- the conveying elements 3a, 3b of the conveyor 3 are placed horizontally parallel to each other at a distance from each other.
- the conveying elements 3a, 3b consist of two endless belts 30, 31, rollers 32, 33, around which the belts run, and runners 34 serving to maintain a suitable distance between the belts.
- the runners 34 are preferably turnably mounted on the casing and loaded by springs so that they press the belts 30, 31 towards the supporting element, enabling the belts to grip the fish to be conveyed between them.
- the fish cleaning apparatus comprises an elongated supporting element 4.
- the latter comprises a pipe 5 which is provided with holes 6 placed at a dis ⁇ tance from each other over a suitable range, preferably on the upper side of the pipe 5.
- the pipe 5 is connected to a source 7 of pressurized water, e.g. the normal water distribution system, using suitable connecting pipes 28.
- the pressurized water is effectively directed via the holes 6 in the upper part of the pipe 5 towards the dorsal bone of the opened fish.
- the supporting element 4 comprises a guide 8, which is an elongated component of a width increasing in the downward direction, in this case consisting of a pair of protrusions 8a, 8b laid parallel to the sup ⁇ porting element 4.
- the pipe 5 belonging to the supporting element 4 consists of two parts: the first pipe section 5a and the second pipe section 5b.
- the pipe sections 5a, 5b are linked by the guide protrusions 8a, 8a laid parallel to the supporting element. Between the protrusions is an elongated opening 9 in the vertical direction. Through this opening, the first brushing device 10 cleans the interior of the fish.
- the first brushing device comprises two conse ⁇ cutive rotary brushes 11, 12 with axial quills 13 for brushing the interior of the fish.
- the rotary brushes 11, 12 are rotated by their shafts by a suitable power means, e.g. an electric motor 16.
- the electric motor 16 is coupled to the shaft 14 of one 11 of the rotary brushes, which transmits the power to the other brush via a suitable power transmission means, e.g. a belt.
- the apparatus further comprises a second brush- ing device 17, which in the example represented by the drawings is located at the output end of the cleaning apparatus.
- the brushing device 17 comprises two cylin ⁇ drical brushes 18, 19, which are preferably somewhat wider at the upper end than at the lower end.
- the brushes 18, 19 are supported by essentially vertical shafts 20, 21, which are rotated by a power means, e.g. an electric motor 22.
- the brushes 18, 19 are placed on either side of the supporting element 4 outside the coverage area of the conveyor 3.
- the second brushing device 17 is used for the cleaning of the exterior of the fish.
- Both the first brushing device 10 and the sec- ond brushing device 17 can be provided with nozzles 26, 27 respectively, communicating via suitable connecting pipes 28a, 28b with the source 7 of pressurized water.
- the nozzle 26 serving the first brushing device 10 is preferably placed between the two consecutive rotary brushes 11, 12.
- the cleaning efficiency of both brushing devices can be improved by means of water jets.
- the apparatus further comprises a feeder 23, which is connected to the supporting element 4 at the input end of the conveyor.
- the feeder 23 is an extension of the supporting element 4 and is mounted in an inclin ⁇ ed position such that it has a declivity from the free end towards the supporting element 4 and the conveyor 3.
- the fish are placed with their open ventral side down onto the feeder 23, along which they will easily slide to the input end of the conveyor 3.
- the feeder is also provided with a guide, e.g. protrusions 23a, 23b connected to corresponding protrusions 8a, 8b of the supporting element 4.
- the end of the supporting element 4 is bent to an angle so that it has a slight declivity in the feed di ⁇ rection immediately after the second brushing device 17.
- a conveyor or a separate box can be provided under the output end of the supporting element 4.
- the lower part of the protective casing 2 of the fish cleaning apparatus preferably consists of a basin-like part 2a.
- the water and the cleaning refuse from the fish are collected in this part and removed via an outlet 29.
- the apparatus of the invention works as follows.
- the opened and gutted fish are placed on the feeder 23 with their ventral side down so that the dorsal bone rests on the feeder, whereupon the fish are pushed or allowed to slide into the space between the conveying elements 3a, 3b of the conveyor 3.
- the conveyor 3 pulls the fish along the supporting element 4 and par ⁇ ticularly along the pipe 5, jets of water being simulta- neously discharged through the holes 6 into the interior • parts of the fish K (Fig. 3) while the guide 8 spreads the ventral side of the fish open.
- the water pressure and the rubbing effect arising from the fish sliding along the pipe 5 and the protrusions 8a, 8b result in at least partial cleaning of the fish.
- the second pipe section 5b of the supporting element 4 is preferably also connected to the source 7 of pressurized water via a connecting pipe 28. Consequently, the interior of the fish is continuously washed while the fish are conveyed by the conveyor. However, internal washing is not strictly necessary at this stage.
- the fish are cleaned externally by means of the second brushing device 17.
- the fish delivered from between the conveying elements 3a, 3b of the conveyor 3 are fed in between the cylindrical brushes 18, 19 of the second brushing device 17, which are pressed against the fish and brush them vigorously (Fig. 5) , moving the fish out of the cleaning apparatus.
- the fish fall down from the inclined part of the supporting element 4 e.g. into a suitable transport box.
- the fish to be cleaned are supplied into the cleaning apparatus in a continuous stream, resulting in a fast cleaning process.
- the operation of the fish cleaning apparatus can be adjusted in many ways.
- the water pressure of the source of pressurized water can be adjusted if necessary.
- the position of the first brushing device 10 relative to the supporting element 4 can be adjusted, allowing the brushing range of the rotary brushes 11, 12 to be set to suit the species of fish to be cleaned.
- the cylindrical brushes 18, 19 of the second brushing device are adjustable relative to the supporting element 4, and their distance from the supporting parts can be varied.
- the horizontal distance between the conveying elements 3a, 3b of the conveyor 3 can be varied depending on the species of fish to be cleaned.
