When in the quest for six sigma performance it never hurts to have a little “head room” in the process. In simple terms, this means that the equipment used should not be “maxed out” to achieve the desired result. I’m sure that none of us would be comfortable if we had to keep the accelerator …
“Electropolishing,” (often shortened to E-P) is a term frequently heard in cleaning circles. Electropolishing of surfaces of cleaning equipment is employed to provide enhanced cosmetic appearance and, more importantly, to enhance their functionality. What is Electropolishing? – Electropolishing is a lot like electroplating except in reverse. In electropolishing, metal is removed rather than added as …
I have written before that there are four major variables we consider in cleaning – – Time, Temperature, Chemistry and Agitation. Based on some recent feedback from the field, however, I guess I need to provide a little more emphasis on the benefits and definition of agitation as it relates specifically to ultrasonic cleaning processes. …
In The BIG Four, I talked about the four important variables in cleaning. These are time, temperature, chemistry and agitation. In that blog, I mentioned that a shortcoming in one variable can, to a point, be overcome by changing another of the variables. For example, increasing temperature or changing chemistry may reduce the time required …
In order to achieve six sigma results, one must evaluate, measure and statistically control ALL phases of the cleaning process. A typical cleaning process is comprised of three main stages – – washing, rinsing and drying. Each of these must be addressed and controlled separately as any one of the three being out of control …
A reader has asked about the possibility of using ultrasonics to wash dishes. He writes – – – “Ultrasonic cleaning in a dishwashing application is something that I am currently interested in. Having read some of your other blog posts which mention sequential use of turbulation in the liquid to supplement the ultrasonics, I was …
Just about everyone can recognize the benefits of sterilization to eliminate bio-burden in a plumbing system. Heat or chemicals toxic to living organisms are periodically introduced to kill the offending critters. This process can be conducted using either CIP (Clean In Place) or COP (Clean Out of Place) procedures. CIP simply means cleaning by flushing …
Previous blogs have addressed what might be called the universal or common requirements for sanitary plumbing. Although obviously important, things like selecting the right materials and surface finishes are only the beginning of designing a system which is compliant with the requirements for a sanitary system as they may be defined by a particular user. …
As revealed in the preceding post, the material of construction is a critical factor in the design of “sanitary” plumbing. Although the selection of material is important, there are other considerations that are equally important in the design of a system that will resist contamination. Surface Finish – Surface finish can have a significant influence …
I can think of no term found in specifications for cleaning machines that causes more controversy and confusion than the term “Sanitary Plumbing.” This term, frequently found in specifications for cleaning and processing systems destined for the semiconductor, medical, food processing and a growing number of other markets is vague and means different things to different industries …
