I. Introduction of Pet Chews Food

Traditional pet chews food are mostly meat strips made from pigskin and cowhide, soaked, folded by hand, and dried.The modern pet chews are made of natural starch, natural gum and meat products through mixing, extrusion, shaping, drying and other processes.

Chews produced by extrusion process not only have the necessary characteristics of long-lasting chewing, high nutrition, and high palatability, but also are easy to digest and safe and hygienic due to the high-temperature processing technology. In addition, flexible raw materials combinations, extrusion parameters and shaping process can develop more functional, high-quality and more interesting chewing products to meet the needs of pets for teeth cleaning and calcium supplementation in different periods.

10. Steam boiler (Optional)

Notice:

Single-screw extrusion pet chews food production line is optimal for producing general purpose pet chews.

• The cooking time of the material is long, and compared to twin screw extrusionprocess, the product extruded by the single-screw extrusion technology has higher density.
• By changing different extrusion dies, different shapes of pet chews can be produced, such as bars, granules, flakes, bones, twists etc.
• Its equipment investment is low, and it occupies a small floor area, which is suitable for small pet food

There are another three kinds of dog cat chews requiring different specific chews food production lines. DAYI engineers will formulate the most suitable production plan for you according to your needs.

• Another die-casting dog cat chews of more complex shapes are produced by the pet food production line consisting of twin screw extrusion and vertical die casting processes, instead of thesingle screw extrusion process.
• In addition, when the content of fat and fresh meat in the raw material is high, because the moisture and fat in the raw animal raw material will offset the friction in the extruder barrel, making it difficult or even impossible to reach a proper cooking temperature, so a secondary continuous extrusion molding process is required: twin screw process plus single screw process.
• CO-extrusion pet chewsrequires two sets of single screw extruders to work at the same time.
