The most common ice factories are edible ice and industrial ice factories. For the selection of an ice plant, many factors need to be considered, such as: investment cost, operating cost, maintenance cost, water supply and preference for ice type. Ice-making manufacturers must design and manufacture ice cubes that can meet the needs of the local market under the existing equipment. Whether it is a new ice factory or an old ice factory, only by controlling lower costs can they be more competitive in the local ice-making market.
