Direct Answer
A steam-in-place system is a sterilization process that cleans pipes and tanks in place using high-temperature steam, without disassembly.
Key Takeaways
- A steam-in-place system is a sterilization process that cleans pipes and tanks in place using high-temperature steam, without disassembly.
- How it works: After cleaning, saturated steam is circulated through piping and tanks at sterilization temperature for a set hold time, then cooled and drained.
- Sterilizing wipe liquid blending tanks
- SIP replaces cleaning — SIP sterilizes after a separate clean (CIP) step; it does not remove soil
How Steam-in-Place System (SIP) Works
After cleaning, saturated steam is circulated through piping and tanks at sterilization temperature for a set hold time, then cooled and drained. SIP is common in wipe-liquid and sanitary production lines that require low bioburden.
Examples and Applications
- Sterilizing wipe liquid blending tanks
- Sanitizing dosing and filling lines before a new production batch
