Abstract: A device for separating and dehydrating droppings includes a body having two walls and a bottom which includes a meshed portion and a plain portion connected to one of two ends of the meshed portion. A first shaft and a second shaft are respectively and transversely disposed between the two walls, wherein the first shaft is driven by a first motor. A loop-shaped member is reeved through the first and the second shaft and has a plurality of plates transversely disposed thereto which are moved on an upper surface of the bottom. A hydrating device is disposed to the first end of the body and includes tube with an inlet and an outlet. The tube has a screw member rotatably disposed therein driven by a motor on a first end thereof and has a cap pivotally disposed to a second end thereof. The tube further has a slotted portion defined in an under periphery thereof.

Abstract: A washer apparatus (10) includes a washing chamber (W) with a plurality of spray nozzles (N) and a pump (P1) for circulating the washing fluid (F) through the spray nozzles (N) for cleaning the contents of the washing chamber (W). A pH sensor (20) contacts the washing fluid (F) and a digital pH controller (30) connected to the pH sensor (20) generates digital pH values of the fluid (F). An acid neutralizing system (80) and an alkaline neutralizing system (90) are provided for selectively injecting acid neutralizer and alkaline neutralizer into the reservoir (S, T), respectively. An electronic controller (12) controls the operation of the washer (10) and the acid and alkaline neutralizer injection systems (80, 90) in response to the pH of the washing fluid (F) as determined by the digital pH controller (30).

Abstract: Stable (1) comprising a collection chamber (6) with a bottom (7) below a stable grid. The bottom (7) is covered by a bottom plate (9) formed by parallel V-shaped gutters (10). The walls of the gutters (10) form an angle with the horizontal, which is between 45 degees and 80 degees. At the underside the gutters (10) have a radius of 7 to 12 cm. Method for flushing a stable, manure being collected in V-shaped gutters (10), after which the bottom is flushed. The manure is discharged to a storage facility. After a certain settling time the manure has separated into a thick fraction and a thin fraction. The in fraction is drawn off and is used to flush the bottom plate clean. A layer of the thin fraction remains standing on the bottom plate (9), so that the manure is collected therein.

Abstract: An animal production building which has animal living quarters with a floor at least partially slatted with a manure deposition area beneath the slatted floor, a ventilation system which provides air motion through the animal quarters downwardly into the manure deposition area and through the manure deposited therein and outwardly of the building which processes the manure with bulking agents into a dry organic nutrient. A method of processing animal waste is also provided including the steps of providing animal quarters over a waste deposition area, depositing animal waste into the waste deposition area, removing the water from the waste, drying the waste, and mixing the waste with a bulking agent.
