When evaluating and reviewing food dehydrators, the below product features and functionality should be considered and compared across different units and brands. One way to compare different brands of food dehydrators, that contain similar features, is to evaluate the food dehydrators on a price per square foot of drying area (total price divided by total drying area) while also considering the brand, reputation and product reviews of the dehydrator units that are being considered.
When you decide to compare the brands of different food dehydrators, you need to compare it using the same price per square foot of the whole total drying area before you can decide in choosing the additional extra costs that you want to add up.
Dehydrators remove moisture from food via heat and air flows. The air flow of food dehydrators from dehydratedfoodz.com happen to be designed either horizontally or vertically. Horizontal air flow food dehydrators have their heating element and fan located on one side of the dehydrator. It has also been known that in the horizontal air flow dehydrators, there are drying trays that are arranged like drawers inside the food dehydrator in order for it to hold foods. Simply saying, compared to the vertical air flow dehydrators, the horizontal ones are much more better in dehydrating different types of food and it is also beneficial since it mixes the food flavors less than compared to the vertical air flow dehydrators.
If you also want to keep everything clean and make the cleaning much more convenient for you, then you should resort to a horizontal air flow dehydrators here since it helps stop the food juices from dripping down so that it won't cause any dirt and mess. If you happen to find the heating element and the fan of the dehydrator on its base, then basically, it is a vertical air flow dehydrator. If you find the drying trays at the top of the base, then it is considered as vertical air flow dehydrator. Because the drying trays and food are stacked on top of the heating element, drying temperatures can vary between the top and bottom food drying trays.
Vertical air flow dehydrators may require a swapping of top and bottom drying trays, during the dehydrating process, so that an even drying effect is achieved across all the food and drying trays.
The thermostat of food dehydrators are also required so that it won't have an increase in temperature inside knowing that it without the thermostat, it can cause dehydration inside. Everyone should avoid dehydration and constant unchanging heat inside since it can cause food hardening which may result to bacteria inside the food.
