What is freeze drying?
Freeze drying is like "suspended animation" for food. Freeze drying, technically known as lyophilisation, or cryodesiccation, is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.
Can we use whole or sections of the raw material?
Yes, as long as the material is prepared allowing it to fit onto the freeze drying trays.
What does it cost?
This really depends on the raw materials, the end yield and the customers needs. Due to years of experience we can assist by recommending various methods to keep the costs as reasonable as possible.
How long does it take?
Again, this depends on the materials and intentions. Typically the range may be 2-4 days to process 1 tonne of raw materials.
What about packaging and delivery?
FDI can do bulk packaging on site and arrange all transport needs either inwards or out.
How do you need to receive the produce?
The materials need to be prepared in accordance with our production quality control. This means the goods may be sliced, diced, destoned, crushed or in a puree form, and frozen.
Can you do vegetables?
Yes, vegetables perform very well to the freeze drying process.
