Description

  The present invention relates to equipment for pasteurization of foodstuffs and a method for operating this pasteurization equipment.

  Pasteurization of foodstuffs is currently commonly used to minimize the amount of microorganisms in foodstuffs. In particular, the shelf life of foodstuffs can be extended in this way, and the possible health risks arising from, for example, harmful bacteria or spoiled foods caused by microorganisms Problems can be prevented.

  A widely used method for pasteurizing foodstuffs is to fill the container with the foodstuff, seal the container, and then pour the temperature-conditioned processing liquid onto the container Including that. For these purposes, so-called tunnel pasteurizers are frequently used in which containers filled with foodstuffs are transported through several temperature treatment zones. . Such tunnel pasteurizers are commonly used, for example, to pasteurize beverages filled in bottles or cans.

  In tunnel pasteurizers, containers filled with foodstuffs are usually first in one or more heating zones with a treatment liquid having a moderate temperature to allow gentle heating of the foodstuffs. Is processed. For this purpose, the container may be continuously processed in several heating zones with a processing liquid having an increasing temperature level. After this, a treatment liquid having a temperature level high enough to kill the microorganisms is poured onto a container filled with foodstuffs in one or more pasteurization zones. The container must then be cooled, most often in one or several cooling zones, to prevent deterioration of the food product in the container.

  In such a pasteurization process, a treatment liquid having a low temperature level and a treatment liquid having a high temperature level must be provided. It is known in the art to use treatment liquid recovery for heating or cooling within the treatment zone. Furthermore, it is also known in the art to use heat pumps to transfer thermal energy from a treatment liquid having a low temperature level to a treatment liquid having a high temperature level.

  For example, U.S. Patent No. 6,057,051 discloses a tunnel pasteurizer, in which the recovery liquid is sent to the cooling zone after it has passed through the heating zone, and vice versa. In addition to this, the pasteurization line in Patent Document 1 discloses a heat pump, and this heat pump transfers thermal energy from a treatment liquid having a low temperature level to a treatment liquid having a high temperature level in the pasteurization line. Used to do.

  In principle, heat pumps are the most energy efficient means for providing thermal energy in a pasteurization line that requires both heating and cooling procedures. However, mainly as a result of the changing operating conditions of the pasteurization line, it is impossible for the energy efficiency of the heat pump to be utilized to the highest extent possible, as in the heat pump disclosed in US Pat. There is a further need to optimize energy management of pasteurization equipment.

German Patent Application Publication No. 10201131398 (A1)

  It is an object of the present invention to meet this need and to improve the pasteurization equipment and to improve the energy efficiency of the pasteurization equipment and an improved method for operating the pasteurization equipment. Is to provide.

  This object is achieved by the method and pasteurization equipment described in the claims.

  A method for operating a pasteurization facility is provided. The pasteurization facility includes a first pasteurization line and at least a second pasteurization line. Within each of the first and second pasteurization lines, a sealed container filled with foodstuff is passed through at least one heating zone and then passed through at least one cooling zone. . In each of the first and second pasteurization lines, the food product is heated in at least one respective heating zone by metering a temperature-controlled treatment liquid onto the container, and then In each of the first and second pasteurization lines, the food product is cooled in at least one respective cooling zone by metering a temperature conditioned treatment liquid into the container. Further, the heating liquid is heated by the heating means of the heat pump, and the cooling liquid is cooled by the cooling means of the heat pump.

  Based on the heating requirements for the first and second pasteurization lines, the heated heating liquid from the heating means of the heat pump has a high temperature level of the first pasteurization line by the first heating heat exchanger. A treatment liquid used to heat the treatment liquid and / or the heated liquid from the heating means of the heat pump has a high temperature level in the second pasteurization line by the second heating heat exchanger. Used to heat. In addition, based on the cooling requirements for the first and second pasteurization lines, the cooled coolant from the heat pump cooling means is passed through the first pasteurization line by the first cooling heat exchanger. Used to cool the processing liquid having a low temperature level and / or the cooled cooling liquid from the cooling means of the heat pump is cooled by the second cooling heat exchanger in the low temperature of the second pasteurization line. Used to cool the treatment liquid having a level.

