Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration example of a sterilization strength measurement output system according to an embodiment of the present invention. As shown in FIG. 1, the sterilization strength measurement output system includes various information such as UHT 10, balance tank 21, INV (inverter rotary pump) 22, holding tube 23, filling machine 24, and F ₀ value calculation. an information processing unit 50 for processing, and an information output unit 51 for outputting various information such as the F ₀ value. Although not shown in FIG. 1, the information processing unit 50 is connected to each unit of the sterilization strength measurement output system through signal lines, and acquires data necessary for information processing in this example. .

  The sterilization strength measurement output system balances the liquid feed line that feeds the liquid to be processed from the preparation tank to the filling machine 24 and the recovered liquid (return liquid) collected from the liquid feed line before flowing into the filling machine 24. And a recovery liquid line for returning to the tank 21. The liquid feeding line and the recovery liquid line are configured by pipes, for example.

  The sterilization strength measurement output system includes a liquid level indicator alarm meter 31, an electromagnetic flow meter 32, a sterilization temperature indication controller 33, a holding outlet sterilization temperature recorder 34, and a filling machine liquid supply temperature record on the liquid supply line. A total 35, a filling machine liquid feeding temperature controller 36, a back pressure valve 37, and a filling liquid feeding valve 38 are provided.

  Further, the sterilization strength measurement output system includes a return valve 41, a filling return temperature alarm meter 42, a cooling plate outlet temperature controller 43, a back pressure valve 44, and a recovery valve 45 on the recovery liquid line. Yes.

  The UHT 10 includes a return liquid cooling unit 11 that cools the return liquid, a filling liquid cooling unit 12 that cools the filling liquid, and a filling liquid sterilization unit 13 that heats the filling liquid for sterilization.

Next, the operation of the sterilization strength measurement output system will be described.
In the sterilization strength measurement output system, the liquid from the preparation tank is stored in the balance tank 21, and the stored liquid is sent from the balance tank 21 to the inverter rotary pump 22 side. The liquid level indicator / alarm meter 31 monitors the flow rate of the liquid being fed from the balance tank 21, and in order to keep the flow rate within a certain range, the liquid level indicating alarm meter 31 is a liquid feed pump for feeding the balance tank 21 to the balance tank 21. Perform on / off control. The flow rate adjusted by the liquid level indicator / alarm meter 31 is determined by selecting a snap switch prepared in advance for each size of the bottle filled with the liquid. In addition, according to selection of a snap switch, the flow volume (namely, the output of the liquid feed pump of a preparation tank) adjusted by the liquid level indication alarm meter 31 changes.

  The inverter rotary pump 22 is always turned on during automatic operation, and sends the liquid sent from the balance tank 21 toward the filling liquid sterilization unit 13 of the UHT 10. The flow rate of the liquid fed from the inverter rotary pump 22 toward the filling liquid sterilization unit 13 is measured by the electromagnetic flow meter 32, and the measured value is notified to the information processing unit 50.

  The filling liquid sterilizing unit 13 heats the liquid flowing in from the inverter rotary pump 22 side until it passes through the holding tube 23 side. Then, the heated liquid flows into the holding tube 23. The sterilization temperature indicating controller 33 is a temperature sensor that measures the temperature of the liquid at the inlet of the holding tube 23, and outputs the measured value to the information processing unit 50. The sterilization temperature indicating controller 33 controls the sterilization temperature (controls the amount of steam for heating in the filling liquid sterilization unit 13) according to the measured temperature. Further, the sterilization temperature indicating controller 33 controls the return valve 41 and the filling liquid feeding valve 38 according to whether or not the measured temperature is within a specified range. Furthermore, when the measured temperature is out of the specified range, the sterilization temperature indicating controller 33 issues an alarm for notifying that effect.

  The holding tube 23 is a tube for storing the liquid heated in the filling liquid sterilization unit 13 for a predetermined period in order to sterilize the liquid to be processed. Accordingly, the holding tube 23 has a capacity that can be stored for a predetermined period for liquid sterilization.

  The temperature of the liquid flowing out of the holding tube 23 is measured by the holding outlet sterilization temperature recorder 34, and the measured value is output to the information processing unit 50. The holding outlet sterilization temperature recorder 34 is a temperature sensor that measures the temperature of the liquid at the outlet of the holding tube 23.

  The liquid to be treated is measured by the holding outlet sterilization temperature recorder 34 and then cooled by the filling liquid cooling unit 12. When the filling liquid cooling unit 12 flows out, the temperature of the liquid to be processed is measured by the filling machine liquid feeding temperature recorder 35. In addition, when the measured value of the temperature measured by the filling machine liquid feeding temperature recorder 35 is outside the predetermined range, the filling liquid temperature controller 36 controls the filling liquid temperature (filling liquid cooling unit 12). Control the amount of steam for cooling in). In addition, when the measured temperature is outside the specified range, the filling machine liquid feeding temperature controller 36 issues an alarm for notifying that effect.

