Opfindelsen angår et køle- eller fryseapparat af den i krav l's indledning angivne art.The invention relates to a refrigeration or freezing apparatus of the kind specified in the preamble of claim 1.
Inden for fødevareindustrien og lignende virksomheder skal styrtelige produkter fryses enkeltvis på skånsom 5 og økonomisk måde, uden at delene under fryse- eller køleprocessen fryser fast på underlaget, fryser sammen eller får trykskader. Det er kendt at anvende skabe med frugtstativer, langbåndfrysere eller skruefrysere.Within the food industry and similar companies, perishable products must be frozen individually in a gentle and economical manner, without the parts during the freezing or cooling process freezing on the substrate, freezing together or causing pressure damage. It is known to use cabinets with fruit racks, long strip freezers or screw freezers.
Der kendes endvidere tromlefrysere, hvor produkterne, 10 der skal behandles, indføres i en tromle, i hvilken der samtidigt indsprøjtes et kølemiddel. Sådanne tromlefrysere er ufordelagtige ved deres store konstruktionslængde. Desuden er der risiko for, at kølemidlet kun kommer i berøring med én side af produktfyldningen 15 (oversiden).Furthermore, drum freezers are known in which the products to be treated are introduced into a drum in which a refrigerant is simultaneously injected. Such drum freezers are disadvantageous by their large construction length. In addition, there is a risk that the refrigerant will only come into contact with one side of the product filling 15 (top side).
Fra US-A-3 466 030 kendes et apparat til hurtigfrysning af produkter og af den i foreliggende krav l's indledning angivne art. Dette apparat har en ydre tromle, i hvilken der munder et produkttilførselsorgan, og hvori 20 produktet behandles med kølemidlet. Inden i den første tromle findes en anden tromle. Efter at produktet er passeret gennem den første tromle i dennes længderetning, løftes det ved enden af den ydre tromle ved hjælp af medbringerelementer op i det øvre tromleområde, hvor-25 fra det falder ned på en slisk, som skråner ned og ind i den indre tromle. Produktet passerer gennem den indre tromle modsat fremføringsretningen i den ydre tromle og forlader den indre tromle ved samme apparatende, ved hvilken organet til tilførsel af produktet er place-30 ret. De to tromler har hver sin særskilte drivmekanisme.From US-A-3 466 030 an apparatus for rapid freezing of products and of the nature of the preamble of claim 1 is known. This apparatus has an outer drum into which is provided a product feed means and wherein the product is treated with the refrigerant. Inside the first drum is a second drum. After passing the product through the first drum in its longitudinal direction, it is lifted at the end of the outer drum by means of carrier elements into the upper drum area, from which it falls onto a slit which slopes down and into the inner drum. The product passes through the inner drum opposite the direction of feeding into the outer drum and leaves the inner drum at the same apparatus end at which the product supplying means is located. The two drums each have their own separate drive mechanism.
Den foreliggende opfindelse har til formål at tilvejebringe et køle- eller fryseapparat af den i krav l's indledning angivne art med en forenklet overførsel af 2The present invention has for its object to provide a cooling or freezing apparatus of the kind specified in the preamble of claim 1 with a simplified transfer of 2

produktet fra den ene tromle til den anden, hvor behandlingsprocesser kan gennemføres på økonomisk vis, og hvori der sikres en økonomisk udnyttelse af det anvendte kølemiddel. Dette formål opnås ved det i krav 5 l's kendetegnende del angivne. Ifølge opfindelsen an vendes to i hinanden anbragte tromler, der roterer enkeltvis eller tilsammen. De styrtelige produkter ledes først ind i den indre tromle, i hvilken de påvirkes med kulde og videretransporteres under tromlens rota-10 tion, for fra den indre tromle at falde ind i den ydre tromle, hvor produkterne transporteres tilbage modsat fremføringsretningen i den indre tromle. Ved apparatet ifølge opfindelsen overføres produkterne derved, at produkterne, der forlader den indre tromle, falder ind 15 i den ydre tromle. Der kræves således ikke nogen løfte mekanisme. Produkternes opholdstid i den indre tromle kan reguleres ved tilsigtet opdæmning af produkter ved den indre tromles ende. En sådan påvirkning kan tilvejebringes ved hjælp af opdæmningslegemer eller andre 20 indbygningsdele ved den indre tromles udløbsende.the product from one drum to the other, where treatment processes can be carried out economically and where the economical utilization of the refrigerant used is ensured. This object is achieved by the characterizing part of claim 5 l. According to the invention, two spaced drums are used which rotate individually or together. The steerable products are first fed into the inner drum, in which they are affected by cold and transported during the rotation of the drum, to fall from the inner drum into the outer drum where the products are transported back opposite the direction of feeding into the inner drum. In the apparatus according to the invention, the products are transmitted so that the products leaving the inner drum fall into the outer drum. Thus, no lifting mechanism is required. The residence time of the products in the inner drum can be regulated by intentional containment of products at the end of the inner drum. Such influence can be provided by means of containment bodies or other 20 integral parts at the outlet end of the inner drum.
Afhængigt af det anvendte kølemiddels art kan dette indsprøjtes på forskellige steder. Er kølemidlet en luftart, der forbliver gasformig selv i ekspanderet tilstand, indsprøjtes kølemidlet hensigtsmæssigt i den 25 ydre tromle, d.v.s. under produkternes tilbageføring, idet den indre tromle anvendes som forkølestrækning.Depending on the nature of the refrigerant used, this can be injected in different places. If the refrigerant is a gaseous substance which remains gaseous even in the expanded state, the refrigerant is suitably injected into the outer drum, i.e. during the return of the products, using the inner drum as a cooling stretch.
Anvendes som kølemiddel derimod en luftart, der ved ekspansion omdannes til sne, bør luftarten så vidt muligt indsprøjtes i den indre tromle i nærheden af pro- 30 duktinføringsåbningen, så at sneen så tidligt som mu ligt påføres produkterne og følger med disse på deres samlede bane gennem begge tromler. Når kølemidlet indføres i den indre tromle, bliver denne koldere end den ydre tromle, hvorved kuldetabene mindskes og kølemid-35 lets udnyttelse forbedres.On the other hand, if a refrigerant is used as a gas which, when expanded, is transformed into snow, the gas species should as far as possible be injected into the inner drum near the product introduction opening, so that the snow is applied to the products as early as possible and follows them on their entire path. through both drums. When the refrigerant is introduced into the inner drum, it becomes colder than the outer drum, thereby reducing the cooling losses and improving the utilization of the refrigerant.

