Vegetable Dryer Do Miniature Seed Dryers Exist?

Do miniature seed dryers exist? - vegetable dryer

My dad loves gardening and is always trying to save seeds from vegetables, dry them, and would reuse them, but do not seem to always be able to do it when my boyfriend said to be the perfect Christmas gift a dry seed. I, know it, but I saw online are enormous and it is certainly not a garden near big enough to need one of these. I never talk of a dry seeds before my friend could hear. I was hoping that someone out there knew of any small size, which is cheaper. Thanks in advance!
