Description

Anordning til fremstilling av yoghurt og andre ved termobakterier dannede kulturmelkesorter i husholdningen. Device for the production of yoghurt and other cultured milks produced by thermobacteria in the household.

Ved de kjente fremgangsmåter til kon-tinuerlig gjæring av melk i husholdninger By the known methods for continuous fermentation of milk in households

gjør man bruk av en hengende gjærbærer, if you use a hanging yeast carrier,

som henges ned i den melk som skal gjæres, which is suspended in the milk to be fermented,

eller man bruker et gjærinneholdende kar or you use a vessel containing yeast

med vannfylling, som blir satt ned i melken, with water filling, which is put into the milk,

og som både besørger gjæringen av melken and which both ensure the fermentation of the milk

(det dreier seg alltid om kokt, meget varm (it always refers to cooked, very hot

melk) og avkjølingen til passende temperatur. milk) and the cooling to the appropriate temperature.

Sistnevnte fremgangsmåte har den for-del at man ikke behøver å vente på utjev-ningen av temperaturen, mens ved bruken The latter method has the advantage that you do not have to wait for the temperature to equalize while using it

av den hengende gjærbærer (gjærbærende of the hanging yeast carrier (yeast carrier

kar) kan avkjølingen skje ved en åpen vessel) the cooling can take place by an open

vannbeholder, i hvilken den varme melk water container, in which it heats milk

settes ned, og hvis vann stadig fornyes. is set down, and whose water is constantly renewed.

Denne kjente fremgangsmåte har også This known method also has

sine svakheter, da det gjærbærende kar, its weaknesses, when the yeast-bearing vessel,

som settes ned i melken, er meget vo-luminøst (omkring halvparten av melkekarets volum), og må ved nedsettelsen i which is put down in the milk, is very voluminous (about half the volume of the milk container), and must be put down in

melken holdes ved en finger i en løkke festet the milk is held by a finger in a loop attached

i dets overkant, hvorved oppstår infek-sjonsfare. in excess of that, whereby there is a risk of infection.

De nevnte svakheter ved de tidligere They mentioned weaknesses of the former

fremgangsmåter ble søkt avhjulpet på to procedures were sought to be remedied in two

måter. ways.

Den ene bestod deri, at man brukte en One consisted in using one

vannfyldt, forholdsvis liten kule som gjærbærer, som blev sluppet fritt fallende ned i water-filled, relatively small sphere like a yeast carrier, which was released free-falling into it

melken og sank ned på melkekarets bunn, the milk and sank to the bottom of the milk vessel,

som omkring denne del var omgitt av koldt which around this part was surrounded by cold

vann. water.

Dette har den svakhet at den tynn-veggede kule lett ble sprengt istykker, og at This has the weakness that the thin-walled bullet was easily blown to pieces, and that

det omgivende vann var vanskelig å av-stenge fullstendig. the surrounding water was difficult to shut off completely.

Denne metode hadde også andre svakheter, idet vekslingen i den yttre lufttempe-ratur efter de vekslende årstider og vær-forhold, snart førte til for hurtig kjøling av den gjærende melk og snart til at den holdt for høy temperatur. This method also had other weaknesses, as the change in the external air temperature according to the changing seasons and weather conditions soon led to too rapid cooling of the fermenting milk and soon to it maintaining too high a temperature.

Alle forannevnte metoder og anord-ninger hadde imidlertid også den svakhet at man i hovedsaken bare kunne videredyrke bacillus bulgarius i høy renhetsgrad, og ikke den aromatiske streptococcus thermophilus, som i den bedre sort av yoghurt opptrer sammen med bacillus bulgarius. However, all of the aforementioned methods and devices also had the weakness that, in the main, you could only further cultivate bacillus bulgarius in a high degree of purity, and not the aromatic streptococcus thermophilus, which in the better variety of yogurt appears together with bacillus bulgarius.

