Abstract
A sugar production clarifying production line comprises a mixed juice box, a horizontal screw-type centrifuge, a first heating device, a sulfur fumigating device, a second heating device, a multi-stage ceramic membrane ultrafiltration system, and a plate-frame filter press, which are connected in sequence. During the clarification process of mixed sugarcane juice, only a little amount of limestone and SO2 is added, so the sulfur content of finished sugar is very low, and moreover the sugar has the advantages of low color value, high purity, and low ash content, and is capable of meeting the requirements of high-end customers. Furthermore, during the sugarcane juice clarification process, a ceramic membrane is used to carry out ultrafiltration and clarification; because the membrane resistance due to the scales on the ceramic membrane is small, the membrane permeation flux is large when the ceramic membrane is used to filter sugarcane juice, moreover, the decay speed of membrane flux is slow, the high membrane flux can last for a long time, thus the membrane washing period is prolonged, and the membrane washing frequency is reduced.
Description
Technical field
The present invention relates to Sugar Engineering technical field, specifically a kind of sugar clarification production line.
Background technology
China is the third-largest Chan Tang big country in the world, produces white sugar per year more than 1,000 ten thousand tons.At present, according to the difference of clarification process of sugar production, it is sulfurous method that the method for production arable land white sugar mainly contains two kinds: the first, and second is carbonatation process.Although these two kinds of methods can produce the white sugar meeting state quality standard, no matter be the weak point that sulfurous method or carbonatation process all exist more or less.Sulfurous method adds more SO in clarifying process
2as finings, cause in commerieal sugar, there be the residual of more sulphur, have some limitations for high-end customer; And carbonic acid rule needs a large amount of lime as finings, and produce a large amount of strong basicity filter muds be difficult to process, be unfavorable for ecological, environmental protective.This is also cause some domestic in the last few years sugar refinery to adopt " two step method " to produce the reason of high-quality white granulated sugar, but " two step method " technological process of production is longer, and equipment investment cost is large, and energy consumption is high, can not be widely adopted.
Along with the development of society and the continuous progress of science and technology, this physical separating process of membrane separation technique starts the extensive concern causing sugaring personage.Separatory membrane can be divided into mineral membrane and organic membrane two kinds according to the difference of its manufactured materials.Have that physical strength is large, chemical stability is high based on inorganic ceramic film, high temperature resistant, corrosion-resistant, resistance to oxidation, anti-microbe ability strong, be separated the advantages such as the high and easy cleaning of precision, therefore it is widely regarded as the mould material that the most applicable sugar industryization is produced.
According to pertinent literature, there is cane sugar factory that the clarified sugar cane juice that mixing juice (sugar cane juice) obtains successively after adding ash, coarse filtration, ceramic membrane ultrafitration clarification is sent to evaporation, boiled sugar.Ceramic membrane direct filtration sugar cane juice is obtained subsider juice by this method, eliminate sugaring process and add sulphur, add ash, the clarification operation of the series of complexes such as precipitation, thus substantially reduce whole sugar refining technology flow process, but this method still has more weak point: (1) although in this method to obtain color and luster limpid transparent, the sugarcane subsider juice that turbidity is minimum, but because ceramic membrane ultrafitration is difficult to retain the less pigment of number molecular weight, and these small molecules pigments are the pigments that a class is very easily attached to sucrose crystal surface in sugar crystal process, therefore the white sugar colour produced of this method is higher, its colour is between 500 ~ 600IU, be difficult to the requirement reaching country-level white sugar colour (≤150IU), (2) in traditional sulfurous method clarification process of sugar production, although it is also less to the clearance of coloring matter, due to the SO that it is introduced
2the effect of pigment in sugar products by redox reaction is bleached it, thus inhibit the attachment of sugaring crystallisation process small molecules pigment on sucrose crystal surface, and in syrup very easily there is Maillard reaction generation Mei Lade pigment in amino acid and reducing sugar, U.S. rad pigment is also a kind of very easily at the pigment of sucrose crystal surface attachment, and the existence of sulphur can suppress the generation of Maillard reaction, the colour of therefore traditional white sugar obtained by sulfurous method clarification process of sugar production is more much lower than above-mentioned embrane method clarification process.Therefore, the sugar that this method obtains can only be used as raw sugar, could obtain the sugar of high-quality, but this must considerably increase production cost, does not generally accept for sugar refinery through the refining of a step again.
