When a machine is running, it is inevitable that the chain cover will be shaken. The grease drop inside a cover
will be shaken as well until it is dropped down to fish sheet. This condition can lead to After our investigation, we found that the tray support of fish sheet cooling conveyor could not
prevent a drop of grease because drainage holes from tray move out of the bottom tray supports. (See photo)
When a machine is running, it is inevitable that the tray be shaken. The grease drop on tray
will be shaken as well until it is dropped down to fish sheet. This condition can lead to contamination
problem because the fish sheet on running conveyor belt is still unwrapped-no film wrapping
Next, normally, we do a cleaning our production area and machine twice a day; before and after work.
There is no cleaning up during working hours. Therefore, when such contamination of grease drop occurred
during the day, it is very difficult to catch out.
