Caustic soda (sodium hydroxide) is a highly caustic and reactive substance. While it is commonly used for cleaning and certain industrial processes, it is not suitable for use in a UHT (Ultra-High Temperature) sterilizer at a temperature of 135 degrees Celsius.
Here are a few reasons why caustic soda should not be circulated at such high temperatures in a UHT sterilizer:
Chemical reactions: Caustic soda is highly reactive and can undergo various chemical reactions at elevated temperatures. It can react with certain metals, including stainless steel, leading to corrosion and potential damage to the sterilizer equipment.
Safety concerns: Handling caustic soda at high temperatures poses significant safety risks. The high temperature can increase the volatility and reactivity of the solution, which can lead to the release of harmful fumes or splattering. This can cause severe burns or other injuries to personnel working with the equipment.
Contamination risk: UHT sterilizers are typically used to treat food and beverage products to eliminate harmful microorganisms and extend shelf life. Circulating caustic soda at high temperatures in a UHT sterilizer can contaminate the sterilizer and compromise the safety and quality of the treated products.
If you require a sterilization process at high temperatures, it is crucial to use appropriate sterilizing agents or solutions specifically designed for that purpose. It is recommended to consult with experts or manufacturers of UHT sterilizers to determine the suitable sterilization methods and compatible solutions for your specific application.
