Spiral Belt

Spiral Belts are a type of conveyor belt that are primarily used in the food production and processing industries. Radius belts in straight applications as well as in curved applications and  especially in Spiral Towers.

Where Spiral Belts differ from normal conveyancing systems is that they are able to turn the food products – or other products – around corners. This is because the inter-locking nature of the spiral links that make up the system can flex and twist to accommodate curves. Conveyor belts in industrial applications go back to the late nineteenth century but nowadays sophisticated systems, like spiral belts, are used in a huge variety of applications with better efficiencies than ever before.

Spiral Belts in Food Production

A typical application for Spiral Belts in a food production setting is to cool or freeze a large number of products.  Ad the end of a processing line before storage, or between processes, for instance between baking/frying and packaging.  The spiral construction allows optimal airflow around the product.

As such, they are commonly put to use in automated bakeries, meat production plants, potato and vegetable production units and non-food production. This type of belt is designed for low-tension spiral applications. This includes proofing, pasteurizing , cooling and freezing spiral towers.  Our belts in the food industry are mainly executed in stainless steel AISI 304 and AISI 316.

Wide and Narrow Spiral Belts

Another type of spiral belting is the Balanced Weave Wire Mesh straight running Spiral Belt. They offer a design that has a large range of dimensions. They are available to convey a huge variety of products. The woven belts will be fitted with left or right handed spirals so that the belt is balanced. Wide spiral belts are commonly connected by a system of crimped cross wires. The Belts are used in food production but also a lot in the chemical and glass manufacturing industries. They are also often used in washing and dehydrating connveyance systems. Wide Spirals belts usually need to be driven  by a plain roller and put under tension by a system of guidance and tensioning rollers. Further more Esfo has a special range op Wide Spiral

Belts which can be driven by sprockets. Rollers with little teeth stick into the belt and drive the belt forward The pre-tension can be low.

What to look for

If you are looking for advice making curved conveyor there are certain things that are worth checking with the manufacturer for before committing. These include a rugged and durable frame which is designed for heavy use that will not wear out quickly. You should also keep an eye of the efficiency of the design as this lessens the amount of power the system uses as well as the life-cycle costs.
