Description

Technical Field

[0001] The utility model relates to the field of tea processing, in particular to a vibration type tea withering device. Background Art

[0002] The processing steps of tea vary depending on the type of tea, but generally include the following steps: picking, withering, killing green, rolling, fermentation, drying, refining, etc. Withering is a process that allows tea leaves to lose water naturally and soften the leaves, which helps to enhance enzyme activity and subsequent processing. Killing green, also known as shaking green, is a process that destroys and passivates the oxidase activity in fresh leaves at high temperature, inhibits the enzymatic oxidation of tea polyphenols in fresh leaves, evaporates part of the water in fresh leaves, softens the tea leaves, and facilitates rolling and forming. At the same time, it emits a green smell and promotes the formation of a good aroma. In the prior art, after the tea leaves are withered by the withering device, they often need to be manually put into a sieve to manually shake the green leaves. However, due to the decreasing number of tea processing practitioners year by year and the low efficiency of manual shaking green, it is impossible to achieve fast and efficient tea processing and production. Therefore, there is an urgent need for an automated machine that can complete the withering and shaking green processes at the same time to improve production efficiency. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in combination with the drawings of the specific embodiments of the utility model. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1-6 An embodiment shown provides a vibrating tea withering device, including a withering trough 1, a fan 2, a ventilation plate 3, a lifting plate 4 and a lifting cylinder 5. The air outlet of the fan 2 is connected to the bottom of the withering trough 1 for blowing air into the withering trough 1. The air blown by the fan 2 enters the withering trough 1 through the bottom of the withering trough 1 to dry and dehydrate the tea leaves. The ventilation plate 3 is arranged in the withering trough 1. It should be noted that ventilation holes can be provided on the ventilation plate 3 so that the air blown by the fan 2 can penetrate the ventilation plate 3. A plurality of equidistantly arranged ventilation holes are provided on the ventilation plate 3. Rectangular holes 6, each of which has a corresponding lifting plate 4, and each of which has a lifting cylinder 5 connected to its bottom. The lifting cylinder 5 is used to drive the lifting plate 4 to move up and down. The lifting cylinder 5 is arranged at the bottom of the withering tank 1, and the lifting cylinder 5 is configured to start in sequence. A gauze 8 is laid on the ventilation plate 3. When the lifting plate 4 is at the lowest point of its lifting stroke, the four side walls in the horizontal direction are in close contact with the ventilation plate 3 and its upper surface is flush with the upper surface of the ventilation plate 3. It should be noted that the gap between the lifting plate 4 and the ventilation plate 3 is set to be smaller than the width of the tea leaves to prevent the tea leaves from falling from the gap between the lifting plate 4 and the ventilation plate 3. By limiting the upper surface of the lifting plate 4 to be flush with the upper surface of the rectangular hole 6, the gauze 8 can be laid flat on the ventilation plate 3, which is convenient for the tea leaves to be laid flat on the gauze 8.

[0024] The working principle and use process of this embodiment:

[0025] When using the vibration tea withering device, the tea leaves are first laid flat on the gauze 8 in the withering tank 1, and the fan 2 is started. The fan 2 blows air from the bottom of the withering tank 1. Since the ventilation plate 3 is air-permeable, the wind can penetrate the ventilation plate 3 to dry and wither the tea leaves laid on the gauze 8. After withering is completed, the fan 2 is turned off, and the lifting cylinder 5 is started in sequence. The lifting cylinder 5 drives the lifting plate 4 to rise and fall. When the lifting plate 4 rises and falls, the gauze 8 at the corresponding position will be driven to rise and fall, driving the tea leaves to be thrown into the air and fall on the gauze 8, so that the tea leaves collide and stimulate the aroma of the tea leaves. The lifting cylinder 5 is started in sequence, and the lifting speed of the lifting cylinder 5 needs to be set relatively fast, so that the tea leaves can collide when they are pushed up and fall down, driving the corresponding lifting plate 4 to start in sequence, so that the gauze 8 forms a wave-shaped undulation, so that the tea leaves laid on the gauze 8 can be thrown into the air and fall on the gauze 8, and finally the lifting cylinder 5 is stopped, and the tea leaves complete the shaking process.

[0026] Embodiment 2

Specifically, Figure 4-6 As shown, an overlap portion 7 is provided on the inner cavity side wall of the withering trough 1, and the ventilation plate 3 is provided on the overlap portion 7. The ventilation plate 3 is installed through the overlap portion 7, firstly, the installation stability of the ventilation plate 3 is ensured, and secondly, it plays a role of limiting. When the staff is installing the ventilation plate 3, they only need to align the ventilation plate 3 with the overlap portion 7 and press downward. When the ventilation plate 3 is in contact with the overlap portion 7, the ventilation plate 3 can be ensured to be installed in place.

[0028] Embodiment 3

[0029] This embodiment is developed on the basis of the above embodiment to solve the installation problem of the gauze 8. Specifically, Figure 1 As shown, the gauze 8 covers the four side walls of the withering trough 1 and its edges are fixedly connected to the outer sides of the four side walls of the withering trough 1. It should be noted that the gauze 8 is made of elastic material, so that when the edge of the gauze 8 is fixed, the part in contact with the lifting plate 4 can also be lifted up due to elasticity, and the gauze 8 will not be unable to work because the edge is fixed.

[0030] Embodiment 4

[0031] This embodiment is developed on the basis of the above embodiment to solve the ventilation problem of the ventilation plate 3. Specifically, Figure 3 As shown, the ventilation plate 3 is provided with a plurality of ventilation holes 9. By providing the ventilation holes 9, hot air can pass through the ventilation plate 3 to dry the tea leaves.

[0032] Furthermore, the diameter of the ventilation hole 9 is 2-5 mm. The ventilation hole 9 of this diameter will not cause the tea leaves to fall out of the hole while allowing wind to pass through to complete the withering work.

[0033] Embodiment 5

[0034] This embodiment is developed on the basis of the above embodiment to solve the control problem of the lifting cylinder 5. Specifically, Figure 4 As shown, the lifting cylinder 5 is electrically connected to the control board 10. By sequentially setting the lifting cylinder 5 start-up on the control board 10, the lifting cylinder 5 is automatically controlled. It should be noted that how the control board 10 controls the lifting cylinder 5 is a very mature technical means for those skilled in the art. Therefore, in this embodiment, no further limitation is made on how the control board 10 controls the lifting cylinder 5.
