Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea drying machine for automatically turning over tea leaves. Background Art

[0002] Tea refers to the leaves and buds of the tea tree, which can be brewed directly with boiling water. Tea contains catechins, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients that can improve human health. Therefore, tea drinks are known as "one of the three major beverages in the world." In the process of making tea, the tea leaves need to be dried to remove moisture from the tea leaves for easy storage.

[0003] However, the existing tea dryer only places the tea leaves in the drying box for drying during the drying process, and lacks turning the tea leaves, so that the tea leaves in the lower layer cannot be heated evenly, resulting in uneven heating and inconsistent dryness of the upper and lower layers of tea leaves, which affects the taste and aesthetics of the tea leaves, and even causes the upper layer of tea leaves to become mushy, thereby bringing inconvenience to users and failing to meet the users' needs.

[0004] Therefore, corresponding improvements are made to the deficiencies of the existing tea drying machine. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1 As shown, a tea dryer for automatically flipping tea leaves comprises a box body 1, which is divided into two left and right cavities by a vertical partition 11, and a plurality of drying bases 13 are arranged in one of the cavities in the box body 1, and the end faces of the drying bases 13 are fixedly connected to the box body 1 and the vertical partition 11, and a circular tea sieve 5 is arranged on the drying base 13; a flipping mechanism 3 is arranged on the upper end of the circular tea sieve 5, and the two ends of the flipping mechanism 3 are rotatably arranged on one side of the drying base 13 and the vertical partition 11; wherein the flipping mechanism 3 comprises a first flipping claw 31 and a second flipping claw 32, the first flipping claw 31 and the second flipping claw 32 are coaxially mounted, and the second flipping claw 32 is sleeved on the periphery of the first flipping claw 31, and the flipping mechanism 3 is connected through a hollow shaft, a solid shaft and a driving mechanism, the driving mechanism is arranged in another cavity in the box body 1, and the driving mechanism can simultaneously drive the first flipping claw 31 and the second flipping claw 32 to rotate in opposite directions.

[0024] In the prior art, the tea leaves are not turned evenly or thoroughly, and the tea leaves are not only scattered but also uneven in thickness after turning, which leads to inconsistent drying effect of the tea leaves as a whole and affects the drying quality of the tea leaves. The innovation of the utility model is to drive the first turning claw 31 and the second turning claw 32 to rotate in opposite directions through a driving mechanism. With such a design, when the tea leaves are turned over by the second turning claw 32 during drying, the first turning claw 31 turns over in the opposite direction and turns the turned tea leaves back again. Such a design can avoid the problems of excessive turning, deviation of the position of the tea leaves, uneven turning and inconsistent thickness of the tea leaves during turning, and thus the position of the tea leaves in the drying box will not change greatly when turning over, but only the tea leaves at the bottom will be turned over thoroughly, and the turned tea leaves will be evenly distributed and dried evenly, thereby improving the drying efficiency and quality requirements of the tea leaves. Compared with the single-direction rotation turning adopted by most turning mechanisms in the prior art, the turned tea leaves will not be distributed everywhere, and the turning is more thorough and evenly distributed.

[0025] The driving mechanism includes a motor 2, a first gear 21, a second gear 22 and a third gear 23. A mounting base 12 is provided in the housing 1, and a bearing seat 121 is fixed on the mounting base 12. The motor 2 is fixed on the mounting base 12, and the motor 2 is connected to the first gear 21 through the first central shaft 211, and the first gear 21 and the second gear 22 are meshed and connected; the second gear 22 is connected to the first solid shaft 221, and the third gear 23 is an internal gear, and the first gear 21 and the third gear 23 are meshed and connected; the third gear 23 is connected to the first hollow shaft 232, and the first solid shaft 221 is sleeved on the inner wall of the first hollow shaft 232, and one end of the first solid shaft 221 and the first central shaft 211 are fixed to the bearing seat 121 through a bearing. On, the first center axis 211 and the other end of the first hollow shaft 232 are fixed on the vertical partition 11 through bearings; one end of the first flip claw 31 is detachably connected to the first solid shaft 221, one end of the second flip claw 32 is detachably connected to the first hollow shaft 232, the other end of the first flip claw 31 is detachably connected to the second solid shaft 222, the other end of the second flip claw 32 is detachably connected to the second hollow shaft 233, the second hollow shaft 233 is sleeved on the second solid shaft 222, and the second solid shaft 222 is rotatably connected to the drying base 13.