  In order to heat the treatment liquid having a high temperature level in the first and / or second pasteurization line, the heated heating liquid from the heating means of the heat pump is used as the first and / or second heating heat exchanger. At the same time, the processing liquid of the first and / or second pasteurization line is transferred through the secondary side of the first and / or second heating heat exchanger. In order to cool the processing liquid having a low temperature level in the first and / or second pasteurization line, the cooled cooling liquid from the cooling means of the heat pump is used as the first and / or second cooling heat exchanger. At the same time, the processing liquid of the first and / or second pasteurization line is transferred through the secondary side of the first and / or second cooling heat exchangers. The heating liquid is heated by transferring the heating liquid through the heating means of the operated heat pump, and the cooling liquid is cooled by transferring the heating liquid through the cooling means of the operated heat pump.

  By this method, the heated heating liquid and the cooled cooling liquid can be used according to the heating and cooling requirements of the first pasteurization line and at least the second pasteurization line, respectively. Thus, the energy efficiency of pasteurization equipment can be greatly increased. Such varying heating and cooling requirements may arise as a result of, for example, different pasteurization temperatures or different target cooling temperatures required for individual food products. Large differences in heating and cooling requirements also result when starting a pasteurization line or when completing the pasteurization of a charge, for example for batch changes or for maintenance work . At the beginning of the pasteurization line, a large number of containers must first be heated, and at the same time, zero or only a few containers must be cooled, so the pasteurization line has a large heating demand and a small amount. Or zero cooling requirements. At the completion of the pasteurization line cycle and when the pasteurization line is shut down, a large amount of cooling requirements will arise, while at the end of the cycle many containers must be finally cooled and heated at the same time. Since no new containers are to be inserted into the pasteurization line, heating requirements are reduced. Differences in requirements may also arise as a result of, for example, the initial temperature of the container inserted into the pasteurization line. The actual heating and cooling requirements of the pasteurization line can be measured, for example, by placing temperature sensors at appropriate locations to measure and monitor the temperature of the processing liquid in the first and second pasteurization lines. Can be done.

  The heated heating fluid will be used to heat the processing fluid in the pasteurization line with high heating requirements. On the other hand, the cooled coolant will be used to cool the treatment liquid in a pasteurization line with high cooling requirements. Thus, by using this method, for example, by cooling the processing liquid of a pasteurization line having a high actual cooling requirement and by heating the processing liquid of a pasteurization line having a high heating requirement, By transferring excess thermal energy to the sterilization line, it is further possible to efficiently transfer thermal energy between the pasteurization lines. Thus, such transfer of thermal energy between pasteurization lines can be realized without mixing the pasteurization line treatment liquid.

  Finally, this method allows continuous and energy efficient operation of the heat pump at high performance levels because both the heating and cooling capabilities of the heat pump can be utilized to a very high degree. . This allows the heat pump to operate in the region of very high coefficient of operation (COP) for heating and cooling. Those skilled in the art will also recognize that this method operates three or more pasteurization lines, for example, by heating and / or cooling treatment liquids such as the third pasteurization line, the fourth pasteurization line, etc. It will be understood that it can of course be applied. The operation of the additional pasteurization line will be included in the method in the same manner as the operation of the first and second pasteurization lines.

  One embodiment of this method is based on heating requirements for the first and second pasteurization lines, and heated heating fluid from the heating means of the heat pump is pumped into the upper region of the heating fluid buffer tank, and It would include that the heated liquid is returned from the lower region of the heated liquid buffer tank into the heating from the heating means of the heat pump.

  By these measures, the energy efficiency of the operation of the pasteurization facility can be further increased. For example, if the heating requirement is low or absent in a pasteurization line, the heated heating fluid can be used to increase the overall temperature level in the heating fluid buffer tank. Thus, any excess thermal energy generated by the heat pump can be temporarily stored in the heated liquid buffer tank for subsequent use without being wasted. It would be preferred that the heated liquid buffer tank be operated as a layered storage tank, and for the temperature sensor to monitor the temperature levels of different levels of heated liquid in the heated liquid buffer tank. used.

