Description

Technical Field

[0001] The utility model belongs to the field of tea turning and drying, in particular to a pretreatment device for cold extraction of tea powder. Background Art

[0002] Tea powder cold extraction is the use of an appropriate amount of low-temperature water to extract pre-treated tea leaves. Compared with the traditional hot extraction method, cold extraction can extract the effective ingredients in tea leaves at a lower temperature, retaining more natural aroma and nutrients.

[0003] Prior to this, the tea leaves need to be pre-treated, which includes cleaning, drying, etc. The purpose of drying is to reduce the water content of the tea leaves to extend the shelf life and improve the extraction efficiency. The degree of drying will affect the final tea flavor.

[0004] Tea leaves can be dried outdoors or in a heating box. When drying outdoors, the tea leaves are spread evenly using a dustpan or tray, and the tea leaves need to be turned over at regular intervals so that they can be evenly exposed to sunlight. However, if there are too many tea leaves to dry, turning them over manually takes a lot of time, and working for a long time outdoors under sunlight may also cause heatstroke to the workers. Utility Model Content

[0005] Technical problem to be solved: How to quickly turn the tea leaves over and dry them in the sun.

[0006] Technical solution: The utility model provides a pretreatment device for cold brewing of tea powder, including a tray assembly and a flip frame assembly. The tray assembly includes a rectangular frame, and support plates with the same specifications as those inside the rectangular frame can be placed at the top and bottom of the rectangular frame; at the same time, the top and bottom of the rectangular frame are also provided with limiting mechanisms for limiting the support plates from falling downward; the flip frame assembly includes a bottom plate, and the top of the bottom plate is symmetrically connected to two vertical frames, and the vertical frames are rotatably connected to a horizontal shaft fixed on the outside of the rectangular frame through bearings; in addition, one of the vertical frames is also provided with a driving mechanism for driving the shaft to flip.

[0007] Furthermore, the driving mechanism includes a mounting frame connected to the outside of one of the vertical frames, a motor is mounted on the mounting frame, an output shaft of the motor is connected to one of the rotating shafts, and the motor is driven by a cylindrical battery.

[0008] Furthermore, the limiting mechanism includes connecting holes which are symmetrically opened at the top and bottom ends of the rectangular frame, and a baffle is rotatably connected to the connecting hole via a bearing so that the baffle can rotate horizontally.

[0009] Furthermore, a storage groove matched with the support plate is provided on the front side of the bottom plate, so that one of the two support plates can be placed therein.

[0010] Furthermore, a receiving groove is provided in the middle of the top end of the base plate, which is connected to the receiving groove and communicates with the front side thereof; at the same time, a plurality of bosses arranged along its width direction are connected to the middle of the top end of the support plate, and these bosses are used as a leveraging structure. When the support plate is located in the receiving groove, these bosses are located in the receiving groove.

[0011] Furthermore, the mounting frame may be a C-shaped structure, and the motor is located in an opening of the C-shaped structure, with the front and back surfaces of the motor exposed to the outside for heat dissipation.

[0012] Technical effect: In the utility model, firstly, there are limiting mechanisms at the top and bottom of the rectangular frame to limit the support plate from falling downwards, that is, the support plate and the rectangular frame form a tray for spreading tea leaves through the action of the limiting mechanism. When the tea leaves need to be turned over for drying, another support plate is placed on the tea leaves to cover them, and then the limiting mechanism is used to block them. Then, the driving mechanism is used to drive the rotating shaft and the rectangular frame to flip over. After flipping over, the support plate and the rectangular frame originally placed on the tea leaves are re-formed into a tray, and the support plate flipped over can be removed and placed on the bottom plate. In this way, through such repeated operations, the tea leaves can be turned over and dried. Moreover, in this process, the staff only needs to perform simple operations of placing and removing the support plates, which is convenient and quick, and does not require them to work in the sun for a long time.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0020] The tea powder cold extraction pretreatment device provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a tray assembly and a turning frame assembly, wherein:

[0021] The tray assembly includes a rectangular frame 1, and a support plate 2 with the same specifications as the inner portion thereof can be placed at the top and bottom of the rectangular frame 1; at the same time, a limiting mechanism 3 for limiting the support plate 2 from falling downward is also provided at the top and bottom of the rectangular frame 1; Figure 3 As shown, the limiting mechanism 3 includes connecting holes 301 symmetrically opened at the top and bottom ends of the rectangular frame 1, and a baffle 303 is rotatably connected to the connecting hole 301 through a bearing so that the baffle 303 can rotate horizontally. In the initial state, one end of the baffle 303 is flush with the outer side of the rectangular frame 1, and the other end protrudes to the bottom of the support plate 2.

[0022] The flip frame assembly includes a bottom plate 4, the top of which is symmetrically connected to two vertical frames 5, and the vertical frames 5 are rotatably connected to a horizontal shaft 6 fixed to the outside of the rectangular frame 1 through a bearing; in addition, a driving mechanism 7 for driving the shaft 6 to flip is also provided on one of the vertical frames 5. Figure 2 As shown, the driving mechanism 7 includes a mounting frame 701 connected to the outside of one of the vertical frames 5, a motor 702 is mounted on the mounting frame 701, an output shaft of the motor 702 is connected to one of the rotating shafts 302, and the motor 702 is driven by a cylindrical battery.

[0023] To summarize the above process: first, there are two support plates 2, one of which is limited to the bottom end of the rectangular frame 1 by the baffle 303, and forms a tray with the rectangular frame 1 for spreading tea leaves for drying, and the other is placed on the bottom plate 4 for standby. When the tea leaves need to be turned over for drying, the standby support plate 2 is placed on the tea leaves, and then the baffle 303 is used to block it, and then the driving mechanism 7 is used to drive the rotating shaft 302 and the rectangular frame 1 to rotate 180°. Through this rotation process, the tea leaves are turned over, and at this time, the upper baffle 303 is rotated, and then the upper support plate 2 is taken off and placed on the bottom plate 4.

[0024] Because the whole device is outdoors, the spare support plate 2 placed on the bottom plate 4 may be contaminated with more dust, so that the dust is mixed with the tea leaves. Therefore, in order to avoid this situation, Figure 4As shown, the front of the bottom plate 4 is provided with a receiving groove 8 adapted to the support plate 2, so that one of the two support plates 2 can be placed therein. Further, in order to facilitate the removal of the support plate 2 from the receiving groove 8, on the one hand, a receiving groove 10 communicating with the receiving groove 8 and communicating with the front thereof is provided at the middle of the top of the bottom plate 4; on the other hand, a plurality of convex columns 9 arranged along the width direction are connected to the middle of the top of the support plate 2, and these convex columns 9 are used as a lever structure. When the support plate 2 is located in the receiving groove 8, these convex columns 9 are located in the receiving groove 10. In this way, the support plate 2 can be pulled out by using the convex columns 9 as a lever structure.

[0025] It is worth mentioning that, taking into account the protection and heat dissipation of the motor 702, the mounting bracket 701 can be a C-shaped structure, and the motor 702 is located in the opening of the C-shaped structure, so that most of the motor 702 is protected, but its front and back faces are exposed to the outside for heat dissipation.
