Abstract
The invention discloses a processing method of green tea, belonging to the technical field of tea processing. The method comprises the steps of withering, rocking, fixation, rolling and baking and concretely comprises the steps of naturally withering picked tea leaves in the open air; then, withering by blowing the tea leaves by an air blower in a room for 2-3 hours; putting the withered tea leaves into a rocking machine, and carrying out rocking for three times; and after that, performing fixation on the tea leaves, rolling, baking, and packaging to obtain the green tea. The green tea has the characteristics of having green leaves with red edges, and being golden in liquor color, fragrant, mellow in taste as well as sweet and fresh in aftertaste after being drunk.
Description
Technical field
The invention belongs to Tea Processing technical field, be specifically related to a kind of processing method of blue or green tea.
Background technology
Blue or green tea is that I cross one of six large basic teas, belongs to semi-fermented tea, has both had the delicate fragrance of green tea, has again the mellow flavour of black tea, natural flowers and fruits fragrance and " the red limit of greenery " feature.Blue or green tea reaches kind more than 450 containing organic chemical composition, and inorganic mineral element reaches kind more than 40.Organic chemical composition and inorganic mineral element in blue or green tea contain many nutritional labelings and effective component.Organic chemical composition mainly contains: tea polyphenols, vegetable soda, protein, amino acid, vitamin, pectin element, organic acid, lipopolysaccharides, carbohydrate, enzyme, pigment etc., the aspects such as pharmacological action shows and reduces fat, defatting beauty.Fragrance, flavour and the health-care effect of blue or green tea uniqueness are day by day favored by people, and domestic and international market increases day by day to blue or green tea demand.
In the processing technology warp of blue or green tea, conventionally adopt rolling shaping, need to repeatedly carry out " bundle wraps, kneads, connects piece and dry ", shape to drying, the shaping time is long, labour intensity is large, and each link needs more people to understand operation repeatedly, and the broken dust tea of causing in rolling process is more.The processing technology that the patent No. " 201010181255.4 processing method of oolong tea " provides comprises the tune that withers, shakes green grass or young crops, fried green, shaping, dry, traditional rolling is replaced with kneading machine and the bent milli of two pots machine, shortened process time, reduced hand labor powerful, but shake green grass or young crops, fried green operation, affect the blue or green tea of finished product at kneading machine moulding, tea aroma, flavour etc., tea leaf quality, broken tea rate are caused to certain influence.
Summary of the invention
The mechanization production that the object of the invention is to realize blue or green tea processing, obtains high-quality blue or green tea.Provided technical scheme is provided is: a kind of processing method of blue or green tea, and comprise and wither, shake green grass or young crops, complete, knead, cure, concrete procedure of processing is as follows,
(1) wither and tealeaves is placed in to the outdoor 50-70 of spreading out minute of 28-35 ℃, the thick 2-3cm of stand leaf, again tealeaves is put into indoor spreading for cooling, controlled room temperature 25-28 ℃, treat that tealeaves is cooled to room temperature tea spreading is put in withering trough, the thick 3-5cm of stand leaf, with air blast, blow 2-3 hour, controlling air blast leaving air temp is 50-60 ℃, then spreads tealeaves out 2-3cm, be placed in the Indoor Natural 30-40 minute that withers, interval 15-20 minute turns over leaf;
(2) shake and blue or green tealeaves after withering is carried out to three times shake green grass or young crops, for the first time, tealeaves is put into vibration machine and shake 6-8 minute, tealeaves is placed in to indoor spreading for cooling, the thick 2-3cm of stand leaf, indoor temperature is controlled at 20-25 ℃, time 2-4 hour, for the second time tealeaves is put into vibration machine and want 4-5 minute, tealeaves is placed in to indoor spreading for cooling 2-3 hour, indoor temperature 22-25 ℃, for the third time tealeaves is put into vibration machine and want 2-3 minute, be placed in indoor spreading for cooling 1-2 hour, indoor temperature 25-28 ℃, the thick 2-3cm of stand leaf;
(3) complete above-mentioned tealeaves is placed in green-keeping machine and is completed, controlling green-keeping machine temperature is 250-300 ℃, green-keeping machine time 1-3 minute, and constantly in green-keeping machine, be filled with CO2, the amount adding is 600-800ppm, completes and finishes rear standing 10-20 minute;
(4) knead and above-mentioned tealeaves is put into kneading machine knead 5-8 minute, then use the vexed 10-15 minute of closed container heat, then tealeaves is spread out ventilative, then by tea rolling moulding;
(5) cure with curing on dryer, dryer temperature is 80-100 ℃, cures 5-8 minute, and spreading for cooling moisture regain is after 10-15 minute, tealeaves is placed in to temperature and is 60-80 ℃ and cures 10-20 minute, and spreading for cooling obtains finished product gross tea;
(6) packing is rejected above-mentioned dry tealeaves, pick up and practice not moulding tealeaves, treats that tealeaves is cooled to room temperature, is packaged to be finished product.
Described to wither in the outdoor time of spreading out be 50-60 minute, and temperature is controlled at 28-32 ℃, wither to tealeaves water content be 60-70%.
Described shake green grass or young crops for the first time vibration machine rotating speed be 15-20r/min, vibration machine rotating speed is 40-50 r/min for the second time, vibration machine rotating speed is 20-30 r/min for the third time.
The described control green-keeping machine temperature that completes is 250-280 ℃.Complete be by high temperature destroy and the fresh leaf of passivation in oxidase active, suppress the enzymatic oxidation of Tea Polyphenols in fresh leaf etc., evaporate fresh leaf part moisture, make tealeaves deliquescing, be convenient to knead shaping, distribute blue or green stink simultaneously, promote the formation of good fragrance.
Described stoving temperature is controlled at 85-95 ℃.
The substantive distinguishing features that the present invention is outstanding and significant progress are:
The present invention shake blue or green through jog-heavily shake-in shake; be that tealeaves cell is scentetd, be unlikely to be again piled into one, the operation that completes is destroyed tealeaves oxidase active through high temperature; add the CO2 activity of passivation tealeaves more fully; tealeaves integrality is protected, and the finished product tea that side of the present invention makes has the shaped particles that kneading tea has, and tealeaves is heavy real; broken tea rate is low; and process time is short, artificial intensity is little, has under equal conditions promoted fragrance and the flavour of blue or green tea.
The blue or green tea of the present invention has greenery red margination, soup coloured gold is yellow, fragrant high rich, drinks rear aftertaste sweet refreshing, and blue or green tea has the nature fragrance of a flower and pure and strong flavour.Drink the content that the blue or green tea of the present invention can effectively reduce metabolism of lipid and cholesterol in serum, often drink the blue or green tea of the present invention and can improve skin quality, have the effect of beautifying face and moistering lotion.
