UHT Systems

Advanced UHT and ESL Processing for Product Quality, Efficiency and Flexibility

APV Infusion UHT System

Every ESL or UHT product places different demands on a UHT system. A premium milk, an oat beverage and a high-protein nutritional drink may all require extended shelf life, but the processing approach needed to achieve the desired quality, operational efficiency and production performance can vary significantly.

Today's producers seek to reduce energy consumption, improve sustainability, extend production runs and bring new products to market faster. At the same time, consumers expect high-quality products with appealing taste, texture and nutritional value. Balancing these requirements requires more than simply applying heat. It requires selecting the right processing technology for the product, the process and the business objectives.

The APV portfolio combines direct and indirect UHT technologies that help manufacturers address a broad range of processing challenges. Whether the priority is premium product quality, production flexibility, operational efficiency or long-term sustainability, producers can choose solutions designed around their specific requirements rather than a one-size-fits-all approach.

Selecting the Right APV UHT System

Choosing the right APV UHT system is essential to achieving the desired product quality, operational efficiency and total cost of ownership. While some applications have a clear solution, others require careful evaluation of product characteristics and processing requirements.

Key factors to consider include:

  • Product formulation and quality requirements
  • Viscosity and presence of particulates or fibers
  • Heat sensitivity and stability
  • Acidity (high- or low-acid products)
  • Required flexibility and production capacity
  • Preference for direct or indirect heating
  • Operator skill level and plant capabilities

UHT systems are often designed to process multiple products, making flexibility and scalability important considerations when selecting the right solution.

Compare APV UHT Technologies

The table below compares the primary APV UHT technologies and highlights the applications where each technology delivers the greatest value.

Choosing the Best Technology

The following recommendations provide a useful starting point when selecting an APV UHT system.

  • Choose Plate UHT for cost-effective processing of low-viscosity products with high energy efficiency.
  • Choose Tubular UHT for reliable processing of viscous, fibrous or particulate products.
  • Choose SSHE UHT for highly viscous, shear-sensitive or particulate products that require continuous scraping to reduce fouling and maintain consistent performance.
  • Choose Injection UHT when you need an effective balance of product quality, flexibility and processing performance.
  • Choose Infusion UHT when preserving product quality and minimizing thermal impact are the highest priorities.

For more complex applications, APV works closely with producers to evaluate product characteristics, production objectives and processing requirements. Through our global Innovation Centers, customers can test formulations, validate processing conditions and compare different UHT technologies before investing in a production system. This helps ensure the selected solution delivers the desired product characteristics, operational performance and long-term value.

UHT Technology Suitability by Application

Every application has different processing requirements. The tables below provide general guidance for selecting the most appropriate APV UHT technology.

Insight

Direct Infusion UHT is often the preferred choice for premium dairy, plant-based and nutritional beverages because it minimizes thermal impact while helping preserve taste, color, nutritional value and overall product quality. However, the optimal solution always depends on product formulation and processing requirements.

Rating Guide

Note
These ratings provide general guidance based on typical applications. The optimal UHT technology depends on product formulation, viscosity, particle size, fouling tendency, required shelf life, production capacity and quality objectives. Product trials in an APV Innovation Center are recommended for complex applications.

Frequently Asked Questions

The right choice depends on product sensitivity, viscosity and desired quality. Infusion systems are ideal for high-value dairy, plant-based and nutritional beverages where gentle processing is critical. Injection systems offer a balance of quality and efficiency, while tubular systems provide robust performance for viscous or particulate products.

Fouling is a common challenge, especially for high-protein dairy, plant-based and nutritional products. Advanced system design, optimized flow dynamics and innovations such as seamless infusion vessels help reduce product buildup, enabling longer production runs, improved uptime and lower cleaning costs.

Maintaining taste, texture and nutritional value is critical, particularly for sensitive dairy and plant-based formulations. Gentle heating technologies, such as infusion UHT, minimize thermal impact and help preserve product integrity while still achieving required shelf life and food safety standards.

Energy consumption is a key concern for all producers. Heat recovery systems and technologies like SteamRecycle™ significantly reduce energy usage by reusing process steam, lowering operating costs and supporting sustainability and decarbonization goals.

UHT systems are designed to integrate seamlessly with aseptic tanks and filling equipment, ensuring sterility is maintained throughout the process. This is essential for achieving extended shelf life and consistent product quality across dairy, plant-based and nutritional applications.

Products such as oat, almond and high-protein beverages can be sensitive to heat and prone to fouling or instability. Selecting the right UHT technology, combined with process optimization and testing in Innovation Centers, helps ensure stable, high-quality results.

Modular system design, automation upgrades and process optimization allow producers to increase capacity and adapt to new products without full system replacement, reducing capital investment while improving performance.
