1- Recovery of cleaning product in 50mm x 70m piping
A short video showing the passage of the projectile through a detergent dosing line. This method allows for the recovery of residual product within the line, avoiding mixing it and thus getting it unusable, if not removed before the line cleaning phase, between one production cycle and the next.
2- Cleaning pipeline (diameter 130mm) for Powdered Milk
In this video, a pipe approximately 90m long and 130mm in diameter was cleaned, connecting the external milk powder tank to the dosing machines inside the building.
The problem was powdered milk buildup on the inside walls of the pipe, especially in the bends. The projectile, in addition to removing the product residue, also removed much of the buildup with the first shot.
In this case, the projectile was shot using a flange directly connected to the pipe to maximize airflow, allowing the projectile to travel the entire pipe in just 5 seconds. As you can see, the projectile also passed through ball valves, Y-pieces, 90° bends, etc…
3- Product recovery in a pipeline (200m) of Barolo wine
In this video, we see a product recovery and cleaning operation on a 200-meter-long transfer pipe in a winery. Normally, the pipe is emptied and flushed with water, resulting in the waste of a huge amount of product (Barolo wine in this case), which, due to its dilution, cannot be fully recovered.
Our projectile was inserted at the beginning of the pipe and pushed with the same water already used for flushing. As it traveled along the line, it pushed all the remaining wine from the pipe into the silo, thus recovering approximately 600 liters of product that would normally be largely wasted.
The projectile's arrival at the butterfly valve signaled the line's emptying, and as soon as it reached the valve, the operator closed the silo inlet valve, allowing the water to escape through a relief valve. You can see how the escaping water changes from red to neutral in a matter of seconds, demonstrating how little product waste was involved.
4- Cleaning food-grade piping for wine and fruit juices
A demonstration of how simple it is to clean and sanitize food transport pipes. The projectile, propelled by water already used for normal cleaning operations, can be used alone or as a means of propulsion for the sanitizing detergent, thus combining the action of the liquid product with the mechanical force of the projectile, resulting in even more effective residue removal. The constant water pressure prevents pressure drops and also allows the projectile's speed to be regulated by varying the opening of the flow control valve, making it very easy to control the projectile's passage through the pipes.
The second part of the video shows a test in which the projectile was shot into a stainless steel drinking water pipe with a cross-section of approximately 100mm, located at an elevated point, measuring no less than a hundred meters in length, demonstrating how the system can be used even on extensive pipelines, and not just on individual sections of flexible hose.
5- Cleaning the dosing tube for cosmetic foundation
A cleaning test of a flexible hose for transporting cosmetic products, specifically foundation. The new, clean tube was deliberately contaminated with foundation. The product, which has a greasy, oily consistency, is difficult to remove. The combined action of our dry and detergent-soaked projectiles removes the entire residue in just a few steps.
The use of our technology allows for significant savings in detergent and prevents contamination between two different products when the first one finishes dispensing and the second begins.
6- Product recovery and pipe cleaning for cement mortar
This video shows the cleaning of a liquid technical mortar conveying system. The line is 135mm wide and approximately 100 meters long. After the projectile is shot, the product, still fit for sale, can be seen leaking out from the pipe.
A traditional wash with water or another liquid product would have been wasted. In addition to the residual product, the projectile also removed encrustations of old mortar left inside the pipe from previous production cycles, which was solidifying on the inside walls of the pipe.
It is important to completely remove the old product residue, which, if left to age within the system, can lead to the formation of bacterial loads.
7- Food piping cleaning
In this example, we can see the cleaning of a 50m dosing line for canned meat.
A first projectile was shot into pipes that had already been routinely flushed with water, but a significant amount of organic residue was still present. This was removed by the mechanical action of the projectile, reducing and/or eliminating the bacterial load.
The second projectile was then fired and emerged clean, demonstrating that no residue remained inside after the first was fired.
