A suggestion, make the loading ramp out of angle or bend a bit of metal. - It'd be less likely to catch fire than the wood.
Other than that it looks fine.
Autofeed from a hopper is fine, but costs more to make & timing of the feed rotation is needed. Plus if it's auto there is a tendency for you to leave it whilst it's running with safety issues.
Plus the important bit, is that the annealing of each case is as good, repeatable and simple to operate as any more complicated machine --- Just watch your loading hand position as it is in line with the flame!
