ABSTRACT:
A freezing apparatus has at least one evaporator assembly with two freezing faces in the form of large planiform surfaces. The evaporator assembly has at least one chamber portion defined by the freezing faces and an outer annulus that is connected to a substantial portion of the periphery of the freezing faces. Liquid delivery means delivers the liquid to be frozen to an overflow trough means that is mounted on the evaporator assembly so that the liquid overflows from the trough means across the freezing face. There is means for heating and cooling the freezing faces of the evaporator assembly, and the freezing faces can continuously go through a cycle of cooling so as to freeze the liquid onto the faces and heating so as to release the frost bond between the sheets of frozen liquid and the freezing faces. Recipient trough means is positioned to receive liquid falling from a liquid guide attached to the evaporator assembly, and the recipient trough means has protruding breaker portions positioned so that sheets of frozen liquid released from the freezing faces fall into contact with the portions and are broken into fragments that fall from the recipient trough means for collection. In a preferred embodiment, a multiplicity of evaporator assemblies are utilized with each assembly having a mounted overflow trough means, a separate outlet from the liquid delivery means and associated recipient trough means. Also disclosed is a method of freezing a liquid and a preferred utilization of the freezing apparatus for freezing water into sheets of ice that are broken into fragments for utilization as fragmented ice.
