2. Production Process and Standard Operating Procedures (SOP)
Core operating guidelines and parameter settings compiled based on real machine commissioning and operational experience:
1. Filling Pre-treatment and Exhaust Test
- Filling Requirements: Filling ingredients/particles must be finely chopped or ground uniformly; the filling should possess a certain cohesiveness (must not be too loose). Place the prepared filling into the feeding hopper.
- Feeding Test: Turn on the feeding control switch, adjust the feeding speed from slow to fast, and observe pipeline exhaust and filling output. Tip: Keep speed low in the initial stage and feel the flow velocity by touching the feeding pipe. Once filling output at the forming end becomes smooth and even, proceed to the pressing stage.
2. Wrapper Placement and Forming Operation
- Wrapper Preparation: Select pre-made dumpling/gyoza wrappers with uniform thickness.
- Wrapper Placement & Forming: Place the wrapper flat in the center of the forming mold tray, then trigger the filling & pressing switch (or step on the foot pedal switch).
- Thickness and Filling Amount Adjustment (Key): Precisely control the filling weight per injection via the filling adjustment knob to perfectly match the wrapper size, ensuring wrapped dumplings are full and plump without breaking the skin.
3. Synchronous Forming and Parameter Matching
- Enable continuous or single-operation mode, and gradually fine-tune the forming rhythm and filling speed as filling is precisely injected into the wrapper.
- Fine-Tuning Tips:
- If the dumpling seal is not tight, adjust the mold pressing stroke or clean debris from the mold edges.
- If dumpling wrappers burst, it indicates excessive filling or dry/hard wrappers; reduce filling quantity appropriately or adjust wrapper formula.
- Emergency Stop Protection: A prominent red emergency stop button is located at the center of the control panel. In case of emergency, pressing the button immediately stops all systems; turn clockwise to reset and unlock.
