What is the purchasing difference between semi-automatic and fully automatic slicers?

With a semi-automatic slicer, an operator loads and unloads; a fully automatic model adds powered feeding, counting, stacking or conveying, which is where the price gap comes from. Estimate daily slicing volume and labor hours first, then judge the payback—blade speed alone misleads, since loading and re-stacking are usually the real bottleneck. Calculate effective hourly output across the full load-slice-unload-changeover cycle. Anchor the quote to trials on your own product under continuous running, including slice integrity, and put those figures in the technical agreement so later configuration changes need written sign-off.
