Lubrication change solves oven conveyor problems

Seven major bakeries had contacted a lubrication producer over major problems with oven conveyor chains. The solution may also be of interest to other industrial oven operators too.

Seven major bakeries had contacted a lubrication producer over major problems with oven conveyor chains.

The solution may also be of interest to other industrial oven operators too.

Over the past 18 months Kluber Lubrication have been contacted by no less than 7 major bakeries from London to Dublin.

All the bakeries were experiencing similar problems with their oven chains, irrespective of whether they were using Mecatherm, Barrimule or Gouet baking ovens.

Following site surveys at all the plants it soon became apparent that the problems encountered of chain seizures, excessive wear, chain failure and unreliable machine operation were down to one culprit - namely the lubricant in use.

Due to the high temperatures, in excess of 220degC, inflicted upon the chain during the baking process, the previously used lubricant had a tendency of burning off leaving a build up of solids in the chain clearances resulting in expensive chain seizure and machine failure.

Hotemp OY 95 which is the recommended lubricating oil from Messrs Mecatherm, France, for lubrication of Baking Oven transport chain subject to high temperature influences was put forward as an alternative to all the bakeries experiencing these problems.

Hotemp OY 95 can be applied to the baking oven chains via a centralised total loss lubrication system, or via automatic drip feed brush applicators.

Even with oven process temperatures in the region of 250degC during manufacture the ovens have now run in excess of 12 months with no reported chain wear or lubricant carbonisation problems.

"Since switching to your product the oven has run for 14 months problem free.

We feel confident using your product and have been more than satisfied with the service and support provided by Kluber Lubrication".
