Re: Cleaning frames with steam
One thought I had was that they should screen the wax flowing out. The way they are doing it requires the wax to be reheated in order to clean it up. each time wax is heated it breaks down more. I am not sure that the screen woudl not get cooled wax built up in it though so maybe it wouldn't work. Otherwise it looks like a system that leaves a huge mess to clean up. I can't say a better idea can be hatched but this one looks like it has room for a lot of improvement. Sloping floor to the frame area so everything flows out. another chamber still heated to hold a series of screens and filters so the wax remains melted but gets reasonably cleaned and then it can flow to a container. Some attention to the ability to clean the entire mess such as screens that can be removed and dumped. finally the spout needs to go to molds that make wax ingots that are the final or nearly final product. Basically avoid the time and cost of melting the wax more than once.
As for the frames. they seemed clean to me. How clean do they need to get and what would survive the temperatures of steam. Water boils at 212 degrees Fahrenheit or 100 degrees Celsius. but steam can be as much as ten times hotter than that. In fact I was told that when water expands into steam it absorbs ten times the heat energy that it had when it reached the boiling point. that is why steam burns you instantly.
I agree that playing with steam can be dangerous. it is unforgiving of mistakes. like scars for life unforgiving. I would not want it around my grandchildren.
