Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a pre-processing device for extracting tea aroma. Background Technology

[0002] Aroma extraction of tea is a technique that uses physical or chemical methods to separate and concentrate aroma components from tea leaves, aiming to preserve the unique aromatic qualities of tea. Commonly used extraction methods include steam distillation and solvent extraction. Steam distillation involves heating the tea leaves, causing the aroma components to volatilize with the steam, which is then collected by condensation; this method is suitable for extracting highly volatile aroma substances. Solvent extraction utilizes organic solvents to dissolve the aroma components in the tea leaves, and then evaporates the solvent to obtain a concentrated aroma essence.

[0003] Before extracting the aroma of tea, the raw tea leaves need to be pre-treated by screening and purification to remove fine particles, dust, and other impurities. This includes removing tea residue, stems, and non-compliant leaves to prevent these impurities from affecting the purity and concentration of aroma components during extraction. Current technology typically uses pre-treatment devices with sieves or screens for screening and purification. However, during screening, the tea leaves have low mobility and tend to accumulate, making it difficult to fully remove impurities and affecting the overall purification effect. Furthermore, the unloading process after treatment is cumbersome and inconvenient, as some tea leaves easily adhere to the sieve or screen, clogging the sieve holes and requiring cleaning, thus impacting overall processing efficiency.

[0004] Therefore, it is necessary to provide a pre-processing device for extracting tea aroma to solve the above-mentioned technical problems. Utility Model Content

A second motor is fixed on the outer wall of the closed end of the processing cylinder, and a discharge assembly for removing material from inside the sieve cylinder is driven and connected to the second motor.

[0007] As a further embodiment of this utility model, the air outlet component includes an air blowing rod disposed at the center of the inside of the sieve cylinder. The air blowing rod has a cavity a inside, and an air blowing hole a communicating with the cavity a is disposed on the side of the air blowing rod.

The sliding rod slides through the closed end sidewall of the processing cylinder, and an air inlet pipe is fixed inside the end of the sliding rod away from the pusher plate.

[0010] As a further embodiment of this utility model, a rack plate arranged along the length of the slide rod is fixed on the outer wall of the slide rod, and a gear a that meshes with the rack plate is fixed on the output end of the second motor.

[0011] As a further embodiment of this utility model, the side of the pusher plate is provided with an air blowing hole b communicating with the cavity b. The air blowing hole b is inclined toward the inner wall of the screen cylinder, and multiple air blowing holes b are provided and the multiple air blowing holes b are distributed in a ring.

[0012] As a further embodiment of this utility model, the bottom end of the processing cylinder is fixed with two symmetrically distributed supports, the bottom ends of the two supports are jointly fixed with a base plate, a cover plate a is hinged to the open end of the processing cylinder, and a handle is fixed to the outer side wall of the cover plate a.

[0013] As a further embodiment of this utility model, the bottom of the processing cylinder is provided with a discharge port, and a cover plate b is hinged inside the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Please see Figure 1-7 This utility model provides a pre-processing device for extracting tea aroma, including a processing cylinder 3. One end of the processing cylinder 3 is open, and a sieve cylinder 13 is rotatably connected inside the processing cylinder 3. A toothed ring 12 is fixed on the outer wall of the sieve cylinder 13. A first motor 4 is fixed on the outer wall of the processing cylinder 3. A gear b5, meshing with the toothed ring 12, is fixed on the output end of the first motor 4. An air outlet component 1 for blowing air is provided inside the sieve cylinder 13. A second motor 10 is fixed on the outer wall of the closed end of the processing cylinder 3. A discharge component 2 for removing material from inside the sieve cylinder 13 is driven and connected to the second motor 10. In use, the cover plate a6 is opened, the tea raw material is put into the sieve cylinder 13, and the first motor 4 is started. The output end of the first motor 4 drives the gear b5 automatically, thereby driving the sieve cylinder 13 to rotate through the cooperation of the gear b5 and the toothed ring 12, so that the tea raw material inside the sieve cylinder 13 continuously tumbles, making the tea aroma extracted. Particulate impurities and small tea residues mixed in with the raw tea leaves continuously fall through the sieve holes on the sieve cylinder 13, thereby screening and purifying the raw tea leaves, removing particulate impurities and small tea residues, and pre-treating the tea leaves to facilitate further processing, improving the efficiency and quality of tea aroma extraction. During this process, the air outlet component 1 sprays the airflow evenly and finely onto the raw tea leaves, effectively increasing the movement of the raw tea leaves, greatly reducing the accumulation of the raw tea leaves, and allowing impurities and tea residues in the raw tea leaves to be fully discharged, further improving the thoroughness of tea leaf impurity removal and improving the tea leaf impurity removal efficiency. After the tea leaf impurity removal process is completed, the second motor 10 is started to rotate, which drives the discharge component 2 to work, thereby assisting in pushing and discharging the tea leaves in the sieve cylinder 13, effectively improving the material handling efficiency and the overall processing efficiency.

[0030] Further as Figure 3 , Figure 4 and Figure 7As shown, it is worth noting that the air outlet assembly 1 includes an air blowing rod 101 located at the center of the inside of the sieve cylinder 13. The air blowing rod 101 has a cavity a103 inside, and air blowing holes a102 communicating with the cavity a103 are opened on the side of the air blowing rod 101. There are multiple air blowing holes a102, and the multiple air blowing holes a102 are evenly distributed. In specific operation, airflow is input into the cavity a103, and the airflow is sprayed into the tea raw material in a uniform and refined manner through the multiple air blowing holes a102. Through the blowing action of the airflow on the tea, the movement of the tea raw material is effectively increased, the accumulation of the tea raw material is greatly reduced, and the impurities and tea residues in the tea raw material can be fully discharged, further improving the adequacy of tea raw material impurity removal and improving the tea impurity removal efficiency.

