Food Safety - Temperature matters!

Posted on August 15, 2013

The food industry is challenged with bacteria that evolves as fast as the processes to manage them.  Listeria and Salmonella, the 2 big challenges, not to mention E. Coli, are changing and becoming more heat and chemical resistant.

 

 

The result is biofilms that grow quickly and are tougher to eradicate.  The treatment approaches gaining ground are enzyme based chemical that breakdown the biofilm and help expose the bacteria so that the cleaners and sanitizers can work their magic.  The belief is that sanitization is about 95% effective.  It is good that the human intestinal system can deal with that possibility of 5%.

 

The food industry works hard to keep their facilities and systems clean - from the loading dock to the processing equipment.

 

We have learned that the cleaners and sanitizers work best within a temperature range specified by the manufacturers.  Enzymes are most effective between 120°F and 150°F.  The sterilization process typically involves steam at ~~ 250°F.  Sterilization is more costly to perform, although with accurate temperature monitoring to insure saturation, it is the only process that is 100% effective.

 

Thank you to the Food Processors for their diligence and dedication to these important processes and cleaning regiments - we as consumers truly appreciate your efforts...

Autoclave Temperature Measurement

Posted on July 29, 2013

 

The Autoclave processing environment can present an interesting set of challenges.

  • Is the drain measurement representative of the load?
  • Is the load uniformly heated?
  • How many wall penetrations are required to insure proper processing?
  • Large chambers required to sanitize large items create sensor cables routed in may places.

From Autoclave as small as those used in a dental office or hospital, to systems large enough to laminate airplane wings, the challenges present themselves in many ways.  The team at Burns have frequent conversations about the issues as they related to the measurement need with multiple autoclave users.

 

See earlier post about the Autoclave load measurement challenges.

 

Each of these systems present unique challenges including access into the chamber, confined or complex maintenance access, and measurement at the point of highest interest; on the actual item(s) being processed.

 

We have responded to these concerns with several products designed for this exact environment.  The SA series of Autoclave instruments are water tight, durable and built for the demands of multiple Autoclave systems.  See the entire Autoclave family.

RTD Performance - Periodic Verification?

Posted on November 14, 2012

YES!   It can be as easy as measuring the resistance in a container of ice water. (you don't need a Triple Point of Water Cell.)ice-bath-a.JPG We have discovered too many times that sensors are installed in systems that experience a combination of temperature cycling, over temp excursions, vibration, high flow rates and /or just left unattended for years.  In many cases this is not a concern based on the requirements of the measurement.  Although, if these influences exists and the expectation is to be confident that the measurement represents the actual process media temperature, periodic verification can ensure that confidence. tech-papers.jpg This paper titled:  Developing a Periodic Performance Verification Program  for Platinum Resistance Thermometers, will help you understand the importance, and provide some guidance on how to establish a verification approach that is right for your application. Visit the Burns Website Technical Papers page - register/sign-in to access ALL the papers.  This set of papers provides an in-depth study of the source of error,  the cost of measurement error, and how to manage the multiple influences on the measurement. Our Mission is Your Measurement! We believe that any sensor will provide a measurement, although if the influences that exist in the application are not managed or planned for, that measurement may not represent the actual process temperature. If you would like to discuss your application to ensure measurement confidence in your operation - call or send a note.  Here is our contact information.

Burns RTD for Autoclave Applications

Posted on October 4, 2011

We have heard multiple frustration-filled stories about large autoclave systems and damaged sensors as large carts and rack are move in and out of the chamber.  These conversations have pushed the envelope regarding what an RTD looks like to serve this durability need.autoclave-group-1.jpg

 

Known in the large autoclave circles as SAH and SAX, these provide the accuracy necessary and the durability hoped for by Autoclave users.  These Heavy Duty sensors join the previously released Autoclave RTDs, SAC (Sanitary Autoclave Classic) and SAL (Sanitary Autoclave Load).  See all the details in the Series S Autoclave Supplement. (In PDF format)

 

Curious about how Durable?  Intrigued or challenged with a process of your own?  Send a note to info@burnsengineering.com we'd love to hear from you.

Health Dept in KY tightening rules

Posted on February 25, 2011

wdrb_fox41_louisville.jpgInteresting!  Reported by WDRB Fox 41.  The Kentucky Health Department in its new Restaurant Health Standards, has reduced the temperature specification for holding cold food from 45F to 41F.  Food and consumer safety stated as the driving factor.

