Description
Technical field
The present invention relates to method and Zymolysis Equipment thereof prepared by a kind of black tea, specifically a kind of black tea withers fermentation all-in-one and black tea preparation method.
Background technology
The utilization of Folium Camelliae sinensis has had a long history, and tea is one of our people's daily necessities.Traditional black tea, focuses on the endoplasm of product, particularly requires the red soup of black tea red autumnal leaves, i.e. requires have sufficiently fermentation to produce enough brown stains with leaf color.The conventional machining process of black tea is for withering → knead → fermenting → dry.Black tea is owing to by fermentation, polyphenols therein is fully oxidized and degrades, and forms more theaflavin and thearubigins.At present, black tea manufacturing process deblocks through withering, ferment, kneading moulding, dry, cool down finished product classification packaging, every one procedure all equipments or machinery with special processing black tea complete, and the material transportation of per pass inter process to expend a great deal of time and manually.Particularly in tea leaf withering and fermentation, owing to the time waited is long, production and processing inefficient.And the equipment used in traditional sweat cannot be carried out stirring and turns over even so that the quality of black tea is affected by certain.
Summary of the invention
The purpose of the present invention be exactly for solve prior art exist problem, and devise a kind of black tea wither fermentation all-in-one and use this device produce black tea method, be effectively improved the speed that black tea withers, ferments, and the quality of black tea.
The technical scheme is that a kind of black tea withers fermentation all-in-one, including being provided with the airtight housing of folding hermatic door, be provided with runing rest in described housing, runing rest is the support being provided with multilayer parallel aspect, and every layer of support is provided with the large bamboo or wicker basket holding Folium Camelliae sinensis；Described runing rest is connected with top and the bottom of housing cavity by the rotation central axis at upper and lower two ends, and by being arranged on the motor-driven rotation below housing；The side of described housing cavity is provided with warm-air pipe, and the tube wall of warm-air pipe is provided with multiple gas outlet, is provided with blower fan and electric heater unit in warm-air pipe；The lower section of described housing is provided with the atomizing device for humidification, and atomising device is communicated in inner chamber by humidifier tube.
The technical characteristic of the present invention also has: the outside of described housing is provided with control chamber, is provided with automatic control system and electrically connects with motor, blower fan, electric heater unit and atomising device in control chamber, it is achieved switch timing controlled.
Described runing rest includes the support post being arranged on excircle, forms multiple structure by some connecting rods of horizontally set, is provided with rotation central axis at the center, two ends up and down of runing rest and is connected with housing.
In order to be able to realize automatic turning Folium Camelliae sinensis in sweat, being provided with the electric magnet of high intensity in the housing of described intracavity bottom, the activity that is provided with in described large bamboo or wicker basket is placed with the stirring sheet that permeability magnetic material is made.
Black tea be withered in order to breathe freely and ferment evenly, described large bamboo or wicker basket is disc, the bottom Reticular breathable bottom surface of large bamboo or wicker basket.
In order to promote fermentation, improving the mouthfeel of black tea, the intracavity sidewall of described housing is provided with red globe lamp.
Excellent quenched in order to enable Folium Camelliae sinensis is carried out, described red globe lamp be the light sent be the LED of 630～640nm wavelength HONGGUANG, fragrance level and persistence can be improved.
In order to be able to promote that fermentation of black tea keeps equilibrium temperature, each sidewall of described housing is equipped with heat-insulation layer.
Present invention also offers a kind of black tea preparation method using above-mentioned all-in-one, preparation method includes successively withering, kneads, ferments, dries, described in step of withering be: fresh leaf is withered by a., and the fresh tea leaf after plucking is laid in large bamboo or wicker basket, and thickness is 5-6cm；B. large bamboo or wicker basket is sent in all-in-one, open the hot blast that temperature is 25 DEG C-40 DEG C, open red globe lamp simultaneously and be irradiated quenched, take out after keeping 3-5 hour；After taking-up, Folium Camelliae sinensis is put into rolling and modeling in kneading machine.
Owing to fermentation of black tea early stage uses relatively-high temperature, middle and late stage to use the fermentation process of relative low temperature, the accumulation of the formation of the most coloured oxidation product thearubigins, improve the quality that black tea is bright.Fermentation temperature can pass through Artificial Control, the timely warming and humidifying when temperature is relatively low, and realizes temperature adjusting by leaf-spreading thickness, in good time turning, in case too high or too low for temperature.Described fermentation step is: the Folium Camelliae sinensis after moulding is placed in large bamboo or wicker basket by a., and Folium Camelliae sinensis tiling thickness is 7-10cm；B. sending in all-in-one by large bamboo or wicker basket, open the hot blast that temperature is 25 DEG C-30 DEG C, and open atomising device simultaneously, keeping all-in-one humidity is 80-90%.Keep 4-5 hour, and turn down temperature 2-3 degree per hour；During fermentation stir Folium Camelliae sinensis 2-3 time；After having fermented, taking-up Folium Camelliae sinensis is put in dehydrator and is dried.
In order to be able to obtain more preferable black tea mouthfeel, increase the activity of useful mushroom in sweat, described sweat is opened in all-in-one red globe lamp and carries out auxiliary irradiation.
Beneficial effects of the present invention can be drawn by such scheme: owing to the withering equipment and the Zymolysis Equipment that use in black tea manufacturing process being united two into one, i.e. saves equipment investment, and improves production efficiency.The effect in use withered by being passed through hot blast fully to improve；Also there is humidification function, it is achieved the excellent yeasting of constant temperature and humidity during fermentation.And may utilize the strong magnetic force of electric magnet during the fermentation, the stable string that attracted each other by the stirring sheet in each layer large bamboo or wicker basket is associated in large bamboo or wicker basket.Owing to large bamboo or wicker basket is constantly in rotation status, so stirring sheet slides on the bottom surface of large bamboo or wicker basket, Folium Camelliae sinensis in realizing large bamboo or wicker basket carries out stirring stirring by stirring sheet so that tea leaf fermentation is more uniformly fully.Present invention also offers a kind of black tea preparation method using this equipment, prepare difference with conventional black to be, when using this equipment to be prepared black tea, the process wither, fermented is different, the control realization of each ambient parameter raising production efficiency, fermentation of withering black tea is more uniform, can obtain mouthfeel more preferably black tea.By equipment and the black tea preparation method of the present invention, solve the defect that in existing black tea equipment, the equipment of each step can not be multiplex, and improve quality and the production efficiency of black tea.
As can be seen here, the present invention compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
