- the color of the sugar will depend on the amount of sodium metabisulfite that is added in the process, both in the diluted juice and in the raw molasses.
- An average dose is 100 ppm in the diluted juice, juice base and 200 ppm in the raw juice, juice base.
- the operation of the equipment is routed by a different course to the previous one, in some of its aspects: the equipment works with a lower consumption of oil, energy and labor. The yields are higher as is the quality of the product.
- the equipment currently used has a good dose of common elements with the equipment of the immediate past, the contamination, even when some elements are observed to counteract it remains a problem.
- the white sugar obtained with the described methods has a quality of: Ul colors of 220 to 300, sulphites of 8 to 10 ppm, ashes of 0.2 to 0.4%.
- Patents for clarification of cane juices are used as a base using sulfurous acid, but always starting from SO 2 formed by the burning of sulfur. These patents are CN1206082, CN1068145, CN1121113, US4076552, and CU33740.
- this invention manages to obtain white and refined sugar with the aforementioned characteristics cop the following advantages:
- the quantity of chemical products used in the factory are elements susceptible to contaminating and degrading sugar, and to the environment, as well as the raising of costs in the factory that directly affect the profit margin, in the case of: A) elemental sulfur, B) quicklime, C) Phosphoric acid D) organic bleaching agents such as polyamines and polydagmas E) activated carbon and F) High molecular weight polyacrylamide type flocculants, are essential elements for obtaining a better color and quality sugar in its different clarification processes, whether in juice, meladura or molten liquor for refinery, the decrease of these would help significantly in the cost-quality objectives without affecting the environment or the product.
- Sulfur itself appears to have a relatively low cost in the market, however it represents one of the highest costs in the process, where 100 to 300 ppm based juice is normally used throughout the process, incurring expenses of: a) product, transport and special storage b) controls, restrictions or permits with the government or army because it is an explosive precursor element, c) ecological costs for gas emissions to the atmosphere degrading aquifer fields and mantles, the form of add it to the juice, either by sulfitation tower or ejector equipment, they are vacuum and the SO2 bubble carried to the juice is large, leaving only a small portion of the SO2 (less than 30% of the SO2 formed), the rest 70 % goes to the atmosphere as SO2, which when combined with the humidity of the air forms sulfuric acid, d) maintenance, corrective, preventive and repair costs in the sulfitation system, as well as the degradation throughout Ia manufactures inside and out due to the corrosive capacity of sulfuric acid generated by the sulfur, without counting the quality of sugar affected by these problems,
- C) Phosphoric Acid since it is a complement of the juice to be able to make the chemical reaction together with the lime heating and the flocculant, and this is determined by the level of phosphates that it contains in itself the cane, the decrease thereof contributes to reduce the costs of chemicals occupied in the factory.
- Reducing sugars combine with amino compounds and give color formation in the final sugar.
- the average SO2 required by a mill to obtain sulphited white sugar is 300 ppm (grams of SO2 per tonne of ground cane, such as SO2) .
- a mill that grinds 10,000 tons of cane per day requires 3,000 kilos per day of SO2.
- the atmosphere is 2,100 kilos per day.
- more than 55 million tons of cane are milled in the 6-month harvest, which represents 16,500 tons of SO2 required and a contamination of 11,550 tons of SO2 in the months of December to June.
- the new process of purification and disinfection of the juice is used applying food grade sodium metabisulfite, with low content of heavy metals, supplemented or not with monosodium phosphate, added to the cane juice after leaving the mills, having passed through the imbibition and filtration process, having removed the pre-alkalization process and mixing it evenly in the diluted or mixed juice with a minimum retention time of 10 minutes before entering the liming process, characterized by this purification and disinfection process by: A.-The use of sodium metabisulfite supplemented or not with monosodium phosphate under the conditions of the diluted juice, with temperatures from 30 to 4O 0 C, pH from 5.0 to 5.5, Solids from 14 ° to 16 ° Bx and sucrose from 12 to 16% and contact times of 10 to 15 minutes before adding Cal, in order to: a) release SO2 that bleaches the juice, The method of using sodium metabisulfite at this stage of the process avoids Ia formation of color in the juice because the SO2 contained
- the removal of color and turbidity will depend on the precipitates generated by reacting the sodium metabisulfite, supplemented or not with monosodium phosphate, with impurities from the juice, lime and temperature.
- the components of the juice purified and disinfected with said process on the one hand with the Phosphates added to the juice as external sources such as phosphoric acid or others including monosodium phosphate (complement of this product), or phosphates of the juice that is found in higher levels of 150-200 ppm will form tricalcium phosphate that, with the help of the high molecular weight polyacrylamide type flocculant, will trap some donor color and turbidity colloids in the juice and on the other 35% of the sodium metabisulfite formula will react with the calcium of the juice, the lime and the temperature forming calcium sulphite, another precipitate that catches other colloids that with the help of the flocculant eliminate other components of the juice that provide color and turbidity.
