I recently bought my food dehydrator, now can't find the instructions, but have relied on infomation from neighbour who also has one, but after 26 hours, I am still drying my grapes, they are a very old variety, we know this from some of the locals in the area, it is like a muscatel, I would also like to know how much power it uses per hour, . Alos how do I store the tomatoes once they are dried. Many thanks, Michelle.
