    Introduction to Freeze Drying Lemons

    What is Freeze Drying?

    Traditionally we eat food because it spoils. We are creatures who walk around yet need to eat every day. The best way to stop food rotting is freezing. But rather than just freezing it, we can also dehydrate it in something called a freeze drier or, to use its proper name, a lyophiliser. A lyophiliser freezes the food, then sucks out the surrounding air and lowers the pressure as far as possible. The food is no longer heavy so it cannot fall, and seals against the cold in a heavy cloak. Once the freezer door is closed, everything remains still. When all the air has been removed, the ice in the food sublimes into water vapour. What is left is lightweight food that will keep indefinitely – a great invention to extend perishable foods indefinitely.

    After the lemons are frozen, the freeze dryer reduces the pressure inside the chamber. This is phase two, also called the primary drying phase.
