Description
Förfarande och arrangemang för värmeväxlíng av vätskor Föreliggande uppfinning avser ett förfarande och arrangemang förvärmeväxling av vätskor i tankar, närmare bestämt för kylning av mjölk. Method and arrangement for heat exchange of liquids The present invention relates to a method and arrangement for pre-heating exchange of liquids in tanks, more specifically for cooling milk.
Ett traditionellt baslivsmedel är mjölk från betande och idisslande djur.Djurhållning med frigående besättningar i öppna djurhallar och öppnalandskap har under de senaste decennierna kompletterats medmjölkningsrobotar. Alla kor i en besättning ges en egen unik identitet iform av RFID-chip. Detta innebär att man i en modern mjölkanläggningkan få exakta uppgifter ang varje kos produktionskapacitet, dvs levereradmjölkmängd i förhållande till förbrukat foder. Utvecklingen har såledesgått långt när det gäller kontroll av kvaliten för den mjölk somproduceras. För att bibehålla en hög kvalite'på den producerade mjölkenbehöver den dels kylas från spenvarm till en lagringstemperatur på ca +3°C.A traditional staple food is milk from grazing and ruminant animals. Animal husbandry with free-ranging herds in open animal sheds and open landscapes has been supplemented with milking robots in recent decades. All cows in a herd are given their own unique identity in the form of an RFID chip. This means that in a modern dairy farm you can get exact information about each cow's production capacity, i.e. the amount of milk delivered in relation to the feed consumed. The development has thus come a long way when it comes to quality control for the milk that is produced. In order to maintain a high quality of the milk produced, it needs to be cooled from teat warm to a storage temperature of approx. +3°C.
Mj ölken måste även kunna förvaras vid lämpliga och låga temperatuerbåde fram till transport till mejeri, men framför allt under tiden fyllningav en samlingstank pågår och som inteimittent matas med spenvarmmjölk från mjölkningsrobotarna.The beer must also be able to be stored at suitable and low temperatures both until transport to the dairy, but above all during the time a collection tank is being filled and which is not immediately fed with teat-warm milk from the milking robots.
Huvudsyftet med föreliggande uppfinning är att skapa förutsättningar föroch genomföra en effektiv kylning i en samlingstank hos en modemmjölkproducent.The main purpose of the present invention is to create conditions for and implement effective cooling in a collection tank at a modern milk producer.
Syftet med uppfinningen uppnås genom att förfarandet ocharrangemanget för värmeväxling erhållit de i patentkraven angivnakännetecknen.The purpose of the invention is achieved by the method and the arrangement for heat exchange obtaining the characteristics specified in the patent claims.
Genom att köldmediet matas i ett kanalsystem som är uppdelat iåtminstone en förgreningszon, från vilken/vilka flera separata delkanalerutgår och vidare i ett fördelande, snirklande förlopp för uppsamling iåtminstone en uppsamlingszon. lkyflarrzlngeiiiaiiget iiigåif således en konipressor, en leondeiisor/gaskyflare,en expansionsenliet, en *íïširåiigzlre (integrerad i sarnlingstaiiktzlnli). enxfätslieayfskllljare, sanit en 'vfärmevä.xlare. Köldiiiediet passerar dessaenheter i nämnd turordning och sedan tillbaka till kopressern i ett sliitetsystern. Därmed skapas en högeffektiv kylning av mjölken i ensamlingstank.By feeding the refrigerant in a channel system which is divided into at least one branching zone, from which/which several separate sub-channels emanate and further in a distributing, winding process for collection in at least one collection zone. The lkyflarrzlngeiiiaiiget iiigåif thus a conipressor, a leondeiisor/gaskyflare, an expansion senliet, a *íïširåiigzlre (integrated in the sarnlingstaiiktzlnli). enxfätslieayfskllljare, sanit a 'vfarmer.xler. The cold feed passes through these units in the order mentioned and then back to the co-compressor in a solid state. This creates a highly efficient cooling of the milk in a single collection tank.
