Automatic Barreled Mineral Water Filling Production Line

Product Details
This barreled mineral water filling production line is the core integrated equipment for large-scale water plants. It integrates processes including empty cap removal, external brush cleaning, inner bucket disinfection, multi-stage pure water rinsing, atmospheric pressure quantitative filling, automatic capping and crimping, and finished product conveying into a fully closed-loop automated workflow. The entire operation runs in a sealed and clean environment, which drastically reduces the risk of secondary pollution during empty bucket transportation.
The equipment features two mainstream configurations: the linear model boasts a compact structure with a small footprint and low maintenance threshold, making it suitable for small and medium-sized start-up water plants with a capacity of 200-400 barrels per hour. The rotary model adopts a multi-station rotary platform, with a production capacity of 600 barrels per hour up to over 2000 barrels per hour. It delivers superior operational stability, and is tailored for large branded water plants with a daily output of 10,000-barrel level.
The filling module uses submerged anti-drip filling valves that ensure high positioning accuracy of the barrel mouth. During the filling process, the valve nozzle rises slowly along with the ascending liquid level, preventing water splashing and foaming. No residual liquid drips to contaminate the barrel body after filling is completed. The whole line is equipped with a complete intelligent protection mechanism, featuring functions such as no filling when no barrel is detected, automatic shutdown in case of missing caps, automatic output counting, and real-time pop-up warning of fault codes. Key pneumatic components are selected from imported brands, enabling the whole machine to run continuously for more than 72 hours without failure.
This production line supports modular expansion. The front end can be connected to RO reverse osmosis / ultrafiltration water treatment systems, while the rear end can be linked with bagging machines, palletizers, as well as visual inspection and inkjet coding equipment. It also reserves an interface for MES system connection to achieve full production data traceability from raw water to finished barrels, which fully meets the compliance control requirements for the production process specified in the new national standard for drinking water.

Frequently Asked Questions
Is the switching and debugging between different barrel specifications troublesome?
The equipment is equipped with an adjustable barrel mouth positioning device, with multiple sets of barrel type parameters pre-set via the PLC. When switching from 5-gallon barrels to 3-gallon barrels, you only need to select the corresponding formula on the touch screen, and the equipment will automatically adjust the filling nozzle height, clamping force and filling volume. The format change time is shortened from the traditional 30 minutes to just a few minutes, without the need for extensive mold replacement.
Can the cleaning and disinfection of the equipment meet food-grade hygiene requirements?
All water-contact pipelines and filling heads support quick disassembly, and can also be directly connected to a CIP (Clean-in-Place) system. Combined with the ozone water final rinsing station, it can effectively kill residual microorganisms in the barrels. The water quality indicators fully comply with the GB 5749 Hygienic Standard for Drinking Water.
If you want to expand production later when the initial capacity is small, can the old equipment still be reused?
The equipment adopts a modular architecture design. You can purchase a basic single-unit filling machine in the initial stage. After the order volume increases in the subsequent stage, you can directly add a barrel washing module and a conveying module on the basis of the existing equipment to seamlessly upgrade it to a fully automatic whole line. There is no need to replace the core filling main unit, which avoids the waste of secondary procurement.
Are additional configurations required for use in areas with high-hardness water sources?
For the high-hardness water source scenarios in northern China, a two-stage reverse osmosis + softening pretreatment module can be matched. The equipment will automatically adjust the membrane flux to ensure that the final produced water quality stably meets the standards. The concentrated water recovery rate can be increased to 78%, reducing the wastewater treatment cost.
What about after-sales guarantee and operation and maintenance support?
Regular services include a 1-year complete machine warranty and lifetime maintenance. In most regions of China, engineers are promised to arrive on site within 48 hours. Some models also support remote cloud maintenance, which can warn of potential faults in advance through remote system diagnosis to reduce the loss caused by unexpected production shutdown.
