I use TAYLOR LUBE grease to clean my soft serve machine but I'm considering trying H1 Belhammer instead. I want to make sure it's safe to use for heating and pasteurizing the soft mix at around 80℃, as well as for touching and consuming the mix.

H1 Bell Hammer is certified to the NSF-approved H1 standard, which defines H1 Bell Hammer as "a product that does not affect the human body if it accidentally adheres to food or other items and is then taken into the human body.
Therefore, there is no problem unless the system is intentionally touched during mixing. However, if the system is used for open bearings, etc., and there is a high possibility of mixing with H1 bell hammer, the use of H1 bell hammer should be avoided.
Also, if the operating temperature is 80°C, it can be used without any temperature problems.
