ALFRA Solutions

ALFRA’s solutions for finished product handling can collect large volumes of finished products (up to 13,500 lbs / 6.000 kg) in exact quantities such as kibbles, flakes, granulates and other fragile products and can discharge at multiple locations within the plant.

Because these systems work without conveyor belts, pneumatic tubes, chain conveyors or other types of conventional transport, there is a minimal risk of cross-contamination. ALFRA’s equipment for feeding packaging lines are easy to clean, require less building height and can be installed in brownfield as well as greenfield situations.

Kibble mixing, fast and clean

More and more pet food manufacturers offer a multi kibble mix, or a mix of kibble and bits. ALFRA’s movable bulk scale hoppers collect batches kibble from a large number of bins (up to 60 bins) and bring these to a mixer or straight up to various packaging lines. These big scales can move in multiple directions and speed up your process, increase your flexibility and eliminate the risk of cross-contamination and kibble damage.

Preventing cross-contamination with the petfood dosing slide

This special dosing slide for finished petfood kibbles is equipped with a smart operating system that is self-learning and features a unique design that will prevent cutting kibbles during the dosing process while maintaining a high capacity and accuracy. A clean swipe function and vibrations remove remaining product from the dosing slide to prevent any contamination of colors and shapes.

Movable weighing mixer for product blending and bulk outloading

ALFRA’s solutions for kibble and end-of-line mixing improve the flexibility of your operation and eliminate the risk of cross-contamination by moving the mixer to the product silos instead of the other way around. The advanced mobility eliminates the need for additional mechanical ways of internal transfer which are often expensive and form a risk of de-mixing or even damage to the final product.

Frequently asked questions

To prevent damage to fragile products, it is best to avoid conventional transport methods like conveyor belts or pneumatic tubes. Using movable bulk scale hoppers allows you to collect and transfer exact quantities—up to 6,000 kg (13,500 lbs)—smoothly and directly to packaging lines or mixers, significantly reducing the risk of product breakage.

Cross-contamination can be minimized by utilizing mobile weighing and mixing solutions that travel directly to the product silos, rather than transporting the product through shared mechanical lines. This approach keeps the system cleaner and prevents unwanted mixing of colors, shapes, or recipes between batches.

Yes, modern feeding systems for packaging lines are highly adaptable. They require less building height than traditional conveyors and can be easily installed in both greenfield (newly built) and brownfield (existing) manufacturing facilities.

Specialized dosing slides designed for pet food feature a smart, self-learning operating system and a unique mechanical design that safely handles fragile kibbles. This ensures high capacity and accuracy without physically cutting or crushing the product as it moves through the line.

Absolutely. Movable bulk scale hoppers can collect batches from a large number of storage bins (sometimes up to 60) and bring them either to a central mixer or directly to various packaging lines. This speeds up the process and provides the flexibility needed for multi-kibble mix products.
