LJ Water Bath Pasteurization Line is engineered as a specialized sterilization solution for crystal boba (agar jelly pearls) — the essential chewy topping used in modern bubble tea, fruit tea, yogurt drinks, and dessert shops worldwide.
This high-precision three-stage system seamlessly integrates a 90°C water bath pasteurization tunnel (15-minute dwell), a rapid cooling section, and a high-efficiency air drying unit. The continuous mesh belt conveyor ensures uniform heat treatment of every sealed pouch or cup of crystal pearls, destroying harmful microorganisms while precisely preserving the pearls' unique crispy-chewy texture and translucent glossy appearance.Fully fabricated from food-grade SUS304 stainless steel, this turnkey line is the trusted choice for bubble tea raw material suppliers, central kitchen factories, and frozen dessert topping manufacturers targeting global export markets including Southeast Asia, Middle East, North America, and Europe.
Unlike generic sterilizers that can soften or melt heat-sensitive gel products, our line uses precisely controlled 90°C ±1°C water bath temperature with optimal 15-minute dwell time — tested and validated to kill pathogens while maintaining the crystal pearl's signature crispy bite .
Three-Stage Seamless Flow:
Products move continuously from pasteurization → cooling → air drying without manual transfer, eliminating recontamination risk and reducing labor costs by 60%.
Uniform Heat Penetration:
The water bath immersion design ensures 360° heat distribution around every individual pouch, unlike spray-type systems that may leave cold spots in stacked or irregularly shaped packages.
PLC touch screen with real-time temperature logging and HACCP-compliant data recording for export quality audit trail requirements.
Smooth mesh belt with adjustable speed protects delicate pearl packaging from damage during transfer between stages.

Crystal Boba / Agar Pearl Manufacturers: High-volume production of sealed pouch crystal pearls for bubble tea chain supply (brands like Mixue, Heytea, ChaPanda).
Popping Boba / Juice Pearl Producers: Sterilization of popping boba filled with fruit juice syrup, requiring gentle heat treatment.
Konjac Jelly & Diet Jelly Factories: Pasteurization of low-calorie konjac snack cups for the health food export market.
Fruit Jelly Cup Manufacturers: Continuous sterilization of multi-flavor fruit jelly cups for retail distribution.
Bubble Tea Central Kitchens: In-house production and sterilization of fresh crystal pearls for direct store delivery.
Feeding Zone: Sealed pouches of crystal pearls enter the conveyor.
Pasteurization Stage (90°C / 15 min): Products are fully immersed in precisely temperature-controlled water bath, ensuring uniform heat penetration to the core of each pearl.
Rapid Cooling Stage: Products pass through chilled water section, rapidly reducing core temperature to below 25°C to lock in texture.
Air Drying Stage: High-pressure air knives remove surface moisture from packaging for clean, dry finished products.
Discharge Zone: Sterilized, cooled, and dried products are ready for cartoning and cold chain storage.
Q: Why is water bath pasteurization better than spray type for crystal boba?A:Crystal boba is a heat-sensitive gel product. Water bath immersion provides uniform, gentle heat distribution that sterilizes without overcooking. Spray-type pasteurization can cause uneven heating, resulting in some pearls softening or losing their crispy texture — a critical quality failure for bubble tea brands.
Q: Can the 90°C / 15-minute parameters be adjusted for different products?A:Yes. Both temperature (65-95°C) and dwell time (10-60 minutes) are fully adjustable via the PLC touch screen. Our engineering team also provides process parameter optimization support for your specific product formula and packaging size.
Q: We are a startup boba factory. Can this line grow with our business?A:Absolutely. We offer modular designs with capacities from 500kg/h to 5000kg/h. You can start with a smaller configuration and expand modules as your export orders grow.
Q: Does this line support HACCP and export certification requirements?A:Yes. The PLC system records time-temperature data for every batch, providing auditable sterilization records required by FDA, EU, and other international food safety authorities.
