Tubular Sterilizer for Milk, Juice, and Other Beverages

The Weishu Tubular Sterilizer is a high-performance thermal processing system engineered for the rigorous demands of the modern beverage and dairy industries. Designed to handle products ranging from low-viscosity milk to high-viscosity juices with particulates, this tubular sterilizer ensures absolute biological safety while preserving the product’s organoleptic properties.

At Weishu, our engineering philosophy focuses on balancing high-temperature sterilization with minimal thermal impact. By utilizing advanced multi-tube heat exchanger technology, our tubular sterilizer achieves precise UHT (Ultra-High Temperature) processing, providing a stable aseptic environment that extends product shelf life without compromising flavor or nutritional integrity. For industrial operators, Weishu represents a fusion of mechanical reliability and processing excellence.

Key Features & Functionality

We have engineered the Weishu system to directly address the primary operational challenges in liquid food processing:
Optimized Thermal Exchange Efficiency: Our heat exchangers utilize corrugated tube technology to induce turbulence at lower flow rates. This design maximizes the heat transfer coefficient, ensuring rapid heating and cooling cycles that significantly reduce the risk of product “burn-on” or scaling.

• Robust Aseptic Barrier Design: Security is paramount in aseptic processing. The Weishu system features reinforced mechanical seals and sterile barriers at all critical junctions. Its tubular structure is specifically designed to withstand the high back-pressures typical of viscous material transport, offering greater durability than traditional plate heat exchangers.
• Automated Process Control & Compliance: The system is powered by a fully integrated PLC (Siemens/Allen-Bradley) that monitors temperature, pressure, and flow in real-time. With automated CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocols, we ensure your production line meets the strictest global food safety standards, including FDA and CE.
• High Energy Recovery: Our regenerative heat design allows for up to 90% energy recovery, significantly reducing steam and cooling water consumption, which directly lowers your total cost of ownership (TCO).

• Dairy Processing: ESL (Extended Shelf Life) milk, flavored milk, and yogurt-based beverages.

FAQ

Q1: How does the Weishu system minimize scaling and clogging during long production runs?
A: Our corrugated tube design creates a “self-cleaning” turbulent flow. This minimizes the buildup of proteins and minerals on the internal surfaces, extending the interval between CIP cycles and maintaining consistent heat transfer efficiency throughout the production day.

Q2: Is this sterilizer suitable for products containing pulp or fibers?
A: Yes. Unlike plate heat exchangers which have narrow gaps, our tubular design provides a wide, unobstructed flow path. This allows the system to process particles and fibers without the risk of blockages or mechanical shearing.

Q4: Can this unit be integrated into an existing aseptic filling line?
A: Absolutely. We provide standard communication protocols to ensure the Weishu sterilizer synchronizes seamlessly with your downstream aseptic fillers and packaging equipment, allowing for a fully integrated “end-to-end” production flow.
