I. Introduction of CO Extrusion Pet Chews

CO extruded pet chews typically consist of two-part extrudates from two different formulations. Each formula provides some kind of outstanding chewing effect to pets. For example, under the premise that the two parts of a CO extruded pet chew have all the basic properties expected from a chew such as long-last chewiness and good palatability, then at the same time one part of the formula may be dedicated to freshening breath, and the other part is dedicated to supplementing extra nutrients; or one part may have antibacterial effect, and the other part has the good meaty smell to increase the pet’s attention, etc.

Co-extrusion pet chews are made by co-extrusion technology. Two sets of single-screw extruders are used to handle different formulas simultaneously. The extrudates from the two dog food extruders were then co-extruded at the same die. In additiona to CO extrusion, regular single-color or single-recipe chews can be produced once the dog treat extruder is used alone.

Notice:

1. Production of die-cast chews such as bones and toothbrushes requires twin-screw extrusion and vertical die-casting processes rather than CO extrusion process.
2. When the content of oil and fresh meat in the raw material is high, the Secondary Extrusion Process is required: firstly use a twin-screwdog treat extruderfor precooking, and then continue to use a single-screw dog treat extruder for obtaining high density, chewy, flexible and leathery texture.
