Abstract: An automatic machine for sterilizing, packing and sealing a meat product includes a first station (1) for sterilizing the meat product surface layer or stratum by submitting it to a thermal shock of high temperature during a very short interval (HTST technique), an apparatus (E) for feeding the meat products to the first station and a further meat product conveying apparatus (0) for withdrawing the meat product from the first station and transferring it to a wrapping position, a second station (2) for wrapping the meat product in a pre-set position including a device (57, 58) for sequentially positioning tubular containers such as bags (65) from a storage area (62) therefor to the wrapping position and opening the inlet of the tubular container for insertion of the meat product therein from the transfer device (0), a device (85, 86, 87, 88, 95) for transferring the filled tubular containers in the open position to a third station (3), and a device at the third station for vacuum sealing of the container.

Abstract: Machine for meat treatment and maceration, with automatic loading and unloading including a rotating drum having a loading and unloading hood inlet coaxial with the axis of rotation in one end, a door with fitting and locking devices for closing the drum hood inlet, driving and rolling support elements for driving and supporting the drum on a tilting frame for lifting and lowering one end of the drum articulated at the other end on a fixed structure, a series of containers surrounding the drum carried by a carriage structure for step-by-step advance movement, and a device for dumping a load in each container into a hopper for loading the drum, tilting of the frame by lifting the rear end of the drum producing unloading of the treated meat through the hood inlet into the container.

Abstract: An improved fluid injection (brine, phosphates, etc.) system for meat pieces which obviates the formation of foam by preventing air from entering the injection needles by two means: First, each multi-orificed needle is constrained to pass through an aligned duct or channel in a meat pressing block wherein is formed a discrete fluid chamber at the upper section of the duct and a close-tolerance needle guide in the bottom section. The fluid chamber is always filled with the substance to be injected, but when any of the needle's orifices are exposed to this chamber under pressure (i.e., not fully penetrated into the meat piece) the fluid chamber overflows the pressing block which triggers the shutdown of the fluid pump or pressurizer.

Abstract: A bulk meat feeding machine including a head member attached to the support base of a main feeding machine has a main feeding channel therein, the improved head member having a cavity therein connected to the outlet end of the main feeding channel, a sweeping blade rotatably mounted in the cavity, two outlet openings in the cavity connected with two spaced linear passageways having plungers therein which push the product through a bell-shaped cover attached to the head member and into alveolate form containers sealingly connectable to the bell-shaped cover. A pushing plunger is provided in the main feeding channel to push the product into the cavity and is thereafter alternately pushed through the two openings by the sweeping action of the blade driven by a rotating drive member.

Abstract: The injecting head comprises any number of needle rows, being every one of these needles connected through its top to a plunger arranged inside a fixed cylinder, integral with the head frame, being connected both ends of this cylinder to the liquid injection circuit at a constant pressure from 7 to 8 kg/sq.cm., acting the cylinder as a hydraulic accumulator that allows the coming back of the needles when they strike on an obstacle, being provided a connection through a calibrated controlling device between the two pipes which are supplying the cylinder in order to avoid over-pressures and being also intercalated in the circuit a hydraulic means which assures the keeping of an effective pressure in the top end of that cylinder. The machine includes two filtering tanks, alternately used, and a grease decantation system.

Abstract: A number n of equal receptacles, the bottom of which is a filtering screen, arranged adjacent to each other making up a circular structure which is rotated through an intermittent travel of 1/n of a full turn, with respect to a horizontal shaft in the center of the structure, in such a way that sequentially and at regular intervals, two of these receptacles, one of them positioned at the top with its mouth upwards and its bottom horizontal and the other inverted in the lower position, are at the same time faced with an unfiltered brine effluent delivered through a nozzle (the upper one) and a pressurized cleaning fluid swept against its bottom external side (the lower).
