Depends on your processor size.
For small stuff, just use a plastic drum.. I use a 15 gallon poly drum and just dump KOH in through a wide mouth funnel.. I then use a piece of 3/4 pvc pipe to mix it all up.
The whole process takes about 5 minutes. You must monitor heat generation and on a hot summer day, you might have to slow down the mixing to let some heat dissipate. I don't have any fume control and since I have an open hole I'm mixing through, I do this outside.
I'm moving up to a 200 gallon processor that will require something different.. I'm thinking of pump mixing and a stainless tank to take the heat.
