Automatic Rotary Retort for Packaged Food & Canned Food

Product Description:

Automatic Rotary Retort for Packaged Food & Canned Food is designed to sterilize those viscous or ropy or Thick & Sticky packaged foods.

The packaged foods are placed into the Load Container(Sterilization Basket/Sterilization Plates/Sterilization Crates), and the Load Container will be pushed and fixed firmly in the Pressure Vessel, to avoid any damage caused by shaking. Then the Load Containers will rotate at a preset speed during the sterilization process.

Advantages of Rotary Retort:

1. The heat penetrates into products at the fastest speed to ensure the best heat transfer effect, to ensure the perfect sterilization effect, and to achieve the desired F0 value as quickly as possible.
2. Due to the convection of the product by rotation, there is no cold spot inside the package, which is most suitable for products with higher viscosity.
3. Due to the rotating stirring product, the temperature of the package is prevented from being too high, and the excessive cooking of the container and the outer product is prevented from being damaged, and the stratification and precipitation of the product during the heating process are prevented.
Application:

Fluid & viscous products such as rice pudding, condensed milk, beans etc.

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.
