Abstract
The invention discloses an alkali-reducing cover device of tea, wherein the device is used with a tea drying bucket; after caffeine in the tea is sublimated by an inner and outer double-layer structure, the caffeine does not condense and fall, and is discharged from the drying bucket with hot air. The alkali-reducing cover device is designed to quickly assemble and disassemble with the drying bucket. With the adoption of the device, caffeine content in the tea can be effectively reduced and the tea quality is improved.
Description
Technical field
The present invention relates to a kind of tealeaves and fall alkali closure assembly and using method, belong to the Tea Processing technical field.
Background technology
Low caffeine tea is a kind of novel teas that the specific crowd of caffeine sensitivity such as neurastheniac, pregnant woman, old man, children etc. are drunk of being suitable for.Use the apparatus for hot processing tea tea-processing, after the caffeine in the tealeaves runs into the high temperature distillation and enters the above air of baking bucket, because the reduction of external air temperature can be fallen back in the tealeaves again, so that caffeine content is always higher in the tealeaves in regelation.And existing reduction Tea Caffeine technique comprises hot water extraction, organic solvent extractionprocess, overcritical C0
2Extraction method, chromatographic absorption method etc., owing to can not guarantee the security of product, perhaps technique is too complicated, is not suitable for normal Tea Processing enterprise and uses.
Summary of the invention
The technical issues that need to address of the present invention are: overcome the deficiency of background technology, a kind of apparatus and method that reduce Tea Caffeine are provided, these apparatus and method can guarantee the security of tea products, have again easily operability, can be too not complicated.
The technical solution adopted for the present invention to solve the technical problems is: the alkali closure assembly falls in a kind of tealeaves, metal material is made, comprise inner casing (6) and shell (5), it is characterized in that: inner casing (6), external form becomes the round table-like of upper and lower opening, it is upper along the large 2～4cm of (14) diameter that round platform upper end open (1) diameter 10～13cm, round platform lower ending opening (13) diameter compare the tealeaves baking bucket that is equipped with; Shell (5), external form become bottomless coniform.
The alkali closure assembly falls in described tealeaves, it is characterized in that, inner casing (6) and shell (5) all are double-decker, fill aluminosilicate fiber cotton and sealing in the middle of the double-decker, inner casing aluminosilicate fiber cotton layer (9) thickness and shell aluminosilicate fiber cotton layer (12) thickness all are 2～3cm; When alkali closure assembly horizontal positioned fell in tealeaves, among the shaft section figure, the angle of outer shell outer wall and horizontal plane (19) size was equal to angle (20) size of inner casing outer wall and horizontal plane, all is 30～40 °.
The alkali closure assembly falls in described tealeaves, it is characterized in that this device also comprises: temperature-sensing probe (3) and connecting rod (11); Temperature-sensing probe (3), 1, stretch under the inner casing inwall (7) from outer shell outer wall (8), can measure hot air temperature between inner casing inwall (7) and the tealeaves baking bucket (15); Connecting rod (11), 6～8, be distributed between inner casing outer wall (10) and the outer casing inner wall (2), be used for fixedly inner casing and shell gap (4), inner casing and shell gap (4) they are 3～5cm.
The alkali closure assembly falls in described tealeaves, it is characterized in that, temperature-sensing probe (3) links to each other with a temperature controller (17), is subjected to this temperature controller (17) control for the baking bucket provides the heat blower (18) of hot blast.
The tealeaves baking bucket (15) that is equipped with is preferably upper, the upper edge smooth baking bucket circular along (14) of tealeaves baking bucket.
The present invention includes and use above-mentioned tealeaves to fall the method for alkali cover.
Described using method of falling the alkali closure assembly is characterized in that comprising the steps:
(a). the alkali cover is fallen in tealeaves be placed on the tealeaves baking upper edge of bucket (14).
(b). set temperature controller (17) temperature is 120～130 ℃, starts heat blower (18), produces hot blast.
(c). tealeaves falls after air themperature reaches design temperature between alkali cover inner casing inwall (7) and tealeaves baking bucket (15), take off tealeaves and fall the alkali cover, after putting into tealeaves to be processed (16), again tealeaves is fallen the alkali cover and be placed on the tealeaves baking upper edge of bucket (14), begin to reduce the Tea Caffeine operation.
(d). tealeaves falls after the alkali closure assembly working time reaches 10～30 minutes, takes off tealeaves and falls alkali cover and tealeaves baking bucket (15), pours out the tealeaves (16) in the tealeaves baking bucket (15).
Alkali closure assembly operation principle falls in described tealeaves, improve tealeaves baking bucket (15) interior hot blast temperature, so that falling in tealeaves, the inner casing inwall (7) of alkali closure assembly is higher than 120 ℃ with tealeaves baking bucket (15) intermediate heat air temperature, utilize caffeine to lose the crystallization water and begin distillation, 120 ℃ of significant characteristics of distillation at 100 ℃, so that the distillation of the caffeine in the tealeaves (16), and follow hot blast to discharge tealeaves and fall the alkali closure assembly.
The present invention compared with prior art has following advantage: tealeaves falls alkali cover shell (5) and is wrapped in inner casing (6) on every side, hot blast is after round platform upper end open (1) outflow of inner casing (6), also to flow out from inner casing and shell gap (4), improve the temperature of inner casing (6); Simultaneously, because inner casing (6) and shell (5) bilayer, be filled with aluminosilicate fiber cotton in the bilayer as heat-insulation layer, so that inner casing inwall (7) temperature is dried by the fire bucket (15) interior hot blast temperature near tealeaves, the caffeine that distils out from tealeaves (16) in the Tea Processing process can not condense on the inner casing inwall (7).After caffeine entered inner casing and shell gap (4) with hot blast, most with the hot blast outflow, minority was condensed on the outer casing inner wall (2), so that caffeine content is lowered in the tealeaves.Simultaneously, using the alkali closure assembly falls and after, the loss speed of having slowed down tealeaves baking bucket (15) interior air has been avoided in the Tea Processing process too much scattering and disappearing of fragrance, has improved the quality of tealeaves, can be widely used in hanging down the production of caffeine tea.
