Latest Patents

Weixing Li holds a patent for a cleaning process of producing lactic acid. This process involves several steps, starting with the preparation of saccharification liquid from saccharated materials. The liquid is then fermented with nutritive materials and lactic acid bacteria, with liquid alkali used to adjust the pH. The fermentation broth undergoes filtration through a porous membrane, allowing for the recycling of lactic acid bacteria. The permeate is subjected to nanofiltration for decolorization and purification. The concentrated solution and cleaning liquid are then sterilized using ceramic membranes before being reintroduced into the fermentation unit. Finally, the lactic acid is concentrated through vacuum distillation. This process is characterized by low material consumption, reduced pollution, and environmental protection.
