Technical Field
[0001] The invention relates to the technical field of food processing, in particular to a black tea processing equipment monitoring system. Background Art
[0002] The black tea processing equipment supervision system originated from the automation needs in the traditional tea processing process. With the expansion of the tea market and the improvement of quality standards, traditional manual operation methods have gradually failed to meet the efficiency and consistency requirements. In the mid-to-late 20th century, preliminary mechanized equipment was introduced into the black tea processing links, such as withering, rolling and fermentation. With the development of industrial automation and intelligent control technology, modern black tea processing equipment supervision systems have gradually integrated sensors, data acquisition and remote monitoring technologies, realizing precise control and quality tracking of the processing process, and improving product consistency and production efficiency.
[0003] However, when the black tea processing equipment supervision system is applied to the fermentation and drying processes, there are the following technical disadvantages:
[0004] 1. Insufficient sensitivity to parameter fluctuations: Parameters such as temperature and humidity during the fermentation and drying process are crucial to the quality of tea. However, the existing regulatory system responds slowly to tiny parameter fluctuations, making it difficult to accurately control the optimal fermentation and drying conditions in actual operations, affecting the stability of the tea's taste and aroma.
[0005] 2. Limitations of sensor accuracy and durability: Under long-term high temperature and high humidity conditions, the accuracy of the sensor may decrease, and deviations or failures may occur, resulting in the system being unable to obtain accurate data, affecting the quality monitoring of the fermentation and drying stages. This problem is particularly evident during high-load operation.
[0006] 3. Insufficient system data integration: The current system is still insufficient in real-time data integration and analysis of the fermentation and drying processes. It is unable to quickly identify abnormal situations and make effective adjustments. In addition, the data sharing and linkage between the various processes are not close enough, resulting in a delayed system response and affecting overall production efficiency. Summary of the invention
