakage. Nitrogen treatment must be carried out when starting and stopping, and corresponding fire-fighting facilities must be provided. This is very difficult for ordinary factories. of
Secondly, centrifuges have relatively strict requirements on impurities in crude oil. Foreign centrifuges generally require that the impurity content be below 0.2%, which is difficult for general factories to achieve. At the same time, the drum must be cleaned regularly, which virtually increases solvent consumption and causes production Increased costs

Abstract

The invention discloses a method for refining kernel oil of lacquer tree seeds. The method comprises the steps of: lacquer tree seed freezing, peel-nucleus separation, screening, pressing, leaching, desolvation, extraction and merging, desolvation is conducted through a membrane evaporator by using a high-vacuum membrane evaporation mode, and extraction is conducted through supercritical carbon dioxide extraction. The invention also provides the lacquer tree seed kernel oil prepared by using the method, and the method for refining the kernel oil of lacquer tree seeds has a simple and convenient process; the lacquer tree seed kernel oil extracted by using the method has high purity, and denaturation of free urushiol is avoided, so that the color, quality and use performance of the oil are good, the production cost is greatly reduced, and the refining loss rate of the lacquer tree seed kernel oil is reduced; and therefore, the method is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of preparation methods of edible oils and fats, more specifically, to the technical field of a refining process of sumac seed kernel oil, in particular to a refining method of sumac seed kernel oil. Background technique [0002] The lacquer tree is a kind of economic forest that is full of treasures. As we all know, lacquered wood is a high-quality wood that is resistant to corrosion and moisture; raw lacquer produced from lacquer trees is an important raw material for the production of ultra-durable anti-corrosion coatings, ecological high-grade urushiol furniture lacquer, exquisite lacquer, lacquer furniture, raw lacquer wood floor strips, etc., and is currently the only The natural, renewable, and excellent performance bio-based coatings have the reputation of "the king of coatings"; the leaves, flowers, fruits and dry lacquer of sumac trees are all traditional Chinese medicinal materials. Sumac seeds ha...
