Rated 5 out of 5 by from Love my 2nd Excalibur dehydrator I purchased this model to replace an aging 9 tray dehydrator that was close to 20 years old. I can tell you without a doubt that I know I dehydrated a ton of meat for jerky with out any problems. I used the old model so much that the bottom of the unit where it sat on the 4 legs completely vibrated through. Finally the whole bottom side cracked but not from any factory problem. I have used the new one 3 times so far and the jerky that came off of it was perfect. Thank you Excalibur for making a fabulous product. Do not hesitate to purchase an Excalibur you will not be disappointed. Craig

Rated 5 out of 5 by from Bigger Fan!! I already owned a 5 tray system and liked it very much. During fig harvest it was drying almost round the clock. I bought the 9 tray because my harvests were up to 600 pounds a week and I needed to be able to dry a larger quantity. (I am a commercial grower.) I love the bigger fan and how much more even and faster the figs dry in this larger machine. The clear window on the door makes it easy to check the progress without opening and letting the heat escape. I don't have to rotate the trays and I am finding that I am knocking about 3 hours off my old drying time. The control panel is easy to set and I like the count-down clock and auto stop. No more over dried figs. I dried some fresh tomato chips along with mango and pineapple in the new machine and it was delicious! I am most pleased and impressed with Excaliber products. I chose Excaliber over other companies because of the 10 year warranty vs. the others that might offer a year or two. They believe in their product and the quality is very apparent.

Rated 5 out of 5 by from I purchased this product to dehydrate some backpacking meals and discovered so much more. I'm new to dehydrating and love it. Rarely a day goes by that I'm not experimenting with something. Nothing will ever go to waste in our home ever again. I love the temperature and timer features.. so happy I bought this top of the line product.

Rated 4 out of 5 by from working well I like the many shelves and even drying, the time and temperature features are great. My reserve: I feel it was too expensive for the quality. The fragile plastic canvas holders and use of plasic canvas with no edge to prevent the cut edges from catching on anything. plus, no slight ridge to prevent food from rolling right off was hard to accept for an over $350 item. Because it does the job, and the good warrenty, I am keeping it. Thank you for asking my opinion.

Rated 5 out of 5 by from Meets all my demands I wanted a quiet dehydrator that would be a regularly used appliance in my kitchen. It needed to fit a large quantity to make dehydrated food a part of our regular diet. My perfect dehydrator needed to have specific temperature and time controls as well. This dehydrator meets every requirement and then some. I love that you can take the door off to check on the food without stopping it or re-setting the timer. The nine trays fit a huge amount of food! I can fit four thinly sliced tomatoes on each tray to make tomato chips. Then fill eight more trays! It is very quiet -- almost the exact same volume and pitch as my microwave. It's not a distraction nor a nuisance, and the entire family is now used to it running in the background as part of our normal routine. It sits right in the middle of the kitchen and is running daily with a new batch of healthy snacks. I have used other dehydrators in the past, but they never really dried the food well. This dehydrator is perfect for making chips out of vegetables that have real crunch to them. There is no case hardening and the products come out uniformly dried without rotating the trays. Well done Excalibur!

Rated 5 out of 5 by from My 2nd Excalibur I just got this one today and have already used it to dry peppers. It works great and I do really like the digital control and the clear door. I've been using Excalibur's for about 6 years now and my first one, which is a 3629TB, has never missed a beat. I bought a clear door for it recently, so now I feel like I have 2 new dehydrators.

Rated 5 out of 5 by from In constant use Since receiving my Excalibur I have had something going almost non stop. Here are my bullet points so far: -- This dehydrator holds a phenomenal amount a product. I was amazed the first time I used it! -- The drying is very consistent. I have heard that you need to rotate items when drying. While it might not hurt to rotate, if you forget don't worry. -- The book that came with the unit is very clear and takes some of the worry out of the process if you have never done this before (which I hadn't) -- I love the clear door. Some things to consider (by buyers and/or manufacturer): -- Cost. It is the highest priced unit on the market and I was actually surprised that the unit is almost entirely plastic (and super light for the size). Just seems kind of cheap (when it is not). -- The top shelf has significantly less space that every other shelf, so if you are rotating you can't put stuff on the top shelf. Increasing the overall height by 1/2 inch would solve this. -- If you are buying I would suggest that you get the tray liners. On our first products we placed items directly on the screens and they were a pain to clean. We are now using parchment paper and it is a pain to keep cutting to fit.

Does this unit have the guide on it that shows the temps for the different foods to dehydrate? Your other units have it next to the controls.

how often does it need to be cleaned and how, dishwasher, hand wash? Does it have to be used with the drying sheets?

Asked by: tenshot51elk
You want to wipe down the inside after each use. Trays and mesh screens are dishwasher safe but they may not fit in your dishwasher. So best to soak the trays and screens in the sink after each use.

what catches the drippings on the bottom from making jerky?

Asked by: anthonyap
The bottom of the dehydrator. Because our trays are removable, it's easy to wipe clean.
