Industrial production process of a matured hard cheese and cheese obtainable with said process

Industrial production process of a matured hard cheese made from milk comprising the steps of:

• collecting milk from one or more daily milkings and storing it in a single tank;
• separating said raw milk to obtain cream and at least semi-skimmed milk;
• checking the percentage of the fat fraction present in said at least semi-skimmed milk;
• adding rennet and whey starter;
• cooking in vats to obtain a cheese mass;
• treating the cheese mass thus produced and moulding it to obtain the desired cheese wheels;
• salting said cheese wheels;
• maturing said cheese wheels,
• characterized in that:
• said separating step comprises a step of pre-heating said stored raw milk and a centrifugation step, where said centrifugation step produces cream and skimmed milk with a fat content substantially equal to 0%;
• between the step of separating said raw milk to obtain cream and at least semi-skimmed milk and the step of checking the percentage of the fat fraction present in said at least semi-skimmed milk, it comprises a step of eliminating spores and bacteria from said skimmed milk by means of bactofugation;
• said step of checking the percentage of the fat fraction present in said at least semi-skimmed milk comprises titration of the skimmed milk with spores removed, delivered from the bactofugation process, and addition of cream recovered from the separating step to bring the skimmed milk with spores removed to a fat content of 2.8-3% to obtain titrated milk with spores removed, wherein said re-added cream delivered from the separating step, before being added, undergoes a pasteurizing step and a pre-heating step to 65° C. and then immediately cooled to 35° C.
