A centrifugal separator includes a cylindrical bowl, a core tube assembly, and an annular piston disposed around the core tube assembly and inside the inner surface of the bowl. Feed liquid is injected down the core tube assembly into the lower portion of the bowl, raising the annular piston. During a separation mode, the bowl rotates at high speed, separating solids from the feed liquid to accumulate along the inner surface of the bowl, while collecting clarified centrate as it exits the top of the bowl and through the core tube assembly. Following solids accumulation, bowl rotation is stopped and residual liquid is pumped from the bowl. In a solids discharge mode, the annular piston is urged downward along a vertical axis in response to compressed gas. The downward movement of the piston forces accumulated solids from the bowl via an opening in the lower end thereof.

An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure (178, 240, 250) releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (172). The bowl and portions of single use structure rotate about an axis (174). A stationary inlet feed tube (184), a centrate discharge tube (212) and a concentrate discharge tube (230) extend along the axis of the rotating single use structure. A centrate centripetal pump (208) is in fluid connection with the centrate discharge tube. A concentrate centripetal pump (216) is in fluid connection with the concentrate discharge tube. A controller (274) operates responsive to sensors (264, 270) in respective centrate and concentrate discharge lines (262, 268), to control flow rates of a concentrate pump (272) and a centrate pump (266) to produce output flows of cell concentrate and generally cell free centrate.

A centrifugal filtering device includes a centrifugal drum and a rotary filter. The centrifugal drum has a receiving space for accommodating the source fluid. The rotary filter rotatably mounted in the receiving space includes a filter body and a filtrate discharge pipe. The filter body includes a filter cartridge defining a filtrate-collecting space. The filtrate discharge pipe connecting the filter body is communicative in space with the filtrate-collecting space. By rotating at least one of the centrifugal drum and the rotary filter, the source fluid is driven to generate a vortex by a centrifugal force. The centrifugal force drives the source fluid to form a heavy-phase fluid hitting the centrifugal drum and a light-phase fluid approaching the filter cartridge. The light-phase fluid passes the filter cartridge and then reaches the filtrate-collecting space as a filtrate, and the filtrate is exhausted via the filtrate discharge pipe of the centrifugal filtering device.

Implemented is an apparatus and a process for complete treatment of slurry and powder. The apparatus includes a rotatable lower bowl assembly, a rotatable upper bowl assembly adapted to be assembled with the lower bowl assembly, a drive including at least a geared motor, connected with each of the lower bowl assembly and the upper bowl assembly. A main frame assembly movably mounts the lower bowl assembly and the upper bowl assembly. The lower bowl assembly and the upper bowl assembly are assembled together to form a spherical bowl assembly in a vertical orientation, on the main frame assembly. The spherical bowl assembly receives the slurry for treatment, processes the slurry into a dried product after treatment, and safely discharges the dried product out of the spherical bowl assembly.

The botanical extraction and purification device described in this patent provide the ability to extract and purify botanical compounds from a diverse plant species through specially crafted process sequences that effectively reach the desired botanical component despite differences in botanical material types and unique differences in organic chemical characteristics. The technological package consists of two main processing centers; each is a combination of process features that can be personalized to effectively address unique extraction requirements. When combined, the extraction processes deliver capabilities in product throughput speed and product purity not available using previously available separation methods. The first component of this package is a CUP that transfers chemical compounds from botanical material into a solvent. The second component is an AISP. This device separates unwanted botanical compounds from the solvent, resulting in a relatively pure plant extract.