 

That's only a 4 degree change!  It doesn't seem like much unless your measurement is OFF by a couple degrees and then the risk of food born illness and non-compliance is just an FDA Inspector or sick customer away.  Read the article.picture-5.png

 

We can help with that!

 

With the right Burns RTD and a little coaching about the potential sources of measurement error, 41F can be achieved with confidence!

 

Give us a call, Bill would love to discuss the options and approaches -  952-935-4400, or drop a note via info@burnsengineering.com.

Mercury in Glass - a thing of the past.

Posted on February 16, 2011

nist.jpgRead this important message from NIST:

 

No more Calibration of Mercury Thermometers (MiG).

 

 In the big picture, this is necessary to help build momentum to STOP the use of these devices.  There are a lot of reasons they are in place, but the Mercury risk to the environment is too great.

 

FYI - Burns can help provide an RTD based instrument to replace the MiG.

nistfullbanner2.pngNIST engineers D. Ripple an G. Strouse offer their thoughts on alternatives to Liquid in Glass (LiG) Thermometers.   The abstract refers to the increase in automation and the desire to eliminate mercury as driving a lot of thoughtful consideration as to options.  Originally published in 2005 in the jai_new.jpgJournal of ASTM International, the issues still exists and we hear that there are still a lot of LiG devices still in use.

 

Are you still using LiG devices?   Contact a Burns Temperature Measurement Expert at info@burnsengineering.com.  We'd love to discuss the alternatives to LiG.  Or visit the Burns site, browse around and if you don't see what you had in mind, click the black button "Help me find the right solution".  We'll be in touch shortly.

7.1 degrees, the sweet spot.

Posted on March 25, 2009

In this spring season the Maple trees provide us with a great example of the importance of temperature through the process of producing Maple syrup. 

 

From Ohio State University, the North American Maple Syrup Producers Manual, bulletin # 856 explains the relationship between the sugar concentration and the boiling point of Maple syrup.  The target concentration is 66% which happens to boil at exactly 7.1F above the boiling point of pure water (at the altitude where the process is taking place.)  I didn't realize the precision involved with boiling sap into syrup.

 

Thanks to Bill B. at Burns for discovering this sweet example of how temperature plays a role in product quality, even if the process is taking place in your back yard.  For more info on Maple Syrup, visit this Wikipedia page.

 

As you know, It's all about the temperature!

Air Temperature & only the Air Temperature

Posted on August 28, 2008

The Engineering team at Burns has for many years enjoyed the air temperature measurement challenges in clean rooms, HVAC, storage areas, transportation, compressor rooms, production areas, environmental chambers, critical office areas..... 

averaging-air-temp_1.jpg

In some instances it's all about durability and accuracy.

air-temp-tough.JPG

In other cases the challenge is measuring the temperature of the  AIR and not the WALL or some other influence within the wall.

air-temp-vs-wall-temp.JPG

 

Burns brings to these applications;  a myriad of design styles and adaptations, the wisdom that can be found in the series of technical papers on PRT Sources of Error and a passion for creative problem solving.

 

Share with us your Air temperature measurement challenge and we'll get the team engaged in making you a hero!  Call us at 952-935-4400, email us at info@burnsengineering.com or comment here on the BEblog.

 

We are ready to discover, design and create something to insure your success.  That's just the stuff we like to do....

RTDs in small packages…

Posted on July 11, 2008

The best things come in small packages.  I've heard that phrase many times.  Recently the engineering team at Burns has been working on a stealth project to evaluate material and process approaches for the purpose of; mini, tiny, micro and just little RTD's.  We code named the project SLIM and gave it a mascot....slim.jpg

 

 

 

We discovered some interesting materials and process options, and broke a few assumptions and perceived constraints.  Then, in the design mode, applied these ideas and created a few new RTD's for various applications throughout the BioPharma, Food & Beverage, PetroChem and Ethanol industries.  These little RTD's play a role in Bearing temperature monitoring, product transit condition monitoring and various surface sensing and tight locations where addition temperature profile and awareness is important to the process.

 

slim-2.png

 

The team had a blast think beyond the rules, historical approaches and known materials.  In true "achieve, change and improve" mode, we are doing it again.

