Description
Technical field
The present invention relates to the drying means of a kind of scented tea, particularly to a kind of Herba Dendrobii flower classification drying means.
Background technology
Herba Dendrobii (Dendrobium officinale) is the orchid family Dendrobium herbaceos perennial, for " middle traditional Chinese medicines
Allusion quotation " traditional rare Chinese medicine of being included, it is distributed in Anhui, Guangxi, Guizhou, Yunnan and Zhejiang etc. at China's Major Natural and saves
District.Because it is rich in Multiple components such as polysaccharide, dendrobine, helio acid, clinic and Chinese medicine compound is widely used, there is enhancing body
Immunity, defying age, antitumor, expansion blood vessel and anti-platelet aggregation etc. act on, be therefore described as " China nine big Herba mesonae chinensis " it
First.The profit of great number causes wild resource the most exhausted, is then listed in the world two class and protects plant, special-protection-by-the-State medicinal
Plant and China Precious, Rare, Endangered second class protection plant.It is single that Herba Dendrobii series of products kind is sold in market at present, is mostly
Fresh bar and Herba Dendrobii extract, small part is the deep processed products such as extract, oral liquid, compound preparation, and is substantially Herba Dendrobii cane
Related product, Herba Dendrobii flower series products is less.Studies have found that Herba Dendrobii contains terpenoid, aliphatic category and the fragrance same clan in spending
Planting Deng compound more than 50, simultaneously rich in polysaccharide, aminoacid, flavone and polyphenol in it, and the reducing power of Herba Dendrobii flower is eager to excel
In Herba Dendrobii stem, the prospect of marketing is wide.
Herba Dendrobii flower is less, the florescence more concentrates, and workload of therefore gathering is bigger.Additionally Herba Dendrobii is spent dry at present
Dry mode disunity, lyophilization is preferable for the effect keeping flower pattern pattern and nutritional labeling, but high cost and dry
Dry required time is longer；Natural flash-off time is relatively long, and flower easily rots to go mouldy during this period；More conventional traditional method is
Baking and banking up with earth dry, but bake and bank up with earth in dry run, especially early stage flower moisture is relatively big, and major part bakes and banks up with earth equipment air draft dehumidifying effect
Limited, it is chronically at humid tropical condition in dehydrator, causes the Herba Dendrobii flower especially rapid blackening of petal, have a strong impact on dry
Pattern pool, condition and quality.Some processes employing 100 DEG C and temperatures above thereof complete, but in the practical operation of inventor
Finding that the method can make ambient temperature and humidity rise rapidly, the Herba Dendrobii flower after this temperature completes is affected general by hot and humid steaming and decocting
All over presenting curing state, dried flower blackening, nutritional labeling and scented tea outward appearance are the most impacted.
The information being disclosed in this background section is merely intended to increase the understanding of the general background to the present invention, and should not
When being considered to recognize or imply in any form this information structure prior art well known to persons skilled in the art.
Summary of the invention
The present invention in above-mentioned prior art, the Herba Dendrobii flower dry run existed is spent easy blackening, nutrition or
Effective ingredient minimizing, technological process length, problem that energy consumption is high, it is provided that a kind of Herba Dendrobii flower classification drying means, it is intended to obtain
A kind of flow process is simple and direct, and energy consumption is low, can be effectively retained Herba Dendrobii flower pattern simultaneously and spend interior effective or battalion in dry run
The drying means formed point.
For achieving the above object, the technical scheme that the present invention provides is as follows:
A kind of Herba Dendrobii flower classification drying means, comprises following operating procedure:
(1) the Herba Dendrobii flower collected is classified by flower and bud, then carry out pretreatment；Wherein, flower refers to
Be the Herba Dendrobii flower launched, bud refers to not deployed Herba Dendrobii flower；
(2) gained Herba Dendrobii flower after pretreatment in step (1) being carried out hot air drying, baking temperature is 50～70
DEG C, dehumidifier, front the 2～3h of dehumidifier every 10～15min, dehumidifier 1～3min, be adjusted to every 20～30min after 2～3h again,
Dehumidifier 1～3min, it is ensured that drying room internal gas need to all be changed by dehumidifier every time, hot air drying 8～10h obtains Herba Dendrobii
Dry flower；
(3) gained Herba Dendrobii bud after pretreatment in step (1) is carried out lyophilization, baking temperature be-60～-
50 DEG C, vacuum is 0.020～0.050mbar, is dried 24～32h, obtains Herba Dendrobii dry flower.
Wherein, also include that step (4) encapsulates and preserves: by step (2) hot air drying gained Herba Dendrobii flower and step
(3) lyophilization gained Herba Dendrobii bud seals, and is placed in 4 DEG C of environment preserving.
Wherein, the pretreatment described in step (1) is the flower classified and bud to be cleaned, and removal of contamination and corruption
Rotten flower or bud, at room temperature dry to the anhydrous mark in flower surface.
Wherein, in step (2) during hot air drying, Herba Dendrobii flower lays 1～3 layer, gross thickness 1～3cm.
Wherein, step (2) stirs flower once every 1.0～1.5h in hot-air drying process.
Wherein, in step (3) during lyophilization, Herba Dendrobii bud lays 1～2 layer, gross thickness 0.5～1.0cm.
Using the Herba Dendrobii dry flower being dried to obtain by said method to make tea, dry flower is unfolded completely in tea, the reward heart is pleased
Mesh, tea is overall in golden yellow, yellowish or pale red, and fragrance is lasting, fragrant aroma；Compared with traditional drying mode products obtained therefrom
Tea color and luster is the most beautiful, and fragrance is the strongest persistently.
Compared with prior art, there is advantages that
What the Herba Dendrobii dry flower that the inventive method is dried to obtain was conventional with the most general Flos Camelliae Japonicae bakes and banks up with earth drying mode gained
Product compares color and luster, condition and quality all to be had and promotes in various degree, and dry flower form is intact, and bright color is bright-coloured, in yellowish green to golden
Yellow, has delicate fragrance；Further, the inventive method technological process is succinctly, easily operate, the shortest, energy consumption is low, substantially increases work
Make efficiency, reduce production cost.
