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!

316 Stainless Steel Products- Always in Stock

Metallurgically speaking, stainless steel is a steel alloy with the highest percentage contents of iron, chromium and nickel, with a minimum of 10.5% chromium content by mass, and a maximum of 1.2% of carbon by mass.

Stainless steels are widely regarded for the corrosion resistance that they exhibit. As the chromium content is raised, the corrosion resistance increases as well. The addition of molybdenum also increases the corrosion resistance to reducing acids and against pitting attacks in chloride solutions. By varying the chromium and molybdenum content, different grades of stainless steel are produced with each suited for varying environments. Due to the resistance to corrosion and staining, stainless steel is ideal material for many applications, especially in the food, pharmaceutical, and chemical industries.

The 300 series stainless steels are considered chromium-nickel alloys and is the largest group and most commonly used. Of the different compositions within the 300 series family, Type 304 stainless is the most widely used followed by Type 316, which has 2% molybdenum added to provide greater resistance to acids and to localized corrosion caused by chloride ions.

Table below shows the nominal composition by mass content for 316 stainless steel

Because 316 stainless steel provides a high level of corrosion resistance, resists pitting, and has good strength properties, EXAIR manufactures many of its products from 316 stainless steel material so that they can be used in the harshest of environments.

Of the EXAIR products these are available off the shelf in 316 stainless steel- Super Air Knife, certain sizes of Adjustable Air Amplifiers, numerous Air Nozzles, Line Vacs including the Sanitary Flanged style, NEMA Type 4X and Hazardous Location Cabinet Coolers. If you need one of our other products such as the Super Air Wipes or Vortex Tubes made in 316 stainless steel, just let us know. Of course we also have them made from Type 303 stainless steel, in stock and ready for shipment (and aluminum, too!)

Custom Air Amplifiers for Special Applications from EXAIR

The EXAIR Super Air Amplifiers and Adjustable Air Amplifiers are used in 100’s if not 1000’s of applications and locations across the world.  For cooling, drying, and cleaning of parts as well as venting and exhausting of smokes and fumes, or dust collection – the Air Amplifiers are sure to get the job done.

The Super Air Amplifiers are made of aluminum and are sized from 3/4″ to 8″ to cover a wide range of applications. Compact and lightweight, no electricity, no moving parts, and instant on/off are just a few of the features.

The Adjustable Air Amplifiers are made of aluminum or type 303 stainless steel and are sized from 3/4″ to 4″, and with adjustable output, provide a wide spectrum of performance.  They have the same great features of the Super Air Amplifier with the added benefit of varying force and flow.

Even with the wide variety of types, sizes, and materials of construction, a customer may have a special need and there are numerous ways that EXAIR can customize the Air Amplifiers.  I’ll touch on several from the basics to the most complex.

  • The Super Air Amplifiers come with a stock shim that sets the performance seen in the catalog. There are other shim thicknesses available if more or less flow is preferred, and they can be installed at the factory if desired.
  • The Adjustable Air Amplifiers are designed for varying output by turning the plug further in to or out of the body. If there is a performance setting that is preferred, we can test, adjust and set it to meet that performance, allowing to be installed and ready for optimum results.
  • If the use of a special material will increase the benefit of the Air Amplifier, we can explore several options with you. One customer needed an Adjustable Air Amplifier with a PTFE plug to help draw a sticky material through a process and prevent the material from adhering to the surface of the Air Amplifier.
  • For those applications where the Air Amplifier is to be installed into a piping system, custom design with flanged ends can be done. Recent designs include stainless steel Adjustable Air Amplifiers with class 150 raised face flanges, and another with sanitary Tri-Clamp style.

  • A special High Temperature version was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. This special design is rated for environments up to 700°F and its surface is protected from heat stress by a mil-spec coating process.  This special High Temperature Air Air Amplifier was so popular, it became a standard offering and is in stock!
