Characteristics of Preconditioning Technology for Dog Feed Extrusion Machinery

Yesterday's article discussed the differences between wet and dry extrusion machinery for feed. In the wet extrusion process for dog food, pre-conditioning technology plays a very important role:

1. Improve extrusion granulation capacity. By pre-treating the raw materials and preheating them with steam, the raw materials are softened, making them easier to shape, while reducing wear on the screw, significantly lowering the frequency of screw replacement.

2. Increase particle density through pre-conditioning technology, reduce dust rate, minimize raw material loss during dog food processing, maintain a hygienic production environment, reduce dust pollution, and improve environmental cleanliness; 3. Promote starch gelatinization and protein denaturation, improving pets' digestion and absorption of food. Results show that the starch gelatinization rate can reach 35% to 45%, while without steam pre-treatment, it is only about 15%. The increase in starch gelatinization rate effectively enhances pets' ability to digest and absorb feed, which is more beneficial for pet growth.

4. More thorough elimination of harmful bacteria: high-temperature steam can kill most E. coli and Salmonella during the pre-conditioning process, greatly improving the safety and hygiene standards of pet food and dog food, making pets less prone to diarrhea and keeping them healthy. 5. Using conditioning technology, it facilitates the addition of liquid nutrients, improving the nutrition of pet food. Various vitamins and nutrients can be added to enhance the nutritional content of the feed.

The application of pre-conditioning technology in dog feed production lines varies across different configurations of pet feed production lines. The choice depends on the customer's subjective and objective conditions. You can consult our company at any time, and we will provide relatively impartial recommendations.
