Ni Qin, a forest chemist from Dongfeng Forest Farm, Ito Bureau of Forestry in Heilongjiang Province, created a method for refining rosin using water as solvent and a large iron pan as a distillation pot by using Akiko soil method in late June and is now being promoted in Yichun. According to the proof of production practice, native soil refining rosin is characterized by: simple equipment (with a large iron pan can produce), easy to operate, and not subject to seasonal restrictions, can be produced for many years. Songgen Akiko now refining rosin production process described below. First, collect raw materials: raw materials mainly pine root Akiko, is in three years
