Abstract
A filtering system used on a meat injection machine that injects pickling into meat products. The filter consists of a tank and a first and second rotary filter. The first rotary filter uses a wedge wire wound cylinder and augers having flutes that rotate to catch and push away solid particles toward the second filter. The second filter then uses more wedge wire in a whirlpool effect to ensure all solid materials and foam are in the outside of the filter. Injector fluid is then taken from the center of the inside volume of the second filter to be used in injection needles.
Claims16
A filtering system for filtering solid waste comprising:
- a first rotary filter having a first elongated filtering cylinder with a first porous outside surface, a first and second end, and an internal auger, said second end having a first gear fixed thereto;
- a tank operably connected to the first rotary filter and adapted to receive liquid from the first rotary filter;
- a pinion wheel;
- and
- a second rotary filter having a second elongated filtering cylinder with a second porous outside surface, and two ends forming an interior chamber, one of said two ends having a second gear fixed thereto, while the other end has an outlet for filtered liquid exiting said interior chamber, said second rotary filter being partially disposed within the tank and adapted to receive solid waste from the first rotary filter;
- wherein liquid having particles contained therein is introduced into said first elongated filtering cylinder and the liquid passes through the first porous outside surface, while the solid particles are transported along the length of the cylinder by said internal auger and onto said second rotary filter, said first and second gears being operably connected to said pinion wheel so that the pinion wheel operatively rotates both said first rotary filter and said second rotary filter.
