Tube Ice Machine Features

• Tube ice machine, operates on an intermittent cycle, for example 18 minutes ice making and 3 minutes ice harvesting per cycle based on external diameter of 35mm specification ice tube;
• The internal diameter of tube ice can be adjusted according to ice making time;
• The evaporator employs SUS304 material and the heat exchange tube is designed at the most optimized thickness, combined with specialized heat treatment processing technology, which makes the best use of heat conductibility;
• Stainless steel cutters driven by gear motors are uniquely designed to produce cylindrical ice;
• High quality stainless steel for all water and ice contacting surfaces which are corrosion resistant and easy to clean;
• Tube ice machine is furnished with sub cooler, which ensures the energy efficiency of the system and gets the higher C.O.P;
• Rapid harvest and quick recovery due to hot gas defrost;
• Highly efficient Bitzer piston compressor;
• Self-diagnostic indicator light and electronic temperature controls;
• Warranty period

How Does A Tube Ice Machine Work?

01: Upper water tank 02: Water distributor 03: Water inlet to upper water tank 04: Shell 05 :Heat exchanger 06: Inside of heat exchanger 07: Reducer 08: Ice cutter 09: Water outlet to lower water tank 10: Ice water separation pan 11: Waste outlet 12: Ice outlet 13: Lower water tank

Ice making process

As shown, when refrigeration system start to operate normally, low temperature refrigerant liquid enters into shell (04) through refrigerant inlet, and it exchanges heat with water inside heat exchange pipe (06). After heat is absorbed and evaporated, it runs back to compressor through refrigerant outlet. Water in the tank (13) is pump out of water outlet (09) and delivered up to the inlet (03) of tank (01). After water goes across the distributive pipe (02), it downwardly flows along the wall of heat exchange tubes (06) and forms water film. The water then begin to exchange heat with the refrigerant outside the heat exchange tubes (05). When temperature lowers down, water freezes and ice formed inside heat exchange tubes (06)

Ice doffing process

As ice reaches a certain thickness, water route system stops circulation. Reduction gear (07) begins to run, and outside heat exchange tubes (05) is replaced by hot refrigerant gas which then melts the surface of ice. The ice harvests from heat exchange pipe (05) because of gravitational force and falls into ice cutter (08). Ice column finally is cut into 30-50mm length pieces of tube ice. Tube ice drops down and threw to ice outlet (12).
