You would be able to store more food while taking up less space compared to freeze dried products. Dehydration can reduce the size of a product up to 50% which for food storage this is ideal. Size of finished product is another place where these two machines differ as dehydrated foods have a much larger size reduction of finished product compared to a freeze dried product.Both methods will extend shelf life but comparatively you are left with two very different products. But with a dehydrator when you dehydrate meat you will be left with jerky that is ready to eat. So if you freeze dry meat you will be left with a product that once rehydrated will still be raw meat. Whereas with dehydration you are creating a new product. Freeze drying is generally quite crunchy whereas dehydrating can give you a chewy or crispy texture depending on how much moisture is removed which can be controlled by how long you leave your product in the dehydrator. Another thing to remember is that when you freeze dry meat, what you are basically doing is putting a stop to the aging process. It’s important to remember that when stored correctly, freeze drying and dehydration are both great options for long term storage and preserving foods. This is because the moisture level with freeze drying is brought down to about 5%, with dehydrating generally being closer to 10-15%. Freeze dried products can have a shelf life of up to 20-25 years, whereas the shelf life of dehydrated foods is more around the 5-15 year mark. The main difference between freeze drying and dehydrating is the shelf life of the finished product and the consistency of the finished product. However, there are a few key differences between the two methods. Both freeze drying and dehydrating are effective ways of preserving food by removing moisture and therefore preventing decomposition or the growth of bacteria.Freeze Dryer (Left), Dehydrator (Right) WHAT’S THE DIFFERENCE BETWEEN FREEZE DRIED AND DEHYDRATED?
