Description
509 920 10 15 20 25 30 35 Med fördel komprimeras och kondenseras den avskilda gasen för förnyad användning som kylmedium. 509 920 10 15 20 25 30 35 Advantageously, the separated gas is compressed and condensed for reuse as a cooling medium.
Sättet enligt uppfinningen lämpar sig i synnerhet väl om emulsionen eller suspensionen användes för framställning av ett livsmedel varvid den använda gasen är livsmedels- godkänd. Som sådan gas utnyttjas företrädesvis koldioxid.The method according to the invention is particularly suitable if the emulsion or suspension is used for the preparation of a foodstuff in which the gas used is food-grade. As such gas, carbon dioxide is preferably used.
Särskilt fördelaktigt blir detta om emulsionen eller suspensionen är en svårkyld viskös massa.This will be particularly advantageous if the emulsion or suspension is a viscous mass which is difficult to cool.
Sättet enligt uppfinningen lämpar sig synnerligen väl då suspensionen utgöres av en fettemulsion avsedd för fram- ställning av ett bredbart matfett. Även då den nämnda suspensionen utgöres av en livsmedels- blandning innehållande partikulärt material erhålles avsevärda fördelar. Som exempel på sådana blandningar kan nämnas frukt- eller grönsaksblandningar i egen juice eller saft, såsom t.ex. tomattärningar i juice. Blandningen kan också bestå av kött eller fiskbitar i sås.The method according to the invention is particularly well suited when the suspension consists of a fat emulsion intended for the production of a spreadable edible fat. Even when the said suspension consists of a food mixture containing particulate matter, considerable advantages are obtained. Examples of such mixtures are fruit or vegetable mixtures in own juice or juice, such as e.g. tomato cubes in juice. The mixture can also consist of meat or fish pieces in sauce.
En anordning för genomförande av sättet vid kontinuerlig kylning enligt uppfinningen omfattar huvudsakligen ett inlopp för kondenserad gas och ett inlopp för pumpbar emulsion eller suspension, vilka inlopp både mynnar i en zon med begränsad volym för att skapa momentan kontakt mellan kondenserad gas och emulsionen eller suspensionen.A device for carrying out the method of continuous cooling according to the invention essentially comprises an inlet for condensed gas and an inlet for pumpable emulsion or suspension, which inlets both open into a zone with limited volume to create instantaneous contact between condensed gas and the emulsion or suspension.
Med fördel finns nämnda zon anordnad i en förångningsventil eller i en förångningskammare ansluten till en separations- kammare.Advantageously, said zone is arranged in an evaporation valve or in an evaporation chamber connected to a separation chamber.
Nämnda separationskammare står via en ledning i förbindelse med en kompressor för komprimering av gasen. lO 15 20 25 30 35 509 92of Enligt uppfinningen är nämnda separationskammare lämpligen förbunden med ytterligare en separationskammare vilken ytterligare kammare har ett utlopp som står i förbindelse med en andra kompressor.Said separation chamber is connected via a line to a compressor for compressing the gas. According to the invention, said separation chamber is suitably connected to a further separation chamber, which further chamber has an outlet which communicates with a second compressor.
Med fördel står åtminstone en av kompressorerna via en ledning i förbindelse med en kondensor vilken i sin tur via en ytterligare ledning står i förbindelse med en förråds- tank för kondenserad gas från vilken tank den kondenserade gasen recirkuleras för förnyad föràngning.Advantageously, at least one of the compressors is connected via a line to a condenser which in turn is connected via an additional line to a storage tank for liquefied gas from which tank the liquefied gas is recirculated for re-evaporation.
