Abstract
The invention discloses a glucose crystallizer and a production technology. The crystallizer comprises a crystallizing tank, wherein a feed port and a discharge port are formed on the crystallizing tank, the crystallizing tank further comprises a sterile air input part, the sterile air input part comprises a sterile air pipeline, and compressed air which is filtered through a sterile air filter enters the crystallizing tank through the sterile air pipeline. The glucose crystallizer has the beneficial effects that in order to realize a purpose of lowering the contamination rate, the glucose crystallizer is additionally provided with the sterile air input part, thus, the inside of the crystallizing tank is kept in a positive pressure state all the time, the cross infection of the inner environment of the tank and the outside environment is effectively avoided, and outside air, dust and the like can be prevented from entering the crystallizing tank to cause material contamination. The glucose crystallizer has the advantages of simplicity in structure, low equipment investment, good use effect and simplicity in technology.
Description
Technical field
The present invention relates to glucose production technical field, especially relate to a kind of technique that can effectively reduce the production unit of microbiological contamination rate in glucose crystallization process and apply this device fabrication glucose.
Background technology
Glucose is the indispensable carbohydrate of the mankind, is the main source of necessary for human energy, is the important supplementary material of medicine, food and related industries.The horizontal crystallizer of the more employing of the domestic crystallization processes for the production of glucose at present, due to the required material dry of glucose crystallization relatively low (68-72%), and Tc is lower, and (wherein the full material temperature degree of crystallizer is 45 ℃ of left and right, blowing temperature is 28 ℃ of left and right), therefore adopt this kind of crystallizer for the production of glucose, be easier to microbiological contamination.
On horizontal crystallizer, directly use water coolant to lower the temperature, making to evaporate rear saccharified liquid lowers the temperature according to standard temperature lowering curve, thereby orderly crystallize out, obtains the massecuite that yield is higher, but because this process duration is grown (12-189 hour), material temperature of charge in crystallizer is on the low side simultaneously, cause bacterium to be easier to grow, thereby crystallizer microbiological contamination occurs, cause the raising of production cost and the increasing of staff labor intensity.
Summary of the invention
The object of the invention is to overcome the shortcoming existing in prior art, a kind of production technique that can reduce the crystallizer of microbiological contamination rate in glucose production and use this crystallizer is provided, this crystallizer by carrying aseptic compressed air continuously in crystallizer, remain barotropic state in crystallizer, thereby effectively prevent the cross-contact of the interior environment of tank and external environment, reach the object that reduces microbiological contamination rate, the technical scheme adopting is: a kind of glucose crystallization machine, comprise crystallizer, on crystallizer, be provided with opening for feed and discharge port, it is characterized in that: described crystallizer also comprises sterile air importation, described sterile air importation comprises sterile air pipeline, pressurized air after aseptic air filter filters is passed in crystallizer by sterile air pipeline.
Technical characterictic of the present invention also has: described sterile air importation also comprises pressure limiting valve, and the pressurized air after described aseptic air filter filters enters into crystallizer through sterile air pipeline after pressure limiting valve pressure limiting.
Technical scheme of the present invention also has: a kind of right to use requires the glucose crystallization production technique of glucose crystallization machine described in 2, it is characterized in that: this technique comprises following production stage:
1) before charging, open sterile air importation, by the pressure limiting of pressure limiting valve, make maintenance barotropic state in crystallizer;
2) in crystallizer, starch by opening for feed input glucose, this syrup temp is 43-48 ℃, dry 68-72%;
3), after glucose syrup is full of crystallizer, in crystallizer, inject crystal seed;
4) lower the temperature according to temperature lowering curve by water coolant;
5) blowing after temperature of charge is reduced to 27-30 ℃.
Technical characterictic of the present invention also has: described malleation refers to that crystallizer internal pressure is more than or equal to 0.5mbar.
Beneficial effect of the present invention is: in order to reach the object that reduces microbiological contamination rate, this equipment has increased sterile air importation, thereby remain barotropic state in crystallizer, effectively prevent the cross infection of environment and external environment in tank, the material microbiological contamination of having avoided outside air, the dust etc. to enter causing in crystallizer.The advantage that the present invention has is simple in structure, facility investment is few, result of use good, technique is simple.
