A system for extracting nutrients from raw manure comprises: a manure pump for transferring manure from a reception pit to a rotary cutter configured to cut fibers of the raw manure to a desired length to generate a manure slurry. The manure slurry is transferred to a preprocessing tank having an agitator for agitating the manure slurry. An infeed pump transfers the manure slurry from the preprocessing tank to a decanter centrifuge, the centrifuge having at least one solid outlet and at least one liquid outlet. A control system controls a flow of the raw manure from the manure pump to the rotary cutter, and from the rotary cutter to the preprocessing tank, the infeed pump and the decanter centrifuge, and also controls each of these elements of the system. A nutrient content of the resulting liquid centrate is reduced by at least 50% as compared to the raw manure.

An automatic cell isolation and collection system for sorting out target cells from a sample includes a crush module, a centrifuge module, a transport module, and a control unit. The centrifuge module includes centrifuge tubes and a magnetic mechanism providing a magnetically attractive force to at least one of the centrifuge tubes. The control unit electrically communicates with the crush module, the centrifuge module, and the transport module, and controls operation of the crush module, transport of the sample via the transport module after the sample is crushed by the crush module, centrifugation of the centrifuge module, and operation of the magnetic mechanism for providing the magnetically attractive force.
