AIF air lift type internal circulation fermentation tank, by diverting tube and gas injector ferment gas-liquid two-phase mixture flow in the fermentation tank
Form the overall circulation.Guide tube, gas injector, geometric structure of tank can design according to the characters of fermented liquid properties and microbial metabolism, to meet the relevant microbial growth and product formation of mass transfer, mixing, heat transfer, etc.It is a kind of typical energy-saving fermentation tank.Replace the traditional mechanical mixing ventilation for some products fermentor production, often can save power consumption, reduce maintenance costs, reduce the fermentation workshop noise effect.
Working principle:
Air through a new type of gas injector in lift pipe form gas-liquid mixing jet, strengthen lift mixing and mass transfer in the tube, and caused heavy lifting liquid pipe flow is poor, driving fluid within the whole circulation.
Product features:
(1) air mixing, weak shear damage, low energy consumption, low noise, high loading coefficient, low maintenance cost (requires little maintenance), no moving parts, no mechanical seal, resistance to bacterial contamination.(2) high ratio and nozzle number, mass transfer within the circulation form of hybrid reinforced region according to user's product process requirement and computer CFD results for design.
Areas of application:
AIF gas lift type inner circulation fermentation tank belongs to the energy-saving products, can replace industrial production in China are using generic type mechanical stirring fermenter used lot of fermentation products.Our company provides AIF gas lift type inner circulation fermentation tank series products, is now the biggest volume of 350 m3, single pot for vitamin C fermentation production.Vc is developing 600 m3 for gas lift type internal circulation fermentation tank.
Industrial applications:
Bacterial fermentation (vitamin C, bacterial cellulose);Yeast fermentation (baker's yeast, feed yeast);Fungal fermentation (itaconic acid);Actinomyces fermentation 25 (avi).
