A double-pipe coil UHT sterilizer for instantaneous heat treatment of fresh milk, soy sauce, beverages, wines and soybean milk. Steam-heated with high transfer efficiency, food-grade stainless construction and automatic temperature control, it integrates easily into turnkey beverage and water production lines.
Producers who process everything from fresh milk to soy sauce want one flexible sterilizer that treats each liquid fast and gently. The coil UHT sterilizer from Zhonglian Machinery is engineered for that versatility, serving beverage, juice and water plants across Central Asia, Africa, Southeast Asia and South America as a hygienic module inside complete turnkey production solutions.
Overview
At its core sits a double-pipe coil heat exchanger that transfers heat efficiently, saves energy and keeps operation simple. Because product spends only a very short time at high temperature, nutrient loss stays minimal.
The unit sterilizes fluid products such as fresh milk, soy sauce, beverages and wines, and handles soybean milk and liquid pharmaceuticals just as well. Paired with a homogenizer, it can also process high-viscosity materials like sweetened condensed milk.
Key Features
- Energy-saving coil core – the double-pipe coil exchanger delivers strong heat transfer and recovery, lowering running energy while staying simple to operate and cheap to maintain.
- Instantaneous UHT treatment – a very brief high-temperature pulse sterilizes thoroughly yet preserves nutrients, natural flavour and colour.
- Broad material range – handles milk, soy sauce, beverages, wines, soybean milk and liquid pharmaceuticals, plus high-viscosity products with a homogenizer.
- Food-grade hygiene – stainless wetted parts resist corrosion and clean easily, meeting food and pharmaceutical standards.
- Stable continuous run – compact integrated build with precise temperature control for consistent industrial output.
- Low-maintenance design – intuitive structure, easy operation and a low failure rate keep long-term cost down.
How It Works
The conveying pump feeds raw material into the double-pipe coil exchanger, where the recovery section preheats it using residual heat from outgoing sterilized product.
Material then enters the heating section and is driven quickly to ultra-high sterilization temperature by steam, staying there only briefly inside the coil to achieve instantaneous sterilization.
Afterwards the hot sterilized stream gives up its heat to incoming cold material in the exchange section, recovering waste heat and cooling rapidly at the same time.
The extremely short heating window sterilizes completely while minimising damage to nutrients, flavour and colour – the key to a high-quality finished product.
