If you like dehydrated food, surely you would like to know how to make it at home. Drying food can be very useful, as it will help you preserve it for longer.
You can make a lot of delicious and healthy snacks using this technique, for example drying all kinds of fruits and vegetables. So if you want to try it at home, we recommend that you build your own homemade solar dehydrator.
Dried fruit is a healthy option for those who like sweets and fruit. These fruits contain sugar as well, but they are not as harmful as the refined sugar we normally consume.
Natural preservation methods are key to extending the time of the fruits and vegetables that are produced in the summer harvest. A great way to get rid of excess production in your garden or to save money buying and preserving fruit in season.
Those that run on electricity are expensive, solar dehydrators are cheap and efficient. There are tons of possibilities to build your own solar dehydrator. In the next tutorial we will teach you how to make your own solar food dehydrator from recycled materials, an old ladder, a window, and other materials that could be considered garbage. You can customize it based on your preferences and the material you have. A great and useful tutorial.
Why dry fruits and vegetables? We eliminate moisture and thus prevent bacteria from killing fruits and vegetables. Drying is a form of preservation.
Instructions for making a food dehydrator.
Step 1. Design.
Choose the right design to minimize errors …
We propose the one in the image, but be careful that there are holes that are hidden in that image. The darkest section is a piece of heat absorbent material, we used painted metal for this particular dehydrator, but you can use an equivalent material. The food is placed on the shelf, with a cloth screen on the outside. The back piece of wood can be opened to remove the shelf and provide additional ventilation.
Step 2: Materials.
- Fine wood for the body of the dehydrator.
- Suitable wood for the legs.
- Window or suitable clear plastic slab.
- Screen (to cover the vents).
- Stockings or equivalent textile material for the drying rack.
- 2 hinges.
- A hook and chain (to hold the tailgate).
- Sealer (for perfectionists).
Step 3. Cut the pieces to the correct size.
Checklist for plywood parts:
- 1 ′ x 23 1/4 ″ ‘(top)
- TWO 20 “x 12” x 26 1/8 “x 14 1/8” (sides) have a diagonal cut.
- 26 1/8 “x 23 1/16” (bottom) will be trimmed to fit the legs and vents.
- 14 1/8 “x 23 1/16” (rear) hinges.
Step 4. Assemble the frame.
Build the first base as in the image. Attach side pieces of plywood for the legs. Lay the piece of wood for the subsequent layers. Fix the top piece.
Step 5. Additional components.
Put the absorbent material on the shelf, stapled. Cut and secure the support piece for the drying screen. Fix the window. Cover the holes with the screen material to protect from insects. Place the thermometer indoors near the drying screen rack.
Step 6. Dehydration. Tips.
Dehydration occurs by removing the water from the fruit, it prevents the proliferation of bacteria and molds, it is a simple method that with little work maintains the nutrients of the fruits better than preserves or preserves.
Desiccation occurs when the internal temperature is between 38 and 60 ºC. With less temperature, bacteria can proliferate. With higher temperature, food cooks. We must control the temperature. Each food has an ideal dehydration temperature, experience will guide you in this regard.
Once the process is finished, you must store the dehydrated food in airtight containers, vacuum is possible and you will not consume them in the following days, in a dry and dark place.
