Description

Technical Field

[0001] The utility model relates to the field of Pu'er tea drying, in particular to a drying structure for Pu'er tea after fermentation. Background Art

[0002] Piling is a fermentation process in the production of Pu'er tea, and it is also the key point to determine the quality of ripe tea. It refers to piling the sun-dried green tea to a certain height, sprinkling water on it, and covering it with linen to promote the action of Pu'er tea enzymes. It is fermented under the action of moisture and heat for about 24 hours. After the Pu'er tea is converted to a certain degree, it is spread out to dry. The above-mentioned piling process can also be completed by an automated or semi-automated piling production line. The production line can reduce manual participation, improve work efficiency, and can also more accurately control temperature and humidity.

[0003] In the Pu'er tea pile fermentation process, the fermented Pu'er tea needs to be dried before the Pu'er tea is discharged, so that the moisture content of the material naturally drops to 15%. The equipment for drying Pu'er tea is generally called a Pu'er tea drying device. The existing Pu'er tea drying device generally includes a hot drying component and a conveying component, wherein the conveying component generally uses a conveyor belt. The conveyor belt and the hot drying component can simultaneously complete the conveying and drying of Pu'er tea. However, Pu'er tea needs to be spread on the conveyor belt during transportation. At this time, the dried Pu'er tea is unevenly heated, and the internal Pu'er tea cannot be fully hot-dried. Multiple drying processes are required to evenly dry the Pu'er tea, which increases working hours and reduces efficiency. Moreover, since the Pu'er tea is wet when it is transported to the conveyor belt, and the wet Pu'er tea at the bottom will be under pressure from the upper Pu'er tea, the Pu'er tea in contact with the conveyor belt is easy to adhere to the conveyor belt after heating, which is inconvenient to clean. In order to solve the above problems, a drying structure for Pu'er tea after fermentation is proposed. Utility Model Content

[0025] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0028] For example 1, please refer to Figures 1 to 3 The structure shown in the embodiment of the utility model is a drying structure for Pu'er tea after fermentation, comprising:

[0029] A receiving tube 1 with openings at both ends;

[0030] The drying component includes a hot dryer 4 and a feeding mechanism 5. The feeding mechanism 5 includes a feeding cylinder 501. The feeding cylinder 501 is arranged in the receiving cylinder 1. Filters 502 are arranged on the cylinder wall along the length direction of the feeding cylinder 501 at intervals. A plurality of lifting members are arranged in a circular array on the inner wall of the feeding cylinder 501. The lifting members include a plurality of lifting plates 503 arranged at intervals along the length direction of the feeding cylinder. The inner wall of the feeding cylinder 501 is provided with lifting plates 503. A cleaning member 504 is provided inside the feeding barrel 501 along its length. The cleaning member 504 includes an integrated barrel 5041. A connecting rod 5042 is provided on the side wall of the integrated barrel 5041 along its circumference. A scraping member is provided at one end of the connecting rod 5042 away from the integrated barrel 5041. The scraping member is in contact with the wall surface of the lifting plate 503 and the inner wall of the feeding barrel 501 to clean tea leaves adhered to the wall surface of the lifting plate 503 and the inner wall of the feeding barrel 501.

[0031] The driving assembly is used to drive the feeding barrel 501 to rotate.

[0032] In this embodiment, the receiving tube 1 is a long tube with openings at both ends and a hollow interior, and the outer diameter of the feeding tube 501 is smaller than the inner diameter of the receiving tube 1 .

[0033] Furthermore, the driving assembly includes a driving source 2, a transmission assembly and a rotating assembly. The driving source 2 is arranged on the outer wall of the receiving cylinder 1. The transmission assembly includes gear 1 3 and gear 2 6. Gear 1 3 is detachably connected to the output end of the driving source 2, and the two can be detachably connected by pin connection or key connection. The feeding cylinder 501 passes through gear 2 6, and the feeding cylinder 501 is detachably connected to the gear 2 6. The rotating assembly includes a swivel 7 and a supporting member. The supporting member includes two rotating tables 8 placed opposite to each other. A rotating cylinder 9 is rotatably installed on the rotating table 8. The feeding cylinder 501 passes through the swivel 7, and the feeding cylinder 501 is detachably connected to the swivel 7. The swivel 7 is mounted on the two rotating tables 8.

[0034] In this embodiment, the driving source 2 can be a motor, and gear 2 6 is located in the receiving cylinder 1. An arc-shaped opening is provided on the wall of the receiving cylinder 1. Gear 1 3 passes through the arc-shaped opening and engages with gear 2 6. When the driving source 2 outputs torque, it will drive gear 1 3 to rotate, thereby driving gear 2 6 to rotate, so that the feeding cylinder 501 has a tendency to rotate. Since the rotating ring 7 is mounted on the rotatable rotating cylinder 9, the rotation of the feeding cylinder 501 with a rotation tendency is not restricted. It should be noted that the number of supporting parts is several, and the several supporting parts are relatively arranged inside the receiving cylinder 1.

