Since the process can be easily switched from the process to the path riser process, the water temperature of the high-temperature water tanks 4C, 4D (the temperature detected by the temperature sensors T3, T4) does not drop, and the water supply of the variable discharge pumps 35C, 35D The water inflow from the high temperature water bypass piping 31A, 31B is continued. Since the warmer 40 can be easily switched to and returned from the path riser 1, there is no loss in the alternating current between the high-temperature water and the heat energy of the hot water.
(Fourth embodiment)

  The warmer 50 also serving as a path riser device according to the fourth embodiment shown in FIG. 4 is the simplest system in which a hot water nozzle group and a recovery water tank are provided on the outlet side of the actual container.

  In FIG. 4, the same path riser 1 described in the first embodiment is also used as a warmer device, and the hot water in the cooling hot water tank 4E on the outlet side of the path riser 1 is sent from the pump 11E to the outlet pipe 13E. However, a bypass pipe 21E that bypasses the outlet pipe 13E to the outlet pipe 13B is installed, and a bypass on-off valve 22E is installed in the bypass pipe 21E, and an on-off valve 23E that shuts off the previous outlet pipe 13E from the branch point of the bypass pipe 21E is installed. The Similarly, the hot water in the cooling hot water tank 4F is sent out from the pump 11F to the outlet pipe 13F. A bypass pipe 21F is installed to bypass the outlet pipe 13F to the outlet pipe 13A. An open / close valve 23F that shuts off the circulation pipe is installed from the branch point of the pipe 21F to the outlet pipe 13F. Further, check valves 24 and 24 for preventing the backflow of the circulating water are provided in the pipes 13A and 13B close to the discharge ports of the pumps 11A and 11B.

  When the warmer function is provided, the pumps 11A, 11B, 11C, and 11D are stopped, the steam supply valves 15A, 15B, 15C, and 5D are closed, the on-off valve 23E on the outlet pipe 13E is closed, and the bypass on-off valve 22E is closed. The hot water in the cooling hot water tank 4E is circulated by the pump 11E. The hot water in the cooling hot water tank 4E is heated by appropriately turning on and off the steam supply valve 15E so that the detected value detected by the temperature sensor T2 matches the set value built in the control device 25. Similarly, the on-off valve 23F on the outlet pipe 13F is closed, the bypass on-off valve 22F is opened, and the hot water in the cooling hot water tank 4F is circulated by the pump 11F.

  The hot water in the cooling hot water tank 4F is heated by appropriately turning on and off the steam supply valve 15F so that the detected value detected by the temperature sensor T6 matches the set value built in the control device 25. As shown in FIG. 8, when the circulating water temperature of the cooling hot water tank 4E and the nozzle group 6E and the cooling hot water tank 4F and the nozzle group 6F is tw, the actual container 7 is gradually warmed by touching the atmosphere in the warmer 50. The temperature rises rapidly due to water spraying from the nozzle groups 6E and 6F from above the cooling hot water tanks 4E and 4F, and the elapsed temperature of the actual container 7 becomes a curve as indicated by Tb.

As described above, according to the fourth embodiment, it is possible to easily switch to the warmer process using the cooling hot water tanks 4E and 4F on the outlet side of the path riser device.
(Fifth embodiment)

  The warmer 60 also serving as a path riser device according to the fifth embodiment shown in FIG. 5 is a combination of a hot water nozzle group provided on the outlet side of the container of the warmer 60 and a recovered water tank. This is a thermal energy recovery system that is diverted to adjust the temperature of circulating water. The component configuration to be added and changed and the warmer action will be described below.

  The pump 11C that feeds the high-temperature water in the high-temperature water tank 4C is driven by an inverter control motor and replaced with the variable discharge pump 35C. Similarly, the pump 11D of the high-temperature water tank 4D is replaced with the variable discharge pump 35D. High temperature water bypass pipes 31E and 31F leading from the outlet pipes 13C and 13D of the variable discharge pumps 35C and 35D to the hot water tanks 4E and 4F for cooling are arranged. The high temperature water bypass pipe 31E has an on-off valve 33E and a high temperature water bypass pipe. An opening / closing valve 33F is provided at 31F. Further, an on-off valve 34E is installed at the outlet pipe 13C ahead of the branch point where the high temperature water bypass pipe 31E is coupled, and an on-off valve 34F is installed at the outlet pipe 13D ahead of the branch point where the high temperature water bypass pipe 31F is joined. .

  The water temperature in the cooling hot water tank 4E is measured by the temperature sensor T2, and the detected water temperature value detected by the temperature sensor T2 is sent to the control device 25. The control device 25 is adjusted so as to match the water temperature setting value built in the same device. The discharge amount of the pump 35C is instructed and controlled. Similarly, the temperature of the cooling hot water tank 4F is measured by the temperature sensor T1, and the detected value detected by the temperature sensor T1 is sent to the control device 25, and the control device 25 performs variable discharge so as to match the set value built in the device. The discharge amount of the quantity pump 35D is instructed and controlled. Since the water temperature of the cooling hot water tank 4E at the time of the path riser treatment is higher than the warmer treatment water temperature, the cold water supply pipe 35E is connected to the high temperature water bypass pipe 31E, and an on-off valve 36E is provided to supply cold water for water temperature adjustment. I am doing so.

