Definitions

  • the present invention relates to a cooling plate arrangement according to the features of the preamble of claim 1 and a method for tempering, in particular freezing and/or thawing, of material present in containers, in particular a liquid.
  • the US4898294 discloses frozen food containers for delivery on an aircraft.
  • the U.S. 2003/0080126 A1 discloses a system for controlled freezing and thawing of biopharmaceutical material. Permanently installed cooling plates are always used.
  • the WO 2005/075907 A1 discloses merchandise display furniture with refrigerated display shelves.
  • the US4203486 B discloses a system with separate devices for cooling and heating food.
  • the US 1896953A discloses a cold plate assembly according to the preamble of claim 1
  • bottles with a capacity of up to 10 liters or so-called single-use bags with a capacity of up to 16 liters are frozen. It is also known to use stainless steel tanks in which the manufactured product is frozen.
  • Single-use bags are essentially flexible bags, preferably made of plastic, which are not only liquid-tight if possible, but also protect against contamination, for example, as well as possible.
  • the present invention has therefore set itself the task of providing methods and/or devices that can be used to simplify the freezing and/or transport of materials, in particular liquids or intermediate products or end products of the biopharmaceutical production process.
  • the cooling plate arrangement is achieved by the features of claim 1. Because the surface area of the at least one cooling plate protrudes freely away from the carrier, so that the at least one cooling plate can be inserted into a hollow body and removed from the hollow body by moving the carrier via an opening, the disposable containers no longer have to be placed in a corresponding device or be spent, but the at least one cooling plate can be introduced into that hollow body in which the container for the material (for example with the disposable containers mentioned) are already arranged.
  • the cooling plates are movably mounted essentially perpendicular to the surface area of the cooling plates in order to establish contact between the cooling plates and the containers after the cooling plates have been introduced into the hollow body.
  • a movement device can be provided for moving the cooling plates. Similar to the cooling plates, this can be mounted on the carrier and can be inserted into the body. This makes it particularly easy to provide the lifting function - or general movement function - in the body without each body having to have a separate movement device.
  • the invention can always be used if handling of the goods to be frozen is not desired (because, for example, as in the biopharmaceutical production process, the sterility or integrity of the material or the bag could be introduced).
  • a body for containers to be temperature-controlled can be provided as a complement to the cooling plate arrangement according to the invention, with holding devices being provided in the hollow body for holding the containers spaced apart in the hollow body, which are arranged in such a way that at least one cooling plate can be inserted and removed via the opening between the containers .
  • the at least one cooling plate can be introduced into a hollow body and removed from the hollow body by moving the carrier via an opening.
  • the cooling plate arrangement can have at least two cooling plates, but that as a rule more cooling plates are used. Two cooling plates ensure that a container to be cooled is cooled on both sides. Of course, designs with only a single cooling plate are also conceivable in principle. It is also possible that only a single container per freezing process is cooled with the cooling plate arrangement. As a rule, of course, there will be more.
  • the at least one cooling plate is referred to with the term "cooling plates" in the plural, the meaning always including "at least one cooling plate”.
  • the containers can contain the material to be frozen directly, or provision can be made for the single-use bags, bottles or tanks mentioned to be arranged in the containers.
  • the containers can be particular as in the international Application WO2018129576 be formed, reference is made to the disclosure of which in relation to the design of the container and the objects arranged therein (e.g. lining foam, arrangement of the single-use bag).
  • the cooling plates do not have to be perfectly flat. In certain situations it can be advantageous to use curved or differently shaped plates.
  • plates are understood to mean bodies whose surface area is many times greater than the thickness. In principle, the ratio of a characteristic Measure of the surface area and the plate thickness greater than 2, preferably greater than 10 and particularly preferably greater than 20.
  • a core aspect of the invention is that the cooling plates of the cooling plate arrangement are mounted so that they cantilever that they can be introduced into the space in which the containers to be cooled are already present. It should be mentioned that the invention can be used not only for freezing the material in the containers, but also for - preferably temperature-controlled - thawing of frozen material in the containers.
  • Protection is also sought for a method for tempering, in particular freezing and/or thawing, of material present in the containers, in particular a liquid, according to the features of claim 16.
  • the cooling plates can have an essentially rectangular base area, which represents a particularly simple embodiment of the invention.
  • the cooling plates can only be mounted at the edges.
  • the cooling plates can only be mounted on one side at the edge.
  • a rotating support device e.g. in the form of a frame projecting away from the carrier
  • the mounting of the cooling plates for example in the form of a frame, must be designed in such a way that the at least one cooling plate can be brought in and taken out according to the invention, for example by making the frame thin enough.
  • cooling plates mounted on the carrier can be provided, which overlap and are free from one another. “Overlap” can be understood to mean that the cooling plates overlap in a view along an axis perpendicular to the planes of the cooling plates.
  • the overlapping cooling plates can be arranged essentially one above the other.
  • the movement device can be designed as a scissor lift.
  • the cooling plates can have temperature control channels for a temperature control medium and a device can be provided by means of which the temperature control medium is temperature controlled and pumped through the temperature control channels.
  • temperature control can mean both cooling and heating as well as regulated or controlled running of a temperature profile. In the context of the temperature profile of course freezing, thawing or repeated switching between the two phase states can be provided.
  • the holders for the containers can be designed as projections in the hollow body to support the containers. This applies in particular when the containers are arranged essentially one above the other.
