Problems solved by technology

[0003] During the processing of Fuzhuan tea, affected by the stability of the steam pressure, the uniformity of the water content of the tea leaves and the cleanliness of the processing environment, there will often be bacterial contamination in the subsequent tea brick flowering process due to improper steaming of the tea during the steaming process. The problem not only seriously affects the pass rate of product quality, but also the contamination of bacteria often appears inside the tea bricks, which also brings great difficulty to quality inspection.
Due to the needs of the flowering process, Fu brick tea has a low compactness when pressed into tea bricks, resulting in a long setting time and occupying a large number of molds, which affects subsequent production.
In addition, due to the restriction of the flowering environment inside the tea brick, the water loss is too fast, which inhibits the growth of golden flower fungus, resulting in poor taste quality of this part of the tea

Embodiment Construction

[0021] Below in conjunction with embodiment the present invention is described in further detail:

[0022] Taking the processing of 1 kg of Fuzhuan tea as an example

[0023] (1) Oding: After the blended raw tea is steamed at high temperature, it is transferred to the Oudui bin for Ozu.

[0024] (2) Sealing and regaining moisture: Put the piled raw materials into a sealed moisture regaining tank, spray tea juice while stirring, and let it stand for 1 hour to regain moisture after stirring, so that the water content of the tea leaves is controlled at about 30%;

[0025] (3) Weighing: Calculated on the basis of 1% processing loss, weigh 1.568 kg of raw tea after moisture recovery;

[0026] (4) Pressing: Pour the weighed raw tea into the mold, and control the pressing density of tea bricks at 0.7g / cm 3 ;

[0027] (5) Vacuum packaging: the pressed Fuzhuan brick tea is withdrawn from the mold and wrapped with a vacuum packaging machine;

[0028] (6) Autoclaving: The wrapped tea...

Abstract

The invention provides to an improved Fuzhuan tea processing method and relates to the field of tea leaf processing. The improved Fuzhuan tea processing method is characterized by comprising the processing steps of pile fermentation, sealing moisture regaining, weighing, pressing, vacuum packaging, high-pressure sterilization, cooling shaping, unpacking, high-humidity mouldy spot appearing, aroma increasing drying and inspection packaging. Compared with traditional Fuzhuan tea processing, the improved Fuzhuan tea processing method has the advantages that by the mode of sealing moisture regaining, the purpose of softening tea leaves is achieved, and the uniformity of the moisture content of the tea leaves is effectively controlled; brick tea is quickly released from molds after being pressed, and thus the using quantity of the molds is reduced; the humidity of different mouldy spot appearing stages is controlled, so that golden spots inside brick tea grow more uniformly, the taste and quality of the tea leaves are improved, and overgrowing of contaminating bacteria on the surface of brick tea under the high-humidity environment is also prevented through irradiation of ultraviolet lamps.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to an improved Fuzhuan tea processing method. Background technique [0002] Fuzhuan tea is a fully fermented tea. It is currently the dark tea product with the most complicated processing technology, the longest production cycle and the most unique technology among all teas. Fuzhuan brick tea is made from black hair tea, which is processed through screening, steaming, heaping, pressing, blooming and drying. Among them, blooming is the key process for the formation of the unique quality of Fuzhuan brick tea. The environmental conditions promote the reproduction of the coronoid fungus in tea bricks with a certain degree of tightness, forming a golden-yellow closed capsule, commonly known as "golden flower". The taste, aroma and color of Fuzhuan tea can be made different from other dark tea products through flowering process. [0003] During the processing of Fuzhuan tea, affected by th...
