Production process of semi-finished rosin with fallen pine resin

Abstract

The present invention discloses production process of semi-finished rosin with fallen pine resin. The technological process includes the steps of: dissolving, squeezing, washing and packing. The present invention has the advantages of simple squeezing method, low cost, high work efficiency, no solvent loss and high natural rosin effective component recovering rate up to 90 %.

Description

technical field [0001] The invention relates to a method for producing rosin, in particular to a method for producing semi-finished rosin by using natural rosin. Background technique [0002] Yunnan pine, slash pine, masson pine, Simao pine and other pine species are harmed by diseases and insect pests, the xylem is damaged, and a lot of rosin will flow out of the wound, which accumulates over time and gathers at the roots of pine trees. The invention is to collect this natural ground pine resin and process it into a semi-finished product of rosin. As the natural ground turpentine grows in contact with the air, the turpentine will continue to volatilize and turn into a yellow, brown or black solid. Due to the high content of oxides and impurities in natural turpentine, its physical and chemical properties are obviously different from fresh turpentine. Therefore adopt present conventional rosin production method and can't produce rosin product smoothly. 1. When processed by...

AI Technical Summary

Problems solved by technology

Therefore, the current conventional rosin production method cannot successfully produce rosin products.

1. When processed by conventional methods, the oxidized rosin becomes a kind of extremely viscous black jelly after being heated during the heating process. Heat conduction, resulting in the consequences of burning through the bottom of the pot, in severe cases, it will cause damage and loss to life and property

Production by the steam method will stick the sieve plate of the equipment, block the pipeline, and easily lead to safety accidents

2. Due to the poor air permeability of this jelly, it adheres to bark impurities and sediment when dissolving, and cannot be easily separated from impurities, so it is difficult to filter. There are many active ingredients in the filter residue, and the product recovery rate is low. The rate is only 20% of the raw material

3. Even if it needs to be processed by conventional methods, the production process is complicated, and a large amount of dissolution and filtration equipment needs to be added, and the investment is too large

The solvent loss is also large, and more than 0.3 tons of turpentine is consumed per ton of product
