Production method of high-quality pseudo-ginseng decoction pieces

Abstract

The invention discloses a production method of high-quality pseudo-ginseng decoction pieces. The production method comprises the following steps of digging pseudo-ginseng, and performing preliminary cleaning on the dug fresh pseudo-ginseng; performing preliminary drying on the pseudo-ginseng after being subjected to preliminary cleaning; performing vacuum freeze drying on the pseudo-ginseng afterbeing subjected to preliminary drying, wherein the vacuum freeze drying comprises a quick-freezing stage, a sublimation stage and an analysis drying stage, the quick-freezing stage comprises the following steps of loading the pseudo-ginseng after being subjected to preliminary drying into a material disk in a tiling manner, freezing materials to minus 40-50 DEG C, and performing heat insulation for 3-5 hours; the sublimation stage comprises the following steps of starting a cold trap ice catching system of a freeze dryer, so that the temperature is reduced to minus 70-80 DEG C, then starting asublimation procedure, then starting a material heating system, turning on a disc valve between a material bin and a cold trap, enabling a sublimation drying process to begin, and maintaining sublimation until a eutectic crystal resistor shows 20M omega; and the analysis drying stage comprises the following steps of controlling the freeze dryer to heat the materials to 40-45 DEG C, and performingheat insulation until a crystal resistor shows 30M omega; and performing fluidized drying and vacuum band drying on pseudo-ginseng after being subjected to vacuum freeze drying.

Description

technical field [0001] The invention relates to a production method of notoginseng, in particular to a production method of high-quality notoginseng decoction pieces. Background technique [0002] Panax notoginseng is a traditional precious Chinese medicinal material in my country. It is mainly produced in Wenshan, Yunnan, at the junction of Guangxi and Yunnan. It has a history of more than 400 years of use. It has medicinal effects such as promoting blood circulation and removing blood stasis, stopping bleeding and reducing swelling. important constituents. Modern medical research shows that Panax notoginseng also has a wide range of physiological health functions such as anti-aging, anti-fatigue, anti-atherosclerosis, anti-tumor, lowering blood pressure, lowering blood sugar, calming the nerves, enhancing immunity and beautifying. important resource. [0003] In recent years, due to the imbalance between supply and demand due to the huge demand, the number of people plant...

AI Technical Summary

Problems solved by technology

[0003] In recent years, due to the imbalance between supply and demand due to the huge demand, the number of people planting Panax notoginseng has expanded, and the planting area has expanded, forming a small, scattered, and chaotic situation. Selection, management of water and fertilizer use, pest control methods, and improper use of pesticides have resulted in uneven quality of Panax notoginseng medicinal materials on the market. Some commercial Panax notoginseng pesticide residues have high heavy metal content and poor safety in use

In addition, due to the limitations of funds, concepts, experience and technology, most growers can only work in fields, fields, roads, open-air drying yards and other places for pruning, grading and drying after excavation.

With this traditional extensive operation method, the wounds left by pruning on the main root of fresh Panax notoginseng will definitely absorb foreign matter during the drying process for dozens of days, which will bring "secondary pollution" to Panax notoginseng products

Secondly, it has been found through research that the active ingredients such as saponins, flavonoids, notoginseng and volatile oils contained in the dried Panax notoginseng can be easily destroyed by the traditional sun-dried or roasted processing method, which will affect the medicinal value and curative effect of Panax notoginseng , and a certain amount of soil and other impurities are also adsorbed on its surface. After most consumers buy Sanqi in the market, they directly powder it without treatment. The curative effect and safety are poor, and the safety risk is also large.
