1 3Technological description Af t er repas t eur ization, milk is cooled down to t he processing temp eratur e and pump e d in t o a c o a g ulation vat. T he coagulation process t akes place up on the addi t ion o f star t er and acid. T he resul t ing cur d is cu t by ver t ical and hor izontal har ps, which ar e par t o f the vat. T her mal cur d t r e atment is done using a membrane heated with water inside the heating jacke t. When the g r ains ar e proper l y set, the cur d is pump e d via a membrane pump to the whey-draining belt. T he separ ated cur d is immer sed in t he r insing water inside t he bu f f er t ank and t hen pump e d t o t he r insing- c o oling t ower. Inside t he t ower, t he hydr o d ynamic r insing o f t he r emaining whey and cooling o f t he g r ains t ake place. T he cooled g r ains ar e separ ated f r om water on t he dr aining belt and conveye d t o t he cr eamer for t he creaming process. T he amoun t o f cur d and cr e am is deter mined by tensometric scales which ar e buil t in t o t he creamer. 3 The cot t age cheese production line consis t s o f the following equipment: 6і1 pas t eur izing sys t ems: for milk(1), for technological water(2) 6і1 processing equipmen t for cur d produc t ion: coagulation vat(3), whey-draining belt (4), rinsingc o oling t ower(5), water dr ainer(6), cr e amer(7) 6і1 s t orage t anks: for cr e am(8), for technological water(9) A ll line equipmen t is au t omaticall y controlled t o enable easy operation, indus t r ial safet y and repeatability of the technological process.
