3 in 1 Monobloc Juice Filling Machine for 300ml 330ml 500ml Fruit Juice Bottles 2000 to 3000 BPH
Working Principle and Core Advantages of 3 in 1 Monobloc Juice Filling Machine
The 3 in 1 Monobloc Juice Filling Machine integrates three core processes—bottle washing, juice filling, and capping—into a single unit, realizing a fully automated and continuous production workflow tailored for 300ml, 330ml, and 500ml fruit juice bottles with a production capacity of 2000 to 3000 bottles per hour (BPH). The working principle starts with the bottle washing stage: empty bottles, which can be directly supplied by our bottle blow molding machine, are precisely positioned and cleaned by high-pressure pure water (treated by our water treatment system) jets, removing impurities and ensuring hygiene. Subsequently, the cleaned bottles are transferred to the filling station, where pressure filling technology (optimized for different fruit juice viscosities, from thin clear juices to thick pulp-containing ones) is adopted to inject juice into bottles with consistent volume control. Finally, the filled bottles move to the capping station for automatic lid feeding and tight capping, completing the entire packaging process in one seamless operation without secondary contamination.
This monobloc machine boasts distinct core advantages for new juice factories targeting mid-scale production. Firstly, its integrated design eliminates the need for separate conveying equipment between washing, filling, and capping, significantly reducing factory floor space occupancy and lowering initial infrastructure costs. Secondly, it features precise filling accuracy with an error margin of less than 0.5%, specifically calibrated for 300ml, 330ml, and 500ml bottle specifications, effectively reducing juice waste and optimizing production costs. All parts in contact with juice are made of food-grade 316L stainless steel, complying with FDA and CE standards, while the sealed production environment preserves the freshness and nutritional value of fruit juice. Additionally, the 2000-3000 BPH capacity perfectly matches the production demand of emerging juice factories, balancing efficiency and cost-effectiveness, and it can be easily integrated with our juice processing system for a full production chain.
Key Components and Structural Features of 3 in 1 Monobloc Juice Filling Machine
The 3 in 1 Monobloc Juice Filling Machine consists of four key integrated components: the bottle washing unit, filling unit, capping unit, and intelligent PLC control system. The bottle washing unit is equipped with adjustable high-pressure nozzles that adapt to the three specified bottle sizes (300ml, 330ml, 500ml), ensuring thorough cleaning without damaging bottle bodies. The filling unit adopts anti-drip and anti-foam filling heads, a critical design for fruit juices (especially those with pulp) to prevent spillage, foam formation, and juice oxidation. The capping unit features an automatic lid unscrambler and precision capping mechanism, compatible with various standard caps (such as screw caps and crown caps) for fruit juice bottles. The intelligent PLC control system serves as the "brain" of the machine, coordinating all processes seamlessly and enabling easy parameter adjustment.
Structurally, the machine adopts a compact monobloc design with a robust stainless steel frame, ensuring stability and durability during long-term continuous operation. The modular structure of each functional unit (washing, filling, capping) facilitates easy maintenance, part replacement, and future upgrades, which is particularly friendly for new factory operators with limited technical experience. Moreover, the machine is designed with quick-change parts for switching between 300ml, 330ml, and 500ml bottle sizes—this adjustment can be completed within 30 minutes, greatly enhancing production flexibility. The ergonomic touch screen control panel allows operators to set parameters (such as filling volume, capping torque, and production speed) and monitor real-time operation status intuitively, reducing the learning curve and operational errors. Its durable construction also minimizes downtime, a key factor for new factories to maintain stable production.
Application Scope and Seamless Compatibility with Complete Production Lines
This 3 in 1 Monobloc Juice Filling Machine is specifically designed for filling various fruit juices, including clear juices (e.g., apple juice, orange juice), cloudy juices, and pulp-containing juices (e.g., mango juice, peach juice), in 300ml, 330ml, and 500ml bottles—the most popular packaging sizes in the global fruit juice market. With a production capacity of 2000 to 3000 BPH, it is ideally suited for new juice factories that aim to enter the mid-scale market, balancing production efficiency and initial investment costs. Beyond fruit juices, it can also be used for filling other liquid food products with similar viscosity, such as fruit nectars, vegetable juices, and even low-viscosity sauces, expanding the product portfolio for new factories and increasing market competitiveness.
A key advantage of our 3 in 1 Monobloc Juice Filling Machine is its seamless compatibility with our complete set of production equipment, forming an integrated and efficient fruit juice production line. It can be directly connected to our bottle blow molding machine (for producing 300ml-500ml PET bottles), bottle unscrambler, and water treatment system—ensuring that every link from bottle manufacturing to juice filling meets strict hygienic and quality standards. Additionally, it can be paired with our labeling machine, film shrink/carton packing machine, and even sachet liquid packing machine (for complementary small-pack products) to achieve end-to-end automated production. This one-stop solution eliminates the hassle of equipment matching from multiple suppliers for new factories, reduces intermediate handling links, and lowers overall production costs. Our professional team can also customize the machine's parameters according to specific production needs, such as adapting to special juice formulas or packaging requirements, making us the ideal partner for new juice factory investmet.
