As demand for freeze-dried pet food continues to grow, many brands find themselves at the same turning point: moving from pilot development to full production. Early product development often happens in small batches. Teams test formulations, refine texture, and dial in the process using pilot equipment or small-scale runs.
That phase is critical. But scaling a successful pilot product into consistent, repeatable production requires a different process. At Parker Freeze Dry, this transition is something our team works through regularly with pet food manufacturers preparing to scale.
“Pilot production is about learning how a product behaves. Production manufacturing is about delivering the same result every time.” - Test Run Manager
Pilot Production Is Designed for Learning
Pilot runs serve an important purpose. They allow product teams to experiment and refine a recipe without committing to full production volumes.
In pilot environments, operators often have more flexibility to adjust variables like:
• tray loading
• product thickness
• drying time
• process temperatures
Those adjustments help teams learn how a product behaves during freeze drying.
But pilot production is designed for learning and iteration, not long-term manufacturing.
Production Requires Process Stability
When a product moves into commercial production, the goals change.
The process must now deliver consistent results across:
• larger product loads
• multiple batches
• different operators and production shifts
Freeze drying is particularly sensitive to process conditions. Changes in load size, product density, or tray configuration can affect how moisture moves through the product during drying.
What worked well during pilot testing may need to be refined for production environments.
This isn’t a sign that the product failed development.
It simply reflects the reality that pilot testing and production manufacturing operate under different constraints.
Why Scaling Changes the Process
Moving from pilot to production introduces new variables that influence drying behavior and throughput.
These include:
-
Load size and product distribution
-
Production systems process significantly larger volumes. Ensuring product is loaded consistently across trays becomes more important.
-
-
Drying cycle design
-
Cycle parameters that work for small batches may not deliver the same results when product loads increase.
-
-
Throughput expectations
-
Pilot runs prioritize experimentation. Production systems must balance quality with predictable cycle times.
-
-
Repeatability
-
Manufacturing systems must produce consistent results across many cycles, not just one successful batch.
-
Designing a process that accounts for these factors is essential for scaling successfully.
“Scaling isn’t just about increasing capacity. It’s about making sure the process behaves the same way every time you run it.”- Jerad Ducklow
Bridging the Gap Between Pilot and Production
One of the most important steps in scaling freeze-dried products is evaluating how the process behaves under larger production conditions.
This is where many brands benefit from structured testing.
By running products through larger-scale systems, teams can evaluate:
• drying performance at higher volumes
• product structure and texture
• cycle stability and repeatability
• throughput expectations
These insights help manufacturers refine their process before committing to full production.
“Test runs give manufacturers visibility into how their product behaves at scale. That insight can prevent major adjustments later.” -Matt Graunke
How Parker Freeze Dry Supports the Scaling Process
At Parker Freeze Dry, much of our work with pet food manufacturers focuses on this transition from pilot to production.
Our team regularly collaborates with brands to evaluate how their products behave during larger-scale freeze drying and how processing parameters may need to evolve as production grows.
Because freeze drying is highly dependent on process design, these early evaluations can provide valuable insight into:
• cycle development
• tray loading strategies
• process stability
• equipment capacity planning
Understanding these factors early can make the scaling process significantly smoother.
Planning for Production Scale
For brands preparing to increase production, it helps to begin thinking about scale earlier in the development process.
Questions worth exploring include:
• How will the product behave at larger load sizes?
• Will the drying cycle remain stable across repeated runs?
• How will production capacity align with projected demand?
• What adjustments may be required when transitioning to production equipment?
Addressing these questions early allows brands to move into production with greater confidence.
Planning Your Next Step
Most pet food manufacturers hit the same point. The freeze-dried product works in pilot runs, orders are climbing, and the question changes from “can we freeze dry this?” to “can we make enough of it, consistently, at commercial volume?”
For many products, the answer is yes. Getting there takes more than a bigger freeze dryer. Parker Freeze Dry works with pet food manufacturers at this stage regularly, and the same issues come up again and again: the equipment conversation starts too narrow, process variables get underestimated, and the infrastructure around the dryer gets overlooked until it becomes the bottleneck.
