Problems solved by technology

[0005] In order to solve the most suitable slice conditions in the processing process of licorice origin and the lack of corresponding temperature parameters in the drying process, the present invention compares slices with different water contents with traditional slices through experiments on fresh slices of licorice. The content of active ingredients glycyrrhizic acid and liquiritin were used as indicators to determine the most suitable fresh-cut conditions for licorice; in addition, the optimal drying temperature range was determined by comparing licorice dried at different temperatures with traditional sun-dried licorice

Embodiment 1

[0010] Put the collected raw grass into a drum-type grass washer and rotate for about 10-15 minutes, chop, cut, and cut the washed licorice, and then classify and process into strips, wool grass, knot grass and lumps. When placed under environmental conditions, when the moisture content reaches 60%, cut it into 2-3mm thick slices with a slicer while it is fresh; dry until the moisture content is below 12%; blow the dust and grass residue powder in the slices with wind, etc. After dropping, repack it as required.

Embodiment 2

[0012] Similar to Example 1, the difference is that the collected raw grass is put into a drum-type grass washer and rotated for about 10-15 minutes, and the washed licorice is chopped, cut, and sheared, and then classified into strip grass, wool grass, and knot grass. And lump head, placed under the same environmental conditions after grading, when the water content reaches 40%, cut it into 2-3mm thick slices with a slicer while it is fresh; sun-dried until the water content is below 12%; slice it with wind, etc. After blowing off the dust and grass dregs in the powder, separate packaging as required.

Embodiment 3

[0014] Similar to Example 1, the difference is that the collected raw grass is put into a drum-type grass washer and rotated for about 10-15 minutes, and the washed licorice is chopped, cut, and sheared, and then classified into strip grass, wool grass, and knot grass. And lump head, placed under the same environmental conditions after grading, when the water content reaches 20%, cut it into 2-3mm thick slices with a slicer while it is fresh; sun-dried until the water content is below 12%; use wind etc. to slice After blowing off the dust and grass dregs in the powder, separate packaging as required.

Abstract

The invention provides a fresh-cut slice processing method of licorice. The fresh-cut slice processing method comprises following steps: harvested licorice is subjected to washing, cleansing, and direct fresh cutting, wherein thick slices with a thickness of 2 to 3mm are obtained via transverse cutting by using a slicer when water content of fresh licorice ranges from 12 to 60%; the fresh thick slices of licorice are dried in the air, or are delivered into an air dry oven to dry until water content is less than 12% at a temperature of 45 to 105 DEG C. The fresh-cut slice processing method is capable of avoiding infiltrating softening of conventional processing methods, reducing man-hour and processing cost, and ensuring medicinal material quality as far as possible; and is suitable for primary processing of large scale sliced licorice.

Description

1. Technical Field [0001] The invention relates to the technical field of medicine, in particular to a fresh slice processing method of the licorice herbal material for setting the technical parameters of the licorice herbal material slicing and drying link. 2. Background technology [0002] Licorice is the dried roots and rhizomes of the leguminous plant Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat. or Glycyrrhiza glabra L. (Chinese Pharmacopoeia 2010 edition). Licorice is a common medicinal material. The main active ingredients contained in licorice are saponins such as glycyrrhizic acid and glycyrrhetinic acid, and flavonoids such as glycyrrhizin, glycyrrhizin, glycyrrhizin, and alkaloids. "Chinese Pharmacopoeia" (2010 edition) stipulates that the content of glycyrrhizin in licorice herbs should not be less than 0.50%, and glycyrrhizic acid should not be less than 2.0%. [0003] For many years, the traditional processing method of licorice slices is to dry the excavate...
