Description
Technical field
The invention belongs to sugar refining field, be specifically related to a kind of production technique and device of yellow gold sugar.
Background technology
Yellow gold sugar, is also brown sugar, gold sand sugar, be contain certain nutritive ingredient be not with sweet granulated sugar.It is faint yellow that color and luster is.Its production technique and white sugar are similar, but also not exclusively filter in process of production the nutritive substance of the inside, so it has preserved part sugarcane fragrance and nutrition, and have retained a lot of natural mineral matters.
Along with improving constantly of Chinese people people production level, people are to the consumption of sugar also diversification day by day.In recent years, also increasing year by year in the eating requirements of the ground brown sugars such as northern China.Therefore,, in the Guangxi, main Chan Tang district of China, there is the middle-size and small-size sugar refinery of part squeezing the initial stage of producing in season or entirely squeezing season and produce brown sugar.For the higher initial stage in squeezing season of reducing sugar, the sugar yield of producing brown sugar is relatively high, both can obtain good economic benefit, can satisfy the demands of consumers again.But it is mainly the production with reference to raw sugar that brown sugar is produced cleaning technique, taking lime method as main, production process sulfurous gas bleaching, contains sulphur residual in product.Must on the basis of lime method, improve, just can make equipment can adapt to production brown sugar, the natural flavor that the while also can retained product sugar.
The technique of domestic production yellow gold sugar is mainly taking lime method as main at present, has introduced new salinity, and in the time of full charge, precipitation, syrup is not clarified, and has not effectively removed the material such as mud juice, colloid in syrup.Cause product purity not high, mouthfeel is poor.Also there is more shortcoming in this technique: first, its technique will adopt lime precipitation removal of impurities, after natural sedimentation or filter press, can produce a large amount of residues, and environmental pollution is more serious; Secondly, in the method, using is that lime needs calcining, has consumed larger energy on the one hand and with waste discharge, has also increased an operation section simultaneously, increases production cost; The 3rd, this product, through long high temperature evaporation, produces Maillard reaction, and the pigment in its product is not natural pigment, and human body be there is no to benefit; The 4th, the concentration technology of the method adopts multiple-effect evaporator, and energy consumption is higher, and production cost is high; The 5th, this technique is relatively numerous and diverse, and equipment is many, control complex process, and floor space is large, and capital construction cost is also high.The 6th, this technique does not have the operation section of desalination,
In view of this, still await proposing a kind of production technique of improved yellow gold sugar.
Summary of the invention
The object of the present invention is to provide a kind of production technique and device of yellow gold sugar, directly, taking sugarcane or beet as raw material, continuously produce high-quality gold sugar, the colourimetric number of products obtained therefrom 800～3000, ratio of desalinization is high, yield is high.
A production technique for yellow gold sugar, comprises the following steps:
Step 1, squeezes sugarcane or beet by draining device, obtain sucrose mix juice;
Step 2, is undertaken step 1 gained sucrose mix juice after pre-filtering by coarse filter, then sends into microfiltration membrane and filter, and obtains sucrose mix juice clear liquid;
Step 3, carries out pre-concentration by step 2 gained sucrose mix juice clear liquid, makes the volume of sucrose mix juice clear liquid be concentrated into 30%～40%, obtains pre-concentration liquid;
Step 4, sends step 3 gained pre-concentration liquid into ion exchange resin and carries out desalination, obtains seeing through liquid, and described ion exchange resin refers to the mixed bed of anion-cation exchange resin;
Step 5, sends into vaporizer by step 4 gained through liquid concentrated, obtains sucrose concentrated solution;
Step 6, when step 5 gained sucrose concentrated solution is warming up to supersaturation, adds crystal seed, and natural decrease temperature crystalline is incubated to crystallization completely in Tc, by centrifugal gained crystallization, obtain yellow gold sugar crystal;
Step 7, step 6 gained yellow gold sugar crystal is dry, obtain finished product.
First pass through draining device, sugarcane or beet are squeezed, obtain sucrose mix juice, then sucrose mix juice is carried out to pre-treatment through coarse filter, remove larger bagasse or beet pulp, to be applied to better follow-up membrane sepn operation, coarse filter herein includes but are not limited to: deep bed filter or screen cloth (aperture of screen cloth is preferably 100～200 orders) etc., fully to remove bagasse or beet pulp.The effect of microfiltration membrane is some granule foreigns, the colloid etc. of removing in sucrose mix juice, can improve purity and the quality of product.Pre-concentration is removed a part of impurity in sucrose mix juice clear liquid and pigment, can not only improve product quality, can also extend the life-span of ion exchange resin.Ion exchange resin can be removed in pre-concentration liquid with salinity and partial pigment, further improves purity and the quality of product.
In step 2, microfiltration membrane preferably adopts ceramic microfiltration membrane or the organic microfiltration membrane of tubular type, and in order to make filter effect more excellent, the mean pore size scope of the microfiltration membrane of employing is 50～500nm.If mean pore size is too little, can cause filtration flux too little, and the sucrose of a part of larger particles can be trapped, have influence on yield; If mean pore size is too large, can cause a part of impurity and pigment to see through rete and enter to per-meate side, have influence on the colour of product.On this basis, the film that mean pore size is 200nm is held back some fat, the protein got rid of in sucrose, and this can ensure the life of ion exchange resin, and can prevent that resin from, by macromole impurity absorption, having influence on the decreasing ratio for salt.Filtration temperature exerts an influence for product quality and strainability, although filtration temperature improves viscosity, the raising filtration flux that can reduce filtered liquid, if but filtration temperature is too high, can there is sex change in some materials in sucrose mix juice, have influence on the quality of the finished product, preferably 20～90 DEG C of filtration temperatures, more excellent is 80 DEG C, in the time that filtering, this temperature section can ensure that filtration flux declines slowly, superior product quality simultaneously.If when filter pressure is less than normal, can cause flux low, do not conform to and be suitable for engineering actual demand, if when pressure is excessive, can cause a part of most of impurity to be pressed, see through rete, cause product colour bad, and can produce more serious Pore Blocking, and make it be difficult for being cleaned, preferred filter pressure is 0.1～0.5MPa; Optimum is 0.3MPa, can ensure that filtration flux declines slowly simultaneously.
