Description

Technical Field

[0001] The utility model relates to the technical field of tea dryers, specifically to a multifunctional dryer for tea processing. Background Technique

[0002] As a traditional Chinese beverage, tea processing has a crucial impact on the quality of the final product. Drying, as one of the key links in tea processing, directly affects the color, aroma, and shelf life of tea. With the continuous progress of technology, tea processing and drying technologies are also constantly updated to meet the market's demand for high-quality tea.

[0003] Traditional drying methods rapidly dehydrate tea by manual kneading and high-temperature frying. This method can effectively block tea fermentation, but the production process is complex, labor-intensive, and difficult to apply on a large scale. Currently, in order to achieve efficient drying and save labor, corresponding mechanical dryers are usually used for drying operations. There are many types of dryers on the market. Since the dryer needs to maintain air circulation, at this time, most dryers are provided with a mesh-like plate body or conveyor belt for placing tea. However, after the tea is dried, the tea is relatively brittle and prone to breakage and generate debris. At this time, the debris will directly fall into the dryer.

[0004] Most dryers lack corresponding debris dropping holes and windows for dust cleaning at the bottom, which is not conducive to discharging the debris falling inside to the outside, and is also not conducive to dust cleaning operations. When the debris falls on the internal electric heating rod, it will affect the heating effect of the electric heating rod. At the same time, when there is too much debris, it is also easy to cause a fire under high-temperature conditions, bringing inconvenience to users. In view of this, we have proposed a multifunctional dryer for tea processing. Summary of the Utility Model
