Excalibur 3500B 5-Tray Electric Food Dehydrator Adjustable Thermostat Black
Ordinary dehydrators produce constant, unchanging heat, which can cause 'case hardening.' Ordinary dehydrators create a dry surface with moisture trapped inside the perfect environment for yeast, mold and bacteria growth. With the Excalibur Hyperwave Fluctuation technology, the temperature fluctuates up and down to prevent this from happening. When the air temperature fluctuates up, the food's surface moisture evaporates; then, when the air temperature fluctuates down, the the inner moisture moves to the drier surface. This keeps the food temperature low enough to keep the enzymes active, but the air temperature gets high enough to dry food and overcome yeast, mold, and spoilage.
