Description

Technical Field

[0001] This utility model relates to the technical field of tea pretreatment devices, specifically a tea pretreatment device for the production of cold-dissolved tea polyphenols. Background Technology

[0002] The production process of cold-soluble tea polyphenols involves the extraction and concentration of active ingredients (mainly tea polyphenols) in tea leaves. The tea pretreatment process has a significant impact on the quality and efficiency of the final product. The purpose of the tea pretreatment device is to effectively process the tea leaves, remove impurities, release tea polyphenols, and lay the foundation for the subsequent extraction process.

[0003] For example, a tea pretreatment device for extracting tea polyphenols, as disclosed in announcement number CN223460749U, includes a support frame and a shell. The shell is mounted on the support frame, which is mounted on an external device. A drying mechanism is provided on the support frame. The drying mechanism includes a stirring mechanism, spray nozzles, an air inlet pipe, a flexible pipe, a corrugated pipe, a clamping plate, a fixing plate, a guide rod, and an adjustment mechanism. The stirring mechanism is mounted on the support frame, and multiple spray nozzles are provided. The stirring mechanism ensures that the tea leaves are fully mixed during the drying process, avoiding local overheating or over-humidification. Multiple spray nozzles are installed on the lower end face of the shell and dry the tea leaves by spraying hot air. The air inlet pipe is connected to an external air inlet device to provide hot air to the spray nozzles. The flexible pipe is connected to the air inlet pipe and the spray nozzles to ensure smooth transmission of hot air. The corrugated pipe is connected between two clamping plates, improving the adaptability of the device.

[0004] The aforementioned patent proposes that hot air can be sprayed to dry tea leaves, ensuring that the tea leaves are fully mixed during the drying process. However, in the process of using the tea pretreatment device, the tea leaves are directly poured into the processing shell for drying and stirring. Since the tea leaves are relatively intact, the outer layer dries first, and the internal moisture is difficult to evaporate, resulting in uneven moisture evaporation. This can easily lead to poor taste and aroma of the dried tea leaves, and cause some tea leaves to become moldy. Utility Model Content
