Proses Pembuatan Susu UHT di Pabrik susu Ultrajaya

Introduction

This tutorial outlines the process of manufacturing UHT (Ultra High Temperature) milk at the Ultrajaya dairy factory. UHT milk is a popular choice due to its long shelf life and convenience. Understanding this process can provide insights into dairy production and food technology.

Step 1: Raw Milk Collection

• Source Quality Milk: Gather fresh milk from certified dairy farms. Ensure that the milk meets safety and quality standards.
• Transport: Use refrigerated trucks to transport the milk to the processing facility to maintain its freshness.

Step 2: Milk Reception and Testing

• Receive Milk: Upon arrival, check the temperature and quality of the milk.
• Conduct Tests: Perform tests for fat content, protein levels, and bacterial counts to ensure the milk is safe for processing.

Step 3: Pasteurization

• Heat Treatment: Pasteurize the milk using high temperature for a short time (HTST) method:
  • Heat the milk to at least 72°C (161°F) for 15 seconds.
• Cooling: Rapidly cool the milk to below 4°C (39°F) after pasteurization to prevent bacterial growth.

Step 4: UHT Treatment

• Ultra High Temperature Processing: Use an UHT system to heat the milk to temperatures of 135°C (275°F) for 2 to 5 seconds.
• Aseptic Cooling: Cool the milk immediately after UHT treatment to prevent spoilage while maintaining sterility.

Step 5: Packaging

• Aseptic Packaging: Fill the UHT milk into pre-sterilized cartons or containers in a sterile environment to avoid contamination.
• Sealing: Ensure packages are sealed tightly to maintain freshness and shelf life.

Step 6: Storage and Distribution

• Store UHT Milk: Keep the packaged milk in a cool, dry warehouse away from direct sunlight.
• Distribution: Transport the UHT milk to retailers or consumers, ensuring it remains at a stable temperature.

Conclusion

The production of UHT milk involves several critical steps from collection to packaging to ensure safety and quality. Understanding this process not only highlights the importance of hygiene and technology in food production but also the logistics involved in delivering long-lasting dairy products to consumers.
