Problems solved by technology

[0012] However, practice has proved that when using the existing greening and forming equipment to make tea leaves, it is impossible to achieve the alternation of greening and shaping like hand-made, so the tea produced cannot be compared with the high-grade tea leaves made by traditional handwork in terms of quality and appearance.

Embodiment 1

[0043] In this embodiment, the special equipment designed according to the flat tea forming process of the present invention is as follows: figure 1 , 2 As shown, there are two head boxes 2-1 and 2-2 at both ends of the frame 1, and two driving wheels 3-1 and 3-2 are installed on the head boxes 2-1 and 2-2 respectively. The transmission wheel 3-2 is driven by the motor 4 installed in the head box 2-2. A conveyor belt 5 is surrounded between the transmission wheels 3-1 and 3-2, and the middle part of the conveyor belt 5 is sealed up and down. The channel cavity 6 is equipped with flat microwave suppressors 8 at both ends of the channel cavity 6 respectively.

[0044] Install the relevant heating device on the side of the conveyor belt 5 in the channel cavity 6 in the following way:

[0045] ——Place the first group of microwave generators 7-1 and the first group of far-infrared heaters 13-1 on the upper part of the first high temperature zone at the entrance of the channel cavity 6; ...

Embodiment 2

[0065] The flat tea finishing process and special equipment of this embodiment are basically the same as those of the first embodiment, the difference is:

[0066] 1. In step 2), the temperature is increased to 115°C;

[0067] 2. In step 3), keep the temperature at 85°C;

[0068] 3. In step 4), the temperature is raised to 105°C;

[0069] 4. In step 5), keep the temperature at 85°C;

[0070] 5. The ratio of the gap between the first pair of pressure rollers and the second pair of pressure rollers is 200%;

[0071] 6. There are two pairs of pressing roller shaping mechanism, that is, the third pair of pressing roller shaping mechanism 9-3 in the first embodiment is omitted. This can be more energy saving and cost reduction, and shorten the working hours and improve work efficiency.

[0072] Experiments have proved that the use of the flat tea curing method and special equipment of the present invention creatively combines the existing channel microwave curing machine with the conveyor rol...

Abstract

An apparatus dedicated for heating and shaping the flat tea is composed of machine frame, channel cavity, endless conveying belt passing through said channel cavity, more than 3 sets of microwave generator installed at least one side of said conveying belt, more than two sets of far infrared generator close to said microwave generators, and more than two pairs of pressing rollers arranged on and under said conveying belt. Its process for preparing flat tea is also disclosed.

Description

Technical field [0001] The invention relates to a technological method of tea processing, and also to a special equipment for realizing the method, belonging to the technical field of tea processing. Background technique [0002] As we all know, curing and forming are an important part of the tea processing technology. In traditional tea processing, curing and forming are carried out step by step. The purpose of curing is to make the various biological oxidases in the tea lose their activity at high temperatures, and to avoid subsequent During the production process, a biochemical reaction that is unfavorable to the quality of the tea occurs inside the tea; after the curing is completed, it is further processed and dried to form a finished tea. [0003] For a long time, the finishing and forming processes have been manually operated. For processing high-end tea, the typical operation steps are: [0004] 1. Put fresh leaves in the wok when heated to a suitable temperature, and stir-f...
