Packaging machine or multihead weigher, how to feed them?

The multihead weighers are particularly used for the packaging of bulk products such as dried fruits, vegetables, cookies, candies, frozen products...
The multihead weighers are generally used in the food and pharmaceutical industries.

The operating principle is the simultaneous weighing of several hoppers and the association of 2, 4 or 6 weighing hoppers which ensure the target weight with a high precision and a high rate.

Due to their height, the feeding point of multihead weighers is often high. The products are then packed on a bag, sack, drum or bucket packing machine. The feeding height of the weigher is therefore usually more than 3 or 4 meters.

• Loading with vibratory feeders 

Some applications allow direct feeding by the operator via a loading table.
The operator empties the bins, trays or bags on this loading area and a vibrating feeder ensures the feeding of the packaging machine. In these configurations, the operator works on a platform.
 

• Loading by pendulum bucket conveyor

The most common application for feeding fragile bulk materials to the weigher is the pendulum bucket conveyor. The pendulum bucket conveyor meets all the criteria of the application and is perfectly suited for packaged products. The advantages of choosing this bucket conveyor technology are: high throughput, no product breakage, flow controlled feeding, equipment hygiene and cleanability.
 

• Loading with belt conveyors 

Belt conveyors are an alternative to tilt bucket conveyors but offer fewer advantages. The floor space is larger and the containment (hygiene) is less controlled. Also, the alternative by transfer screw remains possible for products not very sensitive to breakage.

Numerous peripheral options exist such as magnetic detection, handling assistance for your packaged products, sampling, humidity control, nitrogenation of packages and cleaning in place of your lines (CIP)...
