  • Chute 23 is U-shaped and consists of a number of elongated tubular bodies 21 arranged in the direction of travel v. In the example of Fig. 2, the elongated tubular bodies are held in place by a number of brackets 22 engaged with the framework 18 and the elongated tubular bodies 21.
  • the elongated tubular bodies 21 which together form a U-shaped chute 23, causes little sliding friction for fish being transported down the chute 23, and at the same time washing water containing sea lice from fish will be drained off the chute 23.

  • nozzles 16a - 16h are angularly adjustable relative to an angle of downward inclination a. Such angular adjustability makes it possible to optimize the flushing direction so that washing can be efficient without the water pressure having to be increased. Angular adjustability is optional; when the most efficient angles have been determined based on experience, then these angles can be fixed.
  • Fig. 3b also shows a gauge 14.
  • the gauge may be combined with a pressure sensor or replaced by a pressure sensor.
  • Fig. 4a shows a circular nozzle manifold 45.
  • the circular nozzle manifold is similar to the octagonal nozzle manifold 15 shown in Fig. 3a. Note that also in this case the bottom of chute 23 is located in the centre and hence the fish is transported down chute 23 in the direction of travel v in the centre of nozzle manifolds 45.
  • Fig. 4b shows the circular nozzle manifold 45 viewed from the side.
  • the only feature that distinguishes the circular nozzle manifold 45 from the octagonal manifold 15 of Fig. 3b is the shape. Both manifolds surround chute 23.

