This is the Excalibur dehydrator that I use to put away a lot of garden produce. You can use a dehydrator to turn low-carb veggies (like zucchini) into a crispy snack. It's hard to find low-carb crispy 'chips' to go with dips, but this will do the trick. This 9-tray model is really big - I can fit 15 pounds of tomatoes or 2 small watermelons in it. If you're not concerned about putting away a lot of produce at once, then you might be fine with a smaller model.
