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).
A mesh for herbs and spices is included in the delivery set of the food dehydrator.
These meshes are characterized by a finely porous structure to prevent herbs and spices from falling through the mesh holes. They are made of silicone or stainless steel, and more rarely of bamboo. There are also variants with non-stick coating, which prevents food from sticking to the surface of the mesh.
The material from which the complete trays of the dryer are made.
—
Plastic. Inexpensive, but at the same time very practical material. In terms of strength and overall reliability, the plastic is inferior to metal, however, during normal use of the dryer, this difference is not noticeable. In addition, if such trays are made in the form of complete compartments, their walls can be made transparent so that you can observe the contents without interrupting the process and without knocking down the temperature regime. However the transparent walls gradually become cloudy due to the low resistance of plastic to scratches — however, it takes a lot of time for this moment to become a serious inconvenience. Thus, most modern dryers use plastic trays.
—
Stainless steel. The main advantages of metal trays are strength and resistance to overheating. On the other hand, these advantages rarely turn out to be significant, and steel is more expensive than plastic. In addition, if metal trays are made in the form of separate compartments, they are opaque, and to check the condition of the products, you will have to open these compartments, lowering the temperature and disrupting the process. . For models with a rear fan (see above), this point is not relevant — they usually have a transparent door; however, such devices are not cheap. Thus, this tray material is rare nowadays — mainly among advanced dryers.
