  Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings.

FIG. 1 is a flowchart showing the configuration of a solid material heat sterilization method 100 of the present invention.
First, this solid heat-sterilizing method 100 includes a filling step of weighing and filling a solid material in a sterilization container described later, and a chamber transfer for setting the solid material filled in the sterilization container filled with the solid material inside a dedicated chamber. A loading step, a sealing step for confining the solid matter packed in the sterilization container inside the chamber, a deaeration step for replacing the air inside the chamber with steam, a heating step for heating and sterilizing the solid matter packed in the sterilization container with steam, and heat sterilization A temperature maintaining step for keeping the temperature of the sterilized container stuffed solid constant, a cooling step for cooling the sterilized container stuffed solid after the heat sterilization treatment, and an unloading step for taking out the cooled sterilized container stuffed solid Configured. Each process will be described later with reference to FIGS.

FIG. 2 is an explanatory view of relevant parts showing a filling process according to the present invention.
This filling step consists of filling a predetermined sterilization container 10 described below with a predetermined amount of solid matter. In the following description, a sterilization container 10 filled with a predetermined amount of solid matter is referred to as a sterilization container stuffed solid substance 14.

  The sterilization container 10 is provided with a plurality of through-holes 12 on the side surface and bottom surface for allowing a heating fluid such as steam or a cooling fluid such as sterile water to flow into and out of a container body 11 that contains solid matter. It is configured to include a ring 13 that prevents the side surface through-hole 12 from being blocked and vapor or the like from becoming difficult to flow in and out when it is set in a chamber holder (sleeve). The sterilization container 10 is configured to improve so-called heat flow. As a result, the solid matter can be sterilized or cooled in a short time in a heating step or a cooling step described later. Further, the inner peripheral surface of the container main body 11 is finished so that the surface roughness is small so that the solid matter hardly adheres.

FIG. 3 is an explanatory view of relevant parts showing a chamber transfer process according to the present invention.
This chamber transfer process consists of housing the sterilization container-packed solid material 14 in which a predetermined amount of solid material is filled in the sterilization container 10 in the following dedicated chamber 20.

  The chamber 20 is a small chamber dedicated to sterilization having a structure in which the upper and lower surfaces can be opened one by one, and includes a chamber main body 21, an upper lid 22, and a bottom lid 23. Moreover, the chamber 20 seals the solid substance 14 filled in the sterilization container, and performs heat sterilization with steam or cooling with aseptic water. Further, the upper lid 22 communicates with the non-sterile chamber and the bottom lid 23 communicates with the aseptic chamber. Therefore, when the top cover 22 is open, the bottom cover 23 is closed, and conversely, when the bottom cover 23 is open, the top cover 22 is closed.

  The chamber main body 21 includes a sleeve 21a for supporting the sterilization container-packed solid material 14 in the lateral direction, and a path 21b for introducing steam or sterile water flowing from the second flow path 22b to the outside of the sleeve 21a. Thereby, the sterilization container stuffing solid substance 14 can be heat-sterilized or cooled from the outside. Further, the ring 13 of the sterilization container 10 ensures a clearance (gap) between the inner peripheral surface of the sleeve 21a and the outer peripheral surface of the sterilization container-packed solid material 14. Thereby, the vapor | steam or aseptic water which permeated the inside of a container flows out to the exterior of a container, spreading over the whole solid substance. As a result, the sterilized container-filled solid material 14 is suitably heated or cooled by steam, sterile water, or the like.

  The upper lid 22 is formed with a first flow path 22a and a second flow path 22b for supplying steam, sterile water or the like into the chamber. Further, for example, steam or aseptic water can flow in and out through the through-hole 12 of the sterilized container-filled solid material 14 and can evenly reach the entire solid material, for example, in a concentric shape centering on the first flow path 22a. Second flow paths 22b are respectively provided.

  On the bottom lid 23, a convex portion 23a for supporting the solid matter 14 packed in the sterilization container in the vertical direction (axial direction), and steam used for heat sterilization of the solid matter or aseptic water used for cooling the same are discharged to the outside. A discharge valve 23c for stopping the flow of the discharged steam or adjusting the flow rate is connected downstream of the discharge hole 23b. The bottom surface of the sterilization container-packed solid material 14 is supported at a position higher than the inner bottom surface 23d of the bottom lid 23 by this convex portion 23a, so that vapor or the like that has entered the container easily flows out to the outside, or It becomes easy to enter the inside through the bottom surface of the container.

FIG. 4 is an explanatory view of relevant parts showing a sealing process according to the present invention.
In this sealing step, the sterilization container-packed solid 14 is set on the sleeve 21a of the chamber main body 21 and the convex portion 23a of the bottom lid 23, and then the upper lid 22 (heating head) is lowered to place the sterilization-packed solid 14 in the chamber main body 21. Consisting of sealing inside.

