The basic function of vacuum degassing is to remove the vaporized gas and moisture from the extruded material. During the extrusion process, as raw materials melt under heat and pressure inside the extruder. The polymer chains and chemical compositions are going through changes, and a variety of gases are released.

Get the Most Out of Centrifugal Blower Control Upgrades

Single-stage centrifugal blowers are a proven technology that have been around for many years and will probably be here for many years to come. A well maintained machine can last for decades and will likely outlast its original control system. Even if the control system is still in good working order the components might already be end of life and hard to replace if any of them fail. If you are thinking about modernizing the hardware (PLC / HMI / Instruments) this is also a great opportunity to make the system a little smarter and user friendly. 

Measuring Blower Airflow Rates with Calibrated Ammeters

One definition of “calibrate” is “to determine, rectify, or mark the graduations of something”. An ammeter is an instrument for measuring electric current. Therefore the simple definition of a calibrated ammeter is a current measuring device marked with units of measure, presumably amperes. In the blower industry, however, the term has developed a specific meaning. A calibrated ammeter is an instrument that measures a blower motor’s current draw and converts the measurement to a display of blower airflow rate. 
 

Show Report: Vacuum Technology at 2022 AISTech

The 2022 AISTech Conference and Exposition was held May 16-18 at the David L. Lawrence Convention Center in Pittsburgh, Pennsylvania. It was the conference and exposition’s most successful year yet with more than 8,000 attendees. The event featured 300+ technical presentations and 500+ exhibitors, featuring the latest technologies in iron- and steelmaking from all over the world. AISTech 2022 also gave away a brand new, fully loaded, 2022 Chevy Silverado Truck to one lucky attendee. Both Blower & Vacuum Best Practices and Compressed Air Best Practices Magazines were pleased to be in the literature bins. 

Vacuum Solutions for Plastic Recycling

More than 300 million tons of plastic is produced every year, and much of it ends up causing environmental problems. In response to these challenges, there are widespread global efforts to increase recycling capacity and innovate for more efficient and effective recycling solutions. Vacuum plays a critical role in achieving these improvements.

The 2022 International Production & Processing Expo

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. 

Two Vacuum System Optimization Case Studies from Europe

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.

Considerations for Temporary Blower Air at a Wastewater Treatment Facility

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.

Tea Packaging Quality Improved with Vacuum Conveying Upgrades

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.

Liquid Ring Vacuum Pumps and Food Applications

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?

Design Engineering a WWTP Expansion with Unique Site Constraints

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.
