Description
Den foreliggende oppfinnelse vedrører en fremgangsmåte for varmebehandling av nymelket melk for avliving av bakterier og mikroorganismer av den art som er angitt i innledningen til det etterfølgende selvstendige krav 1. The present invention relates to a method for heat treatment of freshly milked milk to kill bacteria and microorganisms of the kind specified in the introduction to the following independent claim 1.
Oppfinnelsen vedrører videre en anordning for varmebehandling av nymelket melk for avliving av bakterier og mikroorganismer, av den art som er angitt i innledningen til det etterfølgende anordningskrav 2. The invention further relates to a device for heat treatment of freshly milked milk to kill bacteria and microorganisms, of the type specified in the introduction to the subsequent device requirement 2.
Det har lenge vært kjent å varmebehandle melk og lignende for avliving av bakterier og mikroorganismer. Slik varmebehandling utføres som regel i meierier og lignende anlegg, dit melken føres fra produsentene. Den i dag mer ut-bredte tankoppbevaring som har til formål å rasjonalisere og nedsette antall henteturer, har imidlertid medført den ulempe at melk kommer til å bli oppbevart forholdsvis lang tid før den utsettes for varmebehandlingen på meieriet. Til tross for at oppbevaringstankene er kjølte, kan bakterietilvekst oppstå, noe som ikke kan aksepteres hverken fra hygienisk syns-punkt eller med hensyn til kvaliteten av melken eller av produkter fremstilt av melken. Det kan i denne sammenheng nevnes at allerede et meget lite volum geitemelk som er bakterieangrepet, og som innblandes i et større volum melk, kan gjøre hele melkevolumet utjenlig for ostefremstilling. It has long been known to heat treat milk and the like to kill bacteria and microorganisms. Such heat treatment is usually carried out in dairies and similar facilities, where the milk is taken from the producers. The nowadays more widespread tank storage, which aims to rationalize and reduce the number of collection trips, has, however, resulted in the disadvantage that milk will be stored for a relatively long time before it is exposed to the heat treatment at the dairy. Despite the fact that the storage tanks are chilled, bacterial growth can occur, which cannot be accepted either from a hygienic point of view or with regard to the quality of the milk or of products made from the milk. In this context, it can be mentioned that even a very small volume of goat's milk which is infected with bacteria, and which is mixed into a larger volume of milk, can make the entire volume of milk unsuitable for cheese making.
Grunnen til nevnte bakterietilvekst er at det kan inntreffe store bakteriellle forandringer i melken i forbindelse med den langsomme nedkjøling i konvensjonelle lagringstanker og under tankbiltransporten til meieriet. Årsaken til disse bakterielle forandringer synes til en stor del å være at avliving av bakterier og mikroorganismer med den kjente teknikk, ikke skjer på et tidlig stadium. The reason for the aforementioned bacterial growth is that large bacterial changes can occur in the milk in connection with the slow cooling in conventional storage tanks and during tanker transport to the dairy. The reason for these bacterial changes appears to be to a large extent that the killing of bacteria and microorganisms with the known technique does not occur at an early stage.
Det finnes et omfattende undersøkelsesmateriale There is extensive research material
som entydig viser at tidlig varmebehandling av melk har positive effekter med hensyn til å hindre bakterielle forandringer i melken, hvilket fremgår av en artikkel ved Zajac et al., Milchwissenschaft 38 (11), 1983, side 645 - 648. Ved således å varmebehandle nymelket melk umiddelbart, elimineres i alt vesentlig forutsetningene for bakterietilvekst i melken, which unequivocally shows that early heat treatment of milk has positive effects with regard to preventing bacterial changes in the milk, which is evident from an article by Zajac et al., Milchwissenschaft 38 (11), 1983, pages 645 - 648. By thus heat treating the new milk milk immediately, the prerequisites for bacterial growth in the milk are essentially eliminated,
helt frem til meieriet, hvor den skal viderebehandles. all the way to the dairy, where it will be further processed.
