Description

Technical Field

[0001] This utility model relates to the field of tea leaf processing technology, and in particular to a tea leaf dehydration and dehumidification device. Background Technology

[0002] Dehydrating and removing moisture from fresh tea leaves is a key step in tea processing. Its purpose is to remove excess moisture from the fresh leaves, laying the foundation for subsequent processes such as fixing and rolling, while also reducing the oxidation reaction of active enzymes in the tea leaves and preventing the tea quality from deteriorating.

[0003] Currently, the mainstream dehydration and dehumidification methods in the industry are mainly divided into two categories: natural sun-drying and heating and roasting. Natural sun-drying is greatly restricted by weather conditions, has low dehydration efficiency, and is easily contaminated by environmental dust and insects, and has been gradually phased out by large-scale production. Although heating and roasting is more efficient, existing equipment still has many technical defects in practical applications. For example, it requires manual turning of the tea leaves, otherwise the leaves are prone to stacking and sticking together, making it impossible for the fresh leaves in the center of the stack to fully contact the heat source, resulting in local over-drying and scorching, and local moisture residue, which seriously affects the consistency of tea quality. Secondly, the heat source is located in a single position and the heat distribution range is narrow, resulting in uneven heating of the fresh tea leaves and affecting the drying effect of the tea. Utility Model Content

[0004] The purpose of this invention is to provide a dehydration and dehumidification device for fresh tea leaves. It can increase the heating range of fresh tea leaves by heating the water, and with the tea leaves being dispersed inside the dehumidification cylinder, the tea leaves can fully and evenly contact the heat source to improve the dehydration and drying effect. It can also fully stir the water inside the water tank, so that the heat of all parts of the water inside the tank is consistent, thereby further improving the dehydration and drying effect of the tea leaves. At the same time, the dispersion component and the stirring component only need to be driven by a single power source, the motor, which has low energy consumption and strong practicality.

[0005] To achieve the above objectives, a dehydration and dehumidification device for fresh tea leaves is provided, comprising:

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0033] Working Principle: During operation, the motor 12 is started and the heating element 9 is controlled by the thermostat 10 to heat the water inside the water tank 1. Then, the tea leaves are poured into the dehumidification cylinder 3 through the feed hopper 2. Under the heating effect of the water inside the water tank 1, heat can be transferred to all parts of the outer surface of the dehumidification cylinder 3 to increase the heating area inside the dehumidification cylinder 3. Then, the fresh tea leaves inside the dehumidification cylinder 3 are dehydrated and dried. Subsequently, under the action of the motor 12, the drive shaft 13 drives the dispersing blades 14 to stir and disperse the fresh tea leaves inside the dehumidification cylinder 3, so that the fresh tea leaves are always in a dispersed state and fully contact the inner wall of the dehumidification cylinder 3 for dehydration and drying, thereby effectively improving the dehydration and drying effect of the fresh tea leaves. In addition, the drive wheel 15 and belt... 16. Under the transmission action of the synchronous wheel 18, the first conical tooth 19 will be driven to rotate synchronously through the transmission shaft 17. Then, under the meshing action of the first conical tooth 19 and the second conical tooth 21 and the first conical tooth 19 and the third conical tooth 24, the first stirring blade 22 and the second stirring blade 25 will be driven to rotate in opposite directions through the stirring shaft 20 and the sleeve rod 23 respectively. This will ensure that the water in the water tank 1 is fully stirred, thereby effectively ensuring that each part of the water can fully contact the heating tube 9, ensuring the consistency of the water temperature in the water tank 1, and further improving the dehydration and drying effect of the fresh tea leaves. At the same time, the breaking up of the fresh tea leaves and the stirring of the water only require the single power source of the motor 12 to drive, which has low energy consumption and strong practicality.
