Sugar-juice syrup floating clarification process used in carbonation method

Abstract

The invention discloses sugar-juice syrup floating clarification process used in carbonation method. The sugar-juice syrup floating clarification process comprises two processes, namely, a preparation process of crude syrup and a preparation process of white granulated sugar, wherein the preparation process of crude syrup comprises ten steps, namely, primary heating, first carbonation, secondary heating, filtering and the like and the preparation process of white granulated sugar comprises five steps, namely, secondary sulfitation, sugar boiling, crystallizing, crystallization promoting and honey separation. Since the syrup floating impurity removal process added in the traditional sugar production process by virtue of the carbonation method, high-quality materials are provided for material boiling in each section of the subsequent sugar boiling so that the product quality is improved, brown granulated sugar remelt syrup can be treated at a certain ratio, the colloid and impurities in the remelt syrup can be effectively removed, the honey production factors are decreased and thus the viscosity of the material is reduced and the boiling of various sugar pastes and sugar recovery are facilitated.

Description

technical field [0001] The invention relates to the technical field of sugar juice syrup clarification. Background technique [0002] White sugar is processed from plants such as sugar cane or sugar beet. It is the main product of sugar factories. Its main component is sucrose, which is an important daily condiment and widely used in food processing, beverages, pharmaceuticals and other industries. The traditional and mature processing methods for producing white sugar in my country mainly include carbonic acid method and sulfurous acid method. Compared with carbonic acid method and sulfurous acid method, the process equipment is more complicated, the amount of detergent is more, the energy consumption is higher, and the cost is higher. There are many non-sugar impurities, the recovery rate of cooking is high, the quality of white granulated sugar is good, the color will not increase after long-term storage, and the residual sulfur dioxide content is high. The process of tra...

Problems solved by technology

[0005] For example [Patent No.] CN200910114022.X discloses "an improved process for clarification by carbonation of sugar juice". Lime and carbon dioxide are used as the main clarifiers, and the processes of heating, ashing, filling, filtering, and sulfur bleaching are adopted. Calcium-based sediment to remove various non-sugars, first add milk of lime or calcium hydroxide to the juice to be clarified to pH 10.8-11.8 to obtain lime juice; then use carbon dioxide gas for the first full filling to pH9.7- 11. Solid-liquid separation to obtain a clear juice; then use carbon dioxide gas for the second full filling to pH 7.8-8.4 to obtain a carbon dioxide juice, neutralize the carbon dioxide juice first, then heat and then filter to obtain a clarified juice, only using calcium carbonate as the The main sediment removes all kinds of non-sugar, and the impurity removal effect is not good

[0006] For example, [Patent No.] CN200910192052.2 discloses "a low-carbon and low-sulfur sugar juice clarification method". In this method, the sugar juice is first added with milk of lime to a pH of 6.0-9.5, and then pumped to a heater for heating to 50-80°C , into the progressive liming device, add milk of lime to pH 10-11, so that a large amount of impurities are condensed and precipitated, then milk of lime is added again, and then pumped into the carbonation charger, carbon dioxide is inhaled to produce a chemical reaction to form calcium carbonate precipitate, and a large amount of impurities are removed by adsorption , and make the pH reach 8~9, enter the advection fast settler to separate the clear juice, then pump it to the sulfur fumigation neutralizer, inhale sulfur dioxide and neutralize it to pH 7.2~7.8, and enter the In the sedimentation tank, high-quality clear juice is separated and sent to the subsequent process. The mud juice obtained from the above two precipitations is mixed and filtered to separate into clear juice and filter mud. Only carbon dioxide is used to produce chemical reactions to form calcium carbonate precipitates to absorb and remove impurities. The effect of removing impurities is not good. good
