Imagine that you are the owner of a warehouse and storage unit. One of the many problems that they incur is how to move items around the facility. Large bulky items are fine, you can just use forklifts, and the same is true for mid-range items as well. There are always pallets for that. However, it’s very difficult to lift up powder on forklifts. The powder tends to not stay on the forks, plus it’s difficult to get it into the vats it needs to be stored in. More importantly, the powder can become mixed with foreign contaminants, like dust and human hair, which makes it useless. How does the warehouse manager move the powder? The answer is they use Pneumatic conveying systems like the ones from https://www.aptech.uk.com/pneumatic-conveying-systems.
Warehouses that store powder usually specialises in the field. Powders are stored and kept sterile so that they can be used in pharmaceutical and medical sciences and supply. However, they can also be used in the transportation of foodstuffs as well. Oats, wheat and flour all need to be kept free of outside materials; otherwise, they cannot be used.
Pneumatic conveying systems are also known as material handling systems. These are specifically for products that need to be handled without humans or other things (like forklifts) touching them. Essentially, they are giant air cannons that fire the material from one end of the place to another depending on where the warehouse manager wants them.
