Removing Debris from Jars Prior To Filling

These PET jars needed a way to remove static dust prior to filling with product

Back in the spring of this year I had some interaction with a customer in India about a Vortex Tube application.  At the time, they were facing an overheating condition and needed some guidance as to which model would provide the best solution.

Fast forward to this week and this same customer reached out to me again, this time for a static problem.  The application in question was plagued with difficulty in removing small dust particles from the inside of PET jars (shown above).  The jars range from 220-260mm in height (8.6”-10.25”), 80-100mm (3.1”-4”) in diameter, and travel through the process at a speed of ~40 units per minute.

Due to static charge, the dust in this application would adhere to the inside of the jars, presenting a problem with filling during the next stage of the process.  What this customer needed was a way to remove the static, blow away the dust, and then pull a slight vacuum on the jars as a safeguard against any remaining dust.

The solution was to use the Stay Set Ion Air Jet to blow into the jars, removing the static and blowing away the dust, followed by a Super Air Amplifier to remove any dust particles which were not removed by the Ion Air Jet.

The customer was happy with this solution, but there was a bit of hesitation as to whether the Air Amplifier would be able to truly remove debris from the jars.  In an effort to visualize the effects of an Air Amplifier on this type of application I made the short video below.

This video shows paper pieces inside of a cylinder of comparable height to the jars in this application.  After the paper is placed in the cylinder the model 120021 Super Air Amplifier is used to pull the paper out of the cylinder, mimicking the effect it will have on residual dust in the customer’s application.  After seeing the video the customer was confident in the application solution.

Providing this type of assistance for our customers is nothing new for us at EXAIR.  We’re available via phone, online chat, or email for all of our customers, and commit to taking the time needed to really provide the assistance needed.  If you find yourself in need of solid engineering support for an application in your facility, contact an EXAIR Application Engineer.

Peanut Butter And The Flat Nozzle

So, the call came in about mid-morning – an operator at a facility that fills plastic jars with peanut butter needed help with an application…

And I almost got stuck thinking about peanut butter. I like food, and peanut butter is near the top of my list. I’ve seen it successfully applied to cheeseburgers, and the peanut butter & bacon sandwich is even a breakfast staple in some of the Boy Scout groups I’ve been involved with. Crunchy or creamy, peanut butter rules.

Never underestimate the power of peanut butter...or bacon...to improve the quality of any sandwich.
Never underestimate the power of peanut butter…or bacon…to improve the quality of any sandwich. And together, they’re unbeatable. Just don’t ask your cardiologist.

Now, I’m a pro, so I didn’t allow this digression to supplant the attention I was giving the caller. The application was simple enough: the nozzle feeding the jars retains a small amount of the product at the tip, which drips off when it’s good & ready, thank you very much. This is oftentimes when the jar is in motion, so this little glob falls right onto the rim of the jar, causing issues with the protective seal, and a continuing mess as this jar with peanut butter on the outside of it travels down the line.

I recommended a Model 1126SSW 316SS 1” Flat Super Air Nozzle, with Swivel Fitting. They can install this to blow precisely where the air flow can direct the last bit of peanut butter from the fill nozzle into the jar, eliminating the mess, and any chance of a faulty lid seal.

The Model 1126/1126SS 1″ Flat Super Air Nozzle is ideal for high velocity, forceful blow off applications
