Does the Material of the Evaporator Affect the Hygiene Level of IQF Equipment?

The material of the evaporator significantly affects the hygiene level of the IQF device.

Materials such as stainless steel, with its smooth surface, is not prone to bacteria and dirt accumulation, and is easy to clean and sterilise, keeping the equipment in a hygienic condition.

Some materials, such as ordinary iron, are prone to rust and corrosion, and their surfaces can become rough, providing conditions for bacteria and dirt to accumulate, thus affecting the level of hygiene.

In the case of aluminium, for example, if its surface is not properly treated, it is prone to oxidation, and the oxidised layer formed may harbour dirt and increase the hygiene risk.

In addition, some materials may react with frozen food or chemicals in the surrounding environment to produce harmful substances, further affecting food safety and hygiene.

For example, in IQF equipment for freezing seafood, if the evaporator material is not suitable, it may lead to contamination of the seafood, affecting its quality and safety for consumption.
