Filtered juice clarification method by saturated filling of flue gas

Abstract

The invention discloses a filtered juice clarification method by saturated filling of flue gas. The method comprises the following steps: performing saturated filling pretreatment on filtered juice before filtered juice treatment by adopting flue gas on the basis of a sugar production process by using a phosphate-sulfite method, and performing rapid settling treatment on the filtered juice, so that partial impurities, pigments and reducing sugars are removed, and an ideal effect of the filtered juice is achieved. Meanwhile, the amount of sulfur can be reduced by utilizing the flue gas, and the scale amount generated in the subsequent process can be reduced, so that the aims of improving the purity of the clarified juice, improving the sugar boiling recovery rate and improving the product quality are achieved.

Description

technical field [0001] The invention relates to a process for cleaning cane juice from industrialized sugar cane, in particular to a method for clarification of filtered juice filled with flue gas. Background technique [0002] The sugar cane sugar production process includes two processes: sulfurous acid method and carbonic acid method. Among them, in the sulfurous acid method, since the colloid, polyphenols, iron ions and other non-sugar impurities in the sugar juice are difficult to remove, the clarification efficiency is relatively low. Carbonated sugar production process is low. Therefore, the quality of sugar products produced by the sulfite sugar production process is slightly worse than that of the carbonation sugar production process. [0003] At present, lime and sulfur dioxide are used as clarifiers in the sulfite sugar production process, and the clarification process of cane juice and syrup is completed through steps such as ash addition, sulfur fumigation, neu...

Problems solved by technology

Sugarcane sugar processing adopts environmental protection equipment to process the mud juice with a vacuum suction filter without filter cloth. The filtered juice obtained after treatment is turbid and dark in color. Most of the impurities such as filter mud have been removed, but there is still a small amount of floating mud still in the filtered juice Among them, if it is directly sent to the next process without treatment, it will affect the product quality, so the filtered juice must be treated
