What is a water bottle filling machine?

As bottled water production shifts from decentralized processes to integrated, efficient operations, the 750LPH water bottle filling machine, with its integrated capabilities for “water production – cleaning – filling – sealing – labeling – and testing,” has become the preferred choice for small and medium-sized bottled water companies to reduce production line costs.

This integrated system automates the entire process from raw water treatment to labeling. It not onlt eliminates the gaps in traditional separate equipment but also precisely matching the production needs of mainstream bottle sizes from 500ml to 2L, providing a one-stop, ready-to-use solution for bottled water production.

Integrated water bottle filling machine system

The core competitiveness of the water filling machine lies in its “integrated design”. Because it realizes a fully closed production loop through five collaborative modules.

1. Raw water treatment:

Firstly, this water treatment system integrates a three-stage treatment process: pretreatment + deep filtration + sterilization and disinfection. It is suitable for various raw water types, including municipal tap water and groundwater.

In the pretreatment stage, a multi-media filter with a filtration accuracy of up to 5μm is used to remove suspended matter such as silt, rust, and residual chlorine from the raw water.

In the deep filtration stage, we use an reverse osmosis membrane and switch it according to water quality requirements to effectively remove heavy metal ions, microorganisms, and organic matter. Thus, the treated water meets drinking water standards.

In the sterilization and disinfection stage, we install an ultraviolet disinfection device to ensure that the effluent microbial indicators meet the standards.

The treated pure water is temporarily stored in food-grade stainless steel tanks with built-in level sensors, which are linked to the subsequent filling module for liquid supply.

2. Precision filling:

Secondly, it utilizes negative pressure quantitative filling technology, achieving a filling accuracy of ≤±0.5%. A built-in liquid level sensor in the liquid storage tank automatically triggers a liquid supply signal when the liquid level is low, ensuring continuous, uninterrupted filling.

The sealing module integrates a capping mode and an automatic cap loading track. After sealing, a negative pressure detector verifies the seal in real time.
The automatic labeling module is equipped with a rolling labeling head and supports self-adhesive labels. Labeling speeds match production line speeds.

Why choose water bottle filling machine?

1. Cost optimization:

The entire machine occupies only 2-3 square meters. So, the integrated design reduces equipment procurement costs by approximately 25%.

2. Improved efficiency:

Each module operates synchronously, with no waiting time for process connection. The production efficiency of the entire machine is 30% higher than that of the split line, and the average daily production capacity can reach 1.6-1.8 tons (calculated based on 20 hours of production).

3. Food grade guarantee:

We make the parts that come into contact with the liquid and the bottle from food-grade materials (304 stainless steel, food-grade silicone seals), and these materials meet food safety standards.

Where can water bottle filling machine be used?

In terms of application scenarios, this device is particularly well-suited for two types of businesses:
First, startup bottled water companies, which can quickly build a complete production line.

Second, small community water plants, which can meet the production capacity needs of local distribution (averaging 1-2 tons per day).

How to maintain the device?

• Operational specifications:

Before starting the machine, check all module parameters on the PLC touchscreen. After startup, observe the first product test results. Only after they pass muster can mass production begin.
Before shutting down the machine, perform a CIP cleaning process to empty the liquid storage tank.

• Regular maintenance:

Replace filling valve seals and UV lamps monthly, and lubricate and maintain servo motors quarterly to extend equipment life.
