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.

Shutdown timer

A special device that turns off the heating after a predetermined time.

The presence of a timer greatly simplifies the use of the device: instead of monitoring the duration of the process and manually turning off the heater, it is enough to set the desired turn-off time in the settings. In addition, this function reduces the risk of forgetting about drying products and “overexposing” them in the dryer: this can only happen if the timer was initially set for too long.

Note that the type of timer directly depends on the type of control (see above); at the same time, mechanical timers are simple and inexpensive, but they have a rather noticeable error, and electronic ones are very accurate, but they cost accordingly more.
