Technical Field

The present invention relates to a method for preparing kinds of red ginseng paste and a heating furnace for vacuum concentration, and more particularly, to kinds of red ginseng concentrated paste prepared by subjecting dried red ginseng to processes such as water extraction, filtration, and concentration.

Background

Ginseng radix Rubri belongs to Araliaceae plant Ginseng radix (Panax ginseng C.A.Mey), and its main source is steamed dried root and rhizome. The producing areas are commonly seen in Liaoning provinces, Jilin provinces, Heilongjiang provinces and the like, and in addition, the provinces such as Hebei province, Shanxi province and inner Mongolia provinces are introduced and cultivated later. The root of ginseng contains mainly ginsenosides, sugar and polysaccharides, volatile components, organic acids and alcohols, etc. Ginsenoside is the main effective component of ginseng, wherein dammarane series triterpene saponin has the most remarkable activity and is a common component in traditional Chinese medicines. The conventional harvesting and processing method of Ginseng radix Rubri comprises picking in autumn, cleaning, steaming, and drying. During the preparation process, chemical components are changed correspondingly, wherein maltol, pyroglutamic acid, sterol fatty acid ester and glyceroglycolipid in red ginseng are all higher than those in sun-dried ginseng, and saponin components are degraded by alcohol bonds and glycoside bonds during the processing process.

Currently, the red ginseng products known to consumers in the society mainly include raw red ginseng, red ginseng slices, red ginseng paste, red ginseng powder, red ginseng concentrate, and the like. Although the original red ginseng and red ginseng slices maintain 100% of red ginseng components, the eating method is not convenient; although red ginseng powder is convenient to eat, it is difficult to maintain 100% of red ginseng component by its complicated processing. In contrast, the red ginseng concentrated solution is more suitable for the preference of consumers. The existing red ginseng concentrated solution is prepared by red ginseng through the processes of advancing, filtering, concentrating and the like, and has good water solubility. In a common red ginseng processing technology, multiple heating is needed, particularly in a steaming process, steaming is usually carried out at a high temperature of more than 100 ℃, the high-temperature steaming is easy to damage the structure of ginsenoside, so that the content of the main effective component of the ginsenoside is reduced, and the obtained product has poor sense and pungent smell.
