Product Details

Working Principle

The UHT Sterilizer operates on the ultra-high temperature instantaneous sterilization principle. Liquid raw materials first pass through a regenerator (heat exchanger), where heat from the outgoing sterilized product preheats the incoming raw material, significantly reducing energy consumption. The preheated material is then rapidly heated to 135-150°C via direct steam injection or indirect heat exchangers (plate or tube designs). After holding at this temperature for 2-5 seconds in a holding tube to ensure complete microbial inactivation, the material is quickly cooled to storage or aseptic filling temperature. Throughout the process, a PLC system with HMI interface precisely controls temperature, flow, and pressure, minimizing nutrient loss while guaranteeing consistent sterilization efficacy.

Features

Energy Efficiency & High Output:

90%+ heat recovery via the regenerator cuts energy costs; continuous operation supports large-scale production.

Advanced Automation:

HMI-controlled PLC system enables real-time monitoring of critical parameters; integrated CIP (Clean-In-Place) system ensures thorough sanitation with minimal manual effort.

Food-Grade Construction:

Built with 304/316L stainless steel and sanitary clamp fittings, compliant with FDA/3A hygiene standards.

Modular Design:

Includes a balance tank (stabilizes material flow), optional homogenizer (enhances texture), and sterile air system (prevents post-sterilization contamination).

Compact & Durable:

Small footprint fits industrial spaces; quick-disassembly components simplify maintenance.

Technical Highlights

Heating Technology:

Choose between direct steam injection (fast, suited for heat-stable products) or indirect plate/tube heat exchangers (high efficiency, easy cleaning; plate type for low-viscosity liquids, tube type for high-viscosity or particulate-containing materials).

Control Technology:

Precision sensors and PID-controlled actuators maintain ±0.5°C temperature stability; a deviation interlock system automatically diverts substandard material to ensure quality.

Aseptic Technology:

Sterile air system maintains positive pressure in critical zones; seamless welding and polished surfaces (Ra ≤ 0.8μm) inhibit microbial growth.
