If it is something that we can test ourselves, we’re more than happy to. We recently have taken several requests from customers in the coffee industry, all looking for a similar solution: conveying raw coffee beans. While we were confident in the ability of the Line Vac to transfer those beans, it wasn’t a material that we had ever actually tested here in our shop. A quick trip down the road to a local coffee roaster, and we had some raw coffee beans that we could use for a quick conveyance test. Check out the video below of my colleague John Ball and I conducting a test with our Model 6084 2” Line Vac:

If you’re looking to convey bulk materials using the Line Vac, but have reservations regarding the performance, you can also send a sample of your material in for testing here at EXAIR. We’ll be happy to put the conditions of your application to the test and share the results with you. If you’ve been manually transferring bulk material and are looking for a safer, reliable, and efficient solution the Line Vac is the right tool for the job. With a variety of sizes and materials all available from stock, we’re able to address countless applications and achieve a wide variety of conveyance rates.

The conveyance rate of the Line Vac is easily adjusted. By regulating the input pressure supplied to the Line Vac, not only can you reduce the necessary compressed air demand but you can also control the amount of material flow. Higher pressures will move material, while lower pressures will reduce compressed air consumption. If you need help determining which size and material is most suitable for your application don’t hesitate to get in touch with an EXAIR Application Engineer today. Stop having your operators climbing up and down that ladder to dump material!

Sanitary Flange Air Conveyor Doubles Output for Coffee Bean Roaster

coffee-1149983_1920

For me there’s nothing better than a hot, fresh cup of coffee first thing in the morning. Particularly during the colder mornings like we’ve had as of late, but even in the summer sitting out on the porch sipping on a cup while the sun comes up is a great way to start the day. Just typing this first paragraph has me making my way to the break room for a cup!

We’ve talked about the life of a coffee bean and the processes that it must go through from the fields as a bean all the way through the roasting, grinding, and packaging process. At just about every stage in the production of coffee, EXAIR has a way to help. Just like craft breweries that have taken the world by storm, small-batch coffee companies are beginning to see a similar boom in their business as the market shifts away from large corporate entities and supports small or locally owned businesses.

I recently had the pleasure of speaking with one of these “craft” coffee producers. They’ve been in business for a little while, but as of late have really seen an increase in their sales. To increase production, they invested in a second roasting machine at a substantial capital investment. They’re a small company with less than 10 employees from the front-end to the back-end. While initially they thought all that was needed was to buy a second roaster, they quickly found out that they weren’t getting double the output like they had thought. The problem was that the time spent moving the bulk bags of raw beans into the hopper of the roaster was too time consuming for one person to feasibly handle. They either needed to hire a second person (another substantial investment), or they needed to find a better way of transporting the beans.

After searching online, they came across the EXAIR Line Vac. EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer. Available with smooth, NPT threads, and sanitary flange connections, it allows you to convert ordinary pipe or hose into a powerful conveying system for parts, scrap, trim, and other bulk materials. Available in a variety of different sizes and materials, we can achieve wide range of conveyance rates.

In this particular application, food grade materials were necessary. EXAIR’s model 161200-316 2” Sanitary Flange Line Vac allowed them to maintain a clean environment while keeping it easy to remove and clean when necessary. With the Line Vac in place, they were able to double their output as they’d desired when purchasing the new machine without having to hire another operator. A much easier, cheaper, and cost-effective solution. That Line Vac isn’t going to ask for a raise, request time off for summer vacation, or wander into the break-room to make itself a cup of coffee 😊.

If you have an application where you’re manually transferring bulk materials, give us a call. An Application Engineer will be happy to help evaluate your process and recommend a solution that’ll save you time, energy, and money!
