Description
APPARAT TIL VARMEBEHANDLING AF NYMALKET MÆLKAPPLICATION FOR HEAT TREATMENT OF NEW MILK MILK
Opfindelsen angår et apparat til varmebehandling af nymal-ket mælk for aflivning af bakterier og mikroorganismer, hvilket apparat omfatter en varmeveksler med en opvarmningsdel, hvori mælken ved hjælp af opvarmet vand kan opvarmes til tilstrækkelig høj temperatur, en regenererings-del udformet på en sådan måde, at varme fra behandlet mælk kan overføres til indkommende mælk, samt et opbevaringskar, hvori mælken kan tilbageholdes i et forud fastsat tidsrum, hvilket apparat er beregnet til at kunne anbringes i umiddelbart tilslutning til et malkningsanlæg.The invention relates to an apparatus for heat treating freshly milked milk for killing bacteria and microorganisms, which apparatus comprises a heat exchanger with a heating part, in which the milk can be heated to a sufficiently high temperature by means of heated water, a regenerating part formed in such a way that heat from treated milk can be transferred to incoming milk, as well as a storage vessel in which the milk can be retained for a predetermined period of time, which apparatus is intended to be placed in immediate connection to a milking plant.
Det har længe været kendt at varmebehandle mælk for at dræbe bakterier og mikroorganismer. En sådan varmebehandling foretages som regel af mejerier og tilsvarende virksomheder, hvortil mælken bringes af producenterne. Nu om dage opbevares mælken i hovedsagen i opbevaringstanke, og formålet hermed er at rationalisere og nedbringe antallet af køreture for at hente mælken. Dette har imidlertid medført den ulempe, at mælken opbevares forholdsvis længe, inden den udsættes for varmebehandlingen på mejeriet. Skønt opbevaringstankene er nedkølet, kan bakterievækst forekomme, og dette kan hverken accepteres udfra et hygiejnisk synspunkt eller med hensyn til kvaliteten hos mælken eller af denne fremstillede produkter. I denne forbindelse kan det oplyses, at selv en meget ringe mængde bakterieangrebet gedemælk, der blandes i et større volumen, kan gøre hele partiet ubrugeligt til ostefremstilling.It has long been known to heat treat milk to kill bacteria and microorganisms. Such heat treatment is usually carried out by dairies and similar companies to which the milk is brought by the producers. Nowadays the milk is mainly stored in storage tanks and the purpose of this is to rationalize and reduce the number of trips to collect the milk. However, this has led to the disadvantage that the milk is stored relatively long before being exposed to the heat treatment at the dairy. Although the storage tanks have cooled down, bacterial growth can occur and this can neither be accepted from a hygienic point of view nor with regard to the quality of the milk or of the products produced. In this connection, it can be stated that even a very small amount of bacteria-infested goat milk, mixed in a larger volume, can render the whole batch useless for cheese making.
Grunden til nævnte bakterievækst er, at der kan indtræffe store bakterielle forandringer i mælken i forbindelse med den langsomme nedkøling i konventionelle opbevaringstanke og under tankbiltransporten til mejeriet. Årsagen til disse bakterielle forandringer synes for en stor del at være, at aflivning af bakterier og mikroorganismer ikke sker på et tidligt stadium med den kendte teknik.The reason for this bacterial growth is that large bacterial changes in the milk can occur in connection with the slow cooling in conventional storage tanks and during the tanker transport to the dairy. The reason for these bacterial changes appears to be largely that the killing of bacteria and microorganisms does not occur at an early stage with the prior art.
Der findes et omfattende undersøgelsesmateriale, som entydigt viser, at tidlig varmebehandling af mælk har positiv effekt med hensyn til at hindre bakterielle forandringer i mælken, hvilket fremgår af en artikel ved Zajac et al., Milchwissenschaft 38 (11), 1983, side 645-648. Ved således at varmebehandle nymalket mælk umiddelbart elimineres i alt væsentligt forudsætningerne for bakterietilvækst i mælken helt frem til mejeriet, hvor den skal viderebehand-les.Extensive research material exists that unequivocally shows that early heat treatment of milk has a positive effect in preventing bacterial changes in milk, as stated in an article by Zajac et al., Milchwissenschaft 38 (11), 1983, pages 645- 648th Thus, by heat-treating freshly milked milk immediately the conditions for bacterial growth in the milk are eliminated right up to the dairy, where it must be further processed.
