Apparat til automatiseret rengøring af fisk 5 Den foreliggende frembringelse angår et apparat til automatiseret rengøring af kropshulen af fisk, der kontinuert transporteres i en transportretning. 10 Baggrund Ved rensning af fisk, hvorunder de løse indvolde i kropshulen udtages manuelt eller maskinelt, efterlades der i første omgang dels blod og rester fra de løse indvolde, dels nogle fastsiddende indvolde i kropshulen, herunder nyrestrengen, svømmeblæren og eventuelt en indvendig hinde i kropshulen. Det foretrækkes derfor, fx for at gøre fisken mere tilberedningsklar og tiltalende for forbrugeren, eller for at klargøre fisken til videre forarbejdning, at der foretages en rengøring af kropshulen, hvorunder i det mindste en del af de nævnte efterladte dele fjernes fra kropshulen Dette kan udføres manuelt med en børste og en vandstråle, men det foretrækkes at 15 foretage rengøringen maskinelt. 20 Fra GB 1 390 314 kendes et apparat, hvor en fisk fremføres over et værktøj, som skærer svømmeblæren løs ved at overskære eller bortfræse svømmeblærens forbindelse til kropshulens sider. Tilsvarende kendes til fra US 4,882,811 et apparat, hvor fisk, der er åbnet med et snit i bugen, føres forbi to roterende skiveformede børster, hver med en tilhørende vandstråle, hvor den første, stivere børste ή emer svømmeblæren, mens den anden, mindre stive børste fjerner løse indvoldsdele og anden forurening fra kropshulen. I WO 90/03115 beskrives, hvordan fisk, der er åbnet med et snit i bugen, føres hen over to roterende, skiveformede børster med 25 tilhørende vandstråler, hvorved fiskens kropshule renses. Disse tre kendte apparater har det til fælles, at fiskene fremføres på en transportør, hvor de er orienterede med deres længderetning parallel med transportretningen, dvs. at fiskene ligger hoved mod hale langs transportøren. 30 Der er imidlertid en række fordele ved at orientere fiskene parallelt på transportøren, således at deres længderetning danner en vinkel med transportretningen, fx er 2 DK 2002 00310 U3 vinkelret på denne. Et apparat til automatisk eller delvist automatisk rensning og rengøring af fisk omfatter en transportør til transport af fiskene forbi forskellige behandlingsstationer, og transportøren har af praktiske årsager en maksimal fremføringshastighed, hvorfor en kapacitetsforøgelse eller en pladsmæssig 5 indskrænkning af apparatet fortrinsvis kan opnås ved, at fiskenes længderetning danner en vinkel med transportretningen, i det mindste over en del af apparatets udstrækning. Desuden kan tyngdekraften medvirke til at fjerne overskydende skyllevand og eventuelt også de løse indvolde fia kropshulen af fiskene ved at lade fiskene være helt eller delvist lodret orienterede fia en i det væsentlige vandret 10 forløbende transportør. Fiskenes ændrede orientering i forhold til fremføringsretningen betyder imidlertid, at åbningssnittet i fiskens bug ikke mere er parallelt med fremføringsretningen og at fisken ikke er symmetrisk om fremføringsretningen.Apparatus for automated cleaning of fish 5 The present invention relates to an apparatus for automated cleaning of the body cavity of fish which is continuously transported in a transport direction. 10 Background When cleaning fish, during which the loose viscera are removed manually or mechanically, blood and remnants from the loose viscera are initially left, and partly some stuck viscera in the body cavity, including the renal cord, swim bladder and possibly an internal membrane of the body cavity. . It is therefore preferred, for example, to make the fish more ready for cooking and appealing to the consumer, or to prepare the fish for further processing, that a cleaning of the body cavity is performed, during which at least a portion of said leftover parts are removed from the body cavity. manually with a brush and a water jet, but it is preferred to do the cleaning by machine. 20 GB 1 390 314 discloses an apparatus in which a fish is fed over a tool which cuts the swim bladder by cutting or milling the swim bladder's connection to the sides of the body cavity. Similarly, from US 4,882,811, an apparatus in which fish opened with a cut in the abdomen is passed by two rotating disc-shaped brushes, each with an associated jet of water, the first stiffer brush ή emerging the swim bladder, while the second, less rigid brush removes loose parts and other contamination from the body cavity. WO 90/03115 describes how fish opened with a cut in the abdomen are passed over two rotating, disc-shaped brushes with 25 associated water jets, thereby clearing the fish's body cavity. These three known devices have in common that the fish are fed on a conveyor where they are oriented with their longitudinal direction parallel to the transport direction, ie. that the fish are head to tail along the conveyor. 30 However, there are a number of advantages of orienting the fish parallel to the conveyor so that their longitudinal direction forms an angle with the conveying direction, for example 2 DK 2002 00310 U3 is perpendicular thereto. An apparatus for automatic or partially automatic cleaning and cleaning of fish comprises a conveyor for transporting the fish past various processing stations, and for practical reasons the conveyor has a maximum feed rate, which is why a capacity increase or a space restriction of the apparatus can preferably be achieved by longitudinal direction forms an angle with the transport direction, at least over part of the extension of the apparatus. In addition, gravity can help remove excess rinsing water and possibly also the loose viscera through the body cavity of the fish by leaving the fish fully or partially vertically oriented through a substantially horizontal conveyor. However, the changed orientation of the fish relative to the feed direction means that the opening section of the fish's belly is no longer parallel to the feed direction and that the fish is not symmetrical about the feed direction.

