Application Database: Compressed Air Use in the Food & Beverage Industry

EXAIR uses many different methods to connect with our customers.  We have our website, social media, blogs, publications etc. We like to share solutions for some of the most common pneumatic problems in the industry.  EXAIR generated a large collection of application information where EXAIR products have already solved problems and improved processes.  We organized them by Application and by Industry.  In this blog, I will show you how to use the Application database; specifically, for the Food and Beverage Industry.

Compressed Air Systems are considered to be a fourth utility within industries because they use a large amount of energy.  Whether an air compressor uses fuel for portable units or electricity, it is important to use this system as efficiently as possible.  This would apply to the Food and Beverage industry.  EXAIR has a library of different processes in which we already improved these areas safely and efficiently.  If you are in the Food and Beverage industry, it would benefit you to take a peek at the implementations where we already improved, establish OSHA safety, and saved money.

Here is how you can find this library.  First, you will have to sign into EXAIR.  Click here: Log In.  Once you fill in the proper information, you can then retrieve a great amount of resources about EXAIR products that we manufacture.   The Application Database is under the Knowledge Base tab.  (Reference photo below).

At the Application Search Library, we have over one thousand application that we reference.  In the left selection pane, we organized then in alphabetical order under two categories, Applications and Industry.   (Reference photo below).

Scroll down in the selection pane until you come to the sub-category: Industry.  Under this Sub-category, you will find three selections that are related to this blog: Food and Beverage, Food Packaging, and Food Processing.  We have other applications that may relate to your process like; Beverage Bottling and Beverage.  You will find many applications that EXAIR has already helped to improve and it is documented.

Why is this important?  If you are a plant manager or owner, the value of the Application Database can improve your current processes with pre-qualified results.  Within the Food and Beverage industry, simple solutions can be found to address those “nagging” issues that you see every day.  For crisis situations and shutdowns, EXAIR categorized these applications in a way to reference quickly and easily.  And since EXAIR has a high volume of stocked quality items, we can get the parts to you very fast; minimizing downtime.

In today’s market, companies are always looking for ways to cut cost, increase productivity, and improve safety.  EXAIR can offer engineered products to do exactly that.  With the “been there and done that” solutions already described in the Application Database; you can have confidence in finding a way in solving pneumatic issues.  If you do not sign up at www.EXAIR.com and take advantage of these offerings, you will be missing out on a great tool in optimizing your compressed air system.

Cleaning A Cookie Cutter Die Using A 24″ 316SS Super Air Knife

I recently worked with a food manufacturer who was looking for a way to clean the die roller in their cookie cutting process.The cutting machine is fed by a ribbon of extruded dough that is cut into various shapes as it passes by a 24″ wide roller. After the cookies are cut, the finished product then travels down a chute to a feed tray where it is conveyed to a packaging area. They were starting to see an increase in rejects as some cookies were being “double stamped” as a result of residual dough sticking to the die. They tried to install a brush traveling the span of the roller in an effort to wipe it clean but this wasn’t very effective and also caused some contamination as some of the bristles would break loose. They then tried having an operator use an air gun to manually clean the roller and while this did work, it severely slowed the process down, reducing production and negatively affecting their bottom line.

That’s a lot of cookie cutters!

After discussing the details of the application, I recommended the customer use our 24″ 316ss Super Air Knife in the application. The Super Air Knife produces a laminar sheet of air across the length of the knife and consumes only 2.9 SCFM per inch of knife length when operated at 80 PSIG. The 316ss construction resists pitting and is the preferred choice when being applied to a food process as it minimizes the potential for metal contamination.

SS Super Air Knife available in lengths from 3″ up to 108″

When it comes to wide area treatment, an Air Knife is the optimal choice. If you have a similar application that requires assistance, please contact an Application Engineer at 1-800-903-9247.

A Super Air Knife Improves Bagel Operations

Did you ever wonder how that deep brown crust is created on pretzels and bagels? There’s just a little more to it than toasting them under a burner.

A process engineer from a well-known bagel company contacted me about a problem in their operation. They were having issues containing the lye solution in a dip tank that the bagels are run through. Lye, also known as sodium hydroxide, is a very corrosive, alkali substance.  When handling this liquid solution,  personnel protection equipment (PPE) is required to protect skin and eyes.  The engineer found evidence of the lye solution dripping from the conveyor onto other components in the process.  For safety, maintenance and cleanliness, he needed to find a way to contain the lye in the dip tank area.

The conveying system used a gear-driven sprocket to move the conveyor. The conveyor was a 30” wide open-mesh belt with chain links attached to the outside for the sprocket.  It was used to move the bagel dough into a dipping station which contained the lye solution.  As you can imagine, there are plenty of areas for the solution to collect into these voids of the belt and drip downstream.  The dough would soak up the solution and then travel into the oven for baking.  As the dough is heated, the lye will start to react with the steam and bagel proteins, turning it into something safe to eat. This Maillard reaction creates the browning of the dough and that yummy crust on the outside.

To keep the process safe and clean, they had to keep the lye solution in the dipping area. Because the concentration of the lye was very low, we recommended a stainless steel Super Air Knife.  (EXAIR offers a variety of materials for different types of chemicals)  The engineer ordered model 110030SS Super Air Knife, mounted it above the conveyor, and aimed it in a counter-flow direction to the conveyor travel.  As the belt exited the solution, the Super Air Knife would blow the excess from the mesh and the links back into the dip tank.  This kept the area clean and safe from the caustic solution.

If you have similar processes with caustic or corrosive chemicals that need to be contained, we would be glad to discuss your application and determine which of our products would be helpful to keep your processes, personnel and facility safe.
