Title: Agitating device
Inventor: KONDO SHIGEKAZU
IPC: B67D1/07
Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To simply repair or the like an agitating mechanism section. SOLUTION: A supporting shaft 30 is protruded from a deep wall 15B of a bottom section of a mixing container 15, and an impeller 31 with a magnet embedded on its back is rotatably supported on the supporting shaft 30. A rotor constituting a magnet coupling between the impeller 31 and the deep wall is provided on the outside of the deep wall 15B. Recessed and projected faces 46 and 47 forming a fine lattice shape are formed on the back of the impeller 31 and the deep wall 15B facing the impeller.  When pulverized tea T is infiltrated into a clearance between the back side of the impeller 31 and the deep wall 15B, the pulverized tea T is so melted well as to be ground down between both recessed and projected faces 46 and 47 following the revolution of the impeller 31, although the pulverized tea is easily left unmelted as agitating flows are weak, to avoid the adhesion of the unmelted pulverized tea T. Cleaning, therefore, can be simply carried out.
