Abstract
An apparatus for filling two cylindrical canning containers with cylindrically compacted and shaped tuna chunks. The apparatus has a flared compression channel for relieving excessive compression in the compacted tuna chunks, a movable shaping wall for controlling the density of the tuna chunks by changing the volume of the channel, and a movable blade between two semi-cylindrical cavities in the shaping wall for splitting the relieved compacted tuna chunks into two streams which then flow easily into the cavities for forming semi-cylindrical ends prior to cutting the formed ends into cylindrical cakes for injection into the canning containers.
Claims7
An apparatus for filling a canning container with a shaped foodstuff product, such as tuna tish, comprising a rectangular shaped channel for receiving sliced pieces of tuna, a plunger for compacting the pieces in the channel into a mass of a predetermined density, a shaping end wall having a pair of semi-cylindrical cavities for forming a pair of scallop-like semi-cylindrical ends in the mass, a cutter for separating the scallop-like semi-cylindrical ends in half, a pair of shaping dies for cutting the scallop-like cylindrical ends into two cylindrical cakes, and a pair of pistons for ejecting the cakes into two canning containers;
- wherein,
- the shaping end wall (33) is slidably mounted in the channel (6) for controlling the density of the mass (4) by changing the volume of the channel;
- and wherein,
- the channel is provided with a flared portion (39) for expanding the mass and releasing excessive compression adjacent the semi-cylindrical cavities (14) in the shaping end wall;
- characterized in that:
- the cutter (10) is slidably mounted between the cavities in the shaping end wall for moving into the flated mass in the flared portion of the channel and starting two streams for easily compacting into the cavities in the shaping end wall concomitant with the shaping dies (9) cutting two preceding streams nested in and upstream of the cavities in the shaping end wall into the two cylindrical cakes (40).
A method for filling a canning container with a shaped foodstuff product comprising the steps of:
- compacting slices of the foodstuff into a mass in a channel;
- controlling the density of the mass by changing the volume of the channel;
- moving the mass into a flared portion of the channel and relieving the mass of excessive compression;
- splitting the relieved mass in the flared portion of the channel into two component streams;
- flowing each stream from the flared portion of the channel into respective semi-cylindrical cavities and forming semi-cylindrical ends;
- passing a cutter into the streams upstream of the semi-cylindrical ends and forming cylindrical cakes;
- and filling the canning containers with the cakes.
