The so-called 7D actually refers to the 7 original craftsmanship. Take this 7D rapeseed oil as an example. After the fresh rapeseed is poured into the oil pressing equipment, after the green processes of selection, tempering and aroma, low-temperature pressing and refining, it will immediately turn into bright-colored rapeseed oil. . The team of developers stated that the invention of the 7D rapeseed oil process also gave birth to a complete set of equipment for the processing of coriander oil, achieving standardization of processing technology, complete equipment, automation of production control, and technical engineering.

　　Unlike other processes for squeezing rapeseed oil, 7D rapeseed oil is produced without any chemical additions and no three wastes, which is absolutely green and environmentally friendly. Not only that, compared with the traditional oil pressing process, the new 7D process has also reduced the number of processes by more than 50%, the energy consumption has been reduced by more than 20%, and the production cost has been reduced by more than 30%. The functional rapeseed oil produced is not only safe The retention rate of nutrients, total phenols, vitamin E and other accompanying substances has also reached over 85%.
