Not only does it spread the cost, but it can also increase the amount and variety of the preserved food you store away. Additionally, a group purchase can also lead to purchasing bulk quantities of food to freeze dry.

Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?

Is it flash freezing and dehydrating at the same time? Do the items need to be kept frozen, or stored at room temp?

The highly-skilled team at Toronto Refrigeration can cover all of these items, and more – even something as complex as a microwave can be salvaged, so you don’t have to buy a new one and dispose of the old unit in an already crowded landfill.

Presumably you have one of the medium sized units that is used for dried flowers, taxidermy etc - those are most common on the market. Lab supply places have very small ones for scientific samples. Food oriented freeze dryers tend to be factory sized.

Have an understanding of which kind of food pretreatment is needed to use the device. To ensure the freeze-drying approach is productive, you’ll must understand how to get ready food.
