Abstract: The present invention provides a method for citrus fruit processing comprising the steps of introducing liquid citrus fruit material to be processed via an inlet to a centrifugal separator being mechanically hermetically sealed at the inlet and at the liquid outlets; separating the citrus fruit material in the separator to obtain at least a liquid heavy phase and a liquid light phase, wherein the density of the liquid heavy phase is higher than the density of the liquid light phase; discharging the liquid heavy phase via a liquid heavy phase outlet and the liquid light phase via a liquid light phase outlet of the separator; measuring at least one parameter of the discharged liquid heavy phase and/or liquid light phase, wherein the parameter is related to a concentration of the heavy phase in the liquid light phase, or vice versa; and adjusting the counter pressure of the liquid heavy phase outlet with respect to the liquid light phase outlet, or vice versa, based on the measurement in step d) so as to control

Abstract: An effluent weir system includes: one or more effluent wefts mountable within a separation tank; the effluent weir having an enclosed top portion, a bottom inlet and a discharge in fluid communication with a clear well riser; a clear well in fluid communication with the separation tank through the effluent weirs; a clear well riser with a bottom portion in fluid communication with the effluent weir discharge and a riser discharge, the riser discharge height being adjustable and including one or more sealing members. An effluent weir system may include multiple effluent weirs in fluid communication with multiple clear well risers. The effluent weir may include a peaked top portion.

Abstract: The process of producing maple syrup from maple sap can include concentrating the maple sap to a sugar content of between 30 and 50° Brix using membrane filtration, including increasing a differential pressure of the membrane filtration in accordance with an increasing of an osmotic pressure as the sugar content increases to eventually reach the sugar content of between 30 and 50° Brix; and subjecting the concentrated maple sap having a sugar content of between 30 and 50° Brix to evaporation until it transforms into maple syrup.

Abstract: The present invention relates to an improved method for the purification of crude sugar beet juice. The present invention relates moreover to methods for the manufacture of non-sucrose substance combinations from crude sugar beet juice, as well as two devices for the purification of crude sugar beet juice. The measures according to the invention allow a reduction of lime consumption during the purification.

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: A decanting vessel for separation of liquid phases of different densities. The decanter vessel is provided with several conically-shaped separation levels disposed one on top of the other and provided with openings connecting the passages, alternately at the outer periphery and at the center of the separation levels. The liquid phases are thereby caused to flow from one passage to the next, consecutively, in a generally serpentine path. Pipes are disposed in the uppermost portion of each of the separation levels to carry the lighter phase to the top of the vessel.

Abstract: A solid-liquid slurry, particularly sugar juice, is flocculated and clarified in an arrangement including a clarifier tank containing therein a mud bed of concentrated removed solids. A preflocculating vessel extends into the top of the clarifier tank and includes upper and lower chambers. The slurry is introduced into the upper chamber to flow turbulently therein, thereby deaerating the slurry. The slurry is transferred from the upper chamber to the lower chamber while the turbulent flow of the slurry is changed to a laminar flow. A flocculating agent, for example a suitable polymer, is introduced into the slurry, such that solids of the slurry coagulate as flocs in the lower chamber. The thus preflocculated slurry is introduced directly into the clarifier tank at a level beneath the surface of the mud bed therein. The liquid of the slurry percolates upwardly through the mud bed and is filtered, thus forming clarified liquid, and the flocs of solids settle downwardly into and form the mud bed.

Abstract: In a process for the production of sugar thick juice from lime-containing raw juice and wherein carbon dioxide and soda are added to the lime-containing raw juice in at least one carbonation step, and wherein the thin juice is preheated and evaporated to form thick juice, ammonia in the form of gaseous spent heating medium originating from the preheating of the thin juice is added to the lime-containing raw juice. The method of the invention results in a reduction of the consumption of soda in the carbonation step and in an increased sugar yield.
