Dough Sheeter Maintenance Guide: Daily, Weekly, and Long-Term Care
The dough sheeter (压面机) is the core equipment in flour-based food processing. Regular maintenance ensures operational efficiency and food safety. Through systematic maintenance, you can extend equipment lifespan, reduce downtime due to malfunctions, and ensure the safety and quality of flour-based food production.
Pre-Operation Safety Checks
- Power cord inspection: Check the power cord for integrity before operation to ensure there is no damage or wear.
- Voltage stability: Ensure a stable voltage supply before starting the machine.
- Environment: Avoid operating in damp or humid environments to prevent electrical hazards.
Safety Precautions During Operation
- Hand and tool safety: Strictly prohibit inserting hands or tools into the feed inlet during operation.
- Jam handling: If a jam occurs, immediately cut off the power and wait until all components have stopped rotating before clearing the blockage.
- Continuous operation limit: Do not run the machine continuously for more than 30 minutes to prevent motor overheating.
- Motor overheating: If the motor overheats, stop the machine immediately and allow it to cool down before resuming.
Daily Maintenance
- Rollers and cutting blades: Clean daily using a soft cloth for wiping. Avoid sharp tools that could scratch the surfaces.
- Gaps and crevices: Use a fine-bristle brush to remove residual debris from gaps, ensuring hygiene standards are met.
Weekly Maintenance
- Drive belt inspection: Check the tension and wear condition of the drive belt weekly. Adjust or replace as needed to maintain optimal performance.
Bi-Monthly Maintenance (Every Half Month)
- Bearings: Inject food-grade lubricating oil into bearing components every half month to prevent friction damage and ensure smooth operation.
Long-Term Maintenance
- Fasteners: Inspect all fasteners monthly to ensure none are loose, preventing vibration-related issues.
- Long-term storage preparation: Before extended periods of disuse, clean all components thoroughly and apply food-grade anti-rust oil to protect metal surfaces.
Operator Training Requirements
- Safety training: Operators must receive proper safety training before operating the machine.
- Emergency stop: Familiarity with the location of the emergency stop button is mandatory for all operators.
- Basic troubleshooting: Operators should be trained in basic fault handling procedures to respond quickly to common issues.
Quick Reference Maintenance Schedule
