Spiroflow has launched the Chainflow tubular chain drag conveyor, which conveys dry powders and granules – particularly fragile materials such as coffee beans, cereals, nuts, dried fruit, grains, dry soup mix and baby formula powder.

Configured in a loop or circuit, strong 304 or 316 stainless steel chain is fitted with moulded UHMWPE discs. It provides maximum chain life while gently moving fragile products through a homogeneous crevice-free conveying path. The conveyor has a drive assembly at one end of the circuit and a return housing, fitted with an automatic tensioner, on the other end of the circuit.

Processors can achieve intricate layouts with multiple inlets and outlets in complex three-plane circuits. The conveyor can be cleaned in place and is engineered to run continuously.

It delivers fast and efficient conveying with capacities up to 10.5m3/hour (370 ft3/hour). Processors can convey over long distances with maximum straight line lengths of up to 76m (250 ft) per conveyor and link multiple conveyors for longer distances.
