Norfo Automatic block sawing line for fishblocks
Condition: Good, working
The NORFO Automatic Band Saw is developed especially for cutting frozen fillet blocks.
The saw is equipped with a smooth running feed table and solid guide system, which automatically feeds the blocks into saw blade.
In order to ensure maximum strenght and rigidity the saw is designed with a central column and a minimum distance between the blade drums. Together with two efficient blade guides this ensures an exact and quick cutting function. All parts are made of stainless steel and materials approved for the food industry, and saw developed for rational and and efficient cleaning, easy to sawdust.
Quick and safe adjustment is possible when another cutting pattern is required to fit a new production.
The NORFO Automatic Band Saw is provided with a pneumatic tensioning of the blade.

The portion saw is manufactured for cutting slabs from frozen fish fillet blocks into portions. The saw includes a magazine, which can be fed manually or automatically from the NORFO Multi Band Saw (MBS). From the magazine they are taken, one by one, through the sawing section. This has two horizontal upper blade-shafts with rotating sawblades. At first the slabs are cut into rectangular portions.
Saw blades will straighten up between cuts, and thus a long lifetime of the blades is obtained.
Each slab is during the cutting process safely fastened in a nylon carrier. The nylon carriers can be exchanged if portions with other shapes are to be cut.
The cut portions are removed from the carriers by an automatic separator/spreader system for collection, or for delivery to batter/breader, etc.
The mechanical portion separator will make sure that the portions are staggered and completely spread before entering the batter-breader line.
The sawdust from the cutting is removed by a band system for collecting in boxes.
The machine will cut non-tempered blocks, thus save energy and handling.
Since the trapezoid portions are fully spread, no operator is needed behind the machine.
It will cut planks of variable thickness, even 20 mm without breaking portions.
Sawing of rectangular portions of min. 40 mm width is possible by by-passing the second blade shaft.
