Abstract
The invention discloses a further processing process of caulis dendrobii flower tea and relates to the field of tea manufacturing methods. After pretreatment water content of caulis dendrobii flowers ranges from 60% to 70%, appropriateness in the pretreatment process of the caulis dendrobii flowers can be judged so as to have various indicators in the pretreatment process of the caulis dendrobii flowers controlled, and pressure control by a setting machine is favorable for controlling over shapes of the flower tea so as to improve quality of the flower tea; after setting, the caulis dendrobii flowers are socked in a vitamin C solution for 20-30 minutes, so that the flower tea is enabled to be high in nutritional value, freeze drying in the next step is benefited. By control over the freeze drying process and conditions, the caulis dendrobii flowers can be subjected to freezing processing before dehydration, so that the caulis dendrobii flowers can be solidified to form a stable skeleton structure, moisture in materials is enabled to be decreased to the level that biological or chemical reaction of the moisture cannot be sustained in a long time, good drying effect is achieved, and the caulis dendrobii flowers are broad in market prospect.
Description
Technical field
The invention belongs to Tea manufacture field, more particularly, the present invention relates to a kind of deep process of dendrobium nobile flower tea.
Background technology
The stem of noble dendrobium (has another name called lofty or bottomless palpus, bracketplant, Lin Lan, golden hairpin China etc.Stem is upright, and meat shape is plump, and slightly flat is cylindrical, long 10-60 centimetre, slightly reaches 1.3 centimetres.Medicinal plant, property slightly sweet flavor is micro-salty, cold, returns stomach, kidney, lung channel.Reinforcing stomach reg fluid is nourishing Yin and clearing heat.Hinder body fluid deficiency for the moon, dry polydipsia, food is few retches, and abnormal heat after being ill, order is secretly failed to understand.Stem of noble dendrobium flower appearance is graceful, and exquisite lovely, pattern is bright-coloured, fragrant odour, is called one of " four view and admire greatly ocean flower ".The main component of stem of noble dendrobium flower is volatile oil, and having effect that clearing heat and promoting fluid, enriching yin solution are strongly fragrant and hypotensive, is the good merchantable brand of Summertime.
Summary of the invention
It is lastingly pure and fresh that problem to be solved by this invention is to provide a kind of tealeaves endoplasm fragrance, the deep process of soup look light green bright dendrobium nobile flower tea.
To achieve these goals, the technical scheme that the present invention takes is:
A deep process for dendrobium nobile flower tea, comprises the steps:
(1) pretreatment
The stem of noble dendrobium flower plucked is rejected impurity, picks up with after distilled water cleaning, immersion 1-3min, airing 1-2h;
(2) complete
Completed by pretreated stem of noble dendrobium flower green-keeping machine, injected volume is 200-300g, and the temperature completed is 290-310 DEG C;
(3) frying
Stir-fry the colored frying pan of putting into of the stem of noble dendrobium after completing to flower in granule shape, the time stir-fried is 4-6min, and temperature is 300-320 DEG C;
(4) formalize
Then transfer in boarding machine and formalize, the temperature of setting is 310-330 DEG C;
(5) dry
Stem of noble dendrobium flower after setting is carried out freeze drying process;
(6) classification
Dried jasmine tea is carried out classification by color and luster and form.
Preferably, after pretreatment described in described step (1), the water content of stem of noble dendrobium flower is 60-70%.
Preferably, in described step (4), the pressure of forming machine is 0.08-0.15MPa.
Preferably, by stem of noble dendrobium flower 0.5-0.7g/L vitamin c solution immersion 20-30min after described step (4) setting, pick up, be laid on pallet after spreading for cooling, thickness is 0.5-0.7cm.
Preferably, it is dry that the process of freeze drying process in described step (5) is precooling, freeze-drying is conciliate in freeze drying.
Preferably, the temperature of described precooling is-20 DEG C--18 DEG C, and the time is 6-8h, and cryodesiccated pressure is 0.1-0.3MPa, and the time is 10-12h, and temperature is-60--50 DEG C, dry temperature of thawing is 10-12 DEG C, and the time is 3-4h.
Beneficial effect: the deep process that the invention provides a kind of dendrobium nobile flower tea, after pretreatment, the water content of stem of noble dendrobium flower is 60-70%, can judge that the stem of noble dendrobium is spent the appropriateness in preprocessing process thus controls the control of indices in dendrobium nobile flower tea machine process, the Stress control of forming machine is conducive to the shape controlling of jasmine tea, thus improve the quality of jasmine tea, after setting, stem of noble dendrobium flower vitamin c solution is soaked 20-30min, being of high nutritive value of jasmine tea can be made to also help next step and cryodesiccatedly to carry out, the process of freeze drying process and the control of condition, the stem of noble dendrobium is spent can first through freezing process before dehydration, thus solidify the stable skeleton structure of formation, moisture in material is reduced to and makes it cannot maintain the level of biology or chemical reaction in for a long time, thus obtain good drying effect.There are wide market prospects.
