Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a screening and drying device for tea processing. Background Technology

[0002] Tea processing refers to the process of transforming freshly picked leaves into a drinkable tea product through a series of treatments. The main functions of tea processing include:

[0003] Improving Tea Quality and Taste: Tea processing removes impurities and moisture from tea leaves, making them purer and drier, which is beneficial for preservation and transportation. Through processes such as withering, fixation, rolling, and fermentation, the chemical composition and physical properties of tea leaves change, resulting in different aromas, flavors, and liquor colors to satisfy diverse consumer preferences. Increasing Tea's Added Value: Tea processing can transform ordinary tea leaves into various specialty teas, such as black tea, green tea, dark tea, white tea, and oolong tea. It can also combine tea with other ingredients or medicinal herbs to create various functional teas, such as flower and fruit teas, health teas, and weight-loss teas, thereby increasing the added value and market competitiveness of tea. Extending Tea's Shelf Life: Tea processing can inhibit the activity of enzymes and the growth of microorganisms in tea leaves, reducing the oxidation and decomposition of nutrients, thus extending the shelf life of tea. Through packaging and storage measures, it can also prevent tea from being affected by factors such as light, oxygen, moisture, and odors, maintaining the quality and flavor of the tea.

[0004] However, in practical applications of existing technologies, in the traditional tea processing process, screening and drying are two separate steps, which usually require manual or mechanical equipment to complete separately. This not only increases processing time and costs, but may also damage the quality of tea due to improper operation. Utility Model Content

[0005] The purpose of this utility model is to provide a screening and drying device for tea processing, in order to solve the problem mentioned in the background art that in the traditional tea processing process, screening and drying are two independent steps, which usually need to be completed manually or by mechanical equipment. This not only increases the processing time and cost, but may also lead to damage to the quality of tea due to improper operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a main support frame, with a through hole in the middle of the upper end of the main support frame. A support spring is fixedly installed on the upper end of the main support frame, and a screening cylinder is fixedly installed on the top of the support spring. A waste discharge cylinder is fixedly connected to the lower end of the screening cylinder. Vibration motors are fixedly installed on both sides of the screening cylinder. A limiting ring is fixedly installed on the inner wall of the screening cylinder. A positioning groove is provided on the upper end of the limiting ring. A sieve ring is movably connected to the upper end of the limiting ring. A positioning boss is provided on the lower end of the sieve ring. A sieve screen for screening tea leaves is fixedly installed on the inner wall of the sieve ring. A collection box is movably connected to the inner side of the lower end of the main support frame.

[0007] A support platform is fixedly installed on the upper end of the main support frame. An electric telescopic rod is fixedly installed through the upper end of the support platform. An installation ring is fixedly installed on the telescopic part of the lower end of the electric telescopic rod. Limiting slide rods are fixedly installed on both sides of the upper end of the installation ring. An electric heating tube for drying tea leaves is fixedly installed inside the installation ring. An installation plate is fixedly installed at the lower end of the installation ring. An exhaust fan is fixedly installed through the lower end of the installation plate.

[0008] Preferably, there are several support springs, which are symmetrically distributed sequentially at the upper end of the main support frame.

[0009] Preferably, the lower end of the screening cylinder passes through the interior of the through hole, and the lower end of the screening cylinder is conical.

[0010] Preferably, there are two vibration motors, which are symmetrically distributed on both sides of the screening cylinder.

[0011] Preferably, the positioning boss is movably connected to the inner wall of the positioning groove, and handles for lifting the screen ring are fixedly installed on both sides of the upper end of the screen ring.

[0012] Preferably, the upper end of the limiting slide rod is connected to both sides of the upper end of the support platform through a through-hole fit.

[0013] Preferably, there are several electric heating tubes, which are symmetrically distributed sequentially inside the mounting ring, and there are several exhaust fans, which are symmetrically distributed sequentially at the lower end of the mounting plate.

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

[0015] 1. When the vibrating motor is turned on, this utility model drives the screening cylinder to vibrate. When the screening cylinder vibrates, it synchronously drives the screen to vibrate. When the screen vibrates, it vibrates and screens the tea leaves at the top of the screen. Impurities and small tea leaves inside the tea leaves are discharged downwards into the collection box through the impurity discharge cylinder, thus facilitating the screening of the tea leaves. When it is necessary to clean the screen, the handle is lifted upwards to release the positioning groove and positioning boss from limiting the screen. When the screen is released, the screen can be removed from the screening cylinder by continuing to lift the screen. This allows for the simultaneous screening of tea leaves and easy removal and cleaning of the screen.

