Tray size

Horizontal dimensions of one dryer tray.

For round models, this paragraph usually indicates the diameter (for example, “Ø250”), for other cases — the length and width. Anyway, the information about the size allows you to estimate the total area and, accordingly, the capacity of the device. At the same time, note that a larger size affects the dimensions and weight of the structure, and also requires more heating power (ceteris paribus).

Temperature range

The temperature range that the dryer can provide in the working chamber.

The simplest models provide only one operating temperature option, usually from 50 °C to 60 °C. More advanced devices equipped with thermostats (see above) and can have a wide range of adjustment — this is very useful, because different temperature regimes are recommended for different products. To assess the general capabilities of a particular dryer, you can use the following table of temperatures recommended for drying:

— 35...40 °C — plant stems, greens;
— 40...45 °C — bread;
— 38...42 °C (in some cases up to 45 °C) — yoghurt;
— 50...55 °C — vegetables;
— 55...60 °C — fruits;
— 65...75 °C — meat, fish.

We emphasize that these are the most general, conditional data. The specific temperature may differ from the recommended one — depending on the thickness of the slices, the specific type of food, the desired result, etc. Detailed recommendations on this matter can be found in special sources.

Control

The control panel of a fruit dehydrators.

— Control knob. Mechanical control is carried out using rotary knobs and switches. Most parameters in such devices are set and controlled manually. In this case, the control elements are connected to the working parts of the dryer directly, without additional electronic circuits. This option is simple, reliable and low cost; however, it is only suitable for the most basic functions, but dehydrators for fruits, vegetables and mushrooms usually do not require more. But the obvious disadvantage of mechanical control is low accuracy: for example, a mechanical timer most often gives an error of a couple of minutes, which in some cases can be critical.

Push-button. Push-button control is based on electronic circuits. Such systems are more accurate than mechanical ones (for example, the timer in such dryers can usually be set with an accuracy of several seconds), and more options and modes are provided. On the other hand, such control is more complex and more expensive than mechanical control.

Touch. A type of electronic control with touch switches. Compared to push-button models, it provides a high level of comfort in operation, and looks more modern and aesthetically pleasing. Touch control is found mainly in top models of dehydrators.

Overheat protection

Security system that turns off the power to the dryer when the critical temperature in the working chambers is reached. This does not only save food from overdrying, but also prevents more serious consequences in the first place, such as a breakdown or even an ignition in the dryer, which is fraught with fire.
