Traditional Baijiu filtration using diatomaceous earth often results in turbid liquor, poor light transmittance, and a risk of secondary precipitation. Shandong Qisheng Membrane Separation Technology Co., Ltd. has developed a dedicated membrane-based clarification system for Baijiu based on proven membrane separation technology. Through precise sieving, the system achieves efficient purification of the liquor, thoroughly resolving issues of re-cloudiness and sedimentation, and helping producers enhance product quality and market competitiveness.

Process Principle
The system utilizes selective membrane sieving to precisely retain solid proteins, pectins, yeast autolysates, and other impurities, ensuring sustained clarity and extended shelf life.

Technical Advantages

Brilliant Clarity, Superior Quality
0.1 μm high-precision filtration completely removes activated carbon and other impurities, delivering a glossy, crystal-clear liquor with significantly improved light transmittance.

Fouling-Resistant, Durable, Easy Maintenance
Crossflow operation combined with backwashable membrane modules effectively prevents clogging, with membrane service life of 2–3 years. Cleaning requires no disassembly, ensuring rapid flux recovery.

Flexible Adaptation, Easy Retrofit
Compact equipment design with small footprint, supports automatic or manual operation, easy integration into existing production lines and convenient for older plant retrofits.

Energy-Efficient, Stable Operation
No filter aids required, low energy consumption, flexible start-up and shut-down, with consistent and stable filtration performance.
