4. Frequently Asked Questions (FAQ)
- Q: Can this machine handle low-hydration/stiff doughs (such as ramen dough or bagel dough)?
- A: Yes. The N Series is specifically designed for heavy doughs. The robust spiral hook and double-action system easily handle low-hydration doughs. However, for exceptionally stiff doughs, we recommend limiting the batch size to approximately 70% of maximum rated capacity to reduce machine load and prolong service life.
- Q: Can I switch between high and low speeds directly while the machine is running?
- A: Yes, but to provide optimal protection for the two-speed motor and mechanical gear transmission, it is strongly recommended to slow down or briefly press Stop before switching from slow speed (101 r/min) to fast speed (200 r/min), adjust the gear, and restart.
- Q: What are the benefits of a double-action system (bowl and hook rotating simultaneously)?
- A: The double-action system ensures that every part of the dough is evenly kneaded. It prevents the dough from merely wrapping around the center column, significantly reduces friction heat (preserving yeast activity), and cuts kneading time in half compared to fixed-bowl dough mixers.
