In the aquaculture industry, all dead fish, fish trimmings, and by-products from production must be handled in accordance with regulations.

Dead fish and fish trimmings represent a significant and valuable resource. Consequently, it is important that this resource is handled correctly. Dead fish and trimmings must be processed and stabilized quickly before storage. The marine by-products are organic and as such must be treated as fresh products. Our seafood waste management system allows for easy and convenient fish silage.

ArcticFlow has developed an optimized ensiling process for marine by-products. The entire process is controlled by a fully automated PLC-based control system.

Fish silage preparation starts with the by-products and dead fish are ground into a homogeneous and particulate mass with a particle size of less than 5 mm. With our processing plant for dead fish silage, your company can save money and create extra profit from what has previously been waste. When optimal stirring conditions are reached, formic acid is dosed automatically with continuous pH measurement. In this way, the silage has the desired pH, preferably in the 3.2-3.7 range.

When the silage is stabilized at the desired pH level, it is automatically pumped into a storage tank. The user can easily enter the desired set points for pH, grinder tank level, and running times for grinding and stirring via a touch screen. This enables the process to be easily adapted to the individual plant. Moreover, the user can choose between running the process automatically or manually.
