  • Patent number: 10780374
    Abstract: A system for recovery of animal byproducts and providing water reuse from an animal processing plant waste stream. In one embodiment of the invention there is an equalization tank forming part of an animal processing plant that is mechanically filtered to recover animal byproducts from a water mixture in the equalization tank. In another aspect of the invention there is a skimmer tank that contains a skimmer mixture with water and animal byproducts. The system mechanically separates the animal byproducts from the skimmer mixture in a manner that is suitable for human consumption. The system also allows the separated water to be reused in the animal processing plant.

  • Patent number: 10525380
    Abstract: A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture. A contaminate tank receives a supply of the fluid mixture containing contaminate from a source such as a manufacturing line where overspray of paints or cleaning solutions containing washed away oils are collected. A free floating weir floats on the surface of the contaminate tank and mechanically separates and removes contaminate from a surface of the contaminate tank and concentrates contaminate in a consolidation tank. The free floating weir is equipped with several features that enhance the ability of the free floating weir to remove contaminate without becoming clogged.

  • Patent number: 6761820
    Abstract: A paint overspray particulate filtration system includes a collection tank, a floatation consolidation tank, and a vacuum filter assembly having a filter medium that traverses a pair of vacuum chambers. A positive displacement vacuum producer for the first vacuum chamber discharges a first supply of pressurized air at a temperature preferably greater than about 170° F. and a pressure preferably greater than about 6 psig, while a centrifugal compressor discharges a second supply of pressurized air at a temperature of perhaps up to 110° F. and at a pressure of perhaps 4 psig. The first pressurized air supply is heat exchanged with the second pressurized air supply, whereupon the cooled first pressurized air supply is directed through a submerged diffuser nozzle to aerate the collection tank and/or the consolidation tank. The warmed second pressurized air supply is directed onto the paint sludge carried atop the filter medium to enhance sludge dewatering.

  • Patent number: 6395091
    Abstract: The present invention is generally directed to various systems and processes for applying feed additives to a solid feed composition. In one embodiment, a solid feed additive is combined with a liquid carrier to form a feed additive suspension. The feed additive suspension is fed to a dispensing device that sprays the suspension onto a solid feed composition stream. In an alternative embodiment, a system is disclosed that combines and/or dilutes various liquid feed additives that are then similarly sprayed on a solid feed composition stream. In various embodiments of the present invention, the system includes a plurality of submixing systems that not only maintain a homogeneous suspension or solution but are also capable of continuously applying the solution or suspension to the feed composition.

  • Patent number: 6199512
    Abstract: A method for orally administering feed supplements to a plurality of animal feed stations, and an apparatus for accomplishing the method are disclosed. A feed reservoir is separately connected to the feed station via a tube and is dispensed into a feed trough through a plurality of spray nozzles, providing essentially unlimited supplemental feed. The apparatus also comprises separator plates, such that individual feeding stations result. Additionally, a method of disinfecting and rinsing the apparatus is provided.
