An apparatus for quantitatively extruding food material is provided. At least one introducing means such as a driven roller having a vane adapted to protrude from it propels the food material into a cylindrical food forming device, which comprises a longitudinal groove and a cylinder having a rectangular opening on a side thereof and encloses the food material for a piston to extrude it from the apparatus. |

DETAILED DESCRIPTION It is an object of this invention to provide an apparatus for quantitatively extruding food material.
It is another object of the invention to provide an apparatus for quantitatively extruding a mixture of food materials such as a vegetable salad, a fruit salad, or paste materials containing liquid and solid food materials.
It is a further object of the invention to provide an apparatus for enclosing a desired amount of food material without allowing air to be introduced into the material.
It is a still further object of the invention to provide an apparatus for enclosing the food material while decreasing the destruction of the fibrous tissue of the vegetable and/or fruit in the mixture, or without separating the juice from the vegetables and/or fruits.
In one aspect of the invention, an apparatus for quantitatively extruding food material comprising a hopper having therein a chamber communicating with a first port and a second port for the chamber, the first and second ports being disposed oppositely of each other on the hopper, a piston mounted to the first port, and a nozzle mounted on the second port, characterized by at least one introducing means disposed in the hopper, means for driving the introducing means, a cylindrical food forming device comprising on the bottom surface of the hopper a longitudinal groove of a semicircular shape in cross-section and a cylinder with front and rear end openings and adapted to revolve slidably within the groove and provided with a rectangular opening at a side thereof having a width approximately equal to the diameter of the cylinder and a length approximately equal to the length of the bottom of the hopper, leaving a semicircular wall, means to revolve the cylinder to form a cylindrical space surrounded by the semicircular wall of the cylinder and said groove, with front and rear end openings, or to juxtapose the semicircular wall of the cylinder with the groove to form a cavity to receive the food material, the front and rear end openings of the cylindrical space communicating with the first and second ports, respectively, and means for advancing the piston from the first port into the cylindrical space to extrude the food material contained therein and retracting to allow the food material to enter said cavity