  Yet another embodiment is that the heating liquid has a high temperature level of the first pasteurization line and / or the second pasteurization line, for example based on the heating requirements for the first and second pasteurization lines. In order to heat the treatment liquid, it is fed into the first heating heat exchanger and / or the second heating heat exchanger from the upper region of the heating liquid buffer tank and into the first heat exchanger and / or It would include that the heating fluid from the second heat exchanger is returned into the lower region of the heating fluid buffer tank.

  Such a procedure is particularly advantageous when high heating requirements are present in the first and / or second pasteurization lines. In this way, the heating capacity of the heat pump is utilized to a higher degree, and the use of additional heating means with lower energy efficiency can be limited at least during operation of the pasteurization facility. .

  Preferably, the heated heating liquid from the heating means passes through the hollow profile body, having an opening in a portion of the peripheral surface of the hollow profile body, into the heating liquid buffer tank. And the hollow profile body is such that all the openings face towards the upper end of the heated liquid buffer tank and the heated liquid from the heated liquid buffer tank is in its other hollow profile. Disposed in the upper region of the heated liquid buffer tank so as to be fed back into the heating means via another hollow profile body having an opening in a part of the peripheral surface of the body, and this Another hollow profile body with all openings facing towards the lower end of the heated liquid buffer tank The heating liquid buffer tank is disposed in the lower region.

  By these measures, the heated liquid buffer tank may be operated as a stratified storage tank in a very efficient manner. The heating liquid heated by the heating means of the heat pump has a relatively high temperature level. Upon charging, the heated heating liquid having a high temperature level can be guided or pushed towards the upper end of the heating liquid buffer tank by a hollow profile body located in the upper region. Yes, thus moving a layer of heating liquid having a moderate temperature level towards the lower region of the heating liquid buffer tank. On the other hand, the heating liquid with a relatively low temperature level, layered or stratified in the lower region of the heating liquid buffer tank, can be transported to the heating means of the heat pump via another hollow profile body It is. In this way, unnecessary mixing of heating liquid layers having different temperature levels in the heating liquid buffer tank and thus unnecessary temperature leveling can be prevented. In the following, this means that a stable temperature level of the heating liquid in the upper and lower areas of the heating liquid buffer tank is provided for a long time when charging the heating liquid buffer tank with thermal energy. Allows the operation of the heat pump at the highest possible COP for heating.

  Further, based on the heating requirements for the first and second pasteurization lines and based on the temperature of the heating liquid in the heating liquid buffer tank, the heating liquid from the upper region of the heating liquid buffer tank And is fed into the first heating heat exchanger and / or the second heating heat exchanger and heated from the first heating heat exchanger and / or the second heating heat exchanger It may be expedient to be returned to the lower region of the heated liquid buffer tank via another hollow profile body.

  In this way, the heated liquid buffer tank can be further efficiently operated as a layered buffer tank during removal. Using such a layered liquid buffer tank, a stable long-time operation of the heat pump at a high COP is enabled.

  Independently, one embodiment of the present invention is based on the cooling requirements for the first and second pasteurization lines, and the cooled coolant from the heat pump cooling means is placed in the lower region of the coolant buffer tank. Pumped and coolant will include returning from the upper region of the coolant buffer tank into the cooling means of the heat pump.

  This cooled coolant can thus be used to reduce the overall temperature level in the coolant buffer tank, and a low or no cooling requirement will be present in the pasteurization line. Even when present in any of the above, the cooling capacity of the heat pump can be fully used. Preferably, the coolant buffer tank may be further operated as a stratified storage tank and temperature sensors are used to monitor the coolant temperature level at various heights within the coolant buffer tank. Is done.

  Yet another embodiment is that the coolant has a low temperature level of the first pasteurization line and / or the second pasteurization line, for example based on cooling requirements for the first and second pasteurization lines. In order to cool the processing liquid, it is fed into the first cooling heat exchanger and / or the second cooling heat exchanger from the lower region of the cooling liquid buffer tank and into the first cooling heat exchanger and / or Or it may include that the coolant from the second cooling heat exchanger is returned into the upper region of the coolant buffer tank.

  Such a procedure is particularly advantageous when high cooling requirements are present in the first and / or second pasteurization lines. By this measure, the cooling capacity of the heat pump can be utilized to a higher degree and the use of additional cooling means with lower energy efficiency is limited at least during the operation of the pasteurization facility. It is possible.

