Description
Technical Field
The utility model belongs to a fermentation cylinder, specifically speaking especially relates to a fermentation cylinder with stirring defoaming function.
Background
The mechanical stirring type fermentation tank fully mixes air and fermentation liquor by using the action of a mechanical stirrer to promote the dissolution of oxygen so as to ensure that the dissolved oxygen required by the growth, the propagation and the metabolism of microorganisms is supplied. Since oxygen is difficult to dissolve in the fermentation broth, this requires a stirrer which provides a high dispersing capacity. When a fermentation object is obtained using a biochemical reaction and a fermentation process of a microorganism, foam is formed in a fermentation medium due to introduced oxygen, carbon dioxide generated by fermentation of the microorganism, and the like. When foam is excessively generated during fermentation, the fermentation process is adversely affected and the production rate is decreased. It is difficult for the conventional stirring apparatus to satisfy the requirements of the dissolved oxygen rate and the higher and higher energy consumption, and the conventional foam breaker is installed in the shaft of the stirrer inside the fermenter to eliminate surrounding foam by using the centrifugal force generated by the rotation of the shaft, but when the height of the foam is higher than that of the foam breaker, the defoaming capability is remarkably decreased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fermentation cylinder with stirring defoaming function to overcome the agitating unit of fermentation cylinder among the prior art and be difficult to satisfy dissolved oxygen rate and the more and more high requirement of energy consumption and the defect that the foam requirement disappears.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a fermentation cylinder with stirring defoaming function, includes agitator motor, a jar body, (mixing) shaft and stirring paddle leaf, jar body is equipped with hand hole, sight glass, air inlet and discharge gate, agitator motor fixes at a jar body top to its output shaft (mixing) shaft, stirring paddle leaf fixes on the (mixing) shaft, still be equipped with propeller blade and defoamer on the (mixing) shaft, propeller blade sets up on the (mixing) shaft with stirring paddle leaf interval, the defoamer includes the rotor plate, the higher authority of rotor plate is fixed at least four defoaming blades that are equipped with respectively below with.
Further, the defoaming blade is a spiral blade.
Further, the tank body is provided with a jacket, a cooling water outlet and a cooling water inlet, and the cooling water outlet and the cooling water inlet are communicated with the jacket.
Furthermore, a thermometer inserted into the tank body is arranged on the tank body.
Further, the internal portion of jar is connected with the sampling tube.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses agitating unit can realize horizontal and fore-and-aft stirring simultaneously, keeps lower energy consumption on the basis of increasing dissolved oxygen speed, and the better defoaming effect can be realized to the defoamer simultaneously, especially can also keep better defoaming effect when the height of foam highly is higher than the defoamer.
