  • Process to prepare natural casings in the pork butcher's trade and the device to implement it
    Patent number: 5156565
    Abstract: A process is disclosed for facilitating production of natural casings used for making pork sausage and the like where a sheath is used in association with the casings. A flat sheet with longitudinal edges, shapes, and shapes permitting the sheet to be rolled into a sheath is rolled into a sheath having a tubular shape and at least slight overlap of the longitudinal edges of the flat sheet. The casing is placed on the sheath, which permits the sheath to be put over the nozzle of a filling pusher for sausage preparation. The process allows casings to be reconstructed by wetting when applied to the nozzle. Casings do not have to be kept in salt brine. A related device is disclosed also.
