Within this category an overview is made of all technologies used to remove water from a (wet) product flow. Purpose of the drying process is usually to reduce the water activity so shelf life is extended. Drying is a specific form of separation technology (see Separation & Extraction).

List ofknown novel technologies

  1. IQD (individual quick drying) drying
  2. Radiofrequent, Microwave en Infrarood drying
  3. Superheated steam or SHS dryers
  4. Sorption dryers with zeolite
