Abstract

The invention relates to the technical field of rosin production, in particular to a rosin processing method. The rosin processing method specifically includes steps: smashing rosin; adding a solvent; melting, and roughly filtering; performing tangential flow film separation; distilling; cooling to obtain solid-state rosin. By adopting the rosin processing method, impurity ingredients in rosin can be removed effectively, and the obtained solid-state rosin is shallow and uniform in color and high in purity.

Description

technical field [0001] The invention relates to the technical field of rosin production, in particular to a processing method of rosin. Background technique [0002] Rosin is one of the most productive natural resins in nature. It has excellent physical and chemical properties and is an indispensable raw material for many industries such as papermaking, paint, ink, matches, rubber, electrical appliances, medicine, and textiles. Rosin is a non-volatile natural resin obtained from pine rosin through different processing methods. After the xylem of slash pine and masson pine is damaged, a lot of turpentine will flow out from the wound. These pine resins will be severely oxidized into yellow, brown or black solids during long-term contact with the air, and their physical and chemical properties are quite different from fresh rosin, and rosin is in the process of accumulating and gathering with many barks. Impurities and silt stick together and are difficult to remove. Rosin c...
