A drum motor is a one component conveyor drive where the motor, gear drive and all moving parts are enclosed inside the drum. The motor and gears operate in a sealed oil bath ensuring proper lubrication and cooling. With no external motor, gear reducer, sprockets, chain or OSHA required chain guard, no external component maintenance is required. Because of these features, sanitary drum motors are an ideal drive motor option for conveyor systems in the processing zone and raw-food handling areas of food plants.
Food allergens can be a major safety concern for food manufacturers and packagers. As a food manufacturer, you know you are responsible for the safety of your products. With an estimated 16 million Americans with food allergies, including 5.6 million children under the age of 18, allergen contamination is of high concern.
Manufacturers are under increasing pressure to make sure they keep allergen contamination out of their production facilities. Cross-contamination can occur from inadequate cleaning of a production line so that residue from an allergen remains on the line and is picked up by the next product being made there.
Conveyor belt sag, also known as catenary sag, refers to the tensionless section of the belt that hangs down on the return side (or underside) of the conveyor. It is an intended section of the belt that is required to keep your conveyor running smoothly.
The catenary sag is a natural way to tension the belt. It allows gravity to give the belt the exact amount of tension instead of relying on a mechanical take-up or tension system. Mechanical take-up or tension systems are required when catenary conveyor belt sag is not included in the design of the conveyor system.
Conveyor systems, even maintenance-free conveyors, are machines with many moving parts. Inspection and cleaning will be required if you want to keep your maintenance-free conveyor system exempt of maintenance and get the most out of your conveyor investment.
Inspection and cleaning will help prevent minor problems from mushrooming into large maintenance problems that can result in major work stoppages for your conveyor system. Your conveyor maintenance personnel should develop a routine for inspecting and cleaning your conveyor systems. Careful records detailing periodic inspection and cleaning should be kept and recorded.
