Definitions

  • the invention relates to apparatus and methods for storing substantially liquid substances, ie substances containing at least one liquid, e.g. in the form of foods, or beverages or liquid-containing foods to be stored in a state of very low viscosity.
  • substances which essentially have the behavior of a liquid are frequently to be stored in corresponding containers, wherein mixing of the substance is frequently to be achieved or preserved and at the same time the substance is to be brought to or maintained at a desired temperature, which often deviates from the ambient temperature.
  • viscous substances ie, as substances whose predominant component is a liquid
  • solid substances such as in the form of suspended particles, larger solid food fractions and The same may be admixed and in which also in addition to or as an alternative to solid suspended particles and gases may be added.
  • viscous substances are found in the food industry and the food industry in the form of beverages, soups, and the like.
  • the corresponding viscous substance must be dispensed in a metered manner, for which corresponding output devices or "dispensers" are available.
  • beverage dispensers or dispensers are used in which the viscous substance, for example in the form of a beverage, is kept at or brought to a desired temperature level in order to be able to remove corresponding metered quantities in a controlled manner.
  • containers are often used which are brought into thermal contact with a cooling device, so that over the container wall, which is often provided as a thermally highly conductive material at least in the contact area with the heat sink, an efficient temperature exchange can take place.
  • a mechanical stirring device is usually provided in the container. Since stringent hygienic requirements must be met, especially in the field of food technology, a mechanical decoupling of the agitator from the actual Drive device often accomplished that, for example, magnetically coupled stirrers are provided in the beverage container.
  • the separation of the actual drive region from the mechanical agitator achieves an improvement in terms of hygiene and there is also a higher degree of flexibility in the use of suitable drive systems, but nevertheless the mechanical agitator is in direct contact with the viscous substance, ie the beverage liquid and The like, so that depending on the composition of the viscous substance appropriate cleaning operations are necessary, which in turn, however, in addition to the corresponding high effort, the risk that by the cleaning process itself a contamination of the container interior and thus also to be stored in the viscous substance.
  • the viscous substance ie the beverage liquid and The like
  • a device for controlling the temperature of a viscous substance which has an outer container for receiving a heat transfer fluid. Furthermore, the device comprises an inner container for receiving the viscous substance to be tempered, wherein the inner container is arranged in the outer container and has at least one reversibly deformable container wall region which separates the viscous substance from the heat transfer liquid. Furthermore, the device comprises a heating and / or cooling device, which can be thermally coupled to the heat exchange fluid during operation for heat exchange. Furthermore, the device comprises a circulation device, which is designed to generate a movement or flow in the heat transfer fluid and / or the viscous substance to be tempered.
  • the invention is based on the idea of storing a viscous substance, that is to say a very easily deformable substance, in a suitable container which has at least one resiliently deformable wall region and thus enables a mechanical action through this wall region on the viscous substance. At least this wall region also serves for thermal coupling of the heat transfer fluid to the viscous substance, so that in a mechanical movement, in particular a flow, in one of the two liquid-like Substances (heat transfer fluid and viscous substance) also causes a corresponding movement or flow in the other substance.
  • the term "tempering” is to be understood as meaning that the viscous substance for heat exchange with the heat transfer fluid should be kept at a desired temperature or within a predetermined range or brought to this temperature, of which conceptually also Cooling or heating of the viscous substance is detected.
  • the tempering thus takes place by a thermal coupling of the viscous substance over at least the reversibly (yielding) deformable region, wherein preferably a correspondingly small wall thickness is used, so that even with relatively low thermal conductivity of the deformable material takes place an efficient coupling to the heat transfer fluid.
  • a reversibly deformable material As a reversibly deformable material is to be understood that when exposed to an external force to a deflection of at least one millimeter and preferably several millimeters to several centimeters in a position, so that a mechanical movement of the fluid for heat transfer in the form of a successful flow upon impact on the reversibly deformable partition a corresponding displacement of the viscous substance with the partition wall is possible without irreversible damage to the deformable material occurs.
  • an elastic material in the form of a membrane may be considered as a reversibly deformable material, as long as it is provided in a state and composition of material allowing for a corresponding mechanical deflection.
  • substantially non-elastic materials which are not dimensionally stable can also be considered as reversibly deformable materials.
  • a bag as set forth in claim 9 is to be understood as a container having wall portions which are reversibly deformable, wherein the base material of the bag may be elastic or inelastic.
  • the viscous substance is a foodstuff, a beverage or another liquid-based foodstuff, wherein the device according to the invention can be used for efficient mixing and tempering, as also stated above.
