Description

Apparat til å bearbeide sild eller annen fisk. Apparatus for processing herring or other fish.

Den foreliggende oppfinnelse vedrører The present invention relates to

et apparat til å bearbeide sild eller annen fisk, inneholdende en i en sluttet bane bevegelig transportør i form av en fryseflate som fastholder fisken ved fastfrysing for å transportere fisken forbi et stasjonært anbragt redskap som ved passasje av fisken kan oppdele eller på annen måte bearbeide fisken mens deler av denne fastholdes fastfrosset til fryseflaten. an apparatus for processing herring or other fish, containing a transporter moving in a closed path in the form of a freezing surface which holds the fish by freezing in order to transport the fish past a stationary device which, when passing through the fish, can divide or otherwise process the fish while parts of this are kept frozen to the freezer surface.

I norsk patent nr. 54 801 er det foreslått In Norwegian patent no. 54 801 it is proposed

en kombinert transportør og fryseflate i form av et varmeledende bånd som samvir-ker med den sylindriske ytterflate på en trommel hvis indre gjennomstrømmes av et frysemedium. I tillegg til disse to elemen-ter som dreies i fellesskap med anlegg mot hverandre for å avtrekke varme fra det ene element til det annet element, kreves det videre et mellomliggende sjikt av et ikke-frysbart medium. Det er inlysende at en slik løsning med tre adskilte komponenter for overføring av varme, det vil si henholdsvis en varmeledende trommel, et sjikt av ikke-frysbart medium og et varmeledende tran-sportbånd, kompliserer apparaturen og re-duserer frysekapasiteten samt varmeøko-nomien. a combined conveyor and freezing surface in the form of a heat-conducting band that interacts with the cylindrical outer surface of a drum whose interior is flowed through by a freezing medium. In addition to these two elements, which are turned together with a bearing against each other in order to extract heat from one element to the other element, an intermediate layer of a non-freezable medium is also required. It is obvious that such a solution with three separate components for the transfer of heat, i.e. respectively a heat-conducting drum, a layer of non-freezable medium and a heat-conducting transport belt, complicates the apparatus and reduces the freezing capacity as well as the heat economy.

Hensikten med den foreliggende oppfinnelse er å komme frem til et enkelt ar-rangement for en kombinert transportør og fryseflate. Dessuten tar mansikte på å oppnå bedre varmeøkonoml og større fry-sekapasitet enn det som hittil har vært mulig å oppnå. The purpose of the present invention is to arrive at a simple arrangement for a combined conveyor and freezing surface. In addition, the aim is to achieve better heat economy and greater freezing capacity than has been possible up to now.

Apparatet ifølge oppfinnelsen er kjen-netegnet ved at den kombinerte transpor- The device according to the invention is characterized by the fact that the combined transport

tør og fryseflate utelukkende består av en jevn sylindrisk ytterflate på en trommel, hvis indre gjennomstrømmes av et frysemedium og at det langs trommelens sylindriske ytterflate, parallelt med trommelens aksialretning er anordnet en avskrapervegg som er innrettet til å avstryke hele trom-melytterflaten for å avskrape de deler av fisken som er fastfrosset til denne samt avskrape eventuelle rim- eller isdannelser. dry and freezing surface exclusively consists of a smooth cylindrical outer surface of a drum, the interior of which is flowed through by a freezing medium and that along the drum's cylindrical outer surface, parallel to the drum's axial direction, a scraper wall is arranged which is designed to wipe the entire drum outer surface in order to scrape off the parts of the fish that are frozen to it and scrape off any frost or ice formations.

Ytterligere trekk ved oppfinnelsen vil fremgå av den etterfølgende beskrivelse under henvisning til den medfølgende tegning, hvor: Fig. 1 viser skjematisk et apparat ifølge Further features of the invention will be apparent from the following description with reference to the accompanying drawing, where: Fig. 1 schematically shows an apparatus according to

oppfinnelsen, sett fra siden.the invention, seen from the side.

Fig. 2 viser et lengdesnitt gjennom Fig. 2 shows a longitudinal section through

apparatet ifølge fig. 1.the device according to fig. 1.

Apparatet som vist på tegningen er utstyrt med en trommel 10 som. er dreibart lagret om en horisontal akse i lågere 11, 12. Trommelen er dreibar i urviserretningen i fig. 1, slik som vist med en pil 13. Radialt utenfor trommelen 10 på dennes venstre si-de i fig. 1 er det antydet en båndtranspor-tør 14 for tilførsel av fisk som skal bear-beides i apparatet på trommelens motsatte side, hvor det er plasert et fiskebearbei-dingsredskap i form av en båndsag eller båndkniv 15. Båndkniven er innrettet til å avdele et passende tykt sjikt av fisken, for eksempel fjerne fiskeskinnet fra selve fis-kekjøttet eller et benholdig sjikt fra det øvrige fiskekjøtt. The apparatus as shown in the drawing is equipped with a drum 10 which. is rotatably stored about a horizontal axis in bearings 11, 12. The drum is rotatable in the clockwise direction in fig. 1, as shown with an arrow 13. Radially outside the drum 10 on its left side in fig. 1, a belt conveyor 14 is indicated for the supply of fish to be processed in the apparatus on the opposite side of the drum, where a fish processing tool in the form of a band saw or band knife 15 is placed. The band knife is designed to separate a suitable thick layer of the fish, for example removing the fish skin from the fish meat itself or a bony layer from the other fish meat.

