6 Ways To Build A Food Dehydrator At Home - DIY Electric And Solar Dehydrator

It’s very likely that you’ve heard about food dehydrators. These units’ life-changing benefits are simply indispensable.

I’ve already written extensively on the best food dehydrators to buy on this site.

Do It Yourself

This article takes a different course though.

If you are an enthusiastic DIYer and you like saving some bucks on things that you can easily craft on a free afternoon, this article is yours!

Here, I’ll be sharing several tips on how to make a simple food dehydrator at home.

Types Of DIY (Do It Yourself) Food Dehydrators

There are a few reasons why you might want to make a food dehydrator rather than purchasing one; budget, hobby, and the desire to craft something.

Whatever your reasons, a home-made food dehydrator can either use solar or electricity. The former will definitely fit the bill if you are after saving money on power. It’s also the easiest to make.

Electric DIY food dehydrators, on the other hand, are a little bit technical to design and make. They also require power to operate. On the upside, they are fast and remain operational throughout the year whether there is solar or not.

Whichever the design that you opt to construct, ensure that:

  • It has ventilation to allow an easy and even airflow that circulates all over the food.
  • The trays are easy to remove or rotate for maximum drying capability and easy cleaning.
  • It is pest-proof. For solar food dryers, ensure that it can withstand the elements.

Also you can check our article on electric versus solar dehydrator and conclude for yourself which will be the right one for you.

Anyone who wants a food dehydrator definitely has cost-efficiency in mind. Nothing does that well than a metallic frame solar food dehydrator. The essence here is to construct a simple yet strong and effective model that will serve you for years.

4. Compact Solar Food Dryer

All the above solar food dehydrators have one thing in common: bulkiness. They might be quite hard to deal with in terms of storage especially if you live in tight quarters.

While they offer an enormous drying space, these models also require more materials and time.

If a compact yet effective food dehydrator is what you have in mind, the model below might meet your needs.

This dehydrators’ small footprint is its real advantage for people with minimal storage space. Moving it around is also quite easy thanks to its lightweight design.

On the flipside, it has minimal drying space and might take some time to dry enough food for a large family. You can, however, adjust the construction design to make it bigger.

Solar Panels

What You’ll Need:

  • 28-gauge metallic sheet (steel or aluminum)
  • Cedar wood
  • Corrugated galvanized metal roofing
  • A pack of exterior-grade wood screws
  • Clear polycarbonate sheet
  • Roofing screws with rubber washers
  • Food-grade stainless steel screen
  • Steel flat-head sheet-metal screws
  • 1 can black BBQ-grill spray paint
  • 3/8’’ stainless steel staples
  • Heavy duty galvanized T hinges
  • 1 tube squeezable silicone caulk
  • 1 5-inch Galvanized gate hasp
  • One 5″ galvanized gate hasp

A solar food dehydrator offers a cost-efficient way of extending the summer’s bounty of fruits and vegetables throughout the year without hiking your electricity bills. These models are easy to make and to use too.

They do come with a few drawbacks though. First, they are limited to the availability of sunlight. Thus, your fruits and vegetables might take quite some time to dry well. Secondly, it’s easy for the products to go bad in case there isn’t enough sun to complete the drying process.

On the same note, you’ll need to dry enough food in summer to take you throughout the rainy and sunless seasons.

If you want the freedom of dehydrating your food any time you wish, then an electric model might serve you better.
