Embodiment

[0027] A kind of preparation method of green tea concentrated liquid, is raw material with the bright leaf of one bud three leaves of Huangshan tea tree, comprises the following steps:

[0028] S1, fresh leaf treatment:

[0029] First, the picked fresh leaves are quick-frozen at -15°C, and then the quick-frozen fresh leaves are spread on the conveyor belt of the microwave greening machine with a thickness of 3 to 4 cm, and the fresh leaves are subjected to microwave action for 4 minutes.

[0030] Then put the leaves after microwave action into the segmented composite de-enzyming machine, the initial leaf-throwing temperature is 280°C, the initial de-enzyming time is 1-2min, then slowly cool down to the de-enzyming temperature of 140°C, and the subsequent de-enzyming time is 3-4min. The segmented compound de-greening machine is a horizontal single-screw compound de-greening machine. When working, the screw pushes the blades to convey to the discharge port, and the screws are arra...

Abstract

The invention discloses a preparation method of a concentrated green tea solution. Fresh leaves of one-bud-three-leaf tea trees planted in Huangshan are taken as a raw material, and the preparation method comprises steps of fresh leaf treatment, deionized water preparation, low-temperature extraction, rough filtration, fine filtration, ultrafiltration, concentration, blending, sterilization and sterile filling. A special 20-40-mesh raw material is prepared by selection of excellent tea tree variety, sharp freezing, microwave thawing and fixation, buffeting, cutting and screening, then pH is regulated, under the actions of vortex produced by tank rotation and dynamic water flow produced by tank top spraying, tea polyphenol, amino acid, caffeine, protein and pectin which determine tea soup quality are dissolved out in a certain ratio, dissolution rate of effective components in tea is increased, extraction time is shortened, and extraction efficiency is improved.
