Currently freeze drying can require a 22-24 hours drying cycle, and must be loaded and unloaded by hand. Both these factors can inhibit large-scale producers looking to push out more product. This technology relates to a dryer and a drying process developed to enhance efficiency in the freeze drying process.In particular, though not solely, this technology relates to a dryer for use in freezing, concentrating or drying a liquid substance which has some solid material in suspension or a substance dissolved in another liquid. This new technique dramatically reduces processing times and can be used as a continuous process, thereby increasing throughput and efficiency.

Key Benefits

  • Increases efficiency of the spray freeze drying process
  • Allows for continuous flow processing and hence higher throughput
  • The higher throughput allows for more material to be dried in the same time as conventional machines

Target Applications

This technology provides a new method of freeze drying liquid materials where the material to be frozen is first atomized and frozen, and then dried at reduced temperature.It can be used in any situation where spray freeze drying is used or where large volumes of material in a liquid phase need to be dried, i.e. milk, coffee etc.

Target Cooperation Model

  • Nonexclusive Licensing
  • Exclusive Licensing
  • Early Adoption
