When we’ll convert them to calories then result will shock us, 1 in 4 calories are being wasted so in another words, we are not consuming them properly.

We can observe various reasons for food wasting some of them are controllable and rests are uncontrollable. We can manage controllable facts only.

Basically, this process is used to preserve food without using any chemicals and keeping same pattern its food structure. It works through freezing the product and reduction the pressure surrounds it. It causes the water to become frozen move from the solid state in which it becomes gas.

This process was processing in a machine named as food dryer. The process starts from chopped fruits or vegetables. The chopped pieces keep into a big cavity where freezing of the product is done and at the same time water or moisture has been soaked out by vacuum pumps. After this process, allows heat to speed of sublimation process. Then condensation process starts where vaporized solvent removed from the chamber. As this process is over, the separation process of water from the product have been completed.

So to perform this overall process, sophisticated equipments are required which will make this job easy. Middle sized freeze dryer is one of them. It uses radiation mode for heating in which first trays are placed accordingly and placed them in to the chamber because it should be clear that no direct contact among them. This radiation mode is much suitable for the loose vegetables, fruits and slices.

If this machine is short for you then you can assemble larger one. These are larger in size placed in separate room and the large number of trays needs to move by rails. High quality machines are able to make a good output for this reason you need to choose them according to your needs.
