Definitions

• the invention relates to an apparatus and a method for pasteurizing liquid-filled containers, such as beverage bottles or beverage cans.
• part of the heat exchange is realized by providing a heat pump between one or more segments of the pasteurization zone and those of the cooling zone.
• Pasteurization plants and processes for the preservation of food in the beverage industry are known and in many uses.
• containers such as bottles, cans, bags or the like are passed substantially continuously through a pasteurizer.
• pasteurization devices and methods are constructed in such a way that, for gentle heating and cooling, the liquid-filled containers are conveyed through segments which are tempered at respectively low temperatures. Disposed between the segmented heating and cooling zone is the pasteurization zone, which may also be segmented, and in which the temperature is maintained at a substantially high level.
• DE 43 14 662 A1, DE 203 17 441 U1, DE 100 42 528 A1, DE199 08 035 A1 or EP 0 430 907 B1 describe such pasteurization apparatuses and methods. Inside the device, the containers are sprayed or showered with liquid to realize the heating, cooling or the isothermal state.
• the pasteurization process or the sanitation is essentially dependent on the temperature and the residence time. Since the temperature of the closed containers can only be increased to a limited extent, the residence time must be extended so that the pasteurization devices are structurally very large. They contain in normal operation a large volume of liquid with a high energy content. It is also known to pass the liquid of the segments of the heating and cooling zone back and forth in a suitable manner in order to realize the greatest possible heat recovery.
• the object of the invention is therefore to provide a structurally improved pasteurization device which has no economic and energetic disadvantages compared to the known prior art.
• This object is achieved by means of the present invention.
• This relates to a pasteurization apparatus for the thermal treatment of liquids present in sealed containers, comprising a heating zone, a pasteurization zone and a cooling zone, each zone being able to consist of one or more segments.
• the filled liquid containers are conveyed through all segments from the inlet of the pasteurization device to their outlet, sprinklers being provided for heating, pasteurization and / or cooling in the segments.
• the irrigation liquid of one or more segments is collected in collecting containers and these liquids are exchanged between individual segments for the purpose of heating or cooling in a suitable manner.
• the pasteurization device in this case comprises a heat pump, which is connected to a segment of the pasteurization zone and a segment of the cooling zone via lines and delivery units such that a part of the heat energy of the liquid volume of a segment of the cooling zone, by means of this heat pump in a segment of the pasteurization zone can be transferred.
• An embodiment of the pasteurization is that with the
• Receiving container of a Abkühlsegmentes another delivery unit and a line are connected, said conduit leading to the cold side of the heat pump, with which it is in thermal contact, and this line leads from there downstream of the sprinkler of a Abkühlsegmentes.
• This direct heating of a portion of the trickling water represents a very effective heat input into the pasteurization segment because no heat exchanger is used downstream. Furthermore, the regulation of the target temperature on the mixture with an appropriate amount of hot water is easy to implement.
• An improvement consists in providing a mixing device or mixing section upstream of the sprinkling device into which, in addition to the line coming from the heat pump, there is also a fresh water line.
• the segment of the cooling zone connected via the heat pump and suitable lines is a segment which is not recuperatively connected to a segment of the pasteurization zone.
• the variant in which the segment of the cooling zone connected via the heat pump is a segment which is recuperatively connected to a segment of the pasteurization zone.
• combinations are conceivable or process management possible, taking into account temporary climatic conditions.
• Such an embodiment could also be that more than one segment of the cooling zone via a heat pump and suitable lines are connected to one or more segments of the pasteurization zone, which segments of the cooling zone can represent recombatively linked segments or cooling segments without a recuperative linkage.
• the invention also encompasses a process for the pasteurization of liquid media, in which a pasteurization apparatus according to one of the aforementioned embodiments is used.
• An optimized variant consists in that the liquid which comes from the heat exchanger and flows to a pasteurization segment has at most the desired temperature of the irrigation liquid of the respective segment and ideally has a temperature which is 5 ° to 15 ° below this SoII temperature.
• Such a variant of the method has the advantage that the heat pump can run continuously with always the same power and only a comparatively small volume flow of hot water has to be added. This volume flow is taken as a circulation liquid the pasteurization segment and heated in a known manner by means of external heat exchanger.
• a pasteurization device of known design with the inlet temperature of 12 ° C and an outlet temperature of 31, 8 0 C formerly 15m in length could be built shortened by the use of a heat pump by almost 3m.
• the pasteurization device in the design according to the invention exhibited an even lower starting temperature of 30.9 C at an identical inlet temperature. This could be achieved without an increase in the operating costs for the energy requirement.
• FIG. 1 shows the pasteurization device 1, which has an input 2, an output 3 and a plurality of segments 4-11. From left to right thus conveyed into the entrance 2 and schematically represented vessels through the heating segment 4, heating segment 5, Pasteurticiansseg- elements 6, 7 and 8, cooling segment 9, cooling segment 10 and cooling segment 11.
• the segments 4 and 10 and the segments 5 and 9 are recuperatively interconnected, in which the collected irrigation water collected, funded by means of pumps 12 and via the lines 13 to the other segment and there trickled over suitable and known Sprinklers 14.
• the irrigation water in the pasteurization segments 7 and 8 is also collected and re-trickled as internal circuit in the same segment via the sprinklers 15.
• a partial flow 16 is continuously withdrawn and heated by a heat exchanger. shear 17, and then trickled into the pasteurization segments 7 and 8.
• the heat pump 18 with a cold side 19 and a warm side 20 can be seen.
• the cooling segment 11 and the pasteurization segment 6 are thermally indirectly connected via the heat pump 18.
• the collected in the cooling segment 11 water is removed and promoted to the cold side 19 of the heat pump 18, where it is deprived of energy, so that colder water flows back into the cooling segment 11 and is trickled there directly.
• the energy fraction thus obtained and transferable is released on the hot side 20 of the heat pump 18 to the irrigation water which has been removed via the line 21 and pump 22 from the collecting container 23 of the pasteurization segment 6.
• the hot return water coming from the heat pump 18 is mixed with the partial flow of hot water from line 25 and / or a partial stream of cold water from line 26 in a suitable manner.
