The overheating preventive continuous culture solution sterilizer comprises a preheating tank which is connected with a heating tower through a pipeline; the heating tower is connected with a maintaining tank through a pipeline; the maintaining tank is connected with a cooling tank through a pipeline; a discharging control tank is connected with the maintaining tank and the cooling tank; the upper part of one side of the discharging control tank is connected with the maintaining tank through a pipeline, and the bottom of the other side of the discharging control tank is connected with the cooling tank through a pipeline; the upper part of the discharging control tank is connected with an air pump through a pipeline; a one-way discharging valve is arranged on the pipeline for connecting the discharging control tank and the maintaining tank; a one-way feeding valve is arranged on the pipeline for connecting the discharging control tank and the cooling tank. The overheating preventive continuous culture solution sterilizer is used for continuously sterilizing a culture solution.
Description
Technical field:
The utility model relates to a kind of anti-overheated nutrient solution continuous sterilizer.
Background technology:
In the process of microorganism culturing, as unsterilised, can make matrix or the product of biological respinse, because of the consumption of miscellaneous bacteria, lose, cause the decline of throughput; Miscellaneous bacteria also can produce meta-bolites, and this just makes the extraction of product more difficult, causes yield to reduce, and quality product declines; Some miscellaneous bacteria meeting degradation production, makes to produce unsuccessfully; After miscellaneous bacteria amount reproduction, can change the pH value of reaction solution, make abnormal reaction; If generation Pollution of Phage, produces mycetocyte by cleaved, make to produce unsuccessfully.
The sterilizing of nutrient solution generally adopts wet-heating sterilizing, and while using moist heat sterilization method to medium sterilization, the temperature and time of heating all has effect to the destruction of microbial death and nutritive ingredient.Because the destruction of medium nutrient content and thalline death all belong to first order kinetics reaction, all available Arrhenius equation of the relation of its reaction velocity constant and temperature represents; Formula is derived thus, and when sterilising temp rises, microorganism kills the raising of speed will be over the increase of the destruction speed of medium component.So adopt high temperature quick sterilization method, can reach the whole lived organism killing in substratum, the destruction that can reduce again nutritive ingredient.If there is superheating phenomenon in sterilization process, the destruction that causes medium nutrient content, current wet-heating continuous sterilisation equipment is complicated, and sterilization process is not easy to control, and often causes the overheated or halfway phenomenon of sterilizing to occur.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of anti-overheated nutrient solution continuous sterilizer, and sterilization process is easily controlled, and has effectively avoided the generation of substratum superheating phenomenon.
Above-mentioned object realizes by following technical scheme:
Anti-overheated nutrient solution continuous sterilizer, comprise preheating can, described preheating can connects heating tower by pipeline, described heating tower is connected and is maintained tank by pipeline, the described tank that maintains connects cooling tank by pipeline, described maintaining is connected discharging between tank and described cooling tank and controls tank, the upper lateral part that tank is controlled in described discharging connects the described tank that maintains by pipeline, the opposite side bottom that tank is controlled in described discharging connects described cooling tank by pipeline, the top that tank is controlled in described discharging connects off-gas pump by pipeline, what tank was controlled in described discharging installs unidirectional discharging valve with described maintaining on tank connected pipeline, on described discharging control tank and described cooling tank connected pipeline, unidirectional feed valve is installed.
Described anti-overheated nutrient solution continuous sterilizer, described heating tower connects steam supply device, and described heating tower the inside arranges whipping appts and temperature sensor.
Described anti-overheated nutrient solution continuous sterilizer, has thermal insulation layer in the described tank body that maintains tank.
Beneficial effect:
1. the utility model is connected discharging between tank and described cooling tank and controls tank maintaining, the upper lateral part that tank is controlled in described discharging connects the described tank that maintains by pipeline, the opposite side bottom that tank is controlled in described discharging connects described cooling tank by pipeline, the top that tank is controlled in described discharging connects off-gas pump by pipeline, like this when off-gas pump is bled work, discharging is controlled tank in negative pressure state, the nutrient solution maintaining in tank enters in discharging control tank by pipeline, and under the effect of gravity, drop to the bottom that tank is controlled in discharging, and cooling tank and discharging are controlled between tank owing to being subject to the restriction of unidirectional feed valve, material in cooling tank cannot enter discharging and control tank, because the connecting tube between cooling tank and discharging control tank is arranged on the bottom that tank is controlled in discharging, nutrient solution enters cooling tank under action of gravity, off-gas pump non-stop run, the nutrient solution maintaining in tank enters discharging control tank, the nutrient solution that discharging is controlled in tank enters cooling tank, like this, as long as control the working order of off-gas pump, just can control easily the time that nutrient solution stops in maintaining tank, effectively avoided the destruction of the overheated medium nutrient content causing of nutrient solution, workable, it is convenient to control.
2. heating tower of the present utility model the inside is provided with whipping appts, and limit is carried out heating edge and stirred, and nutrient solution is heated more even, and set temperature sensor, is convenient to the convenient temperature of grasping heating.
3. of the present utility model maintaining in tank arranges thermal insulation layer, guarantees that nutrient solution sterilising temp is within rational scope, thereby avoids the calorific loss that thermal conduction causes to cause the halfway phenomenon of sterilizing.