Formålet med opfindelsen er at anvise et apparat, der reducerer risikoen for bakterieudvikling på et så tidligt stadium i håndteringskæden som muligt. Problemet er løst ved et apparat af den omhandlede art, hvilket apparat i-følge opfindelsen er særegent ved, at varmeveksleren har en opvarmningsdel, som er indrettet til at kunne overføre varme til mælken fra vand af en bestemt temperatur, at regenereringsdelen har et kar beregnet til at blive gennemstrømmet af den indkommende, ubehandlede mælk under opretholdelse af mælketemperaturen, og et kar beregnet til at blive gennemstrømmet af allerede behandlet, opvarmet mælk, og at opbevaringskarret består af en set i strømningsretningen mellem opvarmningsdelen og regenereringsdelen indrettet ledningsspiral med en med hensyn til kapacitet og nødvendig opholdstid variabel længde.The object of the invention is to provide an apparatus which reduces the risk of bacterial development at the earliest stage in the handling chain as possible. The problem is solved by an apparatus of the present invention, which apparatus according to the invention is peculiar in that the heat exchanger has a heating part which is adapted to transfer heat to the milk from a certain temperature, that the regeneration part has a vessel calculated for flowing through the incoming untreated milk while maintaining the milk temperature, and a vessel intended to be flowed from already treated heated milk, and the storage vessel consisting of a flow direction seen between the heating portion and the regeneration portion arranged with a capacity and required dwell time variable length.
Ved at apparatet ifølge opfindelsen anbringes i tilslutning til malkemaskinen, kan mælken umiddelbart efter malkningen varmebehandles, hvorved risikoen for bakterievækst i opbevaringstanken reduceres stækt. Som følge heraf kan mælken opbevares væsentlig længere i opbevaringstanken, og følgelig reduceres kørselsmængden for afhentning af mælken, ligesom tidsintervallet mellem kørslerne kan øges. En yderligere fordel hermed er, at selv producenter med små besætninger kan opnå de store fordele ved opbevaring i opbevaringstank og endelig er der den fordel ved apparatet ifølge opfindelsen, at det ved sin opbygning kræver et minimum af energi.By placing the apparatus according to the invention adjacent to the milking machine, the milk can be heat-treated immediately after milking, thereby reducing the risk of bacterial growth in the storage tank. As a result, the milk can be stored significantly longer in the storage tank, and consequently the mileage for collection of the milk is reduced, and the time interval between runs can be increased. A further advantage of this is that even small herd producers can obtain the great advantages of storage in a storage tank and finally there is the advantage of the device according to the invention that it requires a minimum of energy in its construction.
Opfindelsen vil i det følgende blive beskrevet med henvisning til vedføjede tegning, der i skematisk perspektiv viser en foretrukken udførelsesform for apparatet ifølge opfindelsen.The invention will be described in the following with reference to the accompanying drawings, which show in schematic perspective a preferred embodiment of the apparatus according to the invention.
På tegningen vises kun for apparatets funktion væsentlige detaljer, og almindeligt forekommende komponenter, som også hører med til konstruktionen, er for overskuelighedens skyld blevet udeladt.The drawing shows only essential details for the function of the apparatus, and common components which also belong to the design have been omitted for the sake of clarity.
Den viste udførelsesform er beregnet på at være indmonteret mellem et malkningsanlæg M og fortrinsvis efter dettes afslutningsdel eller opsamlingsbeholder og en opbevaringstank T. I apparatet findes en af tre dele bestående varmeveksler 1, et opbevaringskar 2, en elvandvarmer 3 med cirkulationspumpe samt ikke-viste termostatorganer og reguleringsindretninger og endelig til- og afløbsledninger 4, 5 med ventiler beregnet på kølevand.The embodiment shown is intended to be mounted between a milking plant M and preferably after its closing part or collection vessel and a storage tank T. The apparatus contains one of three parts heat exchanger 1, a storage vessel 2, an electric water heater 3 with circulation pump and non-shown thermostatic bodies. and control devices and finally supply and drain lines 4, 5 with valves intended for cooling water.
Varmeveksleren består i den foretrukne udførelse af pladevarmevekslere, indrettet for modstrømsvarmeveksling.The heat exchanger consists in the preferred embodiment of plate heat exchangers, arranged for countercurrent heat exchange.
Varmevekslerens opvarmningsdel 6 omfatter kar, der gennemstrømmes af mælk eller væske, der skal behandles, og kar, der gennemstrømmes af opvarmet vand, adskilte af pladerne.The heat exchanger heater portion 6 comprises vessels flowing through milk or liquid to be treated and vessels flowing through heated water separated by the plates.
Vandet opvarmes i vandvarmeren 3 og cirkulerer mellem denne og opvarmningsdelen 6, ved hjælp af en pumpe 7. Vandvarmeren er forsynet med elvarmeelement, fortrinsvis et, der fungerer kontinuerligt for opretholdelse af temperaturen i det ønskede temperaturområde og et termostatstyret element for finjustering af temperaturen til eksakt den ønskede værdi.The water is heated in the water heater 3 and circulates between it and the heating part 6, by means of a pump 7. The water heater is provided with an electric heating element, preferably one which operates continuously to maintain the temperature in the desired temperature range and a thermostatically controlled element for fine-tuning the temperature to exactly the desired value.
