Extrusora de Ração para Animais de Estimação

The pet food extruder is a specialized equipment designed for the production of pet food. It utilizes high temperature and high pressure conditions to induce puffing in the raw materials used for pet food. In this process, moisture within the raw materials evaporates, causing volumetric expansion and the formation of a porous structure. This results in the final pet food being more easily chewed and absorbed by pets.
Puffing Process:
1. Heating: The raw materials are heated to high temperatures, typically using methods such as steam or electric heating.
2. High Pressure: Simultaneously with heating, high pressure is applied through screws to subject the material to high-temperature and high-pressure conditions.
3. Sudden Release: At a specific moment, the material experiencing high temperature and pressure is rapidly released into an environment with lower pressure.
4. Puffing:The rapid release causes moisture to evaporate, leading to the puffing effect where the material expands in volume, forming the puffed product.
This puffing machine is crucial in the pet food industry as it enhances the palatability and digestibility of the final pet food products. The puffing machine plays a key role in producing pet treats, kibble, and other forms of pet food with improved texture and nutritional characteristics.

1. The series of extrusion puffing machines are mainly composed of a feeding system, sistema de extrusão, sistema de corte, sistema de aquecimento, lubrication system, e sistema de controle.
2.The feeding system, main drive system, and cutting system of the extruder adopt variable frequency speed control, providing strong power, smooth operation and low energy consumption.
3.Automatic lubrication and forced cooling ensure the safe operation and extended lifespan of the extruder.
4.The screws are made of alloy materials and undergo special processing, resulting in high strength, wear resistance, and a long service life.
5.Different screw extrusion systems with varied structures and length-to-diameter ratios are available to meet the process requirements for different products.

The pet food extruder is primarily used for producing various shapes and flavors of pet food, including but not limited to pet treats and granular pet food. In the pet food industry, the application of puffing machines contributes to enhancing the texture and palatability of pet food while also improving the nutritional absorption of the products. In the food industry, it is commonly employed for puffing grains, legumes, starch, etc., to manufacture a variety of puffed foods such as puffed grain breakfast cereals and puffed corn flakes.
