The Process of Freeze-Drying
Solidify drying is a mind boggling procedure of safeguarding new or officially cooked sustenance by evacuating up to 98% of the nourishment's dampness, leaving in place the sustenance's composition, flavor, smell and wholesome worth.
The procedure requires that the crisp or cooked nourishment be immediately solidified at temperatures as low as - 50°C. The solidified nourishment is then set into a vacuum chamber. This vacuum chamber brings down the weight, and raises the temperature to pretty much 0°C.
At this particular temperature and weight, the ice gems in the nourishment vanish into water vapor, bypassing water's fluid structure, through a procedure called sublimation.
