When food processing plants need to convey material over distances greater than 1,000 feet, mechanical conveying is considered the preferred method. Pneumatic conveying, it has traditionally been thought, is too impractical and expensive for such applications.
However, mechanical conveying only works in applications where contamination isn’t a concern. When contamination must be avoided, pneumatic conveying is the ideal method of transporting material. So, while uncommon, can pneumatic conveying systems work across distances of 1,000 feet or more? The answer is yes, but it requires careful consideration of multiple factors, including material, temperature, pipe diameter, and the size of the blower motor. In such cases, it is ideal to work with the blower manufacturer to ensure that the system has the necessary amount of power to handle the distance without damaging the product.
This article will explain the basics of building a pneumatic conveying line that can traverse more than 1,000 feet while mitigating potential technical problems.
