Description

Technical Field

[0001] This utility model relates to the technical field of tea fixing and processing equipment, specifically to a microwave and light wave composite fixing device for tea. Background Technology

[0002] In the field of tea processing, fixation is one of the key steps in the tea making process. Its purpose is to quickly destroy the enzyme activity in the tea leaves through high temperature, fix the color and aroma of the tea leaves, and lay the foundation for subsequent processing. Traditional tea fixation methods mainly include pan-frying fixation and drum fixation. Although these methods can meet the needs of tea processing to a certain extent, they have problems such as high energy consumption, low processing efficiency, and uneven fixation.

[0003] In recent years, with the rapid development of microwave and light wave technologies, their application in the tea processing field has gradually attracted attention. Microwave heating has the advantages of fast heating speed, strong penetration and uniform heating, which can effectively improve the efficiency and quality of tea fixation. Light wave heating can further promote the vibration of water molecules inside the tea leaves, enhance the fixation effect of the tea leaves, and at the same time maintain the freshness and color of the tea leaves.

[0004] Currently, most tea-fixing devices on the market use a combination of microwave and light wave methods for large-scale tea production. These devices typically use conveyor belts to transport the tea leaves. While conveyor belts improve efficiency due to the relatively short fixing time and the ability to feed from one side and discharge from the other, they also result in tea leaves constantly piling up on the belt, lacking proper agitation. This negatively impacts the fixing effect and causes inconvenience for users. Therefore, we propose a microwave-light wave combined fixing device for tea. Utility Model Content

[0005] The purpose of this invention is to provide a microwave and light wave composite fixation device for tea leaves, so as to solve the defects mentioned in the background art.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figures 1-4This utility model provides a technical solution: a microwave light wave composite fixation device for tea, including a processing box 1, with material holes 10 provided on both the left and right side plates of the processing box 1, the material holes 10 being used for feeding and discharging operations;

[0029] Specifically, two symmetrical side plates 13 are fixedly installed on the left and right side panels of the processing box 1. A rotating shaft 14 is rotatably connected between the two side plates 13. The two rotating shafts 14 are connected by a mesh conveyor belt 15. The mesh conveyor belt 15 passes through the material hole 10. A geared motor 16 is coaxially installed at the end of one of the rotating shafts 14. The mesh conveyor belt 15 has a mesh-shaped belt structure. The output shaft of the geared motor 16 is fixedly installed on the rotating shaft 14. The geared motor 16 is fixedly installed on the processing box 1, so that the mesh conveyor belt 15 can be properly ventilated. In addition, as the mesh conveyor belt 15 rotates, it can transport tea leaves.

[0030] Specifically, two sets of symmetrical light wave generators 3 and two sets of symmetrical microwave generators 30 are fixedly installed on the cavity wall of the processing box 1. The microwave generators 30 are located between the upper and lower sides of the mesh conveyor belt 15, and the light wave generators 3 are located above the mesh conveyor belt 15. The microwave generators 30 can generate high-power, high-frequency microwave energy, which causes the water molecules in the tea leaves to vibrate and heat up rapidly, achieving a rapid temperature rise to the passivation temperature of the active oxidase. The light wave generators 3 can utilize the thermal effect and photophysical action of light waves to further enhance the fixation effect of the tea leaves, improve uniformity and penetration.

[0031] Specifically, inclined baffles 4 are fixedly installed on the inner walls of both sides of the processing box 1, and a base plate 40 is fixedly installed between the two inclined baffles 4. The base plate 40 is located between the upper and lower sides of the mesh conveyor belt 15. Two symmetrical fans 41 are fixedly installed on the base plate 40 to ensure that the fans 41 can work during use to blow the tea leaves on the mesh conveyor belt 15, promote the turning of the tea leaves, and improve the fixation effect.

[0032] In this embodiment, an inclined scraper 11 is fixedly installed on the top wall of the feed hole 10 at the feed end. The inclined scraper 11 is set at a downward inclination of 30° to 60°. By setting the inclined scraper 11, it is possible to avoid excessive accumulation of tea leaves on the mesh conveyor belt 15 at one time. When there is too much accumulated tea leaves, the tea leaves can be scraped to the part of the mesh conveyor belt 15 with less tea leaves under the blocking action of the inclined scraper 11, so that the tea leaves on each part of the mesh conveyor belt 15 are spread more evenly.

[0033] Specifically, multiple support legs 12 arranged in a matrix are fixedly installed on the bottom surface of the processing box 1. The height of the support legs 12 is between 10cm and 15cm, so as to realize stable support operation by using the support legs 12.

[0034] Furthermore, the inclined baffle 4 is set at a downward inclination of 60°, and the side of the mesh conveyor belt 15 is attached to the inner surface of the inclined baffle 4, so that even if the tea leaves blown down onto the inclined baffle 4, they can continue to fall down onto the mesh conveyor belt 15.

[0035] In addition, the front panel of the processing box 1 is provided with two symmetrical exposed chambers 17. The side walls of the exposed chambers 17 are hinged with doors 18. Door locks 181 are fixedly installed on the doors 18, and handles 182 are also fixedly installed on the doors 18 to facilitate opening the doors 18 for maintenance and other operations.

[0036] It is worth noting that an exhaust hood 2 is fixedly installed on the top of the processing box 1, and an exhaust pipe 20 is fixedly installed on the top of the exhaust hood 2, so that the exhaust operation can be carried out normally.

[0037] Finally, it should be noted that the geared motor 16, microwave generator 30, light wave generator 3, and fan 41 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0038] In use, the microwave and light wave combined fixation device for tea involves feeding tea leaves onto the mesh conveyor belt 15, connecting the geared motor 16 to an external power source, and rotating its output shaft to drive the rotating shaft 14. The rotating shaft 14 then drives the mesh conveyor belt 15, thus conveying the tea leaves. Simultaneously, the microwave generator 30 and the light wave generator 3 are connected to an external power source. The microwave generator 30 generates high-power, high-frequency microwave energy, causing the water molecules in the tea leaves to vibrate and heat up rapidly, reaching the passivation temperature of the active oxidase. The light wave generator 3 utilizes the thermal and photophysical effects of light waves to further enhance the fixation effect, improving uniformity and penetration. Finally, the fan 41 is connected to an external power source and operates, blowing upwards to agitate the tea leaves on the mesh conveyor belt 15, promoting leaf turning.