Formålet med oppfinnelsen er å tilveiebringe en The purpose of the invention is to provide a
fremgangsmåte og en anordning som reduserer faren for bakterietilvekst på et så tidlig stadium i håndteringskjeden som mulig. Dette er ifølge den foreliggende oppfinnelse oppnådd ved hjelp av de trekk som fremgår av karakteristikken til det etter-følgende selvstendige fremgangsmåtekrav 1, samt av karakteristikken til det etterfølgende selvstendige anordningskrav 2 med etterfølgende uselvstendige krav. method and a device that reduces the risk of bacterial growth at as early a stage in the handling chain as possible. According to the present invention, this has been achieved by means of the features that appear from the characteristic of the subsequent independent method claim 1, as well as from the characteristic of the subsequent independent device claim 2 with subsequent non-independent claims.
Ved at anordningen ifølge oppfinnelsen plasseres In that the device according to the invention is placed
i tilknytning til melkeapparatene, kan melken umiddelbart etter melkingen varmebehandles, hvorved faren for bakterietilvekst i lagringstanken reduseres i størst mulig utstrekning. En følge av dette er at melken kan oppbevares vesentlig lengre tid i tanken og at følgelig antall hentinger kan reduseres og tidsmellomrommet mellom hentingene økes. En fordel med dette er at endog produsenter med små dyrebesetninger kan utnytte de åpenbare fordeler tankoppbevaring medfører. En ytterligere fordel med anordningen ifølge oppfinnelsen ligger i at denne gjennom sin oppbygning krever et minimalt energitilskudd. in connection with the milking machines, the milk can be heat-treated immediately after milking, whereby the risk of bacterial growth in the storage tank is reduced to the greatest possible extent. A consequence of this is that the milk can be stored for a significantly longer time in the tank and that consequently the number of collections can be reduced and the time interval between collections increased. An advantage of this is that even producers with small animal herds can take advantage of the obvious benefits of tank storage. A further advantage of the device according to the invention lies in the fact that, through its structure, this requires a minimal energy supplement.
Oppfinnelsen kommer i det følgende til å bli nærmere beskrevet med henvisning til den etterfølgende tegning som i et skjematisk perspektivriss viser en foretrukket utførelses-form av anordningen. In the following, the invention will be described in more detail with reference to the subsequent drawing which shows a preferred embodiment of the device in a schematic perspective view.
På tegningen er medtatt kun detaljer som er vesentlige for klargjøring av anordningens funksjon idet ålment brukte komponenter som er aktuelle i denne sammenheng, er utelatt for klarhets skyld. In the drawing, only details are included that are essential for clarifying the device's function, as commonly used components that are relevant in this context have been omitted for the sake of clarity.
Den viste utførelsesform av anordningen ifølge oppfinnelsen er beregnet å være innkoplet mellom et melkeanlegg M og fortrinnsvis etter dettes sluttenhet eller samlebeholder og en oppbevaringstank T. The shown embodiment of the device according to the invention is intended to be connected between a milk plant M and preferably after its end unit or collection container and a storage tank T.
I anordningen inngår en av tre deler bestående varmeveksler 1, et oppholdskar 2, en elektrisk'vannvarmer 3 med sirkulasjonspumpe samt ikke vist termostatorgan og reguleringsutstyr, og til- og avløpsledninger 4,5 for kjøle-vann og forsynt med nødvendige ventiler. The device includes a heat exchanger 1 consisting of three parts, a holding tank 2, an electric water heater 3 with circulation pump as well as a thermostat and control equipment not shown, and inlet and outlet lines 4,5 for cooling water and provided with the necessary valves.
Varmeveksleren utgjøres i den foretrukne utførelses-form av en platevarmeveksler anordnet for motstrømsvarme-veksling. In the preferred embodiment, the heat exchanger is a plate heat exchanger arranged for counter-flow heat exchange.
Varmevekslerens oppvarmingsdel 6 omfatter rom som gjennomstrømmes av melk eller væske som skal behandles, og av rom som gjennomstrømmes av varmt vann og er atskilt av platene. The heat exchanger's heating part 6 includes rooms through which milk or liquid to be treated flows, and rooms through which hot water flows and is separated by the plates.
