Embodiment 1

[0024] The processing technology of freeze-dried decoction pieces of Dendrobium nobile, including the following steps:

[0025] (1) Grading: The fresh Dendrobium nobile is classified according to the number of stem nodes, 10-13 nodes / root are the first grade; 7-9 nodes / root are the second grade; 6 nodes / root and below are the third grade, so that Ensure the consistency of further processing;

[0026] (2) Cleaning: Pack the classified fresh Dendrobium nobile products in polypropylene woven bags, put them in the cleaning tank for 2 to 3 days, control the temperature within 25℃±5℃, take them out and put them in the washing machine Wash and drain the water for later use;

[0027] (3) Pretreatment: Put the drained Dendrobium nobile into a microwave dryer, microwave treatment for 1±0.5 minutes, and make the skin transparent and the color darker;

[0028] (4) Cut in sections: The cool Dendrobium nobile is divided into 3 sections according to the top, middle, and near roots. The top and midd...

Embodiment 2

[0034] The infiltration in step (2) in Example 1 was changed from 2 to 3 days to 3 to 5 days, and the temperature was controlled within 25°C±5°C to 10°C±5°C; the rest were the same as in Example 1.

Embodiment 3

[0036] Change the microwave treatment of 1±0.5 minutes in step (3) in Example 1 to 2±0.5 minutes of microwave treatment; the rest are the same as in Example 1.

Abstract

A process for microwave-freeze-drying dendrobium stem decoction medicine pieces comprises the steps of grading, wherein fresh dendrobium stems are divided into three grades according to the number of stem sections; cleaning, wherein the graded dendrobium stems are cleaned separately and drained off to be reserved; preprocessing, wherein the dendrobium stems which are drained off are placed into a microwave dryer and subjected to microwave processing for 1-3+/-0.5 minutes; segmented cutting, wherein each cooled dendrobium stem is divided into three segments according to the top, the middle portion and the root portion, and the top and the middle portion of each dendrobium stem are cut into thin sheets with the thickness from one mm to four mm; pre-freezing, wherein the cut dendrobium stem thin sheets are placed into a freezer and pre-frozen at the temperature from minus 10 DEG C to minus 20 DEG C for more than four hours; freeze-drying, wherein the cold trap temperature of a freezer dryer is lowered to be within the range of minus 55 DEG C to minus 65 DEG C for four to six hours, the pre-frozen dendrobium stem thin sheets are placed in the freezer dryer, and after sublimation is over and the temperature of a material disk returns to 20 DEG C, materials can be taken off after the temperature is kept at 20 DEG C for two to three hours, and then the dendrobium stem decoction medicine pieces are obtained.

Description

Technical field [0001] The invention relates to a processing technology of Dendrobium nobile, in particular to a processing technology of microwave-freeze-dried decoction pieces of Dendrobium nobile, and belongs to the technical field of processing and processing of decoction pieces of Chinese medicinal materials. Background technique [0002] Dendrobium nobile has the effects of nourishing yin and clearing heat, replenishing stomach, nourishing fluid, moistening lungs and relieving cough, etc. It has high medicinal value and health care functions. In recent years, the demand for medicines and health care products has increased year by year. Dendrobium nobile is listed as a national rare and endangered medicinal plant species. It is the main characteristic high-quality medicinal material in Guizhou, especially Chishui, the main producing area. It occupies more than 70% of the market share of Dendrobium nobile medicinal material and has been protected by the national geographica...
