Embodiment 1

[0031] Embodiment 1, fructose syrup clean production process are as follows:

[0032] High fructose syrup includes the following production processes:

[0033] Blending, liquefaction, saccharification, primary decolorization, primary separation, primary concentration, isomerization, secondary decolorization, secondary separation, secondary concentration and finished syrup packaging;

[0034] Its clean production process is:

[0035] The process water used in the pulping process comes from the separation and cleaning water; the feed liquid after pulping, the feed liquid before decolorization and the feed liquid after liquefaction are heat-exchanged, so that the temperature of the pulping liquid, the feed liquid before primary decolorization, and the feed liquid before secondary decolorization is increased , cooling the liquefied liquid; the cleaning water in the detachment process is recycled except for pulping, and the regenerated liquid is recycled after being treated by mem...

Embodiment 2

[0041] The clean production process of isomaltooligosaccharide is as follows:

[0042] Isomaltooligosaccharide includes the following production processes:

[0043] Blending, liquefaction, saccharification, fermentation, decolorization, separation, concentration, spray drying and packaging of finished sugar powder;

[0044] Its clean production process is:

[0045]The process water used in the pulping process comes from the separation and cleaning water. The feed liquid after pulping, the feed liquid before decolorization and the feed liquid after liquefaction are heat-exchanged, so that the temperature of the pulping liquid and the feed liquid before decolorization is raised, and the temperature of the liquefied liquid is cooled. In addition to being used for slurry adjustment, the cleaning water is recycled. After the regeneration solution is treated by membrane filtration, the treatment solution is used for recycling. The regeneration residue, liquefaction solution residue...

Embodiment 3

[0050] The clean production process of dextrin is as follows:

[0051] Dextrin includes the following production processes: pulping, liquefaction, decolorization, separation, concentration, spray drying and packaging of finished syrup;

[0052] Its clean production process is:

[0053] The process water used in the pulping process comes from the separation and cleaning water. The feed liquid after pulping, the feed liquid before decolorization and the feed liquid after liquefaction are heat-exchanged, so that the temperature of the pulping liquid and the feed liquid before decolorization is raised, and the temperature of the liquefied liquid is cooled. In addition to being used for pulp adjustment, the cleaning water is recycled. After the regeneration liquid is treated by membrane filtration, the treatment liquid is used for recycling. The separation regeneration residue and the liquefaction liquid residue are used together to produce protein powder, and the concentrated cond...

Abstract

The invention relates to a starch sugar cleaning production technique. In the production system of the starch sugar products that takes starch as the raw material, material, heat energy and water all realize closed cycles without discharging waste material, waste water and waste heat to the environment, wherein, optimized production technique realizes no waste water discharge; waste solid is processed into protein feed; hear exchange is carried out between cold and hot materials to realize heat balance and recycling use of the interior; condensate water, cooling water and circulating water are returned to middle process after being respectively reclaimed and treated. The implement manner is that: production technique is optimized; the utilization rate of the material is improved; no waste fluid is generated in the whole process; the cleaning solution of ion exchanged enzyme and / or isomerase is reclaimed to be used for conditioning; the ion exchanged and regenerated solution is recycled after being reclaimed and treated; small amount of waste solid generated by condensation, saccharification and ion exchange is processed into protein feed. For example, in annual production of 300,000 tons of high fructose corn syrup, 90,000 tons of steam and 1.10 million tons of water can be saved yearly.

Description

technical field [0001] The invention belongs to the field of starch sugar production, and more specifically relates to a clean production process of starch sugar. Background technique [0002] At present, the production of starch and sugar has been listed as a high energy consumption, high water consumption, and high pollution industry. In traditional production, only focus on product quality and production efficiency, and the effective use of resources and the impact on the environment have not been recognized by relevant enterprises. attention. [0003] In the case of increasingly scarce fresh water resources, saving water is not only a matter of reducing product costs, but also a major event that reduces the pressure on the country's public use of fresh water resources and benefits the country and the people. [0004] Therefore, it is an urgent task to design a new clean production process of starch sugar, make full use of materials, heat energy and water resources, and ...
