Compared to foreign color machine industry, color machine industry in China started relatively late, but development is very rapid, from the initial dependent on imports, to break the foreign technology monopoly implementation localization, to continuously improve products and technology, innovation, color machine industry in China has realized leap-forward development. Until the 1990 s, China's food processing required color separator mainly depends on import, monk of expensive products is not perfect after-sale service seriously affect the development of the domestic food processing industry, which makes the development of domestic demand color separator is imminent. In mid and late 90 s, domestic private capital into color machine research and development, manufacturing, after years of hard study and research, so far, domestic companies have mastered the core technology of production of color machine, the product gradually occupied more than 70% of the country's domestic market share. As the industry enterprises in color choose mechanical r&d investment amount and proportion of growing, promoting technology innovation, product performance gradually catch up with even more than the same products abroad.
