Description

Fremgangsmåte til findeling resp. maling av kornede nærings-eller nydelsesmidler, særlig brente kaffebønner. Procedure for fine division or grinding of grainy food or pleasure products, especially roasted coffee beans.

Ved maling av brente kaffebønner opp-står, særlig ved den for oppnåelse av bedre utlutning tilstrebede finmaling, en sådan oppvarmning av kvernen og malegodset, at kaffebønnenes oljeinnhold blander seg pastaaktig med kaffemelet, hvorved, når den malte kaffe overheldes med varmt eller kokende vann, mengden av de av kaffemelet uttrukne stoffer blir redusert og kaffens smak og kvalitet nedsatt. Det oljeinnhold, som under malingen på grunn av oppvarmningen mister sin tetthet, utsettes ved påvirkning av luft og dennes surstoff for en oksydasjon og såvel kvalitets- som smaksforringelse. For kaffe resp. annet malegods er det riktignok kjent å benytte vannkjølte kverner med vannsirkulasjon i hule vegger. Ved disse kverner foregår imidlertid malingen ikke i lukkede rum uten tilgang av friskluft eller surstoff, så at oljeinnholdet i malegodset alltid får den uheldige påvirkning og aromaen blir bety-delig svekket resp. forsvinner helt. When grinding roasted coffee beans, particularly in the case of fine grinding aimed at achieving better leaching, such heating of the grinder and the grinding material occurs that the oil content of the coffee beans mixes like a paste with the coffee flour, whereby, when the ground coffee is poured over with hot or boiling water, the quantity of substances extracted from the coffee flour is reduced and the taste and quality of the coffee reduced. The oil content, which loses its density during painting due to the heating, is exposed to oxidation and both quality and taste deterioration when exposed to air and its oxygen. For coffee or other grinding goods, it is admittedly known to use water-cooled mills with water circulation in hollow walls. At these mills, however, the grinding does not take place in closed rooms without access to fresh air or oxygen, so that the oil content in the grinding material is always adversely affected and the aroma is significantly weakened or disappears completely.

Foreliggende oppfinnelse angår en The present invention relates to a

fremgangsmåte til findeling resp. maling av kornede nærings- eller nydelsesmidler med fett- eller oljeinnhold, særlig brente kaffebønner, i med kjøleinnretninger forsynte findelings- resp. maleinnretninger og i en atmosfære av en inaktiv gass, særlig kullsyre. procedure for fine division or grinding of grainy foodstuffs or pleasure products with fat or oil content, especially roasted coffee beans, in shredding resp. grinding devices and in an atmosphere of an inert gas, especially carbonic acid.

Det er kjent å dypkjøle til -=- 70° C. Deep cooling to -=- 70° C is known.

Dette er imidlertid uøkonomisk og ved kaffe aromaskadelig. Oppfinnelsen karakteri-seres ved at under trykk stående kullsyre ledes inn i malerommet, hvor den under sin ekspansjon trykker luften ut fra samme og ledes mot maleorganene, hvorved det foruten en beskyttelse av malegodset mot luftens surstoff også oppnåes en dypkjøling av malerummet til en temperatur mellom 0° C og -f- 15° C. Dypkjølingen av malegodset og de av dette passerte kammere skjer ved hjelp av i rørledninger tilført og gjennom utløpsdyser utsprøytet kullsyre, idet den av den utsprøytede kullsyre fortrengte luft fjernes fra kammeret gjennom anordninger i kammerveggen, som kun til-later utstrømning. Den med høyt trykk i kammeret innsprøytede kullsyre blir også rettet mot de malende deler av findelings-eller maleinnretningen og mot det malegods, som passerer disse deler, slik at den under malingen ved friksjon oppstående varme blir helt uskadeliggjort. Den til ut-førelse av fremgangsmåten tjenende findelings- og maleinnretning er utrustet med et lufttett, lukket malekammer, som er forsynt med midler til dypkjøling med indifferente, ekspanderende gasser, som ikke inneholder surstoff. However, this is uneconomical and, in the case of coffee, harmful to the aroma. The invention is characterized by the fact that pressurized carbon dioxide is led into the grinding chamber, where during its expansion it pushes the air out of it and is directed towards the grinding organs, whereby in addition to protecting the grinding material against the oxygen in the air, a deep cooling of the grinding chamber to a temperature between 0° C and -f- 15° C. The deep-cooling of the ground material and the chambers it passes through takes place with the help of carbonic acid supplied in pipelines and sprayed through outlet nozzles, the air displaced by the sprayed carbonic acid being removed from the chamber through devices in the chamber wall, which only allows outflow. The carbonic acid injected at high pressure into the chamber is also directed at the grinding parts of the shredding or grinding device and at the grinding material that passes these parts, so that the heat generated by friction during grinding is completely neutralized. The comminution and grinding device used to carry out the method is equipped with an airtight, closed grinding chamber, which is provided with means for deep cooling with inert, expanding gases, which do not contain oxygen.