I det följ ande kommer uppfinningen att beskrivas i anslutning tillkvalitetsskonsam kylning av mjölk i en samlingstank under hänvisningtill ett på följ ande ritningsblad visat utföringsexempel, där Fig. l är en schematisk vy över en anläggning för hantering och lagringav mjölk vid en modem ladugärd med frigäende kor Fig. 2 är en schematisk vy av ett kanalsystem ingäende i ettkylarrangemang i enlighet med föreliggsnde uppfinning, Fig. 2a är en delförstoming av en förgreningsdel vid kanalsystemet enligtfig. 2, och där Fig. 2b är en delförstoring av en samlingsdel vid kanalsystemet enligt fig.Fig. l visar en schematiska vyn över en känd anläggning för hanteringoch lagring av mjölk vid en modem ladugärd med frigäende kor. Härframgär de temperatur- och trycksensorer och pumpar som finnsplacerade i anläggningen samt de olika kärlen för uppsamling,mellanlagring och slutlagring av mjölken. Slutlagringen pä gärden sker ien större samlingstank, frän vilken mjölken förs över till en tankbil förtransport till mejeriet.In the following, the invention will be described in connection with quality-friendly cooling of milk in a collection tank with reference to an embodiment shown on the following drawing sheet, where Fig. 1 is a schematic view of a facility for handling and storing milk in a modern barn with free cows Fig. 2 is a schematic view of a duct system included in a cooling arrangement in accordance with the present invention, Fig. 2a is a partial schematic of a branching part of the duct system according to fig. 2, and where Fig. 2b is a partial enlargement of a collection part at the channel system according to Fig. 1 shows a schematic view of a known facility for the handling and storage of milk at a modem barnyard with loose cows. The temperature and pressure sensors and pumps located in the facility as well as the various vessels for collection, intermediate storage and final storage of the milk make this clear. The final storage on the farm takes place in a larger collection tank, from which the milk is transferred to a tank truck for transport to the dairy.
I den i fig. 2 visade schematiska vy av ett kanalsystem ingäende i ettkylarrangemang framgär hur köldmediet, i detta fall CO2 vid mättligt lägtemperatur, fördelas i flera delkanaler (fig. 2a) för att efter passage genomdelkanalema samlas upp (fig. 2b) för vidare förängning ochätercirkulation enligt schema och turordning ovan.In the one in fig. 2 showed a schematic view of a channel system included in a cooling arrangement showing how the refrigerant, in this case CO2 at a saturated room temperature, is distributed in several partial channels (fig. 2a) so that after passing through the partial channels it is collected (fig. 2b) for further expansion and recirculation according to the scheme and turn order above.
Det är säledes av största vikt att mjölkens fetter inte päverkas negativtunder hanteringen pä gärden, vilket riskerar att ske om mjölken kyles nedtill ca + 2°C grader.It is therefore of the utmost importance that the milk's fats are not negatively affected during handling on the farm, which risks happening if the milk is cooled below approx. + 2°C degrees.
I samlingstanken finns omrörare anordnade för att skapa flöden avintennittent inmatad spenvarrn mjölk förbi kylande delytor isamlingstankens inre.In the collection tank, agitators are arranged to create the flow of intentionally fed weaned milk past the cooling surface of the interior of the collection tank.
. Mjölken i samlingstanken kommer att hämtas upp av en tankbil somunder sommartid normalt saknar kylkapacitet under transporten tillmejeriet. Under vintertid gäller det att mjölken inte fär kylas av lägayttertemperaturer, utan skall, sä längt möjligt hällas vid max + 3°C.. The milk in the collection tank will be picked up by a tanker which, during the summer, normally lacks cooling capacity during transport to the dairy. During winter, the milk must not be cooled by outside temperatures, but must, as far as possible, be poured at a maximum of + 3°C.
Detta innebär att tankbilsföraren sj älv mäste avgöra om han eller hon,beroende pä väder och yttertemperatur, och med vetskap omtemperaturen pä en redan insamlad mjölkvolym, kan fylla pä ytterligaremjölkvolymer med tveksamma temperaturer under rädandeomständigheter.This means that the tanker driver himself must decide whether he or she, depending on the weather and outside temperature, and knowing the temperature of an already collected volume of milk, can fill in additional milk volumes with questionable temperatures under rescue circumstances.
I dag förekommer det att all mjölk i en tankbil mäste kasseras dä mjölkenutsatts för icke tillåtna temperaturer, vilket innebär för hög temperatur päsommaren och för läg temperatur pä vintem.Today, it happens that all the milk in a tank truck must be discarded because the milk has been exposed to impermissible temperatures, which means too high a temperature in the summer and too low a temperature in the winter.
Uppfinningen är inte begränsad till det ovan beskrivna utföringsexempletutan modifikationer kan ske inom ramen för de nedan angivnapatentkravenThe invention is not limited to the exemplary embodiment described above, but modifications can take place within the scope of the patent claims stated below
