Description
Technical field
The invention belongs to sugaring processing technique field, be specifically related to a kind of preparation method of health-nutrition sugar.
Background technology
External Closed Circulation in Sugar Production mode is that raw sugar is produced and sugar refinery production model, this and China directly produce arable land white granulated sugar production model certain difference, external more advanced liquid glucose defecation method has: membrane separation process, ion-exchange, membrane separation process is because juice,liming process is added a large amount of lime, phosphoric acid, flocculant, CO2/S02And high-temperature process, cause the problem such as colloidal substance stripping and increase in clarification syrup, in addition early stage membrane material industrial technology is more backward, problem, the also not continuous application demonstration in large-scale industrialization Closed Circulation in Sugar Production so far such as make that film-forming accuracy is not high, film cost is high and film use procedure decay is too fast; Sugar refinery's application is more abroad for ion-exchange, domesticly also introduces advanced ion-exchange equipment, but exists the problems such as material quality requirement is high, complicated operation, domestic sugar refinery to fail fine application and popularization.
There are two kinds of classical techniques in domestic sugar refinery to the processing of clarifying syrup, and beet adopts carbonatation process treatment process more, and this technique adds a large amount of Ca (OH) at clarifying syrup process need2、CO2, the filter mud content of organic matter that this technique produces is low, and calcium carbonate content reaches more than 80%, and without agricultural value, discharge capacity is large, has caused certain pollution to environment; At present, the most sulfurous method clarification process that adopt of cane sugar factory, this technique has the following disadvantages:
(1) production process is used SO in large quantities2, by sucrose inversion, reduce Sucrose recovery in syrup, and will inevitably make SO in white granulated sugar2Content increase, affect sugar products safety;
(2) cane juice clarification efficiency is low, and large with the fluctuation of material composition change product quality, sugar yield is lower.
The mud juice processing procedure of two kinds of techniques, need to consume a large amount of technique hot water (water consumption is generally 1.5 times of left and right of wet filter mud amount) and reduce the residual sugar amount in filter mud.
Along with cleaner production, sustainable development need, and the demand of sugar product category, particularly improving constantly of characteristic sugar, nutrient sugar demand, traditional clarification process of sugar production is subject to huge challenge, urgently find new characteristic sugar, nutrient sugar production method, to meet the needs of market development, enrich consumer's sugar demand.
China's sugar industry research work is being explored new characteristic sugar production technology always, nutrient sugar described in Chinese patent 201310048613.8 and 92104442.9 is that sugaring accessory substance molasses directly or after air float are produced and are with sweet nutrition sugar products, because molasses are through multiple high temp heating, there is larger conversion or loss in nutritional labeling wherein, still adopt classical sulfurous method in production process, product quality has certain limitation, Chinese patent (application number) 201110360967.7 discloses a kind of Using Multistage Membranes parallel production of nutrient sugar, the method of flavor cane juice and feedstuff, method separates based on membrane process, the functions such as concentrated and cold sterilization integrated, adopt Using Multistage Membranes parallel production of nutrient sugar, flavor cane juice and feedstuff, have without adding chemical agent, produce power consumption lower, can realize the maximization of commerieal sugar natural nutrition and local flavor preserves, be beneficial to the comprehensive utilization of the upgrading of sugaring products perfection and sugar material resource, although film separates, separation process is had to many advantages, but pure Using Multistage Membranes piece-rate system is limited by material clarifying treatment quality, membrane component is subject to strainability, cost performance, the problems such as film fade performance and life-span, and the problem such as expensive operating cost.
Centrifugal pressure sedimentation techniques are to utilize solid-liquid difference in specific gravity, and rely on centrifugal force field to make it to expand several thousand times, solid phase under the effect of centrifugal force by sedimentation, thereby realize Separation of Solid and Liquid, be applicable to separating containing the extraction of solid aaerosol solution, but this technology has higher requirements to equipment and technique, also do not have been reported for its clarification material distribution of tradition sugaring field etc. at present, because traditional sugar manufacturing industry adopts carbonatation process and sulfurous method production process, produce heavier calcium carbonate and calcium sulfite precipitation, apply traditional sedimentation basin and just can solve production problem, but along with the development of social life level, the people pursue nutrition, healthy product demand is more and more higher, add more auxiliary agent and obviously can not meet differentiated demand, therefore, sugaring field is in the urgent need to developing a kind of health-nutrition sugar products production method efficiently, to produce health, the product of nutrition.
