Conveying flour – Choose the Right Conveyor

If you are looking to convey flour in your factory process and you are unsure which conveyor will be right then read our guide to choosing the right conveyor below.

Flour is a powder product which is made by grinding raw grains and roots and is then used to make a final product such as bread, dough, cakes etc. Wheat is the most common base of flour however other types such as corn flour and rye flour are also used throughout the world. Cereal flour is also common as well as meal, which has slightly coarser particle sizes than flour. As flour can come in many different variations it can also present a series of challenges such as hygiene, dust containment, blending and batching which we will discuss with each conveyor system.

CHOOSING A CONVEYOR FOR FLOUR

Flexible Screw Conveyors

The flexible screw has only one moving part, the spiral and as it constantly remixes as it conveys so it is ideal for conveying flour. Depending on what type of flour you use will depend on which spiral will be most beneficial but for standard flours the flat screw would work the best. The flexible screw in the tube will move round in a  spiral and will convey the flour even at an angle. This type of conveyor works well on products such as flour where degradation is not an issue. This conveyor can come with a drop out trap, quick release flanges and a reverse bung which helps to make it a very hygienic flour conveyor. If you often switch batches of flour in your process this conveyor would be ideal because of its hygienic capabilities it will reduce cross-contamination of different flour types.  Watch our video about the hygienic FSC and how it could help you with your process.

Aero-Mechanical Conveyors:

The Aero-Mechanical conveyor creates an airstream which moves the product up the tubes along with high-speed discs and a rope. The flour is conveyed in the air stream created by the rope and discs in the tube where the product is handled gently. This conveyor is ideal for flour products where degradation is a concern. This conveyor is a great choice for conveying flour because any dust created during conveying will be contained within the conveyor. This will reduce the risk of explosions caused by static build up and the conveyors can be ATEX compliant.
