Embodiment 1

[0038] Such as figure 1As shown, it is a structural schematic diagram of the present embodiment, which includes two sets of far-infrared de-greening machines A and tea leaves automatic feeder B arranged alternately, the first far-infrared de-enzyme machine from right to left, the first tea leaves automatic feeder, The second far-infrared fixing machine and the second tea automatic feeding machine are arranged in sequence. The far-infrared fixing machine A includes a body A1, and a cavity A7 is arranged inside the body A1, and a hopper vibration driven by a vibrating tank motor A4 is arranged at the lower part of the cavity A7. The two sides of groove A2 and hopper vibrating groove A4 are the material inlet and the material outlet respectively, and the hopper vibration groove A2 is provided with an inclination angle of 5 degrees from the material inlet to the material outlet. The upper part of the cavity A7 is equipped with a far-infrared spectrum generating device A5, and the ...

Embodiment 2

[0044] In this embodiment, the difference from Embodiment 1 is that the vibration speed of the hopper vibrating tank A2 of the first tea automatic feeding machine is 600r / min, and the heating temperature of the infrared spectrum generating device is 252°C; The finished tea leaves are put into the second tea automatic feeding machine for cooling and regaining moisture; the cooling and regaining moisture time is 87S, step 3, after the cooling and dampening of the feeding bin in the second tea automatic feeding machine, put the tea leaves into the second infrared The second fixation is carried out in the fixer, and the fixation process is the same as the first fixation process, but the vibration speed of the hopper vibration tank A2 of the second automatic feeding machine is 355r / min, the heating temperature of the infrared spectrum generating device is 235°C, and the rest of the work The principle is the same as in Embodiment 1.

Embodiment 3

[0046] In this embodiment, the difference from Embodiment 1 is that the vibration speed of the hopper vibration tank A2 of the first tea automatic feeding machine is 550r / min, and the heating temperature of the infrared spectrum generating device is 243°C; The finished tea leaves are put into the second tea automatic feeding machine for cooling and regaining moisture; the cooling and regaining moisture time is 80S, step 3, after the cooling and dampening of the feeding bin in the second tea automatic feeding machine, the tea leaves are put into the second infrared The second fixation is carried out in the fixer, and the fixation process is the same as the first fixation process, but the vibration speed of the hopper vibration tank A2 of the second automatic feeding machine is 342r / min, and the heating temperature of the infrared spectrum generating device is 225°C, and the rest of the work The principle is the same as in Embodiment 1.

Abstract

The invention discloses a far infrared fixation set for tea leaves and a fixation method of the far infrared fixation set. The far infrared fixation set is characterized by comprising at least two sets of far infrared fixation machines and two sets of automatic tea leaf feeding machines, which are alternatively arrayed. Far infrared rays are used for carrying out automatic fixation and the tea leaves can be cooled and moistened again after being subjected to fixation carried out by the far infrared fixation machines, so that the effect of carrying out efficient fixation on the tea leaves is achieved.

Description

technical field [0001] The invention belongs to the field of tea deep processing, in particular to a tea far-infrared degreening unit and a degreening method thereof. Background technique [0002] Fixing is the first process of preparing green tea. Its purpose is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, and make tea leaves softened for further processing. At the same time, the tea leaves emit a delicate fragrance by killing greens, so as to promote the formation of good aroma. Therefore, finishing is the key process of preparing green tea, and the key factors affecting the finishing effect are the finishing temperature and the finishing time. With the continuous advancement of science and technology, the requirements for production technology and equipment for tea greening are getting higher and higher. The far-infrared...
