A machine for injecting fluids into meat or fish products includes an injection head with parallel hollow needles that can be retracted by a contrast elastic device, provided to be lifted and lowered in relation to a conveyor for conveying products, each needle having an inlet opening leading into its cannula that can be located in a pressurized fluid injection chamber having a fluid inlet, the chamber being formed by a block with longitudinal ducts interconnected by ducts and a plurality of transverse ducts for the passage of the needles intersecting the longitudinal ducts, each duct including sleeves provided with seals, the block being detachable from a housing for the head and fixed by oscillating plates, one for guiding the needles and the other carrying a plurality of cylinders supplying the contrast elastic device.
- A machine for injecting fluids into meat or fish products, with at least one injection head (10) carrying a plurality of parallel hollow needles (11) that can be retracted by contrast elastic means opposite to the ends of each needle far from the tip thereof, said head being provided for being moved in a lifting and lowering double travel motion in relation to the plane of a conveyor (21) for conveying pieces of meat, each needle (11) having an inlet opening (11a) leading into its cannula that is capable of being located in a pressurized fluid injection chamber connected to means for supplying said fluid from at least one source, characterized in that said chamber, which is provided with a fluid inlet for fluid to be injected, is formed by a block (12) with several longitudinal ducts (13) interconnected by ducts (14) and a plurality of transverse ducts (15) for the passage of the needles (11) intersecting the longitudinal ducts (13), each transverse duct (15) comprising in its mouths sleeves (16) provided with seals (17), said block (12) being detachable in relation to a platform (22) of the head defining a housing and the block (12) being fixed by a first oscillating plate (18) for guiding and supporting the needles and at least by a second oscillating plate (19) carrying a plurality of cylinders (20) providing said contrast elastic means, said plates (18) and (19), in a situation overlapping the block (12), being fixed to the mentioned platform (22) of the head by fastening means (40), (41).
- The machine according to claim 1, characterized in that said plates (18, 19) are articulated to the mentioned platform (22) of the head (10) through arms (26).
- The machine according to claim 1, characterized in that the mentioned platform (22) is connected to means for lifting and lowering along upright columns (50), in relation to the mentioned plane of a conveyor (21) for step by step conveying of the pieces of meat.
- The machine according to claim 1, characterized in that the plate (18) for guiding and supporting the needles (11) has on its outer needle retaining face an auxiliary plate (27) with a plurality of openings for the passage of the needles, the thickened heads of which are supported against the outer surface of said auxiliary plate (27), this plate (27) being connected at its ends to lifting and lowering means for jointly lifting the needles a predetermined travel in relation to the injection chamber (12) so that the opening (11a) is located at the intermediate point between the seals (17) and thereby in contact with the injection chamber (12) to perform a controlled continuous injection through the mentioned needles (11).
- The machine according to claim 4, characterized in that said means for lifting and lowering the plate (27) consist of pneumatic cylinders (28) installed at two end portions of the plate (18).
- The machine according to claim 1, characterized in that said plates (18, 19) are provided with appendages (18a, 19a) with a passageway for bolts (40) to be fastened to the platform (22) by means of nuts (41).
- The machine according to claim 1, characterized in that the mentioned block (12) incorporates handles (9) at its two ends to facilitate the handling thereof.
- The machine according to claim 1, characterized in that it comprises a slab (32) of height adjustable by adjusting means (30) along a column (44).
- The machine according to claim 1, characterized in that it comprises means for detecting the thickness of the pieces of meat to be injected, comprising a flap door (33) connected to a shaft suspended with a possibility to rotate and a device (34) for detecting the angular rotation, so that when the pieces of fish or meat move forward on the conveyor (21), they move said flap door to a greater or lesser extent, providing the device (34) with information about the position in which to place the slab (32), cooperating in removing the needles (11) from the injected product.
- The machine according to claim 9, characterized in that it further comprises a hold-down plate (31) with a plurality of openings for the passage of the needles, connected by elastic means to support columns (29) lowering said hold-down plate (31) on the mentioned slab (32).
