Sugarcane juice contains a lot of non-sugar organic impurities, and most of the non-sugar organic impurities are suspended in the sugarcane juice in the form of colloidal particles, making the juice turbid. Flocculant is an indispensable clarification aid in the cane juice cleaning process, and its use effect will directly affect the production cost of sugar cane sugar and the quality of white granulated sugar products. This paper is based on the sulfite process of sugar production. After the sulfur smoked juice is heated, the composite flocculant is mixed with the sugarcane juice and then settled. The clear juice is taken to determine the physical and chemical indicators, and the clarification effect of the composite flocculant is investigated. The response surface method is optimized to obtain the composite The best material ratio of the flocculant is PAM 1.70ppm, CTS 1.90ppm, diatomaceous earth 2.10ppm, and the compound flocculant with the best material ratio is used for the cane juice cleaning process experiment. The orthogonal test method optimizes the cane juice cleaning process as The cleaning effect is best when the added amount of phosphoric acid is 160 ul/L, the pre-ash pH value is 6.4, and the neutralization pH value is 7.4, the obtained clear juice is clear and bright, and the color value is low.
