Description
i 148912in 148912
Opfindelsen angår en fremgangsmåde til fremstilling af et kaffep.rodukt bestående af fritstrømmende agglome-rater, som omfatter partikler af opløselig kaffe og finmalet ristet kaffe, idet den finmalede ristede kaffe er til stede i en mængde på 2 - 20 vægtpct. beregnet på vægten af de to kaffebestanddele og har en sådan partikelstørrelse, at 90 vægtpct. af den formalede kaffe passerer en sigte med maskevidde 75 ^urn. Ved denne fremgangsmåde formes ristet kaffe i meget finformalet partikelform sammen med opløselig kaffe til koagglomererede granuler, i det følgende betegnet agglomerater.The invention relates to a process for preparing a coffee product consisting of free flowing agglomerates comprising soluble coffee particles and finely ground roasted coffee, the finely ground roasted coffee being present in an amount of 2 to 20% by weight. calculated on the weight of the two coffee ingredients and having such a particle size that 90% by weight. of the ground coffee, a sieve of mesh width passes 75 ^ urn. In this process, roasted coffee is formed into very fine-grained particulate form together with soluble coffee for coagglomerated granules, hereinafter referred to as agglomerates.
Der har fra tid til anden været interesse for blandinger af opløselig kaffe med forskellige procentmængder, sædvanligvis mindre end 15 vægtpct. finmalet ristet kaffe. Sådanne blandinger har den fordel, at de inkorporerer aromatiske duftelementer i ristet kaffe, som det ikke er let at opnå i den opløselige kaffedel, især når den fremstilles ved en konventionel sprøjtetørringsmetode. Sådanne blandinger er fra tid til anden blevet solgt kommercielt, men det har været blandinger af opløseligt kaffepulver og ristede og formalede partikler, som, selv om de blandes homogent, giver meget ringe strømningsevne og er vanskelige at hælde op med ske.From time to time, there has been interest in mixtures of soluble coffee with different percentages, usually less than 15% by weight. finely ground roasted coffee. Such blends have the advantage of incorporating aromatic fragrance elements into roasted coffee which is not readily obtainable in the soluble coffee portion, especially when prepared by a conventional spray drying method. Such mixtures have been sold commercially from time to time, but they have been mixtures of soluble coffee powder and roasted and ground particles which, although mixed homogeneously, give very poor flowability and are difficult to pour with spoon.
Endvidere er sådanne produkter sammensat af ristede og formalede partikler, som har tendens til at udfældes i færdigbrygget kaffe med mælk og/eller vand og danne en uønsket mængde grums, hvilket virker negativt på forbrugeren. Nogle mængder grums som i hjemmebrygget 100¾ ristet og formalet kaffe er imidlertid acceptabelt for forbrugeren, og faktisk er en vis uklarhed af sådanne produkter i koppen ønskelig.Furthermore, such products are composed of roasted and ground particles, which tend to precipitate into brewed coffee with milk and / or water and produce an undesirable amount of grime, which adversely affects the consumer. However, some quantities of grums such as in the home-brewed 100¾ roasted and ground coffee are acceptable to the consumer, and in fact some obscurity of such products in the cup is desirable.
Det har vist sig, at der kan opnås et tiltalende kaffeprodukt, hvis opløselig kaffe og finmalet ristet kaffe 148912 2 kombineres til agglomerater, f.eks. ved kendte agglomere-ringsmetoder. Imidlertid har man nu fundet, at der ved en særlig udformning af formalingsprocessen for den ristede kaffe kan opnås et mere acceptabelt kaffeprodukt, som er letstrømmende og bevarer i det væsentlige alle de oprindelige aromaelementer i den ristede formalede kaffe, og som giver minimal sedimentering i den færdige drik.It has been found that an attractive coffee product can be obtained if soluble coffee and finely ground roasted coffee are combined into agglomerates, e.g. by known agglomeration methods. However, it has now been found that by a particular design of the grinding process for the roasted coffee, a more acceptable coffee product can be obtained which is light flowing and retains substantially all of the original aroma elements of the roasted ground coffee and which provides minimal sedimentation in the roasted coffee. ready beverage.
Tør formaling af ristede kaffebønner til relativt groft pulver er en velkendt operation indenfor kaffeindustrien.Dry grinding of roasted coffee beans into relatively coarse powder is a well-known operation in the coffee industry.
Der findes forskellige beskrivelser af finmaling af ristet kaffe under bevarelse af dens aromatiske karakter ved anvendelse af en kryogen formalingsteknik omfattende et enkelt trin. Ved en sådan metode afkøles de ristede kaffebønner før formalingen til temperaturer under 10°C, f.eks. som beskrevet i U5 patentskrift nr. 3 261 689.There are various descriptions of finely ground coffee roasting while preserving its aromatic character using a single step cryogenic technique. In such a method, the roasted coffee beans are cooled before grinding to temperatures below 10 ° C, e.g. as described in U5 Patent No. 3,261,689.
