Description

Technical Field

[0001] This utility model relates to the field of tea fixation technology, specifically a tea fixation device. Background Technology

[0002] Currently, tea, commonly known as tea, generally includes the leaves and buds of the tea plant. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages are one of the world's three major beverages.

[0003] Among them, the fixation process involves using high temperatures to destroy and deactivate the oxidase activity in fresh tea leaves, inhibiting the enzymatic oxidation of tea polyphenols and other substances in the fresh leaves, evaporating some of the moisture in the fresh leaves, making the tea leaves softer and easier to roll and shape, while also removing the grassy smell and promoting the formation of a good aroma. Fixation is a key process in the formation of the shape and quality of green tea and other teas.

[0004] Existing tea processing techniques typically involve placing tea leaves inside a rotating furnace, where they continuously contact the furnace walls to achieve the desired processing effect. However, this method leads to over-drying of the tea leaves due to prolonged contact with the furnace walls. As the tea leaves continue to dry, they become very brittle. Furthermore, the rotating furnace constantly drops the tea leaves from a high position to a low position, causing them to break. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide a tea fixing device that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tea fixing device, comprising a base, wherein sliding seats are fixedly installed on both sides of the top of the base, and sliding rings are rotatably installed inside the two sets of sliding seats, and drying cylinders are fixedly installed on the inner walls of the two sets of sliding rings, and a protective mechanism is installed inside the drying cylinder;

[0007] The protective mechanism includes multiple sets of equally spaced spiral blades fixedly installed on the inner wall of the drying cylinder, brackets fixedly installed on both sides of the inner wall of the drying cylinder, bearings rotatably installed in the middle of the two sets of brackets, rotating rods rotatably installed on the shafts of the two sets of bearings, a receiving cylinder fixedly installed between the two sets of rotating rods, and multiple sets of equally spaced receiving grooves opened on the outer wall of the receiving cylinder.

[0008] As an optional solution to the technical solution of this application, the multiple sets of receiving grooves correspond to each set of spiral blades, and each set of spiral blades is arc-shaped.

[0009] As an optional solution to the technical solution of this application, a battery replacement box is fixedly installed on the side wall of the drying cylinder, and a storage battery is detachably installed on the inner wall of the battery replacement box. A heating ring is fixedly installed on the storage battery through wires, and the heating ring is distributed on the inner wall of the drying cylinder cavity, which can heat the inner wall of the drying cylinder.

[0010] As an optional solution to the technical solution of this application, a guide cover is connected and installed in the middle of one side port of the drying cylinder, and a discharge cover is connected and installed in the other side port of the drying cylinder. A second sprocket is fixedly installed on the outer wall of the discharge cover, which can drive the drying cylinder to rotate.

[0011] As an optional solution to the technical solution of this application, a third sprocket is fixedly installed at the other end of the rotating rod located on one side. The third sprocket is distributed inside the discharge hood and can drive the receiving cylinder to rotate.

[0012] As an optional solution to the technical solution of this application, a motor is fixedly installed on one side of the bottom of the base. The motor drive output end is connected to the transmission shaft, and two sets of equidistant first sprockets are fixedly installed on the other end of the transmission shaft. The two sets of first sprockets are respectively connected to the second sprocket and the third sprocket through two sets of chains, which can drive the second sprocket and the third sprocket to rotate synchronously.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The technical solution of this application involves a drying drum continuously rotating a large amount of tea leaves. The tea leaves move along the spiral blades to the top of the drying drum's inner cavity and then fall to the bottom. Simultaneously, this pushes the receiving drum inside the protective mechanism, causing it to rotate continuously between two sets of supports. When the tea leaves fall from the top of the drying drum's inner cavity, the receiving groove on the outer wall of the receiving drum will preferentially receive a large amount of falling tea leaves. As the receiving drum rotates, it can guide the received tea leaves to the bottom of the drying drum's inner cavity, greatly reducing the height of the falling tea leaves and the contact time with the inner wall of the drying drum. This not only effectively avoids the tea leaves from prolonged contact with the inner wall of the drying drum, preventing over-drying, but also effectively reduces the height of the falling tea leaves, preventing damage from collisions with the inner wall of the drying drum and affecting the quality of the tea leaves.