Det er et problem af modificere de eksisterende værktøjer til rensning og rengøring 15 af fiskene eller udvikle nye værktøjer, således at de er tilpasset fiskenes ændrede orientering i forhold til fiemføringsretningen. Én løsning er, at drive transportøren på start-stop vis, men dette begrænser apparatets kapacitet væsentligt. En anden løsning er, at vende fisken så de er orienteret parallelt med transportretningen ved visse arbejdsstationer, specielt ved kropshulerengøringsstationen, men dette kræver 20 kompliceret og følsom mekanik, der dels er omkostningsfuldt i anskaffelse og vedligeholdelse, dels kræver øgede ydre dimensioner af stationerne da fiskene strækker sig over en større længde. Disse problemer har medført, at apparater, hvor fiskene er orienterede med en vinkel til fiemføringsretningen, kun er udviklet og markedsført i begrænset omfang.It is a problem of modifying the existing tools for cleaning and cleaning the fish or developing new tools so that they are adapted to the changing orientation of the fish according to the direction of feeding. One solution is to operate the conveyor in a start-stop manner, but this significantly limits the capacity of the device. Another solution is to turn the fish so that they are oriented parallel to the direction of transport at certain workstations, especially at the body cavity cleaning station, but this requires 20 complicated and sensitive mechanics which are costly in procurement and maintenance and partly require increased external dimensions of the stations as the fish extending over a greater length. These problems have led to the fact that devices where the fish are oriented at an angle to the direction of feed are only developed and marketed to a limited extent.

Det er et særligt formål med den nærværende frembringelse at tilvejebringe et apparat til automatiseret rengøring af kropshulen af fisk, der er anbragt parallelt på en kontinuert drevet transportør, hvor fiskenes længderetning danner en vinkel med transportretningen.It is a particular object of the present invention to provide an apparatus for automated cleaning of the body cavity of fish arranged parallel to a continuously driven conveyor, the longitudinal direction of the fish forming an angle with the direction of transport.

30 3 DK 2002 00310 U330 3 DK 2002 00310 U3

Formålet er opfyldt med apparatet til rengøring af kropshulen af fisk i overensstemmelse med frembringelsen, hvilket apparat omfatter en transportør til transport af fisk i en transportretning, hvor transportøren omfatter en flerhed af holdere til hver at holde en fisk på en sådan måde, at fiskenes S længderetning er i det væsentlige parallelle og har en fast vinkel til transportretningen, transportørdrivmidler, der driver transportøren med en i det væsentlige konstant fremføringshastighed, en renseenhed, der omfatter et renseorgan og renseorgandrivmidler, der 10 selektivt kan bevæger renseorganet i længderetningen af fisk, der er arrangeret i holderne, og styreorganer til at styre renseorgandrivmidleme således, at renseorganet føres ind i kropshulen af en fisk arrangeret i en holder, renseorganet aktiveres og bevæges i fiskens længderetning og endelig føres ud af fiskens kropshule.The object is met with the apparatus for cleaning the body of fish in accordance with the production, which apparatus comprises a conveyor for transporting fish in a conveying direction, the conveyor comprising a plurality of holders for holding a fish each in such a way that the fish longitudinal direction is substantially parallel and has a fixed angle to the conveying direction, conveyor propellants driving the conveyor at a substantially constant feed rate, a cleaning unit comprising a cleaning means, and cleaning means propelling means which can selectively move the longitudinal cleaning means of fish which are arranged in the holders, and control means for controlling the cleaning organ propellants such that the cleaning means is introduced into the body cavity of a fish arranged in a holder, the cleaning means is activated and moved in the longitudinal direction of the fish and finally carried out from the body of the fish.

