The sequence of processing in the mixer is critical to achieving an optimal mix, and components must be added in the correct order. The standard rule goes from large to small and from dry to liquids.

Start with the macro ingredients, which are ordinarily pre-ground and blended in the milling process. Then mix in the minor and micro-ingredients such as minerals, vitamins, additives, and premixes. After the mix is achieved, liquids like molasses, amino acids, and fats are ready to be incorporated.

Vertical mixers are more adapted to small-scale plants or on-farm production. These systems leverage gravity to disperse the ingredients uniformly throughout the mix.

However, insufficient mixing time and an excessive production volume compromise the mix’s quality. In the best case, inadequate mixing forms agglomerates or lumps. In the worst case, it could raise the toxicity levels in the feed pellets.
