Like hiwall mentioned above, dehydrators are relatively inexpensive. They can often be found in thrift stores or at garage sales for less than $10. Even a large top-of-the-line like Excalibur is around $200.I’d love to pick up a dehydrator some day and get started. Are they expensive?
A freeze dryer, on the other hand, is substantially more expensive, $2,200-$4,500, depending on the size and oil pump you choose.
You can process more food in a dehydrator than in a freeze dryer in the same amount of time. However, you can do things in a freeze dryer that just don't work in a dehydrator. Foods like cheese, eggs, bacon, sour cream, cream cheese, avocados, etc.
