手动式紧压绿茶机设计 PAGE 1 摘要 目前，茶叶市场上出现的一些球状、圆饼状等高档绿茶产品，价格高，市场潜力大，具有使用方便，易携带的特点，可广泛用于宾馆、旅游及办公场所。但其加工主要是用布手工包揉而成，劳动强度大，耗工时，生产效率低。考虑到茶农的经营特点，茶农的购买力 以及茶叶加工的季节性，笔者研制了手动式紧压绿茶机。该机结构简单，体积小，质量轻，价格低。 本文论文析我国茶叶加工现状，设计出一种紧压绿茶加工机械。手动式紧压绿茶机主要由机座、上模、下模、转盘、压杆、手柄等零部件组成，其中机座内还有轴(齿条 )、齿轮等零件。上模与轴采用锥孔连接，转盘上加工有6个下模孔，上、下模及下模孔的直径大小由加工成型的茶叶产品直径决定，改变下模高度来控制成型茶叶产品的重量。压制步骤为：将半烘炒好的绿茶及时放人下模孔内，转动转盘，与上模对中后，按下压杆进行压制，退出上模，转动转盘，用手柄将压制成型的茶叶抵出。将绿茶通过专用机具加工成小块的紧压茶，不需复水蒸压，保持绿茶原有的形态和品质，并可将绿茶加工成各种形状、大小一样的紧压茶，以及加工表面带字的紧压茶。这种茶耐储藏，饮用既方便又卫生，还能保持和提高了绿茶的原有形态和品质。所具有的优点使其带来很高的附加值, 本次毕业设计对这种机械进行初步的设计和研究。 关键词：手动压紧，紧压绿茶 全套图纸加扣 3346389411或3012250582 Abstract At present, the tea market, some spherical, round cake and other high-grade green tea products, high prices, market potential, with easy to use, easy to carry features, can be widely used in hotels, tourism and office space. But its processing is mainly made with cloth hand-kneaded, labor-intensive, time-consuming, low production efficiency. Taking into account the operating characteristics of tea farmers, the purchasing power of tea farmers and tea processing season, I developed a manual pressure green tea machine. The aircraft structure is simple, small size, light weight, low prices. This paper analyzes the present situation of tea processing in China, and designs a kind of pressing green tea processing machinery. Manual pressing green tea machine mainly by the base, on the mold, the next model, turntable, pressure bar, handle and other components, including the base there are shaft (rack), gear and other parts. The upper die and the shaft are connected with the tapered hole. The diameter of the upper and lower die and the lower die hole is determined by the diameter of the processed tea product. The height of the mold is changed to control the weight of the molded tea product The The pressing step is to place the semi-baked green tea in the lower mold hole, turn the turntable, and press it against the upper mold, press the pressing bar to suppress, exit the upper mol