  The liquid that has flowed out of the filling liquid cooling unit 12 passes through the back pressure valve 37, and in the normal operation, passes through the filling liquid feeding valve 38 and flows into the filling machine 24. The filling machine 24 fills the stored liquid into a liquid container such as a PET bottle. During normal operation, the return valve 41 and the filling liquid feeding valve 38 are on the filling side.

  The condition that the return valve 41 and the filling liquid feeding valve 38 are on the filling side is that the filling machine 24 requires liquid feeding (when the amount of liquid in the filling machine 24 is lower than the upper limit due to liquid level control). ) And the temperature indicated by the sterilization temperature indicating controller 33 is within the set temperature.

  On the other hand, the condition that the return valve 41 and the filling liquid feeding valve 38 are on the return side is that the filling machine 24 refuses the liquid feeding (the liquid amount in the filling machine 24 is more than the upper limit due to the liquid level control (full). Or the temperature indicated by the sterilization temperature indicating controller 33 is outside the set temperature.

  If the return valve 41 and the filling liquid supply valve 38 are on the return side, the liquid that has passed through the back pressure valve 37 passes through the return valve 41 and is supplied to the return liquid cooling unit 11. The return liquid that has passed through the return valve 41 is temperature-measured by a filling return temperature alarm meter 42. When the measured temperature is outside the specified temperature, the filling return temperature alarm meter 42 issues an alarm for notifying that effect.

  The return liquid cooled by the return liquid cooling unit 11 is measured by the cooling plate outlet temperature regulator 43, passes through the back pressure valve 44 and the recovery valve 45, and is returned to the balance tank 21. The cooling plate outlet temperature regulator 43 controls the cooling temperature (controls the cooling water in the return liquid cooling unit 11) according to the measured temperature. Further, when the measured temperature is outside the specified range, the cooling plate outlet temperature adjuster 43 issues an alarm for notifying that effect.

Next, F ₀ value output processing of the information processing unit 50 in the sterilization strength measurement output system will be described.
FIG. 2 is a flowchart illustrating an example of the F ₀ value output process. The F ₀ value output process is repeatedly executed at regular time intervals (for example, every second, every 10 seconds, every minute, etc.) when the sterilization strength measurement output system is in an operating state.

In the F ₀ value output process, the information processing unit 50 acquires the measurement value of each measurement sensor included in the drinking water manufacturing system (step S11), and calculates the F ₀ value based on the acquired measurement value (step S12). ). Note that the F ₀ value is given by the following equation.

In Formula 1, F ₀ is the sterilization strength (F ₀ value), “V” is the capacity (L) of the holding tube 23, “L” is the flow rate (L / min), and “T” is the sterilization. It is a reference temperature, “Ti” is a sterilization temperature, and “Z” is a constant (Z value) determined by a sterilization reference temperature or an appropriate holding time (sterilization reference time). This Z value refers to the temperature required to reduce the heat kill time of a particular bacterium to 1/10.

In general, first, the range of F ₀ is determined according to the pH value of the liquid to be treated, and the Z value is determined. Next, the minimum temperature is calculated from the holding capacity on the equipment, etc., and the sterilization reference temperature “T” is determined taking into account variations in the sterilization effect in the sterilizer (holding tube 23). That is, a Z value and a sterilization reference temperature “T” that can ensure an appropriate F ₀ range are determined in advance.

Specifically, for example, assuming that the liquid to be treated is a soft drink and the pH value is 4 or more, first, F ₀ is set to 4 or more, and thereby the Z value is determined to be 10. Next, assuming that the holding tube capacity “V” is 100 (L), the filling speed is 400 (bpm), and the product internal volume is 500 (ml), 100 / (0.5 · 400) = 0.5 minutes = 30 seconds. Then, for example, the minimum temperature is 130.2 degrees by a predetermined temperature calculation formula for calculating the minimum temperature at which F ₀ = 4 can be secured in 30 seconds (not shown because it is a general calculation formula by sterilization engineering). (Celsius (the same applies below)). At this time, F ₀ = 4.064. If the variation in the sterilization effect in the sterilizer is ± 1.5 degrees, the sterilization reference temperature “T” is determined to be “131.7 ± 1.5” degrees. In addition, since the relationship between the sterilization reference temperature and the sterilization reference time when the Z value is determined as the value of the Z value according to the pH value of the liquid to be treated is defined in the Food Sanitation Law, the relationship Each value may be fixed based on the above.

