Freeze-drying (also known as lyophilization) is a process of removing water or other solvents from a material through sublimation. Sublimation is the direct transition of water from the solid (ice) phase, to the gaseous (water vapor) phase, without passing through the liquid phase. This process preserves the structure and physical properties of the product.

We recommend to use a scroll dry (oil free) vacuum pump. Like our Anemos. Benefits to a the standard oil vacuum pump are; less noise, very easy and low maintenance, and last but not least no potential contamination of the processed product with the oil from the pump.

We have 4 options, 3, 5, 7 and 9 shelf’s, alle shelfs are heated and we supply supporting trays (12, 15 and 20mm hight).

That is R290 refrigerant.

Our machines control the process through the vacuum controller, witch is the most accrued way to control your Freezedrying processes.

We have a network of distributors with there own technical specialists and we have a 2 year warranty on our Xiros Mikro.
