To provide a power type tea grinding device developed due to the desire of more delicious and easily drinkable tea and the determination to break through a present state, in view of the fact that a present popular drinking method of green tea is nearly close to a limit, and the residues of tea leaves containing much more health components are unconsciously disposed, and a device and a preparation method by pulverization and grinding expressions seen in previous patent literatures are far from a planned target including taste.SOLUTION: A base of a special shape is developed and is formed in a shape of radially assembling a plurality of pestles so as to make the pestles smoothly turn with power on a recessed surface in a mortar, and the pestles are mounted only on the tip end part via an intermediate shaft. As a result of this, it becomes possible to downsize a shape volume of the pestle and see follow-ups for the pestles as consumables.SELECTED DRAWING: Figure 1【課題】 現在普及している煎茶等の飲用手法はほぼ限界に近い、更に多くの健康成分を含む茶葉の残さは無意識に廃棄されている。もっと美味しく手軽に飲めるお茶が欲しい、何とか現状を打破したいとの一念で開発したのが「動力式・お茶擂り器」である。又先行特許文献等に見られる粉末化及び擂り潰しの表現による機器及び製法は味覚と共に当方の画する目標とはほど遠いものである。【解決手段】 スリコギがすり鉢内の凹面を動力でスムーズに廻る為に、特殊形状の台座を開発し複数本のスリコギを放射状に組み込む形状とした、更にスリコギは中間シャフトを介して先端部のみに装着する事とした、結果的にはスリコギの形状容積の小型化も図れ、消耗品であるスリコギの事後対応も見通す事が出来た。【選択図】図１
