Agitation system

GJ /GJG/GJGG  :machine: Top mechanical agitation , infinite speed variation; rpm 70~1000rpm±1%,The height of the stirring oar can be adjusted,

GC：

Magnetic Drive from bottom, without mechanical seal
The agitation system hanged up is driven by magnetic force. There is no thimble at the bottom. The rotate speed is steady. High-powered stirrer, antifoam stirrer, AC buncher, variable speed control. All parts in the cylinder are set on the cover, so it is convenient to maintain and clean. Standard six- bladed paddle used in fermentation process can be adjusted in the height. The stirrer which has many other styles can be used to meet the special requirement of fermentation process. There is no possibility to leak out the bacteria without mechanical sealing. AC buncher, actiyator. The design which separates the motor from the cylinder makes the weight of cylinder cut down, so it is convenient to operate and save a large amount of manpower. The magnetic force system uses special permanent magnetic material. The special process makes the magnetism permanent. The highest rev will never be less than 980 rpm during the service life of the cylinder. It can meet the highest rev even in the full bodied medium.

Temperature control

Interlayer electric calefaction, auto-control

Airflow control

Manual control,  Flow meter  display 

Each fermenter unit must have provision for working with three gases, namely, air,

O2 and N2 (as necessary), through mass flow controllers. They must be tuned for

low flow rates, e.g., air between 0–1 L/min, O2 between 0–250 mL/min, N2 between

0–500 mL/min. The range for various gases must be specified

Antifoam control

Automatically check foam, automatically add antifoam by peristaltic pump.

Feeding control

Control by peristaltic pump switch, automatically feeding and computation.

pH control

Automatically add acid, alkali by peristaltic pump and control pH accurately.

DO control

Control with rotating speed relatively.

BLBIO-B Biology process controller

Control parameter: temp, pH, DO, antifoam, stirrer rev, feeding; (Other parameters like glucose, amino acid, ethanol, oxygen, carbon dioxide, electric balance system can be chosen to use.)
