How to Choose Evaporators in IQF Tunnel Freezers

IQF tunnel freezers are used in the food processing industry to quickly freeze food items individually, allowing them to maintain their shape and texture. These freezers use a conveyor belt system to move food items through a tunnel where they are rapidly frozen by a stream of cold air.

The cooling coils in an IQF tunnel freezer are responsible for generating the cold air that freezes the food items. These coils are typically made from aluminum or stainless steel and are designed to withstand the low temperatures required for the freezing process.

Aluminum cooling coils are a popular choice for IQF tunnel freezers due to their high thermal conductivity, which allows them to quickly cool the air passing through them. However, aluminum coils are prone to corrosion and can be difficult to clean, which can impact the hygiene of the freezing process.

Stainless steel cooling coils are an alternative to aluminum coils that offer greater resistance to corrosion and are easier to clean. The smooth surface of stainless steel coils also helps to prevent the buildup of ice on the coil, which can impact their effectiveness over time.

These Stainless steel evaporators are designed to withstand the harsh conditions of the freezing process and maintain a high level of hygiene.

The stainless steel construction of the evaporator ensures that it is resistant to corrosion and can withstand the low temperatures required for freezing. Additionally, the smooth surface of the stainless steel is easy to clean, making it ideal for use in the food processing industry.

IQF tunnel freezers work by rapidly freezing food items individually, allowing them to maintain their shape and texture. The evaporator is a critical component of this process, as it is responsible for cooling the air that circulates around the food items. The stainless steel construction of the evaporator ensures that it can effectively cool the air and maintain a consistent temperature throughout the freezer.

Overall, a stainless steel evaporator is a reliable and durable solution for IQF tunnel freezers. Its ability to withstand the harsh conditions of the freezing process and maintain a high level of hygiene make it an ideal choice for the food processing industry.
