Problems solved by technology

[0003] After the sealwort is harvested, it needs to be processed into decoction pieces according to the actual needs, so as to facilitate storage, transportation, sub-packaging and clinical use; the traditional processing method of sealwort slices is generally cutting and drying, and the water content after processing is still 10-14%. Mildew may still occur during storage and transportation

Embodiment 1

[0019] Harvest 100kg of fresh sealwort, remove impurities such as sediment and stones, remove non-medicated parts and moldy parts of moths; adjust the drum speed of the medicine washing machine to 8r / min, put the sealwort into the medicine washing machine, and pressurize with drinking water Wash for 10 minutes; spray the medicine with drinking water for 2 minutes, and then moisten the medicine for 5 minutes; then cut Polygonatum into 8mm thick slices; put the slices into a vacuum freezer, the initial temperature in the freezer is -5°C, and then Drop to -20°C within 4 hours; then raise the temperature of the frozen Polygonatum section to 20°C and keep it for 4 hours; then lower the temperature to -50°C, start the vacuum and keep the vacuum at 20Pa for 10 hours; then heat , raising the temperature of the frozen Polygonatum slices to 20° C. and keeping it for 1 hour; finally vacuum-packing the freeze-dried Polygonatum slices with a vacuum packaging machine.

Abstract

A vacuum freeze-drying method of rhizoma polygonatum adopts a fresh-cutting vacuum freeze-drying method, and comprises the following steps: selecting, cleaning with drinking water under pressure, leaching with drugs, moistening with drugs, cutting rhizoma polygonatum into thick slices, putting the slices into a vacuum freezing tank for freezing, heating, starting freezing, keeping vacuum, heating, and performing vacuum packaging of the freeze-dried rhizoma polygonatum slices by a vacuum packaging machine; rhizoma polygonatum is cleaned and cut into slices; under a low-temperature condition, water in the rhizoma polygonatum condenses into ice-state water, and directly sublimate in vacuum, and the rhizoma polygonatum dehydrates; through detection, rhizoma polygonatum after vacuum freeze drying has an average water content of 4.82%, and the processed rhizoma polygonatum can be stored for a long time, and is not easy to mildew.

Description

technical field [0001] The invention belongs to a processing method of pure natural medicine, in particular to a vacuum freeze-drying method of sealwort. Background technique [0002] Polygonatum Polygonatum is a perennial herb of the Liliaceae Polygonatum genus, including Polygonatum Polygonatum, Polygonatum Polygonatum and Polygonatum multiflora, etc., and its dried rhizomes are used as medicine. According to the classic records of traditional medicine, Rhizoma Polygonatum belongs to the precious Chinese medicine, which has the effects of widening the middle and replenishing Qi, nourishing the kidney and replenishing essence, nourishing yin and moistening the lung, and promoting body fluid and nourishing the spleen. Indications dryness of the lungs and dry cough, physical weakness and fatigue, palpitations, shortness of breath, chronic illness, dry mouth, diabetes, high blood pressure and other diseases. It has good effects on the treatment of cardiovascular diseases, tub...
