Selecting the right conveyor belt is of vital importance for most companies that operate in the food processing industry. Thereby, one of the most important aspects of such a conveyor belt is that the food does not stick to the belt itself. In other words, they need a non stick conveyor belt.
The history of conveyor belts
Although the conveyor belt is now taken for granted in almost every production line, this important invention has had a long and vibrant development over the centuries.Contrary to the invention of the light bulb, the creation of the conveyor belt cannot be attributed to a specific date or a specific inventor. The term “conveyor belt” is persistent and does not want to be defined precisely. According to the Encyclopedia Britannica, it simply means, “One of many devices that offer mechanically moving material, like in a factory.” Or, in other words, “The technology of continuous transport”. The term continuous production simply means that a factory’s machines and workplaces are arranged according to the technological production sequence. It is not strictly necessary to use conveyor belts in this process. The logical consequence of the idea of continuous production are production lines. Using these conveyor belts, the material is transported from one production station to the next. As a result, the individual stations depend on each other when it comes to timing, which means that the conveyor speed must be perfectly coordinated. Each workstation must be designed so that the process progresses at the necessary intervals, known as the cycle time. Today, many companies supply a wide range of products with non stick properties, including PTFE conveyor belts, silicone glass fabric and shrink tubes. Thereby, materials with excellent anti-adhesion properties combined with a high resistance to heat and chemicals are used for the non stick conveyor belts. This type of conveyor belts prevents the food to be processed from receiving hygiene problems and diminishes the chances of the food moving on the belt thereby potentially influencing the efficiency.
For what are non stick conveyor belts used?
The hygienic, non stick conveyor belts that are used in the food industry are made of Polyurethane (PU) and are particularly suitable for the wet or dry transport of food. These PU non stick conveyor belts are flexible so that they cannot only be processed efficiently in machines, but also design them in such a way that they are easy to clean and disinfect. The PU non stick conveyor belts are easy to disassemble, so that contamination can be easily prevented. The hygienic, non stick conveyor belts are primarily intended for the internal transport of unpackaged perishable products such as the following:
The hygienic conveyor belts ensure that, due to the element of not having food stuck to the belts, food safety risks can be kept to a minimum. The conveyor belts are resistant to water, chemicals and oil, and they are also durable and cut resistant. Due to the homogeneous structure of the PU non stick conveyor belt, delamination (loosening of several layers) is impossible.
