Description

Tea fermentation and drying integrated machine Technical Field The invention relates to the technical field of tea processing, in particular to a tea fermentation and drying integrated machine. Background In the field of tea processing, fermentation and drying are key processes for determining tea quality, flavor and stability. The fermentation process is carried out in a proper and stable temperature and humidity environment to promote the enzymatic oxidation of substances in the tea to form special aroma and taste of specific tea, and the drying process is used for rapidly stopping the fermentation reaction, removing excessive water and fixing the quality to prevent the tea from mildew or deterioration in the subsequent storage. The traditional tea processing generally takes fermentation and drying as two independent working procedures, and the two working procedures are respectively finished in special equipment, so that the process is complicated, the manual intervention is frequent, and tea damage and environmental parameter fluctuation are easily caused in the material transferring process, so that the product consistency and the processing efficiency are affected. In order to solve the above problems, in recent years, devices integrating fermentation and drying functions have been developed in industry. However, existing integrated devices still have significant technical drawbacks. For example, although some devices realize function switching in the same cavity, a high-efficiency moisture quick discharging mechanism is lacking, residual moisture is difficult to remove in time when the high-humidity fermentation state is switched into a drying stage, so that the thermal efficiency is low in the initial stage of drying, and even caking or local overheating of the surface of tea leaves is caused, and the uniformity of a finished product is influenced. In addition, the equipment adopts a complex mechanical turning structure, such as a sliding frame matched with a lifting scraping plate, although the aim of improving the uniformity of materials is achieved, the problems of high manufacturing cost, poor operation reliability and the like are caused by complex structure and more transmission links, and the bottom heating mode is easy to cause the obvious temperature difference between the upper part and the lower part in the cavity, so that the accurate regulation and control of the whole-area temperature and humidity are difficult to realize. In addition, the existing equipment has the defects in the aspects of tightness, real-time monitoring of environmental parameters and automatic control, and restricts the stable and standardized production of high-quality tea. Therefore, what is needed is a tea fermentation drying device which is reasonable in structure, accurate in temperature and humidity control, efficient in moisture discharge, stable in operation and convenient to operate, so that fermentation and drying processes are effectively integrated, and the overall efficiency and quality consistency of tea processing are improved. Disclosure of Invention The invention provides a tea fermentation and drying integrated machine, which solves the problems of low equipment integration level, easiness in pollution in a material transferring process, insufficient temperature and humidity control precision, easiness in clamping and wearing of a material turning mechanism, poor sealing reliability, low moisture removal efficiency and the like caused by independent tea fermentation and drying procedures in the prior art.
