Abstract (en)
[origin: WO2007128151A1] The invention relates to a device (1) for freezing, transporting and thawing fluids, in particular sterile liquids, solutions and suspensions for the chemical, biotechnology, pharmaceutical and food industries. Said device comprises a container (10) with a lid (20), a wall (40) and a base (30) and at least one heat exchanger element (50) that is operatively connected to the fluids held in the container, such that said fluids can be cooled or heated. An immersion pipe (60) is operatively connected to at least one heat exchanger element (50) via at least one sub-region of its longitudinal extension, said region preferably extending approximately from a lowest point in the container to a maximum fill level. Preferably, the immersion pipe is in direct contact with at least one heat exchanger element and can be passively heated. During the thawing process, the thus liquefied product is withdrawn via the heatable immersion pipe(s), which preferably penetrate(s) the interior of the container from top to bottom and open(s) over the lowest point in the container. In comparison to known devices, in which the feed pipe is freely located in the container interior and thus freely located in the frozen product, the advantage of the heatable immersion pipe is that the frozen product thaws extremely quickly inside the immersion pipe and the withdrawal of the thawed liquid product is only blocked in the initial phase of the thawing process. During withdrawal, the thawed product is, in addition, gently heated during its passage through the heated immersion pipe, such that it can be fed, preferably from above, onto portions of the product that are still frozen at a temperature that is significantly higher than the freezing point, thus accelerating the thawing process.