  Preferably, the cooled coolant from the cooling means of the heat pump is pumped into the coolant buffer tank via the hollow profile body having an opening in a portion of the peripheral surface of the hollow profile body, and The hollow profile body is such that all openings face the lower end of the coolant buffer tank and that the coolant from the coolant buffer tank is on the peripheral surface of the other hollow profile body. Arranged in the lower region of the heated liquid buffer tank to be fed back into the cooling means via another hollow profile body having an opening in a portion, In the upper area of the coolant buffer tank so that all openings face towards the upper edge of the coolant buffer tank It is location.

  In this way, the coolant from the cooling means having a relatively low temperature level is guided to the lower end of the coolant buffer tank by the hollow profile body arranged in the lower region of the coolant buffer tank. The cooling buffer tank may be operated as a stratified storage tank in a very efficient manner because it can be pushed or pushed. Upon charging, this coolant having a low temperature level moves a layer of coolant having a moderate temperature level toward a region above the coolant buffer tank. On the other hand, a stratified or stratified coolant with a relatively high temperature level in the upper region of the coolant buffer tank can be transported to the cooling means of the heat pump via another hollow profile body It is. In this way, undesired mixing of the coolant layers with different temperature levels in the coolant buffer tank and thus unnecessary temperature leveling can be prevented. In the following, this is because a stable temperature level of the coolant in the lower region and the upper region of the coolant buffer tank can be provided over time when charging the coolant buffer tank, Allows operation of the heat pump at the highest possible COP for cooling.

  Furthermore, based on the cooling requirements for the first and second pasteurization lines and based on the temperature of the coolant in the coolant buffer tank, the coolant from the lower region of the coolant buffer tank is Via the first cooling heat exchanger and / or into the second cooling heat exchanger and cooling from the first cooling heat exchanger and / or the second cooling heat exchanger It may be advantageous for the liquid to be returned into the upper region of the coolant buffer tank via another hollow profile body.

  In this way, the coolant buffer tank can be further efficiently operated as a layered buffer tank during removal. Using such a layered liquid buffer tank, a stable long-time operation of the heat pump at a high COP is enabled.

  Independently, according to another embodiment of the present invention, a treatment liquid having a low temperature level of the first and / or second pasteurization line, based on the cooling requirements for the first and second pasteurization lines, It may include further cooling by at least one additional cooling device.

  With this strategy, the need for exceptionally low temperature levels for processing liquids in either the final cooling demand peak or pasteurization line can be addressed by at least one additional cooling device And a heat pump with appropriate cooling capacity may be used.

  In each case, it may be advantageous for the treatment liquid or liquids having a low temperature level to be further cooled by passing the treatment liquid through the heat exchanger of at least one air-cooled cooling tower. .

  Together with this, the treatment liquid or liquids can be further cooled by an additional cooling device having a high cooling capacity. Contamination / contamination of one or more other processing liquids during cooling, such as processing liquid contamination / contamination potentially caused by direct contact with cooling air by the heat exchanger, It can be prevented efficiently.

  In addition, enhanced pasteurization equipment is also provided to achieve the objectives of the present invention.

  The pasteurization facility includes a first pasteurization line and at least a second pasteurization line. Each of the first and second pasteurization lines includes at least one heating zone and at least one cooling zone, and each of the heating zone and the cooling zone receives a temperature-conditioned treatment liquid in its respective one. A liquid supply means configured to meter into the area is provided. Each of the first and second pasteurization lines is configured to convey a sealed container filled with foodstuff through at least one respective heating zone and subsequently through at least one respective cooling zone. Transporting means. The pasteurization facility further includes a heat pump having a heating unit for heating the heating liquid and a cooling unit for cooling the cooling liquid.

