Preparation method of active pseudo-ginseng slices

Abstract

The invention relates to a drying process method of a specific plant. The method comprises the following steps of: (1) pretreatment: sorting and selecting prepared fresh pseudo-ginseng, separating and removing snips, fibrous roots and flocking roots attached to the fresh pseudo-ginseng roots to obtain pseudo-ginseng main roots, cleaning and removing surface attachments, draining surface moisture, and cutting into 0.2-2 mm slices by using a slicing machine; (2) pre-freezing: directly placing the slices in a pre-freezing room with the set temperature of subzero 15 to subzero 20 DEG C, and pre-freezing for 5-6h; (3) sublimation drying: spreading the pre-frozen slices out on a desk tray made of a conducting material, controlling the spreading thickness to be below 5 cm, and moving to a vacuum drying room; sealing, starting vacuumizing, maintaining the internal vacuum pressure at 30-70 pascals, setting the temperature of the desk tray to be 40 DEG C, keeping supplying heat for the desk tray, and carrying out vacuum sublimation drying for 7-10h until the temperature of the desk try reaches 40 DEG C; (4) analysis: maintaining the temperature of the desk tray to be 40 DEG C, keeping supplying heat for the desk tray and vacuumizing for 6-12h until the temperature of the material reaches 40 DEG C, and controlling the moisture of the material at 3-5%; and (5) discharging and packaging.

Description

technical field [0001] The invention relates to a drying process for specific plants. Background technique [0002] Panax notoginseng is a traditional Chinese herbal medicine in my country. In addition to the medicinal effects of promoting blood circulation and removing blood stasis, hemostasis and detumescence, modern research shows that Panax notoginseng also has anti-aging, anti-fatigue, anti-atherosclerosis, anti-tumor, lowering blood pressure, lowering blood sugar, calming the nerves, strengthening It has a wide range of physiological health functions such as immunity and beauty, and is a very valuable health food resource for development. However, due to the traditional processing method (fresh notoginseng after excavation is dried naturally or baked in a barn), the notoginseng processed is too hard and difficult to crush, which makes it inconvenient for families and individuals to use for themselves, and the taste is too bitter, which restricts Promote the applicati...

Problems solved by technology

In this patent application, the processing time of fresh notoginseng in the whole process of producing active notoginseng is too long, and the energy consumption is too high; the analysis temperature is as high as 120°C, and the "active notoginseng" prepared at this temperature is very It is difficult to maintain the basic activity of fresh Panax notoginseng, and it will cause the coking of Panax notoginseng
