I put 5 pounds of beef to dry, expecting it to take at least a day. 5 hours later and it was done! And Let me tell you, those beef slices were not paper thin. Thin apple slice be able to take flanked by 12 and 18 hours to acquire a tough texture.

Not a lone banana or one other fruit akin to apples get stuck in the trays toward the point that they couldn’t be uninvolved easily through the fingers.

The power consumption was very good but it does vary from start to finish. This is because the original hours take extra power as the machine is heat the trays so the thermostat rarely turns off. subsequent to a few hours, the thermostat only activate irregularly to liven up the heat, agreed that the trays are by at the moment heated and simply need upholding to be the warm air flow.

Using the mesh actually has helped me to determine when my food is completely dehydrated. If the food it still sticking to the mesh, I know I need to leave it in there longer. When it is peeling off of the tray, it is easier to get off of it and normally the food is completely dehydrated.The machine handles an array of food from strawberries, bananas, a variety of peppers, potatoes, meats and even bread. Bananas took nine hours to dehydrate,with peppers only taking four and a half hours to become complete. Meat times varied with chicken taking between 12-15 hours and beef between 8-12 hours.

It comes with a clear door so you can see inside to check on the food. It has a digital display with eight different preset temperatures, though I find using the highest temperature of 158 the most effective. You can the time on it in 30 minute increments, but there's no harm in setting a higher time only to turn it off when the food is done. It has 360 air flow from the fan in the back and the one in the top. Perhaps the most impressive part though is that it never gets too hot to touch.That feature will certainly make a mom happy.
