Comparison VINIS VFD-710BX vs DEX DFD-515S

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).

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).

The heat preservation function in dehydrators is designed to maintain a stable temperature after the drying process is completed. This function allows for keeping the temperature inside the device at a certain level, preventing the overcooling of products, which is especially important for long-term storage. The key point is preventing re-moisturizing, which helps avoid moisture that could lead to the growth of bacteria and mold.
