Abstract
A fermentation tank comprises a tank body with both a feed opening and a discharge opening, a stirrer arranged in the tank body and a motor arranged above the tank body and connected with the stirrer, wherein a water flow jacket is arranged between the outer wall and the inner wall of the tank body; a water inlet is formed in the lower part of the water flow jacket; a water outlet is formed in the upper part of the water flow jacket. Hot water can be pumped to heat up the tank body while cold water can be pumped to cool down the tank body. A temperature sensor is also arranged in the tank body to accurately sense the temperature in the tank body, and the temperature is displayed by a temperature display, so that an operator can accurately control the temperature in the tank body to ensure normal fermentation. Particularly, in case of overhigh temperature, cold water is promptly pumped to reduce the temperature. Besides, owing to specific heat capacity of water, an excellent thermostatic function can be performed.
Description
Technical field
The utility model relates to microbial culture system field, specifically a kind of fermentor tank.
Background technology
Fermentor tank is closed container or the biological reaction apparatus that is mainly used in culturing micro-organisms bacterial classification or cell.Can be used for research, analyze and produce.Existing microbial fermentation engineering requires to increase to fermentor tank, not only requires sanitary condition but also requires temperature control and control oxygen.As number of patent application: 201320427971.5 utility model discloses a kind of fermentor tank, solves existing fermentor tank cost of manufacture high, and fermentation costs is high, the problem that maintenance cost is high.This fermentor tank comprises the tank body with opening for feed and discharge port, be arranged at the agitator in tank body, and the motor that is arranged at tank body top and is connected with agitator, the outside of described tank body be provided with and tank body between form the steam jacket of mezzanine space, and this steam jacket top is provided with water vapour import, and bottom is provided with condensation-water drain; In described tank body, be provided with temperature inductor, and be provided with in tank body outside the temperature indicator being connected with temperature inductor by wire.
The enlarged culturing of bacterial classification, need to consider the various growth conditionss of microbial strains; Comprise temperature, pH value, oxygen, kind age, inoculum size.Wherein temperature, pH value, oxygen all need culture apparatus to regulate.Temperature generally provides by thermostat, but to equipment require highly, industrial production cost is high.The adjusting of oxygen is generally by stirring and the adjusting of ventilating, also relevant with tank body.Culture tank is dark, and mixing speed is large, and bubble residence time in nutrient solution is just long, and the solubleness of oxygen is just large, and the viscosity of substratum is less, and the solubleness of oxygen is larger.But excessive agitation can cause nutrient solution to gush in a large number bubble, increase microbiological contamination probability.The solubleness of oxygen has vital effect to microorganism enlarged culturing.At present guarantor's mild heat power taking of fermentor tank is main, and its shortcoming is that fermentor tank cost of manufacture is high, and fermentation costs is high, and maintenance cost is high, and temperature is difficult to controlledly accurately, cannot meet people's requirement.
Utility model content
The purpose of this utility model is to provide a kind of fermentor tank, solves the problem that current fermentor tank is difficult to control temperature and oxygen.
To achieve these goals, the utility model adopts following technical scheme:
A fermentor tank, comprises the tank body with opening for feed and discharge port; Be arranged at the agitator in tank body, and the motor that is arranged at tank body top and is connected with agitator; Between the outer wall of described tank body and inwall, be provided with current chuck, this current chuck bottom is provided with water-in, and top is provided with water outlet.
Further, be provided with at least 2 group stirring rakes on the stir shaft of described agitator, wherein at least 1 group stirring rake is arranged on the liquid level of fermented nutritive liquid.
Further, on described tank body, be also provided with the cleaning water inlet pipe that cleans tank body; On described cleaning water inlet pipe, be provided with tensimeter.
Further, the bottom of described tank body is also provided with thief hole, and the stopple coupon being connected with thief hole stretches into tank body center.
Further, in described tank body, be provided with temperature inductor, and have in tank body outer setting the temperature indicator being connected with temperature inductor by wire.
Further, described tank body is provided with air intake duct and escape pipe; Described escape pipe is also provided with sterile filtration net.
As preferably, the LED lamp throwing light on can also be set in tank body and can see the spread cultivation photoscope of situation of nutritive medium of inside.
The beneficial effects of the utility model are:
(1) the utility model tank body is provided with current chuck outward, and passing into hot water can heat tank body, passes into cold water and just can carry out cooling to tank body.In tank interior, be provided with temperature inductor, can excessively accurately sense the temperature in tank body, and show by temperature indicator, be always that operator can accurately control the temperature in tank body simultaneously, guarantees to ferment normally to carry out.Especially when excess Temperature, passing in time cold water can lower the temperature.In addition, specific heat of water holds larger, can well play the effect of constant temperature.
(2) on the stir shaft of the agitator described in the utility model tank body, be provided with at least 2 group stirring rakes, wherein at least 1 group stirring rake is arranged on the liquid level of fermented nutritive liquid.After passing into air, when the stirring rake arranging like this stirs fermented nutritive liquid, the stirring rake on the liquid level of top can accelerate flowing of air, also the nutritive medium splashing can be broken up, and these have all accelerated the solubleness of oxygen in fermented nutritive liquid.
(3) bottom of the utility model tank body is also provided with thief hole, and the pipe being connected with thief hole stretches into middle part in tank body.In prior art, thief hole opening is in jar top or bottom, and institute's sample thief, at nutritive medium edge, is unfavorable for showing mean level (ML), and error is larger.And the utility model sampling is nutritive medium center sample, average degree is higher, and error is less.
(4) on tank body described in the utility model, be also provided with the cleaning water inlet pipe that cleans tank body; On described cleaning water inlet pipe, be provided with tensimeter, the cleaning water inlet pipe arranging is in addition exclusively used in tank body and cleans, and reduces microbiological contamination probability.
(5) air outlet described in the utility model goes out to be also provided with sterile filtration net, when to outside exhaust, because the existence of sterile filtration net further reduces microbiological contamination probability.
The utility model, simple in structure, easy to operate, safe and reliable being suitable for applied.