Ved at kunne bevæge renseorganeme parallelt med fiskenes længderetning selvom de befinder sig på en transportør i bevægelse i en retning, der har en vinkel til fiskenes længderetning, opnås det, at apparatet kan rengøre fiskene under drift af transportøren. Det er endvidere fordelagtigt, hvis renseorgandrivmidleme selektivt 20 yderligere kan bevæge renseorganet ind og ud af det plan, fiskene transporteres i, således, at skader på fiskenes sider og buglappeme undgås, når rengøringen med renseorganet er færdigt, og renseorganet skal bevæges den modsatte vej af fisken for at være klar til næste rensning, et arrangement, der ikke er nødvendigt i de kendte apparater.By being able to move the cleaning means parallel to the longitudinal direction of the fish, even if they are on a moving conveyor in a direction that has an angle to the longitudinal direction of the fish, it is achieved that the apparatus can clean the fish during operation of the conveyor. Furthermore, it is advantageous if the cleaning agent propellants can selectively further move the cleaning means in and out of the plane in which the fish are transported, so that damage to the fish's sides and the flaps is avoided when cleaning with the cleaning means is completed and the cleaning means must be moved the opposite way by the fish to be ready for the next cleanse, an arrangement not necessary in the known apparatus.

2525

Det er særligt foretrukken, at holderne er indrettet, så fiskenes længderetning i det væsentlige er vinkelret på transportretningen, hvorved fiskene kan pakkes optimalt tæt i transportretningen.It is particularly preferred that the holders are arranged so that the longitudinal direction of the fish is substantially perpendicular to the direction of transport, whereby the fish can be packed optimally tightly in the direction of transport.

30 Renseorgandrivmidleme omfatter i en særlig udførelsesform et første middel til at bevæge renseorganet parallelt med transportretningen med samme hastighed som 4 DK 2002 00310 U3 transportørens fremføringshastighed, et andet middel til at bevæge renseorganet vinkelret på transportretningen og et tredje middel til at bevæge renseorganet ind og ud af det plan, fiskene transporteres i. De nævnte første, anden og tredje midler kan fx være pneumatiske cylindre, men også fx hydrauliske cylindre eller elektriske 5 lineære eller drejelige aktuatorer kan tænkes anvendt.In a particular embodiment, the cleaning drive propellants comprise a first means for moving the cleaning means parallel to the conveying direction at the same speed as the conveying speed of the conveyor, a second means for moving the cleaning member perpendicular to the transporting direction and a third means for moving the cleaning means in and out. The first, second and third means may, for example, be pneumatic cylinders, but also for example hydraulic cylinders or electric linear or pivot actuators may be used.

Det foretrækkes, at renseorganet omfatter en i det væsentlige skiveformet børste, der ved aktivering bringes til at rotere ved hjælp af særlige drivorganer, og hvis kant føres ind i fiskens kropshule. Alternativt kan der anvendes skærende, skrabende eller 10 fræsende indretningerIt is preferred that the cleaning means comprise a substantially disc-shaped brush which, upon activation, is caused to rotate by means of special drive means and the edge of which is inserted into the body of the fish. Alternatively, cutting, scraping or milling devices may be used

For at øge ydel seseffektiviteten af apparatet er det fordelagtigt at renseenheden omfatter mindst to, gerne tre parallelle renseorganer med en indbyrdes afstand i transportretningen der svarer til holdemes indbyrdes afstand i samme retning, og 15 hvor renseorgandrivmidleme individuelt og selektivt dels kan bevæge hvert renseorgan ind og ud af det plan, fiskene transporteres i, dels kan bevæger hvert renseorgan i længderetningen af fisk, der er arrangeret i holderne, og hvor styreorganeme kan styre renseorgandrivmidleme således, at renseorganeme føres ind i kropshuleme af fisk arrangeret i nabostillede holdere, renseorganeme aktiveres og 20 bevæges i fiskenes længderetning og endelig føres ud af fiskens kropshule.In order to increase the performance efficiency of the apparatus, it is advantageous for the cleaning unit to comprise at least two, preferably three parallel cleaning means with a distance in the transport direction corresponding to the distance between the holders in the same direction, and where the cleaning means can individually and selectively move each cleaning means in and out of the plane in which the fish is transported, in part, each cleaning means can move longitudinally of fish arranged in the holders, where the control means can control the cleaning organ propellants such that the cleaning means are introduced into the body cavities of fish arranged in adjacent holders, the cleaning means are activated and 20 move in the longitudinal direction of the fish and finally move out of the body of the fish.

