Where is the Excalibur made?
Made in the USA. Sacramento, California.
What can I dehydrate?
In an Excalibur, just about anything. Fruits, most vegetables, meat, fish, make your own fruit roll-ups. Make vegetable powders. Dry herbs and spices. Make your own soup mix, trail mix, and salad dressings. Dehydrate grains and dairy products. Make all types of crackers. Use for arts & crafts, such as drying flowers for potpourri, or dough art, or drying photos. Make home-made pet treats for your dog, cat, horse, birds, etc. Dentists dry plastic molds in our Excalibur!
Are home dried foods cheaper & better than those in health food stores?
For the most part, YES! It costs 1-tenth to dry your own instead of buying at a store. For most people eating dehydrated foods, the dehydrator pays for itself within 4 months vs. buying dehydrated foods at a store. Read the list of ingredients in commercially prepared “dried” foods. You may find added chemicals used for preservation, as well as saturated fats indicating the food may have been fried rather than having the moisture removed.
Explain the Dehydration Process?
The most critical aspects of the process are (1) the difference between air temperature and food temperature and how the evaporation process keeps food temperature cooler than air temperature (2) the working of the thermostat and how it causes the air temperature to fluctuate up and down (3) understanding at that the enzymes are most susceptible to destruction by heat in the wet state. After food is dehydrated the enzymes can withstand much higher temperatures.
Food Temperature vs. Air Temperature?
In general, food temperature is about 20 degrees cooler than air temperature. This is due to evaporation. As the moisture on the surface of the food evaporates, it cools the food. We have discovered this through hours of testing and measuring the air temperature and food temperature simultaneously during the dehydration process using a Doric Tendricator with type j thermal couples. The temperature reading on the Excalibur dial refers to the food temperature. If you set the Excalibur at 105F, you are setting it to hold the food temperature at 105 but the air temperature may get as high as 124F.
Why is the Temperature on the dial different than my food temperature?
The Excalibur thermostat was never originally designed to hold an accurate air temperature. It was designed to control an accurate food temperature.
How does Excalibur’s Thermostat Work?
Through our research, we have found that in order to preserve the enzymes and reduce risk of mold and bacteria, there must be a fluctuation in temperature. Enzymes and microorganisms thrive at the same temperature, so during dehydration we have to accomplish two things: (1) keep the food temperature low enough not to harm the enzymes (2) elevate the air temperature high enough to remove moisture quickly to stop the growth of mold or bacteria. The air temp rapidly rises to the high point, so moisture is quickly evaporated off the food’s surface. As the temperature lowers, the dryer surface pulls moisture from the center of the food and becomes saturated again. Because of the up and down fluctuation of air temp and constant evaporation, the food temp remains at a lower temperature. After all the food moisture is evaporated, the food temperature will rise and equalize somewhere in the middle of the air temperature fluctuation. This will not kill the enzymes. Remember, the enzymes are only susceptible to damage in the wet state. Once food is dehydrated, the enzymes become dormant and can withstand much higher temperatures. We spoke with Viktoras Kulvinskas about this and he confirmed we are right “dry enzymes can survive well up to to 150F.” Viktoras tested our Excalibur and found it high in enzymatic activity. We have done our own tests with various seeds, dehydrating them at different temperatures, soaking them again, to see if they sprout and they did. Proving the enzymes are alive.
Enzyme Destruction Temperatures?
Excalibur’s founder, Roger Orton, worked with Ann Wigmore on our Excalibur Dehydrators. Ann said that food temperature had to go above 120F for a period of time before enzymes were destroyed. Viktoras confirmed the same. Ann tested many dehydrators and confirmed Excalibur to be the best for Living Foods. She found the best technique to save enzymes was to set the temperature higher initially, then turn it down after a few hours. However, most people will not know when to turn it down. Ann’s recommendation is to set the temperature at 105F for the entire cycle. That way, the food temp will never go above 120F even after its dry.
Is the low temperature good for Living Foods and the high temperature safe for Meat?
“Living foods” are healthy foods containing living enzymes. Excalibur’s Adjustable Thermostat lets you dry foods at temperatures low enough to keep enzymes viable in fruits and vegetables. It also lets you set temperatures high enough to dry meat for jerky. The temperature on the Excalibur is the average temperature. The air will fluctuate above and below that. In the case of meat, if the temperature is set at 155F, the air temperature will hit the USDA safety recommendation of 160F.
Is it safe to dehydrate Meat in an Excalibur?
YES! The temperature setting on the Excalibur is the average temperature. The air will fluctuate above and below that. In the case of meat, if the temperature is set at 155F, the air temperature will hit the USDA safety recommendation of 160F. Most dehydrators do not reach the minimum safe temperature for meat.
Why should I use an Excalibur vs. my oven to dehydrate?
Most ovens don’t have a low enough temperature setting for Living Foods. Ovens don’t heat evenly, you’ll have to constantly flip and rotate your load of jerky. Heating an electric or gas oven is expensive and you waste energy overheating the kitchen. Excalibur runs at an average 4 cents per hour and won’t heat up the kitchen. An oven has 1 or 2 shelves; Excalibur has up to 9 trays. Excalibur is easy-to-clean with a damp sponge.
Is the Excalibur Tray Screen Material BPA free?
Yes. We use polypropylene #5. It’s the safest plastic for food contact. For the case material, we use polycarbonate because it’s virtually indestructible. Food does not come into contact with the case material. Food will only come into contact with the polypropylene #5.
Is the case material FDA approved polycarbonate?
Yes. The case material is safe and doesn’t give off harmful fumes when used under 160F. Other manufacturers use a lower-quality plastic that does give off harmful fumes. The polycarbonate we use is recognized as safe by the U.S. Food & Drug Administration, European Commission’s Scientific Committee on Food, United Kingdom Food Standards Agency, Japanese Ministry of Health, Labor and Welfare, and other regulatory agencies Worldwide. *Always be sure you have FDA approved food contact polycarbonate. There are many different types of polycarbonates.
Are the trays dishwasher safe?
Yes. In the top tray of your dishwasher. Or clean with a damp cloth and mild detergent. The tray inserts are also easy to clean by soaking in the sink, then rinsing with a quick spray from the sink sprayer.
Will the timer turn off the dehydrator while I’m away or asleep?
Yes. Just set it, and forget it. We use a premium quality, motor driven timer. If the power should go off and on, the timer keeps track of the actual drying time.
Can the Excalibur stay on unattended?
Yes. The Excalibur has three separate circuits to protect them from electrical malfunctions.
