Tray height
The size of one tray of the dryer in height. In models where, instead of separate trays, a common working chamber with removable shelves is provided, the distance between two adjacent shelves is indicated.
This size primarily determines the thickness of individual pieces of vegetables, fruits, etc., which can be placed in the device. At the same time, note that the contents should not fill the tray tightly — there should be at least a couple of millimetres of space between the products and the “ceiling”. Also note that in some models, two height values can be indicated in this paragraph — for example, “15 — 25 mm”. This means that the size of the trays can be changed, adjusting them to the specifics of the situation; usually it is a choice between two standard heights (in our example — 15 mm and 25 mm).
Total capacity
The total volume of all dryer trays. The larger the volume, the more products can be loaded into the device at a time. For modern dryers, a capacity of
up to 10 L is considered relatively small,
from 11 to 15 L — medium,
from 16 to 20 L — high, and the largest models can hold
more than 20 L.
Note that if you plan to dry several different types of fruits or vegetables at the same time, it is worth considering not only the total volume of the dryer, but also the number of trays (see above).
