Description
Summary:This paper proposes a new method of ice production using a simple insulation lid and a self-contained ice production. Results of experiments in a freezer showed that ice could be produced with three proposed containers. It was possible to produce ice using a flat-plate-type simple insulation lid with the 1-ton and 0.5-ton containers. It was also proven that self-contained ice production was possible using a cap-type simple insulation lid with the 135-kg container. Outdoor experiments were also conducted. It was confirmed that ice could be produced outdoors and shown that the production method for ice intended for space cooling with a mixture of snow and water was effective. Furthermore, a method of production for high-value-added clear ice was proposed based on the outcomes of indoor and outdoor experiments. It was confirmed that all the items of the relevant standards were satisfied as a result of water quality examination of edible ice and ice intended for space cooling. •New methods of ice production using a simple insulation lid were proposed.•It was possible to produce ice using a flat-plate-type simple insulation lid with containers.•It was proven that self-contained ice production was possible using a cap-type simple insulation lid.•A method of production for high-value-added clear ice was proposed.
