The invention relates to a centrifuge and to a method for operating the centrifuge, especially for separating blood into solids and liquids. According to the invention, a bag (37) is used to collect the solid material discharged from the centrifuge basket (7) under sterile conditions.
摘要:
A system for recovering liquid from a liquid associated comestibles or liquid associated comestible pieces on a comestible processing line; where the system uses apparatus that comprises or includes: plural perforate rotatable bowls, each bowl with a pluggable gravity discharge opening for the comestible and each bowl with an opening to allow loading of the bowl with the liquid associated comestible from above, a collection arrangement for the bowls, or each bowl, whereby liquid centrifugally and/or gravitationally leaving each bowl, at least when each bowl is plug closed and rotating, is recovered, and a comestible receiving arrangement as part of the processing line for the comestible from each bowl. The apparatus is operated such that infeed(s) of the comestible with its associated liquid into the bowls are staggered, bowl by bowl, by at least one infeed arrangement.
摘要:
A centrifugal separator includes a cylindrical bowl having a conical lower end with an opening through which feed liquid is injected during a feed mode of operation. During the feed mode, solids separate from the feed liquid and accumulate along the inner surface of the bowl as the bowl rotates at high speed. After accumulation of the solids, the rotation of the bowl is stopped and residual liquid is drained by gravity from the bowl. In a solids discharge mode of operation, a piston of a piston assembly is urged downward along a vertical axis in response to fluid such as compressed gas or hydraulic liquid. The downward movement of the piston forces accumulated solids from the bowl via the opening in the conical lower end thereof . The solids pass from the bowl and into a passage leading to an outlet port, where the solids exit the separator.

A centrifugal separator includes a cylindrical bowl having a conical lower end with an opening through which feed liquid is injected during a feed mode of operation. The feed liquid is separated into centrate and solids, which accumulate along the inner surface of the bowl. A piston assembly includes a conical piston coupled to a piston actuator by a two-part piston shaft. During the feed mode of operation, the piston shaft is disconnected, the piston is held in an uppermost position by hydraulic pressure from the feed liquid, and a centrate valve on the piston is urged open to permit the centrate to flow out to a centrate discharge port. In a solids discharge mode of operation, the piston shaft is connected and the piston actuator urges the piston axially downward, closing the centrate valve and forcing the accumulated solids from the bowl via the opening in the conical lower end of the bowl.

A centrifugal separator provides for discharge of solids by either an axial-motion scraper or a piston/extrusion assembly. The axial-motion scraper (80) is used with hard-packed or friable solids, and includes an integral feed liquid accelerator and feed holes. The piston/extrusion assembly is used with pasty solids, and includes a piston (12) extending into a separator bowl (10) and having openings (45) permitting fluid communication across the piston. After separation is complete, a centrate valve (34) closes one end of the bowl, and the piston is moved axially in the bowl by an actuator. A bowl suspension employs a spherical mounting structure (96) and a short, spindle (98). A bearing (100) and the spindle (102) of bowl are mounted within the bearing housing. The suspension is retained by a ring and retaining member secured to the separator in compressive contact with the spherical portion of the bearing housing.

摘要:
A hermetically sealed solids discharge centrifugal separator exhibits low-shear filling, acceleration, and separation of feed material. The separator can be particularly useful for separation and recovery of sensitive solids such as chemical or biological substances. The separator accommodates disposable sample contacting elements to eliminate the need for clean-in-place and sterilize-in-place operations. Some embodiments of the separator feature dual solids discharge pistons, which fully optimize recovery of valuable solids.
