Tubular Drag Conveyor

The Fight Against Contamination in the Food Production Industry


Contamination is a constant threat in the food production industry and one that must be guarded against at all times. Every piece of machinery that is meant to be used in the industry must account for this fact at a basic level, with designers being tasked with ensuring that every decision they make contributes to the greater goal. This is true not just of equipment that actually transforms raw materials into finished food products but also of all the associated supporting tools. Tubular conveyor systems, for example, are designed to fight food contamination in a number of effective ways.

The most obvious and visible of these is the one that gives them their name. Every such system includes an enclosing shroud that entirely covers the conveyor line, with many being essentially airtight from end to end. This relatively simple measure allows manufacturers to virtually guarantee that food will not be subjected to contaminants in the air as it moves from one station to the next and is therefore a valuable measure in its own right.


Tubular belt conveyor designers have plenty of other tricks up their sleeves, though. As food moves from one place to another along a manufacturing line, it is invariably subjected to stresses. Over time, these forces will almost always result in the accumulation of detritus, dust, and other waste. While this is almost an inevitable fact of food manufacturing, this situation cannot simply be accepted at face value. Waste of this kind that is allowed to build up for too long, after all, becomes another kind of contamination to worry about, so preventing accumulation should always be a priority.

Tube-based conveyor setups therefore typically include a number of ways of working toward this goal. Most designers take great pains to ensure that all moving elements are shielded as well as possible, reducing the surface area that must necessarily contribute to the production of dust and waste. Most systems also include several ways of removing built-up waste without overly impacting production efficiency, so that regular cleaning can be smoothly worked into the everyday processes at a given plant. Fighting contamination is a constant need in the food production industry, but there are plenty of good tools for doing it with.
