Abstract

The present invention discloses a production and processing method of red date black tea, and belongs to the technical field of black tea preparation. Technical essentials of the production and processing method include the following steps: (1) picking tea leaves; (2) withering the tea leaves to a water content of 52-55%; (3) putting withered tea leaves and red date pulp into a rolling machine tobe rolled, (4) deblocking the rolled tea leaves; (5) fermenting: putting the deblocked tea leaves in a fermentation chamber to perform stacking fermentation with the fermentation time being 2.5-3.5h,and spraying red date water according to different stages, thereby obtaining tea bases; and (6) drying: subjecting two times of drying to the tea bases, putting red date pulp granules on a screen meshto be put together on the bottom of a drying box after the first time of drying, and then carrying out the second time of scenting-drying, thereby obtaining semi-finished red date black tea. The invention aims to provide the production and processing method of red date black tea characterized by scientific preparation method, fresh, sweet and strong taste and rich nutrition for the preparation ofred date black tea.
