Bakery oven lubrication
Thermal lubrication of oven chain and roller
Also known as: Bakery-oven chain lubricant · Bakery-oven roller lubrication · Bakery-oven rail lubricant · Low-fume lubrication for food ovens
Graphite film for bakery-oven chains and rollers.
[ Technical summary ]
In a bakery oven, heat degrades grease and produces fumes and residue. A graphite film lubricates chains, rollers, and rails without depending on an oil that evaporates. This record covers bakery ovens; tortilla machines and industrial heat-treatment furnaces are separate uses. The sanitary requirement is set by the plant; no food-contact certification is claimed here.
Each process needs a specific product and application method. ESGRAF selects the solution according to temperature, material, load, cycle, and application method.
[ Problem it solves ]
Lubricate bakery-oven chains and rollers without fumes or grease that degrades with heat.
Processes
- Continuous bakery baking
- Oven chain and roller lubrication
Operating conditions
- Continuous heat on an oven line
- Environment where grease fumes are not acceptable
When it is suitable
- Grease fumes or degrades in the oven
- Chains, rollers, or rails squeal with heat
- The plant requires lubrication without volatile residue
When it may not be suitable
- The oven manufacturer specifies a particular lubricant
- There is direct food contact and the plant does not allow black residue
- The surface tolerates no black residue and there will be no cleaning stage
Process challenges
- Heat degradation of grease
- Fumes and odor in the plant
- Line sanitary requirement
Advantages
- Lubrication that does not depend on an oil that evaporates
- Less fume than oven greases
- Adherent film on chain and roller
Limitations
- Does not claim a food-contact certification
- May leave black residue if over-applied
- The interval is set by the oven cycle
