Modern Condensed Milk Manufacturing Explained
The silky-smooth condensed milk on shelves is a crystallization of food technology and precision engineering. Through three core technologies—vacuum concentration, sugar osmosis preservation, and sterile filling—perishable milk is transformed into a shelf-stable delight. At the heart of this miracle lies an efficient and reliable production line.
1.Gentle & Efficient Pre-treatment
Premium raw milk undergoes stringent inspection
Pasteurization (HTST process) precisely inactivates pathogens while preserving flavor and nutrients
Stable temperature control is critical
2.Vacuum Concentration: The Core Process
Gentle water removal (~60%) in low-pressure evaporation systems
Operating temperatures far below boiling point prevent scorching and lock in milkfat aroma
Precision sugar dosing creates a natural preservative environment (high osmotic pressure) for sweetened condensed milk
3.Crystallization Control: Key to Texture
Rapid, precise cooling induces lactose crystallization
Dynamic temperature control and seeding technology ensure ultra-fine crystals (consistently <15μm)
Achieving the velvety texture consumers love—absolutely no graininess
4.Sterile Filling: Ensuring Freshness & Safety
Tinplate cans sterilized via direct-flame treatment
Filling and sealing completed in a controlled environment
Unsweetened condensed milk requires additional sterilization for commercial sterility
Guarantees extended shelf life and product safety
We deeply understand the pain points of small-to-medium dairy processors worldwide: controlled investment, customized solutions, and timely technical support. Vonfo was created for this purpose:
