How to Build a Portable Electric Food Dehydrator

Make a simple food dehydrator to dry fruits.

Building your own portable electric food dehydrator is less expensive then purchasing a manufactured one. Complex models can be difficult to make and require a great amount of skill and time. However, a simple food dehydrator can be made quickly and easily, without any special tools or equipment. The portable food dehydrator is perfect for small spaces and easy storage.

Things You'll Need

• Shallow, lightweight baking sheet or disposable aluminum baking pan
• Black permanent marker
• Cardboard box
• Aluminum foil
• Long-life light bulb
• Porcelain lamp socket

Instructions

1. Color the underside of the baking sheet with black permanent marker. This will serve as the drying tray. Measure the length and width of the drying tray and choose a cardboard box that is slightly smaller or equal to the size of the baking pan.

2. Remove the flaps or lid from the cardboard box. Line the inside of the box with aluminum foil. Place the foil so it lays flat on the bottom, flush against all four sides and drapes 1 inch over the edges.

3. Screw the light bulb into the porcelain socket. Place the light bulb and socket in the center of the aluminum foil box. Use fire-retardant materials, such as electrical tape, to prop up the light bulb so only the socket is touching the box. To prevent a fire hazard, the light bulb should not touch any part of the box. Hang the cord outside the box by draping it over one of the corners.

4. Place the box in a heat-safe, sturdy location near an electrical outlet. Set the drying tray on top of the box. Place food in a single layer on the tray and plug in the light bulb when ready to use.

Tips & Warnings

• Only use the food dehydrator on a heat-resistant surface, such as a kitchen counter. When using in other areas, place the food dehydrator on a hot pad or on trivets to reduce the risk of fire.

• Do not leave the food dehydrator unattended when in use. Check to ensure the light bulb remains propped up and is not touching the cardboard.

• Do not use electric food dehydrator outside. It is intended for indoor use only and should not be used in or near water.

• Immediately unplug the light bulb if smoke appears or any surface becomes exceedingly hot.

• Children should be supervised when using the electric food dehydrator.