Below are the equipment, process, and facility questions we see manufacturers work through most often, and where better planning tends to make the biggest difference.
Why isn’t chamber capacity the same as production capacity?
Chamber capacity is the number most buyers start with. A freeze dryer rated for 2,500 lbs of wet product per batch, like the Parker 10 or Parker 10R, tells you how much raw material fits in the chamber. It doesn’t tell you how much finished product you’ll produce per day, week, or month.
Throughput is the number that matters for production planning, and it depends on several variables:
- How long the drying cycle takes for your specific product
- How consistently pans are loaded to the same weight and thickness
- How quickly the chamber turns between cycles
- How refrigeration and condenser systems perform under sustained daily operation
Here’s a simple illustration. Two operations run the same 2,500 lb chamber. One runs a 14-hour cycle at 30% finished yield. The other runs an 18-hour cycle at 25% yield. Before turnaround time is even counted, the first produces about 1,290 lbs of finished product per day and the second about 830 lbs. Same machine, roughly 50% difference in output.
The math is simple once you have real cycle data for your product. The problem is that many manufacturers start the scaling conversation with estimated cycle times and assumed yields, and the gap between projected and actual throughput can be significant. Equipment decisions based on chamber size alone often leave manufacturers short of their targets once they’re running real product, real loads, and real schedules.
What equipment decisions determine whether freeze drying can scale?
The freeze dryer is the centerpiece, but it’s one part of a production system. How the chamber, condenser, refrigeration, vacuum, and controls work together determines whether the operation can scale.
Condenser capacity. The condenser captures the moisture removed from the product. If it’s undersized for the product load and cycle parameters, it limits how much product can be dried per cycle and how many cycles can run back to back before defrosting. When comparing equipment, ask for ice condenser capacity relative to wet load. For reference, the Parker 10R lists 9,596 lbs of ice condenser capacity for a 2,500 lb wet load.
Refrigeration architecture. One freeze dryer at pilot volume places modest demands on refrigeration. Multiple chambers on staggered schedules need a system designed for sustained, variable load. Parker’s approach for multi-chamber facilities uses a shared refrigeration rack instead of pairing one compressor with each chamber. In one configuration, nine compressors serve five chambers and cycle on as needed. That setup can reduce energy waste and shorten defrost, because one chamber can be defrosted using cold generated for the others.
Vacuum performance. Deep, consistent vacuum is what allows sublimation to happen at low product temperatures, which helps preserve product structure. At production scale, the vacuum system has to hold that performance cycle after cycle. The Parker 10R, for example, adds a secondary booster pump for deeper, more consistent vacuum and is rated to 0.01 mbar or lower.
Controls and data. At production scale, operators need to develop, store, and repeat cycle recipes across products and shifts. They also need visibility into what’s happening across every chamber. Parker KPI lets Parker equipment owners monitor all chambers on site with one login, receive real-time alerts by text or email, track uptime and downtime, schedule maintenance, and pull run reports with historical data, including product temperatures at specific points in a run.
What process constraints limit throughput?
Even with the right equipment, process variables can cap how much finished product a facility produces.
Cycle time. Freeze drying is a batch process. The door closes, the air comes out, and the cycle runs as long as the product needs. Unlike extrusion, you can’t run the line faster. Cycle time is set by the product: moisture content, piece size, density, and the properties of the raw material.
Different pet food products dry differently. Whole muscle proteins, organ meats, formulated blends, and slurries each have their own drying profile. A single-ingredient chicken breast treat won’t dry on the same schedule as a complete meal with mixed proteins and vegetables. Manufacturers running multiple SKUs need a cycle recipe for each product, validated at production-scale loads, not assumed to carry over from pilot results.
Pan loading consistency. When product is loaded unevenly or pan weights vary from batch to batch, drying becomes inconsistent. Some pans finish early. Some product over-dries at the edges and under-dries in the center. That shows up in moisture readings, texture, and finished weight. Standardizing pan weight, piece size, and distribution removes a major source of variability. At higher volumes, automating loading, weighing, and cart handling reduces it further and lowers labor demand.
Turnaround time. Unloading, cleaning, reloading, and restarting is time the chamber isn’t drying. Facilities that plan schedules around turnaround, not just cycle time, often find meaningful throughput gains.
