Method for clarifying syrup by combining activated carbon with saccharified calcium

Abstract

The invention relates to the technical field of sugar production, and relates to a method for clarifying a syrup by combining activated carbon with saccharified calcium. The method for clarifying thesyrup by combining activated carbon with saccharified calcium comprises the following steps: preheating the raw syrup, pumping the preheated raw syrup into a stirring tank, adding activated carbon tothe stirring tank according to a activated carbon / raw syrup ratio of (0.3-10) g: 1 kg in order to obtain an activated carbon-containing syrup, adding phosphoric acid to the activated carbon-containingsyrup in the stirring tank, pumping the obtained phosphoric acid-containing syrup in the stirring tank into a retention tank, adding saccharified calcium to the phosphoric acid-containing syrup in the retention tank to adjust the pH value in order to obtain a saccharified calcium-containing syrup, and filtering the saccharified calcium-containing syrup in the retention tank to obtain a clear syrup. The method for clarifying the syrup by combining activated carbon with saccharified calcium performs the synergistic effects of the activated carbon and saccharified calcium by optimizing the characteristic parameters of the activated carbon and adopting the optimal combination mode of the saccharified calcium and activated carbon, so pigments and macromolecular impurities in the syrup are effectively removed, and the quality of the finished sugar product is improved.

Description

technical field [0001] The invention relates to the technical field of sugar production, and relates to a syrup clarification method using activated carbon combined with calcium saccharification. Background technique [0002] In the sugarcane sugar production process, the quality of cane juice clarification process directly affects the quality of raw sugar and cultivated white granulated sugar. During the refining process of raw sugar, the clarification effect of re-dissolved syrup directly affects the quality and yield of refined sugar. According to the classification of clarification process in sugar refining, sugar clarification methods can be divided into sulfurous acid method, carbonic acid method and two-step method, and the corresponding clarifying agents are mainly sulfur dioxide, carbon dioxide and lime. With the improvement of people's living standards, the quality requirements for white sugar are also gradually increasing. The traditional clarification process ha...
