摘要： Wort is continuously supplied to a circuit including an elongated closed channel and through which micro-organisms are fed. After fermentation has taken place in the circuit, the mixture of wort and micro-organisms is centrifuged to separate it into fermented wort, a living cell mass and impurities, these three components being separately discharged from the centrifuge. The separate discharges of fermented wort and living cell mass are continuous, and the latter discharge includes an excess of living cells formed in the circuit, an amount of cell mass corresponding to this excess being discharged from the circuit.

摘要： The disperse phase of an emulsion is coalesced by passing the emulsion through a bed of bodies located between an inlet and an outlet and which are wettable preferentially by the disperse phase. The emulsion is caused to flow through the coalescence bed while allowing mutual movability of the bodies, the entire bed being situated within a space which is completely filled by the flowing emulsion.

摘要： The frame and cover have supporting surfaces engageable by a hose in an expanded condition thereof to lock the cover in its closed position. Control means are provided for maintaining the hose filled with fluid to hold it in its expanded position, such means being operable to discharge fluid from the hose so that it contracts to a condition in which said supporting surfaces permit movement of the cover to an open position.

摘要： Sludge is discharged intermittently from the centrifugal rotor under control of a hydraulically actuated piston valve movable axially of the rotor. The piston valve has a radially inner area facing the rotor''s separating chamber and partly defining a space within the rotor, and means are provided for maintaining this space free of liquid and thereby reducing the hydraulic pressure tending to shift the piston valve to its sludge-discharging position.

摘要： The peripheral wall of the pump chamber includes a surface of revolution having its axis coinciding with that of the pump rotor, the latter being provided with radial vanes cooperating with said peripheral wall to divide the chamber into a suction side and a pressure side. A diaphragm having an inner surface forming part of said peripheral wall is urged against the pump rotor by an air cushion enclosed in a space defined by the diaphragm and a bowl seated against the diaphragm''s outer surface.

摘要： A barrier is mounted at one end for pivotal movement about a generally horizontal axis parallel to the length of the enclosure and can be swung on this axis between a closed position, wherein the barrier extends transversely across the enclosure, and an open position where it is clear of the enclosure. A rod extending parallel to the length of the enclosure is journalled for rotation about its own axis and is coupled to the barrier, the rod being rotatable to open and close the barrier by means of an arm secured to the rod and extending radially therefrom at a point spaced along the rod from the barrier.

摘要： CRUDS SUBSTANTIALLY FREED FROM WHEY ARE FED INTO A VERTICAL TOWER AND EXTRUDED UNDER PRESSURE THROUGH A PLURALITY OF APERTURES IN THE BASE OF THE TOWER, AND THE CURDS ARE SUBJECTED TO A LATERAL SPREADING ACTION AND TO A LATERAL COMPRESSIVE ACTION AS THEY TRAVEL DOWNWARDLY THROUGH THE TOWER TOWARD THE EXTRUSION APERTURES. THE EXTRUDING PRESSURE MAY BE PROVIDED BY APPLYING PNEUMATIC PRESSURE TO A HEAD SPACE IN THE TOWER, AND THE EXTRUDED CRUDE MAY BE CUT INTO SEPARATE LENGTHS BY CUTTING MEANS LOCATED BELOW THE TOWER BASE.

摘要： When the rotor of a sludge centrifuge is to be emptied of its contents during operation, its peripheral sludge outlets are opened to discharge at least part of the settled sludge; and while liquid is still retained in the rotor, its balance condition is determined by a sensing means. If the latter senses a predetermined degree of unbalance at the prevailing speed of the rotor, as when sludge adheres to the rotor wall and thus fails to discharge, a suitable control is signalled to prevent complete emptying of the rotor at the prevailing speed, thereby avoiding possible damage to the rotor.
