The use of high-temperature grease in the food industry is critically important, especially in machinery operating at high temperatures such as ovens, baking lines, sterilization equipment, and hot-filling lines. Incorrect selection can risk both the equipment and food safety.
1. Definition and Characteristics
- High-temperature greases are greases that are resistant to high temperatures and are food grade, meaning they are safe for surfaces that come into contact with food.
- They are typically approved by NSF H1 or FDA 21 CFR 178.3570.
- Temperature resistance: between 120–250°C (varies by product).
- Especially used in bearings, chains, belts, oven trays, and filling equipment.
2. Areas of Use
- Oven and baking machines
- Pasteurization and sterilization lines
- Hot filling machines
- Steam sterilizers
- Industrial kitchen equipment
3. Advantages
-
Food safety
- Does not transfer to products because it is food-grade certified.
-
Equipment protection
- Reduces friction at high temperatures and protects bearings and seals.
-
Performance and durability
- Does not melt or run due to heat.
- Increases the efficiency of mechanical components.
4. Points to Consider
- Material compatibility: The risk of reaction with plastics, silicones, and seals should be checked.
- Dosage and application: Excessive or insufficient grease reduces equipment efficiency.
- Storage: Should be stored in a cool, dry place in a sealed container.
- Inspection and maintenance: Periodic inspection should be carried out after using high-temperature grease; if deterioration or separation occurs, it should be replaced.
5. Risks of Incorrect Use
- Insufficient temperature resistance → grease melts, machine damage occurs
- Non-food grade product → risk of food contamination
- Inappropriate viscosity → wear and leakage in bearings or seals
