The invention discloses a cell wall breaking manufacture method of novel tea, comprising the following steps: preheating fresh tea; breaking wall for cells; primarily dewatering; secondarily dewatering; controlling moisture to 60-65%; and kneading. According to the method, the cell wall of the novel tea is broken, the effective ingredients, the fragment and verdant color of the tea can be better kept, and thus the manufacture method is suitable for processing all types of fresh tea.
Description
Technical field
The invention belongs to tealeaves preparation method technical field.
Background technology
[0002] no matter existing tealeaves preparation method completes or kneads, and mostly can not destroy the cell membrane tissue of tealeaves, makes made tea product in passes during brewing, be difficult to be dissolved in the millet paste fast because of inclusion receives the cell membrane retardance.
Publication number is that the Chinese patent of CN1602711A discloses a kind of method with the instant gas differential pressure processing tea leaf; This method adopts the instant gas pressure drop; Draw loose tealeaves institutional framework, make tealeaves organizer produce microfissure, and obtain breaking of histocyte even organelle.But there is following problem in this method: the one, and the tealeaves heating is inhomogeneous; Owing to be in high-pressure bottle, tealeaves to be heated and pressurize; And the transmission of the heat of air is poor; The high-pressure bottle wall of high temperature causes inhomogeneous to tealeaves heat time heating time and temperature in the same container easily, because can cause the sallow of the tealeaves that contacts; Two are to use high-pressure bottle both dangerous to the tealeaves heating, and the temperature that can make tealeaves be heated again is too high, and the tealeaves temperature will must cause a large amount of losses of effective content of tea above 165oC when heating boosts to 7 atmospheric pressure to high-pressure bottle; The 3rd, moment has and contains fragrant hot gas (heat energy) discharging of tea in a large number when opening high-pressure bottle, has both wasted heat energy, increases production cost, makes the fragrance of tealeaves lose in a large number again; The 4th, can not be used for processing to conditional tea products of high temperature such as Pu'er tea.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists; A kind of breaking-wall cell that both can make fresh tea leaf in its is provided; Can keep effective content of tea and fragrance and emerald green color and luster preferably again, and be applicable to the fresh tea leaf in its breaking-wall cell preparation method of all kind fresh tea leaf in its processing.
The object of the invention is realized through following technical scheme.
A kind of fresh tea leaf in its breaking-wall cell preparation method, method step is following:
(1) preheating: fresh tea passes was dropped in the eddy flow water tank that water temperature is 50oC ~ 95oC 2 ~ 4 minutes, and the weight ratio of fresh tea passes and water is 1:10 ~ 20, to the tealeaves thermally equivalent to 50oC ~ 95oC;
(2) breaking-wall cell: the breaking-wall cell jar is put in the tealeaves taking-up immediately; And be that the vacuum tank of 50 ~ 100 times of breaking-wall cell tank volume is connected with breaking-wall cell jar and volume; Control breaking-wall cell jar internal vacuum was reduced to below 0.06 atmospheric pressure in moment; Realize instantaneous controlled pressure drop, impel tealeaves ICW to vaporize and broken tealeaves cell membrane fast, and kept vacuum state 2 ~ 3 minutes;
(3) preliminary hydro-extraction: tealeaves is put into the dehydration equipment preliminary hydro-extraction from the taking-up of breaking-wall cell jar;
(4) second dehydration and control water content: will be positioned over wind net belt dewaterer through the tealeaves that preliminary hydro-extraction is handled and carry out processed once more; The leading portion guipure hot blast temperature of control wind net belt dewaterer is that 70oC ~ 120oC, back segment are cold wind, and processed to water content is 60% ~ 65%;
(5) knead processing: tealeaves is kneaded processing, impel further broken tealeaves cell membrane and La Song tealeaves cell tissue structure.
At preheating step, the water temperature in the eddy flow water tank is controlled at 80oC ~ 95oC, and fresh tea passes is completed and passivation tealeaves enzymatic activity.During to the conditional fresh tea passes of high temperature, the water temperature in the eddy flow water tank is controlled at 50oC ~ 80oC in preheating.
The present invention can install the aroma increasing equipment of extracting tea fragrance between tealeaves breaking-wall cell jar and vacuum tank when carrying out the breaking-wall cell processing.
The present invention has the following advantages at least: the one, and utilize the eddy flow hot water of 50oC ~ 95oC that tealeaves is heated, can get good to the even heats of fresh tea leaf in its.The 2nd, owing under 0.06 atmospheric pressure, just can make the water ebullition, gasification of 45oC, so the temperature that tealeaves is heated in the breaking-wall cell process is no more than 90oC, can reduce loss of active ingredients in the tealeaves; The 3rd, the characteristics according to the caffeine in the tealeaves leaches in the 85oC water temperature easily adopt optimum water temperature and soak time to control the content of caffeine of tea products, can produce the tealeaves that obtains low caffeine content, enrich tea products; The 4th, to handle with low pressure vessel, energy consumption is low, energy-saving safe; The 5th, can control the temperature of tealeaves effectively, be implemented between 50oC ~ 90oC and just can carry out broken wall treatment, and control tealeaves heated time the tealeaves cell, guarantee the quality of tea products.
Tealeaves instantaneous controlled pressure drop after the present invention will heat up utilizes the phase transformation of moisture content in the tealeaves cell promptly to vaporize and the internal stress that produces, comes fracturing cell walls and La Song tealeaves institutional framework, is a kind of innovative technology of Tea Processing industry.Because what adopt is the breaking-wall cell under the normal temperature state; The emerald green color and luster that can keep tealeaves; Effectively prevent tealeaves red stain, the black change and vexed Huang; Increase substantially the extraction rate of tea leaf quality and active ingredient, and can fully keep active ingredients such as receiving vitamin that high temperature destroys and amino acid in the tealeaves easily, to have established institutional framework basic in order to realize brewing tealeaves by cold water.
The specific embodiment
Further set forth content of the present invention below in conjunction with specific embodiment.
