Abstract
The kill out method with mew heat supply new heat supply mode is suitable for various variety of tea. It can produce jade green and aromatic tea without burnt leaf. The present invention makes it possible to raise tea quality, realize continuous production of tea and raise production efficiency of tea.
Description
The present invention is a kind of new method that primary processing of tea completes that relates to.
Completing is the critical process of decision green tea and yellow tea quality.There are two kinds of fixing methods at present in the world.A kind of for being heat-conducting medium with the metal, the bright leaf of tea contacts with 150-500 ℃ of hot metal surface, to reach the purpose of destructive enzyme.A kind of for being heating medium with the steam, the heat steam of the bright leaf of tea through about 100 ℃ steams and burns, and to destroy the enzyme in the leaf, makes tealeaves keep emerald green color and luster.The former is the fixing method that China generally adopts at present.He belongs to the plane and is subjected to hot mode, and bright leaf touches red-hot metal surface and plays the effect of completing.Fixation time is long to need 4-12 minute.The also difficult control of temperature.If temperature is low slightly, enzyme is destroyed, will cause obstructing the leaf red stain; Temperature is too high, can produce the burnt leaf of focal spot again, influences quality.The latter is the mode that current Japan and Ancient Times in China generally adopt.Because the mobile penetrability of steam, bright leaf contacts with thermal medium is three-dimensional.General of fixation time needs 30-60 second.Because bright leaf increases through steaming blue or green moisture content, and the subsequent handling processing time is prolonged, energy consumption is big.And tealeaves fragrance is simple and elegant, strong odor types such as " grain perfume (or spice) ", " fragrance of a flower " that the variation of shortage high-temperature process heat chemistry forms, " camerlsed ".
The present invention adopts hot-air kill out method, can overcome the shortcoming of above-mentioned two kinds of fixing methods, and keep its advantage.This method according to raw material is old tender and water content is different, provides 110-190 ℃ adjustable hot blast by heat-exchange devices such as hot-blast stove or electric heaters.With air blast with the hot blast input device that completes.Bright leaf is is evenly thrown something and fed on metal conveyer belt with eyelet or interlayer elongated slot.Nationality helps runner or vibrating transportation mode, and hot gas is constantly imported tea by eyelet and is heated.Because of the different fixation times of raw material can be regulated by adjusting transporting velocity.Tealeaves must often or off and on stir in being subjected to thermal process, so that it is more even to be heated.Adopt hot air water-removing, in processing, avoid burnt and become, complete evenly so can guarantee bright leaf.The emerald green soup of product leaf is clear, keeps the strong odor type of roasted green tea tool.Thereby improved green tea quality.Help the serialization operation simultaneously, improve the production work efficiency.
Claims (3)
1, a kind of fixing method that utilizes hot blast for pyrogen.
2,, provide 110-190 ℃ adjustable hot blast to water-removing leaves according to described hot-blast stove or the electric heating heat-exchange device of utilizing of claim 1.By air blast hot blast is imported.
3, according to claim 1, bright leaf often must be done in completing or intermittence is stirred, in order to being heated evenly.
