The PAA technology developed by GEA uses only one sterilizing solution, based on Peracetic acid, to sterilize the environment and the packaging materials. Only five parameters have to be controlled to achieve a robust and reliable sterilization: pressure, temperature, concentration, flow rate and contact time.
A full-cone, no clogging penetrating nozzle is used for internal bottle sterilization. The efficiency of each nozzle is automatically checked by a ’Smart Sensor’ that ensures the proper sterilization of each bottle. The high-performance spraying system keeps treatment times very short while guaranteeing up to 6 Log reduction on B.atrophaeus.
External sterilization is performed on the bottle surface with dedicated manifolds. A strong mechanical and chemical action allows an effective removal action on Cold Spot contamination reaching the highest demanding line validation protocols.
The PAA solution is recovered and, once concentration and temperature are restored, reused in a closed loop.
ECOSpin2 Zero has a no valve design sterilizer: no valve design means a simpler machine with no electrical parts allowing easier maintenance and less wear and tear.
After sterilization the bottle is rinsed with sterile water at ambient temperature, guaranteeing a total peroxides residual of below 0.5 ppm (as per FDA regulations). The non-penetrating nozzles’ pulsing spraying mode is designed for minimum water consumption. Construction of the rinser is very easy with a minimized need of maintenance. As an option, ECOSpin2 Zero is equipped with a peroxide neutralization system (both in vaporized and liquid phase) that prevents any release of peroxide to the external environment.
