Abstract
The invention relates to an efficient and energy-saving oolong tea refined-baking and aroma-enhancing machine. According to the machine, an electric heater is a cylindric thin-shell-type electric heating unit; a baking chamber formed by the inner cavity of the electric heater has uniform temperature distribution; and after tea leaves are added, by utilization of rising thermal currents in an oven body, dehumidification is performed automatically and the temperature distribution is further uniformed without a need of forcing air to flow to produce dehumidification and thermal conduction. Electric heating units of common electrothermal baking ovens conduct thermal to tea leaves through heat conduction of air flow, and therefore high-aroma compounds produced in baking processes are taken away by the rapid-flowing air flow, effective components are prevented from easy accumulation and reaction, and formation of aroma is hindered. The machine provided by the invention overcomes the above disadvantages of the common electrothermal baking ovens. According to the machine provided by the invention, a tea leaf oven is drove by a driving device, and therefore tea leaves can be turned over automatically, and the machine has no disadvantage of large labor intensity as electrothermal baking cages in which tea leaves are turned over repeatedly. By utilization of double-layer heat preservation and insulation layers comprising the inner heating device and a housing, and a heat exchanging manner of unforced convection, the machine provided by the invention has an advantage of significant energy saving effects over the electrothermal baking ovens and the electrothermal baking cages and 30-40% of energy can be saved.
Description
?
Technical field
the present invention relates to the Tea Processing technical field, especially tealeaves electric oven roasting equipment.
Background technology
the technology of curing is one important procedure of oolong tea tradition tea-manufacturing technology, and it not only is controlled to the water content of sampling tea, so that storage, also, due to after tealeaves is heated, can make the internal substance of tealeaves change, and strengthens the distinctive fragrance of tealeaves.The tea grower has a proverb: tea is monarch, and fire is minister, the importance of curing as seen.Current baking method mainly contains that charcoal roasting cage cures (charcoal roasting) and electric dry oven cures (machine roasting) two kinds.
charcoal roasting cage cures (charcoal roasting): it is to have the processing method of certain historical experience in China's Tea Production that charcoal roasting cage cures.Its operating process is complicated, comprises that the charcoal roasting is on fire, burn, cover ash, temperature control etc., and not only time and effort consuming, need again professional and experience, is the tea baking mode that is not easy control.As what carry out Wuyi cliff tea and the single clump of bitter edible plant, cured process, hand-held basketwork brazier adds the tea amount at every turn and is about 5 jin of left and right, and the time of at every turn curing is short four or five hours, long tens hours, and centre will optionally repeatedly turn over tea; Iron Guanyin is spherical tea, the small volume of Unit Weight, and Nei gap, plane is less, so should not too much cure at every turn simultaneously.Two jin of left and right of each carbon-baked Tie Guanyin tea amount are the most suitable, and heat energy can roast tealeaves into deep layer, are penetrated into the base of leaf the inside, smelly blue or green flavor can be evaporated, and improve the harmonious sounds of Iron Guanyin, and the process of curing will optionally repeatedly be turned over tea.So no matter be Wuyi cliff tea or Iron Guanyin, charcoal roasting labour intensity is large, yield poorly, work efficiency is low, operates very loaded down with trivial details.
electric dry oven cures (machine roasting) and utilizes the electric dry oven tea curing, is the most popular tea baking mode of current China, no matter be, all is easy to see the electric dry oven of different styles in tea processing factory or tealeaves retail shop.Electric dry oven is the heat of electro-heat equipment, and the conduction by moving air is added hot baked to tealeaves, and its heat transfer type belongs to Air Flow conduction heating.Because the electric dry oven processing ease, the tea amount cured is also many, time and labour saving, and machine roasting cost is lower, and is suitable for large production application.So the method is subject to numerous tea growers' welcome, apply the most general.
but well-known, the quality of the tea that electric dry oven roasts out can't roast tea with charcoal far away and compare, charcoal roasting liquor color is limpid bright, the dense alcohol of flavour, and strongly sweet aftertaste, fragrance is lasting, not pained, and the larynx rhythm is obvious, specifically its more anti-bubble.The perfume (or spice) when tea that electric dry oven roasts out brews, it is tasteless to drink, and quality is nothing like carbon roasting tea.
why, in the process of curing, fiery merit is the key technique that promotes that the mellow note of anti-bubble of oolong millet paste flavor gradually reveals, refining oolong tea fire merit is the most important key element of baking process.Duration and degree of heating practical function is the degree that makes to produce in tealeaves hot physics chemical action.The duration and degree of heating can affect soup look at the bottom of Appearance color, leaf, affects the soaked length quality of tealeaves; The duration and degree of heating is grasped and suitably can be made up some deficiency of tea leaf quality.The tealeaves of special kinds, it is just right that the duration and degree of heating is grasped, and can set off special note feature.Tea baking always with the long roasting of slow fire for well.Its principle is: the more senior slow fire low temperature length that more needs of tealeaves roasts, and cure is " eating fire " process of oolong tea, and the long roasting of low temperature can produce the high-quality slender joss stick terpene compound of multiple tool, thereby forms the graceful fragrance of oolong tea.Particularly, in the charcoal roasting process later stage, on the roasting cage, add a cover, exactly in order to guarantee the reaction that fragrance generates and to stop fragrance excessive.Slow fire roasts slowly and can also make finished product fragrance hold back Tibetan simultaneously, and flavour is mellow, color and luster is glossy, appearance " frosting " (the appearance frosting is cured exactly tealeaves volatilization aroma substance in process and gathered on tealeaves), and tealeaves is glossy.Especially cure for a long time with charcoal fire low temperature, to improving the high-quality quality of Oolong tea, excellent effect is arranged.Therefore, curing of oolong tea is to dry so simple concept far from, and curing in the oolong tea subtractive process, should qualitatively be the rear journey heat processing technique process to oolong tea, and this heat processing technique has specific specification requirement.
very large problem is, current in oolong tea is produced, and applies the most general electric heating curer, be exactly the reprint of minitype drier in fact, the Essential Action that it rose is dried exactly, can not meet hot worked particular technology requirement after oolong tea, and the tea leaf quality of producing is far away not as good as charcoal roasting tea.Existing electric heating curer defect is: the one, and the electric heating curer is that electric heater unit passes through the air stream heat transfer by heat conduction to tealeaves, the air-flow of rapid flow has been taken away and has been cured the high-quality slender joss stick terpene compound produced in process.The 2nd, the air-flow of rapid flow is difficult for making the active ingredient produced in the tea baking process gather and react, thereby produces more high-quality slender joss stick terpene compound.The 3rd, current tea baking machinery (being mainly electricity roasting case) heat exchange air-flow can not stop, and leakes water very fast, and the time of curing is short, and general electricity roasting case cures the time at three to four hours, and the tealeaves thermal response time is short, also is unfavorable for the formation of tea aroma.The tealeaves appearance that above reason causes existing electricity roasting case to cure non-blooming (the non-blooming explanation of appearance is cured tealeaves volatilization aroma substance in process and can not be gathered on tealeaves), matt, tea flavour is light, is exactly that aroma substance can not accumulate and causes in fact.The transformation that tea baking machinery is carried out, overcome above defect, makes its specification requirement that meets the oolong tea heat processing technique, reaches with charcoal and roast corresponding effect, is the importance of oolong tea mechanism baking process research.
