UHT milk: The milk processed by UHT production line can be stored for a long time without deterioration, and the milk quality is stable without refrigeration. It can be used with aseptic filling machine.
Production line introduction:
UHT milk processing equipment includes UHT sterilizer, high pressure homogenizer, milk refrigeration tank, finished product tank, etc. The milk can reach aseptic state after being processed by UHT equipment, and the shelf life is up to 6 months with secondary filling and sterilization. It solves the problem that milk can not be preserved for a long time. UHT tubular sterilizer and high-pressure homogenizer can ensure the long shelf life of milk and the taste quality of milk. Moreover, it can be connected with aseptic packaging machine seamlessly. Our UHT unit PLC automatic control, and high heat recovery, less energy consumption, CIP cleaning, sterilization temperature accurate and reliable, steam flow, cooling water flow, material flow are strictly controlled, all accessories can use the world famous imported brands, to ensure the highest use quality of the equipment.
Output: 200-10000l / h
Final product packaging: aseptic brick carton, pillow type packing bag etc.
Adapts to multiple end products: whole milk, skimmed milk, flavored milk, plant-based beverages
Key Stages in a UHT Milk Line:
Raw Milk Reception & Storage: Receiving, testing, and storing raw milk or dissolving milk powder.
Pre-Treatment: Filtration, clarification, and fat standardization (separation/recombination) to ensure consistent fat content.
Homogenization: Breaking down fat globules for a uniform texture and preventing separation.
UHT Sterilization: The core step, using either:
Indirect Heating: Plate or tubular heat exchangers (e.g., Tetra Pak DE unit).
Direct Heating: Steam injection or infusion into the milk.
Aseptic Cooling: Rapidly cooling the sterilized milk in a vacuum chamber.
Aseptic Filling & Packaging: Filling the sterile milk into pre-sterilized, airtight cartons (like Tetra Paks) or pouches in a sterile environment.
Ancillary Systems: Water treatment, steam generation, compressed air, and Clean-In-Place (CIP) for automated cleaning.
Types of UHT Systems:
Indirect: Heat transferred through walls (plate/tubular exchangers).
Direct: Milk directly contacts steam (injection/infusion).
OneStep Technology: Newer systems reduce steps, saving costs and energy.
Key Benefits:
Extended Shelf Life: Months without refrigeration.
Nutrient Retention: Preserves flavor and nutrients better than traditional pasteurization.
Operational Efficiency: High volumes, low energy/water use in advanced lines.