FIG. 5 is an explanatory view of relevant parts showing a deaeration process according to the present invention.
In this deaeration step, the discharge valve 23c connected downstream of the discharge hole 23b is opened, and high-temperature steam is supplied into the chamber from the first flow path 22a and the second flow path 22b of the upper lid 22, It consists in replacing the air inside the chamber with steam by exhausting the air out of the chamber. First, the vapor from the first flow path 22a flows into the sterilized container stuffed solid material 14, exits the container through the through-holes 12 on the side and bottom surfaces of the container, and expels the air in the container out of the container. On the other hand, the expelled air flows outward, but mixes with the vapor from the second flow path 22b and is exhausted out of the chamber through the discharge hole 23b.

FIG. 6 is an explanatory view of relevant parts showing a heating process according to the present invention.
In this heating step, the discharge valve 23c connected downstream of the discharge hole 23b is closed, and high temperature steam is supplied into the chamber from the first flow path first flow path 22a and the second flow path 22b of the upper lid 22, The solid material filled in the sterilization container-packed solid material 14 is heated with steam while the inside of the chamber is pressurized with steam. When the solid is pressurized and heated with steam in a state where the discharge valve 23c is closed, the temperature of the solid is preferably instantaneously increased as will be described later with reference to FIG.

  In addition, when a part of the vapor is liquefied and accumulated at the bottom of the chamber to be stored water, the exhaust valve 23c is slightly opened to drain the stored water to such an extent that the pressure in the chamber does not extremely decrease, and then the exhaust valve 23c is again discharged Is closed and the solid is heated with steam. Alternatively, the exhaust valve 23c is opened slightly to heat the solid with steam while draining the stored water.

FIG. 7 is an explanatory view of relevant parts showing a temperature holding step according to the present invention.
In this temperature maintaining step, the discharge valve 23c connected downstream of the discharge hole 23b is minutely opened to discharge condensed water, and high-temperature steam is generated from the first flow path 22a and the second flow path 22b of the upper lid 22 into the chamber. Then, the solid material filled in the sterilized container-packed solid material 14 is heated with steam. In this case, the solid is heated with steam so that the temperature and pressure inside the chamber are constant.

FIG. 8 is an explanatory view of relevant parts showing a cooling process according to the present invention.
In this cooling process, after the sterilization is completed, the supply of steam is stopped, sterile water is supplied from the first flow path 22a and the second flow path 22b instead of the steam, sprayed to the solid matter, and the discharge valve 23c is slightly opened. Reduce the pressure (depressurize) and cool down. After the temperature maintenance is completed (after sterilization is completed), normally, the supply of steam is stopped, and if the temperature is not lowered while the discharge valve is slowly opened and the pressure is gradually lowered, the solid matter is caused by the pressure difference between the inside and outside of the solid matter. It becomes damaged itself, or moisture in the solid material evaporates due to a sudden pressure change. However, in this cooling process, aseptic water is sprayed onto the contents or sterilization container at the time of depressurization, thereby promoting cooling of the solid material without causing moisture inside the solid material to evaporate or being damaged by the pressure difference. It is possible to cool in a short time. It is possible to use aseptic gas in addition to aseptic water. Alternatively, the solid may be cooled using both sterile water and sterile gas.

FIG. 9 is an explanatory view of relevant parts showing a carry-out process according to the present invention.
In this unloading process, after the cooling is completed, the bottom lid 23 of the chamber is opened, the sterilization container-packed solid material 14 is taken out of the chamber, and is transported to the aseptic room side. Thereafter, the solid matter inside the sterilization container stuffed solid matter 14 is taken out, and the sterilization vessel 10 is again subjected to the filling step.

  The inner bottom surface 23d of the bottom lid 23 is a flat surface instead of the protruding structure having the convex portion 23a as described above, while the sterilization container 10 has a raised bottom structure in which a foot portion is provided on its own bottom. May be configured to freely flow in and out from the bottom of the sterilization container 10.

FIG. 10 is a graph showing temperature profiles of the deaeration process, heating process, temperature holding process, and cooling process according to the present invention.
From this graph, according to the solid heat sterilization method of the present invention, the surface temperature of the solid material to be sterilized increases from about 34 ° C. to about 150 ° C. in about 10 seconds, and about 150 ° C. for about 30 seconds. And the temperature drops from about 153 ° C. to about 100 ° C. in about 20 seconds.

  According to the heat sterilization method 100, the sterilization container 10 and the chamber 20 of the solid material, the solid material can be heat sterilized and cooled in a short time.