  • the advantages of a missing mechanism within the inner container for circulating the viscous substance can be particularly advantageous, since high hygienic requirements must be met in this sector.
  • the substance is only in contact with the inner walls of the inner container.
  • the inner container has an output device in order to dispense the viscous substance in a metered manner.
  • the device can be used as a dispenser for liquid based foods or the like, with particular emphasis on the benefits of good mixing of the substance and its good thermal coupling to the heat transfer fluid.

  • corresponding heating and / or cooling surfaces can be produced by large surfaces within the container in the form of loops laid in loops, by corresponding cooling or heating vanes, and also suitably designed surface areas of the container itself can serve as efficient heat transfer surfaces.
  • the heat transfer surface is designed so that it does not obstruct the flow within the heat transfer fluid unnecessarily, so that on the one hand an efficient mixing of the heat transfer fluid itself takes place and also the flow generated by the circulation and thus the mechanical interaction with moldable wall areas is not unnecessarily reduced.
  • the circulation device is arranged within the outer container.
  • the circulation device can be provided in the form of known components, for example by a pump wheel which is driven by a drive unit driven outside the container, while in other embodiments also the complete drive unit within the outer container may be provided, provided that the drive is sealed and is also designed for the temperatures, with which the circulated heat transfer fluid is applied.
  • the circulation device is designed such that a circulation of the heat transfer fluid is generated around at least a part of the inner container, since in this case it has been found within the scope of the invention that surprisingly a very efficient thermal coupling results and also the degree of mixing in the viscous substance is sufficiently high, so that even emulsion-like substances or liquids with larger proportions of solids remain well mixed.
  • a suitable circulation is accomplished inter alia also by the fact that the dimensions of the inner and the outer container are coordinated so that a sufficiently large gap is always available, so that a relatively unobstructed flow can build up under the action of the circulating device.
  • the heating and / or cooling device has at least one heat transfer surface, which is mounted outside the outer container.
  • the inner structure of the outer container with a high degree of flexibility can be given and about the desired dimensions of the inner container or the degree of deformation during the discharge of the viscous substance, if the inner container in the form of an output device for Liquid-like substances used to be adjusted, so that due to the improved flow conditions, the thermal and mechanical coupling to the viscous substance can be improved.
  • a simpler internal structure which may also be advantageous when loading the outer container, ie. during insertion of the inner container, and the like.
  • a suitable circulating means may be provided outside the container, for example in the form of a pump and the like, wherein at the same time the application of heat or cold can take place, due to the modularity of the container system on the one hand and the drive and heating / cooling components on the other hand, a high Degree of flexibility is ensured for the configuration of the system. For example, different containers with the same circulation and heating / cooling system can be operated simultaneously if necessary.
  • the heating and / or cooling device is designed to keep the heat transfer fluid at a temperature in a range of -20 ° C to 100 ° C. Cooling temperatures below 15 ° C or below 10 ° C and above 1 ° C are preferred.
  • This design results in many types of applications for the device according to the invention, especially in the field of food.
  • the heat transfer fluid it is possible in this temperature range of the heat transfer fluid to cool almost all beverage-like substances or to stockpile and also to dispense in a hot state, so that immediate consumption at a desired temperature is possible.
  • many types of heat transfer fluids may be used, such as water, with appropriate antifreeze added, so that, in principle, a single agent and corresponding additives can cover the entire temperature range.
  • the heating and / or cooling device can also be designed accordingly, so that they can be operated only in a predetermined sub-interval, for example in the form of cooling, when generally cooled liquid-like substances are to be stored.
  • the device further comprises a reservoir, which can be coupled to the outer container with a fluid connection for temporarily receiving the heat transfer fluid.
  • a reservoir which can be coupled to the outer container with a fluid connection for temporarily receiving the heat transfer fluid.
  • the aforementioned object is achieved by a method for controlling the temperature of a viscous substance.
  • the tempering of the viscous substance is effected by indirect thermal and mechanical coupling of a heat transfer fluid to the viscous substance via a suitable deformable partition wall or membrane, e.g. in the form of a bag, so that there is always an area at least even with changing volume of the viscous substance, which serves to separate the heat transfer fluid and the viscous substance and yet makes the indirect contact for thermal and mechanical coupling.
  • the generation of a movement, in particular flow leads on the one hand to an efficient temperature compensation within the heat transfer fluid, which is coupled to a heat reservoir, and on the other hand to a corresponding efficient temperature distribution in the viscous substance, at the same time given by the mechanical coupling and a good mixing.
