- the final F0 value is 6.75. Met.
- the movable base is slid at the same frequency from the start to the end of the process.
- the on / off control and rotation speed of the motor that is the rotation drive source during retort operation can be freely controlled, and by controlling the motor on / off control and rotation speed, during the retort processing.
- the sliding frequency of the movable table can be controlled freely.
- FIG. 11 shows an example of changing the sliding pattern by controlling the sliding frequency of the movable table during retort operation to the optimum frequency according to the ambient temperature!
- the movable table is not slid until the ambient temperature reaches 80 ° C from the start of the treatment (ie, the motor is off and the frequency is OHz), and the sterilization temperature reaches 80 ° C, which is the sterilization temperature.
- Slide at 30Hz, slide at 45Hz during sterilization slide down to 35Hz from the end of sterilization until it cools to 80 ° C in the cooling process, and the ambient temperature is 80 ° C
- the sterilization process is carried out in a pattern that stops sliding when the pressure drops to.
- the product temperature can be controlled by arbitrarily changing the sliding pattern during processing, so an optimal sliding pattern must be obtained in advance for each type and size of the item to be sterilized. If it is stored in the controller as a program, it can be simply re-set according to the type of product to be sterilized.
- the sliding pattern can be changed by monitoring the force that was performed according to the ambient temperature in the above example, for example, the product temperature of the object to be sterilized, and changing the sliding frequency by changing the product temperature.
- the retort product sterilization method and sterilization apparatus of the present invention can be used for sterilization of retort products encapsulating food, pharmaceuticals, etc., and in particular, solids and high-viscosity contents can be used as packaging bags. Retort product enclosed in a package with a large or thick packaging bag Is particularly preferred.
