My dehydrator has been running day and night for months now. I needed a better way too dry the green beans because we had been getting at least 16 gallons a weeks for weeks and I needed the dehydrator for other things. I found this idea on the web and it works great:
That is the old time name for dried green beans that are made by using a needle and string or heavy thread to string the beans on. First you must blanch the beans for 3 minutes and then in ice water for three minutes. Drain and string with needle to make a bunch. Hang somewhere warm and dry. It will take about 4 days and you have great dried green beans to store in jars or bags.
