A CIP Station (cleaning-in-place) is used for washing the production line filling equipment and it's units surfaces which are being in direct contact with the food product during filling and capping packaging process. The whole washing process takes place on the principle of a "closed" washing cycle.

The basic element of CIP system is being a central washing station. It consists of a system of tanks equipped with heat exchangers, mixing devices and detectors of levels, along side with connected automatic valves, delivering and dozing pumps. All the construction design is based on the time control, conduction, turbidity, temperature and flow measuring systems. The station also have in construction a system of delivery and return pipes for washing medium which are being attached during the washing cycle directly to the production line. As rule standard CIP stations consist of tree tanks. The first tank intakes a general washing agent. The second is supposed for acidic agent. The third is used for system flashing. The CIP stations of smaller capacities usually have only two tanks in their construction design: one tank for washing agent, one for flushing liquid. The most developed and complicated CIP stations may consist of up to six or even more tanks, from which, apart those tree mentioned above also used the tanks for disinfection's, alkaloid's, water's, and for main regeneration solution (such as for PPPP – silicones agent, for example).

So called "complete" cleaning consists of 5 stages and is based on circulation of washing agent in the system. As rule these are:

  • Flushing of a system with cold water
  • Hot water flushing
  • Washing the system with a hot solution of the soda alkaloid
  • Flushing the system with the hot water
  • Cold water system flushing

Similar to above mentioned cycle a cleaning cycle with acidic solution takes place. And all the flow parameters are kept controlled on level that would ensure the intensive washing process in all of the system.

The specification to the CIP station:

  • Two tanks of 1500 litre capacity each,
  • Two pumps: circulation, and washing pump,
  • Piping system with inlet and outlet: two sets of each for two different production units,
  • System of temperature registration and the control of washing agent concentration,
  • An automatic dosing of washing agent,
  • Electronic control panel,
  • Stainless steel performance.
