The core anti corrosion principles for sausage making machine are: adopting 304 food grade stainless steel, thorough cleaning and drying after every use, avoiding chlorine containing or strong acid detergents, and applying food grade anti rust oil for storage during idle periods.
1. Key Anti Corrosion Measures
Material Control: Components in contact with meat and parts subject to cleaning must be made of 304 or higher grade food grade stainless steel or food grade engineering plastics. Ordinary plated iron parts shall not be used.
Immediate Cleaning and Drying: Disassemble removable components after each use. Wipe with soft cloth and pH 6 8 neutral detergent, then dry immediately or air dry completely. Do not allow residual water to remain.
Cleaning Prohibitions: Do not use steel wool, chlorine containing bleaching agents, strong acid rust removers, gasoline or other organic solvents. These will damage the passivation film and cause pitting corrosion.
Protection for Idle Equipment: For long term shutdown, coat internal surfaces with food grade mineral anti rust oil. Store the machine in a dry, well ventilated area, away from acids and alkalis.
Regular Maintenance: Inspect weld seams and sealing rings every week. Light rust spots can be gently polished with #400 or finer abrasive sandpaper, followed by cleaning and oil application. Severely corroded parts shall be replaced.
2. Operational Precautions
Wipe along the grain direction of stainless steel during cleaning. Cross direction scratches shall be avoided, as they can initiate corrosion.
Residues of salt or seasonings should be softened with warm water prior to cleaning, to prevent localized corrosion caused by concentrated chloride ions.
For motor driven models, pay special attention to draining moisture from motor joints and screw gaps. Use compressed air blowing if necessary.
For household use equipment: prioritize prompt cleaning and thorough drying after each operation. For commercial use equipment: establish an Equipment Maintenance Record, and implement daily cleaning, weekly inspection and monthly maintenance regimes.