[0031] Further as Figure 2 , Figure 4 and Figure 7 As shown, it is worth noting that the discharge assembly 2 includes a pusher plate 204 that can move inside the screen cylinder 13. An air blower 101 is fixed at the center of the pusher plate 204. The pusher plate 204 has a cavity b104 communicating with cavity a103. A slide rod 201 communicating with cavity b104 is fixed at the center of the pusher plate 204. A cavity c105 communicating with cavity b104 is opened inside the slide rod 201. The slide rod 201 slides through the closed end sidewall of the processing cylinder 3. An air inlet pipe 9 is fixed inside the end of the slide rod 201 away from the pusher plate 204. A rack plate 202 arranged along the length of the slide rod 201 is fixed on the outer sidewall of the slide rod 201. A gear a203 meshing with the rack plate 202 is fixed on the output end of the second motor 10. After the tea raw material impurity removal process is completed, the second motor 10 is started to rotate, passing through the... The output of the second motor 10 drives the gear a203 to rotate, which in turn drives the slide bar 201 to move through the gear a203 and the rack plate 202. The slide bar 201 drives the pusher plate 204 to move inside the screen cylinder 13 towards the opening of the screen cylinder 13. The pusher plate 204 pushes the processed tea raw materials in the screen cylinder 13 and discharges them through the opening of the screen cylinder 13, effectively improving the material handling efficiency and the overall processing efficiency. At the same time, the pusher plate 204 drives the air blowing rod 101 to move out of the screen cylinder 13, making it convenient to clean and maintain the air blowing rod 101. The air inlet pipe 9 is connected to an air pump, which delivers airflow to the slide bar 201 and into the cavity a103 of the air blowing rod 101 through the slide bar 201 and the pusher plate 204. The air is then blown into the interior of the tea raw materials in a uniform and fine manner through multiple air blowing holes a102.

[0032] Further as Figure 4 and Figure 5As shown, it is worth noting that the pusher plate 204 has air holes b205 on its side that communicate with the cavity b104. The air holes b205 are inclined towards the inner wall of the screen cylinder 13, and there are multiple air holes b205 arranged in a ring. In actual operation, the airflow inside the pusher plate 204 is evenly sprayed onto the inner wall of the screen cylinder 13 through the multiple air holes b205. This airflow blows down and cleans some of the tea leaves adhering to the inner wall of the screen cylinder 13, thus cleaning the inner wall of the screen cylinder 13. This eliminates the need to clean the inner wall and screen holes of the screen cylinder 13, and improves the fullness of material handling.

[0033] This solution includes the following working process: Open the cover plate a6, insert the tea leaves into the sieve cylinder 13, start the first motor 4, and the output of the first motor 4 drives the gear b5 automatically. The gear b5, in conjunction with the gear ring 12, rotates the sieve cylinder 13, causing the tea leaves inside to tumble continuously. This allows particulate impurities and smaller tea residues mixed in with the tea leaves to fall through the sieve holes on the sieve cylinder 13, thus purifying the tea leaves and removing particulate impurities and smaller tea residues. During this process, airflow is delivered to the slide rod 201 through the air inlet pipe 9, and then input into the cavity a103 of the blowing rod 101 through cavities c105 and b104. The air is then evenly and finely blown into the interior of the tea leaves through multiple blowing holes a102, thus agitating the tea leaves. This process effectively increases the movement of tea raw materials, greatly reducing their accumulation and allowing impurities and residues to be fully discharged. After the tea raw materials are cleaned, the second motor 10 is started to rotate. The output of the second motor 10 drives the gear a203 to rotate, which in turn drives the slide bar 201 to move through the gear a203 and the rack plate 202. The slide bar 201 drives the pusher plate 204 to move towards the opening of the screen cylinder 13 inside the screen cylinder 13. The pusher plate 204 pushes the processed tea raw materials in the screen cylinder 13 and discharges them through the opening of the screen cylinder 13. At the same time, the air inlet pipe 9 continues to input gas, and the airflow inside the pusher plate 204 is evenly sprayed onto the inner wall of the screen cylinder 13 through multiple air blowing holes b205. This airflow blows off and cleans some of the tea raw materials adhering to the inner wall of the screen cylinder 13.

[0034] Further as Figure 1 As shown, it is worth noting that two symmetrically distributed supports 7 are fixed at the bottom of the processing cylinder 3, and a base plate 8 is fixed at the bottom of the two supports 7. A cover plate a6 is hinged to the open end of the processing cylinder 3, and a handle is fixed on the outer wall of the cover plate a6. In actual operation, the open end of the processing cylinder 3 is opened and closed by the cover plate a6.

[0035] Further as Figure 6 As shown, it is worth noting that the bottom of the processing cylinder 3 is provided with a discharge port 14, and a cover plate b15 is hinged inside the discharge port 14. In actual operation, the particulate impurities and residues screened out by the screen cylinder 13 fall to the bottom of the processing cylinder 3, and the impurities are discharged through the discharge port 14 by opening the cover plate b15.

[0036] In summary: By uniformly and finely spraying the airflow into the tea raw materials through the air outlet component 1, the movement of the tea raw materials is effectively increased, the accumulation of tea raw materials is greatly reduced, and impurities and tea residues in the tea raw materials can be fully discharged, further improving the thoroughness of tea raw material impurity removal and improving the tea impurity removal efficiency; after the tea raw material impurity removal process is completed, the tea raw materials in the screen cylinder 13 are assisted to be pushed out through the discharge component 2, which effectively improves the material collection efficiency and the overall processing efficiency.

[0037] The first motor 4 and the second motor 10 can be purchased from the market. The drive motor is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it will not be repeated in the specification.
