Unmatched Freshness, Efficiency and Flexibility

APV® Infusion UHT Systems deliver premium-quality aseptic and extended shelf life (ESL) processing with precise heat treatment through direct steam infusion and controlled temperature profiles. Compared to traditional UHT systems, it better preserves taste, texture, and nutrients while ensuring product safety. This patented technology has the ability to rapidly heat products to 157°C in just 0.09 seconds, achieving high bacterial spore kill rates while minimizing thermal degradation.

Using free-falling strings in a precisely controlled chamber, this process:

• Eliminates harmful microorganisms
• Ensures optimal heat penetration
• Preserves nutrients and flavors for a fresh, pasteurized-like taste

Infusion UHT milk has a distinct taste profile, with a fresher, more natural taste than traditional UHT and pasteurized milk. Its high-temperature, short-time process—where milk is rapidly heated and flash-cooled—minimizes thermal damage for superior quality.