Ved apparatet ifølge opfindelsen muliggøres ved en forbedret koldgasbortledning en bedre udnyttelse af kulden, så at der som kølemiddel kan anvendes Det er ikke nødvendigt at skille produkterne fra kølemidlet.The apparatus according to the invention enables better utilization of the cold by means of an improved cold gas discharge, so that as a refrigerant can be used It is not necessary to separate the products from the refrigerant.
5 Produkterne kan enten fremføres ved hjælp af tyngde kraften, hvortil den pågældende tromles længdeakse skråner nedad i transportretningen, eller ved mekaniske hjælpemidler såsom snegle eller vinger. Ved anvendelse af mekaniske fremføringsorganer, der er anbragt på trom-10 levæggene, kan der tilvejebringes en supplerende agita tion af produkterne, hvorved risikoen for gensidig sammenfrysning af enkelte produkter modvirkes.5 The products can be conveyed either by the force of gravity, to which the longitudinal axis of the drum in question slopes downwards in the direction of transport, or by mechanical aids such as augers or wings. By using mechanical feeder means arranged on the drum walls, an additional agitation of the products can be provided, thereby counteracting the risk of mutual freezing of individual products.
Tromlernes diameter, omløbstal, hældning og tværsnits-form samt arten af indbygningsdelene kan tilpasses ar-15 ten af de produkter, der skal behandles og disses køle eller rulleegenskaber.The diameter of the drums, the number of turns, the slope and the cross-sectional shape, as well as the nature of the components can be adapted to the nature of the products to be treated and their cooling or rolling properties.
Køle- eller fryseapparatet ifølge opfindelsen er ikke blot velegnet til frysning af f.eks. vegetabilske produkter, men kan f.eks. også anvendes til køling af fær-20 digprodukter såsom hønsekød i terningeform, boller og lignende færdigvarer.The cooling or freezing apparatus according to the invention is not only suitable for freezing e.g. vegetable products, but can e.g. also used for cooling finished products such as diced chicken, buns and similar finished products.
Underkravene kendetegner fordelagtige udførelsesformer for apparatet ifølge opfindelsen.The subclaims characterize advantageous embodiments of the apparatus according to the invention.
I det følgende forklares opfindelsen nærmere ved hjælp 25 af tegningen, hvor fig. 1 er et skematiseret længdesnit i en udførelses-form for køle- eller fryseapparatet ifølge opfindelsen med to i indbyrdes modsat retning nedad skrånende tromler,In the following, the invention is explained in more detail with reference to the drawing, in which fig. 1 is a schematic longitudinal section in one embodiment of the refrigerator or freezer according to the invention with two mutually opposite sloping drums,

