Description

Drying equipment for tea production

Technical Field

The invention relates to tea production equipment, in particular to drying equipment for tea production.

Background

Tea leaves need to be dried after production, and the existing drying treatment has three forms, namely drying, stir-frying and sun-drying.

The drying process of green tea generally comprises the steps of drying and then frying. Because the water content of the rolled tea leaves is still high, if the tea leaves are directly fried to be dry, the tea leaves can be quickly agglomerated into lumps in the pot of the frying machine, and the tea juice is easy to adhere to the wall of the pot. Therefore, the green tea is dried first, so that the water content is reduced to meet the requirement of pan-frying. The drying of the black tea is to bake the fermented tea blank at high temperature to evaporate water rapidly to achieve quality-guaranteeing dryness.

When drying black tea and green tea, both were dried by oven drying. Most current drying equipment all uses drum-type drying equipment to dry, adopts this kind of mode to dry, though tealeaves can dry while rotatory, but at the cylinder rotation in-process, tealeaves can produce and pile up to when leading to the tealeaves that is located the outside to be dried, the inside of inboard tealeaves still contains a large amount of moisture, thereby leads to the stoving effect poor.
