Dust-Free Packaging Filling Lines
When producing mixtures of loose materials and filling packaging with small portions, very high accuracy and filling speed are required. It is important to use a universal system that meets customer requirements in a practical way – it is ideal for dust-free filling of various types of packaging, such as cardboard boxes or barrels, to the required weight – from 10 to 100 kg. At InterProcess, we approach each project individually, taking into account all customer wishes and needs, with attention to the smallest details. The lines for dust-free filling of cardboard boxes and barrels meet strict hygiene requirements and guarantee easy operation. Depending on customer requirements, it is possible to design the device in accordance with the ATEX directive or FDA requirements.
The dust-free filling station can be placed directly under mixers or buffer tanks, or the material can be fed from a BIG-BAG. The main element of the entire line is a volumetric screw feeder, which controls the filling process, together with a hopper with a geometry that facilitates material flow. The hopper is equipped with two fill sensors – minimum and maximum. When the minimum value is reached, the system automatically fills the hopper to the maximum value without interrupting the operation of the device. Thanks to various types of screens, we can be sure that no foreign particles will end up in the final packaging. Depending on the type of container being filled (bags, boxes, barrels), the station can be equipped with various heads with an inflatable seal, which ensure a tight connection and a dust-free filling process. In addition, the line is connected to a dust extraction system. Thanks to its modular design, it is extremely easy to adapt to customer needs. It is a universal solution for different container sizes thanks to a system that allows for quick adjustment of the distance between the rollers and the head. Our lines can be equipped with wheels, allowing them to be moved freely around the plant. In the model presented, we have equipped the device with an additional, certified scale at the customer’s request.

Principle of operation—lines for dust-free filling of containers
In the case of bags or boxes with inserts, the filling process is performed manually. The operator places the bag or film from the box on the head, closes the clamp, and activates the seal pumping process with a foot switch, which ensures a completely tight connection. Then, the dust-free filling process is started using a second foot switch. Dosing takes place automatically until a specified weight is reached, after which the system unseals the connection, allowing the container to be freely disconnected. The system can also be designed to operate fully automatically when filling rigid containers, such as barrels.
Continuous replenishment of material
The raw material is fed into the main chamber of the dosing device from a hopper with a geometry that facilitates material flow, equipped with two level sensors – minimum and maximum. When the minimum value is reached, the controller automatically starts filling the hopper to the maximum level without interrupting the packaging process.

Reliable flow
Screw dispensers are equipped with a horizontal agitator driven by a separate electric motor, operating at a constant speed, which ensures complete filling of the dispensing element and protects against material jamming. For products that are particularly difficult to dispense, it is possible to install an additional vertical agitator.

Precision scales
At InterProcess, we know how to use strain gauge measuring systems in the most optimal way, and our designs are reliable and dependable solutions for weight measurement. We offer platform scales of various sizes, including certified ones, made of carbon and stainless steel, tailored to the needs of our customers.

Weighing automation
We offer special weighing controllers from the Dutch company PENKO with dedicated MFL (Mono Fill) software for our lines, enabling a simple and fully automated process of dust-free filling of various types of containers.

Dust-free filling process
The bag from the container should be placed on the head and the clamp closed – the container is then pre-mounted. When the operator presses the foot switch, the seal is inflated, ensuring a completely tight connection and a dust-free filling process.

Versatility
Thanks to the use of a screw feeder with different types of feeding elements depending on the material being fed, no challenge is too great for us. We can feed virtually any type of dry bulk material – both free-flowing and difficult-to-flow, easily aerated, prone to uncontrolled flow or clumping.

Spiral
Application for materials:
- difficult to flow (e.g., flour, soda, granules)
- fine and sticky, and prone to accumulating on the guide pin (e.g., cocoa, titanium white)
- consisting of large particles that can accumulate, causing high friction between the guide pin and the surface of the flow tube
- requiring much better hygienic conditions (e.g., foodstuffs)

Screw with guide pin
Application for materials:
- free-flowing and very loose (e.g., salt, sugar)
- easily aerated, with a tendency to flow uncontrollably (e.g., carbonates, gypsum)
- highly abrasive (e.g., quartz sand)
- brittle (e.g., flakes, instant coffee)
