⚙️ How the Yogurt Production Line Works
An industrial yogurt production line consists of a step-by-step process that ensures hygienic, efficient, and consistent yogurt manufacturing.
✅ Step-by-Step Process:
1️⃣ Milk Reception and Standardization
- Raw milk is received and analyzed.
- Standardized to desired fat/protein levels.
2️⃣ Pasteurization
- Heated to 85–95°C for 15–30 seconds.
- Kills harmful bacteria while retaining nutrients.
3️⃣ Homogenization
- Breaks fat globules for smooth texture.
4️⃣ Cooling and Inoculation
- Milk is cooled to 42–45°C.
- Starter cultures are added.
5️⃣ Fermentation
- Mixture is incubated at 42°C for 4–6 hours.
- pH drops to 4.5, forming yogurt.
6️⃣ Cooling to Stop Fermentation
- Rapidly cooled to 4–8°C to halt microbial activity.
7️⃣ Flavoring and Mixing (Optional)
- Add fruits, sugar, or flavors.
8️⃣ Filling and Packaging
- Yogurt is filled into cups, bottles, or pouches.
- Sealed, labeled, and ready for distribution.
