Abstract: A process for cold clarification of juice is described. A sugar cane or beet juice clarification process to clarify raw juice by means of deaeration of fresh raw juice, addition of milk or lime, anionic and/or cationic flocculants, particularly together with a carbonating process, addition of phosphoric acid and then passing the juice through activated carbon bed is described. The process eliminates the need to heat the juice at any stage thus making it more cost effective, energy saving and gives better yield in terms of quality and quantity both. The recycling of defecated, carbonated and phosphated filtered juice and carbonated and phosphated mud that reduces the consumption of lime, CO2 and phosphoric acid up to some extent is described.

Abstract: The invention concerns an improved method for purification of raw sugar beet juice, which is obtained by extraction from sugar beets, and to devices for purification of raw sugar beet juice. The invention further concerns a method for producing sucrose syrup or sucrose from raw sugar beet raw.

Abstract: An auxiliary apparatus for producing maple syrup from maple sap is adapted to utilize the latent heat of the steam emitted from the flue pan of a maple syrup evaporator which is fitted in sealed relation on top of the flue pan. The auxiliary apparatus is in the form of an upwardly opening pan with upright side walls and a bottom wall having a triangularly grooved inner surface and a correspondingly ridged outer surface. Steam pipes "open" at both ends thereof, extend through the interior of the auxiliary pan from a steam receiving chamber of the auxiliary pan to an upwardly opening exhaust chamber at the opposite end of the pan so that a substantial portion of the steam from the flue pan will flow through the sap in the auxiliary pan to heat the maple sap disposed therein to reduce the water content of the sap utilizing the latent heat from the flue pan. A plurality of air pipes also extend through the evaporator in parallel and closely adjacent relation to and below the steam pipes.

Abstract: An apparatus for uniformly, downwardly moving in a vessel a compact bed of solid particles in contact with a liquid. Within the vessel there is provided a rotatable lower disc which has a radially extending opening for the passage of solids therethrough. The lower disc carries a member adjacent the opening for directing solids through the opening during rotation of the lower disc. This member preferably extends above the lower disc. A system is provided to maintain the liquid within the vessel while the solid particles pass out of the bottom portion of the vessel. A rotatable upper disc having a radially extending opening may be present to distribute solids charged to the vessel onto the upper surface of the bed of solid particles.

Abstract: A method and apparatus for enhancing growth of precipitates in systems requiring separation of undesirable contaminants. Cane sugar juice, as exemplary, is introduced at an elevated temperature into an apparatus having means for separately introducing chemical treating agents, such as milk of lime and coagulants. The juice flows through a treating zone where the agents are introduced, into a holding zone and over a dispersion cone before being withdrawn from the holding zone by a siphoning means. The dispersion cone and holding zone bottom permit rapid growth of the insoluble particles while simultaneously diverting the flow direction gently so as to prevent breakup of the particles. The flow down through the treating zone, over the dispersion cone, down the conical holding zone bottom, and back up the siphoning means permits sufficient residence time for rapid growth of the insoluble particles so that coagulants need not be added in the subsequent clarification process.

Abstract: Method of treating fresh sugar juice at about room temperature which includes removing non-sugar impurities, concentrating the resulting cold, water white juice by reverse osmosis to form a syrup which is evaporated to form direct white sugar and edible molasses. Also a method of treating sugar cane juice with oxalic acid.

Abstract: Method of treating cut sugar cane, which comprises depositing the cane on a conveyor, spraying steam on the cane to melt and remove wax and field dirt on the surface of the cane, and removing the melted wax and condensed steam below said conveyor. Sugar cane juice, produced by subjecting the steamed cane to roller action, is treated with active carbon to yield a clarified juice. The clarified juice is evaporated to form direct white sugar and edible molasses. The wax is collected, purified and molded into cakes. Adding an alkaline material to the expressed juice precipitates out soaps.

Abstract: A method of, and a system for, processing or treating raw sugar juice wherein raw sugar juice produced in a crushing mill is delivered to a first section of a partitioned surge chamber from which section it is withdrawn and subjected to a degritting process in one or more cyclone separators, the juice which is relatively free of heavy solids being subsequently delivered to a second section of the partitioned surge chamber from which section it is withdrawn for clarification in a clarifier and from which clarifier mud is withdrawn for subsequent treatment in one or more centrifugal separators, the removal of heavy solids, such as dirt and grit, during the degritting process being such as to reduce wear and erosion of the components in the centrifugal separators for processing the clarifier mud.

Abstract: A method of continuous precipitation of insoluble solids formed by the reaction of a liquid solution and a reactant by hydrodynamic agitation of the solution and the reactant in a continuous hydrodynamic precipitation apparatus.

Abstract: Method and apparatus for treating fresh, unheated sugar cane juice which involves adding a sufficient amount of an aqueous alkaline slurry containing powdered active carbon to the juice to raise the pH of the juice to 6.8-8.5. The resulting mud is separated and a water white juice is obtained. The water white juice is concentrated to form a direct white sugar and an edible molasses having a natural maple flavor and odor. The juice may be subjected to a preliminary cyclone separation and the sugar cane from which the juice is obtained may be subjected to a steam-cleaning operation to remove cane wax and dirt.

Abstract: Method and apparatus for controlled growth of precipitates in systems requiring separation of undesirable contaminants from a solution prior to treatment with a coagulant aid. Cane sugar juice, as exemplary, is introduced at an elevated temperature into an apparatus having means for maintaining a mildly reduced pressure. The apparatus has a conical funnel with a downwardly extending tubular outlet. Means are provided for incrementally and continuously introducing a chemical treating agent into the juice, as it flows down the funnel toward the outlet. Juice discharge means allows for control of the retention time in the tower. The method of treating cane sugar juice is as follows. Cane sugar juice, preferably partially limed, is introduced into the top of the funnel at an elevated temperature and allowed to flow by gravity flow through the funnel, while additional milk of lime is incrementally and continuously introduced into the cane sugar.
