Food dehydrator. Equi-Flow Brand. My Mother purchased it in the 1980s. I am sure the company is no longer in business. Has 10 plastic trays approximately 14 x14 inches all in good condition. We have used it numerous times over the years to dry mushrooms, herbs and fruit. My husband had to rewire it at one point. It works fine. Throws off a lot of heat, might be best used outside or in a garage in warm weather. It is too big and cumbersome for me these days. The outer shell might be particle board with a paper cover on the outside (like contact paper) and some off that paper is lifting away. 18 inches long, 15 inches high and wide.
