Evo Clean

This machine is designed to perform a semi-automatic CIP (Clean-In-Place) cycle simultaneously on two machines (MEVO series).

• Semi-automatic Clean-in-Place washing
• Suitable for all Marotta Evolution systems and more
• The only C.I.P. on wheels
• Automation management panel equipped with Siemens PLC.

Using the panel on board the C.I.P. trolley, the operator cleans the machines, following a very precise sequence of pre-set phases.

Phase 0 – Preparing the machine for C.I.P.

This machine is designed to perform a semi-automatic CIP (Clean-In-Place) cycle simultaneously on two machines (MEVO SMART and MEVO FAST series). The EVO Clean semi-automatic cleaning system for burrata production machines includes:

• a 16 cubic meter per hour centrifugal pump,
• a sanitizing liquid preparation tank,
• a series of ball valves for flow management,
• level probes,
• filter,
• automation management panel equipped with Siemens PLC.

Using the panel on board the EVO Clean, the operator cleans the machines, following a very precise sequence of pre-set phases.

Phase 1 – Water Push

In this phase, cold water is automatically loaded into the EVO Clean tank. Once the required level is reached, the pump starts and delivers water to both machines (if previously selected). The water flow enters the hopper through the spray ball mounted on the lid; the water pump remains active until the minimum level in the tank is covered. The machine’s dispensers must be started manually and perform suction/delivery cycles, evacuating any residual water and cream from the nozzles onto the carpet. The required rinse time can be selected on the control panel to perform an initial roughing of the machine.

Phase 2 – Washing with Soda

“DIWOFLOW NBE”, the Diversey Monoproduct (or similar product) is indicated for a single CIP phase. It must be used with hot water between 60/65 °C and the indicated concentration is 3%. The recommended application time is between 25/30 minutes for the injector phase and 10 minutes for the dosing gasket pack phase.

After completing Phase 1, the solution is prepared as appropriate. The hot water hose is connected to the inlet valve of the cart’s tank and the product preparation cycle is started using the dedicated button. The system will, as before, check the minimum level to start the pump and begin a product mixing phase until the operator determines the optimal concentration of soda and water. Before starting the final cleaning cycle, it will be necessary to connect the appropriate manifolds to the nozzles and electronic dosers (if present), and finally connect these with special hoses to the filter unit located on the side of the cart.

In this phase, the filling circuit (hopper, dosing chamber, pipes, and injectors) will be washed first, followed by the gasket section of the electronic dosing devices (if present). Using special probes placed on each EVO Clean hopper, the system will ensure that the level never completely covers the spray ball, optimizing internal washing. If the level reaches a certain level, the valve on that circuit closes and interrupts the flow.

The function of the nozzle collector is to recirculate the liquid exiting the injectors and drain it (through the filter) into the EVO Clean recovery tank, where it can be recirculated. For this phase, the cleaning time can also be selected from the control panel, ensuring complete sanitization of the machine. Once the cycle is complete, the system drains the liquid from the tank through the valve on the bottom.

Phase 3 – Final rinse

This phase is identical to Phase 1 and has a time that can be set on the operator panel. Five minutes before the end of the phase, it is recommended to recirculate and drain a peracetic acid solution at a maximum concentration of 100 PPM (parts per million). This facilitates a bactericidal action, leaving the machine sanitized and ready for the next production restart.
