From Field to Market: How EXAIR Helps Streamline Vegetable Processing

Published on by John BallLeave a comment

Homonyms are words that are pronounced and spelled the same but have different meanings.  In this blog, I will cover the word lettuce.  One meaning is the leafy vegetable and the other is money.  And I like to save both.  I have an agriculture application that I would like to share where EXAIR was able to supply different products to help save lettuce. 

PowerStream Liquid Nozzle

When vegetables come from the field, they need to be cleaned and packaged for delivery to grocery stores.  The first thing that they need to do is to wash the leaves to remove dirt, compost, and bugs.  They had drilled pipes to spray water onto the leaves, using a lot of water. They were looking to do it more economically. The vegetable packing house purchased the EXAIR PowerStream Liquid Nozzles, model DL8075SS, to do the washing.  These stainless steel nozzles were mounted on a manifold to spray water onto the lettuce leaves.  With the PowerStream nozzles, we can break the water into smaller droplet sizes to increase coverage and reduce water requirements.  Thus, saving money.

The next step would be to dry the lettuce.  They were using a blower-powered air knife, but they could not remove all the insects as it was not powerful enough.  Also, by blowing hotter air which was created by the blower, lettuce would start to brown much quicker.  To improve, they purchased a model 110036SS Stainless Steel Super Air Knife.  The Super Air Knife is an efficient, powerful way to blow compressed air.  With a 40:1 amplification ratio, it will draw in 40-parts of ambient air to 1-part compressed air.  From our Super Air Knife, we blow ambient temperature air, add mass to give a much higher force to remove the water and the insects, and save on compressed air consumption. 

To reduce spoilage, you must have the proper equipment.  For this company, they were able to improve their process to increase production.  And by utilizing less water and less compressed air, they were able to increase profit.  If you would like to improve your processes in packing houses, EXAIR has a variety of products that can help you.  You can contact an Application Engineer to discuss.  For the company above, more lettuce out the door meant more lettuce in their pockets.

Compressed Air Use in the Agriculture Industry

Published on by Russ BowmanLeave a comment

The history of agriculture is really the history of civilization. Once our ancestors moved from hunting & gathering to herding & planting, the concepts of villages and trade took off, and here we are, living in the suburbs, exchanging currency for goods at the local supermarket. The methods in which these goods (the food we eat) are processed have evolved from everything being done by hand, to the use of an impressive degree of modern technology. Some of that technology involves compressed air – hence the subject of this blog. Consider:

  • Gasoline or diesel driven air compressors can power tools and pumps in areas where electricity isn’t available.
  • Fertilizers and pesticides are oftentimes sprayed onto crops using products like EXAIR Air Atomizing Spray Nozzles, which generate an even, controllable spray pattern & flow rate, while making extremely small droplet sizes for maximum coverage.
  • Air Operated Conveyors like EXAIR Line Vacs are widely used to move grain, soil, fertilizer, etc., quickly & easily from storage bins or hoppers.
As a coffee lover, there’s not much I enjoy more than specifying a Line Vac for use with coffee, like the one above being used to convey green coffee beans. They’re used for roasted and ground beans too!
  • Blowoff products like EXAIR Super Air Knives are ideal for cleaning and drying produce carried on conveyor belts.

I had the pleasure of assisting a caller with the selection of a wet-dry vacuum for cleanup operations on a dairy farm. Since it was going to be used in an area subject to liquid spills, they wanted a non-electric solution to eliminate shock hazards from dragging an extension cord across a wet floor. They needed a HEPA filter for silica dust, and wanted the ability to quickly change operation from vacuuming up that dust, to cleaning up liquid (like fresh milk) spills.

EXAIR Model 6303 Premium HEPA EasySwitch Wet-Dry Vac System fit the bill perfectly for them. It’s compressed air operated (so no shock hazard), with more than enough vacuum power for wet or dry cleanup, and the ability to easily switch (as advertised) from wet to dry operation. Also, with no moving parts to wear out, it’ll run darn near indefinitely, maintenance free, when supplied with clean compressed air.

For critical dust containment, the HEPA EasySwitch Wet-Dry Vac System is your durable, reliable, compressed air operated solution!

If you would like to read more about the kinds of applications in which our products help customers solve interesting application problems, please visit our Application Database under “Resources” on the website – (registration required, but it’s free & fast). This resource has details of the successful use of EXAIR products across dozens of industries – Agriculture included. In fact, it’s near the top of the list (to be fair, it’s alphabetical). If you’d like to find out more about how EXAIR Intelligent Compressed Air Products can be used to your benefit, give me a call.

Compressed Air Use In The Agriculture Industry

Published on by Russ BowmanLeave a comment

I didn’t grow up ON a farm, but more than a few of the kids I went to school with did. My wife’s grandpa had a farm, and one of her uncles still does. Farmers have always been the most diversely talented people I’ve ever known. They’re well versed in soil chemistry and plant biology. They have a keen understanding of climate & weather patterns which allows them to sow seed after the last frost in early spring, and gather their last harvest before the first frost of mid-to-late autumn. Most of them are also expert mechanics, welders, and plumbers as well, to avoid costly repair bills on equipment they operate in fairly harsh conditions. And the ones that raised livestock, I’d stack their veterinary knowledge & skills up against just about any vet’s office.

In my twelve years with EXAIR, I’ve had the pleasure of talking with many farmers & other folks in agricultural-type jobs, and a lot of the stuff they use our products for is downright fascinating. Here are two prime examples – one from an agricultural product provider, and one from an actual agricultural job:

*A company that makes irrigation drain pipe uses Model 2485 5″ Standard Air Wipe Kits to cool and dry their extruded 4″ pipe before cutting to length & packaging it for shipment. This replaced a blower operated setup that didn’t completely dry the corrugated outside diameter. The Air Wipe not only blew off almost all the water, all the time, but also allowed them to increase production speed by nearly 10%.

The turbulent air flow from the blower system (left) really just beats on the extruded surface, while the laminar flow of the EXAIR Super Air Wipe (right) strips & sweeps the surface clean & dry.

*Once fruit & vegetables are harvested, most of them go through some sort of cleaning process. EXAIR Super Air Knives are commonly used in conjunction with those processes. Sometimes they’re blowing loose dirt from, say, onions or potatoes, so they don’t turn the wash water into a mud bath. They’re also used to blow the wash & rinse water off, so they’re as dry as possible before packaging or processing. One particular customer uses Super Air Knives for the latter. By replacing blowers with a Model 110236SS 36″ Stainless Steel Super Air Knife Kit to dry freshly washed potatoes, they were able to increase the speed of conveyance…the laminar flow from the engineered Air Knife was better at blowing off the potatoes than the turbulent flow from the blower. Also, since the temperature of the Air Knife’s flow is the same as ambient temperature (because they entrain air from their surrounding at a rate of 40:1 to their compressed air consumption), this extended the time before spoilage. The warmer air from the blower (caused by friction in the rotating elements) was fostering the bacterial growth that leads to spoilage.

Increased potato production + longer shelf life = win/win.

Engineered compressed air products are widely used in agriculture (and, of course, many other industries) for their simplicity, durability, and reliability. If you’d like to find out how EXAIR products can make your life (or at least your job) easier, give me a call.
