Depending on factors such as knife type and sheet thickness, the steam pressure may be reduced to prevent over‑steaming; the specific procedure shall follow the process documentation approved by the R&D department. 2. Steaming/cooking time ≥ 2 minutes
5	Fried	Fryer	Frying temperature settings: initial oil temperature: 120–130°C; subsequent oil temperature: 148–165°C. Frying time: 80–120 seconds, until the dough rounds achieve a golden‑yellow color.
