10T (10HL) Yeast Propagation System Brewery Yeast Pitching Stock Tank
Automatic Two-Stage Yeast Culture Expansion Tank with Siemens PLC, ABB & Schneider
This 10-Tonne Yeast Propagation System is a fully automated, aseptic yeast culture line designed for medium-to-large breweries to produce high-vitality, contaminant-free pitching yeast in-house. The process begins with media (wort/nutrient) being heated to 100°C for sterilization, flash-cooled to 30–40°C, then gently agitated under sterile conditions for 24h (Stage 1).
Nutrient is replenished and temperature held at 28–30°C for another 24h (Stage 2) before the active yeast culture is transferred to the 10T Yeast Storage Tank ready for pitching into fermenters. The system includes steam boiler (or electric heating), refrigeration unit, air compressor, sterile air filter, hot & cold water tanks, and a PLC cabinet with remote-access control.

Usage Scenarios
Commercial Breweries (10,000L+ batch size) – Generate sufficient healthy yeast in-house to avoid repitching beyond safe generations.
Multi-Strain / Seasonal Brewing Programs – Isolate and propagate distinct ale/lager strains under aseptic conditions.
Bio-Pharma & Enzyme Culture Pilot Plants – Applicable to any aerobic microbial culture requiring sterile aeration & temp control.
Breweries Seeking Consistency – Standardize yeast cell count & viability → reduce fermentation lag & off-flavors.
Turnkey Expansion Projects – Integrates with existing brewhouse CIP, BBT & fermentation lines.

frequently asked questions
1
Q: What is the typical yeast propagation cycle in this system?
A: Media sterilized at 100°C, cooled to 30–40°C, cultured 24h, nutrient added, held 28–30°C another 24h, then transferred to 10T storage.
2
Q: Does the system include sterile air filtration?
A: Yes, 0.22μm membrane sterile air filter with steam-sterilizable housing is standard.
3
Q: Can I monitor the yeast propagation process remotely?
A: Yes, the Siemens PLC supports Ethernet/4G remote access for real-time monitoring and recipe management.
