AI Technical Summary
Existing plant cell culture devices suffer from low ventilation efficiency, uneven ventilation, easy clogging, and excessive shear force, leading to insufficient oxygen delivery, local hypoxia, cell damage, and production instability.
It adopts a porous panel and bubble baffle design, with the air outlets distributed in a concentric gradient. Combined with an annular baffle and an air inlet column, it forms a multi-stage gas-liquid mixing chamber. Through hydrophilic treatment and gradient pore size design, it optimizes gas dispersion and release, reduces the risk of blockage, and lowers shear force.
It significantly improves oxygen dissolution efficiency, optimizes the stability of the culture environment, reduces cell sedimentation, protects cell viability, and improves batch consistency and cell suspension rate.
