Products are batched according to recipes that may contain between 15 to 60 raw materials, including vitamins, minerals, enzymes, RNA/DNA tissue factors, amino acids, and botanicals. Materials are reduced to the desired particle size in a hammer mill, transported in 44-gal (194 l) lined food-handling containers, and then gravity fed into the Rotary Batch Mixer, a 40 cuft (1132 l) model 700-TS-40-SS from Munson Machinery.
