Generally, the horizontal ribbon spiral mixer mixes for 2 to 6 minutes per batch, while the vertical mixer needs to mix for 15 to 20 minutes. Note that the mixing time should not be too short or too long. However, it does not mean that the longer the mixing time, the better the mixing effect. In the mixing process of materials, mixing and separation are carried out simultaneously. Once the mixing and separation effects reach a certain equilibrium state, the degree of mixing is determined. Even if the mixing continues, the mixing effect cannot be improved. On the contrary, separation will occur due to excessive mixing.

Changes in the granulation process During the granulation process, the temperature of the feed is increased due to the pressing effect, or the feed is kept at high temperature for too long due to steam heating before pressing. High temperature has some good effects on crude fiber and starch in the feed, but it has adverse effects on heat-resistant nutrients such as vitamins, antibiotics, and synthetic amino acids. Therefore, the proportion of heat-resistant nutrients should be appropriately increased in the formula of pellet feed to make up for the loss.
For fixed container mixers, the mixer should be started before adding materials to prevent full-load startup, and the machine can only be stopped after all materials are unloaded. For rotating container mixers, materials should be added before starting, and the machine should be stopped before unloading. For V-type mixers, materials should be added from two feed ports respectively.
