Best Presto Dehydrators

The Excalibur 2900ECB comes with 9 trays, a total of 15 square feet of drying space. The adjustable thermostat temperature control ranges from 105◦F to 165◦F making it safe to dehydrate meat for jerky. The fan, heating element and thermostat are in the back of the unit, so cool air is drawn in, heated and then distributed evenly over each tray. This patented Parallex Horizontal Airflow is exclusive to Excalibur and helps the food to dehydrate faster, retain more nutrients and look and taste better, without tray rotation. Since 1973, Excalibur has been made in Sacramento, California. Over the years, Excalibur has taken the lead in advancements related to the mechanics of dehydration including air flow, heating dynamics, and materials. Any dehydrator will dry food. An Excalibur dries better, faster & safer thanks to Excalibur’s patented Hyperwave Fluctuation technology. Ordinary dehydrators produce constant, unchanging heat causing “case hardening.” Basically a dry surface with moisture trapped inside – the perfect environment for yeast, mold and bacteria growth. With the Excalibur Hyperwave Fluctuation technology the air temperature fluctuates up and the food’s surface moisture evaporates, then the air temperature fluctuates down and 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, overcoming yeast, mold, and spoilage. Dehydrate Fruits. Dehydrate Vegetables. Dehydrate Meat or Fish for Jerky. Re-crisp breads, crackers, etc. Make soup mixes and reconstitute later. Make animal / pet treats. Use for arts & crafts such as cake decorations, potpourri, dough art, drying photographs.
