Abstract

The invention discloses a preparation method of oolong tea. The method comprises tea harvesting, standing of green leaves, drying of green leaves, cooling of green leaves, rocking of green leaves, frying of green leaves, trimming, primary baking, packaging, repeated baking and packaging, wherein in the packaging process, the tea leaves need to be packaged for six times by using a packaging machine; the leaf input amount is 100g every time; the packaging duration is 1-2 minutes every time; the tea leaves are scattered by using a scattering machine after the each packaging process is finished; and the scattering process is carried out together with the screening of red edges. By using the method, the formation of the tea leaves is controlled by using the packaging machine and the scattering machine, so that the efficiency is high and the formed tea leaves are attractive in appearance; the oolong tea prepared by using green tea raw materials is relatively low in cost; the tea leaves are baked and dried at a low temperature so as not to destroy vitamins in the tea leaves, and thus, the taste is increased while the damage to nutritional ingredients is prevented; and methods of segmental drying and spreading for cooling are used, so that the fragrance is increased, and the quality is improved.

Description

A kind of preparation method of oolong tea

Technical field

The present invention relates to a kind of preparation method's of tealeaves, particularly a kind of oolong tea preparation method.

Background technology

Oolong tea is the extraordinary well-known tea of China, also claims blue or green tea, is the class semi-fermented tea leaf between green tea and black tea.Oolong tea not only mouthfeel is unique, pleasant to the palate, also has good health-care efficacy, confirm through modern scientific research, oolong tea has except containing general tealeaves the benefit think of of refreshing oneself, eliminate outside the health cares such as fatigue, the diuresis of promoting the production of body fluid, analgesic heatstroke prevention, bactericidal antiphlogistic, detoxifcation diseases prevention, promoting digestion greasy, defatting beauty, also outstanding behaviours is at anti-cancer, reducing blood lipid, the anti-ageing special efficacy of waiting for a long time.

Oolong tea is when making, and its general employing that is shaped is manually kneaded or presses tea machine mode to carry out, and the tealeaves profile is guaranteed after kneading processing, but the process of kneading takes time and effort, and makes the Tea Production cycle longer; Adopt and press tea machine compacting tealeaves, although efficient is higher, the profile of finished tea is uneven, affects the finished product outward appearance; The local tea variety of plucking is generally blue or green tea, but the cultivation of less types and difficult of blue or green tea makes production cost raise; Frying and bake and bank up with earth after the tealeaves edge produce more red limit, make to mix more red limit powder in finished tea, can floating a large amount of red limit powder in soup juice when brewing, had a strong impact on mouthfeel and the outward appearance of tealeaves finished product; And traditional bakes and banks up with earth temperature generally at 80-300 ℃, and the too high temperature of baking and banking up with earth is easily destroyed the materials such as vitamin that tealeaves contains, and has reduced the nutrition of tealeaves.

Summary of the invention

The object of the invention is to: a kind of preparation method of oolong tea is provided, and, appearance poor high with the cost that exists in the preparation method that solves traditional oolong tea, production cycle are long, tealeaves mixes that red limit is many, the easy problem of loss of nutritional labeling.

Technical scheme of the present invention:

A kind of preparation method of oolong tea, the method comprise the steps: to adopt green grass or young crops, stand blue or green, shine green grass or young crops, cool green grass or young crops, shake green grass or young crops, fried green, trimming, just baking, packing, multiple baking and encapsulate, wherein: described packing process adopts baling press to play bag six times, each leaf amount 100kg that throws, each packaging time length 1-2min, break up with beater after each packing finishes, and the process of breaing up is followed screening out of red limit.

The described local tea variety of plucking in green grass or young crops of adopting is the green tea that produces in spring, autumn.

Described green tea kind is Fujian Da Bai tea.

Described just baking temperature is 55-70 ℃, and the time is 10-30min.

The described temperature of drying by the fire again is 65-85 ℃, and the time is 5-10min.

Described just baking temperature is 60 ℃, and the time is 20min.

The described temperature of drying by the fire again is 75 ℃, and the time is 8min.

Compared with prior art, the preparation method of oolong tea provided by the invention has the following advantages: 1) adopt baling press and beater to control the shaping of tealeaves, its not only efficient high and also be shaped after the tealeaves good looking appearance;

2) adopt green tea materials to make oolong tea, cost is lower;

3) adopt low temperature to bake and bank up with earth drying, can not destroy the vitamin in tealeaves, increased mouthfeel in the time of the destruction that prevents nutritional labeling;

4) adopt the method for stage drying and spreading for cooling, be beneficial to lifting fragrance, improve quality.
