Key Equipment Models Used

1. Oil Filling Machine:

This machine is at the heart of the filling process. Equipped with PLC control and servo-driven technology, this machine ensures accuracy within ±0.5% fill volume

It is capable of handling a variety of liquids, from thick oils like olive oil to low-viscosity liquids such as vegetable oil. With its high-speed operation and accuracy, the machine can fill up to 1,200 bottles per hour, depending on the liquid type and bottle size. The system uses feedback loops to constantly monitor and adjust the filling volumes, minimizing errors and product waste.

2. Capping Machine:

Utilizing a pneumatic system, this machine applies caps securely on bottles of various sizes. It accommodates different types of caps, including screw caps and snap-on caps. This versatility allows for smooth operation even when changing product lines. The automated capping process ensures that each bottle is sealed tightly, preventing leaks during transportation and ensuring product integrity.

3. Labeling Machine:

This machine is designed for high-speed applications, capable of applying labels to a wide range of bottle sizes and shapes. With multiple models available (e.g., high-speed sleeve labeling machine, single-side automatic labeling machine, and round bottle automatic labeling machine), the system ensures consistent branding and regulatory compliance. It can label up to 1,000 bottles per hour, depending on the model and bottle type. This feature ensures that products maintain their visual appeal and meet the necessary legal requirements.

4. Conveyor System:

A crucial part of the production line, the conveyor system ensures seamless movement of bottles from one machine to the next. It reduces manual handling, speeds up the process, and minimizes the risk of contamination or damage during transit. The integration of sensors allows for smooth operation and automatic adjustments, making the system adaptable to various production speeds.

• There are many models of labeling machine of our factory to meet different bottle size. For example:

       -High-speed sleeve labeling machine + steam shrinking machine

       -Single side automatic labeling machine

       -Flat automatic labeling machine

       -Double side automatic labeling machine

       -Horizontal automatic labeling machine

       -Round bottle automatic labeling machine

       -Desktop small flat automatic labeling

       -Desktop small automatic round bottle labeling machine

How It Works

1. Preparation:

Before starting the filling process, all machines must be calibrated and cleaned. The liquid filling machine is pre-loaded with the specified oil product, and any settings for bottle size or fill volume are input into the system via the PLC screen.

2. Filling:

The liquid filling machine begins the process by automatically filling each bottle to the predetermined volume. Thanks to servo-driven technology, the filling volume is highly accurate, reducing waste and ensuring that each bottle contains the right amount of oil.

3. Capping:

After filling, bottles are transferred to the capping machine, where caps are applied automatically. The pneumatic system ensures a tight seal, preventing leaks or spills. This system offers both manual and automatic capping options, which can help optimize labor costs while ensuring the security of the package.

4. Labeling:

Next, bottles pass through the labeling station. High-speed machines apply labels with precision, ensuring that each bottle is correctly marked with product information and branding. With different models available for varying bottle shapes, the labeling process is both flexible and efficient.Brand Consistency: Choose from sleeve, front/back, or round-bottle labelers applying 1,000 labels/hour. Ensures compliance with FDA or EU regulations for ingredient lists and branding.

5.Smart Conveyor System

Seamless Integration: Sensor-driven conveyors adapt to production speeds, reducing bottlenecks. Ideal for hygienic environments with easy-clean designs.

6. Packaging:

Finally, the filled, capped, and labeled bottles move to the packaging area, where they are carefully boxed and prepared for shipment. Additional equipment, such as palletizers and case sealers, are used to handle large quantities, improving packaging efficiency and reducing human error.

Traditional Methods vs. Modern Automated Systems

Traditional Filling Methods:

In the past, oil factories relied on manual or semi-automated processes. Workers would fill bottles by hand or using less advanced machines. These systems were often slower, more prone to human error, and less efficient at managing product wastage. Inaccurate filling and inconsistent sealing were common issues, leading to higher costs and lower customer satisfaction.

Modern Automated Filling Systems:

Compared to traditional methods, modern filling lines offer a host of advantages:

Speed: A modern filling machine can fill up to 1,200 bottles per hour, significantly outpacing manual filling methods, which might only manage 100-200 bottles per hour.

Accuracy: Servo technology ensures that the fill volumes are consistently accurate, reducing overfills and underfills that waste product and affect profit margins.

Cost Savings: With automation, factories can reduce labor costs by up to 30%. Plus, with better control over the filling process, the overall cost per unit decreases.

Real-World Application Case Studies

Improved Efficiency: A recent case study from a major oil company showed that switching from manual filling to automated systems increased production by 50%, allowing the factory to handle larger volumes without additional labor costs.

Waste Reduction: By using servo-driven filling machines, one factory reduced product waste by 12%, translating to significant cost savings. With traditional methods, the variability in fill volume often led to overfilling or underfilling, contributing to waste and customer complaints.

Adaptability in Production: A company producing both edible and industrial oils found that automated equipment could easily switch between different liquid types and bottle sizes, ensuring quick response to market demands without halting production.

Core Advantages of Automated Filling Production Lines

1. Efficiency:

Automating the filling, capping, and labeling processes boosts throughput and minimizes downtime. For example, modern filling machines can fill up to 1,200 bottles per hour, compared to just a few hundred with traditional methods. Customizable machines can adjust to various liquid viscosities and production speeds, ensuring optimal efficiency for different product types.

2. Accuracy:

Advanced servo-driven technology in filling machines minimizes errors and ensures consistent fill volumes. This precision ensures compliance with quality standards and reduces the risk of customer dissatisfaction. As a result, oil factories can maintain product consistency, which is crucial for brand reputation.

3. Adaptability:

The ability to easily change between different bottle sizes and liquid types makes these systems perfect for businesses that need to diversify their product offerings. This adaptability significantly reduces downtime during production line changes.

4. Cost Savings:

Automated systems reduce reliance on manual labor, saving up to 30% in labor costs. Additionally, by minimizing product waste, these systems help factories save significantly on raw materials.

Conclusion

The modern filling production line in an oil factory is a game-changer in terms of efficiency, accuracy, and cost-effectiveness. By automating key processes like filling, capping, labeling, and packaging, oil factories can achieve higher production rates, reduce waste, and maintain product quality, all while responding flexibly to market demands. These advancements not only contribute to improved factory operations but also set a higher standard for product consistency and customer satisfaction.
