Double Layers Sterilization Autoclave for Packaged Food & Canned Food

Double Layers Sterilization Autoclave for Packaged Food & Canned Food

Product Description:

Double Layers Sterilization Autoclave for Packaged Food & Canned Food has a Water Tank on the upper layer linked together with the autoclave on the lower layer.

Sterilization Water will be stored in the Water Tank, and pre-heated to a preset temperature before the Heating-up Phase starts(Generally speaking, the preset temperature is approx. 80-90℃)Then pushed into pressure vessel and keep heating to 121℃, that shorten the time of Heating-up Phase.

What's more, after Sterilization Phase finish, the hot water will be pumped back to Water Tank and stored for the next Sterlization Cycle.

Compared with the Single Vessel Sterilization Autoclave, this Double Layers Sterilization Autoclave will shorten the Sterilization Time, and save much more Sterilization Water.

One Completed Sterilization Process Cycle:

There are 3 Phases during one completed sterilization process cycle:

1. Heating Phase T1: (Also called Heating-up Stage)

    The Heating Phase is the first phase. It starts from the High Temperature & High Pressure

    steam(approx. 0.20~0.23MPa) injected into water, to heat up the sterilization water, until

    the temperature of sterilization water finally reachs the pre-set Sterilization Temperature.

    As per the general rules, the international standard Sterilization Temperature is appox. 121       ℃, which is suitable for most of packaged foods.

2. Holding Phase T2: (Also called Sterilization Stage)

    After Heating Phase finish, and the temperature of sterilization water reach to 121 ℃, the

    Holding Phase will begin. During this phase, the steam will be stop, and the 121 ℃ will be           kept for a pre-set period of time, and finally achieve the effection of Commercial Sterility.           Meahwile, and meanwhile, the compressed air will also be injected, to increase the pressure

    in the vessel to approx. 0.50~0.80MPa, preparing for the Pressure Balance in the Cooling

    Phase.

    Generally speaking, for regular food with regular package, Holding Phase will be aprrox.

    10~15 minutes. But, it is also effected by many actual factors, such as food material, package

    material, package volume etc.

    For example:

    Meat food will need more time than vegetable or fruit food;

    Plastic package food will need more time than metal package food;

    Large volume package food will need more time than small volume package food.

3. Cooling Phase T3: (Also called Cooling-down Stage)

     Once Holding Phase completed, Cooling Phase will begin. Cool water is pumped into, and  

     circulated continually, until the temperature of packaged foods drop to the normal Room

     Temperature(approx. 30~40℃)

      One important point need to note, with the condensation of steam, both the temperature           and pressure in the vessel will fall, but, the tempereture and pressure inside package won't       fall as fast as vessel, so the inside pressure is higher than outside package. If there's no    

      Back Pressure to balance the pressure between inside and outside of package, the Pressure

      Difference will break up the package easily, For example, pouches and bages will be

      deformed or inflated, then the food materials will be spilled; metal can with a lid, the lid will

      be possible to jump off; glass bottle and glass jar will be break up. 

      That's why the High Pressure Compressed Air injected to vessel during Holding Phase, just

      to offer a Back Pressure during the Cooling Phase, and to keep a balance between inside

      and outside package, and protect packaged food from any damage.

The above are to explain the Operational Principle of Food Sterilization Retort. In practice, all the phases will be hanlded by Control System automaticly, it's very easy to operate.
