Electric dryer from scrap materials

Spring is approaching, and this, as you know, is the most suitable time for collecting medicinal herbs. It is at this time that all the most useful substances are concentrated in them. And here's one caveat: the faster you dry these herbs, the more benefit they will be. But it is undesirable to do this in the oven, because the high temperature does not always have a beneficial effect on the medicinal material. It is optimal to dry in a room at room temperature, but with constant air movement. The task is not easy, which can be solved with the help of electric dryers. Such a device costs from 3,000 rubles, in addition, it takes up quite a lot of space. Not every housewife will find an extra shelf in the kitchen for storing such a gadget and wants to buy a device for drying a basket of mushrooms or a handful of thyme. But you can make a rather effective dryer with your own hands from an ordinary cardboard box, and it will cost you 300 rubles maximum. Adopt the experience of a YouTube channel creator Musiy4uk - and you will definitely not regret it.

What is required to make an electric dryer

So, the conversation will be about the use of scrap materials, which means that the cost of the entire product will be minimal.

You will need a tall cardboard box. The size in this case is of little importance, but do not take too large a volume.
Another important detail is a computer cooler, a fan that cools the contents of the system unit. It costs about 150 rubles, and you can buy one in any store with electrical appliances, if you suddenly didn’t have a used one.

In addition, you will need a 50-70 ohm resistor and a 12-volt power supply.

So, the main principle of the future dryer will be based on a fan placed inside it.

Start by gluing the fan to the bottom of the box. The best way to do this is with hot melt glue. Apply a few drops to the body of the device and just place it in the boxPHOTO: YouTube.com

How and what to make a drying platform

Let's start by solving the question of how to keep the platform at a safe distance from a running fan.

And now about the drying platform. The easiest way to make this platform is from the same cardboard, but there is one caveat: from the natural moisture of the materials that you will dry, the cardboard is deformed and saturated with unnecessary odors. What can be used in this case?

A very simple way out is a piece of thin foam, ceiling tiles. Cut out a suitable piece and pierce it in several placesPHOTO: YouTube.com

Instead of styrofoam, you can use a hard plastic folder cover. Holes in it can be made with a soldering iron sting or a knitting needle heated over a fire. If you can find a suitable size, fine mesh grill is also a good option.

All that remains is to place your platform in the box and use the dryer for its intended purpose.PHOTO: YouTube.com

Place your material on the platform and turn on the fan. Such a dryer consumes minimal energy, works for an infinitely long time and very carefully dries everything that appears on the platform: it can be mushroom plates, like cut vegetables and, of course, herbsPHOTO: YouTube.com

Yes, the task is not an easy one, and it will take you some time to assemble the entire structure, but the effort is definitely worth it. If you need to dry more food, multiple fans can be used. You can even make a fish dryer according to the same principle. In a cardboard container, flies will not attack it if you close the box with a net or a piece of tulle. Put such a device on the balcony - and the fish will dry up in a couple of days. In short, the idea is very successful, and it is worth taking it into service.