[0016] 2. This utility model also controls the activation of an exhaust fan when the electric heating element generates high-temperature heat. When the exhaust fan is activated, it blows the high-temperature heat generated by the electric heating element downwards onto the tea leaves on the upper part of the screen for drying. While the tea leaves are being dried, the electric telescopic rod is activated to extend and retract. When the electric telescopic rod extends and retracts, it drives the mounting ring to move up and down linearly. When the mounting ring moves up and down linearly, it drives the mounting plate to move up and down linearly. When the mounting plate moves up and down linearly, it drives the exhaust fan to move up and down linearly. The height adjustment allows the distance between the exhaust fan and the screen to increase or decrease, thereby adjusting the drying effect on the tea leaves. Thus, this device achieves both vibration screening and drying of tea leaves. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution for a screening and drying device for tea processing: it includes a main support frame 1, with a through hole 2 in the middle of the upper end of the main support frame 1. Several support springs 3 are fixedly installed on the upper end of the main support frame 1, symmetrically distributed around the upper end of the main support frame 1. A screening cylinder 4 is fixedly installed on the top of each support spring 3, with the lower end of the screening cylinder 4 passing through the through hole 2. The lower end of the screening cylinder 4 is conical, and a waste discharge cylinder 5 is fixedly connected to the lower end of the screening cylinder 4. Two vibration motors 6 are fixedly installed on both sides of the screening cylinder 4, respectively... The screening cylinder 4 is symmetrically distributed on both sides. A limiting ring 7 is fixedly installed on the inner wall of the screening cylinder 4. A positioning groove 8 is provided at the upper end of the limiting ring 7. A sieve ring 9 is movably connected to the upper end of the limiting ring 7. A positioning boss 10 is provided at the lower end of the sieve ring 9. The positioning boss 10 is movably connected to the inner wall of the positioning groove 8, so that the sieve ring 9 is limited by the positioning groove 8 and the positioning boss 10. Handles 11 for lifting the sieve ring 9 are fixedly installed on both sides of the upper end of the sieve ring 9. A sieve screen 12 for screening tea leaves is fixedly installed on the inner wall of the sieve ring 9. A collection box 13 is movably connected to the inner side of the lower end of the main support frame 1.

[0024] A support platform 14 is fixedly installed on the upper end of the main support frame 1. An electric telescopic rod 15 is fixedly installed through the upper end of the support platform 14. An installation ring 16 is fixedly installed on the telescopic part of the lower end of the electric telescopic rod 15. Limiting slide rods 17 are fixedly installed on both sides of the upper end of the installation ring 16. The upper ends of the limiting slide rods 17 are connected to the upper sides of the support platform 14 in a close fit, so that the installation ring 16 can be linearly limited by the limiting slide rods 17. An electric heating tube 18 for drying tea leaves is fixedly installed inside the installation ring 16. There are several electric heating tubes 18, which are symmetrically distributed in sequence inside the installation ring 16. An installation plate 19 is fixedly installed at the lower end of the installation ring 16. An exhaust fan 20 is fixedly installed through the lower end of the installation plate 19. There are several exhaust fans 20, which are symmetrically distributed in sequence at the lower end of the installation plate 19.

[0025] Working principle: In use, this utility model involves feeding the tea leaves to be dried into the upper part of the screen 12. When the tea leaves are fed into the upper part of the screen 12, the vibration motor 6 is turned on. When the vibration motor 6 is turned on, it drives the screening cylinder 4 to vibrate. When the screening cylinder 4 vibrates, it drives the screen 12 to vibrate synchronously. When the screen 12 vibrates, it vibrates and screens the tea leaves at the upper part of the screen 12. Impurities and small tea leaves inside the tea leaves are discharged downwards into the collection box 13 through the impurity discharge cylinder 5, thereby facilitating the screening of the tea leaves. When the screen 12 needs to be cleaned, the screen ring 9 is lifted upwards by the handle 11. When the screen ring 9 is lifted upwards, the positioning groove 8 and the positioning boss 10 will release the restriction on the screen ring 9. When the restriction on the screen ring 9 is released, the screen 12 can be removed from the screening cylinder 4 by continuing to lift the screen ring 9 upwards. This allows for the screening of tea leaves while facilitating the removal and cleaning of the screen 12.

[0026] By controlling the activation of the electric heating element 18, high-temperature heat is generated inside the mounting ring 16. When the electric heating element 18 generates high-temperature heat, the exhaust fan 20 is activated. When the exhaust fan 20 is activated, the high-temperature heat generated by the electric heating element 18 is blown downwards onto the tea leaves at the top of the screen 12 for drying. While the tea leaves are being dried, the electric telescopic rod 15 is activated to extend and retract. When the electric telescopic rod 15 extends and retracts, it drives the mounting ring 16 to move up and down linearly. When the mounting ring 16 moves up and down linearly, it drives the mounting plate 19 to move up and down linearly. When the mounting plate 19 moves up and down linearly, it drives the exhaust fan 20 to move up and down linearly to adjust its height. This allows the distance between the exhaust fan 20 and the screen 12 to increase or decrease, thereby adjusting the drying effect on the tea leaves. Thus, this device achieves both vibration screening and drying of the tea leaves.
