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.

Method and device for the rapid solidification of aqueous substances

A sorption device for heating and cooling gas streams, with a sorbent container which contains a sorbent that takes up a working fluid which evaporates in an evaporator that contains a quantity of working fluid in correspondence with the quantity of sorbent, with a sorbent heat exchanger which exchanges the heat between a sorbent and a sorbent gas stream, with a working fluid heat exchanger which exchanges the heat between working fluid, and with a working fluid gas stream, and a closable valve between the sorbent container and the evaporator, which valve is able to interrupt the flow of the working fluid vapor, with both the sorbent heat exchanger and the working fluid heat exchanger having at their inlets and outlets connecting elements which can be readily attached to, detached from, and exchanged for one another on the gas flow channels for supplying and discharging gas streams that are to be heated or cooled.
