Technical Field

The invention relates to industrial sugar production equipment, in particular to a device for removing sucrose starch and acidic flocculates in production processes of a one-step sugar production method and a two-step sugar production method.

Background

During the growth of sugar cane, both starch and sucrose are present in sugar cane as a storage component and starch content is strongly related to planting area, climate, sugar cane variety and harvest time. Starch is a high molecular condensate of glucose, with molecular weights ranging from tens of thousands to millions. The natural starch exists in a granular state, is insoluble in cold water and is in a suspension state, the natural starch absorbs water to expand when being heated, the natural starch is gelatinized to form a viscous paste when exceeding a certain temperature, and the gelatinized starch is a typical hydrophilic colloidal substance and has stable chemical properties and can not be coagulated or precipitated by a common method. The research shows that the starch in the cane juice is heated and dissolved to form sticky paste, so that the viscosity of the cane juice is increased, the filtering performance of the cane juice is influenced, the sedimentation efficiency is reduced, the crystallization of cane sugar is further hindered, the sugar boiling time is increased, the product color value and the yield of waste honey are increased, and the loss of cane sugar is caused and the quality of sugar products is influenced. In addition, the excessive content of starch in the white granulated sugar can also increase the turbidity of downstream products, generate acidic flocculate, influence the product quality and prevent sugar products from entering high-end food fields such as beverages, pharmacy and the like.

The sugarcane inevitably carries a lot of sugarcane tips and sugarcane leaves in the harvesting process, particularly after the sugarcane is mechanically harvested, the content of the sugarcane tips and the sugarcane leaves in the sugarcane is larger, starch is mainly concentrated in the sugarcane tips and the sugarcane leaves, the content of the starch in sugarcane juice is greatly increased, and the adverse effect on the sugarcane sugar manufacturing process and the obtained sugar products is generated if the starch is not removed. In the prior sugar production, starch content is usually removed by adding complex enzyme clarifiers of sugar industry such as alpha-glucanase, pectinase, amylase and the like, which are influenced by unbalanced production and operation and the like, the removal rate is not high, the complex enzyme clarifiers cannot be completely removed, the cost is high, and the production cost, the operation and maintenance cost and the like are increased; and residual amylase can have certain influence on downstream products, so that the starch content in the downstream products is changed, and the stability of the properties of the downstream products is influenced, such as the viscosity of yoghourt or starch pudding products. Therefore, when applying amylase in sugar industry of sugarcane, not only the starch removal rate is ensured, but also the residual problem of amylase in sugar products is concerned, and the extra addition of amylase is not a very ideal way for removing starch.

If a complex enzyme clarifying agent is not required to be added in the sugar production, the quality of sugar products is not influenced due to the residue problem caused by amylase, but the starch can be effectively removed through a clarifying container, the starch content in the cane sugar is reduced, the adverse influence of the starch on the sugar making process of the cane sugar and the obtained sugar products is reduced, the investment is low, the production cost is not increased, and the method is equipment urgently needed by the mechanized process of the sugar industry at present and in the future.
