Folding Design

Big enough to fit a large mixing bowl, several hand-shaped loaves, 2 gallons of yogurt, or your favorite 8 quart pot, yet easily folds flat (with rack and water tray stowed inside) for convenient and compact storage in a kitchen drawer. Add an accessory shelf for even more room.

Wonderful Bread!

"Love this product. When unfolded, I have plenty of room for my big bread bowl. When folded, it takes up very little space. The controlled temperature and humidity mean I get consistent results."  Garvin S., 04/11/2021

“The Brod & Taylor SAHARA Folding Dehydrator and the Folding Proofer and Slow Cooker are essential to what I do. I’ve used these tools nearly every day since I got them. If you’re at all interested in doing bread, fermentation, dehydrating, or just about anything interesting in your cooking, then you need to have these in your kitchen.”

Amazing Product - Proofer - Highly Recommend

We purchased the proofer for our waffle business. We use dough for our waffles and needed a proofer to get them to rise a bit faster. We received the best customer service, which was very helpful and they answered all of our questions before we purchased this product. We received the product very quickly, in just a few days and have used this product everyday for the past week. It heats up very quickly and allows our dough to rise much quicker. We put our stainless steel bowls in the proofer and in less than an hour we are ready to use our dough. The size is perfect since we are in a little space and it folders flat when not in use. I highly recommend this product.

Folding Proofer from Brod and Taylor

The proofer has helped me tremendously. A friend showed me hers and how it worked and I had to have one. It has made my sourdoughs work so much better. I had given up on sourdough until I had this. Now sourdough is once or two times a week. Sourdough pizza tonight. Highly recommend this proofer.
