Intelligent Compressed Air® Products for Produce and the Growing Season

Super Air Knife drying fruits and vegetables

If you are like me and love to garden we are approaching the time of year that we start seeding our longer maturing plants like tomato and pepper plants. I have made my purchases of seeds, plant packs, soil and plant food. I am ready and excited for the gardening season.

EXAIR has many applications where our products help the agricultural industry. The use of our Air Knives, atomizing spray nozzles and Line Vacs help assit in the growing, cleaning and movement of products.

EXAIR Atomizing Spray Nozzles atomize fluids (most commonly water) in a range of spray patterns for a variety of uses. These nozzles can be used to keep soils moist, environments humid and also for cleaning the harvested products. The Atomizing Spray Nozzles come in a variety of sizes, styles and spray patterns and can be sized specifically for your application.

EXAIR Air Knives can also be used for cleaning where moisture is a concern before products are placed in packaging containers. Our Air Knifes come is many stock sizes and styles. EXAIR Air Knives are a great option replacing noisy blow-offs and show noise and air consumption reductions.

EXAIR Line Vacs have been used to move grains, soil, sand, wood chips and other products saving labor. They are ideal for moving large volumes of material over long distances. The material flow rate is easily controlled by the size of the Line Vac and by the use of a pressure regulator. No moving parts or electricity assures maintenance free operation.

Compressed Air Receiver Tanks On The “Demand” Side

Most any air compressor is going to have a receiver tank…from the “pancake” types that might hold a gallon or so, to the large, multi-tank arrangements that facilitate both cooling and drying of compressed air in major industrial installations.  The primary purpose of these receiver tanks is to maintain proper operation of the compressor itself…they store a pressurized volume of air so that the compressor doesn’t have to run all the time.  Receiver Tanks, however, can also be used to eliminate fluctuations at points of use, especially in facilities where there might be a lot of real estate between the compressor and the compressed air consuming products.

I recently had the pleasure of discussing an Line Vac Air Operated Conveyor application with a caller.  The need was to move wood chips, from inside to outside the plant, into trailers.  The facility has plenty of compressed air to operate the Line Vacs (the application calls for several) but because the point of operation is so far from the header, they’ll need a “stash” (the caller’s words…we call it “intermediate storage” but he’s not wrong) of compressed air to keep the Line Vacs supplied for operation without any dips in performance.

Enter the Model 9500-60 60 Gallon Receiver Tank.  When an application requires an intermittent demand for a high volume of compressed air, the Receiver Tank provides intermediate storage (or a “stash” – that word’s growing on me) to prevent pressure fluctuations and the associated dips in performance.

Model 9500-60 60 Gallon Receiver Tank

The Model 9500-60 has a small footprint for where floor space is at a premium, and meets ASME pressure vessel code specifications. It comes with a drain valve so you can discharge condensate and contaminants.  A check valve (not included) can be installed upstream to maintain the tank at max pressure so it doesn’t ‘back feed’ other upstream uses.

Use of intermediate storage near the point of use is one of our Six Steps To Optimizing Your Compressed Air System.  If you’d like to find out more about getting the most out of your compressed air, give me a call.

Compressed Air in Farming and Agriculture

I used to help my father-in-law around his farm and this city boy had his eyes opened when he realized it was more than shovels, tractors and livestock. Agriculture is vital for human existence and has become far more advanced over the centuries with a continual thirst for efficiency and technology. Agriculture is just like many other industries looking for continued ways to increase yield, improve quality, maximize labor and improve technology.

EXAIR has many products used in the agriculture and food processing industries. The following details a few example by product line how we can influence efficiencies and quality of products:

Super Air Knife drying fruits and vegetables

Super Air Knives:

EXAIRs Super Air Knives are have ben used to help harvest apples and peaches. In this case they use our Super Air Knives to dry and blow off the fruit after the rinsing process just before the waxing process then again after waxing to blow off any remaining debris or moisture from the fruit before being packed.

A processing company using the Super Air Knife to clean a conveying belt equipped with a weighing system. Before the installation of the the Super Air Knife some of the cut vegetables being weighed would stick to the belt. Their solution was to clean the conveyor belt with EXAIR’s Super Air Knife to ensure continuous operation of the weighing and packaging systems.

