Problems to be Solved by the Invention When selecting heat sterilization conditions with a small test machine,
It is necessary to create a test condition that can set a sterilization level equivalent to that of an actual production machine from a relatively small amount of sample liquid. More specifically, the amount of sample liquid that can be used in the test stage is generally limited in many cases,
In a conventional tester, if an attempt is made to select a heat sterilization condition applicable to the actual production process from a small amount of sample liquid, an error may occur in the measured value due to the capacity difference between the practical machine and the test machine. Was not a little. For example, when trying to identify the heat sterilization conditions by introducing the sample liquid into a test machine having an internal volume of 5 liters at a rate of 5 liters per hour, it took one hour to fill the test machine and was attached to this test machine. In order to perform heat sterilization treatment for 10 minutes continuously in the hold tank, it is necessary to introduce 0.83 liters of sample liquid in addition to the above 5 liters. That is, even though the volume of the sample liquid to be heat-sterilized is actually 0.83 liters, it is 5
It is impossible to identify the heat sterilization conditions applicable to the actual production process without preparing an extra sample liquid of 1 liter. In order to approximate the test conditions to the heat sterilization conditions in the actual production machine, if the introduction amount of the sample liquid to be supplied to the test machine with the internal volume of 5 liters is set to 100 liters, the test machine will be filled in 3 minutes. However, if a heat sterilization test is continuously conducted for 10 minutes in this state, an additional 16.7 liters of sample liquid is required in addition to the above 5 liters. In many cases, the usable amount of the sample liquid is generally about 1 to 2 liters, and it is almost impossible to consume such a large amount of the sample liquid as a practical problem. In addition, it causes various obstacles to the accuracy maintenance of the heat sterilization condition set by the test machine and the setting of the heat sterilization condition in the actual production machine.

On the other hand, the second problem associated with the conventional tester is the deterioration of the sample solution due to excessive heating. FIG. 10 is a schematic vertical sectional view of a conventional small-sized tester (20) having a single heating source (21) incorporated therein.
For example, a sample liquid flow path (24) is provided by maintaining a minute gap between a lid (23) and a device wall (22) surrounding a heat transfer device connected to a heating steam introducing chamber or a power supply (27). ) Has been formed. The lid plate (23) is provided with an inlet (25) and an outlet (26) for the sample liquid, that is, the liquid to be heated, corresponding to the channel (24). Reference numeral (7) indicates a temperature sensor. By using this type of tester, the sample liquid introduced into the channel (24) can be heated to a temperature from t 1 to t 2 and a desired sterilization test can be performed. In this heat sterilization method, as shown in FIG. 11, it is possible to use a heat medium having a substantially constant temperature such as steam or a heat transfer device, and various sample liquids including liquid foods due to the simple heating mechanism. Has been evaluated for its practicality as a test heat sterilizer. However, in this heat sterilization method, there is a large difference between the inlet temperature t 1 of the sample solution and the heat medium temperature T, and there is a possibility that the sample solution, which is sensitive to heat, may be damaged or deteriorate. On the other hand, FIG. 12 shows that a low temperature sample liquid having a temperature of t 1 flows from the inlet (25) side to the flow path (2
4) The heat sterilization method is shown in which the temperature of the heat medium changes almost linearly from T 1 to T 2 while flowing into the 4) and flowing out from the outlet (26) while being heated to a high temperature of t 2. . In this method, the temperature gradient of the heating medium, that is, the heating wall surface, is made opposite to the flow direction of the sample liquid, so that the sample liquid inlet (25)
Further, the temperature difference (T 2 −t 1 ) between the heat medium and the sample solution at the outlet (26) is reduced to prevent the sample solution from being deteriorated due to abrupt heating. This heat sterilization device is frequently used for setting heat sterilization conditions for various products including liquid foods, as it provides a heat exchange system suitable for preventing deterioration of the quality of the sample liquid. However, this method also has a capacity limitation, and its improvement has been demanded. The present invention was made with the intent of further improving the known heat sterilization apparatus as described above, and its main purpose is to efficiently apply heat sterilization conditions applicable to an actual production machine from a small amount of sample liquid. It is to provide a small heat sterilizer for testing that can be selected for.

1. A container containing a heat source, a lid plate facing the surface of the container with a minute gap therebetween, and a sample connected to the lid plate at a predetermined interval. In a heat sterilizer having a liquid inflow / outflow port, a minute gap between the surface of the vessel wall of the vessel and the inner surface of the lid plate is configured as a flow path for the sample fluid, and the surface of the vessel wall flows through the sample fluid. A heating and sterilizing device formed in a plurality of heating temperature regions having different surface temperatures along the direction.
