5000BPH Automatic 3-in-1 PET Bottle Carbonated Soft Drink Filling Machine

Rinsing Part

Stable Operation & Low Maintenance: The rotary system adopts large plane bearings and genuine German Igus maintenance-free bearings for smooth, reliable operation and reduced routine maintenance costs. High-grade EPDM seals and wear-resistant UMPE plastic parts extend service life, while motor-driven gear transmission ensures steady, vibration-free production.

Water-Saving High-Efficiency Rinsing: The bottle washing system uses high-performance nozzles for thorough inner-wall cleaning with lower water consumption. A dedicated splash shield prevents water spillage, and an adjustable recovery tank with recycling pipelines improves water utilization and cuts operating costs.

Quick Bottle Format Changeover: Bottle type conversion is fast and simple — only the infeed and outfeed star wheels need replacement. The rotary assembly height is flexibly adjustable to fit different bottle heights, greatly improving production flexibility for multi-SKU beverage manufacturing.

Filling Part

Stable Transmission with Premium Bearings: The rotary unit adopts large flat-plane bearings and German Igus maintenance-free bearings. Driven by a motor with gear transmission, it delivers smooth operation and easy maintenance.

Sanitary Isobaric Filling Valves: Designed with leading global sanitary standards, the filling valves feature fast filling speed, minimal dead spots, fewer sealing parts and precise liquid level control. The optimized structure simplifies cleaning and meets strict beverage food safety requirements.

Dual-Mode Bottle Lifting Mechanism: Two lifting modes adapt to diverse production scenarios: mechanical mode with guide slider and cam structure for high-precision filling; pneumatic mode with fast-response lifting cylinders for high-speed continuous production.

PLC-Controlled Automatic Liquid Replenishment: A magnetic level switch on the liquid cylinder works with the PLC system to regulate the feed pump and pneumatic inlet valve. It maintains stable liquid level and filling pressure for consistent filling accuracy during continuous production.

Full CIP Circulation Cleaning System: The filling system is equipped with a professional CIP circulation unit to thoroughly clean all pipelines, liquid tanks, filling valves and dummy cups. It eliminates product residue and ensures full compliance with beverage production hygiene standards.

Capping Part

Precision Machining & Stable Transmission: Core capping components are precision-machined by CNC centers with full heat treatment. Motor-driven gear transmission ensures high durability and smooth, consistent operation.

Intelligent Cap Feeding: Bottle detection switches automatically pause cap supply when no bottles are present. A cap-locking cylinder at the guide rail interface reinforces this function, cutting cap waste and material costs.

Stable Constant-Torque Capping: The magnetic constant-torque capping head delivers reliable, uniform capping results. Adjustable torque accommodates different cap specifications and guarantees consistent packaging quality.

Missing Cap Auto-Shutdown Protection: Photoelectric switches trigger automatic machine shutdown when caps are absent. This eliminates cap-less finished bottles and effectively improves product qualification rate.

Adjustable Height for Broad Compatibility: The height of the capping head rotary assembly is adjustable to fit varying bottle heights, boosting equipment versatility for multi-format production.

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.

Q1: Are you a trading company or a direct manufacturer?

A: We are a dedicated manufacturer with over 22 years of industry experience in beverage filling and packaging. Based in Zhangjiagang (only 2 hours from Shanghai), our factory is equipped with advanced technology to provide high-quality equipment at factory-direct prices. We warmly welcome you to visit our facility to see our machines in action.

Q2: What equipment is included in a complete CSD production line?

A: A complete CSD production line can include water treatment, syrup preparation, vacuum deaeration, CO2 mixer, beverage chiller, isobaric rinsing-filling-capping monoblock, bottle warmer if needed, labeling machine, coding system, shrink wrapping or carton packing machine, and conveyors.

Q3: What is isobaric filling and why is it important for CSD production?

A: Isobaric filling, also called counter-pressure filling, means the pressure inside the bottle is balanced with the pressure in the filling tank before the beverage enters the bottle. This is important for carbonated soft drinks because sudden pressure drops can cause foaming, CO2 loss, unstable fill levels, and product waste.

Q4: Can it handle bottles of different sizes?

A: Yes. The bottle guide rails, filling height and capping head position are all adjustable. It is compatible with PET bottles from 250ml to 2L. Bottle changeover can be completed by adjusting parameters and replacing a small number of parts.

Q5: Do you provide overseas installation and training service?

A: Yes. We send experienced technical engineers to your factory for on-site installation, commissioning and operator training to ensure your production line starts up smoothly and on schedule.

Q6: What is the warranty period of the equipment?

A: The whole machine comes with a 12-month warranty. We provide long-term technical support and original spare parts supply after the warranty expires.