Renseenheden kan yderligere med fordel omfatte mindst én indretning til at tilføre vand til fiskens kropshule under rensningen af denne, fx i form af en hård vandstråle, der i sig selv har en rengørende effekt ved sammenstødet med fiskens kropshule.The cleaning unit may further advantageously comprise at least one device for supplying water to the fish's body cavity during its cleaning, for example in the form of a hard jet of water which itself has a cleaning effect upon impact with the fish's body cavity.

2525

Endeligt er det en fordel, hvis renseorgandrivmidleme er indrettet til at bevæge renseorganet både frem og tilbage i fiskens længderetning under rensning af fiskens kropshule.Finally, it is an advantage if the cleaning organ propellants are adapted to move the cleaning means both back and forth in the longitudinal direction of the fish while cleaning the body of the fish.

De vedlagte figurer 1 og 2 viser henholdsvis en sideopstalt og en perspektivistisk gengivelse af et apparat ifølge frembringelsen.The accompanying Figures 1 and 2 show, respectively, a side elevation and a perspective view of an apparatus according to the invention.

Apparatet består af et stel 1 opbygget af profilrør, på hvilket stel kædehjul til at bære 10 en transportør 2 med et antal ækvidistant placerede skåle 3 er placeret, hvor hver skål 3 er indrettet til at holde en fisk så fiskens længderetning, dvs. hoved-hale retning, er vinkelret på transportøren 2's fremdriftsretning, der på figur 1 er ind i figurens plan på højre side og ud af figurens plan på venstre side. Indføringen (ikke vist) til indføring af fisk på transportøren 2 består af en keglestub udført i rustfast stål samt 15 nogle lagkageformede emner, hvor fiskene føres ind i indføringen.The apparatus consists of a frame 1 made up of profile tubes, on which the frame sprocket for carrying 10 a conveyor 2 with a plurality of equidistantly placed bowls 3 is placed, where each bowl 3 is arranged to hold a fish so the longitudinal direction of the fish, ie. main-tail direction, is perpendicular to the forward direction of the conveyor 2, which in Figure 1 is in the plane of the figure on the right side and out of the plane of the figure on the left side. The insert (not shown) for introducing fish onto the conveyor 2 consists of a cone stub made of stainless steel and 15 some layer cake-shaped items where the fish are introduced into the insert.

Omgivet af en afdækning 4 er placeret en nyrestrengsrenser 5, der består af tre parallelle børster 6, 6\ 6", der er placeret med samme afstand i transportørens ffemdriftsretning som skålene 3's indbyrdes afstand i samme retning, således, at tre fisk kan behandles samtidigt. De tre børster 6, 6', 6" er ophængt i en fælles ramme 7, 20 der kan forskydes i transportørens fremdriftsretning ad to faste spor 8, 8' ved hjælp af en pneumatisk cylinder (ikke vist). Hver børsteophæng 9, 9', 9" er ophængt i en skinne 10,10', 10" på rammen 7 og kan forskydes ad denne vinkelret på de faste spor 8, 8' ved hjælp af hver sin pneumatiske cylinder (ikke vist). Børsterne 6, 6', 6” er forbundet til børsteophængene 9,9', 9" via arme 11, 1Γ, 1Γ og drejeled 12, 12', 12", 25 om hvilke de kan drejes ved hjælp af pneumatiske drejeaktuatorer (ikke vist). Børsterne 6, 6', 6" kan bringes til rotation med hjælp af oliehydrauliske motorer 13, 13', 13" via kædehjul og en rustfri kæde.Surrounded by a cover 4 is a kidney string cleaner 5 consisting of three parallel brushes 6, 6 \ 6 "located at the same distance in the conveyor's five-way direction as the spacing of the bowls 3 in the same direction, so that three fish can be processed simultaneously The three brushes 6, 6 ', 6 "are suspended in a common frame 7, 20 which can be displaced in the conveyor's direction of travel along two fixed grooves 8, 8' by means of a pneumatic cylinder (not shown). Each brush mount 9, 9 ', 9 "is suspended in a rail 10, 10', 10" on the frame 7 and can be displaced perpendicular to the fixed grooves 8, 8 'by means of each pneumatic cylinder (not shown). The bristles 6, 6 ', 6 "are connected to the bristles 9,9', 9" via arms 11, 1Γ, 1Γ and swivels 12, 12 ', 12 ", 25 about which they can be rotated by pneumatic rotary actuators (not shown ). Brushes 6, 6 ', 6 "can be rotated by means of oil hydraulic motors 13, 13', 13" via sprockets and stainless steel chain.

