Smooth flow for cereals

04 December 2015

One of the UK’s leading breakfast cereal brands turned to Spiroflow Ltd for a streamlined transportation process for taking cereal ingredients to three lines of process hoppers via multi-outlet conveyors. For breakfast cereal manufacturers, preserving the integrity of ingredients between the processing stages is absolutely crucial.

In order to minimise degradation and avoid waste, cereal manufacturers require conveying systems that can get the product from its raw state to mixers or packaging machines as gently and as efficiently as possible. For cereals that have to travel dust-free over long distances and complex routes within an operating plant, flexibility and totally secure handling are required from conveying equipment. 

Spiroflow manufacturers a full range of equipment for handling dry bulk solids and ingredients in powder, granule, pellet and flake form across the whole spectrum of process industries.

Spiroflow designed an innovative, enclosed conveying system for a customer once they had assessed their needs and their factory’s layout.  To maximise floor space at the plant, they utilised the T6 Bulk Bag Discharger, which is a fully self-contained unloading station with integral hoist for dust-free and controllable bulk bag emptying, connecting directly to a feed screw that doses product into a mixer. At this point, different ingredients are added into the mixer via a sack tip station. The base of the mixer is connected to a triple inlet screw which takes product to three intermediate hoppers located on a mezzanine above the three process lines. From these holding hoppers, multi-outlet flex screws feed the three process lines, each with 30 discharge points. Isolation valves at each conveyor outlet shut off feed when a process hopper is full, or if maintenance is required.

This particular type of conveyor suits the transport of powdered, granular and flaked materials to a maximum distance of 20 metres, although multiple units as used in this application can extend to greater distances. The main advantage of the flexible screw conveyor is its simplicity, which results in short installation times and low maintenance as the whole system can be stripped down for cleaning within minutes. And as it is a mechanical system, there is no separation of mixed ingredients, which is an essential requirement in any food process. 

The conveyor has the highest levels of hygiene and dust containment for the transportation of delicate ingredients including oats, wheat, rice and corn within a factory, from their raw state through each production stage before being transformed into clusters, loops, puffs and flakes to ensure that the end product is in perfect condition for distribution.

“Our customer wanted fully automated, time-saving conveying equipment that would maximise production,” says James Podevyn, Spiroflow’s UK and Ireland Sales Manager. “The flexible screw conveyors have helped reduce manual handling and degradation of the product during the process, saving time and money.”

When it comes to the challenges for transporting dry bulk solids, whether that’s powder, granule, flake, pellet, bean, lump, shaped or extruded – and in any quantities – Spiroflow aims to offer the breakfast cereals and snack food sectors the best solution.