Vid sättet enligt uppfinningen bringas alltså en konden- serad gas att förångas i en pumpbar massa bestående av en suspension eller emulsion. Genom att den kondenserade gasen så gott som omedelbart förångas erhålles en mycket snabb kylning av den pumpbara massan. Vilken gas som skall väljas beror naturligtvis av den avsedda applikationen och dess kylbehov samt de konstnader kylsteget kan bära. Skall en mera exklusiv produkt snabbt kylas från t.ex. en viss behandlings- eller blandningstemperatur vid eller strax över rumstemperatur kan eten, freoner eller C02 komma ifråga. Skall kylningen ske vid högre temperaturer väljes en annan gas, såsom propan, etan eller N43, som kondenserar vid en högre temperatur.In the method according to the invention, a condensed gas is thus caused to evaporate in a pumpable mass consisting of a suspension or emulsion. By evaporating the condensed gas almost immediately, a very rapid cooling of the pumpable mass is obtained. Which gas is to be chosen depends, of course, on the intended application and its cooling needs, as well as the costs that the cooling stage can carry. Should a more exclusive product be quickly cooled from e.g. a certain treatment or mixing temperature at or just above room temperature, ethylene, freons or CO 2 may be considered. If the cooling is to take place at higher temperatures, another gas is chosen, such as propane, ethane or N43, which condenses at a higher temperature.
Skall den pumpbara emulsionen eller suspensionen utnyttjas för framställning av en livsmedelsprodukt måste gasen vara livsmedelsgodkänd. Som sådan är koldioxid att föredra även om det i sig är möjligt att arbeta exempelvis med kväve om så skulle anses önskvärt. Koldioxid kondenserar vid olika temperatur beroende på trycket. Således är kondensations- temperaturen -30°C vid 14 bar, ~ 0°C vid 35 bar och 25°C vid 60 bar. Att arbeta med högre tryck än 40 bar fördyrar vanligen processen i onödigt hög grad. 509 920 10 15 20 25 30 35 |_'> För att kontakten mellan den kondenserade gasen och den massa (emulsion eller suspension) som skall kylas skall bli så intensiv som möjligt, tillföres både kondenserad gas och massa till en zon med begränsad volym t.ex. så att konden- serad gas tillföres till massan genom ett inlopp som mynnar direkt in i en ström av nämnda massa. Omedelbart efter sammanblandningen förångas den kondenserade gasen med medföljande volymökning och den nämnda zonen måste alltså stå i förbindelse med ett utrymme med större volym.If the pumpable emulsion or suspension is to be used for the preparation of a food product, the gas must be food approved. As such, carbon dioxide is preferable even if it is in itself possible to work with nitrogen, for example, if this would be considered desirable. Carbon dioxide condenses at different temperatures depending on the pressure. Thus the condensation temperature is -30 ° C at 14 bar, ~ 0 ° C at 35 bar and 25 ° C at 60 bar. Working with a pressure higher than 40 bar usually makes the process unnecessarily expensive. 509 920 10 15 20 25 30 35 | _ '> In order to make the contact between the liquefied gas and the pulp (emulsion or suspension) to be cooled as intense as possible, both liquefied gas and pulp are supplied to a zone with a limited volume t .ex. so that condensed gas is supplied to the pulp through an inlet which opens directly into a stream of said pulp. Immediately after mixing, the condensed gas evaporates with the accompanying volume increase and the said zone must therefore be connected to a space with a larger volume.
Temperaturen hos massan sänks omedelbart. Till följd av trycksänkningen och expansionen utsätts massan under detta snabba förlopp också för en mekanisk bearbetning till följd av de höga skjuvkrafter som utvecklas. I separations- kammaren sker en trycksänkning och en del av gasen avskiljs.The temperature of the pulp is lowered immediately. As a result of the pressure drop and the expansion, the mass is also subjected to a mechanical processing during this rapid process due to the high shear forces that develop. In the separation chamber, the pressure drops and a part of the gas is separated.
Uppfinningen beskrivs närmare med hänvisning till bifogade ritning som schematiskt visar en som exempel vald utföringsform av en anläggning för kylning av fettemulsion.The invention is described in more detail with reference to the accompanying drawing which schematically shows an exemplary embodiment of a plant for cooling fat emulsion.
