Tea sorting, spreading and storing integrated machine
Technical Field
The invention relates to the technical field of tea processing, in particular to a tea classification, spreading and green storage integrated machine with small occupied area.
Background
Spreading, namely the essential procedure of tea processing, spreading fresh leaves picked on the same day under a cool and ventilated environment, and carrying out proper slight withering, so as to moderately reduce the moisture of the fresh leaves, reduce the tension of tea cells, make the leaf stems become soft from crisp, increase the toughness of bud leaves, facilitate subsequent kneading and shaping, on the other hand, after fresh She Jingtan is dehydrated, tea polyphenol is slightly oxidized, water extract and amino acid are increased, green grass flavor is dispersed, some aroma materials are gradually increased along with the spreading process, so that the appearance and the internal quality of the tea are improved, and if the fresh leaves are not spread in time, the fresh leaves are piled together, fermentation effect is easy to generate, the oxidation and the heating of the fresh leaves are seriously influenced, and the tea quality is also influenced.
Because the whole clean processing of tealeaves has been the necessary trend, along with the production volume of tealeaves processing factory is bigger and bigger, the spreading and the storage of fresh leaf become a difficult problem of tealeaves processing factory, the spreading of prior art generally adopts the tiling structure, relies on natural environment to realize the spreading of green, so, the spreading area of fresh leaf is great, and the thickness of fresh leaf layer is great, causes fresh leaf layer inside ventilation failure, and easy heat fermentation of covering influences tealeaves quality and follow-up processing, and simultaneously, the spreading of unit area is also less with storing the quantity of green, has restricted the promotion of production volume and tealeaves quality.
