II. Production Process and Standard Operating Procedures (SOP)
The following is a guide to core operations and parameter settings based on real-machine commissioning and debugging:
1. Bottom Flour Dusting System Preparation
- First, add dry flour into the lower dry flour hopper.
- Pull out the baffle pin to let the flour fall onto the conveyor belt that feeds the dough sheet.
- Loosen the screws on both sides. Pushing the inserting plate inward will dust two thin layers of flour; pulling it outward will dust a single layer to prevent the dough sheet from sticking.
2. Filling Pretreatment and Evacuation Test
- Filling Requirements: Ingredients/particles must be finely chopped or ground, and the filling should have some binding/viscosity (not too crumbly). Place the filling into the filling port and hopper.
- Filling Test: The switch on the right side of the control panel regulates filling. Turn on the switch to adjust the speed, monitoring air discharge and filling output. Tip: Keep the speed slow initially; you can hold the hose to feel the flow. Once the filling is discharged smoothly from the forming end, turn off the filling switch.
3. Dough Sheet Conveying and Precise Thickness Adjustment
- Dough Pretreatment: First, press the dough into a sheet approximately 1 cm thick, with a width similar to the conveyor belt.
- Start Dough Sheet Conveying: Turn on the dough conveying switch on the left. Set a slower speed initially, then adjust it to a value of around 10.
- Lay the dough sheet flat on the pressing rollers, and sprinkle some dry flour on the surface to prevent sticking.
- Thickness Adjustment (Critical): Adjust the thickness of the dumpling wrapper using the gear knobs on both sides. Turn upward to thicken and downward to thin. The recommended ideal wrapper thickness is approximately 1.6mm.
4. Dough Sheet Feeding and Waste Material Recovery
- After the dough sheet exits the pressing rollers, support and guide it by hand into the forming roller molds below. Make sure the dough sheet does not pile up here.
- Pull up the excess waste dough sheet (trimming scrap) after cutting and hang it on the white recovery roller.
5. Synchronized Forming and Parameter Matching
- Turn on the filling switch again. As the filling flows out and is packed into the wrapper, slowly adjust the filling speed.
- Parameter Reference: During the initial testing phase of the machine, it is recommended to set the left speed (dough sheet conveying) to around 10 and the right speed (filling) to around 8.
- Fine-Tuning Tips:
- If too much dough sheet piles up in the middle, tighten the knobs on both sides.
- If the dumpling wrapper breaks or bursts at the forming mold, the dough is too firm; you need to knead the dough to be slightly softer.
- Emergency Stop Protection: The red button in the middle of the control panel is the emergency stop switch. Once pressed, all systems will stop working immediately; rotate it clockwise to release the emergency stop and resume operation.
