Industrial freeze-drying technology
HADOF designs food, pet food, nutraceutical and life-science freeze dryers and complete lines — from material trial to pre-freezing, vacuum drying and moisture-protective packaging.
Start with the material
Initial moisture, piece size, sugar or acid content, and the final quality target drive the freezing method, the drying cycle and the line layout. HADOF sizes the dryer and its connected modules from those material questions, then confirms the result with a documented trial before capital is committed.

Each stage narrows the operating window and confirms the finished-product specification before you commit capital.
Applications
Each application is evaluated on its own material, quality targets and evidence — not on a generic machine description.
