Abstract

The invention discloses a clean tea production process. The production process comprises the following steps: rotationally rinsing, spray washing, rotationally whirling, drying with cold air, spreading out, grading, deenzyming, primarily winnowing, spreading for drying in the air, primarily rolling, frying at constant temperature in the way of electric heating, spreading out, rolling, winnowing, blending, piling, completely baking, preparing into finish products, inspecting and warehousing. The cleaning process and primarily winnowing processes are added, and the external impurities can be removed; electric-heating constant-temperature frying is adopted to replace the traditional primarily baking process, thus the tea can be heated uniformly and can be prevented from being polluted by other heating materials; dried-up tea dust or carbonized tea dust can not be generated; the tea is held with containers when transferred among different processes; dust and residues are removed in each process in production so that the tea can not be polluted and can not generate pollution impurities in the processing process; thus the purpose of clean tea production is achieved; and the tea does not need to be washed when brewed, thus greatly improving the utilization of the nutritive substances of the tea.

Description

A kind of clean tea production process

Technical field

The invention belongs to a kind of production technology of tealeaves, especially a kind of tealeaves clean production technology.

Technical background

Tealeaves is the necessity that we live, and the first program that we have tea at ordinary times is " washing tea ", and " tea of waking up " " gentle bubble " " profit tea " etc. also is in some place, and purpose is for the impurity that is attached on tealeaves is washed off.But in order to show the quality of tealeaves, add man-hour with tea the part nutriment in bright leaf excessive and be exposed to tea bar surface, after tea-drying, the nutriments such as excessive protein, amino acid, Tea Polyphenols out are attached to tea bar surface with crystalline state, these materials belong to water-soluble substances, in case contact with hot water, just can be dissolved in a large number water within several second.Although washed impurity off so wash tea, also washed a large number of nutrients off.In order to address this problem, begin now to have occurred some clean tea production technologies, make every effort in the production phase, tealeaves be kept clean as " Tea Industry circular .2010.32 (2): 87-89 " simple analysis clean tea production technology " ", in order to need not wash tea when brewing, keep the genuineness of tealeaves.But these technology are to emphasize to keep the overall process clean hygiene from management view, avoid pollution sources and reach the purpose that cleans production, these methods can play certain effect, but do not reach the real purpose that cleans, particularly do not note taking precautions against the pollution impurity that tealeaves self produces in process.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of clean tea production process, so that a kind of clean finished tea that cleans to be provided, needn't wash tea when brewing.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is a kind of clean tea production process, the rinsing that the steps include: to overturn, spray irrigation, rotation drying, cold wind dry up, spread, classification, complete, preliminary selection by winnowing, airing, tentatively knead, electric heating constant temperature is flatly fried, spread, knead, selection by winnowing, assorted, pass heap, sufficient baking, finished product, check, warehouse-in; It is characterized in that having increased that upset rinsing, spray irrigation, rotation drying, cold wind dry up, preliminary selection by winnowing operation on existing production technology basis, and change existing just baking operation into the flat stir-fry of electric heating constant temperature operation.The rinsing process that wherein overturns adopts the pure water of 8-10 ℃, and rinsing time is 2-4 minute; The spray irrigation operation adopts the pure water of 8-10 ℃, and spray time is 1-2 minute; Cold wind dries up and adopts the cold air of 8-10 ℃, and the time of drying up is 2-4 minute; The blast of preliminary selection by winnowing is 430-480Pa, and air quantity is 6500-7500m ³/ h; The flat temperature of frying of electric heating constant temperature is 400-420 ℃, and the flat stir-fry time is 5-8 minute; Adopt the utensils such as bamboo plaque, bamboo mat between every procedure during mobile tealeaves, guarantee that tealeaves does not spread on ground in any link of producing; Want dust out and foreign material before all in flow process, every procedure begins, will in time remove residual tealeaves after completing, keep the equipment cleaning health.

The invention has the beneficial effects as follows has increased by one group of cleaning process, introduced contaminants can be removed, and can guarantee that with cold rinse the nutriment in tealeaves can not ooze out; Increased together preliminary selection by winnowing operation, the impurity dust of leaving over after completing can have been removed; Adopt the flat operation of frying of electric heating constant temperature to replace existing just baking operation, not polluted by other heating material when tealeaves is heated evenly, withered tea dust or carbonization tea dust can not occur; When shifting, tealeaves uses the utensil splendid attire between every procedure, every procedure dust out and residually guarantee that tealeaves can not be subject to polluting yet can ownly not produce pollution impurity in process during production, reached the purpose that clean tea is produced, need not wash tea when brewing, greatly improve the utilization rate of the nutriment of tealeaves.

The specific embodiment

Be elaborated as an example of production 100kg green tea example.

Pluck the bright leaf of 100kg, drop into service sink, adopting the common pure water of 10 ℃ to overturn cleaned 3 minutes, follow thin being layered on the screen cloth conveyer belt with same water spray irrigation 1 minute, then dropping into the roller machine rotation dries, fall into again on the screen cloth conveyer belt and dry up with cold wind, the temperature of cold wind is 10 ℃, the time of drying up is 3 minutes, then through bright leaf stackings, bright leaf classification, complete, preliminary selection by winnowing, airing, knead, electric heating constant temperature is flatly fried, spread, knead, selection by winnowing, assorted, pass heap, sufficient baking, finished product, check, put in storage at last; Wherein the blast of preliminary selection by winnowing is 430Pa, and air quantity is 6500m ³/ h; The flat temperature of frying of electric heating constant temperature is 400 ℃, and the flat stir-fry time is 5 minutes; Between every procedure, mobile tealeaves adopts bamboo plaque, bamboo mat simultaneously; All in flow process, every procedure begins front dust out and foreign material, and the residual tealeaves of timely removing after completing keeps the equipment cleaning health.
