What Are The Raw Material Requirements For Puffed Feed?

                    Grinding particle size is very important to the extrusion and puffing process. Coarse material crushing particles will reduce the puffing coefficient of the product and easily block the mold; affect the pre-conditioning and extrusion mixing effects; cause great wear and tear on the extruder and high mechanical energy consumption; and will also make the appearance of the product particles rough. Therefore, it is necessary to determine the most economical crushing particle size based on product grade and extrusion requirements.

                    A reasonable but slightly higher starch content will increase the puffing coefficient and float rate; make the extrusion operation wider, making it easier to stabilize product quality; a slightly higher starch content will increase the flow performance of the material, which is beneficial to feed pelleting and contributes to Improve particle appearance quality. Better starch raw materials include high-gluten flour, corn flour and potato starch.
