How Does The BIB Filling Machine Work?

Nowadays, in the food packaging world,  BIB filling machines, you know, the ones that are also called bag-in-box filling machines, are really popular for packing liquid foods because they've got some great advantages. These machines work really well and are super accurate, helping foods stay fresh longer and making them easier to carry and sell. So, how do these BIB filling machines actually fill all sorts of liquid foods into those fancy multi-layered boxes and bags so precisely?

The BIB filling machine is a complex system integration, mainly including several key parts such as bagging system, filling system, exhaust system, control system, and cleaning system. These systems work together to ensure the smooth progress of the filling process and the excellence of product quality.

● Bagging system

responsible for accurately placing pre-prepared bags in the filling position, laying the foundation for subsequent filling work. At present, machines with relatively small production capacity use manual bagging, while those with large production capacity use automatic bagging systems to increase production capacity.

● Filling system

Composed of inlet and filling head, it is the core component of BIB filling machine. The inlet is responsible for receiving and transporting the liquid to be filled, while the filling head precisely injects the liquid into the bag of the box through a precise mechanical structure and control system. At present, BIB filling machines are divided into two types of filling systems: sterile and non sterile, with the difference being whether there is a sterile chamber for steam sterilization. Obviously, sterile BIB filling machines are more expensive than non sterile BIB filling machines.

● Exhaust system

Before filling, the air in the inner bag is effectively discharged through the clean steam of the exhaust system to avoid air residue affecting product quality and shelf life.

● Control system

As the "brain" of the entire filling process, the control system is responsible for monitoring and adjusting various parameters, such as liquid flow rate, metering, filling pressure, etc., to ensure the accuracy and stability of the filling process.

● Cleaning system (including diagram)

After completing the filling task, the cleaning system will comprehensively clean and disinfect the filling head and conveying pipeline to meet food safety standards and ensure the hygiene and safety of the next filling.

Preparation:

Before filling, it is necessary to make preparations by placing the sterile bag in the correct position, ensuring that it is placed directly below the filling head and can accurately receive the liquid without leakage.

Inner bag exhaust:

After placing the bags in the box, it is necessary to exhaust the air inside the bags through the exhaust system to ensure product quality and extend shelf life.

Liquid filling:

Next, the inlet of the BIB filling machine will be responsible for conveying the liquid into the equipment, adjusting the flow rate and velocity of the liquid through the control system, and the filling head will be responsible for accurately filling the liquid into the BIB bag.

Filling monitoring:

During the filling process, the accuracy and consistency of the filling are monitored by the control system. The sensors of the BIB filling machine can detect other parameters such as liquid level and filling pressure, in order to adjust the filling parameters in a timely manner.

Packaging sealing:

Finally, the liquid product is filled into BIB bags and undergoes inner bag sealing to ensure the bag's sealing and prevent leakage.

Cleaning and maintenance:

After the filling process is completed, the filling head and conveying pipeline need to be cleaned and disinfected through a cleaning system to ensure the hygiene and safety of the product.

Once the filling process wraps up, it's important to clean and disinfect the filling head and conveyor pipeline using a cleaning system. This step ensures the hygiene and safety of your product.

The key to BIB filling is the precision and reliability of its control system. This system guarantees that liquid products are filled into BIB bags accurately, while maintaining the hygiene, safety, and overall quality of the food packaging.
