Problems solved by technology

[0002] The waste sugar solution in the fructose syrup production process contains a large amount of polysaccharides such as sucrose, fructose and glucose and other valuable products. It has the characteristics of high COD content. If it is discharged directly, it will cause waste of resources and seriously pollute the environment; If it is processed, it will increase the production cost and cause a waste of resources.

Embodiment Construction

[0013] The present invention will be further described below in combination with specific embodiments.

[0014] Table 1: Sugar composition in waste sugar solution

[0015]

[0016] As shown in the sugar composition in the waste sugar solution in Table 1, the above-mentioned waste sugar solution adopts the waste sugar solution comprehensive utilization method in the fructose syrup production process of the present invention, comprising the steps:

[0017] Step 1 Nanofiltration separation: pretreatment of the waste sugar solution and separation by nanofiltration, sucrose, polysaccharides, divalent and above salts are trapped in the concentrated solution, and sucrose and polysaccharide solutions are recovered; monosaccharides and monovalent salts Salts enter the dialysate through the nanofiltration membrane; the purity of monosaccharides (glucose and fructose) in the dialysate is greater than 99.5%; the content of disaccharides and polysaccharides in the concentrated solution ...

Abstract

The invention discloses a method for comprehensively utilizing waste sugar liquid in the production process of fructose-glucose syrup. The method comprises the following steps of: preparing a sucrose and polysaccharide solution, a fructose solution and a glucose solution through the steps of performing nanofiltration separation, performing reverse osmosis concentration, deashing the concentrated liquid, performing vacuum concentration and the like; and completely recovering useful resources of the waste sugar liquid of the fructose-glucose syrup and recycling waste water, so that the enterprise benefit is effectively increased and the waste water treatment cost is reduced.

Description

technical field [0001] The invention relates to the field of fructose syrup production, in particular to a method for comprehensive utilization of waste sugar liquid in the fructose syrup production process. Background technique [0002] The waste sugar solution in the fructose syrup production process contains a large amount of polysaccharides such as sucrose, fructose and glucose and other valuable products. It has the characteristics of high COD content. If it is discharged directly, it will cause waste of resources and seriously pollute the environment; If it is processed, it will increase the production cost and cause a waste of resources. Contents of the invention [0003] The object of the present invention is to provide a method for comprehensive utilization of waste sugar liquid in the fructose syrup production process which can effectively recycle useful resources in fructose syrup waste sugar liquid and simultaneously enable waste water to be reused. [0004] I...
