Depending on the needle head installed an injector from KAPP can inject both fillets and flat fish. The needle head in the left picture is for fillets, it has fixed needles. Needle head for splitted, see picture to the right, gives needles freedom to lift up if they collide with bones. Each needle has a spring that pushes the needle down.

To reuse brine a filtering solution is needed. This is done using two filter conveyor belts that sit on top of the reservoir tank. The filter belts consist of a coarse filter belt (2mm mesh) and a fine filter belt (1mm mesh). The filter belts only allow liquid that has passed through both belts into the reservoir tank. If the brine needs to be cooled and/or maintain it at a certain temperature, a cooling filter that has a dual layer for coolant, see top left picture. KAPP offers a refrigeration compressor that is capable of maintaining a desired temperature of the brine.

The injector calls for a new mixture when the mixture in the filter is below the minimum level. Valves on the mixing tank and height sensors control the amount of water, brine and additives given in the recipe. If the mixing system is connected to the RAF-IBL dosing station all the additives can be controlled and mixed into the injection machine brine mixture. The system registers what has been mixed during the operation of the day and displays it on a colour touch screen. By using the RAF-SPGraf registration system these data can be stored in a database.

When a tub is put in place in the mixing area the system is automatically switched on and it then mixes the brine mixture selected. The mixing system for the tubs also controls the quantity of the product placed in the tub via a fish rationing conveyor belt and thus it contributes to better utilization.
