Pet Food Granule Rotary Packing Machine | High-Speed Precision

Pet Food Packaging Machine: Granule Rotary Packing Machine for Optimal Efficiency

As the pet food market continues to boom—driven by increasing pet ownership and premium feeding trends—manufacturers face growing pressure to deliver consistent, high-quality packaging at scale. Whether you’re producing dry dog food, cat kibble, turtle pellets, or bird seed, the right packaging equipment ensures product freshness, accurate portioning, and streamlined operations.

The Granule Rotary Packing Machine is engineered to meet these demands. Designed for high-speed, precise filling of granular products, this solution is ideal for small packages (10–1000 g) of pet food varieties. Below, we explore how this machine transforms pet food packaging from a labor-intensive bottleneck into a seamless, automated process.

Why Automated Packing Matters in Pet Food

Manual or semi-automatic packaging methods struggle with:

• Inconsistent weights, leading to giveaway or underfill

• Slow throughput, limiting production capacity

• Variable seal quality, risking freshness and shelf life

• High labor costs and training requirements

By contrast, the Granule Rotary Packing Machine delivers:

• Uniform fill weights with ±0.1 g accuracy

• Throughput up to 80 bags/min, depending on product density

• Airtight seals that preserve flavor and nutrition

• Reduced labor via end-to-end automation

Core Features of the Granule Rotary Packing Machine

1. Rotary Multi-Station Design

At the heart of the Granule Rotary Packing Machine is a rotary carousel with multiple stations handling pouch pick-up, date coding, pouch opening, filling, sealing, and discharge simultaneously. This continuous motion drives high-speed packaging.

2. Precision Weighing Heads

Equipped with an integrated multi-head weigher, the machine measures granular pet foods—such as dog kibble or cat food pellets—with exceptional consistency. Operators can configure up to 10 weigh heads to meet specific fill ranges from 10 g to 1 000 g.

3. Gentle Product Handling

Fragile products like turtle pellets or crunchy cat treats require minimal drop height and gentle transfer. The HMD design includes shock-absorbing conveyors and smooth chute transitions to prevent breakage.

4. Flexible Pouch Formats

Whether you need pillow bags, gusseted pouches, or stand-up bags with reclosable zippers, this machine adapts to various film types and pouch styles. This flexibility supports diverse package sizes and retail preferences.

5. Food-Grade Construction

Constructed from SUS304 stainless steel, all product-contact surfaces meet FDA and EU food safety regulations. Quick-release components facilitate washdown and sanitation, crucial for preventing cross-contamination between flavors or formulas.

Benefits for Pet Food Manufacturers

Boosted Production Capacity

With speeds of up to 80 packs per minute, manufacturers can scale output to meet seasonal peaks or expanding distribution agreements—a critical advantage in a competitive pet food market.

Enhanced Portion Control

Accurate weighing heads minimize product giveaway and ensure each bag contains the intended number of kibble pieces or pellets, protecting profit margins and compliance with labeling regulations.

Improved Shelf Life

Airtight, heat-sealed pouches lock in freshness, extending the shelf life of sensitive pet food ingredients like omega-rich fish meal and probiotics.

Reduced Labor Costs

By automating filling, sealing, and bag discharge, the Granule Rotary Packing Machine can reduce labor requirements by up to 60%, freeing staff for quality control and new product development.

Greater Flexibility

Easily switch between different pet food formulas—dog food today, bird feed tomorrow—without extensive retooling, thanks to programmable settings and quick-change servo adjustments.

Case Study: Scaling a Regional Dog Food Brand

Background: A regional dog food brand struggled to meet demand using semi-automatic scales and hand-sealers. Their six-person packaging crew could fill only 5 000 bags weekly.

Solution: Installation of the Granule Rotary Packing Machine with eight weigh heads and a triple-seal module.

Results:

• Weekly output soared to 20 000 bags

• Labor headcount reduced by 50%

• Package weight consistency improved from ±5 g to ±0.2 g

• Customer complaints about underfill virtually eliminated

Return on investment was achieved in under 10 months through increased sales capacity and material savings.
