GR 1000 Ensilage Unit™

GR1000 Ensilage system is the smallest and simplest solution for effective grinding and mixing of fish to ensilage. The operator put the fish or fish waste in the tank, close the lid, and start the machine on a timer. Formic acid must be dosed into the tank to give the mass a pH level of 3.5. The enzymes in the fish will start to break down the cells, and the finished product will be a stable protein soup with no bacteriological activity.