[0015] 2. The technical solution of this application has two sets of equidistant first sprockets installed on the motor drive shaft. The two sets of first sprockets are respectively connected to the second sprocket and the third sprocket through two sets of chains. When the operator drives the motor, the two sets of first sprockets on the drive shaft can be driven to rotate synchronously. Since the two sets of first sprockets are respectively connected to the second sprocket and the third sprocket through chains, when the drying cylinder rotates on the top of the two sets of slides, the receiving cylinder rotates synchronously on the inner wall of the drying cylinder, thus protecting the tea leaves dried inside the drying cylinder.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a tea fixing device, including a base 1, with slide seats 11 fixedly installed on both sides of the top of the base 1, and sliding rings 12 rotatably installed inside the two sets of slide seats 11, and drying cylinders 13 fixedly installed on the inner walls of the two sets of sliding rings 12, with a protective mechanism installed inside the drying cylinder 13.

[0023] The protective mechanism includes multiple sets of equally spaced spiral blades 2 fixedly installed on the inner wall of the drying cylinder 13, brackets 21 fixedly installed on both sides of the inner wall of the drying cylinder 13, bearings 22 rotatably installed in the middle of the two sets of brackets 21, rotating rods 23 rotatably installed in the middle of the two sets of bearings 22, a receiving cylinder 24 fixedly installed between the two sets of rotating rods 23, and multiple sets of equally spaced receiving grooves 25 opened on the outer wall of the receiving cylinder 24. The multiple sets of receiving grooves 25 correspond to each set of spiral blades 2, and each set of spiral blades 2 is arc-shaped.

[0024] In this technical solution, as the drying cylinder 13 continuously rotates a large amount of tea leaves, the tea leaves move along the spiral blades 2 to the top of the inner cavity of the drying cylinder 13 and fall to the bottom of the inner cavity. At the same time, it pushes the receiving cylinder 24 in the protective mechanism, causing the receiving cylinder 24 to rotate continuously between the two sets of supports 21. When the tea leaves fall from the top of the inner cavity of the drying cylinder 13, the receiving groove 25 on the outer wall of the receiving cylinder 24 will preferentially receive a large amount of falling tea leaves. As the receiving cylinder 24 rotates, it can guide the received tea leaves to the bottom of the inner cavity of the drying cylinder 13, greatly reducing the height of the falling tea leaves and the contact time with the inner wall of the drying cylinder 13. This not only effectively avoids the tea leaves from being in contact with the inner wall of the drying cylinder 13 for a long time, causing the tea leaves to be over-dried, but also effectively reduces the height of the falling tea leaves and avoids damage to the tea leaves from collision with the inner wall of the drying cylinder 13, thus affecting the quality of the tea leaves.

[0025] In some technical solutions, a guide cover is connected and installed in the middle of one side port of the drying cylinder 13, and a discharge cover 32 is connected and installed in the other side port of the drying cylinder 13. A second sprocket 33 is fixedly installed on the outer wall of the discharge cover 32, which can drive the drying cylinder 13 to rotate. A third sprocket 34 is fixedly installed at the other end of one side rotating rod 23. The third sprocket 34 is distributed inside the discharge cover 32 and can drive the receiving cylinder 24 to rotate. A motor 3 is fixedly installed on one side of the bottom of the base 1. The drive output end of the motor 3 is connected to the transmission shaft, and two sets of equidistant first sprockets 31 are fixedly installed at the other end of the transmission shaft. The two sets of first sprockets 31 are respectively connected to the second sprocket 33 and the third sprocket 34 through two sets of chains 35, which can drive the second sprocket 33 and the third sprocket 34 to rotate synchronously.

