But that's not all - investing in hygienically designed equipment can also lead to long-term cost savings and increased operational efficiency by enabling to extend run times, shorten cleaning times, reduce the use of cleaning chemicals and water, and reduce maintenance costs.
  • the machine of the present invention makes it possible to cut cheese into portions in the different stages of maturation. Determining in an optimal way the weight of the portions obtained by means of a fast, precise, clean cut and free of burrs or crumbs, using either a mechanical or ultrasonic blade. In all the processes carried out by the cheese inside the machine, it runs without there being any element, system or device on its surface. There is no possibility of some type of fluid or particles falling on it, drastically reducing the risk of contamination and thus solving the greatest of the problems described.
  • another of the proposed improvements is to build the self-supporting frame in a fully open sheet metal profile (1) with flush welds, without holes, cracks and corrosion, avoiding hollow tubes where they are not always hermetically sealed, with the contaminating problems that this entails. Self-draining to ensure that the liquid, which can harbor and promote the growth of bacteria, does not accumulate.

That is, while the metecheese places the cheese from the weighing system on a support plate (69a) belonging to the cheese support assembly (69) within the system (6), the cheese extractor conveys the cheese already cut into portions, placing it on the hygienic outlet conveyor (8). It is a carriage that optimizes resources because it is driven by a single gear motor (44).

  • the rotation of the assembly (61) is also carried out by means of a servomotor assembly (66) totally made of IP69K stainless steel by means of an internal crown-pinion system. Since this system does not have to be suspended, it requires a smaller servo motor, saving materials and resources.
  • the assembly (61) is mounted on a lifting carriage (65), actuated by a single pneumatic cylinder (68), improving the current systems that use several lifting cylinders, it carries advantages of maintenance and replacement.
  • the entire system (6) forms a single unit that is completely removable from the machine by means of an extraction carriage (67), since it is a relatively complex system and requires precise adjustments. Therefore, being completely outside the machine, all deep cleaning and repair or maintenance tasks will be carried out effectively, quickly and comfortably, this represents a very important advantage over existing systems.

It has a drive by means of a servomotor (75) that acts by means of a rack and pinion system on the blade support carriage (72). This makes it possible to control the movement of the cutting blade (73), either mechanical or ultrasonic blade depending on the type of cheese, optimizing the alternative cutting movement, that is, moving as necessary without having to go to fixed positions like the system. gear crank.
  • the blade When the machine is stopped or inoperative, the blade has a rest position in which it is fully guarded by a physical barrier (98) operated by a pneumatic cylinder.