  The heating means of the heat pump includes at least the first heating heat exchanger via the liquid transport line and at least one shut-off means disposed only between the heating means and the first heating heat exchanger. And the heating means is further at least one further separate disposed only between the liquid transport line and between the heating means and the second heating heat exchanger. And is operatively connected to the primary side of the second heating heat exchanger via the blocking means. At least one heating liquid transfer means circulates the heating liquid through the heating means and through the primary side of the first heating heat exchanger and / or through the primary side of the second heating heat exchanger. Is arranged for. The secondary side of the first heating heat exchanger is connected to the injection line and the discharge line for the treatment liquid of the first pasteurization line, and the secondary side of the second heating heat exchanger Is connected to an injection line and a discharge line for the treatment liquid of the second pasteurization line. In addition to this, the cooling means of the heat pump has the first cooling via the liquid transport line and at least one shut-off means arranged only between the cooling means and the first cooling heat exchanger. It is operatively connected to the primary side of the heat exchanger, and the cooling means is further at least one arranged only between the liquid transport line and the cooling means and the second cooling heat exchanger. Operatively connected to the primary side of the second cooling heat exchanger via two shut-off means.

Is arranged for. The secondary side of the first cooling heat exchanger is connected to the injection line and the discharge line for the treatment liquid of the first pasteurization line, and the secondary side of the second cooling heat exchanger Is connected to an injection line and a discharge line for the treatment liquid of the second pasteurization line.

  This structural design of the pasteurization facility allows the heating liquid to be heated by the heating means of the heat pump during operation of the pasteurization facility. Furthermore, the heated heating liquid can then be used by the first heating heat exchanger to heat the processing liquid having a high temperature level of the first pasteurization line, And / or the heated heating liquid from the heating means of the heat pump has a high temperature level of the second pasteurization line by the second heating heat exchanger based on the practical heating requirements of the pasteurization line. It can be used to heat the treatment liquid. In addition to this, the coolant can be cooled in the cooling means of the heat pump during operation of the pasteurization facility, and then the first pasteurization line by the first cooling heat exchanger. Can be used to cool process liquids having a low temperature level and / or based on the actual cooling requirements of the pasteurization line, the second cooling heat exchanger can It can be used to cool processing liquids having low temperature levels in the pasteurization line.

  This realizes improved energy efficiency during operation of the pasteurization facility because the heating capacity and cooling capacity of the heat pump can be utilized to a very high degree. This allows heat pump operation in the region of very high COPs for heating and cooling. In order to measure the actual heating and cooling requirements of the pasteurization line during operation, a temperature sensor can be placed at an appropriate location within the pasteurization line. One skilled in the art will understand that a pasteurization facility may of course include more than two pasteurization lines. For example, in the same form as the first and second pasteurization lines, the third pasteurization line, the fourth pasteurization line, etc. are heat pumped by the third and fourth heating and cooling heat exchangers. It may be connected to.

  In one embodiment of the pasteurization facility, the outlet of the heating means passes through the liquid transport line and at least one blocking means arranged only between the outlet of the heating means and the upper region of the heated liquid buffer tank. Connected to the upper region of the heating liquid buffer tank, and the inlet of the heating means is disposed at least between the liquid transfer line and the inlet of the heating means and the lower region of the heating liquid buffer tank. Connected to the lower region of the heating liquid buffer tank via one blocking means, and separately at the other position of the heating liquid buffer tank, the upper region and the lower region of the heating liquid buffer tank, Via the liquid transport line and at least one other shut-off means arranged only between the heating liquid buffer tank and the first heating heat exchanger, Operatively connected to the primary side of one heating heat exchanger, and the upper region and lower region of the heating liquid buffer tank are the liquid transfer line, the heating liquid buffer tank, and the second heating heat exchange.

And / or from the first heating heat exchanger and / or from the second heating heat exchanger, the heating liquid is arranged to return into the lower region of the heating liquid buffer tank.

