Taisho Denki electronic fermentation machine with 4 shelves, temperature adjustable from 20-40 degrees Celsius. - Brand: Taisho - Function: Electronic fermentation machine - Number of shelves: 4 - Temperature adjustment: 20-40 degrees Celsius Purchased over 10 years ago, it still functions perfectly. It makes a huge difference compared to the fermentation function of a microwave oven, allowing for a more gentle rise. Also, when using the oven's fermentation function, the dough can dry out while waiting for the oven temperature to increase after the second rise, but using a dedicated fermentation machine prevents this. Furthermore, you can bake rolls and other quick-baking breads one after another if you keep them in the fermentation machine. The pink cover is handmade from fleece for use when the room temperature is low. I will wrap the fermentation machine in it as cushioning material for shipping. It can be folded and stored when not in use. Thank you for looking.
