Abstract
The invention discloses a novel process for cleaning sugar cane juice in sugar production which comprises the steps of, low-temperature phosphor floating treatment, pre-decolorizing with diatomaceous earth and activated charcoal, then loading to boil the sugar. The neutral filtering mud produced in the low-temperature phosphor floating method can be directly used as fertilizer. The process can eliminate the generation of alkaline sieving mud in sugar production.
Description
Technical field
The present invention is a kind of cleaning technique with the cane sugar manufacture sugarcane juice, belongs to the process for cleanly preparing category.
Technical background
China's cane sugar manufacture industry all is to adopt traditional production method for a long time: a kind of is carbonatation process, and another kind is a sulfurous method.The sugar product quality that the carbonatation process production technique is produced is better, but complex process, cost is higher, and the filter mud generation is big.Whenever go into to press 10,000 tons of sugarcanes, produce 800 tons of filter muds.Filter mud is strong basicity, can not be used as fertilizer.Organic content height in the alkaline mud (about 11-13%) can not directly be used for cement baking, and need store up more than 5 years can cement baking, so need build the big area stockyard.In addition, store up and produce secondary pollution in the process.The way of still not having at present cost-effective processing alkaline mud.In order to remove non-sugar and pigment, need to add milk of lime in the carbonatation process production process, carry out carbonation twice, cause the technical process lengthening thus.The investment in sugar refinery 1/3rd is and reaches this purpose.Sulfurous method production process is simpler, invests lessly, and filter mud can be used as farmland fertilizer, so great majority adopt this method.But its quality product is not so good as carbonatation process, product colour, turbidity, ash, sulphur content height, and easy brightness reversion, keeping quality is poor, does not meet market demand day by day.Need for international competition, from 2002/2003 press for extracting juice season, country is with white sugar SO in the target level of product quality of white sugar
2Content is adjusted into 30mg/kg from 40mg/kg, and requires to reduce year by year, plans in white sugar SO in 2005
2Content's index will be reduced to below the 10mg/kg.As seen country is more and more stricter to the sugar product specification of quality, and the quality problems of sulfurous method sugar product directly have influence on its existence.
The present domestic low-temp phosphorus floatation method-carbonatation process clarification process of researching and developing.This technology is carried out low-temp phosphorus floatation earlier and is handled before carbonation, removes most of organic non-sugar.The purity of floating clear juice obviously rises, and colloid and pigment significantly reduce, and have alleviated the burden of clarifying treatment greatly.Carry out carbonation behind the low-temp phosphorus floatation again, the required ash amount that adds significantly reduces.This technology is divided into two kinds to filter mud, and a kind of neutral filter mud that contains fertilizer efficiency such as abundant organic non-sugar and nitrogen phosphorus potassium can directly be used as fertilizer; Another kind contains organic non-sugar seldom, and calcium carbonate content is up to the alkaline mud more than 85%, and directly cement baking or the industry of doing other are used, and owing to add that the ash amount significantly reduces the generation that effectively reduced alkaline mud.But still there is following subject matter in this technology: the direct cement baking of (1) alkaline mud, and cost is higher, is difficult to be accepted by manufacture of cement producer; (2) employing of low-temp phosphorus floatation method causes the sugar product cost to increase; (3) this technology is long than the conventional carbon acid technological process.
Summary of the invention
The purpose of this invention is to provide the peace and quiet process for cleanly preparing of a kind of cane sugar manufacture sugarcane juice, be that the cane sugar manufacture mixing juice is handled through the low-temp phosphorus floatation method earlier, remove non-sugar and partial pigment, utilize diatomite and gac to make adsorption decolouriser then, further remove the pigment in the floating clear juice, make it to reach the requirement of boiling sugar.This technology does not produce alkaline mud.
The objective of the invention is to be achieved through the following technical solutions:
A kind of cane sugar manufacture sugarcane juice cleaning technique, its technical process is: the cane sugar manufacture mixing juice is handled through the low-temp phosphorus floatation method earlier, removes non-sugar and partial pigment; Adopt diatomite that floating clear juice is decoloured in advance then, the syrup after the pre-decolouring adopts gac further to decolour, and sends to and boils sugar (seeing process flow sheet of the present invention for details).
The characteristics of technical process provided by the invention are:
The peace and quiet novel process of sugarcane juice that adopts low-temp phosphorus floatation method and floating clear juice adsorption bleaching to unite, the alkaline mud of having avoided carbonatation process, low-temp phosphorus floatation method-carbonatation process to be caused has shortened technical process.
Adopt the low-temp phosphorus floatation method to handle the cane milling mixing juice, remove non-sugar, removed partial pigment simultaneously, thereby improved juice purity, reduced its colour.
Adopt diatomite and gac to make adsorption decolouriser, further remove the pigment in the floating clear juice, the syrup after guaranteeing to handle satisfies the requirement of boiling sugar.
In the pre-decolorization of diatomite, diatomite uses behind 800 ℃ of roasting 6h, and its add-on is the 1-3wt.% of sucrose part, and pre-bleaching temperature is 50-75 ℃, and pre-bleaching time is 30-60min.
In the activated carbon decolorizing process, the gac add-on is the 0.6-1.5wt.% of sucrose part, and bleaching temperature is 50-85 ℃, and bleaching time is 15-90min.
Embodiment
Purity is the mixing juice of 78.19AP, is preheated to 50 ℃, adds the phosphoric acid mixture, with the milk of lime neutralization, charges into fine uniform bubble, and adds flocculation agent, carries out the low-temp phosphorus floatation method and handles.Neutral filter mud after the separation can directly be used as fertilizer or further extract high value added product.Purity of clear juice is brought up to 80.66AP, and colour is reduced to 92.66 ° of st.To float clear juice and be heated to 75 ℃, add diatomite with respect to sucrose part 1.0wt.%, the 60min that decolours in advance, the syrup colour is reduced to 75.23 ° of st.Add the craboraffin with respect to sucrose part 1.0wt.% then, continue decolouring 30min, the syrup colour is reduced to 30.70 ° of st, can satisfy the requirement of boiling sugar.This process does not produce alkaline mud.
