In some cases, there is only one way that a product or substance can be transported safely and without causing contamination issues. For example, when a warehouse deals with substances like animal feed, small medical pills like paracetamol or even a liquid or a gas, the regular moving strategies will not work. Therefore, an alternative method needs to be found and Vacuum conveying like that from https://www.aptech.uk.com/pneumatic-conveying-systems/vacuum-conveying is the answer.
Vacuum conveying is the only natural way to move products and certain raw materials. This has to be via a system of pipes and tubes. These tubes and pipes are hermetically sealed. This means that nothing can get into the pipes that would cause contamination of the product. However, this is vitally important if the substance needs to be sterile. For example, dust and dirt, or virus particles breathed out by humans, can be fatally damaging to the product and substance, meaning that the whole lot may have to be dumped. This is a terrible cost to bear for any company.
How the system works is by the manipulation of air pressure. This can be controlled so that the “push” of the air is gentle or more forceful, given the nature of the product that needs to be moved. A vacuum is an absence of air. This void pushes the product around the tubes, almost like a bubble of nothing. However, it is strong enough to force gases and feed along the pipes to where they need to be.
