Temperature Mapping in Tray Dryers

Hey guys I am from a pharmaceuticals industry, in many of our industries we are doing temperature mapping in tray dryers for 8 hrs initially and there after for 4 years once in every 3 years, on what basis did we fix this??

Fix what?? Not sure if it's just me or not but I don't understand your post at all.

"we are doing temperature mapping in tray dryers for 8 hrs initially and there after for 4 years once in every 3 years, on what basis did we fix this??" ?????

Please clarify.

Why was this marked off topic after the fact? I asked the O.P. for clarification on his or her post because I truly don't understand what he or she is asking. I do have some knowledge of temperature mapping of ovens, I do it every 3 months on our curing ovens per ISO 16949 requirements. I may be able to help but need to understand what they are asking.

"8 hrs initially and there after for 4 years once in every 3 years" Needs restating.

You might try using a language translator to help you.

These OT markings are AN INSULT!

They must surely be discriminatory and vindictive, because they were not out of line in any way!

Maybe whoever marked them OT would care to explain to those of us too stupid to understand what "for 8 hrs initially and there after for 4 years once in every 3 years, on what basis did we fix this" actually means because I surely don't know!

As I stated earlier, I do temperature profiling (mapping) in all of our cure ovens at work. I use a DataPaq Easy Track 2. This is done in the requirements of ISO 16949 (formally TS-16949).

This is not much more than a preventative measure to insure even heating in the ovens, hot zones, no dead zones, time at temp, etc.. It would tell us if our ovens had a problem and would tell us where to fix it (in the traveling ovens).

My questions to you are, what is the purpose of your mapping? Is it do to a standard such as mine, or was there a problem with the dryer?. Also I need clarification on the timing that you mentioned, I don't understand. What did you fix, or what do you think you need to fix?

Without a definition of the <...we...> and the design records that the <...we...> used to commission the plant, how on earth is the forum supposed to answer (rhetorical question - NNTR)?
