Let us guess, you've got a line down again, and even though you have multiple production lines that all use 10" rotary valves, you can't swap one or use a spare from any other line because...they are different OEMs and they don't fit. Really? They're all the same size though right? Wrong. Each OEM may carry a 10" valve but guess what? They specifically make it a different height so no other valve can take its place so you HAVE to go back to the original OEM for replacements & spares. Running up your inventory and getting pressure from the brass to lower your spending. You would if you could, right? Rotary Airlock's Cross-Fit is the answer.

Last week, we had the opportunity to visit Norfolk, NE with a state-of-the-art soybean facility being constructed. This visit was prompted by a call from a former customer, someone who had worked with us for many years in the soybean industry but had recently started a new job with this innovative company. They are nearing the completion of their brand new facility, and my contact shared some of the challenges they were facing. Despite having already purchased over 35 airlocks for the plant, they needed stainless steel options for several applications due to corrosion issues that the original equipment manufacturer (OEM) did not address. Additionally, the facility had airlocks supplied by four different OEMs, which created a need for spares from a single, reliable source. This is where Rotary Airlock came into play. We were able to provide significant value by offering to be the single source for all of their rotary valves, thereby simplifying their procurement and bringing value to their maintenance processes at the same time. One of the critical improvements we introduced was the standardization of maintenance and replacement parts. Originally, the plant had 7-9 different styles of bearings and seals. We streamlined this down to one style of extractable bearing and two different seal options, both of which are replaceable in-line. This change significantly reduces downtime and maintenance complexity. Furthermore, our new airlocks come with inspection doors, a feature not available from any of the OEMs currently represented in the plant. These doors allow for easy inspection during shutdowns, enabling wear and clearance checks, as well as the removal of foreign materials without the need to uninstall the airlock. This enhancement is particularly beneficial for ensuring the smooth and efficient operation of the facility. The visit to Norfolk Crush highlighted the importance of tailored solutions in the industrial sector. By understanding and addressing specific needs, we can provide innovative products that not only meet but exceed operational requirements. The collaboration with Norfolk Crush is a testament to how industry partnerships can drive technological advancements and operational efficiency. I left Norfolk with a sense of accomplishment, knowing that our contributions would play a vital role in the success of this impressive facility. As the soybean industry continues to evolve, it is partnerships like these that will lead the way in fostering innovation and growth in manufacturing.

A little over 11 1/2 years ago on February 7, 2008, the Imperial Sugar Company manufacturing facility in Port Wentworth, Georgia was home to the most significant local tragedy to date. Fourteen workers were killed, and 36 others sustained severe burns and injuries after a reactive chain of sugar dust explosions. In the investigation report, the U.S. Chemical Safety Board (CSB) found that the dust explosion had started in the enclosed conveyor system below the sugar silos. The initial blast stirred up sugar dust that had built up on the floors and other surfaces, causing a devastating chain reaction of additional dust explosions racing through the buildings. Then fires resulting from the explosions destroyed packing buildings, silos, a palleting building and severely damaged parts of the refinery and sugar loading area. The investigation conducted by the CSB highlighted numerous safety concerns where dust explosions were a severe risk and thus provided a list of recommendations to ensure that such fires and explosions wouldn't occur again. But, what does this have to do with the OSHA or Fire Code? The National Fire Protection Association (NFPA) addresses dust explosion and fire prevention provisions. After several investigation reports and studies, the CSB recommended that the Occupational Safety and Health Administration (OSHA) develop a federal standard to address the increasing workplace hazards found in facilities. Especially where combustible solids are handled, used, or stored, which has the potential to generate or release combustible dust. It was the tragic event at the Imperial Sugar refinery that pushed this recommendation into action. OSHA later announced that they would initiate a rule-making process to develop a federal standard addressing these needs. Fast forward a few years, and a new committee structure was put in place at the NFPA to oversee the standards-making process for these documents related to dust hazards. As a result, NFPA Standard on the Fundamentals of Dust was born. This document provides the following two key points: 1) Basic principles of, and requirements for, identifying and managing fires. 2) Explosion hazards of combustible dusts and particulate solids. This helped place the NFPA policies as the standard for fire safety, who's policies will soon be enforceable mandates instead of just suggested principles. These NFPA principles have an impact on fire inspectors as well. It outlines operating procedures and practices; inspection, testing and maintenance of equipment; maintenance programs and procedures; training and hazard awareness; qualifications and training for contractors; emergency planning and response; management of change; documentation; and management of systems. It's the holy grail of fire safety for production facilities. An inspector/AHJ must be aware of the provisions related to these facilities and confirm that these protection strategies & procedures are in place. They must also recognize that facilities are maintaining those safety conditions for the welfare of the facility and its worker Rotary Airlock has an even deeper place in their heart for these safety standards. Less than 30 minutes from our facility, Archer Daniels Midland Company (ADM) had a silo explosion that took the life of one firefighter, while causing another to lose multiple limbs. Scott V. of Rotary Airlock grew up in the same town as that ADM plant and his father retired as a Firefighter from that same firehouse. Having loved ones that not only knew the lives lost and changed that day but knowing it could have been that family member at one point, weighs heavy on the entire RA Family. That is why Rotary Airlock set out to provide the highest safety standard product we could. Rotary Airlock engineered drop-in replacement valves that meet, and even exceed NFPA standards — paired with a proprietary seal system that eliminates combustible dust leakage, AND a direct-drive available for EVERY SINGLE make & model. Rotary Airlock has a significant focus on replacing EVERY dust-collection valve in America to do their part in the safety of every person possible.

