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.
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.
