What is the real procedure of freeze drying? and how costly the process will cost you?
Freeze drying is simply the removal of water from an item after it is completely frozen. It typically involves drastically decreasing temperatures of the initial object and then storing it in a vacuum for a period of time.
Because the item was still cold at the beginning of the process and drying can also eliminate heat from the product drying so the water contained in the original item will remain frozen throughout this entire procedure.
The process can be quite costly. Two things are required to accomplish this:
1.) A device to freeze the products. Most likely, a freezer that is -80C or the supplier of liquid nitrogen.
2.) A powerful vacuum chamber that is able to last for extended durations of time. (In terms of an efficient vacuum pump that is constantly working.) To achieve this, it is usually an additional support system that includes…
(Probably) (3) …An ever-on freeze coil in between an air chamber as well as the pump.
Each of these three items require lots of energy to run or even get going. That’s why the price is high.
