Industrial Utility Efficiency

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.
Many manufacturing processes are like offensive linemen. When everything is running smoothly, nobody tends to notice. But, when an application starts creating a hazardous work environment (think too many blindsided sacks), or the products start spoiling (think shutout or a losing season), you best believe someone will start paying attention.
This item is designed to be used with our Vortron single stage centrifugal blower. Industrial water removal processes are presently being accomplished with several types of systems using 40 PSIG regulated pressures from the 100-125 PSIG plant compressed air supply. We can match and improve the process, usually with required operating pressures below 3 PSIG. This creates a huge reduction in process utility costs. This fixture provides a 360° converging point air impact pattern.
This food & beverage plant is a large (500,000 sq ft) meat processing plant with twenty packaging lines and nine palletizers. The compressed air system is supplied from three separate rooms with seven individual lubricant-cooled, single and two-stage rotary screw compressors. The plant has four blower purge desiccant dryers designed to deliver a - 40°F pressure dewpoint.
Bottling companies and breweries, in California, are benefiting from a three-step system assessment process aimed at reducing the electrical consumption of their compressed air systems. The three-step process reduces compressed air demand in bottling lines by focusing on open blowing and idle equipment, and then improves the specic power (reducing the energy consumption) of the air compressors.
Many times, the hierarchy of making improvements in your compressed air system will begin with the larger equipment. If your compressor is outdated, inefficient or sized improperly for your plant, the cost of replacing it may scare you away from proceeding down the efficiency path. It is also typical to first concentrate on updating the controls of a compressor to best match peak demands and lulls in the need for air and, while this is a very good step to take in your overall plan of attack, it can also burden your budget.  
“Sandblasting” is one of the oldest and most used methods of metal treatment. Various abrasive materials may be loaded manually or by a vacuum system pulling the “grit” from a storage tank. A control valve then operates with the compressed air (bypassing the vacuum pump), being forced into the tank pressurizing the receiver. When the high pressure compressed air goes out the discharge line, it pulls the appropriate amount of grit with it to effectively impinge against the targeted metal surface.
Assessing payback on engineered air nozzle and blower upgrades There are a variety of means factories can use to remove or “blowoff” moisture from a package. Open tubes or drilled pipe are often viewed as simple low-cost methods. However, there are considerable drawbacks to these approaches, most notably – increased operating expense. While they may be convenient and inexpensive in the short term, these approaches often cost 5-7 times more to operate than preferred alternatives.
Recently, The Kroger Company’s Indianapolis bakery identified the use of compressed air in a blow-off and conveyor gap transfer as a major source of energy loss and cost waste. According to the U.S. Department of Energy, “inappropriate use” of compressed air like blow-off produces high pressure atmosphere bleed leading to significant energy loss and unnecessary operational costs. Carrying a 10-15% efficiency return (according to the Department of Energy), compressed air applications can often be achieved more effectively, efficiently and less expensively with alternative solutions using a high flow rate and moderate pressure.
A leading soft drink bottling manufacturer’s compressed air needs were threatening to exceed its Michigan plant’s compressed air capacity. Faced with the cost of buying a new compressor, the soft drink bottling manufacturer re-assessed their compressed air use to identify compressor and energy savings opportunities. In the audit, the soft drink bottling manufacturer identified the use of compressed air in a gap transfer as a source of compressed air and energy inefficiency.
The snack food facility is running with two normally separated compressed air production systems: the main plant system and the nitrogen system.
