A high speed subdividing and filling apparatus for liquid food containing solids therein comprising: a fixed quantity cut-down pump body having an absorption opening in communication with a lower-end opening of a liquid food accommodating container and having a discharge opening; an inner cylinder turnably fitted in the fixed quantity cut-down pump body; a piston slidably fitted in the inner cylinder; and a through-hole formed in the inner cylinder, wherein rotation of the inner cylinder and forward/backward movement of the piston are coupled so as the through-hole of the inner cylinder is communicated with the absorption opening of the cut-down pump body, the piston moves back to fill liquid food into the inner cylinder and as the through-hole of the inner cylinder is communicated with the discharge opening of the pump body, the piston advances to discharge liquid food from the discharge opening.
