摘要:
A process and apparatus for producing a processed organic product containing organic matters having a superior nutrient balance and exhibiting high performances in water retention and gas permeation. The process involves supplying the raw material 26 containing organic fibrous substance to a reactor 1 provided therein with a plurality of main screws 6, 7 arranged side by side so as to confront the peripheral edges of the screw threads of neighboring screws with each other such that each acts to forward the reaction mixture in substantially the same direction at a velocity different from each other, effecting a biological or biochemical reaction therein while subjecting the organic fibrous substance to axial splitting and breaking by the main screws 6, 7 and taking out a processed organic product via a processed product exit port 31, which is then dewatered in a dewatering means 35 before being dried in a dryer 38 to obtain the processed product in a dried solid form.

Even in a case of an incubator having a sample rack of complicated shape, the internal environmental condition in the incubator is maintained uniformly, so that the reliability of biochemical treatment can be assured. It includes a storage box, the sample rack movably disposed in the storage box, a moving device for moving the sample rack, and a controller for controlling the moving device. The controller has a function of selectively controlling the positioning operation for positioning the sample rack at specified positions, and the agitating operation for moving the sample rack, and by the agitating operation for moving the sample rack, the atmosphere in the storage box is agitated to be uniform. Preferably, the sample rack has a plurality of sample tables coupled in the longitudinal direction.

The apparatus includes a housing having a shredding station, a blending or mixing station, a receiving chamber for receiving boxes and/or crates in a shredded state, and a decomposition chamber for receiving a mixture of the shredded organic waste and the shredded carton material. A conveyor selectively directs either the crate waste in the shredded state from the shredding station to the receiving chamber or directs a mixture of shredded organic waste and the shredded crate material to the decomposition chamber. A separate conveyor is associated with the receiving chamber to convey the shredded crate material from the receiving chamber back to the shredding and mixing station,

A domestic or small scale composter has an air tight housing (10) with an inlet (36) for compostable material such as garbage. The inlet (36) leads to a mixing chamber (12) having mixing means (32, 34) to mix the compostable material and to direct it into a composting chamber (14) for further processing. An overflow dam wall (18) is provided between the mixing chamber (12) and the composting chamber (14). Airflow is preferably provided downwardly through the composting chamber (14).
摘要:
The use of incubation means for the controlled heating of biological materials, said means comprising an electrically conducting polymer connectable to a power supply, said polymer being either contiguous or integral with an incubation vessel, or adapted to be in thermal contact with an incubation vessel. Incubation apparatus including such means and a method for culturing biological materials using them are also described and claimed.

The invention relates to a hybridization oven or incubator, and more particularly to a rotisserie and carousel/retainer system for use therein. The rotisserie includes a spindle that is readily removable from the oven, having a first end received in an annular bracket and a second end received annular bracket with an upper slot for passage of the spindle into the bracket. The carousel clip system includes a thin metal carousel plate preferably formed of a stainless steel and having a plurality of ears bent perpendicular to the carousel plate and having a detent aperture therein. A plurality of bottle retainers are removably attached to the carousel plate, the retainers having a base channel adapted to receive the ears of the carousel plate and further including a resilient arm having a detent projecting into the channel and deflectable during insertion of the ear into the channel, the detent entering the detent aperture of the ear under the bias of the resilient arm to removably retain the clip on the ear of the carousel plate.
摘要:
A digester with an agitator and a method of operating an agitator in a digester can be used, for instance, in agricultural biogas plants and communal clarification plants. The digester with an agitator and the method feature improved mixing of the waste products in the digester and enhanced digester efficiency. The digester includes a preferably round bottom surface, a filler rod and an agitator with a drive axle, preferably arranged on the periphery of the digester. The agitator is mounted in a stirring shaft or stirring pipe arranged underneath the filler standard. The method for operating the agitator in a digester involves stirring the content while material is fed into the digester through the filler standard.
摘要:
An in-vessel composting apparatus and process for continuous processing of food waste into a two component end product consisting of a bulk organic compost material and a compost-rich, liquid tea. The apparatus consists of a shredder/particle sizer feeding a horizontal drum having at least three chambers with connecting ports of sequentially increasing diameter, and through to a bulk collection container. The apparatus is further equipped with motorized drum rotation and provision for draining excess fluid from the first chamber, holding a batch volume at elevated temperature for a period of time, and then percolating it through the finished compost product in the third or final chamber to make compost tea.

The present invention is a device and method for efficient composting of organic matter using a low-cost composting structure and high efficiency methods. A composting container incorporates rigid insulated panels to form an insulated composting container of a generally cylindrical shape with polygonal cross-section. The insulated panels provide high thermal efficiency at low cost to help maintain composting temperatures. A rigid frame supports the panels and allows the container to be rotated. An internal manifold or plenum supplies air while the container is stationary or rotating. Rotation in various embodiments is effected by motor driven rollers bearing on external hoops integrated to the container support frame. In preferred methods, the container is rotated at rates slower than one revolution per minute as air is introduced.
摘要:
The invention provides a method for constructing a high resolution physical map of a polynucleotide. In accordance with the invention, nucleotide sequences are determined at the ends of restriction fragments produced by a plurality of digestions with a plurality of combinations of restriction endonucleases so that a pair of nucleotide sequences is obtained for each restriction fragment. A physical map of the polynucleotide is constructed by ordering the pairs of sequences by matching the identical sequences among the pairs.
