What is the name of this machine and what is it used for? I am looking to identify the below machine from a video I watched on youtube.

I suspect it is used somehow in the process of making ice cream.

I was looking in the pasteurizing category without any success.

Any idea?

Thank you!!
It looks like it's just a commercial version of the machine we normally call an ice cream maker.

Even some of the home machines have a similar armature structure to hold the motor over the mixing container:



Its function is to stir the mixture as it freezes to aerate it and prevent large ice crystals from forming.
