Abstract: An apparatus for the continuous process of raw mixed sugar juice clarification by means of the settlement of insoluble particles and juice precipitate in a cylindrical clarifier tank that permits non-turbulent vertical subsidation and short retention time of the sugar juice in a relatively large, non-turbulent settling sector of the contents of the cylindrical clarifier tank which is maintained by the continuous rotary advancement of the raw mixed sugar juice entry and clear sugar juice and precipitate extraction station arm that rotates within and around the center of the annular shaped cylindrical clarifier tank. The rotating arm has three internal radial compartments which provide for the introduction of raw mixed sugar juice and the extraction of clear sugar juice and precipitate, in and out of the annular clarifier tank in the immediate vicinity of the respective leading and trailing faces of the rotating arm, through adjustable slots on the leading and trailing faces of the arm.

Abstract: The invention relates to a method for the continuous production of hydrolytically broken down starch or hydrolytically broken down substituted starch products such as hydroxyethyl- or hydroxypropyl starch. The invention essentially consists of carrying out most of the hydrolytic breakdown in a pipe-shaped, temperature-controlled reactor having no mixing elements. The remaining breakdown is carried out in one or more reactors fitted with mixing elements (fine hydrolysis). The product obtained can be used both in the food industry and for medical purposes, especially as plasma diluent.

Abstract: A continuous process of treated raw mixed sugar juice clarification by means of the settlement of insoluble particles and juice precipitate in a vessel that permits non-turbulent vertical subsidation and short retention time of the sugar juice. The relatively large, non-turbulent settling zone of the clarifier is maintained by the continuous advancement of the mixed juice entry and clear juice and mud extraction station which rotates within and around the annular shaped cylindrical clarifier thus permitting efficient, vertical, turbulent-free subsidation of the mud and precipitate.

Abstract: In a process for solid-liquid extraction, in particular of sucrose from beet cossettes, countercurrent extraction in an extraction tower is employed. The tower juice is drawn off together with the small-sized solid constituents obtained in the process, such as sand, essentially exclusively via side screens.

Abstract: A counterflow single-screw extractor includes a screw conveyor having a helical scroll formed from arcuate flight sections each having a plurality of elongated slots extending away from the direction of screw rotation and permitting the flow of effluent through the product and the flights in a manner controlled by the size, number, and orientation of the slots. The slots permit efficient extraction using relatively little extraction medium and at the same time permit a single-screw extractor to be used without having to periodically reverse the direction of screw rotation to unclog the slots and by the pitch of the screw conveyor. The inventive arrangement permits the use of a multi-section extractor employing different extraction media and/or different extraction media wash rates in different sections of the extractor.

Abstract: The process and the continuously working installation are intended for the extraction or flushing out of a substance from a heterogenous system with a solid phase of fibrous or granular material by means of a liquid, which, in the course of the process, forms a liquid phase which is increasingly loaded with the substance to be extracted or flushed out. The solid phase (2) is advanced in the installation with conveyor means (9. 9', 9"). the liquid phase (4, 4', 4") passes through the installation substantially in the opposite direction to the solid phase. Elements (30, 31, 32, 30', 31', 32', 30", 31", 32") for compressing and decompressing the solid phase (2) are disposed along the path of the solid phase (2) through the installation which may consist of several treatment stages (5, 5', 5") connected in series. Means for drawing off at least a part of the liquid phase are foreseen in each of the compression zones.

Abstract: A diffusion tower for sugar beet cossettes is provided with a cossettes feed-in mechanism which includes at least one, preferably a plurality, of slots in the bottom of the tower housing. Each slot extends at an angle to the radial direction and is connected to a feed device or supply conduit for supplying a mixture of sugar beet cossettes and juice into the lower end of the tower housing. A screening feed screw may be arranged to return sugar beet cossettes into the tower to thereby facilitate the juice extraction.

Abstract: An extraction tower for leaching sugar beet cossettes or comminuted sugar cane. A central shaft is rotatably supported in a tower housing. Feed advance wings for the material to be leached are secured to the central shaft with spacings between the wings. Baffle elements are secured to the inside of the tower housing so as to extend into the spacings between adjacent wings. The baffle elements are elongated plates which are secured to the housing wall at a plurality of points, preferably three points so as to simultaneously form a reinforcement of the tower housing. The baffle plates are twisted relative to a longitudinal axis so that one end of a plate has an inwardly and upwardly facing edge, while the opposite edge faces downwardly and vice versa.
