Production process of pet feed

06-02-2023

The pet food production line is a new type of pet food production line developed successfully by combining years of experience in the development of twin-screw extruder. The pet food production line endows pet food with novel shape, unique taste and color, and adapts to the developing pet food market with the most scientific nutrition ratio and easy digestion.


Over the years, the technical advantages achieved in the field of extruders are fully reflected in the pet food production line. The operation is simple and easy to learn, so as to ensure that the product is completed in a specific temperature, pressure, humidity and time. Reasonable structure design, special material, fast automatic cleaning performance ensure the stability of the machine and easy maintenance.

Extrusion is an important link in the processing of dog food. Extrusion is a kind of food processing method. It is to put the processed food into an airtight container, and then suddenly decompress after heating and pressurizing. The water in the food will vaporize and expand, making many small holes appear in the dog food, becoming brittle and become extruded dog food. The basic principle is to make the raw material suddenly decompress and expand under the condition of heating and pressure. As a new food processing technology, puffing technology began in 1910, and its application in pet food was in the United States in the 1950s. The United States first began to use extrusion technology to produce pet food, that is, to use the screw and screw sleeve in the puffer to warm and pressurize the raw material through extrusion, And extrude the high temperature and high pressure food out of the mold hole, and realize the process of rapid volume expansion due to sudden decompression.

The extrusion process is also a process of forming dog food raw materials. During the forming process, water is added in the form of steam to make the raw material starch in the dog food gelatinize, and the temperature rises to 100 ℃~180 ℃. Because the pressure before extrusion is very high, the pressure is released instantaneously during extrusion, which makes the dog food rapidly expand and foam, and the water evaporates. Therefore, the dog food processed by the extrusion process generally has high nutritional value that is easy to digest and absorb.

Advantages:


1. Improve the palatability of dog food. The dry dog food will become crisp after expansion. The pet dog will have a better taste and clean oral teeth during biting and swallowing;


2. Change and improve the nutritional value of dog food. Many nutrients need to be cooked and expanded before they can become nutritious. Otherwise, it will not bring effective nutrition to the pet dog, but will cause diarrhea, vomiting and other maladjustments;


3. Improve the digestion and absorption rate of dog food for pet dogs, and the expanded dog food for pet dogs is more comprehensive and complete. At present, there is even a "double expansion" process, which aims to make pet dogs absorb all the nutrients in dog food more perfectly;


4. The shape and structure of dog food are changed through the expansion and granulation process, which makes it easier for pet dogs to eat and eat more dog food;


5. Changing the content of different nutritional indicators of dog food, such as reducing water content, can improve the shelf life of dog food, and make it more convenient for pet owners to store and feed at any time and place, which is safe and convenient;


6. Changing the density of dog food, extrusion granulation and expansion can also increase the bulk density of dog food, which is convenient for purchase and transportation;
