Drying of food supplies was the most popular way to store them long time ago, when there were no conservation in glass jars. This method of storage has not lost its popularity and now, because maximum amounts of vitamins and minerals are stored in dried foods.
We had dried foods laying them in barns and other interesting places previously, now we can do it with an electric food dehydrator. Drying of medical plants can also be done with it.
Choosing of a food dehydrator for drying fruits, vegetables and more will be discussed below.
1. Type of food dehydrator machine.
We need to determine the food dehydrator type first. There are two main types of dehydrators: infrared and convection.
Infrared food dehydrator makes the drying process using infrared radiation. This type of drying is considered the most perspective now.
Infrared rays transfer heat directly to the water component of the product, therefore drying can be carried out at relatively low temperatures (under 60 degrees). Infrared drying of fruits and vegetables allows keeping nutrients almost completely.
Convection dehydrator makes drying with hot air. The whole product is gradually heated from external to internal layers during this process, not only its water component.
I think the benefits of infrared dehydrator are obvious. However, convection dehydrator also has its advantages, the most important of which is lower price.
2. Food dehydrator electric power.
Power of electric dehydrator, as power of any electrical device, measured in watts. Big power helps you to dry foods more quickly.
Dehydrators power ranges from 250 to 600 W on average. It is better to choose a food dehydrator model with 360-450 watts power for home use.
3. Swept volume.
Amount of foods that you can to dry at one time depends on swept volume of dehydrator. Swept volume depends on the number of pallets (sections) in which you can put products. You can dry more products if there are more pallets in dehydrator.
From 3 to 8 pallets may be in the food dehydrator. There are 5 pallets there most commonly.
Size of these pallets is also important. Circular pallets have a 32-33 cm diameter very often.
Pallets can be transparent or not. You can visually monitor the drying process using transparent pallets.
4. Case Material.
Dehydrator case can be made of plastic or metal. The plastic case is more convenient for household use because it is more lightweight. Also, plastic is less overheating during drying. Most cases of home kitchen dehydrators are made of plastic.
5. Protection against overheating.
The drying process requires high temperatures, and it requires a possibility of automatic device shutdown in case of overheating. Auto shutdown is a very necessary function that helps you to avoid troubles.
You also need to pay attention to user control panel when buying dehydrator. The control can be electronically (by using the buttons and electronic display panel) or mechanically (by using of simple regulators).
In general it can be noted that the good food dehydrator, as a steam cooker, refers to devices which help to make our food more healthful.
Now you learned in detail the characteristics and parameters of dehydrators and you can decide which dehydrator for fruits and vegetables will suit you best.
