METHOD PREPARING MEAT MASS AND APPARATUS FOR MACERATING MEAT

摘要

An apparatus is provided for macerating meat to effect deep penetration of the meat at multiple muscle height levels for improved absorption of curing agents and improved bonding of multiple pieces of meat. The method involves feeding the meat into a compression zone where it is compressed and simultaneously engaged with multi-level maceration means which penetrate and tear the meat at two or more muscle height levels below the surface of the meat; continuously feeding the meat through the compression zone; continuously compressing and macerating the meat at multiple muscle height levels; and expelling the meat from the compression zone to allow the meat to expand to its previous dimensions so that multi-level macerated surfaces are available for bonding of the meat. The apparatus includes a macerating unit or assembly in the form of a plurality of radially slotted discs mounted on a rotatable shaft including at least a first group of such discs in combination with a second group of radially slotted discs having a diameter less than the diameter of said first group and spaced between said first discs. The macerating assembly in combination with a meat macerating apparatus is used to carry out the method of the invention. The macerated meat product produced by the method has a surface containing deeply penetrating ruptures, tears and serrations extending into two or more muscle height levels at varying depths below the surface of the meat.
