In September 2021, we received an inquiry from a Vietnam customer interested in establishing a 600L yogurt processing plant. This case study details how Shuliy Machinery provided a complete automatic yogurt production line solution that transformed the customer’s dairy farming business into a profitable yogurt manufacturing operation.

🎯 Project Overview: 600L automatic yogurt production line | Installed in Ho Chi Minh City, Vietnam | ROI achieved within 14 months | Now supplying 10+ retail locations

Customer Background and Requirements

The Vietnam customer operates a medium-sized dairy farm with approximately 50 dairy cows, producing fresh milk daily. With the expansion of their business and growing demand for value-added dairy products in the local market, they decided to venture into yogurt production. Their specific requirements included:

• Daily production capacity of 500-600 liters of yogurt
• Ability to produce multiple yogurt varieties (plain, flavored, drinking yogurt)
• Semi-automatic operation suitable for their workforce
• Compliance with Vietnamese food safety regulations
• Compact footprint to fit existing facility
• Training and technical support for local operators

600L Yogurt Production Process

The 600L yogurt processing line follows a standardized production workflow designed for efficiency and product consistency:

Step 1: Milk Reception and Cooling

Fresh milk from the customer’s dairy farm is pumped into the 600L cooling tank immediately after milking. The automatic cooling system rapidly reduces milk temperature to 4°C to preserve freshness and prevent bacterial growth. Temperature sensors continuously monitor and maintain optimal storage conditions.

Step 2: Filtration and Pre-processing

Before processing, milk passes through the duplex filter system to remove any impurities, hair, or particulate matter. The filtered milk then transfers to the pre-heating tank where it’s gradually warmed to 45-50°C in preparation for homogenization.

Step 3: Homogenization

The homogenizer processes milk at 25MPa pressure, breaking down fat globules to create a smooth, stable emulsion. This critical step prevents cream separation in the final yogurt product and ensures consistent texture throughout the shelf life.

Step 4: Pasteurization

The plate pasteurizer heats milk to 85°C for 30 minutes using the HTST (High-Temperature Short-Time) method. This eliminates pathogenic bacteria while preserving the nutritional quality and flavor of the milk. The automated temperature control system ensures precise heat treatment every batch.

Step 5: Cooling and Inoculation

After pasteurization, milk is rapidly cooled to 43°C – the optimal temperature for yogurt culture activity. At this stage, the customer adds their selected yogurt starter cultures (typically Lactobacillus bulgaricus and Streptococcus thermophilus) to initiate fermentation.

Step 6: Fermentation

The inoculated milk transfers to the two 300L fermentation tanks. Temperature-controlled at 43°C for 6-8 hours, the milk undergoes fermentation as beneficial bacteria convert lactose to lactic acid. This process creates yogurt’s characteristic tangy flavor and thick texture. The customer monitors pH levels to determine optimal fermentation completion.

Step 7: Cooling and Packaging

Once fermentation reaches the desired pH (typically 4.4-4.6), yogurt is rapidly cooled to 4°C to halt bacterial activity. The semi-automatic cup filling machine then packages yogurt into 100-150ml plastic cups at a rate of 1,200 cups per hour. Filled cups are sealed, labeled with production dates, and transferred to cold storage.
