Embodiment 1

[0017] Example 1: Reference figure 1 . Tea withering treatment equipment mainly includes rack 1, electric control box 2, lifting conveyor belt 3 installed on rack 1, box body 4, cold and hot air supply device, discharge conveyor belt, and circulating return device. Combine below Figure 1 to Figure 3 The structure of this embodiment is described in detail:

[0018] The lifting conveyor belt 3 is installed on the front upper part of the frame 1 through a bracket, and the box body 4 is fixedly installed on the frame 1 at the rear of the lifting conveyor belt 3. The driving motor 30 fixedly mounted on the frame 1 is in transmission connection with the material lifting conveyor belt 3, and the driving motor 30 drives the material lifting conveyor belt 3 to rotate through a belt. The loading end of the lifting conveyor belt 3 is provided with a hopper 3a, and the discharge end extends through the side plate of the box body 4 into the upper part of the box body 3; the lifting conveyo...

Embodiment 2

[0026] Embodiment 2: As shown in Figure 5. The difference between this embodiment and embodiment 1 is that the discharging conveyor belt 12 is directly arranged on the inner bottom of the tea processing chamber 6 below the discharge port end of the lowermost conveyor belt 98, and on both sides of the tea processing chamber 6 Correspondingly, an opening 26 for the discharge conveyor belt 12 to pass is provided, and both ends of the discharge conveyor belt 12 extend out of the tea processing chamber 6 through the corresponding openings 26. The tea leaves sent by the lowermost conveyor belt 98 directly fall onto the discharge conveyor belt 12, and no feed opening is provided. The rest of the structure is the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a tea withering machine, comprising a frame, an electric cabinet and a case on the rear part of the frame. A feeding and conveying belt for delivering tealeaves into the case is arranged on the frame in front of the case; small vent holes are densely arranged on the conveying belt, and a heating and cooling air supplying device is positioned under the conveying belt; the case is divided into a tealeaves treating chamber and an air treatment chamber by a separating plate with respective air inlets and outlets at both sides; the air treatment chamber is provided with a temperature and humidity treatment device for recirculation air, and a blower; the blower is connected with the air outlets of the separating plate; the tealeaves treating chamber is provided with an air exhausting device and a multi-layer tealeaves distributing and conveying belt; the tealeaves distributing and conveying belt is used to support the tealeaves on the feeding and conveying belt, and deliver downward the tealeaves layer-by-layer; a conveying belt for the discharge tealeaves is arranged at the lower part of a discharge port of the lowest tealeaves distributing and conveying belt; a circulating and back-feeding device for delivering the tealeaves to a hopper is arranged between one end of the conveying belt for the discharge tealeaves and the hopper; a receiving chute is positioned below the other end of the conveying belt for the discharge tealeaves; a temperature and humidity sensor connected with an input end of a control system is arranged in the tealeaves treatment chamber. The tea withering machine has the advantages of saved space and excellent withering effects.

Description

Technical field [0001] The invention relates to the field of tea-making machinery, in particular to a device for withering treatment of green tea after picking. Background technique [0002] Depending on the type of tea, the production process is different, but the withering treatment is the first process that all tea-making processes must go through, and it is also the basic process that forms the quality of tea. Withering refers to the process of losing water to the fresh tea leaves after picking for a period of time, causing the hard and brittle fresh tea stalks and leaves to appear wilting and withering, making the leaves soft, plastic, and easy to shape. Withering is not only a physical loss of water, but also a process of chemical changes in the content; one is to evaporate part of the water, reduce the tension of the tea cells, make the leaf stems from brittle to soft, increase the toughness of the buds and make it easier to twist. The second is a series of chemical chang...
