Daily Maintenance & Cleaning Checklist for Commercial Automatic Dough Kneading & Sheeting Machine

🔹 Daily Cleaning (Required After Every Use)

1. Safety First: Power Off
    
   Before any cleaning, disconnect the power supply and unplug the machine. Allow the rollers to cool completely to room temperature to avoid burns or electric shock hazards.
2. Remove Dough Residue
   • Use a soft, dry brush or silicone scraper to clear dry dough debris from the rollers, conveyor belt, hopper, and discharge chute. Never use steel wool or sharp metal tools to scrape the roller surface, as scratches will cause dough to stick in future uses.
   • For stubborn dough buildup, wipe gently with a soft cloth dampened with lukewarm water (35-40°C). Do not directly rinse the motor, control box, bearings, or electrical components with water, as this may cause short circuits.
   • Removable trays and the conveyor belt can be taken out, cleaned with food-grade neutral detergent, rinsed thoroughly, and dried before reinstallation.
3. Wipe Key Components
    
   Wipe the roller surfaces and stainless steel body with a clean soft cloth. Remove any detergent residue with a water-dampened cloth, then dry all food-contact surfaces completely to prevent bacterial growth or rust from moisture.

🔹 Weekly Maintenance (Inspection & Lubrication)

1. Check Drive & Adjustment Components
   • Inspect the belt/chain tension. If the sheeting speed slows or slips, adjust the tension promptly or replace worn parts.
   • Clean and lubricate the dough thickness adjustment mechanism (worm gear, worm) with a small amount of food-grade lubricant to ensure smooth operation without jamming.
2. Maintain Rollers & Scrapers
   • Check if the dough scrapers are properly aligned with the rollers. Adjust or tighten loose/deformed scrapers to ensure no dough residue remains on the rollers.
   • Apply a thin layer of food-grade salad oil to the roller surfaces. This prevents rust during long-term storage and reduces dough adhesion in subsequent uses.
3. Descale the Machine Body
    
   For water stains and oil buildup on the stainless steel body, wipe with a neutral detergent or diluted citric acid solution (1:10 ratio with water). Do not use chlorine-based cleaners (e.g., bleach), as they will corrode the surface.

🔹 Monthly/Quarterly Deep Maintenance (Periodic Overhaul)

1. Lubricate Core Components
   • Apply food-grade grease or manufacturer-specified lubricant to gears, bearings, chains, and other drive components at the designated lubrication points (refer to the machine manual). This reduces wear and extends the equipment’s service life.
   • Important Note: Use only a small amount of food-grade salad oil on food-contact surfaces (rollers, conveyor belts), and use mechanical lubricant only on drive parts to avoid cross-contamination.
2. Full Disassembly & Inspection
   • Remove safety guards and drive covers to clean internal dough debris and oil buildup. Check gear wear; if the lubricant is cloudy or contains metal shavings, contact the manufacturer for troubleshooting.
   • Inspect the power cord, plug, and switches for aging or damage, and verify proper grounding. Replace damaged parts immediately to eliminate electrical hazards.
3. Long-Term Storage Care
    
   If the machine will be out of service for an extended period, clean all components thoroughly, dry completely, apply anti-rust oil to metal parts like rollers and bearings, cover with a dust-proof cover, and store in a dry, well-ventilated area to prevent rust from humidity.

⚠️ Safety & Common Pitfalls to Avoid

• Never directly rinse the motor, control box, switches, or other live electrical parts with water during cleaning, as this may cause short circuits or electric shock.
• Do not use steel wool or hard brushes to scratch the rollers or stainless steel body, as scratches can harbor bacteria and cause dough adhesion.
• Always use food-grade lubricants only; industrial lubricants are strictly prohibited to prevent dough contamination.
• If abnormal noise, jamming, or overload shutdown occurs during operation, power off immediately to troubleshoot. Do not force the machine to run with faults.