Der kan som drivmidler anvendes oliehydraulik, vandhydraulik, pneumatik og 30 elektriske motorer, og de nødvendige ændringer for at skifte mellem disse drivmidler 6 DK 2002 00310 U3 og tilvejebringe de nødvendige effektforsyninger, fx af olietryk til motorerne 13-13", der driver børsterne 6-6", anses for åbenlyse for en fagmand, og vil ikke blive beskrevet nærmere her.Oil hydraulics, water hydraulics, pneumatics and 30 electric motors can be used as propellants and the necessary changes to switch between these propellants 6 and provide the necessary power supplies, eg of oil pressure to the motors 13-13 "which drives the brushes 6 -6 ", is considered obvious to a person skilled in the art, and will not be described further herein.

5 Driften af apparatet er beskrevet i det følgende. Fiskene ledes vha. slisker hen til slagtelinien, hvori apparatet indgår. Ved indføringen tager en operatør fisken fra slisken og ligger den ind i indføringen. I indføringen skal fiskens mund placeres over et stykke stål for at have fuld kontrol over fisken under hele indføringsprocessen. Når fisken er i indføringen, drejer den fisken op og afleverer den i skålen 3, der er 10 monteret på transportkæden 2.5 Operation of the apparatus is described below. The fish are guided by slips to the slaughter line in which the apparatus is included. At the introduction, an operator takes the fish from the chute and places it in the feed. In the feed, the fish's mouth must be placed over a piece of steel to have complete control over the fish throughout the feeding process. When the fish is in the feed, it turns the fish up and delivers it to the bowl 3, which is 10 mounted on the transport chain 2.

Den første operatør på linien skærer bugen på fisken op fra gattet til hovedet Den næste operatør løsner indvoldene på fisken og flemer samtidig rognen på fisken. Den tredje operatør skærer spiserøret over og fjerner alle indvoldene fra fisken. Fisken er 15 nu klar til at komme ind i nyrestrengsrenseren.The first operator on the line cuts the belly of the fish from the hole to the head The next operator loosens the intestines on the fish and at the same time flips the prey on the fish. The third operator cuts the esophagus and removes all the viscera from the fish. The fish is now 15 ready to enter the kidney string cleaner.

De nævnte manuelle processer kan også udføres helt eller delvist automatiseret, fortrinsvis ved at fisken skæres op med en kniv, såsom en roterende kniv, monteret på en føring, der sikrer at kniven føres langs fiskens længderetning fra hoved mod 20 gat eller fra gat mod hoved, mens fisken samtidig bevæges kontinuert i transportretningen. Kropshulens indvolde løsnes ved gattet af et skærende værktøj og indvoldene fjernes ved sug med en sugestuds, der føres fra gattet mod hovedet, hvor spiserøret overskæres af et skærende værktøj, så indvoldene kan fjernes fuldstændigt. Sugestudsen og i visse udførelsesformer også det/de skærende værktøjer er monteret 25 på en føring, der bevæges i kædens transportretning, således at de nævnte operationer kan udføres, mens fisken samtidig bevæges kontinuert i transportretningen.Said manual processes can also be performed fully or partially automated, preferably by cutting the fish with a knife, such as a rotary knife, mounted on a guide which ensures that the knife is guided along the longitudinal direction of the fish from head to 20 hole or from hole to head. while simultaneously moving the fish continuously in the direction of transport. The bowels of the body cavity are loosened at the hole by a cutting tool and the viscera are removed by suction with a suction nozzle which is guided from the hole to the head, where the esophagus is cut by a cutting tool so that the viscera can be completely removed. The suction nozzle and in certain embodiments also the cutting tool (s) are mounted on a guide which is moved in the transport direction of the chain, so that said operations can be performed while the fish are simultaneously moving continuously in the transport direction.

Transportkæden 2 hvorpå skålene 3 er monteret kører kontinuerlig og skålene 3 kommer derfor med en jævn hastighed ind gennem nyrestrengsrenseren.The transport chain 2 on which the bowls 3 are mounted runs continuously and the bowls 3 therefore enter at a uniform speed through the renal string cleaner.

