A discontinuously operated centrifuge, in particular sugar or starch centrifuge, includes a rotating, cylindrical centrifuge basket having a casing provided with openings and having an upper open end. An inner screen element formed as a composite unit of a screen mat and a support mat is insertable as a prefabricated, single-piece screen element into the centrifuge basket via the upper open end thereof. The screen element has ends abutting in a circumferential direction within the centrifuge basket, with axially extending end strips attached to the abutting ends of the screen element. A closure element in the form of an axially extending clamping strip cooperates with the end strips so as to lock and radially brace the screen element against the centrifuge basket casing. Attached on the centrifuge basket is an upper limiting flange, with an annular cover being screwed onto an upper limiting flange for securing the screen element.

A separator for removing contaminants from a circulating liquid, preferably a contaminated oil, by use of centrifugal motion wherein a cylindrical chamber is mounted about a spindle serving as an axis of rotation. In-flowing contaminated liquid to be treated enters the cylindrical chamber and the base of said chamber and is directed onto distribution disk wherein it impacts a plurality of drive surfaces that impart a first source of rotational motion to said chamber. The in-flowing oil to be treated is directed against the inner wall of the cylindrical chamber, thus causing contaminant to adhere to the inner wall. As the thickness of contaminant increases on the inner wall of the chamber, the rotational speed of the chamber is reduced until it reaches a predetermined threshold speed causing a sensor to activate a signal indicating that the separator needs to be cleaned of contaminant. There is also provided a porous material at the exit where treated liquid exits and which, after a period of time, will become blocked and thus also acting to slow the rotational speed of the chamber.

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.