Vannet oppvarmes i vannvarmeren 3 og sirkuleres mellom denne og varmevekslerens del 6 ved hjelp av en pumpe 7. Vannvarmeren er forsynt med elektriske varmeelementer, hen-siktsmessig et som virker konstant for å holde temperaturen hovedsakelig innen det beregnede temperaturområde og et termo-statstyrt element for justering av temperaturen til eksakt ønsket verdi. The water is heated in the water heater 3 and is circulated between this and the heat exchanger part 6 by means of a pump 7. The water heater is equipped with electric heating elements, preferably one that works constantly to keep the temperature mainly within the calculated temperature range and a thermo-stat controlled element for adjustment of the temperature to the exact desired value.
Til forskjell fra kjente varmebehandlingsanordninger er denne beregnet å bli tilført nymelket melk, dvs; melk som ikke er kjølt. Melken holder altså 34-37°C allerede når den gjennom tilførselsledningen 8 kommer inn i den med 9 betegnede regenerativdel av varmeveksleren. Melken passerer ved 10 rett gjennom kjøledelen 11. In contrast to known heat treatment devices, this one is intended to be fed to freshly milked milk, i.e.; milk that is not chilled. The milk therefore holds 34-37°C already when it enters the regenerative part of the heat exchanger through the supply line 8, denoted by 9. The milk passes at 10 straight through the cooling part 11.
I regenerativdelen 9 oppvarmes melken fra 34-37°c til ca. 50°C ved at varme opptas fra tidligere oppvarmet melk som allerede har passert oppvarmingsdelen 6 og det i strømnings-retningen sett etter denne anordnede oppholdskar 2. Fra regenerativdelen 9 passerer melken inn i oppvarmingsdelen 6 der den kommer i kontakt med de av det varme vann oppvarmede plater og varmes opp til beregnet temperatur ca. 72°C. In the regenerative part 9, the milk is heated from 34-37°c to approx. 50°C by the fact that heat is taken up from previously heated milk which has already passed the heating part 6 and, in the direction of flow seen after this arranged holding vessel 2. From the regenerative part 9, the milk passes into the heating part 6 where it comes into contact with those of the hot water heated plates and heated to the calculated temperature approx. 72°C.
Oppvarmingen av melken skjer altså i to trinn. I det første trinn skjer oppvarming fra begynnelsestemperatur 34-37°C til en temperatur av størrelsesorden 50°C ved at varme fra utgående melk tas vare på. I det andre trinn skjer oppvarming fra 50°c til 72°C ved varmeopptagelse fra det i vannvarmeren 3 oppvarmede vann. The heating of the milk thus takes place in two stages. In the first stage, heating takes place from an initial temperature of 34-37°C to a temperature of the order of 50°C by taking care of heat from outgoing milk. In the second stage, heating takes place from 50°C to 72°C by absorbing heat from the water heated in the water heater 3.
Da melken må holdes ved den høye temperatur i en viss tid for at beregnet dreping av bakterier og lignende skal oppnås, er oppholdskaret 2 anordnet etter oppvarmingsdelen 6. I den foretrukne utførelsesform består oppholdskaret av en rør- eller slangeslynge som er koplet til oppvarmings-delens utløp 11 og munner ut i et passasjerør 12 som strekker seg tvers gjennom oppvarmingsdelen 6. Ved at oppholdskaret er utformet som en slynge, kan dette varieres etter de rådende behov. Bestemmende for holdekarslyngens 2 lengde er strømningen, dvs. volum melk pr. tidsenhet som passerer gjennom anordningen, og den ønskede oppholdstid. As the milk must be kept at the high temperature for a certain time in order for the calculated killing of bacteria and the like to be achieved, the holding vessel 2 is arranged after the heating part 6. In the preferred embodiment, the holding vessel consists of a tube or hose loop which is connected to the heating part's outlet 11 and opens into a passenger pipe 12 which extends transversely through the heating part 6. As the holding vessel is designed as a loop, this can be varied according to the prevailing needs. The length of the holding vessel loop 2 is determined by the flow, i.e. volume of milk per unit of time that passes through the device, and the desired residence time.
Hvis kravet er at melken skal holdes ved en temperatur på 72°C i f.eks. 15 sekunder, avpasses lengden til oppholdskarslyngen 2 slik at det kreves 15 sekunder for et visst kvantum melk å passere slyngen. If the requirement is that the milk must be kept at a temperature of 72°C in e.g. 15 seconds, the length of the holding vessel loop 2 is adjusted so that it takes 15 seconds for a certain amount of milk to pass through the loop.
