When making sinking puffed feed, fill the modulator with water (no or little steam). The ring mold should have 26 ~ 30 atmospheres (25 ~ 29kg / cm2). The rear bulk density is 450 ~ 550g / L, the temperature is 120%, and the moisture is 26%.

2.1 Physical and chemical characteristics of raw materials, raw material pretreatment and formula ingredients will affect the processing quality of extruded materials. Specifically, the raw material puffing quality coefficient affects the feed puffing effect and puffing cost. Whether the material is removed from impurities, whether the particle size is up to standard, or whether the pre-conditioning treatment is performed will affect the pafing effect.

2. Reasonable starch content. A slightly higher starch content will increase the swelling coefficient and increase the water floating rate. It will increase the width of the extrusion operation and stabilize the product quality. A slightly higher starch content will increase the flowability of the material, which will help feed pelleting. , Help to improve the quality of particle lukluk i olsem .

Therefore, when the total fat content of the extruded floating feed is more than 8% before extrusion, the excess oil should be sprayed outside to reduce the impact on the extrusion process. It has been proved by production practice that high-fat raw materials are conducive to improving the level of grease.