  As described above, for example, when the Z value is “10”, the expression 1 becomes the following expression. When the Z value is “10”, the sterilization reference temperature “T” is 121.1 degrees (specifically, “121.1 ± 1.1” degrees: the minimum temperature is 120 degrees, sterilization in a sterilizer. The effect variation is determined to be ± 1.1 degrees. In this case, the sterilization reference time is 4 minutes or more.

  In this example, the Z value is set to “10”, but when the pH value of the liquid to be processed is less than 4.0, the Z value is set to “5”. In this case, the sterilization reference temperature “T” is 65 degrees and the sterilization reference time is 10 minutes or equivalent or more. When the pH value of the liquid to be treated is less than 4.0 to 4.6, the Z value is set to “8”. In this case, the sterilization reference temperature “T” is 85 ° C., and the sterilization reference time is 30 minutes or equivalent or more.

In step S <b> 12, the information processing section 50 determines the sterilization temperature “Ti” measured by the holding outlet sterilization temperature recorder 34 and the liquid sent from the balance tank 21 measured by the liquid level indicator alarm meter 31. The sterilization strength “F ₀ ” is calculated by substituting the flow velocity “L” calculated based on the flow rate and the volume “V”, which is a fixed value registered in advance, into Equation 2 above. In this example, the information processing unit 50 calculates the flow rate “V / L” and then substitutes it into Expression 2.

When the sterilization strength “F ₀ ” is calculated, the information processing unit 50 calculates the calculated F ₀ value, the sterilization temperature “Ti” measured by the holding outlet sterilization temperature recorder 34, and the calculated flow rate “V / L”. And sterilization intensity information in which the current time is associated (step S13).

Next, if the sterilization strength “F ₀ ” calculated in step S12 is not equal to or higher than a predetermined value that can guarantee the quality of the liquid (N in step S14), the information processing unit 50 generates the sterilization strength generated in step S13. Insufficient sterilization strength information indicating that the sterilization strength is insufficient to a quality guaranteeable value is added to the information (step S15).

If the sterilization strength “F ₀ ” calculated in step S12 is greater than or equal to a predetermined value that can guarantee the quality of the liquid (Y in step S14), or if sterilization strength deficiency information is added in step S15, the information The processing unit 50 accumulates sterilization strength history information including sterilization strength information (step S16). In addition, when the sterilization strength shortage information is added in step S15, the sterilization strength shortage information is included in the sterilization strength history information.

  Then, for example, as illustrated in FIG. 3, the information processing unit 50 displays the accumulated sterilization strength history information on the display screen of the information output unit 51 (Step S <b> 17). Here, for example, sterilization strength history information accumulated during a predetermined period in the past is displayed on the screen.

As shown in FIG. 3, the sterilization intensity history information outputted bactericidal strength "F _0" calculated in step S12, time calculated bactericidal strength "F _0" (measurement time), bactericidal strength "F ₀ The temperature (measured temperature) used to calculate “,” the flow rate (measured flow rate) used to calculate the sterilization strength “F ₀ ”, and the sterilization strength deficiency information are included. For example, the sterilization strength history information is always displayed on the display screen of the information output unit 51, and new history information is additionally displayed every time the sterilization strength “F ₀ ” is calculated.

  Note that the method of outputting the sterilization strength history information may not be displayed on the screen, and may be output (printed) on, for example, paper. In the above example, the sterilization strength history information is updated and output every predetermined period, but the sterilization strength history information is output in response to an instruction operation by a system monitor or the like. Also good.

Further, the output format of the sterilization strength history information is not limited to the table format as shown in FIG. 3, but may be a graph format as shown in FIG. In Figure 4, measured on the horizontal axis time, the calculated value of the sterilization intensity on the vertical axis "F _0" has been taken, a new history information (measurement time and sterilization intensity whenever the sterilization intensity "F _0" is calculated The points indicated by and will be displayed. With the display format shown in FIG. 4, it becomes possible to immediately know the time when the sterilization strength “F ₀ ” takes a value whose quality cannot be guaranteed.

Note that the sterilization strength deficiency information may not be added to other information, and may be represented by a graph as shown in FIG. 4, for example, the display color or size of the corresponding F ₀ value, etc. It may be made possible to recognize by changing.

  As described above, according to the above-described embodiment, the storage period (capacity “L”) in which the liquid heated in the filling liquid sterilization unit 13 is stored in the holding tube 23, and the filling liquid sterilization unit 13 Since the sterilization strength is calculated based on the sterilization temperature indicating the temperature of the heated liquid and the sterilization strength history information including the calculation result is output, the quality of the liquid is determined by the output sterilization strength history information. It can be confirmed accurately and quickly whether the level is assured.
