Industrial Utility Efficiency    


In open end pipe line suspension flow, or dilute phase pneumatic conveying, proper particle velocity is critical to continuing productivity and product quality. Until recently, measurement of actual particle velocity within the pipe has not been practical outside the laboratory. The plant operating personnel depend on a much less accurate metric - estimating the conveying air velocity in the pipe and relating that to particle velocity.
Pneumatic conveying systems are widely used in manufacturing plants and process industries. They provide a practical method of bulk-solid material transport. A surprisingly wide variety of powders and granular material can be effectively moved from one location to another within the plant. “Compared with other bulk-solid transport systems, a properly designed pneumatic conveying system affords many advantages".
The 2016 Powder & Bulk Solids Conference & Exhibition was held May 3-5 at the Donald E. Stephens Convention Center at Rosemont, Illinois. Sponsored by the Process Equipment Manufacturers’ Association (PEMA®) and produced by UBM Canon, this event celebrated its’ 40th anniversary as the leading event for the powder industry. Whether for dilute or dense phase pneumatic conveying systems, vacuum, blower and compressed air technologies play an important role in this industry.
Formaldehyde is an organic compound that can adopt several different forms. It can be used in solution form as formalin, as a free gas, or in a solid form as paraformaldehyde prills. Formaldehyde is highly toxic to humans, regardless of the method of intake. At room temperature it is a colorless gas characterized by a pungent odor. Even with very short-term exposure, formaldehyde will cause irritation to the eyes including pain, redness, blurred vision followed by sneezing, soreness, coughing, shortness of breath, headaches and nausea. Exposure to elevated levels can lead to accumulation of fluid in the lungs (pulmonary edema).
It’s one thing to move materials during the production process, but when it’s a finished product on the packaging line, choosing the right material handling system is essential. Getting it wrong results in squandered production time when product loss occurs, and wasted raw materials.
Nutriom sets the bar high when it comes to producing its premium quality natural powdered egg products Ova Easy® and Egg Crystals®, that are sold at outdoor retailers such as REI, and online merchants such as; so, when the screw conveyor in their FSIS USDA facility required regular unexpected attention, Leonardo Etcheto, Plant Manager at the Lacey, WA facility knew it was time to look for a better solution.
The plant air system consists of eight, single-stage, lubricated, Sullair rotary screw compressors. All units are in good working order.  Units 2, 3, 4 and 7 are water-cooled and units 6, 8, 9, 10 and 11 are air-cooled. The main plant air system has two primary compressed air dryers, a Thompson Gordon model TG 2000 refrigerated dryer, and a Sullair model SAR 1350 heatless desiccant dryer.  Both units are working according to their design. The TG 2000 uses approximately 11.2 kW and is a non-cycling type unit, and the SAR 1350 uses approximately 200 cfm of purge air to regenerate the wet tower.
