Vtops Developed a New Kind of Negative Pressure Liquid Filling Machine

As China’s leading packaging and filling machinery manufacturing company, VTOPS has recently developed a new linear negative pressure liquid filling machine. The machine first evacuates the packaging container to form negative pressure. Then, fill the packaging container with liquid. So, the company named it a negative pressure liquid filling machine. Filling accuracy and consistency are achieved by creating a vacuum environment, flexible level control, and automated filling heads. Its high degree of automation also means that production speed and efficiency are greatly improved, providing a perfect solution for the liquid filling needs of various industries.

Working Principle of Negative Pressure Liquid Filling Machine

The working principle of the negative pressure liquid filling machine is based on negative pressure technology, which achieves high-precision liquid filling by creating a vacuum environment during the liquid filling process. First, the machine uses a vacuum pump to extract the air from the container so that the inside of the container is under negative pressure. Afterward, the liquid in the liquid storage tank is filled into packaging containers under standard atmospheric pressure. Finally, the vacuum blower sucks away all excess liquid in the packaging container to keep the liquid in all packaging containers at a horizontal level. This series of steps ensures that the amount of liquid in each container is accurate.

Comparison between Negative Pressure Filling Technology and Traditional Filling Technology

There are some significant differences and comparative advantages between negative pressure technology and traditional technology in liquid filling. Here’s a comparison between the two:

Accuracy and Consistency:

1. Negative Pressure Technology: Negative pressure technology enables highly precise and consistent liquid filling through vacuumization and level control. This means the amount of liquid in each container is very accurate, reducing waste and inconsistency.
2. Traditional Technology: Conventional technology may be more susceptible to human error and, therefore, may not be as accurate and consistent as negative pressure technology.

Prevent Bubbles and Leaks:

1. Negative Pressure Technology: By creating a vacuum environment during liquid filling, the formation of bubbles can be effectively prevented. For liquids that are prone to bubbles, the machine will eventually suck out all the foam in the mouth of the bottle. Inhaled foam and liquid will go into the reservoir without waste.
2. Traditional Technology: Traditional technology may require more operator skill and experience to ensure no air bubbles in the liquid and is prone to leakage issues.

Degree of Automation:

1. Negative Pressure Technology: Negative pressure liquid filling machines generally have a higher degree of automation, reducing the need for manual intervention and improving production efficiency.
2. Traditional Technology: Traditional technology may require more manual operations, including manual control of liquid flow and adjustment of fill volume.

Adapt to Different Containers:

1. Negative Pressure Technology: Negative pressure technology can adapt to different types and sizes of containers because it draws liquids through a vacuum without requiring a specific device to accommodate each container.
2. Traditional Technology: Traditional technology may require more adjustments and replacement parts to accommodate different container types.

Production Speed:

1. Negative Pressure Technology: Negative pressure liquid filling machines can always work at higher speeds because they are highly automated equipment that can work continuously.
2. Traditional Technologies: Traditional technologies may be limited in speed as they may require more operator intervention.

Application Scope

Negative pressure vacuum filling machines are widely used in many industries, including food, beverages, alcohol, and daily necessities. It is an effective device for efficiently filling various liquids and liquid products. The specific application scope includes but is not limited to the filling of liquid products such as liquor, wine, rice wine, various beverages, soy sauce, vinegar, alkali, paint, pesticides, oyster sauce, concentrated juice, etc. This equipment fills by creating a negative pressure environment when filling the container, and the filling head moves downward. This filling method avoids the ingress of oxygen or other contaminants, making it widely used in product packaging and production processes across multiple industries.

Technical Parameters:

1. Filling Nozzles: 4-16 nozzles (configured as required)
2. Capacity: 10ML-5000ML (configured as required)
3. Filling Form: Equal Liquid Level Negative Pressure Multi-head filling
