example 1

[0012] 1) Picking of fresh leaves: the raw materials of sweet-flavored black teas require higher tenderness. Fuding Dahao tea and Fuding Dabai tea with one bud and one fresh leaf are used as raw materials for picking in May. , picking from 9 to 10 o'clock in the morning; no picking on rainy days.

[0013] 2) Withering of fresh leaves: the withering room adopts a temperature and humidity control system consisting of a cabinet-type 3-horsepower air conditioner and a DY-690EB humidity machine (manufactured by Ningbo Deye Daily Appliance Technology Co., Ltd.). The humidity is controlled at about 60%; the withering time is 11 to 11.5 hours, until the water content is 51% to 55% (depending on different production seasons, the basic principle is "old leaves wither tenderly" and "young leaves wither old". The degree of withering of spring tea should be heavy, and the water content should be controlled at 50% to 55% to eliminate the green smell), so that the leaves are wrinkled and the...

example 2

[0019] 1) Picking of fresh leaves: The raw materials of sweet-flavored black teas require higher tenderness. For picking in August, fresh leaves with one bud and two leaves of Fuding Dahao and Fuding Dabai are used as raw materials. The picking time is from 3 pm to 6 pm on sunny days. The fresh leaves picked are of good quality; they are not picked on rainy days.

[0020] 2) Withering of fresh leaves: the withering chamber adopts a temperature and humidity control system consisting of a cabinet-type 3-horsepower air conditioner and a DY-690EB humidity machine (manufactured by Ningbo Deye Daily Appliance Technology Co., Ltd.). The temperature is controlled at about 18°C ​​and the relative humidity Control at about 60%; withering time 10-10.5 hours, withering to 55-56% water content (depending on different production seasons, the basic principle is "old leaves are tender and withering", "young leaves are old and withering". Summer and autumn tea It should be light, the water con...

Abstract

The invention belongs to a tea leaf processing technology and concretely relates to a method for processing a sweet and fragrant black tea through utilizing a temperature and humidity control system. The fragrance and the taste of a common black tea are unstable because of the different kinds of tea trees and the different processing technologies, so the improvement of the economic benefit of the black tea is influenced. Each of Fuding Dabaicha tea leaves and Fuding Dahaocha tea leaves has a high amino acid content and a high phenol/ammonia ratio. The method treats Fuding Dabaicha tea leaves and Fuding Dahaocha tea leaves as raw materials and utilizes the temperature and humidity control system to process in order to make the black tea have the advantages of excellent quality, stout, strong and more-hair profile, and stable fragrance. The sweet and fragrant black tea can be prepared through the selection of the kinds of the tea trees, the application of the temperature and humidity control system, and the standard-strict processes comprising fresh leaf pickling, withering, rolling, fermenting, drying and the like.

Description

technical field [0001] The invention belongs to tea processing technology, and in particular relates to a method for processing sweet-flavor black tea by utilizing a temperature and humidity control system. Background technique [0002] The flavor and taste of ordinary black tea are not stable due to the variety of tea trees and processing techniques, which affects the improvement of its economic benefits. Fuding Dabai tea and Fuding Dahao tea have high amino acid content and high phenol-ammonia ratio. This method uses Fuding Dabai tea and Fuding Dahao tea as raw materials, and uses the temperature and humidity control system to process and produce black tea with good quality and good shape. It is plump and thick, with a stable fragrance. Contents of the invention [0003] The technical solution adopted by the present invention is: a method for processing sweet-flavor black tea by using a temperature and humidity control system, which is characterized in that it includes ...