En ström av fettemulsion med en temperatur av 35°C leds via en ledning l till en förångningskammare 2. Till denna leds också ett flöde av kondenserad gas via en andra ledning 3.A stream of fat emulsion with a temperature of 35 ° C is led via a line 1 to an evaporating chamber 2. To this is also led a flow of condensed gas via a second line 3.
Den kondenserade gasen, som består av C02 har ett tryck av 40 bar. När den kondenserade gasen kommer in i förångnings- kammaren och sammanförs med fettemulsionen förångas den ögonblickligen med samtidig avkylning av fettemulsionen.The liquefied gas, which consists of CO2, has a pressure of 40 bar. When the condensed gas enters the evaporation chamber and is combined with the fat emulsion, it evaporates instantly with simultaneous cooling of the fat emulsion.
Bildad gas och emulsion leds vidare till en separations- kammare 4 där en trycksänkning sker. Den största delen av den frigjorda C02-gasen avleds via en ledning 5 under ett tryck av 30 bar. Blandningen av fettemulsion och resterande gas bringas av tyngdkraften och trycket i kammaren 4 att passera ett organ 6 som endast medger flöde i en riktning in i en andra kammare 7. I denna andra kammare 7 sker ännu en trycksänkning så att frigjord koldioxidgas lämnar 10 15 20 25 30 UI kammaren med ett tryck av 5 bar genom en ledning 8. Fett- emulsionen bringas att passera ännu ett organ 9 innan den med en temperatur av ca l0°C leds in till en bearbetnings- enhet 10 t.ex. en pinnrotor inför efterföljande paketering.Formed gas and emulsion are passed on to a separation chamber 4 where a pressure drop takes place. Most of the released CO2 gas is diverted via a line 5 under a pressure of 30 bar. The mixture of fat emulsion and residual gas is caused by gravity and the pressure in the chamber 4 to pass a means 6 which only allows flow in one direction into a second chamber 7. In this second chamber 7 another pressure drop takes place so that released carbon dioxide gas leaves In the chamber with a pressure of 5 bar through a line 8. The fat emulsion is passed through another member 9 before it is led at a temperature of about 10 ° C into a processing unit 10 e.g. a pin rotor prior to subsequent packaging.
Organen 6 och 9 kan bestå av pumpar eller ventiler som fungerar som slussorgan som avskiljer separationskamrarna sinsemellan och från den efterföljande bearbetningsenheten.The means 6 and 9 may consist of pumps or valves which act as locking means which separate the separation chambers from each other and from the subsequent processing unit.
Koldioxidgas kan också avledas från bearbetningsenheten 10.Carbon dioxide gas can also be diverted from the processing unit 10.
Koldioxidgasen i ledningen 5 med 30 bars tryck leds till en kompressor ll där trycket höjs till 40 bar. Från denna föres den gasformiga koldioxiden genom en ledning 12, 13 till en kondensor 14. Till kondensorn leds också den komprimerade gasformiga koldioxiden från ledningen 8. Denna gas har komprimerats i en kompressor 15. I kondensorn sänks temperaturen till under 4°C, vilket leder till att gasen kondenseras. Från kondensorn ledes den kondenserade kol- dioxiden till ett förrådskärl 16, som fungerar som balans- kärl. Den mängd koldioxid som krävs för kylningen uttages fràn förràdskärlet 16 och passerar en pump 17 som doserar den kondenserade gasen vid ett tryck av exempelvis 40 bar.The carbon dioxide gas in line 5 at 30 bar pressure is led to a compressor II where the pressure is raised to 40 bar. From this the gaseous carbon dioxide is passed through a line 12, 13 to a condenser 14. To the condenser the compressed gaseous carbon dioxide is also led from the line 8. This gas has been compressed in a compressor 15. In the condenser the temperature is lowered to below 4 ° C, which leads to the gas condensing. From the condenser, the condensed carbon dioxide is led to a storage vessel 16, which functions as a balance vessel. The amount of carbon dioxide required for cooling is taken from the storage vessel 16 and passes through a pump 17 which dispenses the condensed gas at a pressure of, for example, 40 bar.
