DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a sterilizing method, apparatus and container of solid matter or liquid matter containing solid matter for use in, for example, preliminary sterilization in a prior stage of retort food.
BACKGROUND ART
Generally, retort food is prepared by mixing unsterilized food materials, such as solid matter and liquid matter, putting in a bag or the like of plastics or aluminum, sealing, applying in a retort apparatus, and heating and processing to sterilize.
In the conventional sterilizing method, since solid matter and liquid matter are heated and processed simultaneously by passing through a sealed bag or the like, processing suited to solid matter and processing suited to liquid matter cannot be done separately, and the processing time tends to be long, ranging from scores of minutes to several hours, and it took a longer time when the thickness of the bag was larger. Accordingly, the food was exposed to high temperature for a long time, which led to problems of deterioration of quality and decline of flavor.
Moreover, when sterilizing solid matter only, hitherto, a large volume was put in a large pressure vessel to sterilize for a long time, and uneven processing and overcooking were likely to occur, or it required weighing or dispensing to distribute into bags after processing, which was often accompanied by deformation, and yet drip or juice exuding from the solid matter at the time of sterilization process remained in the bottom of the pressure vessel, and it was extremely difficult to put it into the bag together with the solid matter, and the drip containing taste components was discarded as waste liquid.
DISCLOSURE OF THE INVENTION
The invention is proposed in the light of the above problems, and it is hence an object thereof to present a sterilizing method and apparatus of solid matter or liquid matter containing solid matter capable of sterilizing and processing efficiently in a short time, while preventing deterioration of quality or decline of flavor.
It is also an object of the invention to present a container suitable for use with such sterilizing method and apparatus.
To achieve the objects, the invention provides a method in which solid matter and liquid matter are heated and sterilized separately, and they are mixed after being sterilized to put into bag or container, and sealed tightly.
In this way, by separately heating and sterilizing the solid matter and liquid matter, mixing them after sterilizing, putting into bag or container, and sealing, the solid matter and liquid matter can be sterilized and processed in an appropriate method each efficiently in a short time. As a result, deterioration of quality and decline of flavor can be prevented, but rather the flavor may be enhanced, and retort food of high quality may be presented.
Also according to the method of the invention, when heating and sterilizing the solid matter independently, the solid matter is weighed and dispensed in each retainer for the portion of one pack, and sterilized, and after being sterilized, it is transferred from the retainer into the bag or container, and sealed tightly.
Thus, when heating and sterilizing the solid matter independently, by weighing and dispensing the solid matter in each retainer for the portion of one pack, and sterilizing, and transferring, after sterilizing, from the retainer into the bag or container, and sealing tightly, the solid matter can be sterilized uniformly in a short time, and the processing time is further shortened, so that the retort food of high quality may be presented, and moreover the job of filling with solid matter after sterilizing is easy, and the drip exuding from the solid matter at the time of sterilization process can be put into the bag or container together with the solid matter.
In a method of the invention, moreover, it is intended to sterilize while rotating the retainer when weighing the solid matter in the retainer for the portion of one pack each and sterilized in dispensed portions.
As a result, the solid matt
