Problems solved by technology

Taking the production of garlic essential oil as an example, the traditional steam distillation method or solvent extraction method is mainly used at present. These two methods have complicated procedures, large loss, low oil yield, low product purity, and require appropriate temperature, which is extremely easy to lose effective oil. Active ingredients, recently advanced supercritical CO 2 Extraction technology extracts garlic essential oil, avoiding the above-mentioned disadvantages
However, the above-mentioned technologies are seldom used in the research and application of waste water and garlic residue, and it is difficult to realize a comprehensive high value-added processing system, which leads to poor economic benefits and even difficulty for enterprises to survive.

Abstract

The invention provides a method for extracting garlic essential oil and cogenerating garlic amylose and garlic powder. The garlic essential oil is extracted by the static extraction of an extraction kettle and by the dynamic extraction of a second class separation kettle by supercritical CO2, the garlic amylose is extracted from garlic residues continuously, and finally, the garlic residues are processed into the garlic powder. A cogenerating production technology is used for producing three products of the garlic essential oil, the garlic amylose and the garlic powder at the same time by just feeding once, which changes the current situation that the products produced in the fine and further processing of the garlic is single; the invention uses a raw material comprehensively and realizes the production of the garlic with high added value; the key technical points are controlled during the production process, so the yield is high, the utilization of the raw material is approximately 100 percent, the yield is high, the oil yield is 0.5 to 0.7 percent, 98 percent of the garlic amylose in the raw material is recovered, and all the garlic residues are used. The production process does not relate to toxic or harmful reagent, which solves the problem of serious pollution in the current production and realizes the clean production without waste materials and waste water discharge.
