Anyone who’s talking about removing skin, membrane, or fat is talking about the process in which on the machine there isn’t just a contact role in use, but also a specific length of knife steel. This blade has got a single sided facet and for some processes a second facet can be grinded on the opposite side of the skinner/derinder blade.
Wensing offers skinner/derinder blades for all leading brands, in any lenght or specs. When needed, the blades are also available with a safety cutout.
