TECHNICAL FIELD
[0001] The utility model relates to cold tea powder technical field, concretely is a kind of multistage grinding device of cold tea powder. BACKGROUND
[0002] Cold tea, that is, with cold water to brew tea leaves, can be said to be a kind of tea brewing method overturning tradition, office workers, class people, drivers, mountaineers, etc., wherever they go, as long as mineral water can be bought, cold tea that is good to drink and health-care can be enjoyed at any time, the life tea culture is more with hot boiled water to brew, can enjoy the elegant fragrance of tea leaves, taste the sweet and mellow taste in tea soup, also a kind of leisure hobby, with the acceleration of people's life rhythm, this lifestyle of cold tea begins to be widely accepted by the public.
[0003] The inventor found the following problems in the prior art during the implementation of the utility model: 1. The grinding tool is a grinding rod, which is usually made of high-hardness materials such as wood, stone or metal. The wood grinding rod is relatively soft in texture and does not easily damage the cell structure of tea leaves during grinding, making it suitable for high-grade tea varieties that require fine grinding and have high quality requirements. The grinding rod has a single layer for grinding, and single-layer grinding usually cannot make tea particles consistent in size. Because the pressure and friction force on the tea leaves are unevenly distributed during grinding, the tea leaves near the edge of the grinding tool or the key position of the grinding motion path will be ground finer, while the tea particles at other positions may be coarser, resulting in uneven grinding. 2. The grinding device adopts multiple layers for grinding. Because there is only one direction of grinding action, the grinding trajectory is linear, causing the grinding area to be concentrated on the path of the grinding component's movement, while other areas are not ground enough. For example, when grinding a large area of metal plate, one-way grinding causes a large difference in grinding degree between the center and the edge of the plate. The center is ground more frequently and is smoother, while the edge is relatively rough, affecting the overall quality and surface flatness of the product, and causing uneven stress on the overall ground tea leaves.
