Can you tell me what the “large food dryer” is? Is that the same as a dehydrator?
Yes, a food dryer or dehydrator is the same thing. We have the Excalibur 3900. They are not cheap but it has easily paid for itself with the amount of yogurt and dried garden produce we’ve made. It works really well and is large enough to handle a lot at once. It can probably fit ten to twelve mason jars.
The only downsides are that it’s pretty large if you keep it on your counter and it looks like it was designed in the 1970s and never updated. 
And if so do you keep it at 110 then and for how long?
We go for 110 to 115 degrees for seven hours.
Another fun thing to try, which I did a couple of years ago was make cream cheese out of yogurt.
Technically it’s yogurt cheese, but it does have a similar consistency to cream cheese. It usually has a little bit of tartness that cream cheese doesn’t. It also has a lot less fat if you use low fat milk to make the yogurt. We like to use it to make herb spreads.
