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).
Power consumption
Rated power consumed by the dryer during operation.
This parameter is usually selected by manufacturers depending on the volume of the dryer: the larger the device, the more power is needed to effectively heat the working chamber. At the same time, models with the same volume may differ in power consumption. In such cases, it is worth considering that a higher power reduces the heating time, but affects the price of the device.
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.
