How do automated tank cleaning nozzles work?

Automated rotary impingement tank cleaning devices use patented technology that combine pressure and flow to create high impact cleaning jets. Cleaning occurs not just where the concentrated stream impacts the surface, but also through the tangential force that radiates from that point and blasts contaminants from the surface, scouring the tank interior. The high-impact cleaning jets are delivered in a precise, repeatable and reliable, 360° pattern. This combination of impact in a controlled indexing pattern results in an economic ideal, because impact is a one time investment; chemicals, temperature and time are continual, never-ending expenditures. With a quick return-on-investment, our tank cleaning nozzles are guaranteed to positively impact the ultimate scorecard, your bottom line.

Customers that convert to Gamajet or Toftejorg tank cleaning nozzles from manual cleaning, static spray balls and the fill and drain method, typically realize a

  • 100% Satisfaction with Cleaning Effectiveness
  • 70-80% Decrease in Wash Fluid (Water and Cleaning Chemicals)
  • 75-85% Decrease in Time Spent Cleaning
  • 10-20% Increase in Productivity
  • 90-100% Decrease in Confined Space Entry for Manual Tank Cleaning

Case study: Clean totes in 4 – 8 minutes

TOTES AND intermediate bulk containers (IBCs) are used pervasively in processing

Intermediate bulk containers (IBCs), also known as totes, are used in every processing industry and require regular cleaning.

Intermediate bulk containers (IBCs), also known as totes, are used in every processing industry and require regular cleaning.

and manufacturing applications . They are convenient and cost-effective solutions for materials storage, handling and transport.

One U.S. chemical company uses and recycles totes in its shipping and receiving applications. Totes are used to ship the company’s products, including surfactants and other chemical compounds for the textile industry, and then cleaned for re-use after the shipment has been delivered. Many raw materials are received from suppliers in totes, which are also cleaned for re-use.

Reused totes must be 100% clean to avoid the dangers and expense of cross-contamination. Cross-contamination is caused when one batch contaminates the next batch, leading to inferior quality products, material spoilage and waste.

For years, the company’s operations director was frustrated by the high cost of sending dirty totes to their tote supplier for refurbishing and cleaning. The alternative, having them cleaned in-house by hand, was even less desirable. Manual cleaning is slower and produces unpredictable results in terms of cleaning quality and effectiveness.

Though the issue was not urgent, the chemical company acquired a Gamajet tank cleaning machine as a result of a business acquisition. The cleaning system was trialed to determine if an economic case could be made for using it rather than sending the totes to the supplier for refurbishment. For the trial to be successful, the machine would have to reduce the time spent cleaning totes in-house, and increase the level of in-house cleaning effectiveness.

The system exceeded all expectations and the trial was a resounding success. Gamajet

systems utilize rotary im-pingement technology to create full-coverage, high-impact cleaning. Because of the high level of impact, they use less water and cleaning chemicals as they scour tank and tote interiors. A repeatable and reliable 360-degree clean-ing pattern ensures the tote is perfectly and completely cleaned, including the top and corners. With its use of mechanical force, the Gamajet takes far less time to clean a tote than methods such as manual scrubbing.

Not only did the automated cleaning system deliver the necessary speed and effectiveness, but it accomplished the goals so well that a second Gamajet was purchased. That purchase paid for itself in just one week.

The chemical company now manages its entire tote cleaning process in-house, saving time and completely eliminating the costs of sending totes out for refurbishing. The cleanings are 25–50% faster with the Gamajet than they were with manual cleaning, and a thorough cleaning is achieved in just 4–8 minutes depending on the amount and type of residue. Most importantly, cross-contamina-tion is no longer a concern, and the company is able to deliver reliable product quality and throughput.

How to clean tanker trucks

For many years, the standard cleaning method for tanker washes has involved the insertion of vertically-placed tank spinners through the center manways of trailers. While this method is common and widely accepted, rarely are the ends and bulkhead areas sufficiently clean enough to prevent cross-contamination.

Fortunately, we have created a customer-driven solution for cleaning the typically sidewinder_frontv5difficult-to-reach bulkheads of any type or size OTR tankers: The Sidewinder. The Alfa Laval Gamajet Sidewinder is a revolutionary, affordable accessory for achieving the most effective and efficient tanker, trailer, and railcar cleaning. Enabling a tank cleaning device to be placed on its side, it completely changes the nature of the nozzles’ orbit. Instead of creating an ellipse pattern across the tank wall, the Sidewinder enables the machine to form a figure-8 pattern sweeping the length of the tanker, increasing the number of hits to the bulkhead by 30 times, and cleaning the tanker in half the time.