Til forskel fra kendte varmebehandlingsapparater er dette beregnet på at arbejde med nymalket mælk, det vil sige mælk, der ikke er nedkølet. Mælken har altså allerede en temperatur af 34-37°C, når den via tilløbsledningen 8 løber ind i den med 9 betegnede regenereringsdel hos varmeveksleren. Mælken passerer ved 10 lige igennem nedkølingsdelen 11.Unlike known heat treatment appliances, this is intended to work with freshly milked milk, ie milk that is not refrigerated. Thus, the milk already has a temperature of 34-37 ° C when it flows into the heat exchanger part of the heat exchanger via the supply line 8. The milk passes at 10 straight through the cooling portion 11.
I regenereringsdelen 9 opvarmes mælken fra 34-37°C til ca. 50°C ved, at varme aftages fra tidligere opvarmet mælk, der allerede har passeret opvarmningsdelen 6 og det set i strømningsretningen efter denne indrettede opbevaringskar 2. Fra regenereringsdelen 9 passerer mælken ind i opvarmningsdelen 6, hvor den kommer i berøring med de af det varme vand opvarmede plader og opvarmes til den ønskede temperatur, ca. 72°C.In the regeneration portion 9, the milk is heated from 34-37 ° C to approx. 50 ° C by removing heat from previously heated milk which has already passed the heating part 6 and that seen in the flow direction after this arranged storage vessel 2. From the regenerating part 9 the milk passes into the heating part 6 where it comes into contact with those of the heat. water heated plates and heated to the desired temperature, approx. 72 ° C.
Opvarmningen af mælken foregår altså i to tempi. I første trin sker opvarmningen fra begyndelsestemperaturen 34-37°C og til en temperatur i størrelsesordenen 50°C ved, at varmen fra udstrømmende mælk genbruges. I andet trin sker opvarmningen ved hjælp af det fra vandvarmeren 3 opvarmede vand. Opbevaringskarret 2 er placeret efter opvarmningsdelen 6, for at mælken skal holdes ved den høje temperatur, der er nødvendig for at bakterier og mirkoorganismer skal dræbes. I den foretrukne udførelse består opbevaringskarret af en rør- eller slangespiral, der er tilsluttet opbevaringsdelens udløb 12 og munder ud i et passagerør 13, der går lige igennem opvarmnings de len 6. Ved at opbevaringskarret er udformet som en spiral, kan det varieres efter de forhåndenværende behov. Afgørende for opbevaringsspiralens længde er den gennemstrømmende mælks volumen per tidsenhed og længden af den tid, man ønsker at opbevare mælken i opbevaringskarret. Hvis kravet er, at mælken skal holdes ved en temperatur af 72° C i for eksempel femten sekunder, tilpasses længden af opbevaringsspiralen 2, så det tager femten sekunder for et vist kvantum mælk at løbe igennem spiralen.Thus, the heating of the milk takes place at two temps. In the first step, the heating takes place from the initial temperature of 34-37 ° C and to a temperature of the order of 50 ° C by reusing the heat from the flowing milk. In the second step, the heating is done by means of the water heated from the water heater 3. The storage vessel 2 is positioned after the heating part 6 to keep the milk at the high temperature needed for bacteria and miracle organisms to be killed. In the preferred embodiment, the storage vessel consists of a pipe or hose coil which is connected to the outlet part 12 of the storage part and opens into a passenger tube 13 which passes straight through the heating elements 6. By storing the storage vessel it can be varied according to the pre-existing needs. The volume of the flowing milk per unit of time and the length of time you want to store the milk in the storage vessel are crucial to the length of the storage spiral. If the requirement is that the milk be kept at a temperature of 72 ° C for, for example, fifteen seconds, the length of the storage coil 2 is adjusted so that it takes fifteen seconds for a certain quantity of milk to pass through the coil.
Opbevaringskarret er af afgørende betydning for apparatets funktion og er det, der bestemmer dets kapacitet.The storage vessel is essential for the operation of the device and is what determines its capacity.
Omvendt gælder, at man ved at justere spiralens længde kan tilpasse ethvert apparat til en given gennemstrømnings-mængde, forudsat at den ligger indenfor varmevekslernes og vandvarmerens kapacitet.Conversely, by adjusting the length of the coil, any apparatus can be adapted to a given flow rate, provided that it is within the capacity of the heat exchanger and the water heater.
