The Pasteurization, Yogurt, and Ultra-High Temperature (UHT) Sterilizer (Three-in-One) is a multifunctional liquid food sterilization device that integrates pasteurization, yogurt heating and fermentation pretreatment, and ultra-high temperature sterilization. It is widely used in dairy products (milk, yogurt, flavored milk), beverages, and juices. With features of high efficiency, energy saving, and precise temperature control, it is ideal for small and medium-sized dairy processing plants or pilot production lines.
YME’s Pasteurization and UHT Sterilizer is an industrial thermal processing solution designed for milk sterilization and cleaning equipment applications, yogurt processing, beverage production, and overall liquid food hygiene. By integrating pasteurization, yogurt heat treatment, and ultra-high temperature (UHT) sterilization into one flexible system, this equipment enables dairy and beverage manufacturers to maintain reliable food safety compliance, consistent product quality, and efficient production performance.
This system is widely used in milk processing plants, yogurt factories, beverage production lines, and pilot dairy facilities. As part of a complete milk sterilization and cleaning equipment solution, it can be customized to match different product characteristics, production capacities, and international hygiene standards, while ensuring seamless integration with CIP cleaning systems and downstream processing lines.
Main Functions
1. Pasteurization: Heats milk to 72–75°C for 15–20 seconds to effectively eliminate pathogenic bacteria while preserving nutrients and flavor.
2. Yogurt Pretreatment and Fermentation: Heats milk to 85–90°C for 5–10 minutes to denature whey proteins and improve yogurt texture. Includes cooling and constant temperature control for fermentation.
3. Ultra-High Temperature (UHT) Sterilization: Suitable for flavored milk, milk beverages, and juices. Heats to 90–105°C for 10–30 seconds to destroy heat-resistant bacteria while maintaining product quality.
Features
● Three-in-One Design: Integrates pasteurization, yogurt heating, and UHT sterilization in one unit, saving space and cost.
● High-Efficiency Heat Exchange: Uses tubular or plate heat exchangers for uniform heating and low energy consumption.
● Accurate Temperature Control: Equipped with an automatic temperature control system for precise regulation of temperature, flow, and holding time.
● Easy Operation: Touch-screen control allows mode switching between Pasteurization, Yogurt, and UHT modes.
● Energy Saving: Features heat recovery design and supports CIP automatic cleaning systems.
● Hygienic and Compact: Made of food-grade stainless steel (SUS304/316L), meeting dairy hygiene standards.
Working Principle
The product (such as milk) is pumped into the heating system and passes through different sections: preheating, holding, cooling, and outlet. Operators can select different working modes according to the production process: Pasteurization (72–75°C / 15–20s), Yogurt (85–90°C / 5–10min), or UHT (90–105°C / 10–30s).
Applications
● Pasteurized milk production
● Yogurt and fermented milk processing
● Flavored milk and milk beverages
● Juices, tea drinks, and plant-based beverages
● Educational, laboratory, and pilot dairy production lines
