Biscuit Lump Breaker


The client had been previously using a Sievmaster Rota 200 machine but sold their existing business. They restarted another business but this time they required twice the throughput originally produced. Machine was used to break biscuits down to a crumb suitable for use in cheesecake bases.


The product was lifted and tipped directly from Dolav type containers then fed onto a swan neck cleated belt conveyor via a small intermediate hopper.


Farleygreene supplied a Rota 400-ST centrifugal sifter which provided twice the throughput of the original Rota 200 machine, because of its double auger and paddle blade configuration. The feed hopper was modified to provide a moderate sized bulk hopper and the unit was mounted upon a stainless steel stand. Farleygreene also supplied the lifting and tipping unit to feed the sifter, along with the belted conveyor to take the product away for packing.

The Sievmaster Rota was fitted with a perforated mesh basket which creates a grating effect to the biscuit, grinding it down to the size required. Biscuits, being of a high fat content, can clog a normal grinding system but the action of the blades prevent this and allow for very fast production.


Impressive production rates achieved. Client was provided with standalone system without the need for him to source various machines from alternative suppliers.
