SS304 Bare Tube Evaporator for Ice Machine

SS304 Bare Tube Evaporator for Ice Machine

Material Advantages

Food - grade Hygiene: SS304 is a kind of food - grade stainless steel, which has no harmful substance precipitation, ensuring that the ice produced is clean and safe, and fully meeting the requirements for edible ice in the food and beverage industry such as catering.

Corrosion Resistance: Ice machines usually work in a high - humidity environment. SS304 has good corrosion resistance, and can resist the erosion of water and the chemical components possibly contained in it, avoiding the occurrence of corrosion and rust on the evaporator surface, and ensuring the service life and performance stability of the evaporator.

Structural Features

Simple and Smooth Structure: The bare - tube structure means that there are no additional complex fins or other components on the surface of the tube. The smooth surface is beneficial for the uniform freezing of water on the inner wall of the tube. In addition, it is also convenient for the removal of ice. For example, in tube ice machines, after the ice is formed, the ice can fall off smoothly or be easily cut by an ice cutter.

Reasonable Pipe Arrangement: The evaporator is usually composed of multiple SS304 stainless - steel pipes. These pipes will be arranged in a certain way, such as parallel or in a specific array mode, so as to ensure that the refrigerant flowing outside the pipes can exchange heat with the water inside the pipes evenly, improving the overall heat - exchange efficiency.

Working Principle

Heat Exchange Process: In the ice - making process, the low - temperature and low - pressure refrigerant flows outside the SS304 bare - tube evaporator. The water to be frozen enters the inside of the evaporator pipes. Due to the temperature difference, the heat in the water is transferred to the refrigerant through the wall of the stainless - steel pipe, so the water temperature gradually decreases until it freezes and forms ice.

Ice - making and Ice - removing Cycle: After the ice is formed on the inner wall of the pipe, according to the design of different ice machines, there will be corresponding ice - removing mechanisms. For example, some use the heat of the compressor exhaust to heat the evaporator to make the ice melt slightly and fall off; some rely on the mechanical action of the ice cutter to scrape the ice off the inner wall of the tube.

Performance Advantages

High Heat - Exchange Efficiency: SS304 stainless steel itself has good thermal conductivity. Through the optimized design of the pipe diameter, wall thickness and pipe layout of the evaporator, the heat - exchange efficiency can be effectively improved, which helps to shorten the ice - making time and improve the ice - making capacity of the ice machine.

Good Pressure Resistance: SS304 stainless - steel pipes have certain mechanical strength and can withstand the pressure changes during the refrigerant circulation and the water freezing process, ensuring that the evaporator will not be damaged due to pressure problems during long - term operation.
