Ishida Stops Rejects

The installation of two Ishida multihead weighers and two checkweighers at puff pastry manufacturer Cansimag France SA has halved the rate of product breakages as well as increasing weighing speed
and accuracy.
Cansimag France SA manufactures salted, pure butter puff pastry both flat and twisted. The light, flaky texture of puff pastry snacks is one of the products chief attractions.
However, this fragility presents a handling challenge during weighing and packing.
To solve this, the two multihead weighers are mounted side by side over vertical bagmakers. The weighers are special 12-head models for fragile products, with each of the pool hoppers located above a pair of weigh hoppers, making 24 weigh hoppers in all. Each pool hopper discharges into either the left or the right of this pair, making the arrangement compact and minimising the distance the fragile product has to fall.
On release, the product meets a lining of impact-absorbing plastic in the discharge chute. The chute is at a shallow angle to reduce impact.
Cansimag reports the rate of breakage of the twisted products is now just two per cent, half of what it was on the old line. The reject rate is less than one per cent.
