Description

Manufacturing method of compressed tea by single brewing process

Technical Field

The invention relates to the field of compressed tea manufacturing, in particular to a manufacturing method of a single-brewing process compressed tea, which is suitable for pressing various types of fermented tea into small compressed tea with various shapes.

Background

Compressed tea is brick-shaped or tea in other shapes which is prepared by taking black raw tea, old green tea, chateau tea and other suitable raw tea as raw materials and processing the raw materials through typical processes of pile fermentation, steaming, pressing and the like. Most varieties of compressed tea are relatively coarse and old, the color of dry tea is dark brown, and the color of soup is bright yellow or bright red. The compressed tea has the characteristics of good moisture resistance, convenience in transportation and storage, mellow tea taste, suitability for weight reduction and the like.

Most of the compressed tea produced at present is brick tea or tea cake, which is solid, and the raw materials are coarse and old, so that the tea juice is difficult to leach when the compressed tea is brewed with boiled water. For drinking, compressed tea must be crushed and cooked in an iron pot or an aluminum pot, and sometimes the tea juice must be thoroughly extracted by stirring during the cooking process. In addition, the operation is complicated, and the dosage of tea dismantling is difficult to control, so that the tea drinking is sometimes over-concentrated or over-light, and the taste of the tea drinking is influenced; in addition, the volume is large, so that the storage and carrying are difficult for a long time. The brick tea or the tea cake prepared by the existing selection and process method of the compressed tea for the tea raw materials in the manufacturing process is generally rough in surface and single in shape, for example, the brick tea or the tea cake is square (as shown in figure 1) and round (as shown in figure 2).

The above problems are worth solving.

The present invention allows for the manufacture of single brew processed compressed tea according to the steps described in example one, example two, and example three. The invention also relates to the steps of the tea making process in the prior art, if necessary, such as: deactivating enzyme, rolling, piling and drying.

De-enzyming: and (3) performing deactivation of enzymes by using steam, namely putting the fresh leaves into a steaming barrel, steaming the fresh leaves in a boiling water pot, and performing steaming for 8-10 minutes until the steam emerges from a cover opening and the leaves become soft. For example, steaming on a boiler steam generator for 1-2 minutes.

Rolling: kneading is carried out twice, and the kneading by a machine is popularized at present. And (3) after the fresh leaves are subjected to enzyme deactivation, kneading the fresh leaves while the fresh leaves are hot to separate the leaves from the tea stems, and kneading the leaves for 1-2 minutes without pressurizing. After rolling, the water content of the tea blank is 65-70%, the tea blank is primarily dried to reduce the water content to 32-37%, the tea blank is rolled for the second time while the tea blank is hot for 5-6 minutes, and light pressure is applied while the tea blank is rolled so as to be rolled into strips without being broken.

Pile fermentation: the pile fermentation method includes natural pile fermentation and heating and moisturizing pile fermentation. The natural pile fermentation is to pile the rolled leaves while the leaves are hot, the pile height is 1.5-2 m, and the pile surface is covered tightly by a mat to keep the temperature and the humidity. After 2-3 days, hot air emerges from the tea pile surface, when the temperature in the pile rises to about 70 ℃, the pile is turned by using a wood fork once, the surface layer of the pile leaves are turned into the core of the pile, and the pile is rearranged into a pile. The temperature of the heap should not exceed 80 ℃, otherwise, the heap leaves will burn out and turn black, and the tea can not be drunk. And after turning the pile, generating water drops condensed from water vapor on the pile surface after 2-3 days, raising the pile temperature to 60-65 ℃ again, and changing the leaf color into tawny or tan, namely the pile fermentation is proper, and opening the pile to remove the coarse stems for secondary drying. The heating and moisturizing pile fermentation is carried out in a specially-built pile fermentation room. The indoor temperature is kept at 65-70 ℃, the relative humidity is kept at 90-95%, the air is circulated, and the water content of the product is about 28%. If the conditions are met, the pile fermentation process only needs 36-38 hours to meet the requirements, the time is short, the pile fermentation quality is good, the total amount of water extract can be increased by 2%, and the color, the fragrance and the taste are good.

And (3) drying: the water content of the tea blank after pile fermentation is more than 30%. The water content of the tea for making the farm is required to reach 12-14%. Therefore, the piled tea blank can meet the requirement only through drying treatment, and the quality can be fixed and the deterioration can be prevented. The drying is carried out twice, the water content of the primary dry leaves reaches 32-37% for the first time, and the water content of the secondary dry leaves is 12-14%. Machine drying is generally employed.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.

The invention is described above with reference to the accompanying drawings, which are illustrative, and it is obvious that the implementation of the invention is not limited in the above manner, and it is within the scope of the invention to adopt various modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other fields without modification.
