The Best In Oven Thermostat

Excalibur 3900B 9 Tray Excalibur Black

The 3900B Deluxe Dehydrator by Excalibur comes with 9 trays and a total of 15 square feet of drying space. The adjustable thermostat temperature control ranges from 105 to 165 degrees Fahrenheit, 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 dehydrate faster, retain more nutrients, and look and taste better – all without manual 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 safer, better, and faster, thanks to Excalibur’s patented Hyperwave Fluctuation technology. 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.

Product Features

• 9 trays and 15 square feet of drying space.
• No moving food or trays during dehydration.
• Adjustable Thermostat 105 to 165 degrees Fahrenheit. Safe to dry meat for jerky.
• Accurate temperature controls to dry fruits, vegetables, meats, flowers, herbs, pet treats, arts & crafts.

• Remove trays as needed to increase the height needed to dehydrate bulky items or raise dough.
• 7-inch fan, 600 watts. Unit Dimensions: 12-1/2 H x 17 W x 19 D (inches)

Square trays hold more food to dehydrate faster. Removing trays gives you more space for dehydrating larger food items or raising dough.

The Excalibur food dehydrator can do it all. 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.

Excalibur Hyperware Fluctuation Technology prevents the food from hardening or growing mold by raising and lowering the temperature.

Why the Breville Smart Oven?

Every Breville product begins with a simple moment of brilliance. The Breville Smart Oven began with the simple fact that different foods require different methods of heating: some, like baked goods, need to be cooked evenly; others, like meats, need to be seared on top. Most toaster ovens fail to distribute heat in a consistent way throughout their interiors, let alone change heat distribution to suit the different foods being prepared. This is how the Breville Smart Oven stands apart: whatever the food, it adjusts its heat distribution for perfect results.

For toast, high heat from top and bottom evenly crisps the outside of toast but doesn’t dry out the inside (left diagram), while for baking 1500W are distributed among four elements for gentle heat and even cooking (right diagram)

An oven that does the thinking for you

The Smart Oven is equipped with Element IQ cooking technology, which adjusts the power of the five individual quartz heating elements to cook food more evenly and quickly. This sophisticated heating system distributes heat throughout the oven when and where it is needed, to guarantee more efficient cooking. Nine different menu options allow users to choose the best setting for the food they are cooking. In addition to dynamically distributing heat to different areas, the Smart Oven can adjust the wattage of its heating elements for even more cooking flexibility. Most ovens have elements with fixed wattage that can only switch between ON and OFF, but Element IQ functions much like a dimmer on a light switch, increasing or decreasing element power with a simple turn of the knob.

The Breville Smart Oven comes with 3 acccessories: a pizza pan, baking pan, and broil rack.

For example, broiling requires high heat from above in order to melt and brown, so the Smart Oven activates 1500W of high heat from the top elements of the oven. On the other hand, toast needs to be cooked evenly on both sides without drying out the inside, so the Smart Oven uses high radiated heat from above and below (1800W distributed between four elements) to crisp the outside quickly.

Baking utilizes another feature of the Smart Oven that contributes to even heating: convection heating. Convection cooking uses a fan to circulate hot air so all sides of the food cook at the same rate. This is particularly important for baked goods, such as cookies and cakes, which need to be cooked evenly all the way through.

Each of these nine functions is preset with recommended settings, taking the guesswork out of cooking. However, each can be customized according to recipe, volume of food, or personal taste. Customized settings will remain in the memory of the oven until changed or until the oven is unplugged from the wall outlet, streamlining your cooking process.

Designed with the consumer in mind

The Smart Oven is carefully constructed from the most durable materials. It is attractively housed in reinforced stainless steel, a striking addition to any kitchen. The elements themselves are composed of quartz, rather than the metal elements found in other toaster ovens. Quartz responds more quickly to heat change, which results in more even heating throughout the oven. The roomy interior is coated with a non-stick material that can safely withstand high temperatures, making cleanup easier. A crumb/drip tray that is accessible from the front of the oven (rather than the back, like many other toaster ovens) also makes it easier to clean between cooking sessions. In addition, the oven includes a patented magnetic auto-eject rack: small magnets embedded on the sides of the oven door pull the wire rack halfway from the oven when the door is opened, making food easier to remove and preventing burns.

Goldilocks proportions

At 18.5 x16.25 x11.25 inches, the Breville Smart Oven is not too small but not too large. It is larger than most toaster ovens, with space to comfortably fit six slices of toast, a 13-inch pizza, or a whole chicken. However, as a countertop convection oven, it is more space-efficient than a conventional wall oven. A smaller oven means less time to heat up and less time to cook, perfect for preparing a meal in a hurry (or for cooks who like to create in the heat of the moment). This also translates into a cooler kitchen (particularly convenient in the hot summer months) and less energy consumed.
