I have a Cylindrical Tank made of Stainless Steel of Diameter=1m and Height=1m.
It has been heated to ~90 degree Celsius after Steam Sanitization.
It takes usually 2 hours to cool down and come to room temperature. My aim is to reduce the cooling time significantly and have thought of following possible solutions.
1. Using a heat absorbing material, which can be wrapped around the vessel like a blanket.
2. using water on the outer surface for rapid cooling( might cause thermal stress though !!)
I want to know what are the cheap and efficient methods available for this.
Thanks in advance
