Digital load cells are the key
Teltek's approach involved six parallel buffer plates on each side of the scale, with room for a total of twelve fillets that have passed through the two fish sorters. A combination of fish fillets is selected to come as close as possible to the target weight of 400 grams per pack. The central components of the machine are the six digital HBM PW15AHi single point load cells
, with a pneumatic motor to advance the belt.
"Obviously, the primary function of the machine is weighing, but a lot of thought went into how the fish is handled and transported – this is a delicate raw material that can easily fall apart. We clearly want to keep waste to a minimum", says Tomas Moqvist, who has learned a lot about raw fish during the project.
