Tools and techniques for biochar production and biochar products are provided in accordance with various embodiments. For example, some embodiments include a method of biochar production that may include introducing a compound that includes at least carbon, oxygen, and hydrogen into a reaction chamber. The compound may be heated to a temperature of at least 1,000 degrees Celsius in the reaction chamber such that the compound reacts through a pyrolysis reaction to produce biochar. The produced biochar may be collected and/or further processed in some cases. In some embodiments, the compound includes at least biomass or a waste product. In some embodiments, the temperature of the reaction chamber is at least 1,100 degrees Celsius. In some embodiments, the compound has a residence time in the reaction chamber between 10 seconds and 1,000 seconds to produce the biochar. Some embodiments include biochar that may include graphite or graphene.

An excrement-drying device (1) for animal stalls, such as poultry stalls, comprises an excrement conveyor belt (2) for conveying the excrement along a conveying direction (F), wherein the excrement conveyor belt (2) extends over a conveying length (L) and has a top side (10) for receiving the excrement (K), and a drying unit (3) with at least one discharge element (4), which has at least one air nozzle (5) for blowing air onto the excrement (K) lying on the excrement conveyor belt (2) in order to dry the excrement (K). The top side (10) for receiving the excrement (K) of the excrement conveyor belt (2) is divided into several excrement conveyor belt sections (TB1, TB2) arranged one after the other in the conveying direction (F); and the at least one discharge element (4) is arranged in such a way that air is blown onto only one of said excrement conveyor belt sections (TB1, TB2).

The invention consists of a mounting plate and a cage. The mounting plate is mounted on the back of a riding mower. The mounting plate is made out of a flat piece of metal with the edges turned at right angle. The edges have openings and slots. Openings on the flat portion attach the mounting plate to the riding mower with bolts. A blower is placed in the cage. The cage is made out of four metal tubes and a platform. An attaching plate attaches the metal tubes and the platform to the mounting plate. The attaching plates have a set of opening and pins. The cage is attached to mounting plate by placing pins on the attaching plate within the slots on the mounting plate. A clovis pins is placed through openings on mounting plate and the attaching plate to hold cage on the mounting plate.

A welfare-oriented raising house for meat-type ducks, including a raising house, is provided. The raising house is internally provided with a support frame which is of a U-shaped structure and arranged in a length direction of the raising house, a raising net arranged at a top of the support frame, a cleaning and storing mechanism arranged at one end of the support frame for cleaning and storing the raising net, a traction mechanism arranged at the other end of the support frame for the traction of the raising net, blocking mechanisms which are of a zigzag structure and arranged at both sides of the support frame, and tensioning vibration mechanisms arranged at bottoms of the blocking mechanisms and fixedly connected to a side edge of the support frame.

EGGOIST multi-level floor equipment system for commercial poultry maintenance combining the advantages of poultry's free-range run with periodical automated manure removal feature of the cage housing method. The optimum dimensions of the aviary body frame are calculated as per special formulae for the length and width depending on the nest type and arrangement. EGGOIST equipment system allows to improve the microclimate parameters of the aviary, to ensure the consistently high sanitary and hygienic conditions and the lowering of egg-laying hens' morbidity rate, and to dramatically increase production rates per farmland area unit.

The invention relates to a poultry keeping facility comprising at least one nest box, a first colony surface having a perforated first floor area and a second colony surface having a second floor area for spreading litter. According to the invention, a perch facility having at least one perching rod is arranged at a height above the first or second floor area. The perching rod is movable relative to the first or second floor area, wherein the perching rod is movable from a first position to a second position in which the perch facility covers a smaller area of the first or second floor area than in the first position.

A system for harvesting nitrogen, comprising a motored robotic litter processing vehicle including an elongate housing creating an inner space for mounting components. A nitrogen harvester box connected to a rear portion of the vehicle is provided including a vacuum canopy connecting four sides to a floor, and wheels. A scoop level to ground having an opening facing the vehicle is enabled to collect litter material including nitrogen. A sieve screen having a mesh size positioned laterally at a height above the floor enables nitrogen particles smaller than the mesh size to fall through the sieve and nitrogen particles larger than the mesh size to be captured on a top surface of the sieve, wherein a vacuum chute collects the particles smaller than the mesh size and deposits them into a collection bin.
