I've only had mine 6 months or so and all I make is beef jerky lol I'm an addict :P. How long depends on what kind of meet you're using and how thin it is. I usually make ground beef jerky and usually takes around 5 hours I think. I got the book out to look at fruit and vegetable times for you but they're all different. the min time on the different veggies range between 3-6 hours and the max time is 10-20 depending on the vegetable you're drying. fruits 3-18 min 8-16 max. If you have certain fruits and vegetables in mind I can look them up for you
