Question
Shalom Rabbi,
I have a question regarding kashering two machines: a granita machine and an American-style soft-serve ice cream machine, which were used only with cold products, but the products were not kosher (including non-Jewish milk, emulsifiers, and various additives), and the mixture remained in the machine for more than 24 hours (kavush ke-mevushal – "soaked as if cooked").
Now we want to kasher these machines.
We are dealing with a system of tanks and internal pipes through which the liquid passes and becomes granita / ice cream.
What is the correct method of kashering:
Is it necessary to do milui ve-irui (fill with cold water for 24 hours and empty, three times – filling and emptying three times), or is it sufficient to pour boiling water from a kli rishon (for example, from an electric kettle), or is some other method required?
What is the proper lechatchila kashering method, if it is possible to kasher these machines at all?
Thank you very much.

Answer
Shalom and blessings.
If the non-kosher substances remained in the machine while frozen or in a solid state, the halachic status of kavush (soaked as if cooked) does not apply, and a thorough washing is sufficient.
However, if they stayed there for 24 hours in liquid form, the machine requires full hagala (kashering with boiling water according to the halachic rules), and neither milui ve-rikun (filling and emptying) nor simple pouring of hot water is effective.
