Abstract

The invention provides a processing method of Yu tea. The processing method of the Yu tea comprises the following steps: (1), preparing raw materials: picking fresh Yu tea leaves from Yu tea trees, wherein the picked Yu tea leaves are tips with two or three leaves, performing spraying treatment on the Yu tea leaves while carrying out turning so as to ensure uniform spraying, transferring the Yu tea leaves into a cold storage so as to carry out cold-storage treatment for 0.2-0.5 hours, wherein the temperature of the cold storage is 5-10 DEG C, rapidly transferring the cold-storage treated Yu tea leaves into a constant-temperature darkroom at 90-100 DEG C in the presence of nitrogen protection atmosphere, carrying out treatment for 0.5-1 hour, and taking out the treated Yu tea leaves; (2), carrying out spreading; (3), carrying out fixing; (4), carrying out treatment by using a rub-withering machine; 5), carrying out carding; and 6), carrying out drying. The Yu tea prepared by the processing method is refreshing in aroma, as well as sweet and mellow in flavor.

Description

A kind of processing method of rain tea

Technical field

The invention belongs to Tea Processing technical field, and in particular to a kind of processing method of rain tea.

Background technology

Tea is the daily beverage in Chinese's life, treats tired with refreshing oneself, antipyretic to quench the thirst, and is helped digestion except greasy, bactericidal antiphlogistic, is prevented Dental caries permanent tooth, defatting beauty, and stomach diuresis, improving eyesight clears away heart-fire, and solution cigarette is sobered up, and is depressured grease removal, mitigates canceration, increases vessel wall elasticity, The various kinds effect such as atomproof radiation injury.

Modern biochemistry and medical research are proved, in the chemical composition of tealeaves, organic compound there are about 450 kinds with On, inorganic mineral nutrient is no less than 15 kinds, it can be seen that, tealeaves was both nutritious to human body, there is pharmacological action again, with People's is healthy closely bound up.

Rain tea has bud-leaf delicate, even neat because of it, and thin into tea bar rope is tight, color and luster is bud green, even neat straight and upright, shape such as pine needle； Millet paste is limpid bright, and fragrance is fresh clearly, flavour glycol, and leaf background color is green well received such as the characteristics of beautiful, but but without a kind of rule The rain production method for tea of model, realizes a large amount of productions of rain tea, therefore cannot meet the market demand.

The content of the invention

The present invention proposes a kind of processing method of rain tea, clear fresh, the flavour glycol of the rain tea perfume gas that the processing method is obtained.

The technical scheme is that what is be achieved in that：

A kind of processing method of rain tea, comprises the following steps：

1) raw material prepares：Fresh leaves of tea plant is plucked, two, three leaf blade tips are adopted, rain tealeaves is carried out into spraying treatment while being turned over To ensure that spraying is uniform, being then placed in freezer and processing 0.2～0.5h, temperature of ice house is -5 DEG C～-10 DEG C, is then shifted rapidly To the constant temperature darkroom disposal that temperature is 90 DEG C～100 DEG C, constant temperature darkroom is enclosed in nitrogen protective atmosphere, and process time is 0.5～1h, Then take out rain tealeaves；

2) spread：By step 1) the rain tealeaves that takes out carries out nature and spreads 8～10h, spreads thickness for 2～3cm；

3) complete：Using roller fixation machine, start to feed intake when temperature is 180～200 DEG C in cylinder, several times, hand is grabbed and completed for rolling Leaf spinosity feel, tack-free, hand pinches agglomerating, looses one's grip and dissipate；

4) repeatedly the cool green grass or young crops stand and shaking treating shakeouts the fresh leaf after completing in make conventional green grass or young crops air conditioning room, make each position in fresh leaf Moisture is leaked water uniformly again, is then placed in carrying out rolling and rotating manipulation in vibration machine, so repeatedly, fresh leaf green grass or young crops taste is moved back to the greatest extent, and leaf color is yellowish green, tea Blue or green soft, lubrication, make conventional green grass or young crops are completed, into manage bar；

5) manage bar：Using oscillatory type carding machine, 80～100 DEG C of bath temperature, 120～150g of water-removing leaves, middling speed reason are put into per groove Bar, low after temperature is first high, when tea orderliness is straight, the water content of tea bar reaches 20wt～30wt% machine spreadings for cooling at present；

6) it is dried：Using well-known tea baking machine, 100～120 DEG C of temperature, 1～2cm of leaf is spread out, turned over when drying, after temperature is first low Height, is dried to tealeaves hand and is twisted comminution, and machine spreading for cooling of raining obtains the tea to room temperature.

Further, step 1) if spray amount meet and speckle with above the blade face of tealeaves the globule.

Further, step 3) throw leaf amount 50～55kg/ hours.

Beneficial effects of the present invention：

1) based on traditional tea-manufacturing technology, with reference to rain tealeaves feature, quick temperature raising skill is combined by spray chilling technology The technological means such as art extend the rain Tea Processing time limit, can rapidly destroy the activity of enzyme in tealeaves, prevent tealeaves rubescent rotten, can Protection Tea Polyphenols.Need nitrogen protective atmosphere to enclose in 90 DEG C～100 DEG C of constant temperature darkroom disposal, be so conducive to protecting tea many Phenol, while increased scattering and disappearing for moisture in tealeaves, is easy to the program that subsequently completes.

2) tealeaves has bud-leaf delicate, even neat, and thin into tea bar rope is tight, color and luster is bud green, even neat straight and upright, shape such as pine needle；Tea Soup is limpid bright, and fragrance is fresh clearly, flavour glycol, and leaf background color is green such as the characteristics of beautiful.

Specific embodiment

Embodiment 1
