The 2022 International Production & Processing Expo (IPPE), was held January 25-27, 2022 in Atlanta with more than 500,000 square feet of exhibit space and 1,140-plus exhibitors. Attendee numbers had not been released when this was written. Sponsored by the U.S. Poultry & Egg Association, American Feed Industry Association and the North American Meat Institute, IPPE is the world's largest annual poultry, meat and animal food industry event of its kind.
In choosing a system for the safe, clean conveyance of materials, it seems that the choices can be remarkably complex. Prior to such a choice, a facility is usually operating with, live personnel, open conveyor belts and implements such as buckets. While employees may be protected by proper clothing, masks and goggles, materials are exposed to air and dirt, waste is a constant worry, and expensive equipment is endangered by particulates that can slow or jam it.
This article aims to discuss the various technologies of equipment that could be presented to a wastewater operator faced with a temporary need for blower air and to help the operator understand the impact (both monetarily through a “Total Cost of Rental” approach and environmentally) of their decisions.
By using state-of-the-art vacuum technology for degassing mineral water, it has been possible to save an average of 3,000 cubic meters of water per filling plant per year. The solution was to replace the existing liquid ring vacuum pumps with MINK claw vacuum pumps from Busch Vacuum Solutions.
In an ongoing project to improve processes whenever and wherever it can, a global manufacturer of private label retail, food service and specialty brand teas, purchased an extension conveyor system to improve efficiency and ergonomics. Prior to implementing the extension conveyor, a vacuum conveyor system transferred raw materials into portable silos that workers rolled from one production machine to the next.
The food industries can have many messy processes, whether it is poultry evisceration, deboned waste conveying, bottling, or sugar cake filtration. Liquid ring vacuum pumps (LRVP’s) are often utilized as the backbone of these processes because they can handle the soft solids, debris, and particles that can easily get sucked into the vacuum pump. So how does a LRVP work, why does it work in these processes, and how to make sure they keep working?
A small site located within a floodplain, prone to erosion, and currently occupied by an existing in-service wastewater treatment facility is not at the top of any engineer’s list for a desirable site to expand a wastewater treatment plant or reclamation facility. However, these challenges created opportunity for specialized solutions during the design of the facility expansion; in particular, in designing the aeration and digester blower system.
Ever since it was commissioned in 1974, the Echallens wastewater treatment plant in the Swiss canton of Vaud has been generating power from the recovery of biogas. In May 2020, two old oil-lubricated piston compressors used to mix the sludge in the digester were replaced by one MINK claw compressor from Busch Vacuum Solutions. This enabled the amount of power required for this process to be reduced by up to 40 percent. For the director of the treatment plant, this means he needs less energy to produce energy.
Wintek Corporation was contacted by a plastics manufacturing company in the summer of 2015 to evaluate their process vacuum capabilities. The customer was looking to replace a recently purchased used vacuum system to be used in a PET solid state polymerization/drying application. The process required high heat and vacuum and needed to run at 1 mBarA (0.75 Torr). The customer had purchased the dryer and accompanying vacuum system from an overseas supplier. While they were happy with the dryer, the vacuum system was not delivering the desired performance.
Aerobic digestion is a common treatment technology used at small-to medium-sized wastewater treatment plants for the treatment of waste activated sludge (WAS). The objective of aerobic digestion is to treat the sludge for disposal, and for those trying to meet Class B biosolids, further reduce volatile solids (VS) and pathogens to ensure the sludge is suitable for land application.
When the plant’s original aeration blowers became costly to operate and newer technology offered the promise of energy-savings, Fuqua took decisive action and replaced the older blowers with high-speed turbo blowers. As a result, the plant saves ratepayers approximately $30,000 per year in energy costs and bolsters the plant’s ability to maintain uptime and achieve extremely clean effluent.
