The present invention has developed, unlike a conventional technology, an apparatus and a technique for rind, inside and scrap separation, which has been the greatest impediment to the mass production of high-quality paper-making pulp, thereby enabling the production of high-quality pulp, enables produced, unbleached pulp to be used as a raw material for manufacturing industrial packaging paper because of the excellent strength of the pulp, allows bleached corn chemical pulp to be suitable for the manufacture of toilet and facial papers and tissues, and can be applied to various paper-making techniques by mixing pulps, having different characteristics, such as needle bleached chemical pulp, leaf bleached chemical pulp, and bleached chemical thermomechanical pulp (BCTMP).

A system for the continuous monitoring of wear and/or pressure within a gravity concentrator/centrifugal separator [10] is disclosed. The system may comprise a gravity concentrator/centrifugal separator [10] having a cone [30], rotor housing shell [20], and water jacket [40]. At least one detector [34] may be provided to at least one of the cone [30], rotor housing shell [20], and water jacket [40]. At least one integrated or handheld sensor [60] may be provided adjacent to portions of the gravity concentrator/centrifugal separator [10], the sensor [60] being configured to communicate (e.g., wirelessly) with the at least one detector [34] during operation of the gravity concentrator/centrifugal separator [10]. In use, the cone [30] may wear away and ultimately affect a function of the least one detector [34]. In use, pressure changes within the water jacket [40] may change and ultimately affect a function (e.g., an output signal) of the least one detector [34]. The at least one sensor [60] may be configured to monitor said function(s) of the least one detector [34]. When the at least one sensor [60] detects a change in the signal of the at least one detector [34], an operator or control system may be notified that maintenance or cone [30] replacement may be necessary; and/or an operator or control system may be notified that one or more operational inputs may need to be adjusted to obtain peak performance of the gravity concentrator/centrifugal separator [10].

The present invention provides devices and methods for concentrating a fluid and for treating a patient with the concentrated fluid. The concentrator apparatus includes a main housing (12) defining a separation chamber (14), a filter housing (48) containing a filter (46) comprising a filter element, a piping (44) for moving concentrated fluid from the separation chamber to the filter, and ports (32) for pressurizing the concentrated fluid past the filter element of the filter. The present invention also provides a variety of uses of concentrated body fluids, including autologous concentrated body fluid. The concentrated fluids can be used for example in surgical applications, including graft applications such as allograft, xenograft and autograft applications.

A machine is intended to separate the colloidal solids from a fluid by using centrifugal force. The machine has a vertical cylinder mounted at the end of a hollow shaft with sludge dispenser and clear water dispenser nozzles. The drum is rotated at high speed by a motor and pulley assembly fixed parallel. The effluent is fed to the separation chamber through the hollow shaft and the sludge is pushed out though the nozzles fixed at the periphery of the drum and clear water flows out through the nozzles fixed at the doubled chambered hollow shaft.

A centrifugal separator includes a frame and a rotating part including a spindle and a centrifuge rotor enclosing a separation space. An inlet channel provides fluid communication into the separation space and includes a rotary channel part, a frame channel part, and a first seal at the interface between the rotary and frame channel parts. An outlet channel provides fluid communication out from the separation space and includes a rotary channel part, a frame channel part, and a second seal at the interface between the rotary and frame channel parts. The inlet and outlet channels are arranged concentrically with each other. A forcing device is provided to generate a leak flow through one of the first and second seals in a first direction from the outlet channel to the inlet channel and to counteract leakage in the opposite direction.
