  • Publication number: 20210127694
    Abstract: A pasteurization system is configured for incorporating a food treatment system which includes a mix hopper, a freezing cylinder, and a cooling condenser. The pasteurization system includes a pasteurizing pipeline and a cooling module. The pasteurizing pipeline includes a forwarding passage guiding a heat exchanging medium from the compressor to the mix hopper and the freezing cylinder, and a returning passage guiding the heat exchanging medium from the mix hopper and the freezing cylinder back to the compressor through the cooling condenser. The cooling module is operatively coupled at the returning passage for not only reducing the temperature and pressure of the heat exchanging medium at the returning passage but also releasing an excessive energy of the heat exchanging medium before returning back to the compressor.
