ABSTRACT:
A device used for the process of tanning hides and skins is disclosed. The device comprises a cylindrical body including crosspieces of appropriate shape and in appropriate arrangement inside it. The particular features of shape and operation of said device result in an increased load of hides and skins in each operation cycle, a decrease in the requirements of chemicals applied in proportion to the load being processed, a considerable decrease in processing time, and lower water requirements.
