What are the ice-making principles and classifications of tube ice machines

A tube ice making machine is a commercial tube ice machine. It is named after the hollow tube of irregular length produced in the ice tube. Cylindrical hollow tubes with inner bores from 5mm to 15mm and lengths from 25mm to 42mm are available in various sizes. The outer diameters are: 22, 29, 32, 35mm, etc. The name of the produced ice cubes is tube ice. It has the smallest contact area and the best melt resistance among the ice types available on the market. It is suitable for the preparation and decoration of beverage products, and the storage and preservation of food ice, so it is mostly edible ice.

Tube ice is a relatively regular hollow cylindrical shape. The outer diameter is divided into four specifications: 22, 29, 32mm and 35mm. Height ranges from 25 to 60 mm. The diameter of the inner hole in the middle can be adjusted according to the ice making time, generally 5-15mm. between. Ice cubes are thick, transparent, beautiful, have a long shelf life, are not easy to melt, and have good air permeability. Daily food, vegetable preservation, fishery and aquatic product preservation, etc. Tube ice machines can be divided into small tube ice machines and large tube ice machines according to the daily output. The daily ice output of small tube ice machines ranges from 350 kg to 8 tons, and most of them are of single structure.

The daily output of large tube ice machines ranges from 10 tons to 80 tons, and most of them are composite structures and require cooling towers. The structure of the tube ice machine mainly includes an evaporator, a condenser, a water storage tank, a compressor, and a liquid storage tank. Among them, the evaporator has the most complex structure, the highest precision requirements, and the most difficult production. Therefore, only a few large industrial ice machine companies in the world have development and production capabilities.

The ice-making part of the tube ice machine is an evaporator, which consists of many vertical and parallel steel pipes. A baffle on top of the evaporator sprays water evenly into each steel pipe in a spiral fashion. The excess water is collected by the bottom tank and pumped back to the evaporator by the water pump. There is a refrigerant flowing in the outer space of the steel pipe, exchanging heat with the water in the pipe, and the closed water is gradually cooled into ice. When the thickness of the tube ice reaches the desired value, the water automatically stops flowing. The hot refrigerant gas will enter the evaporator to melt and break off the tube ice. When the tube ice falls, the ice cutting mechanism works to cut the tube ice into the set size.
