Fruits, vegetables, jerky, herbs and pet treats all dry at different rates, which is why this dehydrator makes both variables adjustable rather than fixing them. Temperature runs from 30 to 75 degrees Celsius, roughly 86 to 167 degrees Fahrenheit, low enough for delicate herbs and high enough for dense meat. The timer covers 1 to 24 hours. Cooking guides in the instructions give a starting point for each food. Seven stainless steel trays stack inside, each measuring 12 by 11.2 inches, and steel rather than plastic means they hold their shape under a wet load and wash clean without absorbing odor from a previous batch. Even drying across seven levels comes from 360-degree airflow circulation, which moves heated air around the whole stack so the trays nearest the element do not finish while the far ones are still damp. Monitoring does not require opening the door and dumping the heat. A transparent door panel with bright LED lights behind it shows every tray, so progress is judged by eye. Settings are entered on a digital LED display with backlit buttons, readable even in a dim corner. A built-in thermostat holds the temperature that was set, and overheat protection guards the 600-watt element through a long overnight run. Strong metal hinges keep the door securely closed against the airflow, and anti-slip foot pads hold the unit steady on the counter. A mesh screen and drip tray are included with the trays, and every removable part cleans up quickly. The stainless steel, galvanized metal and PP body measures 13.39 by 15.94 by 12.6 inches and weighs 16.87 pounds.
