Total volume: 350L 250L
D:H : 1: 1； Working volume：70%-75%
Vessel：The main material is stainless steel 316L , the inner surface of the tank is polished Ra≤0.2um, the jacket is 304, and the insulation layer is 304.
Sandblasting/drawing matt treatment Ra≤0.8um for external surface. No dead angle in tank; Adopt large viewing angle observation sight glass for liquid level in the tank, top sight glass, two strip sight glasses at side, 12V safety sight light, with temperature, Liquid level interface, inoculation port, refilling port, CIP cleaning port and multiple spare ports, all welds are firm and neat and beautiful.
Vessel design pressure: 0.35Mpa
Jacket design pressure: 0.35 Mpa,
The optimized diversion design improves the exchange efficiency and the uniformity of the temperature in the tank, because stable and uniform temperature control is the basic condition for successful fermentation.
Motor: Frequency conversion drive, adopts German SEW frequency conversion motor. The separate design of the motor and the tank body greatly reduces the weight of the tank body, makes the operation easier and more convenient, and saves a lot of manpower.
Filter: It adopts the secondary filter of sterilization with the accuracy of 0.2μm 99.99% of Sartorius, automatic sterilization and automatic drying.
Tank pressure: Adopt pressure sensor (German Bode) for automatic tank pressure control and adjustment, digital display by pressure electrode.
Stirring form: 2 to 5 level 3 propellers, blade height is adjustable and the blade quantity can be increased or decreased
Temperature control: automatic heating and water cooling, Danish Grundfos circulating pump for temperature control, with air self-escape function and water cut-off, over-temperature protection function, with good heat exchange efficiency; intelligent module control ensures rapid temperature control. Energy saving has also been achieved.
Sterilization : in situ automatic sterilization；
