Common temperature and pressure of sterilizing retort

sterilization machine used for packed food sterilizing
Conventional sterilization temperature and corresponding pressure of the sterilizer:

      The most commonly used maximum sterilization temperature for food high-temperature sterilization is 121°C,

because the ideal lethal condition for the target bacteria we want to kill - Clostridium spp. is: 121°C, and the pressure corresponding to 4 minutes is 0.15-0.22Mpa ( 1.5-2.2 kg).


It is wrong to say that horizontal sterilizers are only used for high-temperature sterilization. In addition to high-temperature sterilization, sterilizers can also be used for bus sterilization (low-temperature sterilization),

such as 92 degrees Celsius sterilization. The temperature of the sterilizer can be adjusted and set, and the range that can be set is greater than normal temperature and less than 130 degrees Celsius.

Of course, the lower the temperature, the worse the sterilization effect, and the longer the corresponding holding time.

   Commonly used high temperature sterilization temperatures are:

        108 degrees Celsius, 116 degrees Celsius, 118 degrees Celsius, 121 degrees Celsius.

        The most commonly used sterilizer is high-temperature sterilization, but it can also be used for low-temperature sterilization (bus sterilization). It can also be used as a large steamer, such as corn greening.

It can also be used as a large pressure cooker, such as ripening and soaking sea cucumbers.
