Embodiment Construction

[0029] Attached below figure 1 And embodiment further describe the present invention.

[0030] Take the organic sugarcane and squeeze it to get the mixed juice, prelime the mixed juice to pH6.5, heat it to 60-65℃ once, then add lime milk to adjust the pH to 11, and add 100-300ppm phosphoric acid and 1-3ppm polypropylene The amide flocculant fully reacts and separates scum in the floater to obtain clear juice and mud juice. The colloidal organic matter in the clear juice is removed by more than 50%, the turbidity is reduced from 2800IU to 870IU, and the gravity purity of the clear juice is 2.4GP higher than that of the mixed juice. Take 50kg of clear juice and use the ultrafiltration membrane experimental equipment to circulate for 10 minutes, boost the pressure to 0.4MPa and filter through the ultrafiltration membrane to obtain 38.33kg of light yellow clear and transparent filtrate and 11.67kg of light brown thick liquid. With the increase of the impurity concentration in the...

Abstract

The invention relates to a process for producing high-safety white granulated sugar. The process comprises the following steps of squeezing sugarcane to obtain a mixed juice, pre-liming the mixed juice until the pH value is 6.5, carrying out once heating on the mixed juice until the temperature is 60-65 DEG C, adding lime milk until the pH value is 11, adding phosphoric acid and a polyacrylamide flocculating agent so as to obtain a clear juice, carrying out separation by utilizing an ultrafiltration membrane system, carrying out concentration by using a nanofiltration membrane system, carrying out decoloration by utilizing anion exchange resin, carrying out desalination by utilizing cation exchange resin, and evaporating to obtain a finished product. According to the process, a low-temperature strong-base process is combined with membrane separation, membrane concentration and ion exchange techniques so as to produce sulfur-free organic sugar, so that the problems of existence of sulfur in the product, complex process procedure, low production efficiency, sugar yield and clear juice clarity, serious environmental pollution, low economic benefit and the like in the prior art are solved.

Description

technical field [0001] The invention relates to a method for producing sugar from sugarcane, in particular to a process for producing high-safety white granulated sugar. Background technique [0002] Improve the quality and safety of agricultural products. It can enhance the added value of agricultural products, meet the needs of consumers for healthy food, and is also an important measure to protect agricultural resources and the environment and realize the harmonious development of man and nature. At present, the potential safety hazards of sugar supply in some areas such as Guangxi and Yunnan still exist. The increase of sugarcane production still relies on pesticides and chemical fertilizers, and the sugar production process still needs to be improved. Relying on science and intensifying efforts to improve planting methods and production processes is an effective way to ensure the safety of sugar raw materials and sugar. At the same time, developing high-quality sugar ...