Den i fig. 1 viste udførelsesform for køle- eller fry-seapparatet ifølge opfindelsen har en første indre tromle 10 bestående af et ved begge ender åbent cylindrisk 10 rør, hvis akse skråner nedad i fremføringsretningen.The FIG. 1, the refrigeration or freezing apparatus according to the invention shown in Fig. 1 has a first inner drum 10 consisting of a cylindrical tube open at both ends, the axis of which slopes downwardly in the feeding direction.
Tromlens produktindløbsåbning 11 befinder sig ved tromlen 10's højest beliggende ende. Ved denne ende rager en stationær tilførselstragt 12 ind i tromlen 10, der af en ikke vist drivmekanisme roteres om sin længdeak-15 se, hvorved de i tromlen indførte styrtelige produkter på grund af tromlens hældning transporteres i tromlens længderetning ved tyngdekraftens virkning. Produkterne forlader tromlen 10 ved dennes modsatte udløbsende 11a og falder ned i en anden tromle 13, der omgiver den 20 første indre tromle 10, og som ud for den første trom les udløbsende 11a er lukket med en endevæg 14, medens den anden ydre tromle 13 er åben ved sin modsatte ende til dannelse af et produktudløb 13. Denne anden ende af den ydre tromle 13 er beliggende lavere end endevæg-25 gen 14, så at den anden ydre tromle, der ligeledes ro teres, fremfører materialet modsat dettes fremførings-retning i den første indre tromle 10. Produkterne, der passerer ud gennem den anden tromles udløbsende 15, falder ned i en beholder 16, hvorfra de tilføres et 30 ikke vist emballeringsapparat. Den anden tromle 13 er anbragt på lejebukke 17.The product inlet opening 11 of the drum is at the highest end of the drum 10. At this end, a stationary feed hopper 12 projects into the drum 10, which is rotated about its longitudinal axis by a drive mechanism not shown, whereby the controllable products introduced into the drum are transported in the longitudinal direction of the drum by the force of gravity. The products leave the drum 10 at its opposite outlet end 11a and fall into a second drum 13 surrounding the first inner drum 10 and which is closed off the end wall 11a of the first drum with an end wall 14, while the second outer drum 13 is open at its opposite end to form a product outlet 13. This other end of the outer drum 13 is located lower than the end wall 25 so that the second outer drum, which is also rotated, advances the material opposite to its feed direction. in the first inner drum 10. The products passing out through the outlet end 15 of the second drum fall into a container 16 from which they are supplied with a packaging apparatus 30 not shown. The second drum 13 is disposed on bearing blocks 17.

På grund 5 af produkternes rullende bevægelse inde i tromlen 10 påføres der på disse et ensartet snelag. Under produkternes fortsatte passage gennem de to tromler 10 og '13 afkøles produktoverfladen af snelaget på denne.5 18, from which a refrigerant is injected under pressure into the inner drum 10, in the present case carbon dioxide (CO 2) · The refrigerant is converted by expansion in air to snow deposited on the products. Due to the rolling motion of the products within the drum 10, a uniform snow layer is applied to these. During the product's continuous passage through the two drums 10 and '13, the product surface is cooled by the snow layer on it.
Ved den i fig. 2 viste udførelses form er den første 10 indre tromle 10 fast anbragt i den anden tromle 13, koaksialt med denne. Den første tromle 10's produktudløbsåbning 11a er beliggende i aksial afstand fra den anden tromles endevæg 14. De to tromlevægge er ubrudt uden perforati oner. Begge tromlers fælles tromleakse 15 skråner i forhold til vandret, idet den indre tromle 101 s produktindløbsåbning 11 er beliggende højere end denne tromles udløbsåbning 11a. På indersiden af den anden tromle 13' s ydervæg er- anbragt skruegænger 20 eller vinger, der under tromlernes rotation transpor-20 terer materialet til udløbsåbningen 15 ved den anden tromles højest beliggende ende. Kølemiddelledningen 18 udmunder i den indre tromle 10, og kølemidlet (kuldioxid) udsprøjtes i lille afstand fra og efter den første produktindløbsåbning 11.In the embodiment shown in FIG. 2, the first 10 inner drum 10 is firmly disposed in the second drum 13 coaxially with the latter. The product outlet opening 11a of the first drum 10 is located at axial distance from the end wall 14. The two drum walls are unbroken without perforations. The common drum axis 15 of both drums slopes relative to the horizontal, with the inner drum 101 s product inlet opening 11 being located higher than this drum outlet opening 11a. On the inside of the outer wall of the second drum 13 are screw threads 20 or blades which, during rotation of the drums, transport the material to the outlet opening 15 at the highest end of the second drum. The refrigerant line 18 opens into the inner drum 10 and the refrigerant (carbon dioxide) is sprayed at a small distance from and after the first product inlet opening 11.

Tromlerne 10 og 13 er på tegningen vist som cylindri-20 ske rør. Tromlerne kan dog også have i deres længderetning varierende tværsnitsform, idet f.eks. cylindriske tromlevægpartier skifter med polygonale, hvorved man opnår, at produkterne rundtom belægges med C02-sne og gennemfryses hurtigt og på ø’konomisk vis. Desuden hol-25 des de enkelte produkter løse, fordi de på grund af omstyrtningen ikke kan fastfryse ved hinanden.The drums 10 and 13 are shown in the drawing as cylindrical tubes. However, the drums may also have their longitudinal cross-sectional shape varying, e.g. cylindrical drum wall portions alternate with polygonal, thereby ensuring that the products around are coated with CO2 snow and frozen quickly and in an economical manner. In addition, the individual products are kept loose because, due to the overthrow, they cannot freeze together.
