The 2019 WEFTEC Technical Exhibition and Conference was held September 23-25 at McCormick Place in Chicago. The event featured 148 technical sessions, 27 workshops, 16 mobile sessions, seven local facility tours and 1,000+ exhibitors.  Both Blower & Vacuum Best Practices and Compressed Air Best Practices® Magazines were pleased to be in the literature bins at the 2019 WEFTEC!

The right vacuum solution not only ensures product quality in meat processing operations; it  also helps companies achieve important sustainability goals. Such is the case at two leading meat processing companies in Germany, both of whom added Busch Vacuum Pumps and Systems solutions to their operations and saved energy and more as a result.

Finally, a test code has been created that will provide accurate performance comparisons for both positive displacement and dynamic (centrifugal) blowers. ASME PTC 13 provides procedures for determining the required total operating electrical power of a packaged blower system, termed the “wire-to-air” performance. Here’s a review of PTC 13 and considerations related to this important standard.

Vacuum can be used in many ways for the meat processing and packaging industry. From mixing ingredients to evisceration (removing organs, excess fat, bones, etc.), to the washing/preparation of the meats or even in the packaging of the meat itself, vacuum is critical to the industry. 

One of the most exciting technologies impacting the ability of end-users to optimize blowers at their wastewater treatment plants and manufacturing operations is controls. Blower & Vacuum Best Practices interviewed Tim Hilgart, of Howden America, to get his perspective on blower controls technology and its application.

Distillation, degassing, drying, filtration, membrane separation, adsorption, and crystallization are all among the separation processes that rely on the differences in the physical properties of substances in a mixture. Distillation relies on the differences in boiling point or in vapor pressure versus temperature characteristics. Heating, evaporation, and condensing are the tools used in distillation that separate the liquid constituents in a liquid mixture.

A major challenge our customers face is the way bulk materials are supplied to the market. We needed a material handling system that would keep up with our demand, ensure worker safety and limit manual manipulation of material. The VAC-U-MAX team designed and manufactured a material handling system capable of conveying over four and half million pounds of powders per year that now allows us to continually meet our growing business.

In the first of this two-part series on the basics of aeration control valves we examined valve fundamentals and basic equations for analysis. Here, we look at interactions between valves and discuss new flow control technologies.

Many heat-treating applications put difficult demands on vacuum pumps in general and oil-sealed pumps, in particular. Byproducts from the heat-treating process can contaminate the vacuum pump oil and create higher vapor pressures that cause deteriorated vacuum levels in the heat-treating chamber, or buildup and blockages in the pump mechanism.

In 2010, the American Society of Mechanical Engineers (ASME) established the PTC 13 Committee to establish a power test code for all blower technologies. Blower & Vacuum Best Practices Magazine interviewed Committee Chair Jacque Shultz, HRO-Turbo Product Technical Leader, Howden North America, Inc., for an update on the new code.

Sizing, selection, and adjusting control valves often causes confusion for process and control system designers. Improper valve application can cause operating problems for plant staff and waste blower power. Basing the airflow control system design on fundamental principles will improve valve and control system performance.
