Anyone know what this kitchen appliance does?

We cleared our kitchen cupboards,
Their contents to assess,
And found a strange appliance:
What it does we cannot guess.

This "thing" was made by Bauknecht
And, it seems, was rarely used.
We examined its components,
And they left us quite confused.

We checked on sundry retail sites.
Our gizmo can't be found.
It's a processor of some sort,
As a motor drives it round.

It contains a sort of basket,
In a top which has a spout.
There's a funnel (used to feed stuff in?)
But what on earth comes out?

There are sadly no instructions.
The machine was in no box.
And, until we find its purpose,
It will only serve to fox.
