Danish-based company Daniit A\/S has now developed a feeding system for land-based RAS systems which is capable of handling fish feed pellets without crushing them.<\/h2>\n

One of the well-known challenges in the aquaculture business is to avoid fish feed pellets getting crushed through transportation and feeding. Due to the mechanical design, some traditional feeding systems are not capable of handling fragile fish feed pellets<\/a>, which are easily crushed, in a sufficiently gentle way. This issue causes several problems, including higher feed consumption, higher load on the water cleaning system, increased power consumption, increased production of sludge, and others \u2013 all of which significantly increase production costs.<\/p>\n

Danish-based company Daniit A\/S<\/a> has now developed a feeding system for land-based RAS systems which is capable of handling fish feed pellets without crushing them. The system has been developed in conjunction with another Danish company, which is one of the largest producers of traditional feeding systems for the agriculture business.<\/p>\n

Successful trials<\/h3>\n

Daniit has recently (Q4\/2020) installed and commissioned the new fully-automatic feeding system in one of the largest RAS facilities for salmon production, located in northern Denmark. The feeding system automatically handles the dosing and transportation of pellets to 48 dosing augers, corresponding to over three tons of feed per day.<\/p>\n

Trials with pellets ranging between 2.5mm to 10mm in size have proven that fines are reduced to <0.4%. Compared to traditional feeding systems, which generate 5-6% in fines, this is a significant reduction. Test runs with pellets up to 13mm are ongoing, with positive results achieved so far.<\/p>\n

The feeding system handles automatic dosing from one silo, as well as combining dosing from several silos if mixing more pellet sizes is required. Dosing the correct amount of feed is secured by means of high accuracy weigh scales. Compared to other feeding systems which only use volumetric dosing, overdosing is eliminated, which reduces the costs.<\/p>\n

One of the significant key features of the Daniit feeding system software is that the operator can freely choose between different ways of allowing the system to calculate the amount of feed to be dosed in each fish tank per day. This includes:<\/p>\n