Alternativt er det blevet foreslået at indføre flydende nitrogen i en kværn under formalingen af ristede kaffebønner, som beskrevet i Food Engineering, May 1962, side 62 og 63. Andre metoder til formaling af ristede kaffebønner er beskrevet i GB patentskrifterne nr.Alternatively, it has been proposed to introduce liquid nitrogen into a grinder during the grinding of roasted coffee beans, as described in Food Engineering, May 1962, pages 62 and 63. Other methods for grinding roasted coffee beans are described in GB Patent Specification no.
1 424 264 og 1 476 854. Disse metoder giver imidlertid stadig kun relativt fint pulver og fører i almindelighed ikke til den mest ønskede gennemsnitlige partikel-størrelse på ned til 20 ^um eller mindre. Det kan bemærkes, at ifølge US patentskrift nr. 3 261 689 passerede kun 50% af den formalede kaffe igennem en 200 U.S. mesh screen (dvs. maskevidde 74 ^um), og ifølge GB patentskrift nr. 1 476 854 var den formalede kaffe ikke finere end 70 mesh (dvs. maskevidde 210 yUm). Det vil også bemærkes, at den almene procedure i de tidligere patent-skrifter er at suspendere sådanne formalede produkter i flydende kaffeekstrakt og derpå sprøjtetørre; dette sprøjtetørringstrin fører uundgåeligt til tabet af 148912 3 flygtige komponenter, og der fremstilles også produkter, som har nogle problemer med strømningsevnen.1 424 264 and 1 476 854. However, these methods still provide only relatively fine powder and generally do not result in the most desired average particle size of down to 20 µm or less. It should be noted that according to U.S. Patent No. 3,261,689, only 50% of the ground coffee passed through a 200 U.S.C. mesh screen (i.e., mesh size 74 µm), and according to GB Patent No. 1,476,854, the ground coffee was no finer than 70 mesh (i.e. mesh size 210 µm). It will also be noted that the general procedure of the prior patent applications is to suspend such milled products in liquid coffee extract and then spray dry; this spray drying step inevitably leads to the loss of volatile components, and products which have some flowability problems are also produced.
De ovennævnte tidligere forslag har ikke givet et ristet kaffeprodukt med tilstrækkelig fin størrelse eller en fremgangsmåde til fremstilling af et sådant produkt blandet med konventionel opløselig kaffe på en sådan måde, at der fås et fritstrømmende og aromaholdigt produkt.The aforementioned previous proposals have not provided a roasted coffee product of sufficiently fine size or a method of making such a product blended with conventional soluble coffee in such a way as to obtain a free flowing and aromatic product.
Dette opnås ved fremgangsmåden ifølge opfindelsen, som er ejendommelig ved, at findelingen af ristede kaffebønner udføres ved en knusemetode, som indebærer en forhåndsafkøling af de ristede kaffebønner til under 0°C, fortrinsvis til under -45°C, kombineret mød en efterfølgende luftsigtning af den finmalede ristede kaffe under anvendelse af afkølet luft i sigtetrinnet, idet forhånds-afkølingen udføres med flydende nitrogen, således at de afkølede gasser i sigtetrinnet inkluderer nitrogen og luft i blanding, og at de finmalede ristede kaffebønner blandes med opløseligt kaffepulver, og blandingen derefter damp-agglomereres.This is achieved by the method according to the invention, which is characterized in that the comminution of roasted coffee beans is carried out by a crushing method which involves pre-cooling the roasted coffee beans to below 0 ° C, preferably to below -45 ° C, combined with a subsequent air screening of the finely ground roasted coffee using cooled air in the sieving step, the pre-cooling being carried out with liquid nitrogen so that the cooled gases in the sieving stage include nitrogen and air in admixture, and the finely ground roasted coffee beans are mixed with soluble coffee powder, and then the steam is mixed -agglomereres.
Fortrinsvis findeles den ristede kaffe til en partikelstørrelse på under 50 ^um, og fortrinsvis til en sådan partikelstørrelse, at 90¾ af den formalede kaffe passerer en sigte med maskevidde 25 ^um. Det mest foretrukne er, at den ristede kaffe findeles til en sådan partikelstørrelse, at i hovedsagen al kaffen har en partikelstørrelse på mellem 5 og 20 ^um. Anvendelse af finmalet ristet kaffe med en partikelstørrelse i den nedre ende af de ovenfor angivne størrelsesområder frembringer minimal sedimentering, når agglomerater fremstillet af en sådan kaffebestanddel laves til en drik.Preferably, the roasted coffee is comminuted to a particle size of less than 50 µm, and preferably to such a particle size that 90¾ of the ground coffee passes a mesh of 25 µm mesh. The most preferred is that the roasted coffee is comminuted to such a particle size that substantially all the coffee has a particle size of between 5 and 20 µm. Use of finely ground roasted coffee with a particle size at the lower end of the size ranges listed above produces minimal sedimentation when agglomerates made from such a coffee ingredient are made into a beverage.
