FEATURES DETAILS

Airless vacuum evaporator

The airless evaporator operates under vacuum to remove air and dissolved gases from the product, as well as the oxygen responsible for oxidation. For milk, it acts as a deodorizer, eliminating unwanted aromas. For juices, it incorporates an aroma recovery system that condenses and reintroduces the aromas into the product.

Multiple heating systems

Three technologies are available: direct steam injection heating for high-density products, indirect heat exchanger heating for high energy efficiency, and a combined system for maximum versatility. The UHT-Flexy direct system is specifically designed for whipped cream, pastry cream, and high-density products.

Automation and advanced control

The PLC control system with a touchscreen HMI interface enables precise management of all process parameters. Automatic data logging ensures traceability and compliance with HACCP standards. Remote supervision allows for monitoring and predictive maintenance.

Areas of application

Our UHT sterilizer is suitable for various applications in the food industry:

UHT milk - Can be stored for up to 12 months without refrigeration
UHT creams - Whipped cream, pastry cream, fresh cream
Plant-based drinks - Almond milk, soy milk, oat milk, rice milk
Fruit juices - Pure juices, nectars, smoothies
Culinary preparations - Sauces, soups, dessert mixes

Advantages of UHT treatment

Absolute food safety

The complete elimination of pathogenic microorganisms and spores guarantees maximum food safety. The sterilized product does not require a cold chain, reducing the risk of contamination.

Extended Market

Long-term storage allows access to wider geographical markets without the logistical constraints of refrigeration, opening up new business opportunities.

Preservation of quality

Unlike traditional sterilization methods, UHT technology better preserves the nutritional qualities, color, and original flavor of products while ensuring long shelf life.

Technical Frequently Asked Questions

Expert questions on UHT sterilizers and ultra-high temperature processing technologies

Ultra-high temperature (UHT) processing uses higher temperatures (135-150°C) for a very short time (2-8 seconds) to completely sterilize the product, eliminating all microorganisms and spores. Traditional pasteurization uses lower temperatures (72-85°C) for a longer period, reducing but not completely eliminating the microbial load. UHT milk has a shelf life of several months without refrigeration, unlike pasteurized milk, which only keeps for a few days in the refrigerator.

Direct heating via steam injection allows for extremely rapid heating (a few seconds) with minimal thermal impact on the product, thus better preserving its organoleptic qualities. It is particularly well-suited to sensitive products such as creams and high-density preparations. Indirect heating via a heat exchanger offers greater energy efficiency and is ideal for standard products like milk. Our UHT-Flexy system combines the advantages of both technologies to meet the specific needs of the product.

The airless evaporator operates under vacuum conditions to remove air and dissolved gases from the product, particularly oxygen, which is responsible for oxidation. For milk, it acts as a deodorizer by eliminating unwanted volatile compounds. For juices, it incorporates an aroma recovery system that condenses and reintroduces natural flavors into the product. This technology significantly extends shelf life and improves the stability of the final product.

Our UHT system guarantees complete elimination of all pathogenic microorganisms and their spores, with a reduction of more than 12 log (99.9999999999%) of bacteria. This efficacy is validated by microbiological tests conforming to international standards. The system maintains a temperature accuracy of ±0.5°C and a controlled holding time with a maximum deviation of ±0.2 seconds, ensuring perfect sterilization with every cycle.

Our optimized UHT technology combines ultra-fast heating and immediate cooling to minimize the thermal impact on nutritional components. The preservation of heat-sensitive vitamins (including B1, B6, B12, and C) is maximized thanks to extremely short processing times. Milk proteins undergo minimal denaturation, preserving their biological value. Comparative studies show a retention of over 90% of the original vitamins, compared to 50-70% in traditional processes.

Our UHT sterilizer is extremely versatile and can process a wide range of liquid products: whole, skimmed, and standardized milk; all types of cream (whipped, pastry, fresh); plant-based drinks (soy, almond, oat, rice); pure fruit juices and nectars; smoothies; liquid soups and sauces; dessert mixes; and even some high-viscosity products thanks to our specialized UHT-Flexy system. Each configuration is optimized for the specific product with customized processing parameters.