  During the operation of the pasteurization facility and according to the actual heating requirements regarding the pasteurization line, the heated heating liquid from the heating means of the heat pump can be sent into the upper area of the heating liquid buffer tank And the heating liquid can be returned from the lower region of the heating liquid buffer tank into the heating means of the heat pump. Thus, the excess heat energy generated in the heating means of the heat pump in this way can be temporarily stored in the heated liquid buffer tank for subsequent use, so that the heating requirement in the pasteurization line is reduced. The heated liquid buffer tank is particularly useful when it is low or absent. The heated liquid buffer tank may preferably be configured as a layered storage tank with temperature sensors located at various heights within the heated liquid buffer tank. In this case, based on the heating requirements for the first and second pasteurization lines during operation of the pasteurization facility, the heating liquid is sent from the upper region of the heating liquid buffer tank to the first heating heat exchanger and / or the second heating paste. The heating fluid from the first heat exchanger and / or from the second heat exchanger during operation is stored in the heating fluid buffer tank. It can be returned into the lower region. By using the heating liquid buffer tank in this way, the heating capacity of the heat pump can be utilized to a higher degree, and additional heating means with lower energy efficiency compared to this heat pump Can be limited at least during operation of the pasteurization facility.

It will include that they are located within.

  With these structural elements, the heated liquid buffer tank can be operated as a layered buffer tank during operation of the pasteurization facility. At the time of charging, the heated heating liquid from the heating means can be fed into the heating liquid buffer tank via the hollow profile body arranged in the upper region. This hollow profile body can be arranged, for example, approximately in the middle of the upper third of the heated liquid buffer tank. Thereby, the hollow profile main body functions as a guiding means, and the heating liquid having a high temperature level from the heating means of the heat pump is pushed toward the upper end of the heating liquid buffer tank at the time of feeding. This causes the heating liquid layer having a medium temperature level to move toward the lower region of the heating liquid buffer tank. Heating liquid having a relatively low temperature level from the lower area of the heating liquid buffer tank is routed via another hollow profile body located in the lower area of the heating liquid buffer tank during operation of the pasteurization facility. Can be returned into the heating means. This another hollow profile body can be arranged, for example, approximately in the middle of the lower third of the heated liquid buffer tank. Through this hollow profile body, unwanted mixing of heated liquid layers having different temperature levels in the heated liquid buffer tank can be prevented during operation of the pasteurization facility. In the following, this means that a stable temperature level of the heating liquid in the upper and lower areas of the heating liquid buffer tank is provided for a long time when charging the heating liquid buffer tank with thermal energy. Allows the operation of the heat pump at the highest possible COP for heating.

  Furthermore, a liquid transfer line extending from the upper region of the heating liquid buffer tank to the first heating heat exchanger and a liquid transfer line extending from the upper region of the heating liquid buffer tank to the second heating heat exchanger include the heating liquid buffer. Connected to the hollow profile body located in the upper region of the tank, the liquid transport line extending from the first heating heat exchanger, and from the second heating heat exchanger to the lower region of the heating liquid buffer tank It may be advantageous for the leading liquid transport line to be connected to a hollow profile body which is arranged in the lower region of the heated liquid buffer tank.

  From the upper region of the heating liquid buffer tank during the operation of the pasteurization facility, in response to the heating requirements for the first and second pasteurization lines, and based on the temperature of the heating liquid in the heating liquid buffer tank Of the heating liquid can be fed into the first heating heat exchanger and / or the second heating heat exchanger via the hollow profile body, and the first heating heat exchanger and The heating fluid from the second heating heat exchanger can be returned to the lower region of the heating fluid buffer via another hollow profile body. This further allows for efficient operation of the heated liquid buffer tank as a layered buffer tank during removal.

  Independently, one embodiment of this pasteurization facility is characterized in that the outlet of the cooling means is at least one shut-off arranged only between the liquid transport line and the outlet of the cooling means and the lower region of the coolant buffer tank. Connected to the lower area of the coolant buffer tank via the means, and the inlet of the cooling means is only between the liquid transfer line and the inlet of the cooling means and the upper area of the coolant buffer tank. Connected to the upper region of the coolant buffer tank via at least one shut-off means arranged in the lower region of the coolant buffer tank separately at other positions of the coolant buffer tank And at least one additional shut-off means, the upper region being arranged only between the liquid transport line and the coolant buffer tank and the first cooling heat exchanger And is operatively connected to the primary side of the first cooling heat exchanger, and a lower region and an upper region of the cooling buffer tank are connected to the liquid transfer line, the cooling liquid buffer tank, and the second Operatively connected to the primary side of the second cooling heat exchanger via at least one other shut-off means arranged only between the cooling heat exchanger and at least One separate coolant transfer means is connected to the coolant from the lower region of the coolant buffer tank through the primary side of the first cooling heat exchanger and / or through the primary side of the second cooling heat exchanger. And is arranged to return the coolant into the upper region of the coolant buffer tank.

