The produced ice cubes are named tube ice. The contact area is the smallest of the existing ice types in the market, the melting resistance is the best, and the ice is suitable for drink preparation, decoration, food ice storage and fresh keeping and the like, so most of the ice is edible ice. The working principle of the tube ice machine is as follows: the ice making part of the tube ice machine is an evaporator, and the evaporator is internally composed of a plurality of vertical parallel steel tubes.
