Abstract

The invention discloses a tung oil extraction method. The method comprises the following steps: P1, oil tung green fruits are placed in a de-seeding machine, such that the fruits are shelled, and seeds are obtained; P2, the tung seeds obtained after shelling are preliminarily pressed and crushed; P3, the tung seed particles obtained in the preliminary pressing and crushing process is placed in a drying machine, and is heated and dried; P4, the heated and dried tung seeds are pressed in a pressing machine, such that tung oil is obtained; P5, the tung oil is filtered; P6, the obtained tung oil is heated to a temperature of 70-75 DEG C; P7, the heated tung oil is delivered to a vacuum extraction device, such that water and impurities are extracted under vacuum; P8, the tung oil is delivered to a precipitation tower and is subjected to one-step precipitation, such that refined tung oil is obtained. The de-seeding machine and the drying machine adopted by the invention have the advantages of simple structures and convenient application, such that labor resource can be saved, labor intensity can be reduced, efficiency can be improved, and the need of large-scale production can be satisfied. With the method, the refined tung oil has high quality, light color and low impurity content, and reaches national standards.

Description

technical field [0001] The invention relates to a method for refining tung oil. Background technique [0002] Tung is a deciduous tree with gray bark, thick branches, oval leaves, monoecious flowers, calyx densely covered with brown puberulent; petals white, with light red veins, obovate, ovary densely pilose , the drupe is nearly spherical, the seed coat is woody, and the flowering and fruiting period is from March to September; the seed has a thick shell-like testa, wide ovate; the kernel contains oil, up to 70%. Tung oil is an important industrial oil, making paints and coatings, economical The value is extremely high; tung oil and wood oil are golden or brown in color, both are excellent dry oils, shiny, inedible, with impermeable, airtight, non-conductive, acid and alkali resistance, corrosion resistance, cold and heat resistance, etc. Features: widely used in paint, plastics, electrical appliances, artificial rubber, artificial leather, artificial gasoline, ink and ot...
