Cleaner pipes improves the profits!

Preventive cleaning of feed pipes is important to prevent blockage of pipes.

Condensation and deposits in feed pipes are well-known challenges to fish farmers. Feeding over time can lead to accumulation of feed dust and feed oils inside hoses and piping systems creating problems. By partially clogging pipes, the air pressure will rise leading the pellet speed to increase. Increased speed can cause breakage of feed and, in worst case, lead to further buildup and blockage of pipes.

Preventive cleaning of feed pipes is important to prevent blockage of pipes, simplify maintenance and reduce downtime at the farm. AKVA group now launches a completely new concept for automatic cleaning of feed pipes.

“The idea was that if one could easily inject a cleaning (or sponge) into the airflow it would be possible to blow this through the feed pipes on a regular bas-is to avoid accumulation and deposits. After many trial and a long series of testing we came up with this solution, “says Jan Inge Tjølsen, head of R&D department at AKVA group’s headquarters in Bryne, Norway.

This system will not only contribute to a more stable operation and simplify maintenance. Preventive cleaning will also have a positive impact on the financial results. Poor cleaning of feed pipes could result in more feed breakage (dust). Let’s say you have an annual production of 5,000 tons, an FCR of 1.2 and 0.5% extra waste of feed due to breakage, this will result in a total loss of 30 tons feed with a direct cost of NOK 300,000 per year. If the price per kilo salmon is NOK 36 we are looking at a possible loss in fish growth of NOK 900.000 (or USD 115.000) per year.

“This example demonstrates well how clogging of feed pipes can impact the overall financial performance of the fish farm. Much can be gained through optimized operations and preventive maintenance. We invest in innovation and we are constantly seeking to solve the challenges that our customers face daily and by that contribute to increased profits through our technology solutions”, concludes Jan Inge Tjølsen.
