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.

Air Nozzles and Air Jets: An Overview

One of the simplest solutions to lower your air consumption and noise level when it comes to compressed air is to switch your open tubes or pipes and liquid nozzles which are being used for air applications to an engineered compressed air nozzle. EXAIR’s Engineered Air Nozzles and Jets provide a simple solution for a wide variety blow off and compressed air applications and can solve a multitude of process problems efficiently. These applications can include simple blow offs, cooling, part ejection, and much more.

Super Air Nozzles:
Super Air Nozzles are one of the more versatile of all of EXAIR’s Engineered Air Nozzles. They come in many different sizes from a tiny size of M4 threads and 13 millimeters long to the largest with  1-1/4 NPT threads which has a 2″ hex and is almost 5″ long. These are usually used for standard blow off applications that replace open pipes to reduce your air consumption and noise. The force values vary from 2 ounces to 23 pounds of force. 

Another variation of the Super Air Nozzles is the Flat Super Air Nozzles; these nozzles create a small flat curtain of air at a high force to provide a wider blow off area for smaller NPT sized nozzles. The 1” and 2” Flat Super Air Nozzle also have replaceable shims that allow you to adjust the force coming out of the nozzle by increasing the amount of air that is used.   

EXAIR Air Nozzles

Back Blow Air Nozzles:
Back Blow Air Nozzles are designed in a way that blows that makes it easy to blow out the inside of pipes. The Back Blow Air Nozzles have holes around the outside diameter pointed back that creates a cone of air around the air inlet port. This makes it easy to dislodge clogs in pipes that you don’t want going back into the machine and for blowing out liquid and debris from the inside. They are also commonly used with EXAIR’s Chip Shield as to prevent any particles from flying back and hitting the user. Back Blow Air Nozzles come in three sizes: M4, ¼”, and 1” and can be used on inside diameters ranging from ¼” to 16”.

Super Air Nozzle Clusters:
Super Air Nozzle Clusters use a number of the ¼” Super Air Nozzles to create one nozzle that has a wider cone and larger force. Clusters are usually used in wide area blow off but can also be used for part cooling and part reject as they do supply a wider area of force. Super Air Nozzle Clusters are sized by the number of nozzles in the cluster; the three sizes that we offer are 4-nozzle cluster (3/8” NPT inlet), 7-nozzle cluster (1/2” NPT inlet), and the 12-nozzle cluster (1” NPT inlet).

Air Jets:
Air Jets amplify the total volume of air into a high velocity stream of air. This makes it very useful for blowing off/drying applications and cooling applications due to the higher volume of air flowing through the unit. Air Jets come in two variations which are the High Velocity Air Jet and the Adjustable Air Jets. The High Velocity Air Jet uses a 0.015” shim that allows the air to escape the unit at a high velocity laminar flow to entrain the surrounding ambient air; this can be adjusted down using the shim kit which includes a 0.006” and 0.009” shims. The Adjustable Air Jet allows the user to easily adjust the air gap using the micrometer gap indicator.

Engineered Air Nozzles by EXAIR Replace Modular Coolant Hose & Save Thousands!!

A common item that can be found in a majority of machine shops is the blue or gray knuckle-jointed hose used to dispense coolant on lathes and CNC machines. EXAIR also uses this same hose with our Cold Guns and Adjustable Spot Coolers for applications that cannot or do not wish to use liquid coolant as a means of keeping the heat down on their tooling. Since the cold air discharges at atmospheric pressure, this is an acceptable application.

Another application is using this style of hose as a compressed air blowoff. This is NOT a proper use of the hose and is not only a considerable waste of compressed air but can also pose a safety hazard. Using this method for compressed air blowoff is not compliant with OSHA 1910.242(b).

I was recently contacted by a customer in Indonesia that was using an array of (6) of these knuckle-jointed hoses with a ¼” round nozzle attachment for a blowoff operation. The customer had a series of rubber pads used in the construction of a toy castle. The pads were brought along by an overhead conveyor and a design was printed on the head of the pad.

The nozzles were used to dry the ink before the pad made it to the next part of the process. This was a new product line and the processes involved were being evaluated for potential places to save on compressed air rather than adding overall capacity to their system. After using a variety of EXAIR products for other blowoff applications, they came back for another engineered solution.

HP1126-9280 unassembled

After testing both a 1009-9280 (Adjustable Air Nozzle w/ 30” Stay Set Hose) and an HP1126-9280 (1” High Power Flat Nozzle w/ 30” Stay Set Hose), the customer determined that the airflow pattern from the 1” Flat Nozzle was more conducive to drying the rubber pad and purchased the remaining units to replace their original method. The compressed air savings was noticed immediately!!

For the old operation, they had to regulate the pressure down on the hose to 25 psig so that the hose wouldn’t break apart. (1) This hose , with a ¼” round nozzle, will consume 52 scfm at 25 psig of supply pressure. With (6) of these they were consuming a whopping 312 scfm!! Since the HP1126 is compliant with OSHA directive 1910.242(b) and will not break apart at higher pressures, they were able to operate at 80 psig while only consuming 17.5 scfm. They saved more than enough air for their new process and are evaluating whether or not they can turn off one of their smaller 25 HP compressors.

The new setup with the EXAIR engineered solution was able to save them 207 scfm of compressed air. Assuming a cost of $.25/1000 scfm and a 40 hr work week, this translates to an overall savings of $6,458.40 per year off of their utility bill.

207 scfm x 60 minutes x 8 hrs/day x 5 shifts/week x 52 weeks/year =25,833,600 scf

25,833,600 scf x ($.25/1000 scf) = $6,458.40
