Tealeaves comes from China, contains multiple nutritional components and effective component in tealeaves, having tea is beneficial to health, now
The people having tea is more and more.The fresh leaf of tealeaves can not directly be drunk, but need just drink by a series of processing.Wither
It is one of step of fresh tea passes processing to wither, and is by the thin stand of tea fresh leaves, evaporates its internal moisture, is changed into wilting from brittle and is withered
Thank to the process of situation.Wither purpose, one is evaporation section moisture, reduces the tension force of tea cell, make leaf stalk soft by embrittlement, increase
Add the toughness of bud-leaf, be easy to knead into bar；The second is a series of of the internal substance in the tea tip are caused due to scattering and disappearing for moisture
Chemical change, to form the certain quality of tealeaves color, establish the basis of material change.
Current method of withering mainly has that Indoor Natural withers, daylight withers and semi-automatic processing, and when withering, tealeaves
It can also be fermented in the case where temperature and humidity is suitable, so withering typically in the case where sunlight is not strong to enter naturally
OK；Semi-automation processing mainly uses withering trough heating deterioration technology.Production at present is upper to be withered using slot type hot blast mostly,
When withering, fresh tea passes are put into withering trough, and hot blast is passed through into withering trough, the temperature into the hot blast in withering trough
Can constantly it scatter and disappear, therefore the hot blast temperature highest having just enter into withering trough, the effect of withering of the fresh tea passes at this is more preferable, and is put into and withers
The fresh tea passes in groove of withering will not be stirred, therefore the effect of withering of the fresh tea passes of withering trough everywhere differs.It can make during due to withering
Temperature rise around tealeaves, and the moisture evaporation in tealeaves can raise the humidity around tealeaves, now tealeaves can be sent out
Ferment, fermentation can change the mouthfeel of tealeaves；And it is related to temperature and moisture in air, oxygen content to ferment.
In order to solve this problem, notification number discloses a kind of cellular-type tealeaves for CN104255960B Chinese patent and withered
