Description

Przedmiotem wynalazku jest sposób wytwarzania etanolu z serwatki.Znanych jest kilka metod wykorzystania serwatki do produkcji etanolu. Stosuje sie w nich odpowiednie drozdze zdolne do fermentacji etanolu. Metoda polegajaca na fermentacji ultrafil- tratu, otrzymanego z zageszczonej serwatki ze wzgledu na niskie stezenie etanolu w nastawie, rzedu 1,8-2,2% objetosciowych jest nieekonomiczna, gdyz wymaga duzego nakladu energii na oddestylo¬ wanie etanolu. Znana jest równiez metoda polegajaca na fermentowaniu serwatki zageszczonej.W metodzie tej zmniejsza sie zuzycie energii na oddestylowanie etanolu, jednak ogólny naklad energii jest stosunkowo duzy, a proces fermentacji jest dlugi. Proponowano równiez sposób polegajacy na produkcji etanolu z mieszaniny zacieru zbozowego i serwatki. Metoda ta jest jednak droga ze wzgledu na koszt surowca zbozowego. Wad tych nie posiada sposób wedlug wynalazku, który umozliwia wykorzystanie serwatki do otrzymania etanolu w dwuetapowym skojarzonym procesie produkcji etanolu z mieszaniny serwatki i melasy.Sposób wedlug wynalazku polega na tym, ze serwatke, ultrafiltrat serwatki lub serwatke 2-3 krotnie zageszczona zakwasza sie do pH 4-6, korzystnie 4,5 — pasteryzuje i zaprawia drozdzami zdolnymi do fermentacji laktozy w ilosci 1-10% suchej masy drozdzy, korzystnie 5% suchej masy drozdzy w stosunku do laktozy zawartej w serwatce. Przygotowany w ten sposób nastaw poddaje sie fermentacji w temperaturze 25-40°C, korzystnie 35°C w czasie niezbednym do calkowitej przemiany laktozy na etanol. Do odfermentowanej serwatki dodaje sie spasteryzowana melase oraz biomase drozdzy Saccharomyces cerevisiae, zwlaszcza w formie brzeczki melasowej z namno¬ zonymi drozdzami i prowadzi drugi etap fermentacji wedlug znanego sposobu stosowanego w melasowym przemysle spirytusowym. Po zakonczeniu drugiego etapu fermentacji przeprowadza sie oddestylowanie spirytusu w znany sposób. Ilosc melasy dodanej do przefermentowanej serwatki ustala sie w taki sposób, aby stezenie etanolu w nastawie po zakonczeniu drugiego etapu fermen¬ tacji wynosilo 7-11%. Wywar po destylacji moze byc wykorzystany jako pasza.Przyklad I. 100dm3serwatki zakwaszonej do pH = 4,5 pasteryzuje sie w temperaturze 85°C przez 15 sekund i schladza do temperatury 35°C.

Naklad 100 egz.Cena 100 zl4 PLThe present invention relates to a method of producing ethanol from whey. Several methods of using whey to produce ethanol are known. They use suitable yeasts capable of fermenting ethanol. The method based on the fermentation of ultrafiltrate obtained from concentrated whey due to the low concentration of ethanol in the setting, in the order of 1.8-2.2% by volume, is uneconomical, as it requires a lot of energy to distill off ethanol. There is also a known method of fermenting concentrated whey. This method reduces the energy consumption for ethanol distillation, but the overall energy input is relatively high and the fermentation process is long. A method based on the production of ethanol from a mixture of grain mash and whey has also been proposed. However, this method is expensive due to the cost of the raw grain. These disadvantages do not exist in the method according to the invention, which enables the use of whey to obtain ethanol in a two-stage combined ethanol production process from a mixture of whey and molasses. The method according to the invention consists in the fact that whey, whey ultrafiltrate or whey concentrated 2-3 times acidified to pH 4-6, preferably 4.5, are pasteurized and treated with lactose fermentable yeasts in an amount of 1-10% dry weight of yeast, preferably 5% dry weight of yeast in relation to the lactose contained in the whey. The settings prepared in this way are fermented at a temperature of 25-40 ° C, preferably 35 ° C, for the time necessary for the complete conversion of lactose into ethanol. To the fermented whey is added pasteurized molasses and Saccharomyces cerevisiae yeast biomase, especially in the form of molasses wort with enriched yeast, and the second fermentation stage is carried out according to the known method used in the molasses spirit industry. After the second stage of fermentation has been completed, the spirit is distilled off in a known manner. The amount of molasses added to the fermented whey is adjusted so that the ethanol concentration in the setting after the completion of the second fermentation step is 7-11%. The stock after distillation can be used as a fodder. Example 1 100 dm3 of whey acidified to pH = 4.5 is pasteurized at 85 ° C for 15 seconds and cooled to 35 ° C. Then 1.4 liters of Kluyveromyces fragilis yeast milk with about 15% dry weight of yeast are added and fermented for 20 hours until the lactose is completely fermented. The fermented cheese-2 133 721 cotton wool is used to dilute 28 kg of pasteurized molasses. The setting thus obtained is mixed in a ratio of 1: 0.9 with molasses yeast wort with the multiplied yeast biomass Saccharomyces cerevisiae and the second fermentation stage is carried out at 30-32 ° C for 25-30 hours. After fermentation is completed, the spirit is expelled in a known manner. Example II. 100 dm of double-concentrated whey with 8% anhydrous lactose is acidified to pH 4.5, pasteurized at 85 ° C for 15 seconds and cooled to 35 ° C. Then 2.8 liters of kluyveromyces fragilis milk with about 15% dry weight of yeast are added and fermented for 40 hours until the lactose is completely fermented. The fermented whey is used to dilute 20 kg of pasteurized molasses. The resulting setting is mixed in a ratio of 1: 0.9 with the yeast molasses wort with the multiplied Saccharomyces cerevisiae yeast biomass and the second fermentation stage is carried out at 30-32 ° C for 25 -30 hours. After the fermentation is completed, the spirit is stripped off in a known manner. Patent claim A method for producing ethanol from whey, characterized in that pasteurized whey, whey ultrafiltrate or whey concentrated 2-3 times is acidified to pH 4-6, preferably 4.5 is pasteurized and is treated with fermentable yeasts in the amount of 1-10%, preferably 5%, of the dry weight of yeast in relation to the lactose contained in the whey, and then, after fermentation is completed, the fermented fermented whey is mixed with molasses and the biomass of the yeast Saccharomyces cerevisiae by carrying out the second fermentation stage in The printing studio of the Polish People's Republic.
