摘要： A probe-type online biomass detection apparatus capable of being subjected to high-temperature sterilization includes an optical fiber probe (1), a light source and light receiving sensor module (2), and a signal processing module (3). A portion, which is required to touch cytosol, of the apparatus adopts a detachable design scheme, to meet requirements for high-temperature sterilization of the probe (1). In the meantime, with regard to influence of bubbles in a fermentation tank on measurement values, a bubble filtering structure is provided, to reduce flow rate and number of the bubbles in the measurement area; and a measurement signal is filtered and optimized through a software algorithm, so that interference of the bubbles is eliminated finally.
