Introduction
DSI Direct UHT units are advanced heat treatment systems designed specifically for the food and beverage industry. DSI Direct UHT unit’s primary function is to sterilize liquid products quickly and efficiently, ensuring safety by destroying harmful microorganisms while maintaining the nutritional value, taste and color of the product. This DSI Direct UHT unit is typically used for liquids such as milk, juices, beverages, soups and sauces.
>> Feature
Direct Heating Technology: DSI Direct UHT units utilize direct steam injection to heat liquids. Steam is injected directly into the product, rapidly raising its temperature to the desired sterilization level. This method is faster than indirect heating (such as using a plate heat exchanger) and allows for better energy efficiency and faster processing times.
Highly efficient sterilization: This DSI Direct UHT unit heats liquids to ultra-high temperatures (usually between 135°C and 150°C) in a very short period of time, effectively killing bacteria, yeast, mold and other pathogens. This rapid heating minimizes the time the product is exposed to heat, preserving its sensory qualities and nutritional content.
Energy Efficient Design: DSI Direct UHT units are designed with energy efficiency in mind. It features optimized steam utilization and an advanced heat recovery system that captures and reuses thermal energy to preheat incoming products, reducing overall energy consumption and improving operational efficiency.
Precise Temperature Control: The DSI Direct UHT unit includes an advanced temperature control mechanism that precisely adjusts temperature and processing time, ensuring each batch is processed to precise quality and safety standards.
Automated operation: UHT units are fully automated and can be easily integrated into production lines. The DSI Direct UHT unit includes a PLC (Programmable Logic Controller) with a touch screen interface, providing users with real-time monitoring and control of the sterilization process. This automation reduces the need for manual intervention, minimizing human error and improving operational efficiency.
Premium Materials: The DSI Direct UHT unit is made of stainless steel and other food-grade materials to ensure hygiene and longevity. It is designed for easy cleaning and maintenance, reducing the risk of cross-contamination between batches.
Versatile Applications: DSI Direct UHT units are suitable for use with a variety of liquid foods and beverages, including dairy products (e.g. milk, cream), juices, soups, sauces and flavored beverages. Particularly effective for products with strict sterilization requirements, such as dairy products and high-acid beverages.
Advantage
Superior product quality: The direct steam injection method ensures a rapid rise in temperature, helping to preserve the taste, color and nutritional content of your product while effectively sterilizing it.
Extended shelf life: UHT sterilization significantly extends the shelf life of products without the need for preservatives or refrigeration, helping to reduce waste and improve product stability.
Lower operating costs: Energy-efficient designs and automated systems help reduce energy consumption and labor costs. An advanced heat recovery system further reduces overall operating expenses.
Flexible and adaptable: DSI Direct UHT units can be easily adapted to handle a variety of liquid products, making them a versatile solution for a variety of food and beverage applications.

>> FAQ
Q: What is a DSI Direct UHT unit?
A: A direct UHT (ultra-high temperature) unit is a heat treatment system used to sterilize liquid food and beverages by rapidly heating to ultra-high temperatures (typically 135°C to 150°C) in a very short period of time. This process kills harmful microorganisms while preserving the taste, color and nutritional value of the product.
Q: How does a DSI Direct UHT unit work?
A: Direct UHT units use steam to inject heat directly into the product, rapidly raising its temperature to the desired sterilization level. The steam mixes with the product and the heat of the steam sterilizes the liquid. Rapid heating minimizes heat exposure and reduces loss of flavor and nutrients.
Q: What is the capacity of DSI Direct UHT unit?
A: The capacity of the unit depends on the specific model. It can process hundreds to thousands of liters per hour. Custom models can be designed to meet specific production needs.
