316SS Sanitary Flange Air Operated Conveyors Pull Corn Meal Quality Samples

Agriculture, it’s a word that invokes a lot of imagery. From the vast rolling fields, to animals roaming, to a simple life of tending to the land. For some it is the perfect life of hard work and simple living. Agriculture can make one think of tractors, heavy equipment, silos, fencing, and much more. But there is one thing that does not typically come to mind, and that is compressed air. Even though compressed air is not commonly thought of being used in agriculture does not mean that it cannot be used. In fact, it can be very useful.

In one application a manufacturer of corn meal needed to take a sample of the product to test the moisture content and quality before it was loaded into a rail car. The lab tech use to have to go out to the silo to scoop up about a pint and transport it back to the lab to be tested. To eliminate the manual retrieval and delivery of the corn meal EXAIR recommended a model #163300-316 3″ St. St. Sanitary Flange Line Vac Kit and was sold to the customer. A system of 100ft of pipe was installed from the silo to the lab so that the test sample could be conveyed by the Line Vac directly to the lab to be tested. This simple fix improved the reliability of the sample and decreased the time it takes to grab a sample. Along with the added benefit that now the lab tech does not need to walk over and scoop the sample out of the container or off the ground.

EXAIR’s Family of Sanitary Flange Line Vacs

Line Vacs are a great product for conveying bulk material from point A to point B and excel with “bucket and ladder” type scenarios where personnel is manually loading or unloading batches of material or scrap. EXAIR’s Air Operated Conveyors have always been well suited for applications involving food as the internal components are smooth and can be cleaned out easily and sanitized. With a 316 Stainless Steel body the unit provides superior corrosion resistance and can withstand most caustic cleaners and oxidants. The flange style connection also makes it easy to hook up and remove for cleaning purposes.

Model 161200-316 – 316 Stainless Steel Sanitary Flange Line Vac

Sanitary Flange Line Vacs are all made from 316 Stainless Steel and come in four sizes: 1-1/2”, 2”, 2-1/2”, and 3”.

Compressed Air Uses In Industry

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

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.

Cookie Blowoff Using The Full-Flow Air Knife

A machine manufacturer was working with a food company who was looking to design a blowoff station for their cookie making process. During the production cycle, the cookie dough is put into a former that pushes the dough through round dyes that forms several rows of cookies across a conveyor. As the cookies travel down the conveyor, they are topped with ground peanut bits and sent through a flash freezing process. It was after this process, the company was looking to install the blowoff station to remove any excess peanut bits but were concerned if the air velocity was too high, they may remove too much of the ground peanuts or possibly blow the cookies themselves off of the conveyor. Another area of concern was the amount of space available to install the station was limited, so they were needing something “compact” so they could design the machine to take the least amount of real estate as possible.

The machine designer was somewhat familiar with our Air Knives, but was unsure which design would best fit the customer’s needs so they decided to reach out for assistance. After discussing the particulars, I recommended our 36″ Stainless Steel Full-Flow Air Knife Kit. Of the 3 designs of Air Knife we offer, the Super, Standard and Full-Flow, the Full-Flow Air Knife produces the lowest outlet velocities, it is also our smallest profile offering at only 1.25″ x 1″  for stainless steel construction. The Full-Flow Air Knife provides a laminar flow of air the entire length of the knife and uses a 30:1 amplification rate (entrained air to compressed air) for efficient compressed air usage. By incorporating the pressure regulator included in the kit, they would be able to easily control the exiting air velocity to effectively remove the excess peanut bits without ejecting the cookies from the line.

Full-Flow
The Full-Flow Air Knife is the ideal choice where mounting space is limited. Lengths available up to 36″ in aluminum or stainless steel construction.

For assistance in selecting the best Air Knife to fit your needs or for additional support with another application or EXAIR product, give me a call at 800-903-9247, I’d be happy to help.
