BELTS & CONVEYORS
----
Modular plastic belts: There is now a wide variety of modular plastic belts on the market –manufactured from plastic modules linked together with pins – to suit most applications and products. They are available as straight running, side- flexing or with fixed pitch turn. These belts are positively driven with sprockets that mesh with the belt modules. The module design for each manufacturers belt is, however, unique to them, which means that components and sprockets are not usually interchangeable.
Wire belts: These are made from woven or interlocking strands of stainless-steel wire. Different pitches and wire gauges are available, making them suitable for a range of applications. Wire belts can offer high levels of hygiene and are easy to clean due to their usual high percentage of open area. Wire belts are well suited to use in high temperature applications and for applications where the product needs to drain – for example during enrobing. Wire belts are positively driven with driven sprockets and small transfer diameters are possible, particularly with smaller pitch belts. Wire belts are either straight running or for curves belts of a fixed turn radius are available.
Keep your cool Steel belts have been used in the production of chocolate, candy, bakery and other confectionery products for almost 100 years, with applications ranging from simple conveying to continuous processes such as cooling/solidification, conditioning, casting, freezing, baking and finishing.

One energy bar producer has significantly increased the lifetime of its belts used on a production line for sticky energy bars. Due to the high protein content, the energy bar mass
is extremely sticky. On the cooling line four belts are employed – one after another, and in order to prevent the sticking on the belt, cacao butter was used. The original belt used in this application needed to
be replaced on a monthly basis due to its poor release properties. Even after extensive
daily cleaning of the belt, it was not possible to remove all residue after just one month in
operation. In addition, an operator needed to be available to watch the line on a regular basis in case residue started to build up on the belt. In a bid to find a better conveying solution, the
company turned to Habasit, which was able to suggest a solution with better release properties, which has increased belt lifetime for the application to three years, outperforming the original belt by 36 times! Further, the producer found that it no longer needed to use cocoa butter to lubricate the belt and operators were relieved of the task of keeping surveillance on the belt to check for build-up. Another benefit noted by the producer was that the cleaning process has been reduced by an hour each day.
