The milk which has been standardised and pasteurised at 65°С is fed from the milk treatment sector into DONI®Double O Vat PF/1/. The coagulation, cutting and drying of the curd grain follow the production parameters of this type of manufactured and are automated or with the assistance of a technologist.
The ready curd-whey mixture is transported through DONI®Drainer/2/, during this process 90% of the whey is drained. The curd grain falls into the trolley which then goes under the press DONI®Prеpress/3/. After 12 to 15 min of pressing the shaped layer is left to lower pH to 5,2 - 5,4. The process lasts for 40 to 60 min.
The cheddared layer is manually cut and fed into DONI®Stretchformer/4/. The pieces are moulded into spherical and semi cylindrical shapes. They fall into a water tunnel for cooling/5/. After the preliminary cooling, the product is transferred into a second tunnel for additional cooling and brining/6/. The finished product is packaged/7/ in brine with low concentration or in vacuum packaging.
This production line is suitable for small and medium dairy factories. The 24 hr production output of the sector can reach 20 000 kg finished product depending on the weight of the pieces. The process is extremely flexible and allows for readjusting of technology and for the use of mould drums with different shapes and weight.
