Abstract
A process for preparing sugar from cane by membrane separation technique is characterized by that after the cane juice is obtained, the microfilter (or ultrafilter) membrane system is used to remove impurities, gum and pigment from the cane juice. Its advantages are high purity, high output rate of sugar, and less environmental pollution.
Description
Technical field
The present invention relates to a kind of method of cane sugar manufacture, particularly a kind of method of utilizing membrane separation technique to carry out cane sugar manufacture.
Background technology
Existing cane sugar manufacture technology, comprise the pre-treatment of sugarcane, extraction of the juice, cane juice clarification, technology such as boiling-off, particularly in the clarification workshop section of sugarcane juice, in order to obtain the clear juice of clarifying syrup, need in mixing juice, add a large amount of lime and sulfurous gas (sulfurous method Production Flow Chart), perhaps add (carbonatation process Production Flow Charts) such as lime and carbonic anhydridees, like this, can produce a large amount of waste water and solid waste in sugar refining, the filter mud of generation contains a large amount of lime carbonate, is difficult to effective reuse, complex technical process, integral production efficient is low, and the sugar yield is low, and syrupy clarity is low, syrupy colourity height, quality product is difficult to further to improve, and ecotope around the severe contamination, has a strong impact on the cleaner production of sugar enterprise and further develops.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing membrane separation technique to carry out cane sugar manufacture, in order to solve the complex technical process that exists in the prior art, production efficiency is low, and the yield of sugar is low, and syrupy clarity is low, problems such as environmental pollution weight, economical effectiveness difference.
The object of the present invention is achieved like this: the cane sugar manufacture method comprises that the film separating system of employing micro-filtration or ultrafiltration carries out micro-filtration or ultra filtering clarifying to the mixing juice in the cane sugar manufacture, remove non-sugared impurity, colloid and pigment etc. in the sugarcane juice, obtain the clear juice of highly clarifying syrup, then, with the further boiling-off of the clear juice of clarifying syrup, get different high-quality sucrose products.The micro-filtration that adopts or the film separating system of ultrafiltration are: micro-filtration or ultra-filtration membrane aperture are 0.01～1 micron, and membrane material is an inorganic, and the working pressure of employing is the 0.1-1.5 MPa, and service temperature is 10～95 degrees centigrade.
Using membrane separating technology carries out cane sugar manufacture relatively has following advantage with prior art:
A. membrane separation technique is compared with prior art, and the colourity of the clear juice of syrup reduces significantly, and the clear clarification of juice degree of syrup increases substantially, and ash reduces, and improves the quality of products;
B. the syrup mixing juice can improve than the yield of existing clarification technique through the membrane separation technique clarification;
C. adopt membrane separation technique can need not to add auxiliary substances such as lime, phosphoric acid and sulfurous gas, do not contain inorganic impurity in the filter mud, can be used as feed or fertilizer application, economic benefit is obvious;
D. adopt the membrane sepn clarification technique to save multistep technologies such as once heating in the existing technology, pipeline neutralization, second-heating, continuous sedimentation, multiple-effect evaporation, syrup stove drying, shortened the technological operation flow process greatly, reduced the cost of synthetic operation, and can reduce the quantity discharged of waste water, waste residue significantly, the reduction environmental protection investments, create the good social benefit, realize the cleaner production and the Sustainable development of enterprise.