[0026] The utility model realizes the requirement of rotating the first flip claw 31 and the second flip claw 32 in opposite directions by using the transmission mode of the motor 2 and the gear set and the meshing of the three gears. Such a structural design is reasonable and has high transmission efficiency. Only one motor 2 is needed to realize the rotation of the first flip claw 31 and the second flip claw 32. Moreover, the flip mechanism 3 is detachably connected by the hollow shaft and the solid shaft, which has a simple structure and is easier to disassemble and install.

[0027] Furthermore, a circular turntable 4 is provided on the drying base 13 and rotated by a rotating shaft 42, a circular tea sieve 5 is fixed on the circular turntable 4, and a helical gear 41 is provided on the bottom side of the circular turntable 4; the driving mechanism also includes a fourth gear 24, the third gear 23 is provided with external teeth, the external teeth of the third gear 23 are meshed and connected with the fourth gear 24, the fourth gear 24 is connected to a fifth helical gear 25 through a second center shaft 241, and the fifth helical gear 25 is meshed and connected with the helical teeth 41 of the circular turntable 4; the helical teeth 41 at the other end of the circular turntable 4 are meshed and connected with the sixth helical gear 26.

[0028] In order to make the tea leaves turn over more thoroughly and evenly when drying, the utility model designs a rotatable circular turntable 4. Through the meshing transmission of the gear set, the driving force of the motor 2 is transmitted to the fourth gear 24 and the fifth bevel gear 25 through the third gear 23. Finally, the fifth bevel gear 25 is meshed and connected with the bevel teeth 41 of the circular turntable 4, so that the rotation of the motor 2 finally realizes the rotation of the circular turntable 4. Such a design layout is reasonable, and the combination of the gear set is fully utilized to realize the movement of multiple mechanisms in different spaces. While the circular turntable 4 drives the circular tea sieve 5 to rotate, the first flip claw 31 and the second flip claw 32 are also rotating, so that the tea leaves can be distributed more evenly and thoroughly during the flipping process, and finally the process requirements of tea drying are effectively improved.

[0029] The bottom of the circular tea sieve 5 is a filter surface that allows heat flow to pass through; a plurality of airflow holes 131 are provided on the drying base 13. When the tea leaves on the circular tea sieve 5 are being dried, the hot air flow will pass through the filter surface of the circular tea sieve 5 and enter the next drying base 13 through the airflow holes 131. Such a design can reasonably induce the heat flow in the internal cavity and realize the drying of tea leaves on multiple circular tea sieves 5.

[0030] An insulation board 14 is arranged in the box body 1, and a heat pump 6 is arranged on the insulation board 14, and the heat pump 6 passes heat to the internal cavity through a pipe 61. Here, the heat pump 6 is used to generate heat and transfer the heat to the cavity of the roasted tea.

[0031] The bottom of the box 1 is provided with an insulation layer 15, and the insulation layer 15 and the box 1 form a recovery chamber 16. The insulation layer 15 is provided with a plurality of air holes 151. During the drying process, moisture and water mist condense and reach the recovery chamber 16 through the air holes 151, thereby ensuring the dryness of the drying space.

[0032] Working principle:

[0033] The tea leaves to be dried are placed on the circular tea sieve 5, and the circular tea sieve 5 is fixed on the circular turntable 4. At the same time, the control system of the tea dryer is started, the heat pump 6 is turned on, and the heat pump 6 starts to transport heat to the internal cavity, and the output temperature of the heat pump 6 can be automatically controlled; then, the control system of the tea dryer controls the start cycle of the motor 2 and the time of each start according to the output temperature, so as to realize automatic flipping.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, when the heat pump 6 starts working, the control system controls the start and stop of the four motors 2. Here is an example of a control method to deepen understanding: when the heat pump 6 works for a certain period of time at a certain output temperature, the control system automatically starts the four motors 2, and the motors 2 finally realize the reverse rotation of the first flip claw 31 and the second flip claw 32 to flip the tea leaves through the gears, and drive the circular tea sieve 5 to rotate to cooperate with the flipping of the tea leaves and evenly distribute the tea leaves; after flipping for a certain period of time, the control system controls the motor 2 to stop, and after a certain period of drying, the control system starts the motor 2 again to flip the tea leaves; the number of flips is controlled according to the drying conditions, and finally the tea leaves are dried.

[0035] The tea leaf turning mechanism designed by the utility model can not only turn the tea leaves thoroughly, but also ensure that the tea leaves are evenly distributed and of uniform thickness when turning, through the relative rotation of the two turning claws and the rotation of the circular tea sieve. The tea leaves finally dried are neither tender nor burnt, and the drying effect of all the tea leaves is consistent, thus meeting the quality requirements of tea leaf drying and improving the drying efficiency of the tea leaves.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
