Reference numeral 23 is a protrusion formed on the handle 22 at a position of 90 degrees from the mounting shaft 24. When the handle 22 is slid in the outer peripheral direction in a tilted state, the protrusion 23 passes through the notch 21 of the annular wall portion 17. The cylindrical filter 15 projects from the outermost diameter (outer diameter of the annular wall portion 18) and engages with the engagement hole 14 of the centrifuge basket 10.

When using, the mounting shaft 24 of the handle 22 of the tubular filter 15 is accommodated in the recess 13 of the centrifuge basket 10 and stored, and the handle 22 is tilted. In this state, handle
The protrusion 23 of 22 is fitted in the notch 21 of the annular wall portion 17.

Then, the electric motor is driven to insert the material from the material inlet 8 of the container lid 7, and the cutter 12 of the centrifuge basket 10 is inserted.
