TRAY DRYERS

What are tray dryers?

Tray dryers are also known as vacuum drying ovens. These are a type of chamber dryer that dry temperature-sensitive materials at lower temperatures.
The vacuum generated in the chamber reduces the boiling point of the liquid to be evaporated. So that, for example, water can be evaporated, depending on the achieved vacuum pressure, at temperatures well below 100°C.
Depending on the material to be dried, vacuum drying ovens may be designed differently inside

What are freeze dryers?

Freeze dryers are a special form of vacuum drying ovens. A free dryer (lylophilizer) are used for freeze drying. The goods to be dried are quickly brought into a frozen state, after which the water is removed by sublimation.
The water passes directly from the solid state (ice) in the evaporated state. This drying method is very gentle on the product, so that, for example, organic cell walls, vitamins, flavors and the natural color are largely retained.