Super Air Nozzles:

An onion farmer used EXAIR’s Model 1100 Super Air Nozzle to blow loose onion skins from the onions before packaging to improve the aesthetics to the customers.

Line Vacs:

A food packaging company repackages banana peppers from 55 gallon drums to 1 and 5 gallon containers using our Model 6066 3″ Stainless Steel Line Vac.

Using EXAIRs Model 150200 2″ Heavy Duty Line Vacs a feed stock manufacturer conveys various grains and feed stock simultaneously to a mixer which blends the ingredients. This reduced their blend time by 50%.

A grain processor used Model 142200 aluminum threaded Line Vac to convey small amounts of corn meal into a hopper which feeds into their inspection process.

A company producing worm eggs encapsulated in water soluble wax sold to farmers to enhance soil conditions. They eliminated a hand operation using Model 6081 1″ Aluminum Line Vac  to convey the worm eggs from one classifier to another.

EXAIR has several applications using Atomizing Spray nozzles to add moisture in growing environments . Greenhouses use our Atomizing spray nozzles to control humidity in the air and keep their soils moist to maintain optimal growing environments.

There are many other applications using compressed AIR on farms such as filling tires, cleaning equipment, blowing out water lines and more. Technology drives labor savings and improved quality prototypes are being designed and tested to use compressed air using drones to shoot pods filled with seeds, fertilizer and other nutrients into the soil. EXAIR will remain a strong influence in the growth of compressed air products helping to reduce the carbon footprint, enhance efficiencies and improve cost and quality within the agriculture and food processing industries.

If you have an application and you would like to talk please contact me or any of our qualified Application Engineers at 800.903.9247 and we will gladly help with our best recommendations.

Heavy Duty Line Vacs Within a Machining Facility

An overseas automotive company was using six machines that milled, stamped, and punched aluminum parts.  The machining center used two machines for stamping, and the piece of aluminum was 10mm X 10mm.  The second operation used two machines to punch out a 2mm diameter by 40mm rod. The last operation was milling the edges of the surface to a specific dimension.  The curly swarf that was being produced was around 5mm in diameter by 40mm in length.

Currently they had mechanical conveyors that would dump the scrap material into bins.  The operators would move the full bins to a central dumping area for recycling about 20 meters (66 feet) away.  They used shovels to move the scrap from the bins to a larger container.  This part of the operation took time and was ergonomically unsafe with lifting and twisting.   They were making about 300grams per minute, and with a 24-hour operation, that was a lot of material.  They contacted EXAIR to see if we could help them.

To move the aluminum scrap from the machines to the recycle container, they had to travel 20 meters (66 feet) horizontally, and 3 meters (10 feet) vertically above the floor.  For this distance and the size of the aluminum pieces, I recommended the EXAIR model 152200; 2” Heavy Duty Line Vac Kit.  The through opening for the 2” Line Vac was 44mm (1.75”) in order to move the material through.  This Line Vac is made from a hardened steel construction which is very resistant to wear.  It is also designed for higher vacuum levels to convey materials at a faster rate and longer distances.

The Line Vac is operated with only compressed air to generate a Venturi vacuum, and they are very compact and easy-to-use.  The vacuum generator does not have any motors or moving parts to wear, and the inline design makes it simple to attach a hose to the vacuum and exhaust side.  The kit includes a Filter Separator, Regulator and a bracket for cleaning, controlling and mounting.  They did have to add a hopper to each mechanical conveyor to collect the scrap.  Now, the Line Vac is connected to the hopper with a hose, and the scrap material would travel to the recycle container 20 meters (66 feet) away.

               The EXAIR Air Operated Conveyors, or Line Vacs™, are great tools for conveying items in a “scoop and shovel” type of applications.  If your company manually moves a product from point A to point B, you can contact an EXAIR Application Engineer to see if an Air Operated Conveyor could improve your process.  For this overseas customer above, the model 152200 Heavy Duty Line Vac Kit improved their operation and removed the ergonomic hazard for their operators.