More than a FEW at the FEW Expo

Posted on June 17, 2008

Ethanol and it's expansive support industry at the FEW Event have rushed the gates at the Gaylord Opryland Resort and Convention Center.   They are talking everything from filter bag systems, mixers, bacteria issues, biodiesel, fermentation and thermal oxidizers....   The conversation even dipped into the area of CIP (Clean in Place), posing the question, "Should the Ethanol fermentation process move toward the sanitary guidelines similar to the food and beverage industry?"  This was driven by the co-product "Distillers Grain" entering into the food stream through the animal feed.

 

The Expo opened Monday evening, breaking the ice with a Grand Opening and massive social in the expo arena.  The spirit in the room was an interesting mix of excitement, passion and commitment to all the good aspects and value of Ethanol as a clean and renewable fuel energy source.  That doesn't mean that there aren't questions and concerns about the interdependency with the other uses of corn, and the economic complexities as the ethanol industry grows....  It sounds like these folks are aware of all of this, and are committed to being good stewards of the resources they consume and at the same time looking for additional Sugar & starch sources to balance the demand for corn.  One alternate fermentation product being discussed is ALGAE!  Now that's being creative!

 

More later from on the Fuel Ethanol Workshop & Expo and the passionate folks in attendance.

Committed to your success! MWFPA 2007

Posted on November 21, 2007

WOW.....

 

I am sitting at the MWFPA 2007 event listening to Vince Lombardi, Jr. speaking about Teamwork!  A topic that transcends industries, businesses, projects and issues.

 

It got me thinking....

 

That is the key to what Burns wants to BE;  A team, with you.  To BE in a Teamwork relationship about the temperature related challenges that you have on your list of concerns.  To bridge our Temperature expertise and your process expertise to achieve the goal which can be best described as your success.

 

For a guy from Minnesota who happens to be a Minnesota Viking fan, I am humbled by the powerful message, in the presence of the son of Coach, Vince Lombardi.

 

His message:  "combining clear goals and dreams, with commitment and mental toughness, will enable success", is exciting and energizing.

 

Burns will BE committed and BE temperature experts on your team.

 

We would love to hear from you about how we can team-up for your success.

Thinking about MWFPA.

Posted on November 21, 2007

How important is the requirement for No-Animal-Derived materials?

 

3A vs. the ASME-BPE? What’s your perspective?

 

Is irradiation effective as a method to insure safety?

 

International expansion: Your thoughts on maintaining food safety?

 

The role of temperature control on your CIP/SIP efforts?

 

Would better temperature-control improve your efficiency?

 

MWFPAWow. Lots of questions on our minds as we head to Milwaukee next week to participate in MWFPA 2007. The food & beverage manufacturing process is a challenging one. We've learned that by being trusted partners for clients in the food & beverage industry for more than 45 years. So we hope to see some old friends and meet some new ones next week.

 

But why wait? Let's start the conversation right here: What are the most pressing issues you face in the food & beverage manufacturing process?

 

Bet we've got a few ideas of how temperature measurement can help!

As you may know, the operating conditions of the autoclave process ranges from vacuum to positive pressure steam at temperatures up to 135C. Individually, these conditions are fairly easy to design around, but the combination presents a few interesting challenges in the RTD world – and sealing the device such that the insulation resistance performance is maintained after multiple cycles is the fun part.

 

Other features we designed into our new autoclave sensor include a .125 diameter stainless steel sharp-tipped sensor sheath to facilitate insertion through the rubber membrane of the load cell, and a dual Pt100 element that can support either a 3- or 4-wire operating connection. The cable features a silicone rubber jacket providing the durability necessary to meet the handling concerns that were shared with us from users of large chamber autoclave systems. We also designed a bulkhead/transition system to assist in providing a sealed penetration through the wall of the autoclave.

 

Now back to the sealing challenge!

 

Inside the transition housing (or handle which is laser marked for easy identification) is an elegant design which protects the 8-wire joints, simply yet effectively seals the sensor and involves very few complex parts. The design insures ease of manufacture and an epoxy fill method that results in an extremely stable final assembly.

We're proud of the creativity of the approach and through our design verification testing, we're confident in the high reliability of the Model 21090 in the harsh environment of the Autoclave processing cycle.