Andre detaljer ved oppfinnelsen er nærmere beskrevet i beskrivelsen under henvisning til tegningen, som viser et ek-sempel på en anordning til utførelse av fremgangsmåten ifølge oppfinnelsen. Other details of the invention are described in more detail in the description with reference to the drawing, which shows an example of a device for carrying out the method according to the invention.

Fig. 2 viser en del av beholderen i hori-sontalsnitt resp. sett ovenfra mot den ho-risontale skillevegg. Fig. 2 shows part of the container in horizontal section or seen from above towards the horizontal partition.

Med 1 er betegnet den lukkede f orråds-beholder for malegodset, f. eks. brente kaf-febønner, hvilken beholder har en ved hjelp av en klaff 2 stengbar fylleåpning samt en bunn 3 med ved hjelp av et dreie-spjeld 16 regulerbare tømmeåpninger 4. Derunder befinner seg et lukket tilførings-kammer 5 med maleinnretning i form av en fortannet malekjegle 6 på en aksel 7 og en likeledes fortannet, malekjeglen omslut-tende gjennomløpsåpning 8 i forrådsbe-holderens bunnstuss 9. Det malte gods kommer ned i et traktformig innsnevret oppfangningskammer 10 med utløpsåpning 11, fra hvilken det malte gods faller ned i et derunder værende lukket kammer 12, inne i hvilket det fylles i til paknings- og oppfangningsbeholdere svarende småbe-holdere, som derpå lukkes ved hjelp av ikke viste innretninger. I mellemkammeret resp. tilføringskammeret 5 for malegodset inn-føres rørledninger 13, 14 med utløpsdyser 15 for den med høyt trykk utsprøytede indifferente gass. Den ved utsprøytningen under høyt trykk av den indifferente gass tilveiebragte dypkjøling brer seg ved hen-siktsmessig anordning av dysene 15 over hele kammeret 5 og det deri værende malegods. Som indifferent gass anvendes for-trinnsvis kullsyre. Man kan også benytte kvelstoff. Rørledningenes 13, 14 ender er forsynt med tilsvarende utløpsdyser 15, og disse er rettet direkte mot deler av maleinnretningen 6, 8 og 9 for at også disse skal bli utsatt for en direkte kjølevirkning. Det tilsluttede oppfangningskammer 10 og det derunder værende overfyllingskammer 12 for malegodset kan likeledes være fylt med resp. gjennom maleinnretningen 6 til 9 holdes stadig tilført indifferent gass, som ved trykkstigning og utsprøytning frem-bringer dypkjøling. Ved stadig ny tilførsel av dypkjølende, indifferent gass som f. eks. kullsyre og kvelstoff kan fjernelsen av den fortrengte luft skje gjennom i kammerveg-gene anordnede tilbakeslagsventiler, som kun åpner seg utad. I forrådsbeholderen 1 kan luften også av den nedenfra fra kammeret oppstigende, dypkjølende, indifferente gass fortrenges oppover gjennem malegodset. 1 denotes the closed supply container for the paint material, e.g. roasted coffee beans, which container has a filling opening that can be closed by means of a flap 2 and a bottom 3 with emptying openings 4 that can be regulated by means of a rotary damper 16. Underneath is a closed supply chamber 5 with a grinding device in the form of a toothed grinding cone 6 on a shaft 7 and a likewise toothed, through-opening 8 enclosing the grinding cone in the supply container's bottom connection 9. The ground material descends into a funnel-shaped, narrowed collection chamber 10 with an outlet opening 11, from which the ground material falls into a below closed chamber 12, inside which small containers corresponding to packing and collection containers are filled, which are then closed using devices not shown. In the middle chamber or pipelines 13, 14 with outlet nozzles 15 for the high-pressure sprayed inert gas are introduced into the supply chamber 5 for the grinding material. The deep cooling provided by the spraying under high pressure of the inert gas spreads through the appropriate arrangement of the nozzles 15 over the entire chamber 5 and the material to be ground therein. Carbonic acid is preferably used as the inert gas. Nitrogen can also be used. The ends of the pipelines 13, 14 are provided with corresponding outlet nozzles 15, and these are directed directly at parts of the grinding device 6, 8 and 9 so that these too are exposed to a direct cooling effect. The connected collection chamber 10 and the below overflow chamber 12 for the paint material can also be filled with resp. through the grinding device 6 to 9, inert gas is continuously supplied, which, when the pressure rises and is sprayed, produces deep cooling. With constant new supply of deep-cooling, inert gas such as e.g. carbon dioxide and nitrogen, the removal of the displaced air can take place through non-return valves arranged in the chamber walls, which only open outwards. In the storage container 1, the air can also be displaced by the deep-cooling, indifferent gas rising from below from the chamber upwards through the grinding material.
