The dried flakes shown above needed a reliable method to convey between the large sacks in which they’re delivered and the boilers into which they need to be added. The existing operation has been to have personnel cut open the bags and pour them into the boilers, but this method is taxing for the workers and results in significant fatigue throughout the day as well as spillage around the boilers. This facility needed a better way to move the corn flakes that was small enough to fit within the confined workspace and capable of quickly emptying the sacks over a distance of ~6.5 ft.
This customer requested that the solution be made of 316 grade stainless steel, and that implementation and use be as simple as possible. With a bulk density of ~40 pounds/cubic foot, and merely a desire to move the material as fast as possible over this short distance, I directed them toward our 3” Stainless Steel Line Vac made of 316SS. To increase the conveyance in the application I also offered our service to convert our standard model 6066-316 Line Vac to a “High Power” unit by increasing the size of the generator holes.
Both of these solutions were deemed as viable because they both allow for fast emptying of the bags (we estimated between 1-2 minutes to completely empty a bag), little-to-no spillage, and far, far less fatigue on the workers in this area (the key driver for searching out a new method of material transfer.
The potential model numbers were presented to management for a purchasing decision. As this project moves forward, and even after the solution is installed, we’ll be available for product assistance and engineering support. If you have an application in need of a viable pneumatic conveyor, contact EXAIR. We’ll be happy to explore the application and offer any potential solutions.
It is a very sad day for me at EXAIR… No, I’m not retiring or leaving the company, but today is my last day to write about Plant Engineering Product of the Year Awards…for this year. It has been quite an honor to write about four of our best innovations from the last year over the past weeks. In case you missed the entries, you can click on the these links to read more about our other 2013 award winners: 316 Stainless Steel Dual Cabinet Coolers,1 Inch Flat Super Air Nozzle or the Heavy Duty HEPA Vac. Today’s post is about the No Drip External Mix Atomizing Nozzle, which the readers of the Plant Engineering magazine bestowed the gold award for fluid handling products. EXAIR’s Liquid Atomizing Nozzles combine the liquid of your choice with compressed air to create a mist of atomized liquid. The external mix nozzles have the highest liquid flow rate of any of EXAIR’s Liquid Atomizing Nozzles with flow rates up to 60 GPH. They are a great solution for applications where independent air and liquid control is required. Additionally, more viscous fluids can be used with the external mixing of the nozzle than either the internal mixing or siphon fed nozzles. External Mixing Nozzles can be used to atomize liquids up to 800 centipoise. In addition to the benefits of the external mix atomizing nozzle, this spray nozzle features a valve to positively stop liquid flow, when the compressed air drops below 30 psig. Any time you need to maintain a smooth finish or are spraying an expensive liquid, the no drip function can be invaluable to preventing rework, and ensuring a quality finish on each and every product. The EXAIR no drip function is patent pending and does not require an additional air line to control the no drip mechanism, simplifying installation and functionality.
EXAIR Cabinet Cooler Systems are used continuously in some of Industry’s harshest environment to protect crowded, overheated, and expensive electronic controls from heat failures and alarms. Dual 316 Stainless Steel Cabinet Cooler Systems provide 5,600 BTU/HR of cooling through (2) electrical knockouts and a compressed air line. The 316 Stainless Steel NEMA 4X Cabinet Cooler Systems are UL Listed for wash down environments for food service and pharmaceutical application.
Fans, air conditioners, and heat exchanges use ambient air and are susceptible to failure from dusty environments when the filters clog or mechanical components fail. With no refrigerant, motors, or bearings, Cabinet Cooler Systems require no maintenance and can run for years or decades. Cabinet Cooler Systems prevent downtime on the most critical components in your facility.
These coolers are used to protect the most sensitive electrical components in the United States. A customer disposes of chemical weapons and monitors the exhaust gases of their facility with electronic components mounted to the outside of the smoke stack. This enclosure is exposed to the elements and the heat of the desert sun. Any failure or alarm in the equipment forces the process to shutdown. A Stainless Steel Cabinet Cooler System protects these electrical components from overheating.
Stainless Steel Cabinet Cooler Systems have been used on ships, power plants, medical device manufacturing facilities, and bakeries to keep heat out of their enclosures. They also feature an added benefit that fans, air conditioner and heat exchangers don’t. The EXAIR Cabinet Cooler Systems apply a positive pressure to the enclosure to push out any dust that may otherwise gather inside your cabinet. This positive pressure improves air flow and limits dust building up on electrical components. When dust collects on components, it acts as an insulator trapping the heat against your critical controllers. This trapped heat can lead to premature failure even with sufficient cooling inside the enclosure.
As this spring heats up and summer begins, keep the Cabinet Cooler System in mind as great solution to your over heating issues.