  Based on or in response to actual cooling requirements for the pasteurization line during operation of the pasteurization facility, the cooled coolant from the heat pump cooling means is pumped into the lower region of the coolant buffer tank. And the coolant can be returned from the upper region of the coolant buffer tank into the cooling means of the heat pump. Thus, the coolant buffer tank may serve as a temporary storage device for cooled coolant having a low temperature level during operation, and the cooling capacity of the heat pump is low or absent. Can be fully used even if the cooling requirement is present in any of the pasteurization lines. The coolant buffer tank may preferably be configured as a stratified storage tank with temperature sensors located at various heights within the heated liquid buffer tank. In this case, in order to cool the processing liquid having a low temperature level in the first pasteurization line and / or the second pasteurization line, in response to a cooling request relating to the operating first and second pasteurization lines. In addition, the coolant can be fed into the first cooling heat exchanger and / or the second cooling heat exchanger from the lower region of the coolant buffer tank, and the first cooling heat exchanger And / or the coolant from the second cooling heat exchanger can be returned into the upper region of the coolant buffer tank. By using the coolant buffer tank in this manner, the cooling capacity of the heat pump can be utilized to a higher degree, and the use of additional cooling means with lower energy efficiency compared to the heat pump Can be prevented at least during operation of the pasteurization facility.

  In another embodiment of the pasteurization facility, a liquid transport line from the outlet of the cooling means to the lower region of the coolant buffer tank is connected to the hollow profile body having an opening in a portion of the peripheral surface of the hollow profile body. And the hollow profile body is disposed in the lower region of the coolant buffer tank such that all openings face toward the lower end of the coolant buffer tank, the coolant buffer A liquid conveying line from the upper region of the tank to the inlet of the cooling means is connected to another hollow profile body having an opening in a portion of the peripheral surface of the other hollow profile body, and this other hollow The profile body has a coolant buffer so that all openings face towards the upper edge of the coolant buffer tank. It will include that it is arranged above the region of the tank.

  By using these structural elements, the coolant buffer tank can also be operated as a layered buffer tank during operation of the pasteurization facility. Upon charging, the cooled coolant from the heat pump cooling means can be fed into the coolant buffer tank via the hollow profile body located in the lower region. This hollow profile body can be arranged, for example, approximately in the middle of the lower third of the coolant buffer tank. Thereby, the hollow profile body functions as a guiding means, and the cooling liquid having a low temperature level from the cooling means is pushed toward the lower end of the cooling liquid buffer tank when being fed. This moves the coolant layer having a medium temperature level toward the upper region of the coolant buffer tank. A coolant having a relatively high temperature level from the upper region of the coolant buffer tank is routed through another hollow profile body located in the upper region of the coolant buffer tank during operation of the pasteurization facility. Can be returned into the cooling means. This other hollow profile body can be arranged, for example, approximately in the middle of the upper third of the coolant buffer tank. Through these hollow profile bodies, unwanted mixing of coolant layers having different temperature levels in the coolant buffer tank can be prevented during operation of the pasteurization facility. In the following, this is because a stable temperature level of the coolant in the lower region and the upper region of the coolant buffer tank can be provided over time when charging the coolant buffer tank, Allows operation of the heat pump at the highest possible COP for cooling.

  Furthermore, a liquid transfer line extending from the lower region of the coolant buffer tank to the first cooling heat exchanger and a liquid transfer line extending from the lower region of the coolant buffer tank to the second cooling exchanger are provided as the coolant buffer tank. Connected to the hollow profile body located in the lower region of the liquid, a liquid transport line extending from the first cooling heat exchanger, and a liquid from the second cooling exchanger to the upper region of the coolant buffer tank It may be convenient for the transport line to be connected to a hollow profile body located in the upper region of the coolant buffer tank.