30 7 DK 2002 00310 U3 Når skålen 3 kommer forbi positionsføleren (ikke vist) aktiveres en første pneumatisk cylinder (ikke vist) og et ”vinkelspyd” føres op mellem to skåle samtidig med at andre cylindere (ikke vist) fører børstene 6, 6\ 6" frem i samme hastighed som transportkæden 2 ad de faste spor 8,8'.30 7 DK 2002 00310 U3 When the bowl 3 passes the position sensor (not shown), a first pneumatic cylinder (not shown) is activated and an "angular skewer" is brought up between two bowls while other cylinders (not shown) guide the brushes 6, 6 \ 6 "forward at the same speed as the transport chain 2 along the fixed tracks 8,8 '.

5 Når positionsføleren aktiveres, aktiveres børstene 6, 6', 6" ligeledes, så de roterer og hver føres af en cylinder ned i hovederae af tre fisk placeret i naboliggende skåle 3. Når sidstnævnte cylinder er kommet ud af sin udgangsposition, åbnes en magnetventil og der kommer vand ud af et rør ved den pågældende børste. Efter 10 behov kan der monteres flere vandrør. 50 ms efter at sidstnævnte cylinder er kommet ud af sin udgangsposition, startes den tværgående bevægelse op langs fisken ad skinnerne 10,10', 10". Denne tid kan dog indstilles efter behov.5 When the position sensor is actuated, the brushes 6, 6 ', 6 "are also actuated to rotate and each are guided by a cylinder into the main channel of three fish located in neighboring bowls 3. When the latter cylinder has come out of its initial position, a solenoid valve is opened. and water comes out of a pipe at the brush in question.After 10 needs more water pipes can be fitted 50 ms after the latter cylinder has come out of its initial position, the transverse movement is started up along the fish along the rails 10,10 ', 10 ". However, this time can be set as needed.

Når den enkelte børste er kommer op til gattet, aktiveres en føler og børstens 15 bevægelse stopper i 10 ms. Denne tid kan også varieres efter behov. Børsten skal fortsat rotere. Når de 10 ms er gået, kører børsten tilbage gennem fisken. Når cylinderen er tilbage i udgangsposition, løftes børsten ud af fisken og magnetventilen til vandet lukker. Når cylinderen er tilbage i udgangsposition, begynder rammen 7 med børster 6, 6', 6" at køre tilbage til udgangsposition. Når cylinderen til den 20 langsgående bevægelse er tilbage i udgangsposition afventes et nyt startsignal fra positionsføleren.When each brush comes up to the hole, a sensor is activated and the movement of the brush stops for 10 ms. This time can also be varied as needed. The brush should continue to rotate. When the 10 ms have elapsed, the brush runs back through the fish. When the cylinder is back in its starting position, the brush is lifted out of the fish and the solenoid valve until the water closes. When the cylinder is left in the starting position, the frame 7 starts with brushes 6, 6 ', 6 "to return to the starting position. When the cylinder for the longitudinal movement is back in the starting position, a new start signal is awaited from the position sensor.

Det er særligt foretrukket, at udgangsrøret gennem hvilken vandet ledes til skylning af fisken, er hængslet ophængt og i samvirke med en kontakt, således at udgangsrøret 25 udgør føleren. Derved opnås en simpel konstruktion og vandet tilledes tæt på gattet til rengøring af dette område.It is particularly preferred that the exit tube through which the water is directed to flush the fish is hinged suspended and cooperate with a contact such that the exit tube 25 constitutes the sensor. This results in a simple construction and the water is fed close to the hole for cleaning this area.

Styringen af de enkelte motorer og andre drivmidler kan foretages forholdsvis simpelt, fx med en PLC-styring, der er passende programmeret.The control of the individual motors and other propellants can be made relatively simple, for example with a PLC control that is appropriately programmed.

30 DK 2002 00310 U3 8 Når fiskene kommer ud af nyrestrengsrenseren bliver de manuelt kontrolleret af en operatør og hvis fisken ikke er helt ren, fjerner operatøren de sidste rester af indvolde. Afslutningsvis vaskes fisken, når skålen kører ind under et brusearrangement.30 DK 2002 00310 U3 8 When the fish come out of the renal string cleaner, they are manually checked by an operator and if the fish is not completely clean, the operator removes the last remnants of the viscera. Finally, the fish is washed as the bowl enters under a shower arrangement.