The sugarcane subsider juice obtained to make membrane filtration can process the good white sugar of quality, in patent of invention CN 103725802A, sugar cane juice is obtained refined sugar by contriver successively after coarse filtration, the filtration of ceramic membrane essence, the decolouring of organic membrane pre-concentration, ion exchange resin desalination, MVR evaporation concentration, crystallization.Although this method can obtain the good refined sugar of quality, but it also also exists more problem: the pH value of (1) sugar cane juice is generally about 5.6, aobvious acid, contriver does not use milk of lime (or other material) by reprocessing after the pH regulator of sugar cane juice to neutral left and right, this can cause sucrose seriously to transform loss in the course of processing, thus reduces the rate of recovery of sucrose, (2) adopt organic nanofiltration or organic reverse osmosis membrane concentrated sugarcane juice, flux is less, cycles of concentration is low, easily pollute, this not only adds the time of sucrose processing, cause sucrose inversion more, and add the cost of investment of equipment, (3) ion-exchange resin decolorization belongs to essence decolouring, the colour of sugar cane juice is generally at 1500 ~ 2500IU, and colour is higher, and the load that this not only adds ion exchange resin also reduces the life-span of ion exchange resin, and resin stain is fast, regenerates more difficult, (4) specific conductivity of sugar cane juice is at 3000 ~ 6000us/cm, salinity removing in sugar cane juice can be made the load of desalination resin larger, equipment investment cost is larger, although and the specific conductivity of sugar cane juice is larger, but it is less to sugaring process influence, and great number cost need not be spent to be removed, (5) evaporation section uses steam heating sugarcane juice, after sugarcane juice is seethed with excitement, moisture evaporation, reach concentrated object, current sugar refinery generally adopts five effect pressure vacuum vapo(u)rization systems, become from clear juice the moisture that syrup will evaporate and be about 65% ~ 80%, need to consume more steam, also produce a large amount of secondary steams (juice vapour) simultaneously, these secondary steam temperature produced are also very high, for syrup heating or sugar can be boiled, therefore evaporation section is the human consumer of steam, it is again the supply station of low-pressure steam, also supply other department's hot water of sugar refinery simultaneously, therefore have the title of sugar refinery second boiler, although the five effect pressure vacuum evaporations that MVR vaporizer instead of traditional sugaring process can obtain lower vaporization temperature, thus obtain the good syrup of quality, but the temperature of MVR evaporation is lower, the pressure and temperature of its secondary steam produced is all much lower than five effect pressure vacuum evaporations, available efficiency is lower, if directly taken out with the exhaust steam from boiler cooling decompression as heating or boiling sugar vapour, energy consumption can be very high.
Therefore, if traditional sulfurous method clarification process of sugar production is coupled with membrane separation technique, before sugar cane juice enters ceramic membrane, first the pH value of sugar cane juice is adjusted to neutral meta-alkali, and then sugar cane juice is carried out low intensive stove drying, the intensity of sulfitation of sugar cane juice is made to be 4 ~ 6mL, enter ceramic membrane ultrafitration clarification again and obtain sugarcane subsider juice, finally again sugarcane subsider juice is sent to evaporation concentration, cane sugar boiling and crystal, the good white sugar of quality can be obtained.The sugar cane juice that this method obtains is because there being a small amount of sulfur to protecting color, the generation of Mei Lade pigment can be suppressed, small molecules pigment can be prevented again in sucrose crystal surface attachment, the sugarcane subsider juice colour produced is low, purity is high, turbidity is low, finally just can obtain the arable land white sugar of the high-quality compared favourably with carbonatation process.
