Definitions

• the present invention relates to a method for cutting, gutting and cleaning of farmed fish and a device necessary for implementing the method
• the device receives the whole fish after the fish has bled to death and is ready for cutting, gutting and cleaning Killing of the fish is effected by bleeding, and the fish is let out in a tank of water where it bleeds to death Subsequently, the fish is taken up on benches where it is gutted The fish is then either sent from the gutting bench via a conveyor belt to the cleaning area, or cleaning is effected directly on the gutting bench This is for the personnel an unsuitable and non-rational way of working In addition, such working conditions present a health hazard for the personnel as a result of the mappropiate working posture and the resulting strain injuries.
• Fig 1 is a schematic representation of the device
• Fig 2 is a lateral representation illustrating the vertical placement of the conveyor system for the fish through the device
• Fig 3 is a cross-sectional view of the device at the feed end
• Fig 4 illustrates the principle of the vertical walls of the gutter on the conveyor belt.
• Fig. 5 is a cross-sectional view of the conveyor system.
• Fig. 3 illustrates how the gutters 3 are positioned in two rows along the conveyor belts 4.
• Fig. 1 shows that the operators can easily reach the fish in the gutters 3 on the conveyor belts 4 and the effectiveness is increased in that two fish arrive at the same time in the gutters 3 in front of the operators, although slightly staggered in relation to each other
• the device comprises two entirely separate and parallel conveyor belts 4 running along the outer edges of the device, and the operators sit along each conveyor belt 4.
• This dual conveyor system removes the necessity of a conveyor belt of the same width as the device
• the fish is fed onto the conveyor belts 4 from the trough 1 through the guides 2 by one single operator 1 ' so that each operator of the first pair of operators 5 1 always have a fish to process at any time.
• the first pair of operators 5 1 slit the belly of the fish open and the fish is conveyed further to the second pair of operators 5 who finish gutting the fish and dispose of the guts down a chute 10 positioned either next to the second pair of operators 5 2 or in the middle of the device.
• the fish is then transported to a third pair of operators 5 3 who, with a knife, slit over the fish's throat and kidneys
• the fish is then transported further to a fourth pair of operators 7 1 who remove the fish's heart and kidneys with a kidney suction remover
• the fish is then transported to a fifth 7 2 and a sixth 7 3 pair of operators who clean the fish's abdominal cavity of all blood, gut and fiber remnants with flushing and suction devices.
• a return gutter 6 is provided where fish which is has not been satisfactorily cleaned can be placed and wait for later proper gutting and cleaning
• a flushing box 8 is provided for the fish and the conveyor belts 4
• the conveyor belts 4 bring the fish under a set of nozzles which flush the fish in a normal way Afterwards, the conveyor belts 4 receive additional flushing by a set of nozzles None of those nozzles is shown on the drawings
• the return of the conveyor belts 4, after passing the last roller, is effected via a washing trough 9 which further cleans the conveyor belts 4 before new fish is placed in the gutters 3 at the level of the feed trough 1
• Fig 5 is a cross-sectional view of the two gutters 3 which are found on each conveyor belt 4
• the side walls consist of inverted Y-shaped elements 12
• Y-shaped elements 12 provide a U-shaped cross section for each gutter 3, where the fish remains stable in a belly up position
• Fig S is a lateral view of a conveyor belt 4 illustrating the principle of the flexible side wall design
• the Y-shaped elements 12 which make up the side walls are positioned at a certain distance from one another along the conveyor belt 4, providing a stable support for the fish, and allowing satisfactory flexibility for the conveyor belt 4 to move into another plane or in a curve
• This design provides great flexibility for the conveyor belts 4
