Selecting chain oil in food production lines is critical for both ensuring long-term equipment operation and maintaining food hygiene. Incorrect oil selection can lead to both chain wear and food contamination.
1. Selection Criteria
A. Food Grade Certification
- Chain oils that are NSF H1 or FDA compliant should be used.
- Ensures hygiene and safety in lines with a risk of food contact.
B. Operating Temperature
- In high-temperature areas such as oven, cooking, and drying lines, high-temperature chain oils should be preferred.
- The maximum temperature tolerance must be suitable for chain and line conditions.
C. Viscosity and Adhesiveness
- Must have sufficient fluidity to ensure adequate contact between chain links and pins.
- Too fluid oil → runs off, too viscous → hinders movement.
D. Wear and Pressure Resistance
- If the chain operates under heavy loads, EP additive chain oils should be preferred.
- Extends chain life by reducing wear and friction.
E. Water and Chemical Resistance
- For chains near washing or CIP lines, choose chain oils resistant to water and cleaning chemicals.
2. Areas of Use
| Production Area | Chain Oil Recommendation | Maximum Temperature |
|---|---|---|
| Oven and Cooking Line | High-Temperature Food Grade Chain Oil | 180–220°C |
| Conveyor Lines | NSF H1 Food Grade Chain Oil | 100–150°C |
| Filling and Packaging Line | Low-Viscosity Food Grade Oil | 80–120°C |
| Drying and Oven Production | High-Temperature Grease | 200–250°C |
3. Application Recommendations
- Correct amount of lubrication: Too little → wear, too much → residue and buildup.
- Regular maintenance: Lubrication intervals should be determined by production speed and temperature.
- Cleaning: Lubrication should not be applied until the chain is free of dirt and residue.
