According to www.hygienic-processing.de hygienic design refers to a design of parts, components and production plants that accounts for cleaning of the system, or even ensures cleaning ease. The cleaning requirements are considered in the structural design, and any spots where contamination can accumulate and pose a hazard to the product (e.g. pharmaceutical actives) are avoided.
In addition, efficient and safe cleaning of production plants presupposes that components are used that are easy to clean. Hygienic design is an important building block to ensure a high product quality.

When designing machines and plants under hygienic aspects, the materials and surface properties play an important role. The proper material choice ensures that reactions between the material, product and cleaning agents, etc., have no negative effects on the product. Proper surface finishing procedures support the cleaning ease and are thus key to the reduction of cleaning times, cycles and costs.
