We will contribute to the development of an enriched society by creating new value with aseptic technology.

History & Features

  • History

    DNP’s first aseptic filling machine launched in 1976 to produce single-use coffee creamer packs. The system was designed to allow the UHT sterilized coffee creamer to be filled and sealed in a hydrogen peroxide-sterilized lid and base within an aseptic environment. This concept has been the basis for the development and sale of various aseptic filling systems (PET bottle, Carton, Cup, Pouch, BIB, etc.) that use hydrogen peroxide sterilization for the last 50 years.

  • Features

    Our Aseptic PET bottle filling systems offer three major advantages: high productivity, high sterilization effectiveness, and low costs. In Japan, DNP has the largest market share for aseptic filling systems.

    2-step sterilization

    DNP launched a new aseptic filling system for PET bottles with a 2-Step Sterilization system that combines preform sterilization with compact bottle sterilization. This has successfully reduced the size and TCO of aseptic filling systems. The 2-Step Sterilization process is one of the most sterile and reliable aseptic filling systems in the world (up to 60,000 b.p.h).

    • F₀ method

      F₀ method is a new way to maintain sterility while still significantly reducing SIP time compared to the conventional method. Not only does this improve productivity, but it also reduces CO₂ emissions by using less steam.

    • CSIP

      CSIP performs CIP and SIP simultaneously. This eliminates the need for traditional SIP processes and allows only high temperature, short duration CIP to be used between productions.
