Embodiment 1

[0022] A preparation method of dendrobium tea is made from dendrobium as raw material, comprising the following steps:

[0023] (1) After the dendrobium is harvested, it is washed, cut into sections, and baked in a constant temperature drying room at a temperature of 60°C for 16 hours;

[0024] (2) Microwave treatment after leaving the drying room for about 2.5 minutes to obtain dry tea;

[0025] (3) Add 4 times the amount of water to the dry tea obtained in step (2), adjust the pH=7 with NaOH, decoct for 1 hour, collect the filtrate, add 3 times the amount of water to the filter residue, decoct for 0.5 hours, collect the filtrate, and combine the filtrates;

[0026] (4) Concentrate the filtrate obtained in step (3) at 70°C to a relative density of 1.1, and add ethanol until the alcohol content is 65%;

[0027] (5) Stand still for 12 hours, filter, take the supernatant to recover ethanol and concentrate to obtain Dendrobium extract;

[0028] (6) Use fluidized bed drying or m...

Embodiment 2

[0030] A preparation method of dendrobium tea is made from dendrobium as raw material, comprising the following steps:

[0031] (1) After the Dendrobium is harvested, it is washed, cut into sections, and baked in a constant temperature oven at a temperature of 65°C for 17 hours;

[0032] (2) Microwave treatment after leaving the drying room for about 3 minutes to obtain dry tea;

[0033] (3) Add 8 times the amount of water to the dry tea obtained in step (2), adjust the pH=9 with NaOH, decoct for 3 hours, collect the filtrate, add 6 times the amount of water to the filter residue, decoct for 2 hours, collect the filtrate, and combine the filtrates;

[0034] Evaporate and concentrate the filtrate obtained in step (3) to an extract, then dry it in a vacuum belt dryer to obtain a dry extract, then granulate and tablet to obtain plain tablets, and finally coat the plain tablets with a film to obtain tea lozenge;

[0035] (4) Concentrate the filtrate obtained in step (3) at 80°C ...

Embodiment 3

[0039] A preparation method of dendrobium tea is made from dendrobium as raw material, comprising the following steps:

[0040] (1) After the Dendrobium is harvested, it is washed, cut into sections, and baked in a constant temperature drying room at a temperature of 70°C for 18 hours;

[0041] (2) Microwave treatment after leaving the drying room for about 2.75 minutes to obtain dry tea;

[0042] (3) Add 5 times the amount of water to the dry tea obtained in step (2), adjust the pH=7.5 with NaOH, decoct for 1.5 hours, collect the filtrate, add 4 times the amount of water to the filter residue, decoct for 0.5 hours, collect the filtrate, and combine the filtrates ;

[0043] (4) Concentrate the filtrate obtained in step (3) at 75°C to a relative density of 1.1, and add ethanol to an alcohol content of 65%;

[0044] (5) Stand still for 12 hours, filter, take the supernatant to recover ethanol and concentrate to obtain Dendrobium extract;

[0045] The dendrobium extract in ste...

Abstract

The invention relates to a preparation method of herba dendrobii tea, which comprises the following steps: harvesting the herba dendrobii, washing, cutting into sections, and baking in a constant-temperature drying room; after taking the herba dendrobii out of the drying room, performing microwave treatment to obtain dry tea; adding water and decocting and mixing the filtrates; concentrating, standing and filtering to obtain a herba dendrobii extract; and drying, grinding, sieving, sterilizing and sub-packaging. The preparation method is scientific and reasonable and simple and easy to implement and has high production continuity; the types of the obtained medicinal tea are diverse, and the purity of the herba dendrobii extract is high; the baking temperature is moderate, the time is proper, and a good aroma extraction effect can be achieved; and the medicinal active ingredients of herba dendrobii tea can be maintained to the greatest degree, and the nutritional value is increased. The herba dendrobii tea prepared by the method provided by the invention has the functions of benefiting stomach, promoting fluid production, nourishing yin, clearing heat, resisting aging, improving immunity and the like and is easy to carry, convenient to use, nature and pureness and the like.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a preparation method of dendrobium tea. Background technique [0002] Dendrobium tea is a health tea mainly made from Dendrobium. Most of the dendrobium teas in the prior art are mostly obtained from the compatibility of dendrobium and other Chinese herbal medicines, and their respective corresponding preparation methods also have many improper parts, which easily cause problems such as nutritional loss, quality reduction, and unsatisfactory health care effects. [0003] A kind of dendrobium tea disclosed as CN101695328A is made from 3 to 7 parts of Dendrobium, 2 to 3 parts of Gynostemma pentaphyllum, 3 to 7 parts of cat's whiskers, 3 to 7 parts of tea leaves, and 3 to 5 parts of sugar; Soak Dendrobium and Gynostemma in water for 8 to 12 hours, heat and boil for 1 to 3 hours, then add tea leaves and cat's whiskers, continue to boil for 1 to 3 hours, and fil...
