[Prior art] As a means of sterilizing foods, pharmaceuticals, etc., the items to be sterilized are filled into a container such as a bag and sealed, and then placed in a retort or continuously transferred in a high-pressure tank and kept at high temperature for a predetermined period of time. Heating under high pressure is known from JP-A-64-51069 and other publications. [Problems to be Solved by the Invention] However, in the conventional method, the tank itself is held at high pressure and high temperature, and the contents to be sterilized are heated from the outside of the container. Problems include the occurrence of a whitening phenomenon, the inability to quickly and evenly heat the object to be sterilized due to the shape of the bag or container, and the difficulty in controlling the temperature of the object to be sterilized, as well as poor thermal efficiency and complicated configuration. There is a point. In view of the current situation, it is an object of the present invention to provide a sterilizer that can easily control the temperature of heat sterilization of objects to be sterilized, can heat sterilize without degrading quality, and has a sterilization method with high thermal efficiency. That is. [Means for Solving the Problem] In order to achieve the above-mentioned object, the method of the present invention involves heating the object to be sterilized to a sterilization temperature, immediately filling and sealing the container in a high-pressure tank, and then holding the object for a predetermined sterilization time. The gist of this method is to perform heat sterilization in step 2, cool it, and then take it out from the high-pressure tank. The present invention also provides a high-temperature heating device for heating the raw material to a sterilization temperature, a high-pressure tank equipped with a cooling tank in the F section, and a gas phase section and a cooling tank in the high-pressure tank. an intermittent conveyance device for containers stretched so as to sequentially circulate; a filling device for filling the container of the gas phase conveyance device with the raw material heated by the high-temperature heating device; and a sealing opening of the filled container. The present invention is comprised of a sealing device, a container feeding device for supplying containers to a conveying device in front of the filling device, and a container unloading device for taking out 2 tons of heat-sterilized filled containers from the conveying device and rearranging them. That is. The objects to be sterilized in the present invention are fluid foods and liquids. Refers to fluid pharmaceuticals such as blood for transfusion, which are filled into plastic bags or containers such as polyethylene, sealed, and heat sterilized. [Operation] In the method of the present invention, the object to be sterilized is directly heated to a high temperature to the sterilization temperature, and the heated and roasted object is immediately filled and sealed in a deaerated container in a high-pressure tank. After heat sterilization is performed by maintaining the product in a high-temperature heating state for a predetermined period of time required for sterilization, the shell is cooled and taken out from the high-pressure tank. Furthermore, in the apparatus of the present invention, a fluid material to be sterilized is heated to a predetermined sterilization temperature using a high-temperature heating device, and is then supplied to a container supply device 1τ, 1 and a conveyance device in the gas phase section of a high-pressure tank, and then transferred. After filling the container with a filling device, the container is sealed with a filling and sealing device, and the gas phase is intermittently transferred for a predetermined sterilization period to perform heat sterilization, and then transferred to a cooling tank for agitation. There is a container removal device that takes the container out of the high-pressure tank. [Example] A detailed example of the IJ method and apparatus of the present invention will be described. Materials to be sterilized such as fluid foods, blood, and fluid medicines such as infusions are transferred from a raw material tank 1 to a heat exchange device or other high temperature device. Sterilization temperature 1 adapted to the object to be sterilized by passing through the heating device 2!
: It is constructed so that it can be heated to a high temperature of 110 to 140°C and immediately transferred via an insulating pipe or the like to a filling device 4 in a high-pressure tank 3 pressurized to 1°2 to 2.0 kg. A cooling tank 5 is provided at the bottom of the high-pressure tank 3, and a conveying device 7, which accommodates a container for filling and has a retainer 6 attached thereto, connects the gas phase section of the F section and the cooling tank 5 at the bottom. The structure is strung so that it circulates and is driven intermittently.
Further, above the starting end of the conveying device h7 in the gas phase section, a container supply device 8 for supplying containers to the retainer 6 and a container take-out device 9 for taking out the filled containers from the retainer 6 are installed extensively. Therefore, the filling nozzle of the filling device 4 is connected to the container feeding device 8.
A sealing device 10 is further installed in front of the filling device 4 to fill the containers in the retainer 6 with objects to be sterilized in a high-temperature heated state when the conveying device 7 is intermittently stopped. It is configured to seal the opening of the container filled with the object to be sterilized. The container filled with the object to be sterilized in this way is transferred to the transport device 7.
After being intermittently transferred to the gas phase section for a predetermined period of time and heat sterilized by the heat of the object to be sterilized, it is intermittently transferred to the cooling tank 5 provided at the bottom of the high pressure tank 3 to be cooled, and then transferred to the gas phase section again. Then, during the intermittent stop F, the container is taken out from the retainer 6 to the outside of the high-pressure tank 3 by the container take-out device 9, and sterilization is completed. The heating temperature of the high temperature heating device 2, the pressure of the high pressure tank 3,
The intermittent transfer speed of the conveying device 7 is configured to be adjustable according to the type and amount of the object to be sterilized, the type of container, the sterilization time, etc. For example, in the case of an object to be sterilized that can be sterilized at 118° C. in 4 minutes, The object to be sterilized is heated to 120℃, which is slightly higher than the sterilization temperature.
It is heated in a high-temperature heating device 2, then filled in a bag made of polyethylene or the like in a high-pressure tank 3 of 1.3 kg/a (sealed) and conveyed intermittently for 4 to 5 minutes in the gas phase, resulting in a temperature of 118°C. Since the prescribed heat sterilization process is completed, it is necessary to transport it to the cooling tank 5, cool it, and then take it out from the high-pressure tank 3. In the figure, 11 is a cooling water circulation pump, and 12 is a cooling device. When reliably preventing air or other contamination, such as with blood for transfusion, use a sealed container with the filling part of these containers sealed, and open the filling part in a high-pressure tank to sterilize the container. A container filling section cutting device is provided in front of the filling device 4 so that the container can be filled with objects, and the sealed container is further supplied to the retainer 6 of the conveying device 7 with the filling section facing downward, and after cutting the filling section, the container is conveyed. After rotating the device 7 by 18.0 degrees so that the filling part of the container faces upward, filling the container with the filling device 4 and sealing the filling part with the sealing device 10, the conveying device 7 was turned over 180 degrees and sealed again. It is preferable to provide a container reversing device in the transport device 7 so that the container can be transported with the filling part facing downward.Furthermore, the container loading/unloading means in the container feeding device 8 and the container unloading device 9 reduce the pressure inside the high pressure tank 3. Kotona〈Conventionally known methods, such as the
This method uses known methods such as those disclosed in Japanese Patent Laid-open No. 43350 and Japanese Patent Application Laid-Open No. 64-51069. [Effects of the Invention] The method of the present invention involves sterilizing a fluid material to be sterilized by directly heating it to a high temperature, filling it in a container in a high-pressure tank, and then keeping it in the high-pressure tank for a predetermined sterilization time. Compared to the conventional method of heating the inside of a high-temperature tank to the sterilization temperature, thermal efficiency can be significantly improved, and at the same time, the sterilization temperature can be easily controlled, and the objects to be sterilized are evenly brought to the sterilization temperature regardless of the container. It can be heated, does not change the quality of the container, and can efficiently perform heat sterilization treatment at low cost. Furthermore, since the apparatus of the present invention does not require a heating means inside the high-pressure tank, the structure and equipment of the high-pressure tank can be simplified, and the high-temperature heating device installed outside the high-pressure tank can directly heat the objects to be sterilized. Temperature control is easy, and the structure of the sterilizer itself is simple and can be manufactured at low cost.
