Abstract
Voda se koristi u pogonu kao sirovina pri kuhanju piva, za sanitaciju pogona te u sustavima za hlađenje/grijanje uređaja. Craft pivovare su male pivovare s malom godišnjom proizvodnjom, nude raznovrsne tipove piva i postaju sve veći trend u svijetu. Zbog male proizvodnje, nisu pogodne za ugradnju sistema za obradu vode te je jedini način uštede pri potrošnji vode optimizacija procesa i provjera učinkovitosti. Istraživanje se provodi s ciljem određivanja potrebne količine vode za ispiranje sredstva za čišćenje fermentora i izračuna uštede. Titracijom se mjeri koncentracija zaostalog sredstva u vodi te se na taj način utvrdila potrebna količina vode za ispiranje. Ušteda se mjeri izračunavanjem razlike potrebne količine vode za ispiranje i korištene količine vode po pranju fermentora, prosjek iznosi 20L za fermentor volumena 4000L i 30L za fermentor volumena 8000L. Također se provodila metoda provjere čistoće nakon završenog pranja uz pomoć NBB-B tekuće hranjive pogloge. Svi uzorci su negativni što upućuje na ispravnost metode pranja fermentora.
Abstract (english)
Water is being used in breweries as raw material for beer production, plant sanitation and in cooling/heating systems. Craft brewers are small breweries with small annual production, offering various types of beer and becoming an increasing trend in the world. Because of their small production, they are not suitable for an instalation of water treatment system and the only way to save on water consumption is optimizing the process and checking efficiency. This research is carried out to determine the required amount of water to rinse the fermenter cleaning agent and to calculate the savings. Titration is used to measure the concentration of residual in water and thus determine the required amount of water. The savings are measured by calculating the difference between the required amount of rinsing water and the amount of water used to rins the fermenter. The average water saving is 20L for a 4000L volume fermenter and 30L for a fermentor volume of 8000L. Also, the purity-checking method was carried out using NBB-B liquid culture media. All samples are negative indicating the correctness of the fermentor washing method.
