摘要:
A method and devices for the solidification of aqueous substances by the direct evaporation of water from the substance and the sorption of the water vapor in a sorption agent in a vacuum system, wherein the aqueous substance and the sorption agent are evacuated from the surrounding pressure level to a system pressure of below 5 mbar (absolute) by means of a vacuum pump and the nonsorbable gases thereby suctioned by the vacuum pump are suctioned through the sorption agent. The mass of the used sorption agent is at least half the mass of the water fraction in the substance. The solidification process is realized in less than 2 min, particularly less than 20 sec. The aqueous substance is solidified in a solidification container that can be removed from the vacuum system, the vacuum system is subsequently vented, and the solidified substance removed from the vacuum system together with the solidification container.

摘要:
A cooling element with a sorption agent, that under vacuum can sorb a vapour -like working agent that evaporates from a liquid working agent in an evaporator and with a regulator organ in a working agent vapour channel between the sorption agent and the evaporator, wherein the entire cooling element is hermetically enclosed by a gas-tight multi-layer film, the multi-layer film has a flexible construction and is under vacuum so encloses the regulator organ, the working agent vapour channel and the evaporator, that the evaporator and the working agent vapour channel remain flexible and the working agent vapour can flow to the sorption agent only through the regulator organ.

摘要:
A cooling element with a sorption agent (11, 33) that, under vacuum, can sorb a vapor working agent, which evaporates from a liquid amount of working agent in an evaporator region (16, 22), and with a shutoff device, which, before initiating the cooling process, keeps the working agent vapor from being able to flow to the sorption agent (11, 33), and where the sorption agent (11, 33) and the evaporator region (16, 22) are surrounded by a multilayer film (1, 6, 31, 32) and the evaporator region (16, 22) contains a nonwoven (5, 36) and a flexible structural material (2, 35), which together can take on a flat flexible shape under vacuum, that can be pressed onto the containers (14, 24) that are to be cooled, and the structural material (2, 35), after the start of the cooling element, can conduct the working agent vapor up to the sorption agent (11, 33) and keep a flow cross section of at least 1 square centimeter (cm2) open for the working agent vapor.