  • the containers then simply rest on the projections and are particularly easy to lift, for example using a lifting device. As a result, the contacting of the cooling plates and the container can be produced in a particularly simple manner.
  • the holding devices do not necessarily have to be in the form of projections.
  • the containers are each arranged next to one another in the hollow body.
  • the containers can be held using clamps or other fastening devices, which can preferably be moved using rails.
  • the projections can be arranged parallel to a direction of introduction for the containers.
  • the hollow body can preferably be made of a heat-insulating material in order to make the cooling as efficient as possible.
  • This also has the advantage that the frozen material in the containers remains in a frozen state by itself for some time, even after the cooling plate arrangement has been deployed. This makes it particularly easy to bridge periods of time in which further temperature control is not immediately possible, for example to take the carcass to a refrigerated warehouse or to a carry out the actual transport immediately in special cases. In the applicant's tests, two hours could easily be bridged before the goods were transported to a temperature-controlled store.
  • the body itself can also be used to transport the containers.
  • the body can rest, for example, on a pallet that is particularly easy to move using the storage technology that is available in most cases.
  • the containers can be thermally insulated for controlled freezing in accordance with the unpublished Austrian patent application A 50778/2017 result.
  • the containers arranged in the body can preferably rest on the projections via extensions, which can increase the distance over which the containers are to be lifted in the body, in that the extensions are made significantly thinner than the container itself.
  • a movement device can also be introduced into the hollow body in order to move the cooling plates in a particularly simple manner in order to establish contact.
  • a free space for the movement device to be brought in and taken out can be provided in the hollow body.
  • Cooling plates 2 of the cooling plate arrangement 1 protrude freely from the carrier 3, the cooling plates 2 being mounted in such a way that they are accessible on three sides.
  • the cooling plates 2 are each individually, or all at the same time, parallel to the height, so that the distance between the cooling plates 2 can be changed individually or all distances together.
  • the structure involves at least two cooling plates 2 that are parallel and height-adjustable, but in most cases it can be assumed that between 5 and 10 cooling plates 2 will be used.
  • This cooling plates 2 transfer the cold or heat directly to the material to be frozen or thawed.
  • the cooling and heating capacity for the plate supply can come from a unit (device 7) connected to the carriers 3 .
  • the device 7 can be integrated into the carrier 3 or designed separately thereon.
  • the cooling plates 2 can be made of aluminum, copper, or preferably made of stainless steel.
  • the energy is transferred to the cooling plates 2 with brine, glycol dilutions or preferably silicone oil as the temperature control medium.
  • the freezing temperature can reach as low as -20°C, but in most cases in practical use it is preferably between -50°C and -80°C.
  • the containers 8 are containers or housings as in the international application WO2018129576 are revealed.
  • the (single-use) bags are in a shell (housing), which is equipped with a foam on the edge and in the hose area, which absorbs the volume expansion of the liquid during the freezing process and then hardens. This immobilizes the filled-frozen-expanded sac, thus preventing it from moving in any frozen state. This is advantageous as movement of the plastic materials would lead to breakage.
  • Fig.1b corresponds to that of Fig. 1a , but is a side representation.
  • 1c represents an alternative embodiment of the storage of the cooling plates 2 on the carrier 3.
  • Figure 2a The goods to be frozen/thawed are located in a body 10 made of heat-insulating material and having a hollow body 5 .
  • This can consist of foam material, plastics or fiber composite or composite materials.
  • the function of the same is to give stability to the primary packaging (container 8), to allow robust logistics and to isolate the interior from external agents (UV, temperature, humidity, access, etc).
  • this body 10 there are several containers 8 mounted one above the other, which are to be frozen/thawed. These individual containers 8 each rest on a projection and can be moved upwards individually. These projections form the holding devices 9. After the force that pushes them up has ceased, the individual containers automatically return to the lower rest position due to gravity.
  • the body is completely closed, is located on a load carrier, preferably a pallet, and has an opening 4 to insert the cooling plates 2 and to convey liquid in and out. This is preferably, but not exclusively, done with sterile connectors (e.g. CPC Colder ASQG).
  • sterile connectors e.g. CPC Colder ASQG
  • Figure 2b is equivalent to Figure 2a , but is a front view of the body 5.
  • the extensions 11 with which the containers 8 are seated on the holding devices 9 designed as projections can be clearly seen.
  • the cooling plates 2 are in their lower, resting position.
  • the container 8 in the body 10 as well.
  • the two assemblies (cooling plate arrangement 1, body 10) can be moved together manually, but preferably automatically ( 3 ). This is made possible, for example, by the distance between the individual containers 8 being greater than one Plate thickness, ie an extra distance is also available so that the merging is possible.
  • This is done in that the bottom cooling plate 2 is raised.
  • This is done with a direct plate drive (movement drive 6), preferably with its own force transmission, preferably a scissor lift or a lift under the lowest cooling plate.
  • the cooling plates 2 and containers 8 are pushed upwards until the uppermost container 8 exerts pressure on the uppermost cooling plate 2. This ensures that the entire compression cascade has been completed and that there is contact between the cooling plate 2 and the container 8 at every point.
  • the end point of this process is a compressed pack of cold plates 2 and containers 8. This is then frozen and/or thawed, preferably in an automated manner.
  • the contacting process can run backwards, then the containers 8 and the cooling plates 2 are lowered back to the respective lower resting point and can be separated from one another easily, preferably automatically.
  • On the body 10 over the opening 4 is then a - preferably heat-insulating - attached cover to protect the interior.