Den kondenserade gasen blandas med ny fettemulsion, för- ángas ányo och avgàr delvis genom ledningen 5.The condensed gas is mixed with a new fat emulsion, evaporated and partly discharged through line 5.
Kylningen av fettemulsionen sker alltså kontinuerligt och koldioxiden ändrar cykliskt aggregationstillstànd.The cooling of the fat emulsion thus takes place continuously and the carbon dioxide changes the cyclic state of aggregation.
I den visade utföringsformen utnyttjas tvâ kamrar där huvuddelen av den frigjorda koldioxidgasen avleds fràn den första kammaren, separationskammaren. Om så anses önskvärt kan enbart en gemensam kammare med ett gasutlopp utnyttjas.In the embodiment shown, two chambers are used where the main part of the released carbon dioxide gas is diverted from the first chamber, the separation chamber. If considered desirable, only a common chamber with a gas outlet can be used.
Om enbart ett gasutlopp används är C02-gasens tryck lågt vilket underlättar avgasningen av fettemulsionen men processen blir mera dyrbar. 509 920 10 15 20 25 30 6 I det nu visade utföringsexemplet har kondenserad koldioxid med ett tryck av 40 bar använts för kylningen.If only one gas outlet is used, the pressure of the CO2 gas is low, which facilitates the degassing of the fat emulsion, but the process becomes more expensive. 509 920 10 15 20 25 30 6 In the embodiment now shown, condensed carbon dioxide with a pressure of 40 bar has been used for the cooling.
De värden på gastrycket som anges på ritningen utgör endast ett exempel på en för uppfinningen lämplig trycknivà. Många andra alternativ är tänkbara också vid tryck över 40 bar där olika kombinationer av tryck och temperatur hos den kondenserade gasen med värden över 40 bar/4°C kan utnyttjas.The values of the gas pressure given in the drawing are only an example of a pressure level suitable for the invention. Many other alternatives are also conceivable at pressures above 40 bar where different combinations of pressure and temperature of the condensed gas with values above 40 bar / 4 ° C can be used.
Komprimeras den avskilda koldioxiden till ett högre tryck erfordras mindre kylande yta i kondensorn än om trycket är lägre.If the separated carbon dioxide is compressed to a higher pressure, less cooling surface in the condenser is required than if the pressure is lower.
En anläggning av det beskrivna slaget uppvisar stora för- delar gentemot tidigare känd teknik där skrapvärmeväxlare ombesörjt kylningen. Skulle något problem uppstå vid paketeringen avbryts tillförseln av fettemulsion och kondenserad koldioxid till förångningskammaren. När problemet lösts, ofta bara någon minut senare, startar tillförseln på nytt och kylprocessen fortsätter. Mot- svarande avbrott i en anläggning med skrapvärmeväxlare kan leda till att driften stoppar totalt. Först efter rengöring kan àterstart vara möjlig.A plant of the type described has great advantages over previously known technology where scraper heat exchangers take care of the cooling. Should any problem arise during packaging, the supply of fat emulsion and condensed carbon dioxide to the evaporation chamber is interrupted. When the problem is solved, often just a few minutes later, the supply starts again and the cooling process continues. Corresponding interruptions in a system with scraper heat exchangers can lead to the operation stopping completely. Only after cleaning can restart be possible.
Inom ramen för uppfinningen är det möjligt att utnyttja såväl andra livsmedelsgodkända gaser, om den pumpbara massan (emulsionen eller suspensionen) utgörs av en livsmedelsprodukt eller skall vidarebehandlas till en sådan, som andra slags gaser med lämpliga kondensations- temperaturer för andra typer av massor.Within the scope of the invention, it is possible to use other food-approved gases, if the pumpable mass (the emulsion or suspension) consists of a food product or is to be further processed into such, as other types of gases with suitable condensation temperatures for other types of masses.
