A frozen food production plant of a French multinational operates 13 production lines and produces 12,5 tons of frozen food per year. To handle heavy freezer doors, a chain system is used to open and close them. With extreme operating temperatures of up to -30°C, adapted lubrication frequencies are needed.

A FREEZER HANDLING CHAIN IN A FROZEN FOOD PLANT.
CASE
CONTEXT
PROBLEM
High hygiene regulations are in place, therefore the production floor is cleaned regularly. After cleaning the chains are under lubricated. The tensioner sprocket pitch needs to be adapted regularly to the chain. As a consequence the chain needs to be changed every two years.
SOLUTION
Next to changing the lubricant towards a more suitable product for the extreme negative temperatures on the floor, a MEMOLUB® PLCD was installed for every chain. The installation of this PLC programable automatic lubricator allowed the customer to fully customise the lubrication schedule based on their needs. In this case a 2 minute ON and 22 minutes OFF scheme was implemented during 1 hour after cleaning the facility floor.
RESULTS
- No more adjustments made to the chain tensioner.
- After 1 year, the same system was implemented at all production sites of the company,
