Abstract

The invention discloses a zinc-selenium tea processing technology. The zinc-selenium tea processing technology comprises tea leaf classification, tea leaf processing, tea leaf mixing, rolling, fixation, re-rolling and disentangling, fermentation, reshaping and discharge and specifically comprises the steps that step one, in the tea leaf classification, automatic tea-green separation is performed through a screen, tender leaves and old leaves which are classified are cleaned, and impurities are removed for standby application; step two, in the tea leaf processing, the tender leaves and the old leaves obtained in the step one are respectively processed for standby application; step three, in the tea leaf mixing, the tea leaves prepared in the step two are mixed according to the 1:10 weight ratio of old leaf residues to the tender leaves; step four, rolling is performed; step five, fixation is performed; step six, re-rolling and disentangling are performed; step seven, the fermentation is performed; step eight, the reshaping is performed; step nine, the discharge is performed. The tea leaves reshaped and processed undergo fixation in a fixation machine, and drying and sterilization are performed in the process of pushing the tea leaves out of the fixation machine. The zinc-selenium tea processing technology can well retain zinc-selenium elements, meanwhile the processing time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a process for processing zinc-selenium tea. Background technique [0002] Zinc-selenium tea refers to organic ecological tea rich in zinc and selenium. The zinc content in the soil in Fenggang County is 95.3 mg / ㎏, and the selenium content is 2.5 mg / ㎏; the average zinc content in the tea grown in these soils is 40-100 mg / kg, and the average selenium content is 0.25-3.50 mg / kg. ㎏, and it is entirely derived from the natural adsorption of zinc and selenium in the soil by tea trees. Zinc is known as the "spark of life", and selenium has the reputation of "moon element" and "marriage harmony element". Drinking zinc-selenium tea has more health care effects than drinking ordinary tea. In the existing zinc-selenium teas, most of them are green teas, because black teas have more fermentation steps than green teas, so it is difficult to keep the zinc and selenium elements from being lost....
