As far as *I* am aware, there are no machines that allow you to put ingredients in one end, and finished bars come out the other. There ARE different types of milling and extruding machines that cost a great deal. But you will have to have a great deal of "raw", un-milled soap material on hand to feed into those machines, and they seem wasteful to me.
If your benefactor is looking at large scale production, he needs to know that you must start small, and build your way up. Very few things work well going all out first. He may be better off investing that money in mixers, drying racks and molds.
But you won't know until you get started, what will work best for you.
Depending on your location, you may need to inform your benefactor that starting small is in HIS best interests -- if HE sells it, HE bears the liability if someone is harmed. Besides, starting small gives him a chance to build up anticipation and interest in your soap! I suspect he is looking at machinery so he can immediately have volume -- and he needs a reliably quality product before he can up the volume. As we say here in the US, "he is putting his cart in front of his horse". (He has things in the wrong order of operation.)
fuzz-juzz, I had to laugh at your comment about English usage. I have a friend from the UK, and I discovered quickly that in the UK, US, Canada, & Oz, we may all speak "English", but we are NOT all speaking the same language!
All y'all would laugh at my Texas drawl.
Dory, I speak German, too. I bet your Viennese is different from the Tyrolese I heard in Salzburg! And trust me, only the Swiss speak Schweitzer Deutsch! I spoke in my reasonably fluent Hoch Deutsch, and they answered in English. :wink: Ganz genau!
Good Luck, waisbrod! Keep us posted.
