Description
Technical field
The present invention relates to jasmine tea preparing technical field, and in particular to a kind of preparation method of Jasmine flower tea.
Background technology
The jasmine tea that Jasmine is made, is a kind of Chinese unique teas.Song Dynasty leaf court of a feudal ruler Gui is chanted in the poem of jasmine tea,
There are so two：" dew China wash-off the whole body is white, and heavy water smoking is fragrant into bone is changed." it process it is complicated, be by tea and spend two kinds of originals
Material is processed, and is told fragrant, tea base by fresh flower and is enfleuraged, one tells a suction, is allowed to the elegant fragrance of a flower of existing fragrance, there is mellow sweet and refreshing again
Tea flavour, tea draws the fragrance of a flower, brings out the best in each other, and does not have graceful bearing.Because jasmine tea has the strong tasty and refreshing natural tea flavour of green tea, satisfy again
Contain the fresh fragrance of Jasmine.Often drink jasmine tea, clear liver and improve vision, promote the production of body fluid to quench thirst, dysentery is controlled in eliminating the phlegm, defaecation Li Shui, wind-dispelling
The effect of inducing diaphoresis, hypotensive, cardiac stimulant, anti-aging.In the technical process of production jasmine tea, mainly include fresh flower maintenance, basement
System, logical spend, rocket, baking and the technical process such as metering packing.Fresh flower maintenance is mainly used as scenting jasmine tea from jasmine fresh flower
Spices；The Jasmine conserved is evenly mixed in tealeaves by scenting mainly according to Jasmine, the ratio of tealeaves；Logical flower
Mainly to Jasmine, the control of tealeaves mixed process, the fragrance of Jasmine is immersed into tealeaves；Rocket and mainly use sieve flower machine will
Jasmine and tealeaves are separated；Tealeaves after separation is baked and metering packing again, so as to complete the production of jasmine tea
Make.Current Jasmine is mixed and made into jasmine tea with the material such as green tea mostly, and preparation process is complicated, and time-consuming, and is preparing
During in Jasmine nutrient loss it is serious；Number of patent application discloses one for 201410128168.0 patent text
Preparation method of eucommia bark jasmine tea and products thereof is planted, by complicated scenting, short time consumption is long, process is complicated, wherein bakee
Temperature is too high, causes the active ingredient in jasmine tea to decompose and be lost in；Number of patent application is 201410216554.5 patent text
Disclose a kind of jasmine tea process for cleanly preparing, mainly include fresh flower maintenance, scenting, lead to spend, rocket, baking, vibrating transportation
And packaging, solution be jasmine tea clean manufacturing the problem of, but the same process complicated and time consumption time is long.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, provide a kind of preparation method of Jasmine flower tea, the present invention
Preparation method be that green tea is made after concentrate to mix with Jasmine, in the absence of oxygen, green tea concentrated liquid penetrate into jasmine
Hua Zhong so that the delicate fragrance that jasmine tea retains Jasmine and green tea is made in the later stage, and millet paste is clear, reduces compared with the prior art
Fresh flower maintenance, scenting, logical flower, the complex process rocketed, dry Jasmine, than straight by way of dry ice is repeatedly freezed and vacuumized
Connect sublimation drying significantly to shorten, while reducing the nutrient loss of Jasmine.
The technical scheme that the present invention is provided is：
A kind of preparation method of Jasmine flower tea, comprises the following steps：
Step 1: after Jasmine is cleaned up, being spread out on the net in shelf and drying surface moisture content, Jasmine is put into roller
