Tube Ice Plant

  • Direct refrigeration through heat transfer tube resulting in less energy consumption.
  • Continuous operation of flaker’s motor across the freezing plate, resulting in high electricity consumption.
  • No moving parts in ice maker and only one cutter assembly provided for ice sizing.
  • Wear and tear of moving parts resulting in high maintenance and reduced efficiency.
  • Has in-built chilling system and does not require any external chilling plant further reducing electricity consumption.
  • Requires additional chilling plant (greater electricity consumption) to reduce inlet water temperature for rated capacity.
  • Tube ice conveyed through inexpensive screw conveyor or gravity.
  • Flake ice requires pneumatic conveyors, which is power intensive and expensive.
  • Uniform tube ice of 1" diameter, hence reduces melt age and zero lump formation.
  • The flakes lump together, forming into a snowball, which in turn creates air pocket in the concrete mixture.


The main part of the tube ice machine is the ice generator, a vertical shell-and-tube vessel surrounded by a water tank. Special water distributors on top of each tube control an even, spiral supply of water down the insides of the tubes. Excess water is collected in a tank beneath the ice generator and pumped back up to the tank at the top.

Automatic tube ice machine performs two main functions: Freezing and Harvesting. These functions are carried out in a continuous cycle and ensure the steady supply of high quality ice at a rate determined by the user.

Tube ice is formed on the inner surface of vertical tubes and is produced in the form of small hollow cylinders of about 50 x 50 mm with a wall thickness of 10 to 12 mm. The tube ice plant arrangement is similar to a shell and tube condenser with the water on the inside of the tubes and the refrigerant (Ammonia) filling the space between the tubes. The machine is operated automatically on a time cycle and the tubes of ice are released by a hot gas defrost process. As the ice drops from the tubes a cutter chops the ice into suitable lengths, nominally 50 mm, but this is adjustable. Transport of the ice to the storage area is usually automatic, thus, as in the flake ice plant; the harvesting and storage operations require no manual effort or operator attendance.

The discharge system from the plant incorporates an ice crusher, which can be adjusted to give an ice particle size to suit the customer's requirement. The usual operating temperature of this type of plant is -8°C to -10°C. The ice will not always be sub cooled on entering the store but it is usually possible to maintain the store at -5°C since the particle size and shape allow the ice to be readily broken up for discharge.

The production capacity of the tube ice machine is a function of the evaporating temperature, the temperature of the feed water and the length of the freezing cycle. Based on the price of electric power and the purpose for which the ice is to be used, the refrigeration capacity employed and the length of the freezing cycle can be chosen within very wide limits so as to achieve the most economical operation
