Problems solved by technology

[0008] (1) The obtained wood wax oil still has the problems of poor color and more impurities;
[0009] (2) The solvent consumes a lot and the energy consumption of separation and recovery is high. The solvent is volatile, flammable, explosive, toxic, and unsafe to use;
[0010] (3) By-products are difficult to utilize and have low added value;
[0011] (4) The process is more complicated, more equipment is used, and the equipment cost is higher;

Abstract

The invention discloses a wood wax oil preparation method. The wood wax oil preparation method is characterized in that lacquer tree seeds are screened and washed, and then crushing, skin-core separation, seed-skin pretreatment, solvent extraction, filtration and separation are performed so as to finally obtain the lacquer tree seed wood wax oil. The preparation method for the lacquer tree seed wood wax oil enables the preparation, the extraction and the separation of the lacquer tree seed wood wax oil to realize continuous production, improves production efficiency, a raw material utilizationrate, wood wax purity and quality and wood wax market competitiveness. The method is used, so that lacquer tree seed skin-core separating efficiency reaches 97% or above, the lacquer tree seed core perfectness ratio reaches 94% or above, and effective utilization of byproducts is facilitated.

Description

technical field [0001] The invention relates to the field of plant resource processing, in particular to a preparation method of wood wax oil. Background technique [0002] Sumac seeds are renewable resources with high development value. The wax content of tree seeds reaches more than 35%, which mainly exists in the pulp part, usually called the wax layer. The wax contained in it has a melting point of 50-55°C and is solid at room temperature. It is purified and refined into Chinese wood wax. The lacquer seed core is almost free of wax, with an oil content of 12%-15%. The extract is liquid at room temperature, and the content of unsaturated fatty acids (oleic acid, linoleic acid) is as high as 80%. It is a good edible vegetable oil. The crude protein content of lacquer seeds reaches 20%, the crude fiber content reaches 19%, and the protein and crude fiber content of its cake is higher than 31%, which is a high-quality feed source. [0003] Japan is a pioneer in the develop...
