Product Overview
This tubular ultra-high temperature sterilization machine is specially used for continuous sterilization of fruit juice, tea beverages, milk beverages and similar liquid products. It adopts all-stainless steel frame and pipeline structure, equipped with international first-tier brand electrical components, and realizes fully automatic control via Siemens touch screen and PLC system.
The equipment can be seamlessly connected with upstream and downstream equipment such as homogenizers and deaerators. It covers the whole process from CIP cleaning, equipment self-sterilization to material sterilization, with full automatic control and data recording. While ensuring thorough sterilization effect, it maximally retains the original flavor, nutrition and sensory quality of products, making it core sterilization equipment for medium and large beverage and food production lines.
Equipment Features
- High thermal efficiency Up to 90% heat recovery efficiency, greatly reducing steam and cooling water consumption and lowering production operation cost.
- Low scaling & long running cycle Small temperature difference between heating medium and material. The heat exchange tubes adopt straight tube design with high heat exchange efficiency and less scaling, effectively extending the continuous working time of the sterilizer.
- High automation level The whole process including CIP cleaning, equipment self-sterilization and material sterilization can be automatically controlled and recorded, reducing manual operation and ensuring stable production quality.
- Precise & reliable sterilization control Sterilization temperature is accurately controlled. Steam pressure, flow rate and material flow rate are all strictly and automatically regulated to ensure stable and reliable sterilization effect.
- Aseptic hygienic design The inner wall of material pipelines adopts advanced polishing and automatic welding technology. The pipeline design realizes fully automatic cleaning, and the whole-process self-sterilization function ensures the sterility of the whole system.
- High system safety All system components are high-performance and high-reliability products. Pressure protection measures and alarm systems are equipped for steam, hot water and materials to ensure safe production.
- High system reliability Core components including material pumps, hot water pumps, various valves, electrical components and actuators of the control system are all world-famous brands, ensuring long-term stable operation.
- Built-in CIP cleaning system Comes with integrated CIP cleaning function, which can automatically complete the cleaning of the whole pipeline system without disassembly, meeting food hygiene production requirements.
Working Principle
The equipment adopts the principle of ultra-high temperature instantaneous sterilization (UHT). Materials flow continuously in the closed tubular heat exchanger, and go through three stages: preheating, high-temperature sterilization and cooling in sequence.
First, the low-temperature material enters the heat recovery section to preheat by absorbing the heat of the sterilized high-temperature material; then it enters the heating section and is rapidly heated to 115–137℃ by steam or hot water, and maintains the set sterilization time in the holding tube to completely kill harmful microorganisms and spores; finally, the sterilized high-temperature material enters the cooling section to be cooled to the required filling temperature.
The whole process is completed in a fully closed food-grade stainless steel pipeline, with no external pollution and short high-temperature duration, which can ensure thorough sterilization while maximally retaining the original flavor, color and nutritional components of the product.
Process Parameters
Three standard process routes are available to match different filling methods:
- For aseptic packaging: 5℃ → 65℃ (homogenization) → 137℃ (3–5s holding) → 20–25℃
- For hot filling: 5℃ → 65℃ (homogenization) → 115℃/125℃ (5–15s holding) → 88–90℃
- For warm filling: 5℃ → 65℃ (homogenization) → 115℃/125℃ (5–15s holding) → 75–78℃
