Title: Chilling and ice-producing process not requiring external power supply in all phases
IPC: B61D27/00
Filed: 1994-07-24
Abstract: A cooling and ice prodn. process incorporates a capillary tube and an integral solid bed reactor with water spray, which may or may not make use of an external power supply during the formation of ice. Water is introduced into an otherwise empty prim. (1) vessel linked via a valve and tube (2) to a chamber (3) with a reactor incorporating a solid bed of hydrophilic, porous ceramic material or a material with similar properties. The water is partly evapd. in the prim. chamber (1) and vapour is partly absorbed into the integral solid bed reactor, releasing heat energy in the reactor chamber (3). The cooled residual water in the prim. chamber is converted to ice (5). The novelty is that an external power supply is not required in all phases of the cooling process.
