DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This is a national phase application of PCT/IT93/00019 filed Mar. 8, 1993 and based upon Italian national applications B0 92 A 000088 and B0 93 A 000063 of Mar. 13, 1992 and Feb. 23, 1993 respectively under the International Convention.
FIELD OF THE INVENTION
The present invention the production of pasta filata cheese, such as mozzarella and the like.
BACKGROUND OF THE INVENTION
It is known that various types of pasta filata cheese are presently produced in form of a cord or strand from which single portions are severed.
In order to obtain such cord, the cheese paste from out of the molding machine is fed into a hopper.
The cord delivered from the hopper is subjected to a manual tug that provides a stretching of the strand.
Obviously, a manual process brings various hygiene and productivity inconveniences.
In order to overcome such disadvantages many apparatuses are known for stretching of the cheese cord by means of rolls (see JP-57-206334).
The document U.S. Pat. No. 4,288,465 discloses a method and an apparatus suitable for shaping pasta filata cheese comprising the steps of extruding pasta filata cheese through extruding means in order to obtain a strand of cheese which is brought to a pair of adjacent, rotating drums around which the cheese strand is wrapped. The drums are operated at a speed higher than the extrusion speed to cause the strand to stretch.
The strand then passes through a cooling vat under tension and, after pulling and cooling, it is cut to length suitable for packaging.
The above apparatus provides no effective means suitable for controlling automatically the tension applied to the stretched strand, except that the speed of the drums could be controlled by the adjustable power supply of the motor of the same drums.
The mentioned apparatuses have not solved effectively the problems connected with shaping pasta filata cheese into form of cord.
OBJECTS OF THE INVENTION
The object of the present invention is to provide a method that allows to obtain automatically stretched cords of pasta filata cheese.
A further object of the invention is to provide an apparatus that allows to carry out the above mentioned method, in a simple and effective way with increased productivity.
SUMMARY OF THE INVENTION
The objects are obtained in a method for shaping pasta filata cheese into cords, which includes: least one cord of pasta filata cheese; higher than the coming out speed of the cord from the extruding means thereby stretching the cord located between the extruding means and transport means, as well as a cord section on the transport means; and transversally cutting the stretched pasta filata cord in single portions.
An apparatus for shaping pasta filata cheese into form of cord includes: cord; of the cord from the extruding means, so as to cause a stretching in the free strap of the same cord located between the extruding means and transport means and in the cord section situated on the transport means; and stretched pasta filata cord.
The described method allows to obtain, in a fully automatic way, stretched cords of pasta filata cheese, with clear advantages in terms of the production, homogeneity and hygiene of the product are concerned.
Moreover, the aforementioned method can be carried out by means of a very simple apparatus and allows to adjust the paste stretching degree, by controlling the speed of the transport belt.