[0035] Furthermore, the heat drying machine 4 is fixedly installed on the inner wall of the receiving cylinder 1 , and the heat drying machine 4 is used to dry the Pu'er tea inside the feeding cylinder 501 .

[0036] See also Figures 3 to 6 In the structure shown, further, a connecting plate 5044 is provided on the integrated cylinder 5041 , and the connecting plate 5044 is detachably connected to the feeding cylinder 501 .

[0037] In this embodiment, the connecting plate 5044 is bolted to the feeding barrel 501, and a threaded hole 1 is provided on the connecting plate 5044. A threaded hole 2 opposite to the connecting hole 1 is provided on the side wall of the feeding barrel 501. By screwing the bolt into the threaded hole 1 and the threaded hole 2 and unscrewing the bolt from the two, the integrated barrel 5041 can be installed on the side of the feeding barrel 501, and the integrated barrel 5041 can also be removed from the feeding barrel 501.

[0038] Furthermore, a sliding bar 5043 is formed on the connecting rod 5042 and the integrated cylinder 5041 , and a sliding groove (not shown in the figure) matching the sliding bar 5043 is opened in the feeding cylinder 501 .

[0039] Furthermore, the scraping member includes a scraper 5045 and a scraper 2 5046 arranged on the scraper 1 5045. The scraper 1 5045 is fixedly connected to one end of the connecting rod 5042. The scraper 1 5045 is in contact with the inner wall of the feeding barrel 501. The wall surface of the scraper 2 5046 is in contact with the wall surface of the lifting plate 503 located near the opening of the feeding barrel 501.

[0040] In this embodiment, when the integrated cylinder 5041 is not removed from the feeding cylinder 501, the wall surface of the hanging plate 2 5046 is in contact with the wall surface of the lifting plate 503 located at the opening of the feeding cylinder 501. There are several lifting plates 503, which are spaced from one opening of the feeding cylinder 501 to another along the length direction of the feeding cylinder 501. The reason why the lifting parts use several lifting plates 503 spaced apart instead of a whole plate is to allow the Pu'er tea to flow more fully when the feeding cylinder 501 rotates, so that it can be dried more fully.

[0041] Furthermore, there are a plurality of connecting rods 5042 , and the gap between two adjacent scraper plates 5045 is greater than the width of the lifting plate 503 .

[0042] In this embodiment, when the integrated cylinder 5041 is removed from the feeding cylinder 501, the integrated cylinder 5041 is pulled back and forth so that the scraping member can move along the length direction of the feeding cylinder 501, and the scraper 5045 originally in contact with the surface of the feeding cylinder 501 will move with the movement of the integrated cylinder 5041, thereby pushing the Pu'er tea to the opening of the feeding cylinder 501 for collection, and then, continue to pull the integrated cylinder 5041 to scrape off the remaining Pu'er tea attached to the wall of the feeding cylinder 501 and the lifting plate 503, and the staff will then collect the Pu'er tea here, thereby completely collecting the Pu'er tea inside the feeding cylinder 501.

[0043] See also Figure 1 In the structure shown, the drying mechanism further includes a sealing cover 10 , which is threadedly connected to the side wall of the feeding barrel 501 .

[0044] Please refer to all the attached drawings for the specific method of using the drying structure for Pu'er tea after fermentation: start the hot drying machine 4 to increase the temperature inside the receiving cylinder 1, start the driving source 2, and drive the feeding cylinder 501 to rotate. The fermented Pu'er tea is transported from one end opening of the feeding cylinder 501 to the inside of the feeding cylinder 501. As the feeding cylinder 501 rotates, the Pu'er tea rotates accordingly. Since the fermented Pu'er tea is relatively moist, it has a certain weight, so some Pu'er tea will accumulate in the lower part of the feeding cylinder 501, which cannot be fully dried. A part of the Pu'er tea can be extracted by the lifting plate 503, so that the tea at the bottom can be dried. When the feeding barrel 501 rotates to the highest point, the Pu'er tea will not accumulate due to its own weight, so that the Pu'er tea can be distributed more evenly in the feeding barrel 501, and the Pu'er tea can be dried more fully. After drying, open the cover 10, unscrew the bolts connecting the integrated barrel 5041 and the feeding barrel 501, pull the integrated barrel 5041, and as the scraper 1 5045 and the scraper 2 5046 move, the Pu'er tea is pushed out from the inside of the feeding barrel 501. Move the integrated barrel 5041 back and forth many times to scrape off the Pu'er tea attached to the inner wall of the feeding barrel 501 and the lifting plate 503, and push it to the opening of the feeding barrel 501 for collection.
