Helical coil heat exchange · complete fluid processing lines
Beikai engineers sterilization systems and complete processing lines for dairy, beverage, concentrated-liquid and oral-liquid products — built around helical coil heat exchange to deliver lower heat damage, longer shelf life and lower energy consumption.
SYSTEMS
A complete equipment platform for fluid sterilization and thermal processing
Ultra-high-temperature sterilization at 137 °C with a 4-second hold. The concentric helical coil gives a uniform temperature field and a short heat path, cutting energy use and fouling for continuous dairy and beverage operation.
At 125 °C the heat load approaches pasteurization while still achieving ESL-grade sterilization, extending chilled shelf life to 21–45 days.
Aseptic breather valves, a steam barrier and sterile-air breathing, with full SIP sterilization and CIP cleaning — interlocked with the coil sterilizer for aseptic buffer storage.
Multi-station acid, caustic and hot-water circulation covering piping and vessel interiors with no dead legs — shorter cleaning cycles and stable hygienic conditions in continuous production.
Sanitary tanks and custom blending systems covering buffering, blending and homogenization, supplied as part of complete sterilization lines.
Custom design and fabrication to customer process requirements — frames, piping, heat exchangers and electrical control delivered as one package with on-site installation and commissioning.
TECHNOLOGY
Helical coil heat exchange — better performance, longer equipment life
Furosine is an early marker of the Maillard reaction. The higher the value, the greater the thermal damage to protein — and the larger the loss of flavour and nutrition.
Source: internal pilot-plant trials on the same raw-milk batch; furosine determined per NY/T 939-2016.
The helical coil shortens the heat path and evens the temperature field, keeping sterilization temperature stable and controllable.
Enhanced turbulence continuously renews wall-adjacent fluid, stripping the hot boundary layer that causes local overheating and thermal damage.
Lower furosine formation means significantly less loss of flavour and nutrition — or higher sterilization intensity at the same heat load.
High heat-transfer efficiency cuts steam consumption and temperature-difference losses; heat recovery brings total energy use below conventional tubular systems.
Integrally bent coils with few welds and no square retention corners give smooth internal surfaces and full CIP coverage.
Without a stagnant boundary layer, proteins and minerals deposit less on the wall, extending continuous run time.
| Process | Temperature | Furosine (finished) | Shelf life | Notes |
|---|---|---|---|---|
| Pasteurization | 72–78 °C | 5–12 mg | Chilled 5–7 days | Good nutrient retention, short shelf life |
| Conventional tubular UHT | 135–150 °C | 150–200 mg | Ambient 6 months | High heat damage, noticeable flavour loss |
| Steam infusion | 150 °C / 0.1 s | 15–70 mg | Ambient 6 months | Low heat damage, high capital cost |
| Beikai low-damage process | 125 °C / 4 s | 35–55 mg | Chilled 21–45 days | Heat load close to pasteurized, shelf life greatly extended |

The process inactivates all vegetative pathogens (E. coli, Salmonella, Listeria) and Bacillus cereus spores. Thermophilic survivors such as Geobacillus stearothermophilus are permitted, as they do not grow at 2–6 °C chilled storage. The process is positioned for ESL extended-shelf-life chilled products.

ABOUT
Focused on fluid sterilization and intelligent equipment
Jiangsu Beikai Intelligent Equipment Technology Co., Ltd. is a dedicated manufacturing and sales company for fluid processing equipment. Built on helical coil heat-exchange technology, we supply sterilization systems and complete lines for dairy, beverage, concentrated-liquid and oral-liquid products — from pre-treatment and sterilization through aseptic storage, filling interface and CIP.
The company was established to focus the group's extensive engineering and manufacturing experience in the beverage and dairy industries on one product line. We keep investing in helical coil heat exchange and low-heat-damage sterilization, and we treat every machine we build as our own reputation.
