Yogurt Fermentation Process Overview
This controlled process helps ensure uniform texture, clean flavor, and probiotic stability.
1. Milk Preparation
- Pasteurized milk is transferred into the yogurt fermentation tank.
2. Starter Culture Addition
- Yogurt starter cultures are inoculated into the milk.
3. Heating Stage
- The tank maintains the optimal fermentation temperature for controlled bacterial growth.
4. Controlled Fermentation
- Yogurt thickens while acidity gradually develops under controlled conditions.
5. Cooling Stage
- Fermentation stops when the target pH and product texture are reached.
6. Transfer or Packaging
- The yogurt is transferred for further processing, filling, or packaging.
Optional Automation and Smart Monitoring
The Yogurt Fermentation Tank can be configured with different levels of control depending on production scale and quality standardization needs.
Basic Manual Monitoring
Suitable for smaller yogurt startups and pilot production.
Digital Monitoring
Supports:
temperature observation
pH tracking
stronger process supervision
PLC Automatic Control
Supports:
more repeatable fermentation cycles
stronger batch consistency
easier process management
reduced labor dependency in larger plants
Manufacturing and Quality Control
Each ZPET yogurt fermentation tank is manufactured under strict quality standards, including:
Precision welding and polishing
Temperature uniformity testing
Agitator performance inspection
Final hygiene and visual inspection
This helps ensure reliable operation, long-term durability, and stable fermentation performance.
