Premium products

For the tests depicted in the tables on
p. 7, the products were mirrored after
industry-typical dry expanded petfoods.
Further testing was completed that allowed for
a product with an intrinsic moisture of 12% and
a further addition of another 50% moisture, for
a total product moisture (entering the extruder)
at more than 60%. These results now include
the premium and
superpremium range
of products in the
envelope of capability
for the Model E975
Extruder System.

A basic co-extrusion test run of a simple large bone-shaped treat was completed to acquire the characteristics of the Model E975 Extruder in a pet treat style

architecture. The “bone shell” component recipe consisted of 66% starch, 11% protein, 1% fat and 11% moisture (humectants and palatability enhancers not included). The “marrow filling”

recipe consisted of 40% starch, 30% protein,

6% fat and 10% moisture (humectants and palatability enhancers not included).

The blend of “bone” and “marrow” ranged from 50/50 to approximately 80/20 (depicted above). The bone component was produced on a Model E525 Extruder with a 16X72 DCC, both set up in the specialty/treats configuration, with a production rate of 500 - 750 lbs/hr. The marrow filling was produced on the Model E975 Extruder with a 16X72 DCC, with the DCC configured as it was for the bone, with a production rate that varied from 500 lbs/hr to 200 lbs/hr.

No need to keep them close

The important factor to consider with this production trial is that the two extruders were 15 feet apart. This is important in that previous attempts to produce this product required that the two extruders be no more than 3 feet apart. ■
