This automatic rotary premade pouch packaging system features multiple stations arranged in a circular layout. Freeze-dried pet food packaging is handled seamlessly through each stage of the process:
1. Pouch Loading & Opening: Pre-made pouches (such as stand-up bags or flat pouches) are loaded into a magazine hopper. A robotic arm or vacuum suction picks up each pouch and places it into the rotary indexing carousel. At the first stations, the pouch is securely gripped and opened—mechanical grips and air jets (or vacuum) ensure the pouch is fully open for filling. For pouches with resealable zippers, a device can pre-open the zipper to allow unobstructed filling.
2. Filling with Freeze-Dried Pet Food: Once the pouch is open, a precise dosing system fills it with the freeze-dried pet food product. This machine can integrate various fillers, such as a multi-head weigher for chunky freeze-dried pieces or an auger filler for powdery blends. High-accuracy scales drop the exact amount of product into each pouch, ensuring consistent weight with minimal variation (typically to within ±1 gram accuracy). The gentle fill process preserves the shape and integrity of delicate freeze-dried kibble or treats.
3. Nitrogen Flushing (Optional): Before sealing, the machine injects food-grade nitrogen gas into the pouch (a process called modified atmosphere packaging, or MAP). This nitrogen flush displaces oxygen inside the package, which is critical for freeze-dried foods. By pushing out oxygen to low residual levels (often under 3% O₂), the machine greatly reduces oxidation, moisture absorption, and microbial growth. The result is an extended shelf life and preserved nutrients for the pet food, since freeze-dried foods must be in airtight packages to prevent spoilage. (Nitrogen is an inert, safe gas comprising 78% of air, so it won't affect the food's taste or safety while it keeps it fresh.)
4. Inspection & Quality Checks: As pouches move through the stages, the machine employs built-in sensors and inspection systems. It verifies that each pouch is present, correctly opened, and properly filled before sealing. Standard safeguards include a "no pouch, no fill" and "no pouch, no seal" mechanism, so product is never dispensed if a pouch isn't in place or open. This prevents spills and avoids wasting product or creating messes.
5. Sealing the Pouch: With the pouch filled and flushed, the next station heat-seals the top of the pouch. Heat seal jaws press the pouch material together, melting the inner layers to form a strong, airtight seal. This creates a hermetic seal that locks out air and moisture, vital because freeze-dried pet foods rely on airtight pouches to maintain their quality. Our machine's sealing system is carefully calibrated for consistent temperature, pressure, and dwell time, so each bag gets a perfect seal. (For added seal integrity, some models have two sealing stages: a primary seal and a secondary cooling or crimp seal.)
6. Discharge: The final station releases the finished pouches onto an output conveyor. The sealed, nitrogen-flushed pet food pouches emerge neatly and are ready for case packing or further downstream handling. The end result is a line of uniform, pillow or stand-up pouches filled with premium freeze-dried pet food, each package reliably sealed for maximum freshness and shelf life.
Throughout this rotary workflow, the machine's intermittent motion indexing ensures each pouch stops at exactly the right position for each operation. The overall process is fully automated and continuous – as one pouch is being filled, another is being sealed, another is being discharged, and so on – optimizing throughput. An intuitive touchscreen HMI (Human-Machine Interface) allows operators to monitor the process in real time, showing station statuses, fill weights, and any fault alarms in clear text. In short, from loading empty pouches to outputting sealed products, the entire packaging cycle is handled with precision and minimal human intervention.
Our multihead weigher is engineered for exceptional accuracy and speed:
High-Precision Load Cells: Each head is equipped with sensitive load cells to ensure precise weight measurements, reducing product giveaway.
Flexible Weighing Options: Adjustable parameters to accommodate various jerky sizes and shapes.
Optimized Speed: Efficiently handles high-speed operations without compromising on accuracy, enhancing productivity.
Designed for premade pouches of almost any style. It works with flat 3- or 4-side sealed pouches, stand-up pouches (doypacks), premade gusseted bags, and pouches with or without resealable zipper closures. Whether your pet food is sold in a simple flat pouch or a premium stand-up pouch with a zipper and tear notch, this machine can fill and seal it. (It can even handle special formats like spouted pouches for liquids, though freeze-dried products typically use non-spouted bags.)