4 1489124 148912
Findelingen af de ristede kaffebønner kan frembringes ved anvendelse af en slagmølle forsynet med organer til luftsigtning, som kun tillader formalet kaffe i den ønskede partikelstørrelse at forlade møllen som produkt. Imidlertid kan luftsigtningssystemet være uden for møllen, blot der sørges for tilbageføring af den grovere fraktion til møllen. Andre midler til opnåelse af den ønskede partikelstørrelse af finmalet ristet kaffe med acceptabelt minimalt tab af flygtige komponenter kan anvendes. Selv om det ikke foretrækkes, kan en formalingsmetode uden anvendelse af flydende kølemiddel anvendes til at give den finmalede ristede kaffe.The comminution of the roasted coffee beans can be accomplished by using an impact grinder provided with air sieving means which allows only ground coffee of the desired particle size to leave the mill as a product. However, the air screening system may be outside the mill provided that the coarser fraction is returned to the mill. Other means for obtaining the desired particle size of finely ground roasted coffee with acceptable minimal loss of volatile components may be used. Although not preferred, a grinding method without the use of liquid refrigerant can be used to provide the finely ground roasted coffee.
I overensstemmelse med opfindelsen formes den finmalede ristede kaffe til agglomerater med opløselig kaffe, og den opløselige kaffe er fortrinsvis en, som en gennemsnitlig partikelstørrelse på mindre end 50 ^um. De to kaffebestanddele vil blandes til dannelse af en i det væsentlige homogen blanding og derefter koagglomereres til dannelse af agglomeraterne ifølge opfindelsen. Agglo-mereringen kan frembringes på en lang række forskellige måder, men frembringes fortrinsvis ved anvendelse af de procedurer, som er beskrevet i GB patentskrift nr.In accordance with the invention, the finely ground roasted coffee is formed into soluble coffee agglomerates, and the soluble coffee is preferably one, which has an average particle size of less than 50 µm. The two coffee ingredients will be blended to form a substantially homogeneous blend and then coagglomerated to form the inventive agglomerates. The agglomeration can be produced in a wide variety of ways, but is preferably produced using the procedures described in GB patent no.
1 224 807, hvilket patentskrift også beskriver den forudgående formaling af den opløselige kaffe, som er et ønskeligt trin ved den foreliggende opfindelse.No. 1,224,807, which also discloses the prior milling of the soluble coffee, which is a desirable step of the present invention.
Agglomeraterne som fremstilles ifølge opfindelsen, kan indeholde 5-20 vægtpct. af den ristede og finmalede kaffe, og fortrinsvis 8-12 vægtpct. Om ønsket kan en del af den indeholdte kaffeolie fjernes fra den finmalede ristede kaffe før formalingstrinnet, som går forud for dannelsen af agglomeraterne ifølge opfindelsen; teknik til udførelse af dette er velkendt for fagfolk.The agglomerates prepared according to the invention may contain 5-20% by weight. of the roasted and finely ground coffee, and preferably 8-12% by weight. If desired, a portion of the coffee oil contained may be removed from the finely ground roasted coffee prior to the grinding step preceding the formation of the inventive agglomerates; The technique for performing this is well known to those skilled in the art.

Fortrinsvis har agglomeraterne, som fremstilles ifølge opfindelsen, en gennemsnitlig partikelstørrelse på over 850 ^um og helst mellem 1200 og 2400 ^um.Preferably, the agglomerates prepared according to the invention have an average particle size of over 850 µm and most preferably between 1200 and 2400 µm.
Fremgangsmåden ifølge opfindelsen belyses nærmere ved de efterfølgende eksempler.The process according to the invention is further illustrated by the following examples.
