Is the opening thumbnail photo of what appears to be a pile of chicken skins, misleading? Then what appears to be semi frozen blocks of unknown protein.
I'm confused, but if latex rubber is being made, it has that appearance in the end video, where either coloration is being added, or some sort of flavor-ent additives, and this is Jerky of some sort of ethnic consuming group, like 'Smokey-joe' beef sticks here in the states. Seems that would be a grinding and extrusion process if food manufacture. I know 'nuting'.

Differential rollers? Is that used for mixing thick materials like this sort of rubber?
