Abstract

U radu se obrađuju teme vezane uz filtraciju vina pomoću pločastih filtera. Opisuju se i drugi postojeći načini filtriranja vina. Iznose se rezultati organoleptičke i kemijske analize vina. Organoleptička analiza vina temelji se na analizi vanjskog izgleda. Kvalitetan izbor filtera znatno utječe na cjelokupni sastav vina, posebno kod crnih i aromatičnih vina. Tijekom filtracije korišteni su pločasti filtri Seitz: K300, K100 te EK. Filtar ploče K300 i K100 služe za finu, dok EK filtar ploče... More služe za sterilnu filtraciju. Dimenzije filtar ploča su 20x20 cm. Prilikom filtracije korištene su Graševina, Pinot sivi, Sauvignon te mješavinu crnih vina (Cabernet Sauvignon, Merlot i Zweigelt). Less

Abstract (english)

In this thesis it is processed topics related to wine filtration using plate filters. Even other ways of filtering wine are described. The results of organoleptic and chemical analysis of the wine are presented. Organoleptic wine analysis is based on external appearance analysis. Quality filter selection significantly affects on overall composition of wines, especially for red and aromatic wines. Seitz plate filters: K300, K100 and EK were used during filtration. Plate filter K300 and... More K100 were are used for fine filtration while EK filter are for sterile filtration. Dimension of plate filters are 20 x 20 cm. During filtration they were used Graševina, Pinot gray, Sauvignon and red wine blends (Cabernet sauvignon, Merlot and Zweigelt). Less