Fra opbevaringsspiralen føres mælken via passagerøret 13 til regenereringsdelen, hvor den afleverer varme til indkommende mælk, før den føres gennem nedkølingsdelen 11, hvori den ved hjælp af kølevand, der indføres via ledningen 4 og udløber via ledningen 5, nedkøles "til ønsket opbevaringstemperatur .From the storage coil, the milk is passed through the passenger tube 13 to the regeneration portion, where it delivers heat to the incoming milk, before being passed through the cooling portion 11, whereby it is cooled "to the desired storage temperature by means of cooling water introduced through line 4 and discharged through line 5.
Den kendsgerning, at apparatet tilføres mællt, der allerede er varm (nymalket), og ved regenerering/varmeveksling genbruger varme fra allerede varmebehandlet mælk medfører, at det nødvendige energiforbrug bliver lille. Man kan regne med, at en effekt på ca. fem watt per liter behandlet mælk vil være nødvendig.The fact that the appliance is fed to milk that is already warm (freshly milked) and when regenerating / exchanging heat recycles heat from already heat-treated milk means that the necessary energy consumption becomes small. One can expect that an effect of approx. five watts per liter of treated milk will be needed.
Mælken har, når den føres ud i køledelen 9„ ren temperatur af ca. 40°C og nedkøles der til 4-10°C.When discharged into the cooling portion 9 the milk has a clean temperature of approx. 40 ° C and cooled to 4-10 ° C.
Ledningen 14 fra køledelen kan være direkte tilsluttet en opbevaringstank, hvori mælken føres ind, nedkølet til beregnet opbevaringstemperatur.The conduit 14 from the cooling section may be directly connected to a storage tank into which the milk is introduced, cooled to the intended storage temperature.
Det benyttede kølevand, hvis temperatur er forhøjet med ca. 20-25°C, kan udnyttes som drikkevand til kreaturbesætningen eller eventuelt opbevares i en særskilt tank, hvorfra det forvarmede vand kan overføres til en vandvarmer for brugsvand.The cooling water used, the temperature of which is increased by approx. 20-25 ° C, can be used as drinking water for the livestock herd or possibly stored in a separate tank from which the preheated water can be transferred to a domestic water heater.
Det største anvendelsesområde for apparatet ifølge opfindelsen forventes at være i kombination med tankhåndtering af mælk. Apparatet er imidlertid lige så anvendeligt i de tilfælde, hvor man ønsker og må distribuere mælken direkte fra producent til forbruger/udsalg. I dette tilfælde slut tes apparatet til en indpakningsenhed, der direkte emballerer mælken.The greatest application of the apparatus according to the invention is expected to be in combination with tank handling of milk. However, the appliance is equally useful in cases where you want and have to distribute the milk directly from producer to consumer / retailer. In this case, the appliance is connected to a packaging unit which directly packaging the milk.
I en noget modificeret udførelse, især hvad angår nedkølingsdelen, kan apparatet ifølge opfindelsen anbringes på den tankbil, der henter mælken fra producenttankene. Mælk, der overføres til køretøjstanken, bliver da automatisk varmebehandlet i forbindelse med overpumpningen, hvilket medfører, at eventuel bakterievækst afbrydes, og at smitte af anden mælk i køretøjstanken forhindres.In a somewhat modified embodiment, particularly with regard to the cooling part, the apparatus according to the invention can be placed on the tank truck which fetches the milk from the producer tanks. Milk that is transferred to the vehicle tank is then automatically heat treated in connection with the over-pumping, which means that any bacterial growth is interrupted and that infection of other milk in the vehicle tank is prevented.
Apparatet, der i hovedsagen er indrettet på den her beskrevne måde, kan i og for sig bruges indenfor andre områder end behandling af mælk. Apparatet ifølge opfindelsen kan således anvendes indenfor bryggeriindustrien til aflivning af gærsvampe og almindelig pateurisering af øl og lignende drikkevarer, ligesom af juicer. Også indenfor vinfremstilling kan apparater af denne type anvendes til vinstensudfældning.The apparatus, which is essentially arranged in the manner described herein, can in itself be used in areas other than milk processing. Thus, the apparatus according to the invention can be used in the brewing industry for the killing of yeast fungi and the general paterization of beer and similar beverages, as well as of juices. Even in winemaking, appliances of this type can be used for winepressing.
Indenfor værkstedsindustrien kan apparatet bruges til "pasteurisering" af skærevæsker, hvorved disse kan benyttes gentagne gange, uden at baktericider, der kan forårsage hudsygdomme hos personalet, behøver tilsættes.In the workshop industry, the apparatus can be used for "pasteurization" of cutting fluids, which can be used repeatedly without the need to add bactericides that can cause skin diseases to the staff.
Apparatet kan endelig bruges for eksempel i u-lande til behandling af drikkevand.The device can finally be used, for example, in developing countries for the treatment of drinking water.