Trommelen 10 er utstyrt med en sylindrisk mantel 16 hvis ytterflate 17, som er jevn og glatt, danner anlegg for fisk 18 som skal transporteres ved hjelp av trommelen fra påleggingsstedet 19 til bearbeidingsstedet 20. The drum 10 is equipped with a cylindrical casing 16 whose outer surface 17, which is even and smooth, forms a facility for fish 18 to be transported by means of the drum from the application site 19 to the processing site 20.

Trommelen 10 kjøles ved at der gjennom hule aksler 21, 22 med pakkbokser 23, 24 bringes kjølemiddel inn i et kammer 25 i trommelens indre. Som kjølemiddel kan enten benyttes direkte fordampende kjøle-væske eller en kan pumpe sekundært kjøle-middel som saltlake og liknende igjennom;. The drum 10 is cooled by bringing coolant through hollow shafts 21, 22 with packing boxes 23, 24 into a chamber 25 inside the drum. As a coolant, either directly evaporating coolant can be used or a secondary coolant such as brine and the like can be pumped through;.

Uttaket 26 for frysemiddel fra trommelens indre er, som vist på tegningen, plasert et vesentlig stykke over trommelens akse for å sikre god avkjøling av trommelen ved dennes øvre parti. The outlet 26 for freezing agent from the inside of the drum is, as shown in the drawing, placed a considerable distance above the axis of the drum to ensure good cooling of the drum at its upper part.

Det store hulrom i trommelen, som vist på fig. 2, kan eventuelt reduseres, særlig ved anvendelse av kostbare frysemidler. For eksempel kan det anbringes forholdsvis smale kanaler innenfor trommelens man-telflate. The large cavity in the drum, as shown in fig. 2, can possibly be reduced, particularly when using expensive freezing agents. For example, relatively narrow channels can be placed within the outer surface of the drum.

Ved hjelp av frysemidlet som strømmer gjennom trommelens 10 indre, vil trommelens ytterflate 17 bli raskt nedkjølt til under frysepunktet og vil derved danne en fryseflate som ganske raskt vil fastfryse fisk som plaseres an mot fryseflaten. Fisken 18 tilføres i det viste eksempel sideveis og er vist i tverrsnitt med åpnet buk og oppdelt, slik at hele fiskens skinnside 35 kan brettes ut og legges jevnt an mot fryseflaten 17. With the help of the freezing agent that flows through the interior of the drum 10, the outer surface 17 of the drum will be quickly cooled to below the freezing point and will thereby form a freezing surface which will quite quickly freeze fish that is placed against the freezing surface. In the example shown, the fish 18 is fed sideways and is shown in cross-section with the belly opened and divided, so that the entire skin side 35 of the fish can be unfolded and placed evenly against the freezing surface 17.

Under drift plaseres fisk 18 som frem-føres på båndtransportøren 14 ved påleggingsstedet an mot trommelflaten 17, slik som vist ved 18a. På grunn av fuktigheten som hefter seg til fisken, for eksempel etter en forutgående vaskeoperasjon, vil fisken straks begynne å fryse fast til trommelflaten 17. Ved stillingen 18b er det plasert en trykkrull 30 av skumplast eller lig-nende ettergivende materiale som presser fisken jevnt an mot fryseflaten. Når fisken har passert stillingen 18c er den såpass fastfrosset at den vil fastholdes i et sikkert grep ved 18d når den passerer båndkniven 15 på bearbeidingsstedet 20. Ved å regulere båndknivens radiale avstand fra trommelflaten 17 etter behov, slik som antydet med pilene 36, kan man skjære eller sage fiskeskinnet 37 av fra fiskekjøttet 38 i et jevn-tykt sjikt. Like under båndkniven er det oppstillet en opptakelsesrenne 39 for fiske-kjøttet som er skilt fra fiskeskinnet. Fiskeskinnet som er fastfrosset til fryseflaten 17, fortsetter ennå et stykke på trommelen, men ved trommelens nedre ende er det plasert et avskraperredskap 40 som ligger jevnt an mot trommelens ytterflate og skraper fiskeskinnet nøyaktig av fra flaten 17. Fiskeskinnet faller herved ned i en renne 41 som er plasert like ved rennen 39. During operation, fish 18 which is carried forward on the belt conveyor 14 at the place of application is placed against the drum surface 17, as shown at 18a. Due to the moisture adhering to the fish, for example after a previous washing operation, the fish will immediately begin to freeze to the drum surface 17. At position 18b, a pressure roller 30 made of foam plastic or similar yielding material is placed which presses the fish evenly against the freezing surface. When the fish has passed the position 18c, it is so frozen that it will be held in a secure grip at 18d when it passes the band knife 15 at the processing location 20. By regulating the radial distance of the band knife from the drum surface 17 as needed, as indicated by the arrows 36, one can cut or saw the fish skin 37 off from the fish meat 38 in an even-thick layer. A receiving chute 39 for the fish meat that has been separated from the fish skin is set up just below the band knife. The fish skin, which is frozen to the freezing surface 17, continues for a short distance on the drum, but at the lower end of the drum, a scraping device 40 is placed which rests evenly against the outer surface of the drum and precisely scrapes the fish skin off the surface 17. The fish skin thereby falls into a chute 41 which is placed close to chute 39.

Det er mulig å plasere flere fisker ved siden av hverandre regnet i trommelens akseretning og la disse passere en felles eller eventuelt hver sin eller hver sine bear-beidingsredskaper. Herved kan den manu-elle arbeidskraft utnyttes i større grad. It is possible to place several fish next to each other in the axial direction of the drum and let them pass through a common or possibly separate processing tools. In this way, manual labor can be utilized to a greater extent.