I henhold til foreliggende oppfinnelse er det nå mulig å videredyrke i høy renhetsgrad også streptococcus thermophilus og andre melkesyrebakterier av samme art. According to the present invention, it is now possible to further cultivate streptococcus thermophilus and other lactic acid bacteria of the same species in a high degree of purity.

Ifølge oppfinnelsen består anordningen til fermentering av melk av et melkekar (1) hvor det nedsenkes en fermentbæreanordning, som kjennetegnes ved at melkekaret har en steilt oppadhvelvet bunndel (3), i hvis omgivende, smale ringformede bunnkanal (2), kan anbringes en ringformet, perforert fermentbærer (4), med stor diameter som omslutter den oppadhvelvede bunndel. According to the invention, the device for fermenting milk consists of a milk vessel (1) in which a ferment carrier is immersed, which is characterized by the fact that the milk vessel has a steeply domed bottom part (3), in whose surrounding, narrow annular bottom channel (2), an annular, perforated fermentation carrier (4), with a large diameter that encloses the upturned bottom part.

Man bruker som podningsstoffbærer, på kjendt måte, en ringformig hulsylinder av rustfritt materiale, som er åpen i begge ender. Denne med gjær utstyrte hulsylinder senkes ned til bunnen av det med varm melk fyldte kar, og plaseres sådan at den blir stående i den trange fordypning omkring den oppadhvelvede bunndel. A ring-shaped hollow cylinder of stainless material, which is open at both ends, is used as an inoculum carrier, in a known manner. This hollow cylinder equipped with yeast is lowered to the bottom of the vessel filled with warm milk, and placed in such a way that it remains in the narrow recess around the upturned bottom part.

Fordelen ved denne hulsylinder, i for-bindelse med dens anbringelse i en trang, ringformet kanal omkring den oppadh vel-vede del, er den at man i mindre enn 2 mi-nutter kan avkjøle den varme melk i den nedre del av beholderen til passende for-meringstemperatur ved å sette denne nedre del ned i koldt vann. The advantage of this hollow cylinder, in connection with its placement in a narrow, ring-shaped channel around the upward well-weaved part, is that in less than 2 minutes the hot milk in the lower part of the container can be cooled to the appropriate propagation temperature by placing this lower part in cold water.

På denne måte kan man da ta hul-sylinderen med gjæren (sylinderen henger i melkekarets lokk (7) ut efter kort tid og sette den ned i den nye, varme melk uten å måtte vente lenge, og det står da over hul-sylinderen en høy søyle av varm melk, som har den virkning at fremmedbakterier ikke kan trenge inn. In this way, you can then take the hollow cylinder with the yeast (the cylinder hangs in the lid of the milk container (7)) after a short time and put it into the new, warm milk without having to wait long, and there is then above the hollow cylinder a high column of warm milk, which has the effect that foreign bacteria cannot penetrate.

Som varmebeskyttende mantel bruker man ikke lenger, som hittil, en tykk om-hylling, sådan som eksempelvis ved kaffe-varmere, men kun en tynnvegget klokke av et eller annet hårdt stoff, som blir satt over det med varm melk og gjærbærer forsynte melkekar, idet den nedentil lukkes ved å sette den på en svampgummiplate (6). As a heat-protective mantle, one no longer uses, as hitherto, a thick covering, such as for example with coffee warmers, but only a thin-walled bell made of some hard material, which is placed over it with warm milk and milk vessels supplied with yeast, as it is closed at the bottom by placing it on a sponge rubber plate (6).

På denne måte blir det mellem klokken og melkekar et stående et luftsjikt av om- In this way, between the bell and the milk vessel there is a standing air layer of

trent fingerbreddes tykkelse, som alene be-sørger den nødvendige varmeisolasjon. trained finger-width thickness, which alone provides the necessary thermal insulation.

Forsøk har vist at et luftsjikt som ikke kan unnvike, isolerer likeså godt eller bedre enn porøse stoffer, som bare skylder den innesperrede luft sin isoleringsevne. Experiments have shown that an unavoidable layer of air insulates as well or better than porous materials, which only owe their insulating ability to the trapped air.
