In the market of baby food or powdered milk, in order to meet the stringent product quality standards, the latest knowledge of high hygiene standards and the technology to mix components of a very small quantity with high reproducibility are required.

Various components of different bulk densities and flowability, such as vitamins, salts, metal complexes, and amino acids in small quantities, have to be precisely mixed for infant milk production.

In the market of infant milk, the requirements for mixing precision are similar to those of pharmaceutical products. Active ingredients are mixed with care depending on the maximum recommended intake. The most important thing is to guarantee that infants can take the nutrients precisely when powdered milk is dissolved in water. For infant milk, the amount of each nutrient serves as the quality standard. It is too expensive to analyze each small batch. In order to reduce the analysis cost of active ingredients, it is required to prepare large-batch production of at least several tons. To fulfill the requirements for large processing volume and precise mixing, Hosokawa proposes a mixer with a cantilevered screw of sanitary design, a large door for cleaning, a sanitary sample bin, and a Hosokawa Isem valve of sanitary design.
