Industrial Utility Efficiency

# System Assessments

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.

## When Planning Efficiency Upgrades, Don’t Ignore Vacuum - Reduced Power Consumption and Utility Incentives Drive Cost Savings

Electric utility incentive programs encourage industrial and manufacturing companies to reduce power consumption by paying part of the cost to upgrade to more efficient equipment. It’s a great concept, but many customers only go after low-hanging fruit, such as upgrades for lighting or air compressors, and go no further.

## Reducing Demand in Industrial Vacuum Systems

This article will focus on optimizing the demand-side so the centralized “supply-side” (the vacuum pumps and controls) can then run at a lower energy and maintenance cost. First, I will start with a simplified model of a vacuum pump system demands. See Figure 1 for a one-pump/one-demand simplified system. See Figures 2-6 for some typical controlled and uncontrolled demands. The symbol with the three lines is an orifice, a hole essentially. I am defining three types of system demands adding up to the total demand on the vacuum pump.

## Republic Manufacturing Delivers Food Grade Blower & Air Knife Systems

Blower & Vacuum Best Practices interviewed Republic Manufacturing VP of Sales & Marketing, Rich Leong.

Our line of regenerative blowers, also known as side channel blowers, are for vacuum or compressed air applications in both horizontal and vertical mounted positions. Airflow capabilities range from 50 to 776 CFM, vacuum capabilities from 47" to 236" of water (1.7 psi to 8.53 psi) and pressure capabilities up from 47" to 307" of water (1.7 psi to 11.09). TEFC electric motors are cUL and CE certified and come in single and three-phase, dual frequency and multi-voltage versions for worldwide applications. Horsepower ranges from 1/2 to 40 HP (from 0.4 to 30kW).

## Suttero Bazenheid Advances Meat Processing to Energy-Efficient Centralized Vacuum System

Energy for the entire Ernst Sutter AG company – and consequently the Suttero Bazenheid premises as well – is generated via hydropower. In addition, around 75% of the energy from refrigeration is also used to generate hot water. When creating vacuum for packaging, Suttero Bazenheid relies on a centralized vacuum system from Busch. This is significantly more energy-efficient in operation than decentralized vacuum supplies on individual packaging machines. As a result, Ernst Sutter AG has created a production plant that corresponds to the latest standards, both from a technical and ecological perspective.

## Calculating Most-Open-Valve Aeration Control

Most-Open-Valve (MOV) can be a cost-effective way to optimize aeration energy. It can also be a confusing and troublesome addition to a process automation project. In my experience MOV is the least understood aspect of aeration control. This article will shed light on MOV, the process and energy impacts and why it’s worth the trouble.

## Rotary Screw Vacuum Pumps Benefit Meat Packaging Plants

Meat packaging plants have long used vacuum pumps as a way to remove air and reduce the amount of oxygen in their products’ plastic packaging. Vacuum packaging extends the meat’s shelf life while protecting its flavor and exposure to outside elements, such as freezer burn and bacteria.

## Custom Blower and Air Knife Bin Drying Solution Reduces Packager Labor Hours

At Scholle IPN, Valley Packline’s engineering experience and JetAir’s drying expertise came together to deliver an automated, energy efficient solution. Ultimately, the new system eliminated 120 man-hours each week dedicated entirely to erecting and washing. The new system can be manned by just one employee as it pulls bins directly off delivery trucks, re-erects, washes, and dries them, and feeds them into the facility for refilling. Throughput at Scholle was improved by the system, while energy costs were kept to a minimum.

## Beware Dense Phase Pneumatic Conveying Running as a Dilute Phase System

This article reviews two common pneumatic conveying system types and the importance for each operating plant to know their design and operating parameters particularly conveying air flow velocity and particle velocity profile.

## Modern Woodcrafts Automates with Robotic Arms and Intelligent VSD Vacuum Pumps

The integrated process that leads to perfectly finished components begins in the plant’s new material store. “One way we’re staying at the leading edge in our market is by researching the latest innovations and choosing the best machine for each process,” Legere explains. “Our new material store, operational in June 2017, is one example. It combines a physical data base of sheet goods with a robotic arm that handles materials and presents them to a cutting machine for processing. After a few minutes, a finished part emerges. All of this occurs with zero human interaction.”
