According to Professor Yun Zhi of Nanjing University of Technology, this intensive, co-produced new technology with independent intellectual property rights treats oily seeds with a dual-liquid extraction method, detoxifies at room temperature, and obtains non-toxic pancakes with good nutritional value. At the same time, non-polar solutions containing high-quality vegetable oils are used in transesterification reactions to produce lower-cost fatty acid esters and glycerol. This achievement uses two immiscible solvents to co-treat cottonseed, eliminating the high-temperature process in traditional cottonseed processing and avoiding denaturation of cottonseed protein, and has obtained the invention patent authorization.
The new process begins with oilseeds, and the overall consideration of oil extraction, detoxification of cakes, chemical conversion of oils, and the coupling of two different types of solvents are beneficial to systematically reducing production costs, as well as optimizing raw material, energy, and production plant configurations. Going to the refining process of the crude oil and the purchase, sale, transportation and warehousing of the intermediate product oil, the quality of the crude oil was significantly improved, which brought great convenience to the refinement of the fatty acid methyl ester and glycerin of the final product.
This technology has completely reformed the traditional oilseed processing pre-extraction leaching process, making the appearance and intrinsic quality of cotton aphid significantly improved. It can not only replace soybean meal and fish meal in feed, but also can extract high-purity protein for other purposes. industry. Industry experts said that the results provide a new way for low-cost production of biodiesel, and will promote China's large-scale traditional cottonseed processing enterprises to extend the industrial chain and increase economic efficiency. The popularization and application of this result is of great significance to the efficient and comprehensive utilization of a large number of genetically modified cottonseeds and other kinds of toxic oilseed resources yet to be developed in China each year.
Oilseed polygeneration technology adds value to the industry chain
The reporter recently learned from Nanjing University of Technology that the new technology developed by the university using cottonseeds as a raw material to produce diesel, glycerin and non-toxic cottonseed crude protein has reduced the production cost, improved the quality of crude oil, and reduced waste emission. The results are applicable to a variety of oilseeds and will help China ease the situation where energy and high-quality protein are heavily dependent on imports.
