Syrup clarification method using combination of active carbon and carbonic acid method

Abstract

The invention relates to the technical field of sugar manufacturing and discloses a syrup clarification method using a combination of active carbon and a carbonic acid method. The syrup clarificationmethod using the combination of active carbon and the carbonic acid method comprises the following steps: step I, adding lime milk and carbon dioxide into original syrup for saturation by the carbonicacid method to form saturated syrup, step II, adding 0.03-0.05% of active carbon into the saturated syrup for a clarification reaction to form clarified syrup, and step III, performing filtration onthe clarified syrup to form clarified and filtered syrup. The method integrates active carbon and the carbonic acid method to exert a synergistic effect; a decoloration and clarification effect of thesyrup is improved; synchronous separation of active carbon and filtrated mud is achieved through original pressure filtration due to a filtration aiding effect of calcium carbonate in the saturated syrup on active carbon; additional filtration equipment is not required; the equipment investment cost is lowered; pressure filtration equipment is additionally coated with a precoating agent, so thatcarbon leakage is effectively avoided; the filtration efficiency and filtration precision are improved; a clarification effect is good; and the method is short in technical process and high in safety.

Description

technical field [0001] The invention relates to the technical field of sugar making technology, and relates to a syrup clarification method in which activated carbon is combined with a carbonic acid method. Background technique [0002] As a big country in sugar production and consumption, my country's sugar production and consumption are increasing year by year. With the improvement of living standards, people's quality requirements for white sugar are gradually increasing. During the sugar making process, the quality of the clarification process directly affects the quality of the sugar. At present, the sugar clarification process of domestic sugar factories mainly includes the sulfurous acid method and carbonic acid method for sugar cane sugar production, and the bicarbonate method for sugar beet sugar production. However, the products produced by the sulfurous acid method inevitably have residual sulfur dioxide, and the quality of the products produced by the single ca...
