B. Obtinerea berii

In pauza dintre reprize, colegii analizeaza procesul de obtinere a berii in beraria in care se afla. Pentru a obtine produsul final, se trece prin mai multe etape. In fiecare dintre aceste etape se castiga sau se pierde o anumita cantitate de produs (din cauze tehnologice):

Cereale brute => obtinerea maltului (creste cu 0,5%) => macinarea (scade cu 0,5%) => fierberea (scade cu 0,3%) => fermentarea (creste cu 0,4%) => imbutelierea (scade cu 0,2%)

Cata bere se obtine daca se porneste cu o cantitate de cereale care ar fi corespunzatoare pentru 10 litri de bere in cazul ideal (nu se castiga si nu se pierde nimic pe parcursul procesului de fabricatie)?

B. Brewing

In the break, the colleagues analyse the process of making the beer in the brewery where they are. To obtain the final product, there are several production steps. In each step, a small quantity is gained or lost, because of technological reasons.

Grains => malting (increasing with 0,5%) => mashing (decreasing with 0,5%) => boiling (decreasing with 0,3%) => fermentation (increasing with 0,4%) => bottling (decreasing with 0,2%)

How much beer is obtained in the end if for start the quantity of cereal would be for exactly 10 litres of beer in the ideal case (there are no gains or loss in the process)?