  When the warmer processing operation of the warmer 60 is switched from the pastorizer processing of the pastoriser 1 to the warmer processing in which the low temperature container 7 is heated to 30 to 40 ° C., the steam supply valves 15A, 15B, 15C, 15D, 15E, and 15F are turned on. Close the steam heating of all the water tanks, stop the pumps 11A and 11B, close the on-off valves 23E and 23F, and open the bypass on-off valves 22E and 22F, so that the hot water in the cooling hot water tank 4E is pumped 11E, Similarly, the hot water in the cooling hot water tank 4F is circulated to the nozzle group 6F via the pump 11F, the bypass pipe 21F, and the outlet pipe 13F via the bypass pipe 21E and the outlet pipe 13E.

  When the water temperature is higher than the set value, the on-off valve 36E on the cold water supply pipe 35E connected to the high temperature water bypass pipe 31E is opened to adjust the water temperature of the cooling hot water tank 4E, and the cooling hot water tank 4E has cold water. And the water temperature is adjusted via the temperature sensor T2. When the water temperature in the cooling hot water tank 4E reaches the set value, the on-off valve 36E is closed. In the subsequent water temperature adjustment, the bypass on-off valve 22E is opened and the high-temperature water in the high-temperature water tank 4C discharged from the variable discharge pump 35C from the high-temperature water bypass pipe 31E is sent to the cooling hot water tank 4E and detected by the temperature sensor T2. The discharge amount of the variable discharge amount pump 35C is controlled so that the temperature becomes a set value stored in the control device 25. Further, the water temperature of the cooling hot water tank 4F is adjusted by opening the on-off valve 33F and sending the high temperature water in the high temperature water tank 4D discharged from the variable discharge pump 35D from the high temperature water bypass pipe 31F to the cooling hot water tank 4F. The discharge amount of the variable discharge amount pump 35D is controlled so that the temperature detected by the sensor T1 becomes the set value stored in the control device 25.

  When the water temperature of the high temperature water tank 4C (detected temperature of the temperature sensor T3) falls to the set water temperature in the cooling water tank 4E, the water supply of the variable discharge pump 35C is set to 0 (zero), the on-off valve 33E is closed, and high temperature water is supplied. Water inflow from the bypass pipe 31E is stopped, circulation from the cooling hot water tank 4E to the nozzle group 6E is performed by the pump 11E, and the steam supply valve 15E can be opened and closed to adjust the water temperature in the cooling hot water tank 4E. And the steam supply valve 15E shifts to ON / OFF control. Similarly, when the water temperature of the high temperature water tank 4D (detected temperature of the temperature sensor T4) falls to the set water temperature in the cooling water tank 4F, the water supply of the variable discharge pump 35D is set to 0 (zero), and the open / close valve 33F is closed. The water flow from the hot water bypass pipe 31F is stopped, the circulation from the cooling hot water tank 4F to the nozzle group 6F is performed by the pump 11F, and the steam supply valve 15F can be opened and closed to adjust the water temperature in the cooling hot water tank 4F. The process proceeds to on / off control of the temperature sensor T1 and the steam supply valve 15F.

The heat energy saving of the warmer 60 is the same as that of the warmer 30 of the second embodiment. That is, the temperature difference between the circulating water temperature of the high-temperature water tanks 4C and 4D during the path riser treatment and the circulating water temperature of the cooling hot water tanks 4E and 4F during the warmer treatment is Ac and Ad hatched in FIG. And the amount of water in the high-temperature water tanks 4C and 4D is an amount of heat that can be used for temperature adjustment of the cooling water tanks 4E and 4F. If the amount of water combined with the hot water tanks 4E and 4F for cooling is the same as the amount of water combined with the hot water tanks 4A and 4B, the calculation example in the case of the warmer 30 of the second embodiment can be applied as it is.
(Sixth embodiment)

  A warmer 70 that also serves as a path riser device according to the sixth embodiment shown in FIG. 6 adjusts the temperature of high-temperature water stored when the path riser 1 is operated to the state of the path riser 1 as it is. This is a thermal energy recovery method that is diverted to adjust the temperature of the circulating water in the recovery water tank and the group of hot water nozzles provided on the outlet side, and at the same time, it is a method that can be easily switched from the warmer 70 to the path riser 1. The component structure to be added and changed and the warmer action will be described below. Since the component configuration of this embodiment is exactly the same as that of the fifth embodiment, the description of the configuration is omitted, and the warmer action will be described below.

  The action of the warmer 70 of the sixth embodiment differs from the action of the warmer 60 of the fifth embodiment in that the steam supply valve 15C for heating the high temperature water in the high temperature water tank 4C and the high temperature water in the high temperature water tank 4D. The steam supply valve 15D that heats the steam is opened and closed by a control command from the control device 25, and the temperature of the hot water in the hot water tanks 4C and 4D is controlled so as to maintain the temperature at the time of operation of the path riser 1. Since the process can be easily switched from the process to the path riser process, the water temperature of the high-temperature water tanks 4C and 4D (the temperature detected by the temperature sensors T3 and T4) does not drop, and the water supply of the variable discharge pumps 35C and 35D The water inflow from the high temperature water bypass pipes 31E and 31F is continued. Since the warmer 70 can be easily switched to and returned from the path riser 1, there is no loss in the exchange of heat energy between the high-temperature water and the hot water.