Coupled with an Alfa Laval Gamajet 8 or Gamajet 4, which are designed to easily handle 20’-30’ throw lengths, the Sidewinder enables your wash station to provide the most efficient and effective clean to every inch of the trailer.

Benefits of the Going Horizontal with the Sidewinder:

  • Delivers 30 times more hits to bulkheads
  • Cleans tankers in half the time
  • Self-balancing capability to maintain revolution control
  • Compatibility with facility’s existing pressures and flows
  • No shadow areas after cleaning

Efficiency gains through high impact tank cleaning

How can I optimize my cleaning? This is a question we get often, and for burnt on soil, viscous products, sludge, and dried media we always recommend a rotating jet machine. Customers that convert from other methods such as manual cleaning, rotary wetting, spray balls and fill and drain, can experience up to:

70-80% Decrease in wash fluid use for tank cleaning
75-85% Decrease in time spent tank cleaning
10-20% Increase in productivity (less tank downtime equals more tank production time!)
90-100% Decrease in confined space entry for manual tank cleaning

Here’s a video explaining the technology and why it works so effectively:

For easier to clean residue, going from manual or static spray ball cleaning to cleaning with a rotating spray ball can give the customers an optimization of approximately 30%, at a much lower initial cost. Here’s a video:

Who is Gamajet? Toftejorg? Alfa Laval? How are they related?

Up until 2003, Alfa Laval tank cleaning consisted of spray balls, static and rotating. Insmcbc_tankcleaning_bkgrd 2003, Alfa Laval succeeded in acquiring Toftejorg tank cleaning (Denmark), and entered into a new market within impact tank cleaning. The Toftejorg product line of tank jets originated within the food and pharmaceutical markets and feature a broad variety of machines for many applications, including high purity features no other manufacturer can.

In 2012 Gamajet, Exton, USA, was added to Alfa Laval’s tank cleaning portfolio. Gamajet machines were developed from another angle, focusing on features for  cleaning the toughest residues, oftentimes in the industrial markets, but also in developing smaller machines that can replace spray balls without changing the tank. The Gamajet range includes machines that can fit through as little as a 2 inch sanitary fitting.

Fast forward to 2015 and the complete line of Alfa Laval tank cleaning is the broadest and strongest portfolio of impact cleaning machines for any industrial, food or pharmaceutical application. If you have a tank, we have the optimal unit for it!


Stuck On You: How to Clean Greek Yogurt Residue in Process Tanks

The Gamajet Aseptic 1 cleans Greek yogurt tanks fast and effectively, using less water and in less time than conventional dairy tank cleaning methods.

The rapid rise in the popularity of Greek yogurt is apparent to anyone who has seen the yogurt aisle at the grocery store recently. Showing no signs of slowing down, the USDA recently awarded a contract to supply high-protein Greek-style yogurt in the National School Lunch Program. Whether it’s the perceived health benefits of this type of yogurt or the pleasing thick texture, people are choosing Greek yogurt over regular yogurt in droves.

Both regular and Greek yogurts are made the same way with milk and bacteria cultures. Where they differ is that Greek yogurt is then strained to remove the liquid whey from it. With that, it takes roughly four times the amount of milk to make an equivalent amount of Greek yogurt as for regular yogurt. This straining creates Greek yogurt’s thick texture that people prefer over regular yogurt. There is nearly twice the amount of protein in Greek yogurt as regular yogurt, so there is basically twice the amount of solids in it.

Rumor has it that cleaning tanks with Greek yogurt residue is cumbersome, to say the least. The head of Alfa Laval Tank Equipment, Bob Delaney, discovered this fact when he finished a container of Greek yogurt and left the dirty spoon out for his wife to clean. To make a long story short, she was less than thrilled with the cleaning process. However, this incident inspired Bob to challenge the North American Tank Competency Center, part of the Alfa Laval Group, to find the best way to clean a Greek yogurt tank in a typical manufacturing setting.

The team chose to compare a static spray ball, rotary sprayhead, and a rotary jethead to find out how well they clean Greek yogurt residue from a tank. All three devices are available in 3-A SSI-compliant versions. However, the three machines use differing technologies to clean tanks. Read the rest of the article here:
