Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tea drying, in particular to a tea dryer with electrostatic adsorption dust removal and high efficiency drying. BACKGROUND

[0002] The tea dryer is an indispensable key equipment in the modern tea processing system, and the development and wide application of the tea dryer mark an important transition of tea production from traditional handmade to mechanization, standardization and large-scale. In the initial processing flow of tea, "drying" is a crucial process, which not only evaporates the excess water in fresh leaves (reduces the water content from 60%-70% to 3%-5%) for long-term storage and transportation, but also terminates the enzyme activity through heat to fix the quality characteristics of tea, and develops the unique aroma, color and taste of tea. Before the popularization of mechanized tea making, tea drying completely relied on traditional methods such as sun drying, charcoal baking or pan frying. Although these methods can produce tea with distinctive characteristics, they have significant drawbacks such as low efficiency, high labor intensity, severe weather dependence, difficult control of hygiene conditions and unstable quality. The product quality is highly dependent on the personal experience of the tea maker, making it difficult to achieve batch production and standardization, which restricts the modernization development of the tea industry. Modern tea dryers usually adopt the working principle of hot air circulation, which is composed of a heat source device (such as coal, oil, gas or electric heating), a fan, a conveyor belt (or an oven), a control system and other parts. Its core advantage is to provide stable, uniform and controllable hot air temperature and flow rate, ensuring uniform heating and consistent drying degree of the same batch of tea, thereby greatly improving the overall quality and commodity value of tea. The popularization and application of tea are an important milestone for the tea industry to move towards industrialization and modernization, which not only significantly improves production efficiency and economic benefits, ensures the stability of product quality and hygiene safety, but also lays a solid foundation for global consumers to enjoy tea beverages with stable flavor and excellent quality throughout the year. The existing public document CN107624894A discloses a high-efficiency tea drying and dust removal device, which includes a bottom plate, a shell arranged on the bottom plate, support rods symmetrically arranged on the bottom of the shell, the shell being welded on the bottom plate through the support rods, a feed hopper arranged on the top left side of the shell, a guide plate fixedly arranged on the inner left wall of the shell, the guide plate being inclined downward, a partition plate fixedly arranged at the bottom end of the guide plate, the partition plate being vertically arranged and fixed at the bottom of the shell. The present application provides a high-efficiency tea drying and dust removal device with novel structure. The present application has compact structure and reasonable structure arrangement. The present application ingeniously sets up a wind cavity to dry tea from bottom to top, which is heated uniformly and completely to realize high-efficiency drying. In addition, the present application ingeniously sets up a dust removal cavity to use electrostatic dust removal to efficiently adsorb dust and fine particles in the shell, realizing high-efficiency dust removal during the drying process. In addition, the present application facilitates the discharge of tea. However, the device still has the following defects: But in actual application, it is found that in order to pursue efficiency, the existing drying equipment often exposes tea directly to high-temperature hot air, which is easy to destroy the active ingredients (such as tea polyphenols, amino acids, etc.) in the tea, resulting in loss of aroma, darkening of color, and even burnt smell, which seriously affects the quality and economic value of high-end tea. At the same time, during the drying, conveying and tumbling process of tea, the dust, debris and fine broken ends attached to the surface of tea are easy to fall off, forming dust. The traditional equipment lacks efficient dust removal means, relying only on simple filtration or natural sedimentation, which causes these dust to re-adsorb on the surface of tea, resulting in low cleanliness of finished tea, turbid tea soup during brewing, and affecting the consumer experience. Especially the tea that has not been completely dried, has certain viscosity, and is easy to accumulate and block in the feeding pipe and conveying equipment. This not only affects the continuity of production, but also causes uneven heating and drying of tea, resulting in differences in quality of tea in the same batch. SUMMARY