- the application dose varies from 50 to 200 ppm (grams of the product for each cubic meter of diluted juice (1000 liters of diluted juice), according to the quality of the clear juice that is desired. To determine the most appropriate dose , a clarification test is performed in the laboratory, as detailed below.
- F.- pass it through a clarifying decanter equipment, where helped with a flocculant of high molecular weight and anionic charge of 30 to 35%, with doses of 5 to 7 ppm (grams per m3 of diluted juice).
- G.- A clear juice is obtained with color reduction Ul (Units lcumsa) of 20% minimum depending on the impurities of the juice and the amount of sodium metabisulfite supplemented or not with monosodium phosphate that is added, observing in transmittance removals of the 40% to 60%, and a turbidity reduction of 40% to 50%, than those obtained with sulfur sulfation. Clearing Clarification Ul (Units lcumsa) of 20% minimum depending on the impurities of the juice and the amount of sodium metabisulfite supplemented or not with monosodium phosphate that is added, observing in transmittance removals of the 40% to 60%, and a turbidity reduction of 40% to 50%, than those obtained with sulfur sulfation. Clearing Clarification
- the meladura is clarified to obtain a better quality of sugar, to reach colors of 150 Ul or less.
- Applying sodium metabisulfite at a rate of 100 to 400 ppm (grams of product per m3 of milling) results in a decrease in color in the order of 1800 to 2500 Ul and turbidity of 60 to 70% with respect to the traditional Clarification process without the sodium metabisulfite obtaining in clarified molasses colors of the order of 8,000 to 9,000 Ul, and turbidity less than 70 NTU, where sugar colors less than 150 Ul and sulphites (SO2) less than 4 ppm can be obtained.

- heat the molten liquor sometimes add an organic bleach and always a low anionic flocculant, clarify by flotation, add activated carbon, filter and follow its crystallization, centrifugation, washing and drying process, for packing or bulk.
- sodium metabisulfite is added just before applying phosphoric acid, a color decrease of 20 to 30% is obtained, to obtain white sugar with colors less than 40 Ul, sulphites less than 5 ppm and smaller ashes of 0.04%.
- the clarified Juice is about adding to the diluted juice of the sugar cane food grade sodium metabisulfite supplemented or not with monosodium phosphate, diluted in water using mechanical stirring at a concentration of 50% by weight and adding it to the diluted juice at the outlet of the mills preparing the solution every 4 hours. It is recommended to automate the dosage of sodium metabisulfite in solution by coupling it to the rotameter of the diluted juice with a frequency variator in the dosing pump.
- the application is made after the filtration of the juice by means of rotary filters or stationary type, to eliminate bagasse.
- the primary juice determines free phosphates, which must be in the range of 250 to 300 ppm, to help purify the juice. Contents of less than 200 ppm of free phosphates must be supplemented with phosphoric acid or monosodium phosphate in the order of 50 to 100 ppm ground cane base. The phosphoric acid or monosodium phosphate must be added in the diluted juice to form tricalcium phosphate with the calcium that the cane juice brings.
- the SO2 formed in this way is used 100% to be formed at the same temperature as the juice and at atmospheric pressures.
- the retention time of sodium metabisulfite before alkalization should be
- the quantity in kilos of the product per hour is calculated. For example, a dose of 100 ppm ground cane base for a mill that grinds 10,000 tons of cane per day, will have a dose of 1000 kilos per day between 24 hours, 41.66 kilos per hour.
- A.- Contains less impurities, greater purity of 1 to 1.5 points, less turbidity of 40 to 50%, better transmittance of 60 to 70%, lower color of 20 to 25%, compared to that obtained with the sulfur burning process elementary.

- the standard sugar under the Mexican standard has a maximum limit of 20 ppm of sulphites (SO2), ashes less than 0.25%. Clarified shaking
- the melting equals approximately 25% of the diluted juice, due to the water lost in the evaporation and is equivalent to 50 ppm of grams of MBS per m3 of diluted juice.
- the clarifying equipment also called "float"
- float forms a sludge cake in the upper part and below it a tinge is generated with less turbidity and color, ensuring a better quality of the sugar obtained.
- the amount of MBS that has to be applied to the process is calculated as follows: Assume as an example an mill that grinds 10,000 MT of cane per day and that the initial dose in the Laboratory tests were 200 ppm (mg of MBS per liter of peeling), juice mixed with 16 ° Bx and peeling of 65 ° Bx.
- the dose in kg / hour is calculated as follows.
- the molasses obtained with the use of sodium metabisulfite is characterized by having: less color and turbidity.
- sodium metabisulfite is used in the melting of the raw or standard sugar, decreasing the color that favors the quality of the sugar obtained and the decrease of the addition of activated carbon.
- the dose for this part of the sugar process is 50 to 100 ppm based molten sugar.
- molten liquor continues its refining process, as follows: 1.- Phosphoric acid of 100 to 200 ppm, molten liquor base is added. At this point, bleaching chemicals such as polyamines, polygamymes, aluminum polychlorides and mixtures thereof are used, which have an effect of precipitating undesirable colloids at a rate of 80 to 120 ppm molten liquor base.
