FPR 72L

Hourly output up to 2000 kg
The FPR 72 L moulder is a machine suitable for the moulding and pre-cooling of pasta filata cheeses having weights from 300 gr to 5 kg, in cylindrical or parallelepiped shapes.
This machine is suitable for the production of the following cheeses:
MOZZARELLA FOR PIZZA – KASAR – MELTED CHEESES AND FOODSTUFFS

The stretched dough is introduced into the hopper and it is conveyed to the head by means of two counter-rotating augers, thus filling the moulding pipes according to the programmed volumetric adjusting. During the head rotation, the product is indirectly cooled by means of the cold water circulating outside the moulding pipes, until to reach a stable enough shape for continuing the hardening phase without moulds into an automatic vat.

Construction features

  • Machine completely built in AISI 304 stainless steel and plastic materials certified for the food use.
  • Parts in contact with the cheese are coated with non-sticking material.
  • Feeding hopper built in AISI 304 stainless steel, easily dismountable from the machine body simply unhooking the blocking knobs.
  • Elbow pipe in the augers chamber final section, externally heated by a double jacket equipped with electrical heating elements.
  • Moulding and pre-cooling section composed by parallelepiped or cylindrical moulds, equipped and welded on a stainless steel disk, complete with internal and external band for the cooling water containment.
  • Weight volumetric adjusting and pneumatic product automatic ejector.
  • Hydraulic plant connected to a self-priming pump, for the cooling water circulation start-up.
  • Dismountable stretching water discharging filter.
  • Dough feeding augers built to be easily dismantled without using any tool.
  • Adjustable augers and moulding head rotation speed.
  • PLC for the control of all sensors against accidents and for the machine operation.
  • Low tension fed external push button panel, with controls subdivided for the desired working type programming for every section.
  • Motorizations protected by AISI 304 stainless steel guards.
  • Motorization equipped with spacer to allow the cleaning between motor and moulding chamber.
  • Motorizations with oil bath, watertight speed variator, complete with guard which allow, in case of oil leakages, its discharge on the ground, thus avoiding any cheese pollution.
  • Connections with bending radius built in such a way to avoid any stagnation point.
  • PTC or PT100 probe for detecting the water temperature into the double jacket
  • Watertight electrical control panel with IP 65 protection degree, built in AISI 304 stainless steel, complete with electronic devices for the processing speed adjusting and the operator’s safety control.
  • Dismantling easiness of the movable parts without using any tool and complete inspection possibility.
  • Set of safety sensors against accidents to start the machine stop up in case of guards opening

Advantages

  • Possibility to mould cheeses having different weights and shapes by means of the moulding head replacement.
  • Cheese pre-cooling is made by means of tampons immersed into a cooling head. This allows the cheese to be better cooled than in those machines using showers hardening, thanks to a larger contact surface and a better thermal efficiency.
  • In addition to the certain advantages coming from the fact that the operator is not more obliged to fill, empty and wash the moulds, the adopted cooling system avoids also any contamination caused by the manipulation of the cheese, as the product is directly ejected into the mechanized vat.
  • The cooling method implying the head immersion into cold water (where there is not any direct contact between the moulding pipes filled with the cheeses and the cold water), in comparison with the shower cooling does not present any contamination problem. In fact, during the shower cooling, in case of a lightly worn tampon, cold water would enter the mould filled with the stretched dough. This may cause the cheese contamination with the consequent decreasing of the product shelf life.
  • Tubular heat exchanger installed on machine border. Other machines present on the marked generally need external heat exchangers, normally plate heat exchangers, with consequent maintenance problems.
  • Tampons are built with food suitable polyethylene head, resistant to the washing solutions and to the high temperatures adopted during this operation.
  • Stretched dough conveyor, from the augers chamber to the cooling head, heated by electrical heating elements.
  • Controls simple use.
  • Easy disassembly by the operator of parts in contact with foodstuffs without the help of any tool for facilitating the washing and sanitation operations.
