METHOD AND APPARATUS FOR TREATMENT OF ANIMAL SKIN Russian patent published in 2005 - IPC

FIELD: leather industry.

SUBSTANCE: method involves spreading skin on respective carrier plates and introducing carrier plates with skin spread thereon into vessel; hermetically sealing vessel and creating low pressure therein; introducing liquid solution into vessel for treatment of skins to wet state; transmitting vibrations to vessel in order to provide continuous and uniform movement of treating solution contained in vessel. According to another version, method involves cleaning animal skin by introducing aqueous solution containing hydrogen peroxide and sodium hydroxide into vessel. Apparatus has number of plates on which leathers are spread, hermetically sealable vessel into which plates with skins spread thereon are introduced, device for creating low pressure in said vessel, at least one mixing reservoir for introducing therein of water and respective active substances for the purpose of producing liquid solution for skin treatment. Mixing reservoir is adapted for communication with hermetically sealable vessel, wherein low pressure is maintained for introducing therein of liquid solution, and vibratory member for transmitting vibrations to vessel for providing continuous and uniform movement of liquid solution introduced into hermetically sealable vessel.

EFFECT: reduced unfavorable effect upon environment of skin treatment procedure, in particular, elimination of necessity for utilization of chemicals, simplified, useful and compact construction of apparatus.
