High-grade EPDM sealing rings and wear-resistant UMPE plastic components ensure extended service life, while motor-driven gear transmission guarantees steady, vibration-free performance throughout production.

High-Efficiency Water-Saving Rinsing Design The bottle washing system adopts high-performance nozzles that reach every corner inside bottles for thorough inner-wall cleaning, effectively cutting rinse water consumption. A dedicated splash shield above the nozzles prevents water splashing, and an adjustable recovery tank with recycling pipelines further improves water resource utilization for an eco-friendly, cost-efficient process.

Quick & Flexible Bottle Format Changeover Bottle type conversion is simple and time-efficient — only the infeed and outfeed star wheels need to be replaced. In addition, the height of the rotary assembly can be flexibly adjusted to accommodate bottles of varying heights, greatly enhancing production flexibility and changeover efficiency for multi-SKU beverage manufacturing.

Filling Part

High-quality Bearings and Stable Transmission: The rotating part uses large flat-plane bearings and German Igus maintenance-free bearings. The power system of the machine is driven by a motor and transmitted through gears, ensuring stable operation and easy maintenance.

Advanced Hygienic Isobaric Filling Valve Design Engineered with international leading sanitary concepts, the filling valve features fast filling speed, minimal sanitary dead spots, fewer sealing components and precise liquid level control. This optimized structure enables highly efficient, accurate isobaric filling while simplifying cleaning procedures to meet strict beverage food safety standards.

Dual-Mode Bottle Lifting Mechanism for Versatile Production Two bottle lifting modes are available to adapt to diverse production scenarios. The mechanical mode uses a guide slider paired with a cam mechanism for precise guiding and smooth, steady lifting, ideal for high-precision filling requirements. The pneumatic mode, driven by lifting cylinders with rapid response, positions bottles at the filling station quickly to support high-speed, large-scale continuous production.

Intelligent PLC-Controlled Liquid Replenishment A magnetic liquid level switch on the liquid cylinder works seamlessly with the PLC system to precisely regulate the feed pump and pneumatic inlet valve. It realizes automatic real-time material replenishment, maintains stable liquid level and filling pressure inside the tank, and guarantees continuous production with consistent filling accuracy.

Full CIP Circulation Cleaning for Food-Grade Hygiene The filling system is equipped with a professional CIP circulation system, which effectively cleans all pipelines, liquid tanks, filling valves and matching cleaning dummy cups. It thoroughly removes product residue and ensures sanitary conditions throughout the filling system, providing reliable compliance with beverage production hygiene requirements.

Capping Part

Precision Manufacturing and Stable Transmission: The main components of the capping machine are precisely processed by a CNC machining center and go through a complete heat treatment. The power system of the machine is driven by a motor and transmitted through gears, ensuring the machine's durability and smooth operation.

Intelligent Cap-feeding: With a bottle-feeding detection switch, it automatically stops cap-feeding when no bottles are present, reducing cap waste. The cap-locking cylinder at the connection of the cap-dropping guide rail and cap-dialing disc accurately ensures no cap supply without bottles, effectively saving material costs.

Stable Capping: The magnetic constant-torque capping head provides a reliable and stable capping effect. Additionally, the adjustable torque meets the tightening requirements of different caps, guaranteeing product packaging quality.

Prevention of Cap-less Bottles: The photoelectric switches enable the machine to stop automatically when caps are missing, effectively improving product qualification rates by preventing the production of cap-less bottles.

Adjustable Height, Diverse Adaptability: The height of the capping head's rotating part is adjustable, enabling it to fit different bottle heights, enhancing equipment versatility for various production needs.

Water Treatment System

Our water treatment systems are fully custom-engineered to your raw water conditions. After reviewing your water analysis report, we design a tailored solution combining pre-filtration, reverse osmosis (RO), ultrafiltration (UF) and ozone/UV sterilization for deep purification — effectively removing contaminants, reducing hardness and ensuring compliance with drinking water standards.

Carbonated Beverage Processing System

Our CSD mixing systems are custom-engineered around your unique beverage formulas, providing a complete pre-filling preparation solution for carbonated soft drinks. The full system comprises syrup melting tanks, blending tanks, heating & cooling units, sterilizers and supporting modules. All wetted parts use high-grade 304/316 stainless steel with precision welding and polishing, paired with optimized process design and fully automated control. Every configuration can be tailored to your specific production requirements.

Process Flow: Syrup Melter → Syrup Transfer Pump → Syrup Filter → Primary Blending Tank → Beverage Transfer Pump → Dual-stage Filter → Secondary Blending Tank → Dual-stage Filter → UHT Sterilizer → Homogenizer → CIP System

Bottle Blowing System

Our PET bottle blow molding machines support fully custom bottle shapes and serve a wide range of beverage applications. We offer two configurations to fit different production scales:

Semi-automatic blow molder: Manual operation with low upfront investment, ideal for small-batch production and startup plants.

Automatic blow molder: High-level automation for medium to high-speed production lines, ensuring stable output with reduced labor demand.

Automatic models produce PET bottles from 100ml to 2,000ml, commonly used for water, soda and cola bottles. All bottle profiles can be customized to your exact design requirements.

Carbonated Drink CO2 Mixer

Our carbonating mixer is the core processing unit for carbonated soft drink production, engineered to precisely blend syrup, treated water and carbon dioxide for consistent taste and stable carbonation retention.

Syrup is prepared in sugar melting and blending tanks, filtered and pumped into the mixer. Meanwhile, process water goes through vacuum degassing to improve CO₂ absorption. The system proportions water and syrup to your exact formula, cools the blend via a plate heat exchanger, then dissolves CO₂ under controlled pressure to achieve optimal, long-lasting carbonation.

Labeling Machine

We deliver customized final packaging solutions aligned with your needs and market demand, with three mainstream label options for bottle — PVC shrink sleeve, OPP hot-melt glue and self-adhesive labels — each paired with dedicated labeling equipment. As refined label design effectively boosts brand recognition and market appeal, we recommend referencing local mainstream products when making your selection.

Bottle Packging System

Individual bottled water requires secondary packaging to withstand long-distance transportation and storage. We provide a range of end-of-line packaging solutions, including PE shrink wrapping, carton packing and film-with-tray packaging, each paired with purpose-built equipment.

PE shrink film packaging is the most common choice for bottled water plants due to its low material cost, while carton packaging is typically selected for premium bottled water or glass bottle lines.
