Main parameters of solid fermentation tank
Date: 2015-12-22Read: 18
Tank system: Rotary horizontal tank. Material SUS316L, with internal and external precision polishing treatment; Design pressure 0.25Mpa, working pressure 0.01-0.07Mpa; Internal heat transfer, large inoculation port; Equipped with an external jacket and specially designed safety ventilation, exhaust, and sampling ports. The loading coefficient is 40% -60%. ）
Mixing system: mechanical mixing, double helix blade; Speed control: 0~rated speed ± 1rpm (German SEW motor and reducer). Adjustable timing for forward and reverse operation, 0-99min adjustable)
Temperature control: (cooling water+5 ℃) -65.0 ℃± 0.2 ℃ (Pt-100 temperature electrode imported from Germany, fuzzy PID intelligent controller).
Humidity control: primary pressure reduction filtration, secondary pre filtration; The sterilization filter adopts imported filter element and steam filter; Humidity control range: 30%~100% (automatically adjusted through the water spray system. It can also be manually replenished with water.
Hydration time: 0-99 minutes or seconds on; Turn off 0-99 minutes or seconds. ）
Ventilation flow rate: 0~1VVM (rotor flowmeter). 0.2 μ m sterile air filter
Tank pressure: 0-0.3Mpa (indicated by pressure gauge, manually adjusted)
In situ inoculation and mixing: In situ pressure difference or flame uniform inoculation, during the biochemical reaction process, the material mixing and crushing system in the tank is used to achieve uniform and stable fermentation.
Disinfection method: External steam, manual control (steam is directly introduced into the culture medium material in the fermentation tank, assisted by a special stirring system to achieve in-situ high-temperature sterilization. Compared with rotary table and plow tank solid biochemical reaction systems, it eliminates a large number of auxiliary equipment such as solid material steaming pots and sterile material conveying systems. Cooling is achieved by combining vacuum and ventilation, while adjusting the moisture content of sterilized materials.)