[0026] In this technical solution, two sets of equidistant first sprockets 31 are installed on the drive shaft of the motor 3. The two sets of first sprockets 31 are respectively connected to the second sprocket 33 and the third sprocket 34 through two sets of chains 35. When the operator drives the motor 3, the two sets of first sprockets 31 on the drive shaft can be driven to rotate synchronously. Since the two sets of first sprockets 31 are connected to the second sprocket 33 and the third sprocket 34 through chains 35 respectively, when the drying cylinder 13 rotates on the top of the two sets of slides 11, the receiving cylinder 24 rotates synchronously on the inner wall of the drying cylinder 13, thus protecting the tea leaves dried inside the drying cylinder 13.

[0027] In some technical solutions, slide blocks 11 are fixedly installed on both sides of the top of the base 1, and slip rings 12 are rotatably installed inside the two sets of slide blocks 11. The two sets of slip rings 12 are distributed on both sides of the drying cylinder 13.

[0028] In this technical solution, when the drive motor 3 is used, it can synchronously drive the two sets of first sprockets 31 on the transmission shaft to rotate, and in conjunction with the two sets of chains 35, synchronously drive the drying cylinder 13 and the receiving cylinder 24 to rotate. In conjunction with the internal rotating installation of slip rings 12 in the two sets of slide blocks 11, the drying cylinder 13 is effectively supported and limited.

[0029] In some technical solutions, a battery replacement box 14 is fixedly installed on the side wall of the drying cylinder 13. A storage battery is detachably installed on the inner wall of the battery replacement box 14. A heating ring 15 is fixedly installed on the storage battery through wires. The heating ring 15 is distributed on the inner wall of the cavity of the drying cylinder 13 and can heat the inner wall of the drying cylinder 13.

[0030] In this technical solution, the battery installed inside the battery replacement box 14 can provide power to the heating ring 15 inside the drying cylinder 13 to heat the inner wall of the drying cylinder 13. The battery replacement box 14 has the characteristics of quick disassembly and quick installation, which makes it convenient for the operator to replace the battery.

[0031] When using a tea fixing device, it should be noted that this utility model is a tea fixing device, and all components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] In use, the moist tea leaves are first guided into the drying cylinder 13 through the guide hood. The power is then turned on, and the heating ring 15 continuously heats the inner wall of the drying cylinder 13. Multiple sets of equidistantly distributed spiral blades 2 are installed on the inner wall of the drying cylinder 13, allowing the tea leaves to continuously roll and contact the high-temperature inner wall, effectively removing moisture and achieving a good blanching effect. As the drying cylinder 13 continuously rolls with a large amount of tea leaves, the leaves move along the spiral blades 2 to the top of the inner cavity of the drying cylinder 13 and fall to the bottom. Simultaneously, this pushes the receiving cylinder 24 inside the protective mechanism, causing it to rotate continuously between two sets of supports 21. When the tea leaves fall from the top of the inner cavity of the drying cylinder 13, the receiving groove 25 on the outer wall of the receiving cylinder 24 preferentially receives the large amount of falling tea leaves. As the receiving cylinder 24 rotates, the received tea leaves are guided into the drying chamber. The bottom of the inner cavity of the drying cylinder 13 significantly reduces the height at which the tea leaves fall and the contact time with the inner wall of the drying cylinder 13. This not only effectively prevents the tea leaves from being in contact with the inner wall of the drying cylinder 13 for a long time, thus avoiding over-drying, but also effectively reduces the height at which the tea leaves fall, preventing damage from collisions with the inner wall of the drying cylinder 13 and affecting the quality of the tea leaves. At the same time, two sets of equidistant first sprockets 31 are installed on the drive shaft of the motor 3, and the two sets of first sprockets 31 are respectively connected to the second sprocket 33 and the third sprocket 34 through two sets of chains 35. When the operator drives the motor 3, the two sets of first sprockets 31 on the drive shaft can be driven to rotate synchronously. Since the two sets of first sprockets 31 are connected to the second sprocket 33 and the third sprocket 34 through chains 35 respectively, when the drying cylinder 13 rotates on top of the two sets of slides 11, the receiving cylinder 24 rotates synchronously on the inner wall of the drying cylinder 13, protecting the tea leaves drying inside the drying cylinder 13.