Oppholdskaret er avgjørende for anordningens funksjon og er det som bestemmer anordningens kapasitet. The holding vessel is crucial for the device's function and is what determines the device's capacity.
Omvendt gjelder at man ved å justere slyngelengden, kan justere inn enhver anordning for en gitt strømning forut-satt at den ligger innen varmevekslernes og vannvarmerens kapasitet. Conversely, by adjusting the length of the coil, you can adjust any device for a given flow, provided that it is within the capacity of the heat exchangers and the water heater.
Fra oppholdskarslyngen føres melken via passasjerøret 13 tilregenerativdelen der den avgir varme til innkommende melk før den får passere gjennom kjøledelen 11, hvori den ved hjelp av kjølevann som kommer inn gjennom ledningen 4 og løper ut gjennom ledningen 5, kjøles til beregnet oppbevaringstemperatur. From the holding vessel loop, the milk is led via the passenger pipe 13 to the regenerative part where it emits heat to the incoming milk before it is allowed to pass through the cooling part 11, in which it is cooled to the calculated storage temperature with the help of cooling water that enters through line 4 and runs out through line 5.
Den omstendighet at anordningen tilføres allerede varm - nymelket - melk og gjennom regenerativ varmeveksling gjenutnytter varme fra allerede varmebehandlet melk, medfører at det nødvendige energitilskudd blir lite. Man kan i denne sammenheng regne med at det kreves en effekt på ca. 5 watt pr. liter behandlet melk. The fact that the device is supplied with already warm - freshly milked - milk and through regenerative heat exchange reuses heat from already heat-treated milk means that the required energy supplement is small. In this context, it can be assumed that an effect of approx. 5 watts per liters of processed milk.
Melken har når den passerer inn i kjøledelen 9 en temperatur av størrelsesorden 40°C og kjøles der til 4-10°C. When the milk passes into the cooling part 9, it has a temperature of the order of 40°C and is cooled there to 4-10°C.
Ledningen 14 fra kjøledelen kan være direkte for-bundet til en i og for seg kjent oppbévaringstank, i hvilken melken altså løper inn nedkjølt til beregnet oppbevaringstemperatur. The line 14 from the cooling part can be directly connected to a storage tank known per se, into which the milk thus flows cooled to the calculated storage temperature.
Det forbrukte kjølevann hvis temperatur er forhøyet med 20-25°C, kan nyttes som drikkevann for kreaturbesetningen eller oppbevares i en spesiell tank fra hvilken det forvarmede The spent cooling water, whose temperature has been increased by 20-25°C, can be used as drinking water for the livestock or stored in a special tank from which the preheated
vann tilføres en varmtvannsbereder for forbruksvann. water is supplied to a water heater for domestic water.
Det største anvendelsesområdet for anordningen ifølge oppfinnelsen beregnes å være i kombinasjon med tankhåndtering av melk. Anordningen er imidlertid i like høy grad anvendbar i det tilfellet man ønsker å distribuere melken direkte fra produsent til forbrukere/videreforhandlere. I et slikt tilfelle koples anordningen til en pakkeenhet som direkte pakker melken. The largest area of application for the device according to the invention is calculated to be in combination with tank handling of milk. However, the device is equally applicable in the event that one wishes to distribute the milk directly from the producer to consumers/retailers. In such a case, the device is connected to a packaging unit that directly packages the milk.
I en noe modifisert utførelse, spesielt når det gjelder kjøledelen, kan anordningen ifølge oppfinnelsen anvendes på det med tank utstyrte kjøretøy som henter melken fra produsenttankene. Melk som fylles i kjøretøytanken blir da automatisk i forbindelse med overpumpingen varmebehandlet, hvilket medfører at en eventuell i produsenttanken påbegynt bakterietilvekst avbrytes og besmitting av den øvrige melk i kjøretøytanken forhindres. In a somewhat modified version, especially with regard to the cooling part, the device according to the invention can be used on the tank-equipped vehicle that collects the milk from the producer tanks. Milk that is filled in the vehicle tank is then automatically heat-treated in connection with the overpumping, which means that any bacterial growth that has begun in the producer tank is interrupted and contamination of the other milk in the vehicle tank is prevented.
