Abstract
The invention discloses an automatic continuous manufacturing process for green tea. The process comprises the procedures of storing fresh leaves, deactivating, using a conveying belt (blast type), regaining moisture, using the conveying belt, kneading and twisting, using the conveying belt (vibrating) medium block, using the conveying belt (cooling), primarily drying, using the conveying belt (air-conditioning cooling), using a stepped continuous carding machine, using gross fire, spreading and secondarily drying to extract fragrance. The green tea manufactured by the method has the characteristics of green and oily color, compact and graceful appearance, and rich fragrance and mellow taste. By the method, mechanized processing and pollution-free production of the green tea are realized; labor intensity is greatly reduced; working efficiency is improved; production cost is reduced; and quality of products is improved.
Description
Technical field
The present invention relates to the producing green tea field, be specifically related to the continuous manufacture craft of a kind of green tea automatization.
Background technology
Green tea is unleavened, and Chinese output is maximum, drinks the most a kind of tea. its feature is that the clear leaf of soup is green.Tea the Englishman is: the liquid of health, the drink of soul.Be described as " state's drink " in China.The big quantity research of modern science confirms; Tealeaves contains and the closely-related biochemical composition of health really; Tealeaves not only has to refresh oneself and clears away heart-fire, clearing away summerheat, eliminates indigestion and phlegm, goes greasy fat-reducing, the relieving restlessness that clears away heart-fire, detoxifcation to sober up, promote the production of body fluid to quench thirst, fall that fire makes eye bright, only pharmacological action such as dysentery dehumidifying; Also,, certain pharmacological effect is arranged like diseases such as Radiation sickness, cardiovascular and cerebrovascular diseases, cancers to modern disease.The Main Ingredients and Appearance that tealeaves has pharmacological action is Tea Polyphenols, caffeine, lipopolysaccharides, theanine etc.
The processing technology of green tea is varied, but great majority adopt artisan craftsmanship to process, and is so both unhygienic, and operating efficiency is low, can not satisfy the fast-developing needs of society.
Summary of the invention
In order to overcome the deficiency of prior art, the invention provides the continuous manufacture craft of a kind of green tea automatization.The green tea that the inventive method is made has look green oil profit, and shape is tightly beautiful, the characteristics of thick aroma and good taste.Realized that Green Tea Processing mechanization, production clean, greatly reduced labour intensity, improved operating efficiency, reduced production cost, improved the quality of product.
The technical scheme that adopts for the present invention of realization above-mentioned purpose is following:
The continuous manufacture craft of a kind of green tea automatization is characterized in that may further comprise the steps:

(2) complete: will store the blue or green leafiness that finishes and put in the tealeaves roller fixation machine, the processing that completes is made as 280-320 ℃ with bowl temperature earlier, and the input and output material time is adjusted into 85-95s, treats can throw leaf when the charging aperture temperature rises to 110-120 ℃;
(3) tide is put back at the stand: the end that completes, water-removing leaves is transported to damping machine by conveyer belt, and to spread out and put back to the tide processing, the stand time of putting is controlled at 45-55min;
(4) knead: the bright leaf after put at the stand is transported to the combined type tea twisting machine by conveyer belt and kneads, and the kneading machine rotating speed is thrown leaf from bung 2-4cm at 45-50 rev/mins; In the process of kneading, according to gently-heavy-light principle, be generally light pressure 4-5 minute; Weight 9-11 minute again, gently to press again 4-5 minute, the degree rolled twig rate of kneading is 80-90%; Cell-damaging rate reaches 50-60%, has held outside the tea juice, and the sticking hand of loosing one's grip overflows; Leaf group does not loose and is standard, and the tealeaves after kneading is with the machine of deblocking processing;
(5) baking just: the tealeaves after kneading, deblocking adopts mesh belt dryer to carry out baking just; The hot blast temperature of dryer is set 120-130 ℃, and turnover leaf time set is 10-15 minute, treats that temperature shows when reaching requirement; The unlatching conveyer belt begins to throw leaf and carries out baking just; When just baking finishes, requirement, the tealeaves moisture content is 50-60%;
(6) ladder reason bar: the tealeaves that baking just finishes is transported to the first slot type carding machine by conveyer belt, and the air outlet that top one side of conveyer belt is provided with the air conditioner air conditioner is towards conveyer belt; Reach quick cooling purpose, in the groove of carding machine, add the iron wire of No. 10 cleanings, do auxiliary reason bar while carrying; Impel the tealeaves rolled twig rate, reach straight and upright complete, described iron wire length is not more than the length of reason bar groove; The temperature of carding machine is made as 300-350 ℃, when treating that temperature reaches requirement, opens conveyer belt and throws leaf automatically; Tealeaves is managed bar after 3-5 minute at first carding machine; Get in second carding machine, carried out secondary reason bar 3-5 minute, the tealeaves moisture content is 40-50% behind the reason bar;
(7) gross fire: the tealeaves behind the secondary reason bar carries out gross fire with the net belt type dryer once more and cures, and stoving temperature is 110-115 ℃, and the turnover leaf time is 9-10 minute, and oven dry tealeaves moisture content is at 13-17%;
(8) spreading for cooling: the tealeaves behind the gross fire should in time spread out to be put, and thickness 8-1 2cm is put at the stand, and the time was put more than 10 hours in the stand;
(9) multiple baking: the gross fire tealeaves after the above-mentioned spreading for cooling cures with mesh belt dryer again, and stoving temperature is 85-90 ℃, and the turnover leaf time is 6-7 minutes, dries the tealeaves moisture content at last and is not more than 6%, gets final product.
Beneficial effect of the present invention:
Green Tea Processing technology of the present invention combines plurality of devices, forms cover production-lines; Realized the purpose that the cleaning serialization is produced, had the output height, cost is low; The characteristics that production efficiency is high; The green tea that the inventive method is made has look green oil profit, and shape is tightly beautiful, the characteristics of thick aroma and good taste.Realized that Green Tea Processing mechanization, production clean, greatly reduced labour intensity, improved operating efficiency, reduced production cost, improved the quality of product.Concrete characteristics are following:
