Choice of milk heating source for small dairy

V diplomski nalogi je zastavljeno vprašanje o načinu gretja mleka v mali sirarni. Primerja se sistem gretja z elektriko in kombinirani sistem gretja na vročo vodo iz peči ter gretja na elektriko v drugi fazi gretja. V izračunu je upoštevan strošek nadgradnje sirarskega kotla in strošek nadgradnje toplovodne inštalacije v hiši. Ugotovljeno je, da se nadgradnja v kombinirani sistem povrne v petih letih. Nadgradnja se ocenjuje kot smiselna, saj se lahko pridobljena energija iz lesne biomase še poceni.The diploma thesis raises the question of how to heat milk in a small cheese factory. The electric heating system and the combined system of hot water heating from existing central heating system and electric heating in the second phase of heating are compared. The calculation takes into account the cost of upgrading the cheese boiler and the cost of upgrading the hot water installation in the house. The upgrade to a combined system is found to pay for itself within five years. This upgrade is considered reasonable, as the energy obtained from wood biomass can be cheap
