Pneumatic conveying via a closed system can help your process operate in a way that eliminates exterior contaminants, preserves the hygienic environment of your process, and extends the life of your existing equipment, all while efficiently, reliably, and safely transferring your powder from one location to another. Here are the benefits of pneumatic conveying regarding plant and equipment cleanliness:
It is a common practice to manually transfer material into a vessel. Surprisingly this occurs in some of the most modernized workplaces. This involves operators lifting and dumping containers of powder directly into the reactor. With mechanical equipment there is more automation involved, but the cleaning of conveyor belts poses a constant problem that is difficult to solve due to particles adhering to the belt as well as material build-up on the rollers. Most pneumatic conveyor designs, on the other hand, enable easy access to the filter design for cleaning, inspection and change out. Whether it is housekeeping requirements for sanitation or general cleaning between batches, pneumatic transfer systems need less maintenance and offer a cleaner way to transfer than manual and mechanical methods.
A closed system, meaning a system that prevents the product from becoming airborne and entering the environment, will substantially reduce equipment and facility clean-up time. Since less labor is required to clean and maintain cleanliness the cost-performance ratio of the system is improved, providing significant savings over other transfer methods.
Contamination can mean one of two things in a process. Depending on the properties and characteristics of the material being transferred, there is the concern of contaminating the product with exposure of environmental elements (e.g. oxygen, human contact) that can have an adverse effect on the product’s purity. The flip side of that scenario is the risk of contaminating the environment with the product, in the case of hazardous or explosive materials. When it comes to exterior contaminants, product residue that comes in contact with the exterior of the equipment can create an unhygienic situation that can lead to corrosion which, over time, can become a serious problem that negatively impacts the performance of the equipment. Pneumatic conveying extends the life of equipment by keeping the material and environment separate from one another, minimizing corrosion through the elimination of exterior contaminants.
