Additive-free ampelopsis grossedentata tablet and preparation method thereof

The invention discloses an additive-free ampelopsis grossedentata tablet which is prepared by the following steps: crushing stem-removed ampelopsis grossedentata, sieving with a 100-150-mesh sieve to obtain ampelopsis grossedentata powder to be tableted, and directly tabletting and forming under the pressure of 25-100kN to obtain a mechanically stable pure ampelopsis grossedentata tablet, namely the additive-free ampelopsis grossedentata tablet. Compared with an existing vine tea tablet processing technology, auxiliary materials do not need to be added, a granulation step is not needed, direct tabletting forming is achieved, operation is simpler and easier, the process is more energy-saving and environmentally friendly, and the production cost is lower. All functional components such as dihydromyricetin, selenium, polysaccharide and dietary fibers in the ampelopsis grossedentata are reserved, and the health-care effect is more comprehensive. 本发明公开一种无添加藤茶片，由如下步骤制备得到：将去茎梗的藤茶粉碎过100-150目筛网，获得待压片藤茶粉，在25-100kN压力作用下
