Embodiment 1

[0026] A fast drying processing method for American ginseng, comprising the following steps:

[0027](1): Select American ginseng without mildew and mechanical damage, embed the part below the reed head of American ginseng with soil or wrap the whole ginseng with soil, and place it in a low-temperature and high-humidity environment with a temperature of 1°C and a relative humidity of 75%. lower storage;

[0028] (2): Remove the roots and reed heads of the stored American ginseng, and clean the sediment on the surface with clean water and drain the residual water on the surface;

[0029] (3): Cut the cleaned American ginseng into thin slices with a thickness of 1.5mm along the transverse direction;

[0030] (4): Lay the cut American ginseng slices in a single layer on the gas jet impact drying tray for gas jet impact drying. The drying temperature of the first drying section is 45°C and the drying wind speed is 9m / s. When the moisture content of the wet basis drops to 65%, en...

Embodiment 2

[0033] A fast drying processing method for American ginseng, comprising the following steps:

[0034] (1): Select American ginseng without mildew and mechanical damage, embed the part below the reed head of American ginseng with soil or wrap the whole ginseng with soil, and put it in a low temperature and high humidity environment with a temperature of 6°C and a relative humidity of 100%. lower storage;

[0035] (2): Remove the roots and reed heads of the stored American ginseng, and clean the sediment on the surface with clean water and drain the residual water on the surface;

[0036] (3): Cut the cleaned American ginseng into thin slices with a thickness of 3.5mm along the transverse direction;

[0037] (4): Lay the cut American ginseng slices in a single layer on the gas jet impact drying tray for gas jet impact drying. The drying temperature of the first drying section is 60°C and the drying wind speed is 20m / s. When the moisture content of the wet basis drops to 50%, i...

Embodiment 3

[0040] A fast drying processing method for American ginseng, comprising the following steps:

[0041] (1): Select American ginseng without mildew and mechanical damage, embed the part below the reed head of American ginseng with soil or wrap the whole ginseng with soil and place it in a low temperature and high temperature with a temperature of 3-5°C and a relative humidity of 90-100%. Store in a humid environment for no more than 4 months.

[0042] (2): remove the roots and reed heads of the stored American ginseng or fresh American ginseng, and clean the sediment on the surface with clean water and drain the remaining water on the surface;

[0043] (3): Cut the cleaned American ginseng into thin slices with a thickness of 2mm along the transverse direction;

[0044] (4): Spread the cut American ginseng slices in a single layer on the gas jet impact drying tray, and perform gas jet impact drying. The drying temperature of the first drying section is 55°C and the drying wind ...

Abstract

The invention discloses a rapid drying processing method of American ginseng and belongs to the technical field of agricultural product processing. The method comprises the following operation steps: storing the American ginseng in a low temperature and high moisture environment; cleaning the American ginseng with root hairs and rhizomes removed; slicing; carrying out gas jet impingement drying with changed temperature and wind speed; and carrying out nitrogen-filled package. The invention employs the gas jet impingement technology to dry the American ginseng sheets, has fast drying and dehydration speed, high production efficiency and short processing time; temperature changing and wind speed changing drying is employed according to drying characteristics of the material and has advantages of low heat-sensitive component loss and low energy consumption; and the product is not treated with dry sulphitation and natural and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a drying processing method of American ginseng. Background technique [0002] American ginseng is a perennial herb of Araliaceae Panax genus. The dried root is used as medicine. The crude drug is called American ginseng, American ginseng or American ginseng. American ginseng contains ginsenosides, volatile oils, polysaccharides and other biologically active ingredients, which have the functions of nourishing and strengthening the body, benefiting the lungs and yin, clearing deficiency fire, nourishing blood and promoting body fluid, calming the nerves and improving intelligence. my country has successfully planted American ginseng in Heilongjiang Province since 1975. After more than 30 years of continuous improvement, it has formed a complete set of technical systems from seed treatment, planting management, plant protection, improved seed bree...
