Pet Food Processing Automation

Metromotion Controls automates pet food plants across Melbourne and Victoria, covering raw material handling, batching, extrusion, packaging integration and traceability.

HomeIndustriesPet Food

Pet food manufacturing brings together raw material variability, batching, thermal processing, packaging and traceability. Metromotion Controls designs controls for recipe enforcement, intake, dosing, process stability, quality records and production reporting.

Sector Challenges

Problems we solve

01
Raw material variability and intake control

Protein meals, grains, oils and micronutrients have different handling needs and quality constraints. Sites need dependable weighing, dosing and route validation to avoid formulation drift.

02
Mixing, extrusion and moisture consistency

Process windows can shift with ingredient characteristics and upstream variation. Without coordinated control and feedback, product texture and nutritional targets can drift.

03
Synchronising process and packaging operations

Process interruptions can destabilise packaging flow, while packaging stops can create upstream product handling issues. Integrated state management is needed to protect yield.

04
Traceability from ingredient lot to finished pack

Pet food operations require rapid traceability for quality assurance and market response. Manual records are too slow for efficient containment and analysis.

Our Approach

How we deliver

We understand the process behind a pet food plant, from raw material intake and gravimetric dosing through mixing, extrusion, drying and coating, which lets us program recipe-driven control from the P&ID and a plant walkthrough rather than a long functional specification. We deploy raw material handling controls with validated routing, bin inventory visibility and weigh-scale integration to manage dosing accuracy. Ingredient identity checks and transfer confirmations are embedded into sequence logic to reduce operator error and formulation drift.

Batching and mixing strategies use parameter-governed recipe and phase control with alarmed tolerances and automated exception capture. For extrusion and drying stages, we integrate the measurements that govern texture and nutritional targets, including barrel temperature, pressure, screw speed and moisture, into trend-driven operational dashboards so process engineers can hold the window and recover quickly after a disturbance.

Our integration approach connects process assets with packaging lines through coordinated buffering logic, transfer permissives and state machines that support controlled recovery after disturbances. This reduces waste and minimises unstable restarts.

For traceability, we link ingredient receipt data, batch execution records, in-process quality checks and packaging identifiers within a common data architecture. The result is faster recall analysis, clearer supplier performance insight and stronger quality governance.

04

Information systems: historian, SQL repositories and reporting integrations for quality and production teams.

HACCP-aligned control checkpoints for recipe and process assurance.
FSANZ and customer quality documentation requirements.
AS/NZS machinery and electrical safety compliance for integrated lines.
Structured commissioning and validation records for regulated production environments.
Common Questions

Frequently asked

How do you handle recipe security in pet food automation?

We apply role-based recipe control, approved parameter ranges and change logging for every recipe revision. Operator workflows include confirmation checkpoints so formulation-critical settings cannot be altered without traceable authorisation.

Can extrusion control be improved without replacing all hardware?

In many cases, yes. We often improve performance through software refactoring, better signal conditioning, additional instrumentation and operator guidance while retaining suitable field hardware and minimising capital disruption.

What traceability response time can be expected?

An integrated architecture lets lot-to-pack trace queries run directly against captured lot and batch records rather than reconstructing them by hand, which is usually the main driver of slow investigations. Actual response time depends on lot granularity, instrumentation quality and data discipline, which we address during design and commissioning.

Do you understand the extrusion and drying process, or only the controls?

Both. Metromotion Controls programs pet food plants from the P&ID and a walkthrough because we understand the process behind the equipment. That means working with the variables that actually move product quality and yield, including gravimetric dosing accuracy, mixer homogeneity, extruder barrel temperature, pressure and screw speed, and dryer moisture and retention, then holding those windows under real ingredient variability rather than treating each machine as an isolated controller.
