Retort P&ID:

Control system:

1. A retort is a pressure vessel designed to sterilize containerized food.
2. The Control system will automatically control temperature and pressure by maintaining the
   safety parameters.
3. The Steam-Air retort is suitable for canned product.
4. Special perforated layer pads ensure good steam and water flow between product layers.
5. The basic process:
   • Load Product and close door
   • Select Process time and temperature – Start process
   • A Pneumatic piston devise will lock the door and process will not start if signal from an
     additional proximity sensor indicates that door is locked
   • Steam control valve opened and vent valve opened
   • Venting continuous until a certain temperature is reached to ensure most air is vented out the vessel. Required for good heat transfer.
   • The Cook cycle starts when vent valve is closed
   • A 4-20mA steam modulating valve ensures accurate temperature control
   • At end of heating process, the steam valve is shutoff and cold water is slowly introduced via an on/off valve
   • As the steam collapses, compressed air can be introduced to prevent cans peaking especially during start of the cooling cycle. This becomes more important when running large can sizes.
   • Water is metered into the vessel via electronic meter to know when it is filled.
   • Water will be pushed back to the Cooling water system with compressed air (Return pump can be supplied if required instead)
   • Water can be circulated through the retort for cooling if required (pump supply to be discussed in this case)
   • After cooling, water will be pushed back to Cooling water system or drained.
   • Process complete and deactivate Pneumatic piston and open mechanically
   • Unload product
6. All temperature and pressures will be automatically logged and stored for traceability and record keeping.
7. All parameters will be displayed on a Colour touch screen
8. All critical measuring instruments will have calibration certificates
9. SFB Engineers can provide heat distribution in the retort and heat penetration trial into the product, if required.
