Food grade silicone tubing can be sterilized at high temperatures. This type of silicone tube is mostly treated in the same way and undergoes a strict disinfection process before use. The temperature of disinfection is a key step, as silicone tube products require specific temperature conditions to ensure disinfection effectiveness without damaging their material.
Specifically, food grade silicone tubing can be disinfected using hot air at+250 ℃ (or+482 ℃ F) or steam at+135 ℃ (or+275 ℃ F) at a pressure of 3.5 bars for 1.5 hours. After a disinfection, it is necessary to wait for a period of time (such as one hour) for the hose to return to a stable state, as steam can alter the organic matter and expansion properties of the silicone elastomer.
In addition, when using steam disinfection, attention should be paid to the accumulation time. If the accumulation time of steam disinfection exceeds 150 hours, carefully check whether the silicone tube can continue to be used, as the fittings may change after exceeding the recommended disinfection life.
After disinfection, if the food grade silicone tube is not used temporarily, it should be cleaned and placed on a dry shelf to avoid exposure to sunlight and ozone environment, and to avoid contact with chemicals. To ensure that there is no dust or harmful substances inside the storage, the head and tail of the silicone tube can be bent and rolled up at a temperature of 45 ℃ or 90 ℃.
