Belt Specifications Required

Good grip and release properties, as well as suitability for foodstuffs in general are the top priorities for transferring dough between different stages in the process. Patterned belts can also be advisable depending on the conveying angle. Tiny return radii facilitate release of the dough at the end of the conveyor.

Belt Specifications Required

Good grip and release properties, superb positioning accuracy and suitability for foodstuffs in general are the top priorities for these processes. Straight tracking and incision-resistant surfaces are required when forming and cutting out the dough. Tiny return radii (knife edges) are needed when transferring the formed pieces of dough.

Features, Functions, Benefits

Uncoated urethane or cotton-coated belts are used for forming the dough. Laterally stiff belts with incision-resistant coatings made of PU or polyolefin are the first choice for cutting out and forming the dough. Belt edge sealing (Smartseal) can be applied to many of the belts. These belts’ good release properties minimize the need for flour as a release agent. They are easy to clean and EU and FDA compliant.

Belt Specifications Required

To form the dough using rollers, a belt that’s suitable for use with foodstuffs and with relatively high belt tension is required. In order to transfer the formed pieces of dough to the belt, the belt’s surface needs to create a suction effect. Tiny return radii (knife edges) are required when transferring the formed pieces of dough to other belts. Scrapers are applied to clean the belt surface, which means that the belt surfaces need to be able to withstand wear and tear.

Belt Specifications Required

The in-feed and out-feed belts must be able to withstand high temperatures for short periods of time and have good release properties. The belts are constantly exposed to high temperatures in the oven itself. Tiny return radii are required to transfer the products. The belts must be suitable for use with foodstuffs.

Features, Functions, Benefits

For this application, fabric-based belts (Siegling Transilon) are usually made endless with a 60° Z-splice. This type of splice means that the belt tracks exceptionally smoothly over knife edges. Mechanical fasteners can also be applied. Belt edge sealing can be added too if a very high standard of hygiene is required. In addition to offering hygienic surfaces through and through, plastic modular belts (Siegling Prolink) also come with tiny return radii. All belt types are available with patterns that provide good release properties. They are easy to clean and EU and FDA compliant.

Belt Specifications Required

The belts must be suitable for use with foodstuffs. They need to have relatively heat- and abrasion-resistant surfaces and be able to cope with curved applications.

Features, Functions, Benefits

All Transilon belts for cooling applications are easy to clean, EU and FDA compliant and can come with belt edge sealing (Smartseal). Curved belts with fabric tension members have enhanced fabric designs (e.g. are longitudinally and laterally flexible). They are made of several segments, resulting in a good distribution of force in the belt. Plastic modular belts (Siegling Prolink) are also suitable for straight and curved sections. Often spirals are used for this application. Belt types with a large open area enhance cooling processes in the baked goods and are also ideal for use in very low temperatures.

Belt Specifications Required

The belts need to be suitable for use with foodstuffs and easy to clean. Specific belt characteristics are also required, such as uniform thickness during the weighing process, good grip in order to position the product precisely and good release properties during the labelling process. In the case of metal detectors and x-ray equipment, the requirements depend on the application. In deep-frozen sections, the belt must not become brittle at temperatures down to -40°C.

Features, Functions, Benefits

Special surface characteristics make the portioning and wrapping process easier and more reliable. Special finishes for weigher belts provide extremely precise splices of the same thickness. Antistatic or non-antistatic belts are available for metal detectors, depending on requirements. To ensure safe x-raying, belts with a high friction coefficient on the top face are used so that the equipment’s safety curtain can pass through without the products on the conveyor belt slipping. The food-grade Prolink series, made of polyoxymethylene (POM) or polyethylene (PE), offer exceptionally long service lives when products need to be deep frozen.
