Fields of application

Plants for the production of fish, meat, vegetables, dairy products, fruit, sweets, etc..

The NETTUNO series of washing machines are tunnel machines used for the continuous washing of packaged food products contained in a wide variety of containers (glass jars and bottles, metal cans, thermoplastic tubs and buckets, doypack or flat aluminium multilayer bags).

They are usually placed in the packaging lines upstream of the pasteurisation tunnel or sterilisation autoclave to prevent the dirt covering the containers (as a result of filling and closing operations) from transferring into these machines, making it much more difficult if not impossible to wash the containers before labelling.

They can also be positioned downstream of the pasteuriser or steriliser when it is not necessary to dry the formats, or in pairs with an EOLO series dryer when space does not permit the use of an ATLAS series washer/dryer.

  • Structure made of stainless steel;
  • Centrifugal washing pumps made of AISI 316L stainless steel;
  • Washing pressure regulation system;
  • Washing water containment tanks with thermally insulated walls;
  • Double overlapping static filters for separately removable washing water;
  • Access to filters from both sides of the machine;
  • Mechanical valves for the automatic maintenance of the wash water level in the holding tanks;
  • Flushing water heating via steam coils with provision for condensate return to boiler;
  • Automatic washing temperature management via digital temperature controller and solenoid valve for steam;
  • Total tank drain with manual valve and overflow drain;
  • Washing cages with horizontally developed nozzle tubes with adjustable working angle;
  • Washing stage protective covers with ‘EASY COVER’ opening system that can be opened from both sides of the machine, allowing convenient access for adjustment, cleaning and maintenance;
  • Predisposition for connection to the dedicated or centralised vapour extraction system represented by chimneys in the upper part of the bonnets with suction flow regulation system;
  • Conveyor with thermoplastic modular belt or with stainless steel roller chain;
  • Manually adjustable guides;
  • Conveyor speed management via mechanical variator;
  • Switchboard with stainless steel cabinet with the possibility of positioning it on the machine or separate from it.

A wide variety of accessories allows you to create the perfect machine for your needs:

  • Possibility of lengthening the conveyor at both the infeed and outfeed of the machine in order to connect it to the upstream and downstream conveyors by side-by-side, thus minimising the width of the connecting chute between them and thus the risk of the processed formats tipping over when passing from belt to belt;
  • The machine can be lifted to fit existing lines by adding a structure to which the machine can be fixed;
  • Variation of conveyor speed by inverter;
  • Pneumatically actuated steam valves for tank water heating system;
  • Water level management system in tanks by means of programmable level sensors and pneumatically operated tank inlet valves;
  • System for automatic water replacement in tanks without stopping the washing/drying cycle;
  • Steam kit (the kit includes a steam pressure regulator dedicated to the machine, a safety valve, a filter and condensate drains);
  • Set up INDUSTRY 4.0 ready;
  • EASY’ automatic format changeover system, which sets the machine’s adjustments (width and height of guides, conveyor speed, independent washing water temperature for the various stages) in a totally autonomous manner, based on preset recipes that can be selected via touch-screen directly by the operator.

Modular design

Our machines are designed according to a modular design principle. In fact, our range of machines is made up of a few models that have proven to be suitable for most applications, to which, however, it is possible to add many other models obtained by combining the various modules available. This allows us to offer the most suitable solution for the different needs the customer may have.
