Industrial food dryer oven machine mango fruit vacuum drying machine
BSVD vacuum dryer works under vacuum condition. Under such condition, the boiling point of material solution will reduce. It will increase impetus for heat and mass exchange. So it is very suitable for materials that are easy to oxidation and easy to decompose during the drying process. For example, fruit and leaf.
Working method:
Pure water has the maximum vaporization rate when it is boiling. Under normal pressure, pure water starts to boil at about 100°C. Under vacuum conditions, because the partial pressure of water vapor in the system is much lower than that on the surface of the material, the boiling point of water is lower than 100°C. For example, when the surface drops to -0.07Mpa, the water starts to boil at 70°C. General rule: the higher the vacuum, the lower the boiling point of water. In the vacuum dryer, the vaporized water can be quickly removed with the vacuum generation, so despite the lower operating temperature, the dryer still has a large drying capacity.
Main features:
1. High drying capacity and fully use of heat energy.
2. It is suitable for materials such as heat sensitive and easy oxidizable material.
3. It can dry raw materials that contain solvent and which needs to be recovered.
4. Undamaged quality of the materials after drying because of the way of static drying.