EKSEMPEL 1 20 kg af en ristet kaffeblanding (Colombia/Santos) blev neddyppet i flydende nitrogen i et kort tidsrum og derefter kørt gennem en slaghammermølle udstyret med en indvendig luftsigte. Formalingen blev udført med flydende nitrogen som blev indført både til malekammeret og til luftsigtestrømmen. Temperaturen af den udstrømmende luft blev noteret til -45 °C. Brugen af det flydende nitrogen hjalp til ved finmalingen af kaffen, da det har en sprødgørende virkning på kaffen. Partikelstørrelsesmålingen af det formalede produkt blev udført ved hjælp af en luftsigte af typen "Coulter Counter". 98 % af produktet, efter vægt, havde en partikelstørrelsesdiameter på under 32 yum, og 91 vægtpct. havde en partikelstørrelsesdiameter på under 25 ^urn. 80 % af produktet, efter vægt, havde en partikelstørrelse mellem 5 og 25 ^um.EXAMPLE 1 20 kg of a roasted coffee blend (Colombia / Santos) was immersed in liquid nitrogen for a short period of time and then run through a hammer mill equipped with an internal air sieve. The milling was carried out with liquid nitrogen which was introduced both to the grinding chamber and to the air sieve stream. The temperature of the outflowing air was noted at -45 ° C. The use of liquid nitrogen helped in the grinding of the coffee as it has a crushing effect on the coffee. The particle size measurement of the milled product was performed using a "Coulter Counter" air screen. 98% of the product, by weight, had a particle size diameter of less than 32 µm and 91% by weight. had a particle size diameter of less than 25 µm. 80% of the product, by weight, had a particle size between 5 and 25 µm.
18 kg af den resulterende finmalede kaffe blev så blandet med 162 kg af et opløseligt kaffepulver, som var fremstillet på konventionel made i et ekstraktionsbatteri, ud fra ristet kaffe og ved forstøvningstørring hvor der blev anvendt temperaturer pa 220 °C (indløb) og 100 °C (udløb). Blandingen af formalet og opløselig kaffe blev madet gennem en vertikal kuglemølle, hvor partikelstørrelsen af bestanddelen af forstøvningstørret 6 148912 pulver blev reduceret til under 50 yum. Blandingen af fint pulver blev så agglomereret til granulat på den måde, som er beskrevet i britisk patentskrift nr. 1 224 807. De grove agglomerater blev afkølet og sigtet så man fik slutproduktet med den nødvendige partikel-størrelse. Materialet, som var for småt, blev recirkuleret som også beskrevet.18 kg of the resultant finely ground coffee was then mixed with 162 kg of a soluble coffee powder, prepared in a conventional manner in an extraction battery, from roasted coffee and by spray drying using temperatures of 220 ° C (inlet) and 100 °. C (outlet). The mixture of ground and soluble coffee was fed through a vertical ball mill, where the particle size of the component of spray-dried powder was reduced to below 50 µm. The fine powder mixture was then agglomerated to granulate in the manner described in British Patent Specification No. 1,224,807. The coarse agglomerates were cooled and sieved to give the final product of the required particle size. The material which was too small was recycled as also described.
65 % af det færdige agglomererede produkt havde granule-størrelser på over 850 ^um, mens 50 % havde granulestør-relser mellem 1200 og 2400 ^um, efter vægt.65% of the finished agglomerated product had granule sizes over 850 µm, while 50% had granule sizes between 1200 and 2400 µm, by weight.
Efter tillavning med varmt vand blev produktet sammenlignet som drik med den samme forstøvningstørrede og opløselige kaffe alene. Det viste øget aromatisk anslag med forbedret aroma og udseende i koppen (turbiditet).After cooking with hot water, the product was compared as a drink with the same spray-dried and soluble coffee alone. It showed increased aromatic impact with improved aroma and appearance in the cup (turbidity).
Granulatet havde også en stor strømningsevne og kunne let tages ud med ske.The granulate also had a great flowability and could easily be taken out with spoon.
EKSEMPEL 2 18 kg af en ristet kaffeblanding (Colombia/Santos) blev kørt gennem en slagstift/skivemølle med høj hastighed og med kontraroterende skiver. Flydende nitrogen blev indført på 2 punkter i skruesystemet, som madede møllen, og temperaturen i malekammeret blev registreret som -50 °C. Mere end 99 % af produktet, efter vægt, havde en partikelstørrelse på under 63 yum, og 97 vægtpct. var under 40 ^um i partikelstørrelse. Den gennemsnitlige partikelstørrelse blev fundet at være mellem 10 og 20 yum. Partikelstørrelsesmålinger blev foretaget ved konventionel sigteanalyse, idet der også blev brugt luftstråleklaringsudstyr i de anvendte sigter.EXAMPLE 2 18 kg of a roasted coffee blend (Colombia / Santos) was run through a high speed impact pin / disc grinder with counter-rotating slices. Liquid nitrogen was introduced at 2 points in the screw system which fed the mill and the temperature in the grinding chamber was recorded as -50 ° C. More than 99% of the product, by weight, had a particle size of less than 63 µm and 97% by weight. was below 40 µm in particle size. The average particle size was found to be between 10 and 20 µm. Particle size measurements were made by conventional sieve analysis, using air jet clearing equipment in the sieves used.