The Basics Before delving into the intricacies of ethanol use, it's important to understand what it is and how it is developed. In its most basic form, ethanol is derived from plant materials, such as corn and sugar. Previously, oil companies would mix a small amount of ethanol into their fuel blends, in a mixture that was referred to as gasohol. Since this mixture can run effectively in any engine, it helped to reduce the environmental impact of the fuel, while also avoiding any major sacrifice in quality. With recent advances though, an even better mixture has been developed. At 85% ethanol and 15% gasoline, E85 has effectively reversed the properties of gasohol. In fact, the U.S. Department of Energy has even gone so far as to praise E85 for its ability to significantly reduce carbon dioxide and carbon monoxide emissions. And, with gasoline supplies slowly diminishing, there has been an even greater push for ethanol mixtures that push the boundaries of how much gasoline is actually required. The Conversion Process In order for plant materials to transform into ethanol, it must undergo a specific process. Ethanol is not naturally occurring in the environment, which means plants need to be fermented and distilled in order to create it. Of course, ethanol has been a component of human society for a very long time, as it can even be found in alcoholic beverages. As previously mentioned, the key to rapidly developing ethanol is to use crops that are high in sugar. Once crops have been gathered to be processed, they are ground up and refined. The refined sugar that is gathered is then left to ferment into carbon dioxide and ethanol, with yeast added to speed up the process. Up until this point, it is basically the same process used to create alcoholic beverages. After the ethanol has been gathered, it is then distilled and purified before it is ready to be used as a bio-fuel. The relative simplicity of the development process helps to make ethanol production considerably cheaper than many other fuel sources. Since ethanol is a cleaner fuel source, it doesn't add harmful particulates to the air when it's burned. Instead, burning ethanol just creates water and a smaller amount of carbon dioxide than other fuel sources. Expanding Production More than 90 production plants have already been established for ethanol, with at least another thirty planned, as well as several expansions and government regulations in certain states have also made a greater push for ethanol to replace traditional fuel sources. Since ethanol can potentially be just as effective as gasoline, it's not a matter of if it will replace gasoline fully, but rather when. With all of the information above covered it is safe to say a few points. One, that the process of ethanol production is not simply a system that can be stopped or paused, as there are chemical reactions taking place. Two, that Ethanol production facilities are in need of specific machinery and production materials that were created with them and their processes in mind and three, the Ethanol Production industry is only going to grow which means more production and more competition in the marketplace. If we look at these distinct points its not hard to see why Ethanol plants are experiencing excruciating amounts of frustration with valves not intended for their application. Theses valves were designed and engineered to fit within systems but haven't been engineered to prevail within the Ethanol application. These original valves are not intended for what these facilities are producing, their chemical properties, or the people who work there to provide for themselves and their families. Some of these valves are so corroded so quickly they aren't even a valve anymore, but a chute complete with immense pitting and irreparable fissures and breaks. How is a production facility to keep up with the demand if their valves keep failing; shutting down production lines and even come with the expense of ruined product that was stopped part way thru it's process. How are they suppose to compete in a significantly rapid growing industry? Rotary Airlock provides a Master Class option not seen anywhere else. So clients working with them already have a hand on the crown in the growing ethanol industry, but what ethanol facility of the 90 is falling short? Which one's will we see be swallowed up by those who took actions today, instead of hoping for tomorrow? Only time will tell.
