Pet Feed Extrusion Machine Introduction

The pet feed extrusion machine applies high temperature, high pressure, and intense extrusion to instantly puff, expand, and rupture feed raw materials. This process changes their physical and chemical properties. It also alters the feed’s structure and composition. Additionally, it increases starch solubility and improves protein digestibility and absorption. It further reduces anti-nutritional factors. These changes ultimately enhance the nutritional value of the feed.

This is a newly designed processing technology for improving the dog food, floating fish balls market, successfully developed with our many years of research experience in machinery. This dog food making machine gives pet food novel shapes, unique flavors and colors. It can meet other needs of the modern market through many superior features, such as scientific nutritional formula and easy assimilation. This kind of food-making machine can also make pet food with core fillings, which will be more popular with modern pets.

Application Areas

• Aquaculture: Production of floating fish feed (such as grass carp and sea bass) and shrimp/crab feed, with a floating rate of over 90%.
• Livestock and Poultry Farming: Adding expanded soybeans to pig feed can increase protein utilization by 18%.
• Pet Food: Extruded cat and dog food pellets have a crunchy texture, improving palatability by 30%.
• Specialty Feed: Feed for fur animals such as mink and foxes requires high-fiber extrusion processing.

A feed extruder usually consists of the following parts:

Feeding system: used to transport feed ingredients into the extruder, usually using a screw conveyor or vibrating feeder.

Puffing chamber: The puffing chamber is the core part of the puffing machine and consists of a spirally arranged extrusion roller and a cavity. The feed raw materials are puffed and expanded by high temperature, high pressure and screw extrusion in the expansion chamber.

Heating system: The pet pellet machine is equipped with a heating system to achieve the expansion process. It usually uses steam or electric heating to increase the temperature in the expansion chamber. This ensures that the feed raw materials are fully heated.

Discharging system: After the expansion process is completed, the expanded feed is discharged through the discharging system, usually through a vibrating discharge machine or conveyor belt.

The feed extruder plays an important role in the feed processing industry. It is especially suitable for processing animal feed for livestock and poultry. Through the puffing process, it significantly improves the taste and nutritional value of the feed. As a result, it increases animal growth rates and improves feed utilization. Moreover, it reduces feed waste and provides good economic benefits.
