The aim of this paper is the analysis and examination of the industrial processes for Mozzarella pizza cheese (hereafter referred to as pizza cheese). Specific phases and mechanical devices are studied in order to optimise and rationalise the production cycle. This goal is reached by developing a new and innovative forming method. At present pizza cheese is produced in 1-5 kg pats whereas, as this paper intends to highlight, by forming the cheese in smaller-sized dimensions (5-10 g) the processes will benefit in terms of energy consumption and use of resources (equipment, water, time etc.).

The paper deals with an innovative process for pizza cheese production, by focusing mainly on the forming phase; a double-screw extruder with a productivity of 20 kg/h was designed and tested in order to evaluate its functionality and applicability. The most relevant spin-offs deriving from the new forming device are the elimination of the pre-hardening phase, the reduction of the chilling time of about 10-fold, the reduction of the total processing time of about 25% and the diminution of the refrigerant water consumption. © 2003 Elsevier Science Ltd.

Abstract

The aim of this paper is the analysis and examination of the industrial processes for Mozzarella pizza cheese (hereafter referred to as pizza cheese). Specific phases and mechanical devices are studied in order to optimise and rationalise the production cycle. This goal is reached by developing a new and innovative forming method. At present pizza cheese is produced in 1-5 kg pats whereas, as this paper intends to highlight, by forming the cheese in smaller-sized dimensions (5-10 g) the processes will benefit in terms of energy consumption and use of resources (equipment, water, time etc.). Another advantage would be that the customer would be provided with a ready-to-use product, without the need for additional cutting. The paper deals with an innovative process for pizza cheese production, by focusing mainly on the forming phase; a double-screw extruder with a productivity of 20 kg/h was designed and tested in order to evaluate its functionality and applicability. The most relevant spin-offs deriving from the new forming device are the elimination of the pre-hardening phase, the reduction of the chilling time of about 10-fold, the reduction of the total processing time of about 25% and the diminution of the refrigerant water consumption. © 2003 Elsevier Science Ltd.
