A method and apparatus for recovering and recycling animal waste materials permits the separation of the solids with a desired moisture content from the remaining liquids and finer solid particles and wherein the liquids and finer solid particles are converted into a high quality single cell protein by means of aerobic digestion so as to maximize the value and percentage of total solids reclaimed as well as to maintain excellent sanitation and minimize odors from anaerobic decomposition. The animal waste material is delivered from the barn or other suitable collection area by aerated aerobic water onto an inclined separator screen, at which point the waste material is incrementally advanced along the screen by a combination of shuttle-driven scraper blades and pressure pads so as to cause the excess moisture or liquid together with a minimal amount of the finer solids to pass through the separator screen while advancing the rest of the material off the end of the screen and from which it may be conveyed to a separate holding area. The separator mechanism of the present invention permits a larger percentage of the finer solid particles to attach to and remain with the larger solid particles which are recovered whereby to substantially increase the total digestible nutrient value of the solid waste material removed. |

A method of separating from ruminant animal feces the undigested fibrous material that is preponderantly short pieces which consist of bundles of capillary tubes. The feces are mixed with urine, water from animal washing and preparation for milking, and with other water if needed, to form a homogeneous slurry which is run through tandem perforate drum and roller squeezers that heavily compress the short pieces to express liquid from them while continuously draining off a filtrate of liquid and fine solids which is ultimately put into a pond for use as liquid fertilizer. This leaves a filter mass which is preponderantly the short pieces. The filter mass is mixed with clean water to form a suspension which is run through tandem perforate cylinder roller pressers that compress the short pieces under several times heavier pressure to produce a cleansed filter mass and a filtrate which is combined with the original slurry. The cleansed filter mass is excellent bedding which is substantially odorless and effectively free of harmful bacteria. |

A method of treating animal wastes to reduce odors produced by the decomposition of the organic materials in the animal wastes. Contacogen particles, comprising solid catalyst particles having surface portions which are wetproofed by treatment with a hydrophobic material, are floated on the surface of a watery mass containing the animal wastes. The Contacogen particles promote the oxidation by air of the odoriferous compounds produced by the degenerative breakdown of the animal wastes. In addition, the Contacogen particles are self-renewing in that a portion of them is continually at the air interface where the oxidation takes place. Livestock manure, human sewage, and the like may be treated in this manner wherever present in a contained, open air watery mass.

A layer of poultry excrement 1-3 inches thick is dried by means of hot air to a moisture content of less than 15% with stirring by mechanical raking. Air is passed from the atmosphere through lower, intermediate and upper chambers 5, 6 and 7 with heating between the lower and intermediate chambers. In the upper chamber excrement, which has been laid by a movable hopper 26, is dried at its upper and lower surfaces while being raked by movement of a device 35 having prongs 41, some of which are reciprocated. The drying may be in four stages with different degrees of heating, raking, and air flow. In a modification, air may be passed directly to the heating means, avoiding lower chamber 5. In a further modification, air may be circulated between lower and intermediate chambers 5 and 6, avoiding upper chamber 7. |

The present invention concerns an anaerobic digestion of animal manures, energy crops and similar organic substrates. The process is capable of refining nutrients comprised in the digested biomass to fertilizers of commercial quality. The invention also provides a method for oprocessing animal carcasses or fractions thereof including meat and bone meal etc., with the objective of providing an alternative means for processing the organic waste material of animal origin while at the same time facilitating the production of fertilizers. The risk of spreading BSE prions or any other prions to animals or humans is thus substantially reduced if not eliminated. The biogas and slurry separation system according to the present ivnention is preferably integrated with the operations of animal husbandries into a total concept in which the internal and external performances of animal husbandries are optimised. The internal performances concern quality aspects related to the management of the animal houses and include industrial hygiene, animal welfare, gaseous and dust emissions and food safety. The external performances concern mainly energy production and emissions to the environment of nutrients and greenhouse gases and the sale of high quality food product. |

A process for treating liquid or semi-solid animal, including human, waste, and controlling malodor associated with same waste. The animal waste is collected into a receptacle, to form a waste pool. Particulate material which forms an interface layer over a top surface of the waste pool is introduced onto the animal waste pool floatable. The interface layer has multiple functions, based on its chemical composition and physical structure, and provides changes in the properties and composition of the upper pool layers and/or its interaction with the overlaying atmosphere. The interface layer is incubated in the waste pool for a time sufficient to yield an effect of either of the functions, while periodically, if necessary, replacing or replenishing the interface layer with new such particles. |

The invention relates to a method and a device for treating liquid manure and fermentation remains, according to the preambles of patent claims 1 and 12. To achieve the effect here that the so-called precipitation and separation of the liquid manure or the fermentation remains into a floc phase or thick phase and into a clear phase or thin phase takes place much more quickly and effectively, it is proposed according to the invention that the sedimentation tank is preceded by an upright precipitation tank, in which the liquid manure is introduced at the bottom and with turbulence, and a precipitating agent is continuously injected at the same time, and likewise at the bottom, into said turbulence of the liquid manure introduced, with the effect that the mixture of liquid manure or fermentation remains together with the injected precipitating agent rises upwards and expands in the precipitation tank, and so is discharged from the top of the precipitation tank and introduced into the sedimentation tank. |