  Based on the cooling requirements of the first and second pasteurization lines and based on the temperature of the coolant in the coolant buffer tank, coolant from the lower region of the coolant buffer tank passes through the hollow profile body. And can be fed into the first cooling heat exchanger and / or the second cooling heat exchanger, and the first cooling heat exchanger and / or the second cooling heat exchanger. Can be returned to the upper region of the coolant buffer tank via another hollow profile body.

In this exemplary embodiment shown in FIG. 1, the first and second pasteurization lines 2, 3 are configured as so-called tunnel pasteurizers. Each of the pasteurization lines 2, 3 comprises transport means 5, such as a conveyor belt or other transport device, configured to transport the containers. In the conveying direction of the container 4, each of the first and second pasteurization lines 2, 3 has heating zones 7, 8 for continuously heating the container and the foodstuff, and further heats the foodstuff to a low temperature. There will be separate heating zones 9, 10 for sterilization and cooling zones 11, 12 for continuously cooling the container 4 and the foodstuff. In this case, during the operation of each of the first and second pasteurizations 2, 3, the sealed container 4 filled with foodstuffs, for example beverages, is connected to the heating and pasteurization zones 7, 8, 9, 10. It can be passed and then transferred through the cooling zones 11, 12.

  The first and second pasteurization lines 2, 3 shown schematically in FIG. 1 comprise the same elements. Of course, depending on the requirements or objectives, the pasteurization line can comprise more or fewer areas compared to the exemplary embodiment shown, for example, in FIG. . Thereby, the pasteurization line 2, 3 comprises at least one heating zone 7, 8, 9, 10 and at least one cooling zone 11, 12 through which the containers are transferred. . Similarly, further processing areas can be provided. For example, an area for drying the outside of the container 4 can be provided subsequently for a cooling area 12 arranged at the end in the conveying direction 6. For the sake of clarity, this alternative design of pasteurization line is not described. Those skilled in the art will appreciate that the present invention can be implemented using such alternative designs of pasteurization lines.

  During operation, the food product is first and second low temperature by metering a temperature conditioned treatment liquid onto the respective container 4 in each of the heating zones 7, 8, 9, 10 respectively. It is possible for the sterilization lines 2, 3 to be heated independently of one another in respective heating zones 7, 8, 9, 10. The food product is then fed into the first and second pasteurization lines 2, 2, by metering a temperature-adjusted treatment liquid onto the respective container 4 in each of the cooling zones 11, 12. 3 in each respective cooling zone 11, 12 can be cooled independently of each other.

A portion of the processing liquid from the bottom section 15 may be transferred to other temperature processing sections 7, 8, 9, 10, 11, 12 via the recovery line 16. In each pasteurization line 2, 3, a portion of the processing liquid from the bottom section of the last cooling section 12 may be transferred to, for example, the first heating section 7, and vice versa. Such recovery of the treatment liquid is particularly significant because the temperature of the treatment liquid decreases when the container 4 is heated in the heating zone 7 and the temperature of the treatment liquid rises when the vessel 4 is cooled in the cooling area 12. is there. Accordingly, direct reuse of the processing liquid for heating and cooling of the container 4 is advantageous, at least with respect to the exemplary pasteurization lines 2 and 3 shown in FIG.

In order to cool the foodstuff in the container in a regulated manner, a processing liquid having a temperature level of about 50 ° C. may be fed into the cooling zone 11 and a processing liquid having a temperature of about 30 ° C. May be fed into the respective cooling zone 12 of the pasteurization line 2, 3. However, the required temperature level for each individual temperature treatment zone 7, 8, 9, 10, 11, 12 may vary widely, for example depending on the food product to be pasteurized. Certain food products may require specific high pasteurization temperatures, while food products containing temperature sensitive components require cooling to specific low temperature levels, for example after pasteurization It may be.

  By using the treatment liquid recovery and by using the metering device 19, the temperature of the individual treatment liquid streams is changed to the respective individual temperature treatment zone 7, 8, 9, 10, 11, 12 and can be set and / or adjusted. However, due to the mixing of the processing liquid flow, the internal transfer of thermal energy and the exchange of thermal energy with the environment, a partial amount of processing liquid in the first and second pasteurization lines 2 and 3 and / or Alternatively, heating and cooling means are still required to bring the flow to a temperature level that is adapted for effective heating and cooling of the foodstuffs in each container 4.
