15 Claims. (01. 226-83)
This invention relates to an improved method The extrusion of material from tank I is con
and apparatus for extruding a- meat product.
trolled by cock 8 in line 5.
'
One of the objects of this invention is to pro- '
My improved extrusion nozzle may be formed
vide an improved means for ?lling trays with a

Another object of this invention is to provide
an improved extrusion nozzle in which a com-
minuted meat product under'pressure is forced
10 through an elevated, graduated passageway in a
from sheet metal or other suitable material and
comprises a cylindrical collar portion 9 provided 5
‘at one end with radialv ?ange Ill and at its
opposite end with an upwardly extending, out- w
wardly ?ared passageway II. In practice, pas
sageway II is elevated susbtantlally 39° and in
the course of its elevation assumes the shape of a 10
manner preventing the formation of air pockets
therein.
Another object of this invention is to provide
substantial rectangle gradually' increasing in
width and decreasing in height,

elevated passageway to cause a back pressure,
said passageway being graduated to an opening

for suitably dispensing the product. The side 15
walls of downward portion I3 are parallel
throughout their length and preferably de?ne an
opening of common relationship to passageway
I I at its highest point in elevation. Flange mem
ber I4 is welded or otherwise secured at open end 20
I2 at right angle to downward portion I3.
I have found that meat loaves formed from a
comminuted product contain, to a large degree, a
number of air pockets of varying sizes. Such
N) (A air pockets have a deleterious effect upon the
?nished product, prevent a maximum weight in
a minimum sized loaf and .cause an unsightly
appearance in the sliced product. By use of my
present method and apparatus, I am able to pro30 vide maximum emclency in the formation of meat

result in the material passing therethrough and
cause the material to compact in a manner de
void of air pockets. This back pressure, assisted 35
by the decreasing height of passageway II,1will -.
also cause the material to spread evenly with the
increasing width of passageway II.

Flange I4 is in operative relationship with tray
I1 and serves to prevent the product extruded 40
from opening I2 from rolling or folding over dur- ing the filling or tray 11, by which the product
is continuously compacted free of air pockets
