Abstract

DC60 This invention provides a process for preparing granular sugar that includes (1) a sugar syrup preparation process (2) a heating and syrup process. Of evaporated sugar (3) process of sugar syrup crystallization process To obtain sugar and (4) drying, cooling and conditioning processes of sugars, purity Of sugar syrup obtained From step (1), it was adjusted to a range of 87.0 to 95.1% by weight. Before step (2), the crystallization of the sugar syrup was performed with a strong shear force to enter to Resulting in granulated sugar And step (4) is carried out in a method by obtaining granulated sugar from step (3) that is fed and dried in the hopper through the bottom of the tank. With dry air Blown inside This invention provides a process for preparing granular sugar which consists of (1) a syrup preparation process (2) a heating and syrup process. Of sugar evaporation (3) syrup crystallization process to obtain sugar and (4) drying process. Cooling And sugar conditioning in the process Pure The syrup obtained from step (1) was adjusted to a size range of 87.0 to 95.1% by weight prior to step (2). Continue with shear force to fill Resulting in granulated sugar And step (4) is carried out in a way that yields the granulated sugar from step (3) that is fed and dried. In the tank through to the bottom of the tank with dry air Blown inside

Claims (9)