  • a control loop getting feedback from pressure sensor 64 can ensure an optimal water pressure to the jet nozzles.
  • the signal may also be used for monitoring the pressure in the system.
  • Figs. 6 and 7 show examples of pressure control using a pressure sensor that provides an output signal representative of a pressure.
  • the sensor output of a pressure transmitter will be selectable between 4 - 20 mA, 0 - 5 V, 1 - 5 V, 1 - 6 V, 0 - 10 V and 10 - 90% ratiometrically.
  • the pressure sensor may include additional features provided by microcontrollers that offer diagnostic functions and intelligent performance functions.
  • a variable frequency drive is a type of motor controller that operates an electric motor by varying the frequency and voltage of the power supply.
  • a VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively.
  • the frequency can be correlated with operating parameters from delousing station 10, such as the output signal of one or more pressure sensors.
  • the output signal of pressure sensors can be transformed to frequencies representative of liquid pressure.
  • the frequency drive controls the frequency and voltage supplied to a motor, thus providing speed control of the motor.
  • Figs. 1 - 7 show valves for controlling liquid pressure and liquid flow.
  • one or more pumps may be used for the same purpose. Liquid pressure and liquid flow can be efficiently controlled by way of one or more pumps which control liquid pressure and liquid flow into manifold inlet 11.
  • the pumps used can be controlled by a variable frequency control of an AC induction motor. Variable frequency control provides an economically sound and operationally efficient solution for motor speed control.
  • Fig. 7 is a schematic view of a simple control loop.
  • nozzle manifolds can be oval, for example, or have other shapes, the point being to optimize the washing effect by having a nozzle manifold that surrounds chute 23. Nevertheless, as indicated above, it is not the only advantage that the fish can be washed from all sides; it is also a point that the distance between nozzle and fish is the same from all nozzles of the same nozzle manifold so that the water pressure will be equal on all sides of the fish.
  • Fig. 8 shows a delousing station including three nozzle manifolds. From the figure, it can be seen that the jet direction 83 of water from the nozzles of the first nozzle manifold is partly co-current. For the second nozzle manifold, the direction of the waterjets from nozzles 16 is oriented substantially perpendicular to the direction of travel v. The jet direction 81 of waterjets from the third nozzle manifold is partly against the current.
  • controller 85 may be a frequency converter which converts analogue or digital signals from the pressure sensors into variable frequency signals, whose frequencies are related to the value of the input signal.
  • the frequency converter can be a standard VFD converter.
  • Controller 85 controls the admission to pump 86. Pump 86 receives water from a reservoir 87.
  • valves are controlled by controller 85. If the pressure and amount of liquid into the delousing unit is controlled by controller 85 communicating with pump 86, then valve control will be an option which could provide for individual pressure control in each of the nozzle manifolds 15a, 15b, 15c.
  • Valves 13 are shown to receive admission from controller 85. However, they may also be manual valves. Also, valves 13 may include an actuator that enables control of the valves 13 from controller 85, or alternatively the actuator could be a separate part. The actuator is not shown in any of the drawings.
  • Fig. 9 shows details of a nozzle 16, said nozzle 16 comprising a nozzle tip and a parabolic surface 91 projecting from the underside of the nozzle tip.
  • the curved parabolic surface causes a flow of water from the jet nozzle to be dispersed outwardly and to have a lower pressure than it has when it hits the parabolic surface.
  • the solution contributes to an even and adequate washing pressure over the entire fish to be deloused. In cases where nozzles of a manifold become clogged, it will be a problem that the pressure in an open nozzle will increase and the fish may be subject to a "jet stream" to the skin.
  • the particular solution including a parabolic surface makes sure fish to be deloused are not exposed to jet streams when other nozzles of the system/manifold become clogged.
  • Figs. 1 and 2a show three nozzle manifolds. However, any number from one nozzle manifold to more than three nozzle manifolds can be envisioned.
  • Chute 23 is shown provided with a number of elongated tubular bodies. This is one embodiment of numerous conceivable embodiments. It can be envisioned that chute 23 is formed by an elongated U-shaped plate having a number of openings. Mesh variants are also imaginable.
  • a continuous chute is not used.
  • the delousing station is divided into delousing units, which delousing units are arranged adjacent to each other to form an upper delousing unit and one or more downstream delousing units.
  • Figs. 2b - 2e show details of the second embodiment.
  • the delousing units exhibit a downward inclination a relative to a horizontal plane.
  • the manifold part itself surrounds a lower section of a chute of a delousing unit in the same manner as in the first embodiment of a delousing station.
  • the positioning of the nozzles 16 in a space 26 ensures that washing water from the jet nozzles is not blocked by obstacles between a nozzle 16 and fish to be washed, resulting in an even water pressure on fish to be washed.
  • the nozzles are arranged in such a manner that crossing of nozzle jets is minimized. This is achieved through a selective angling and orientation of nozzles 16, see figs. 2d and 2e.
  • a delousing unit comprises a U-shaped chute.
  • the chute may exhibit parallelly arranged ribs having an angle of downward inclination a relative to a horizontal plane. Whether or not the ribs are parallelly arranged depends on the shape of the chute.
  • the chute is U-shaped, so if the opening of the U varies, then the ribs will not necessarily be parallel.
  • the chute has an upper end and a lower end. At said lower end and surrounding the chute, an endless nozzle manifold 15 is arranged, said endless nozzle manifold being configured so as to project perpendicularly upwards relative to a.
  • Nozzle manifold 15 is arranged so that the nozzles 16 of a manifold 15 are arranged in a space 26 between two adjacent chutes.
  • Nozzle manifolds 15 comprise at least two jet nozzles 16 for delousing fish, of which at least one nozzle 16 is arranged at a vertical level lower than an adjacent lower end of the U-shaped chute. This is clearly apparent from figure 2c, in which the lowermost nozzle 16 is located below the lowermost rib of adjacent chutes.
  • Fig. 2b shows four delousing units.
  • a first, upper delousing unit 25a is shown furthest upstream. Adjacent to this delousing unit 25a, a second delousing unit 25b is arranged downstream of the first upper delousing unit. There is a step height 28 between the first, upper delousing unit 25a and the second delousing unit 25b. Similar step heights 28 exist between adjacent downstream delousing units 25.
  • a third delousing unit 25c is arranged downstream of the second delousing unit 25b.
  • a fourth delousing unit 25d is arranged downstream of the third delousing unit.
  • a delousing station may include fewer or more delousing units.

  • a delousing unit comprises a chute, which chute is held together by two brackets 22, with a single nozzle manifold 15 being arranged adjacent to and surrounding an end of the chute. Nozzles 16 of nozzle manifold 15 have nozzle jets which will not be obstructed by objects when washing fish.
  • Fig. 2c is a sectional view of a delousing unit, showing nozzles 16 and a nozzle manifold. The parabolic surface 91 for nozzles 16 is shown. The figure further shows that nozzles 16 are arranged so as to form a water veil 27. Said water veil 27 shows that water jets are not much dispersed parallel to the v-direction.
  • Fig. 2d shows a perspective sectional view of a delousing station 20.
  • the figure shows nozzle manifolds 15 including nozzles, and water veils 27 from nozzles 16 are shown for the first 15a and second nozzle manifolds 15b.

What distinguishes the first and second embodiments is the sectioning. Where the first embodiment of a delousing station shows a single continuous chute including one or more nozzle manifolds, the second embodiment of a delousing station 20 shows the delousing station to be comprised of two or more delousing units as seen in Fig. 2b.
