A complete fruit juice production line is a closed-loop system integrating automation and precision, encompassing nine core pieces of equipment. It comprehensively ensures the quality, safety, and taste of the juice from source to finished product. The first step in production is water treatment. Through multi-stage processes including quartz sand filtration, activated carbon adsorption, precision filtration, and ultraviolet disinfection, impurities, odors, heavy metals, and microorganisms are removed from the raw water, ultimately producing pure water that meets food-grade standards, laying the foundation for subsequent juice processing.
Next, a blow molding machine uses high-pressure air to blow-form heated and softened PET preforms into beverage bottles of specified sizes. The entire process is automated, ensuring uniform bottle shape and wall thickness to meet filling requirements. As the core of the production line, the juice processing system is even more complex. Fresh fruit is washed, sorted, and crushed before entering the juicer. The extracted juice is then centrifuged and filtered to remove pulp residue. Subsequently, the sugar and acidity are adjusted according to the product formula, and finally, it undergoes UHT instantaneous sterilization, killing harmful bacteria while preserving the juice's nutrients and natural flavor to the greatest extent possible.
The CIP (Clean-In-Place) online cleaning system is crucial for ensuring production hygiene. It performs high-temperature, high-pressure cleaning and sterilization of key components such as juicers, filling machines, and pipelines without disassembling the equipment, effectively preventing cross-contamination between different batches and significantly improving production efficiency. After sterilization, the qualified juice is precisely injected into bottles by filling machine. The equipment uses quantitative filling technology, keeping errors within a very small range, and is equipped with a seal detection device to prevent leakage.
After filling, the bottles enter a cooling channel where cold water spray quickly cools the juice to room temperature, preventing flavor loss caused by high temperatures and reducing the risk of spoilage in subsequent packaging stages. The cooled bottles are then processed by a labeling machine, which accurately affixes labels containing brand, ingredients, and shelf-life information to the bottle body, ensuring a high degree of adhesion and preventing detachment. Subsequently, a laser marking machine prints unique production dates, batch numbers, and other traceability information on the bottle body, with clear and durable lettering for easy product quality traceability. Finally, the packaging machine completes the boxing or film wrapping process for the finished products, adapting to different packaging specifications as needed. The boxed products are then ready for warehousing. The entire production line achieves full-process automation and linkage, taking into account both large-scale production and quality control, which is the core guarantee for the industrial production of fruit juice.
