Abstract
The present invention relates to particularly a kind of production technology of instant tea of a kind of Tea Processing, it comprises infusion of tea, and tea juice filters, vacuum concentrates for the first time, for the first time freezing dish branch, cold vacuum concentrates for the second time, processing steps such as freezing dish branch, spray-drying for the second time, the instant tea goods.That the instant tea of gained of the present invention has is instant, cold cut, limpid, high-quality slender joss stick four big advantages, in 4 ℃ water, can dissolve, and limpid bright no any precipitation of the aqueous solution and muddiness, though and extract through complicated technology, but still keep the delicate fragrance local flavor of former tealeaves.
Description
The present invention relates to a kind of processing extracting method of tealeaves, specifically, is a kind of production technology of instant tea.
Instant tea is started to walk soon in the research of China, instant tea has appearred in markets such as the U.S., Japan, their processing method generally takes tealeaves → tea juice extraction → filtration back to concentrate and form, gained instant tea solubility is bad, impurity is many, presentation quality after influence brews, Japan is that the tealeaves leaching process is divided into low temperature and two steps of heating openly speciallyying permit the disclosed technical characterstic of the clear 61-15651 of communique (A), tealeaves is different with the ratio of water in each step, formality is numerous and diverse, and the instant tea of making only is suitable for dissolving in 80 ℃ the water to be drunk.The manufacture method that the Chinese patent communique disclosed a kind of instant tea on July 19th, 1989, application number: 88105853.X, it adopts 5-50 ℃ water repeatedly to leach, instantaneous sterilizing, vacuum decompression concentrate, frozen drying or vacuum drying or spray-drying are produced instant tea, its shortcoming is, the instant tea of its gained is still impure, and when dissolving water temperature need be higher than 15 ℃, make troubles to drinking still summer.
The object of the present invention is to provide a kind of can the dissolving in 4-100 ℃ water, aqueous solution clear does not have the production technology of the instant tea of any impurity.
For achieving the above object, the present invention adopts following technical scheme: infusion of tea stripping tea juice, and tea juice filters to get filtrate, and it is characterized in that:
A. filtrate below 50 ℃, is concentrated into 8-12B é more than 0.1MPa vacuum, time concentrate of winning;
B. concentrate was refrigerated to 4-10 ℃ of maintenance after 24-48 hour for the first time, carried out centrifugal dish and divided impurity elimination, got supernatant;
C.b step supernatant below 50 ℃, is concentrated into 16-23B é more than 0.1MPa vacuum, get concentrate for the second time;
D. concentrate was refrigerated to 4-10 ℃ of maintenance after 24-48 hour for the second time, carried out centrifugal dish once more and divided impurity elimination, got supernatant;
E.d step supernatant spray-drying promptly gets this product.
The freezing dish branch of above-mentioned secondary is to guarantee instant, the cold-water solution of this product, and limpid nothing is assorted, high-quality slender joss stick key technology; The spray-drying inlet temperature was 150-250 ℃ during above-mentioned e went on foot, and outlet temperature is 60-150 ℃.
The present invention compared with prior art has following advantage:
That products obtained therefrom has is instant, cold cut, limpid, high-quality slender joss stick four big advantages; This product 0.5 gram dissolves immediately with 100ml hot water, cold water went out solubilized at 2 minutes, stir i.e. dissolving rapidly in 2 minutes in 4 ℃ of water, limpid bright no any precipitation of this instant tea aqueous solution and muddiness, though and extract, but still keep the delicate fragrance local flavor of former tealeaves through complicated technology.
The invention will be further described below in conjunction with embodiment:
Embodiment 1, tealeaves 40Kg, with 40Kg water moistening after, respectively soak about 30 minutes for twice with 400Kg90 ℃ moisture, merge soak twice, plate-frame filtering, filtrate is more than 0.1MPa vacuum, be concentrated into 10B é under 45 ℃ of conditions, time concentrate of winning, with its be refrigerated to 4 ℃ and keep 30 hours after, on the dish extension set, separate, supernatant more than 0.1MPa vacuum, be concentrated into 20B é under 45 ℃ of conditions after, be refrigerated to 4 ℃ and kept 30 hours once more, on the dish extension set, carry out the centrifugation second time then, get supernatant 200 ℃ of inlet temperatures, 100 ℃ of following spray-dryings of outlet temperature make the instant tea about 4Kg.
Embodiment 2, tealeaves 40Kg, getting tea juice after soaking filters, get filtrate, filtrate is more than 0.1MPa vacuum, be concentrated into 8B é under 38 ℃ of conditions, time concentrate of winning, with its be refrigerated to 10 ℃ and keep 48 hours after, on the dish extension set, separate, supernatant more than 0.1MPa vacuum, be concentrated into 16B é under 38 ℃ of conditions after, be refrigerated to 10 ℃ and kept 48 hours once more, on the dish extension set, carry out the centrifugation second time then, get supernatant 150 ℃ of inlet temperatures, 60 ℃ of following spray-dryings of outlet temperature make the instant tea about 4.1Kg.
Claims (2)
