Description
457 929 l0 15 20 25 30 35 2 syresnö bildas, på vilket skikt produkterna är anbring- bara för kontakt med skiktet under en för ytfrysningen erforderlig tid. 457 929 l0 15 20 25 30 35 2 oxygen snow is formed, on which layer the products are applied only for contact with the layer under one for the surface freezing required time.
Behållaren är lämpligen tràgformad och bandtranspor- tören har en första brytrulle vid en ände av behållaren, i vilken ände bädden av kolsyresnö är belägen.The container is suitably trough-shaped and belt conveyor. the dryer has a first breaking roller at one end of the container, at which end the bed of carbon dioxide snow is located.
Bandtransportören kan vidare ha en andra brytrulle vid en andra ände av behållaren, så att transportbandet bildar en övre bana, längs vilken produkterna transpor- teras pâ bandet, och en undre bana, där bandet närmast den första brytrullen medbringar kolsyresnö mot denna.The belt conveyor may further have a second breaker roller at a second end of the container, so that the conveyor belt forms an upper path, along which the products are transported teras on the belt, and a lower lane, where the belt is closest the first break roller carries carbon dioxide snow against it.
Bädden av kolsyresnö sträcker sig lämpligen endast utmed en del av bandets övre bana från den första rullen räknat. bryt- För tillförsel av kolsyresnö till bädden, allt eftersom kolsyresnön i denna förbrukas, kan ett mun- stycke vara anordnat åtminstone i en sidovägg till be- hàllaren. I Genom sättet och anordningen enligt uppfinningen uppnås således en snabb och skonsam ytfrysning av det undre skiktet hos produkterna, vilka därefter kan pla- ceras på transportbandet i exempelvis en spiralfrysare med genombrutet transportband för slutfrysning i denna utan att produkterna fryser fast på slutfrysarens tran- sportband eller får intryck av detta.The bed of carbon dioxide snow suitably extends only along part of the upper path of the band from the first the roll counted. breaking For supplying carbon dioxide snow to the bed, everything since the carbon dioxide snow in it is consumed, a be arranged at least in a side wall to be hàllaren. IN By the method and the device according to the invention thus a rapid and gentle surface freezing of it is achieved the lower layer of the products, which can then be ceras on the conveyor belt in, for example, a spiral freezer with openwork conveyor belt for final freezing in it without the products freezing on the transport of the final freezer sports bands or get the impression of this.
En utföringsform av anordningen enligt uppfinningen skall beskrivas närmare i det följande under hänvisning till bifogade ritning, som schematiskt visar ett längd- snitt av en förfrysaranordning enligt uppfinningen.An embodiment of the device according to the invention will be described in more detail below with reference to the accompanying drawing, which schematically shows a longitudinal section of a freezer device according to the invention.
Den på ritningen visade förfrysaren består närmare bestämt av en balja l, i vilken en bandtransportör med tvâ brytrullar 2, 3 och ett genombrutet transportband 4 är monterad. Baljan l är vid änden med brytrullen 2 fylld med en bädd 5 av kolsyresnö. Vid transportbandets 4 rörelse i den med pilar angivna riktningen kommer kolsyresnön i bädden S att bilda ett tunt, plant skikt 6 över transportbandets 4 övre del närmast brytrullen 2. l0 15 20 25 457 929 3 För tillförsel av ny kolsyresnö till bädden 5, allt eftersom kolsyresnön förbrukas, är ett munstycke 7 anordnat i åtminstone den ena av baljans l väggar.The freezer shown in the drawing is closer determined by a tub 1, in which a belt conveyor with two breaker rollers 2, 3 and an openwork conveyor belt 4 is mounted. The tub 1 is at the end with the break roller 2 filled with a bed 5 of carbonated snow. At the conveyor belt 4 movement in the direction indicated by arrows will carbon dioxide snow in bed S to form a thin, flat layer 6 over the upper part of the conveyor belt 4 closest to the breaking roller 2. l0 15 20 25 457 929 3 For supply of new carbon dioxide snow to bed 5, as the carbon dioxide snow is consumed, is a nozzle 7 arranged in at least one of the walls of the tub 1.
Vid utnyttjande av förfrysaren enligt uppfinningen, varvid transportbandet 4 är i rörelse i den med pilar angivna riktningen, nedlägges produkter 8 styckevis pâ skiktet 6 närmast brytrullen 2. Härvid kommer ett tunt lager närmast den undre sidan av varje produkt att snabbt frysas genom den direkta kontakten med kol- syresnön. Skiktet 6 ovanpå transportbandet 4 rör sig tillsammans med transportbandet och medbringar därvid produkterna 8 under kontakt med dessa under en för yt- frysning av produkternas undre sida erforderlig tid.When using the freezer according to the invention, wherein the conveyor belt 4 is in motion in it with arrows specified direction, products are closed 8 in pieces on the layer 6 closest to the breaking roller 2. In this case, a thin layer closest to the lower side of each product to be quickly frozen by direct contact with coal oxygen snow. The layer 6 on top of the conveyor belt 4 moves together with the conveyor belt and bring with it the products 8 in contact with them during a surface freezing of the lower side of the products required time.
När produkterna 8 har förflyttats förbi bädden 5 av kolsyresnö, faller kvarvarande kolsyresnö på bandet 4 ned i baljan l och föres av bandet 4 i dettas undre bana tillbaka mot brytrullen 2, så att kolsyresnön hela tiden hàlles samlad i bädden 5 intill brytrullen 2.When the products 8 have been moved past the bed 5 off carbon dioxide snow, the remaining carbon dioxide snow falls on the belt 4 down into the tub 1 and is carried by the belt 4 in its lower part path back towards the breaker roller 2, so that the carbon dioxide snow is whole the time is kept collected in the bed 5 next to the break roller 2.
Efter det att produkterna 8 har ytfrysts på sin undre sida och lämnat skiktet 6 transporteras de i direkt kontakt med transportbandet 4 fram till brytrullen 3, varifrån de kan överföras på lämpligt sätt till en slut- frysare, exempelvis en spiralfrysare med ett likaledes genombrutet transportband.After the products 8 have been surface frozen on their lower side and left the layer 6, they are transported in directly contact with the conveyor belt 4 up to the breaking roller 3, from which they can be suitably transferred to a final freezer, for example a spiral freezer with a likewise openwork conveyor belt.
Det inses, att den ovan beskrivna förfrysaren enligt uppfinningen är en mycket kompakt enhet, som kan kombi- neras med vilken som helst slutfrysare för produkterna, samt att den mycket snabbt och skonsamt åstadkommer en ytfrysning av produkternas undre sida.It will be appreciated that the freezer described above according to the invention is a very compact unit which can be combined with any final freezer for the products, and that it achieves very quickly and gently a surface freezing of the lower side of the products.
