Set the required temperature and duration and let the machine manage the rest, reducing the need for constant monitoring. Generous capacity for family needs: 5 liters of working capacity with an inner pot diameter of 29.5 cm and a height of 12 cm. Suitable for large batches of dough or multiple doughs, and for keeping dough warm as needed.

Versatile performance for dough work: Ideal for sourdough fermentation, dough proofing, and keeping dough warm between steps. Built for repeated use and dependable operation. Use scenarios: Overnight sourdough fermentation: set a comfortable temperature (for example 3040 C) and let the dough rise for 812 hours. Largebatch dough proofing: ferment or proof enough dough for several loaves in one session, reducing batch handling. Mealtime prep and warming: keep dough ready and warm for easy baking during family meals or gatherings.
