In 2019, won the title of "Xinhai'an People"

The second use of supercritical carbon dioxide extraction in refrigerators. Environmental protection refrigerators are more advanced in terms of production technology and raw materials.

Supercritical extraction is to contact the supercritical fluid with the substance to be separated in the supercritical state, so that it can selectively extract the components of polarity, boiling point and molecular weight in sequence.

The application in the extraction of spices and pigments, the use of supercritical CO2 extraction technology to extract essential oils from flowers, fruit peels, edible spices, etc., can also extract other flavor substances, such as gingerol in ginger, piperine in pepper, Capsaicin in peppers, among them, the extraction of volatile oil and humulone from hops is the most successful industrial application of supercritical extraction.
