You can make a lot of delicious and healthy snacks using this technique, for example by drying all kinds of fruits and vegetables. So, if you want to try it out at home, we recommend that you build your own homemade solar dehydrator.
Dehydrated fruits it is a healthy option for those who love sweets and fruits. These fruits also contain sugar, but they are not as bad as the refined sugar that we normally consume.
Natural preservation methods are essential to prolong the life of the fruits and vegetables produced during the summer harvest. A great way to get rid of excess production in your garden or save money by purchasing and keeping fruit in season.
Those that run on electricity are expensive, solar dehydrators are cheap and efficient. There are many possibilities for building your own solar dehydrator. In the next tutorial, we’ll 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 trash. You can customize it according to your preferences and the material you have. A great and useful tutorial.
Why dry fruits and vegetables? We remove 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 suggest the one in the image, but be careful that there are hidden holes in this image. The darker section is a piece of heat absorbing material, we used painted metal for this particular dehydrator, but you can use equivalent material. The food is placed on the shelf, with a fabric screen on the outside. The rear 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.
- Wood suitable for the legs.
- Appropriate transparent plastic window or slab.
- Screen (to cover the vents).
- Stockings or equivalent textile material for the dryer.
- 2 hinges.
- A hook and a 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 ″ ‘(high)
- TWO of 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 cut to fit the legs and vents.
- 14 1/8 “x 23 1/16” hinges (rear).
Step 4. Assemble the frame.
Build the first base as in the picture. Attach side pieces of plywood to the legs. Lay the piece of wood for the following layers. Secure the top piece.
Step 5. Additional components.
Put the absorbent material on the shelf, stapled. Cut and secure the drying screen support piece. Repair the window. Cover the holes with the screen material to protect against insects. Place the thermometer indoors near the drying rack.
Step 6. Dehydration. Advice.
Dehydration occurs by removing water from the fruit, it prevents the proliferation of bacteria and mold, it is a simple method that with little work maintains the nutrients of the fruit better than preserves or preserves.
Drying occurs when the internal temperature is between 38 and 60 ºC. With less temperature, bacteria can proliferate. With a higher temperature, the food cooks. We need to control the temperature. Each food has an ideal dehydration temperature, experience will guide you in this regard.
After the process is complete, you need to store the dehydrated food in airtight containers, vacuum is possible and you will not consume it on the following days, in a dry and dark place.
