Production of conveyor belts for the processing of biscuits, sweets, and candy

The industrial processing of biscuits, candy, and sweets in general requires structured and efficient automation in order to support the large volumes of work typical of this field. The conveyor belts are fundamental to the handling of these products—such as many others in the food sector – along the production line: 

• Inside the cooking ovens, where the products are subjected to high temperatures
• Along the cooling tunnels, where the products are brought to room temperature in order to preserve their quality and features.

The conveyor belts for the bakery

In a very similar way to what happens in the bakery sector, also in the production of sweets and biscuits the most significant problem in the planning of conveyor belts to be used in the production line is the high temperatures reached during the cooking. In the production of a belt for pastry, it is so preferred to use some certified stainless steels for food use, that are able to resist without problems and without being subjected to deformation also at very high temperatures.

The question of the opening of the wire mesh acquires, in the conveyor belts for pastry, particular importance. If the one used in the cooling phase will simply have a particularly wide opening, that allows optimal air circulation and so a rapid and efficient cooling of the product. Instead, during cooking many sweets—especially biscuits—require extremely uniform cooking; to guarantee it is used triple torsion wire mesh with a very close opening, creates such a compact surface in order to ensure an ideal distribution of the heat over the entire product. The application of these wire meshes becomes even an aesthetic function for the final product because the metal wire mesh leaves a characteristic trace and is very recognizable on the underside of the biscuits.

The technical measures are taken by Larioreti for the conveyor belts for pastry

Usually, there is no need to install side plates or lifters on the conveyor belts for the pastry and sweet industry in general, also the Teflon coating is not provided. Instead, is very important, and guarantees from Larioreti, the possibility to dispose of belts the material of which has been certified for food use, in order to comply with any legal duty. Between the technical measures that we use to offer to our customers, a conveyor belt high-performing stands out for sure the attention to the drag, which can be with sprockets only for the cooling phase (where there are no problems with the thermal expansion). As regards the conveyor belts for the cooking oven of the sweets, instead, our experience has shown that a system without a side chain is the one that offers the best performance and best quality.
