Processing method for interruption of clean production of cane sugar juice

The invention discloses a processing method for interruption of clean production of cane sugar juice, belonging to the technical field of a clarification process of the sugar industry. According to the method, phosphoric acid is added into sugarcane mixed juice within 12 hours after the production interruption of the initial juicing stage of a sulfite clarification process, and the pH is adjustedto 6.5-7.5 with lime milk; after primary heating, the product is cooled to 45-55 DEG C, dextranase is added, the concentration of dextranase in the sugar juice is controlled to be 0.01-0.10U/mL, and the enzymatic hydrolysis time is controlled to be 10-30min; after the end of enzymatic hydrolysis, the sulfitation is performed, and the intensity of sulfitation is 10-16CC; sedimentation and filtration are carried out after heating and boiling, so that the clear juice is obtained. The processing method provided by the invention avoids the excessive sulfur dioxide residue caused by increase of theintensity of sulfitation a
