The System Assessment
Oil & Gas
SQF is a food safety management company that conducts audits and reports its findings on companies that voluntarily subscribe to its services. Once an audit is performed, SQF releases the data; from this data, other companies can determine who they want to use for packaging and manufacturing. To facilitate the process, SQF has released a guide that provides directives for processes used in manufacturing.
Nestlé Beats the Heat: Innovative Air-to-Water Heat Exchanger Recovers Heat from Air-Cooled Compressors
When the topic of discussion is making ice cream, the first thing that comes to mind isn’t heat, but at Nestlé’s Ice Cream factory in Tulare, California, heat is recovered from air-cooled air compressors to heat process water. “Right out of the gate, everything is pneumatic,” explains Tom Finn, Project Engineer with Nestlé Ice Cream Division. “Air cylinders and air driven motors, the process piping valves which divert, route, stop/start, and mix process fluids, our packaging machinery including rejection, cleaning and vapor removal processes, all of these rely on compressed air.
Compressed air is the most common utility used in a typical industrial facility. It encompasses most operating aspects of the plant. The compressed air system can end up being the most expensive utility due to the focus that if production is running - then leave the system alone. Processes and machines are added and as long as the compressor can handle the increasing load - all is good. This brings us to our subject matter. The plant adds a process, a specialty coating line, requiring respirator protection. The plant determines supplied air respirators are the best choice. They want to be responsible and do the right thing so they start by reviewing what OSHA has to say on the subject.
