Abstract
The invention discloses a preparation method of tung oil. The preparation method comprises P1, putting tung tree green fruits into a de-seeding machine and carrying out husking and seed collection, P2, carrying out primary pressing on the tung tree seeds obtained by husking to break the seeds, P3, screening the tung tree seeds obtained by primary pressing seed breaking, P4, putting the screened qualified tung tree seeds into a drying machine and carrying out heating drying, P5, putting the heated and dried tung tree seeds into a squeezing machine and carrying out squeezing to obtain tung oil, P6, filtering the tung oil, P7, heating the filtered tung oil to 75-80 DEG C, P8, conveying the heated tung oil into a vacuum pumping device and carrying out vacuum water and impurity pumping, and P9, conveying the tung oil into a settling tower, carrying out further precipitation and carrying out refining to obtain refined tung oil. The de-seeding machine and the dryer used by the preparation method have simple structures, are convenient in use, save labor resources, reduce labor intensity, improve efficiency and meet the needs of large-scale production. The refined tung oil obtained by the preparation method has high quality, is in a light color, has low content of impurities and satisfies national standards.
Description
technical field [0001] The invention relates to a preparation method of 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 ...