Why don’t pilot results always transfer to production?
Many pet food brands develop freeze-dried products on pilot-scale or tabletop equipment. That phase matters. But pilot conditions are different from production conditions.
Pilot runs are built for learning. Operators can adjust freely, small batches limit the cost of mistakes, and the goal is understanding how the product behaves. Production demands repeatability across larger loads, multiple batches, different operators, and continuous shifts.
A product that dried well in a 50 lb pilot batch may behave differently at 500 lbs or 2,500 lbs. Cycle parameters often need refinement, loading strategies may change, and condenser and refrigeration demands increase. That gap is normal. It doesn’t mean the product failed.
The most practical way to close it is to run the product on production-scale equipment before committing. Parker test runs on production systems show how the product performs at realistic volumes, what adjustments may be needed, and what throughput is realistic. A successful test run shows the product can be freeze dried at that scale. Commercial production still depends on equipment sizing, cycle development, facility layout, staffing, and your food safety program.
What infrastructure beyond the freeze dryer limits scaling?
Scaling conversations tend to focus on the dryer. The facility often becomes the real constraint.
Jerad Ducklow, executive vice president of sales and marketing at Parker Freeze Dry, has made the point in industry discussions that scaling is “not only an investment in the dryer.” Getting production running can also mean leasing a facility, buying additional equipment, and hiring people.
Electrical. Commercial freeze dryers and refrigeration draw significant power. The Parker 10R, for example, requires 480V three-phase power with a typical maximum draw of 215 FLA. Facilities need electrical service that supports continuous operation, especially with multiple chambers.
Floor space. The dryer and refrigeration skid take up substantial space, but so does everything around them: frozen raw material storage, dicing and prep, pan loading, cart staging, finished product handling, and packaging. Manufacturers who plan around the dryer footprint alone often outgrow their space quickly.
Water and wastewater. Defrost cycles, pan washing, and sanitation all add water demand. At commercial volume, washing thousands of pans a day requires dedicated equipment and drainage.
Staffing. Freeze drying can run around the clock, and many facilities run two or three shifts. The labor plan for loading, unloading, changeover, and maintenance decides whether equipment capacity turns into actual output.
Food safety and documentation. Freeze drying removes moisture. On its own, it isn’t a pathogen kill step. Pathogen control comes from ingredient sourcing, validated upstream steps, and your food safety plan. What freeze-drying equipment contributes is consistency: repeatable cycles, cleanable equipment, and run records that support your quality program.
How can freeze drying fit into a near-continuous production model?
Freeze drying is a batch process, but manufacturers who need high daily volume can build a steady production flow. The approach Parker uses with pet food manufacturers combines three elements:
- Staggered scheduling. Start times across multiple chambers are offset so one is always finishing while others are mid-cycle. Each chamber runs a discrete batch, but finished product comes out steadily.
- Automation of pre- and post-dryer tasks. Pan loading, cart handling, and weight standardization are where inconsistency creeps in, so they’re the first steps worth automating.
- Shared refrigeration. A multi-compressor rack serving several chambers spreads the load and supports faster defrost.
Matt Graunke, freeze dry sales executive at Parker Freeze Dry, walked through this framework in PetfoodIndustry using a facility that needed 7,000 lbs of finished product per day. Working backward from batch times and yield per pan showed that eight chambers on a staggered schedule could hit that target. “Once it’s set up correctly, it actually becomes stable and predictable,” Graunke said.
Discipline matters once the model is running. Graunke has pointed out that adding just one extra pound per pan, run across a full year of batches, can work out to roughly six extra hours per batch. Small deviations cascade through the schedule.
Where the market is heading
MarketsandMarkets forecasts the global freeze-dried pet food market will grow from $16.77 billion in 2026 to $26.77 billion by 2031, a 9.8% compound annual growth rate. Closer to home, an eTailPet survey of 189 U.S. independent pet retailers, reported by PetfoodIndustry in October 2026, found freeze-dried sales up 46% year over year.
For pet food manufacturers planning their next step, the question isn’t whether freeze drying can scale. It’s whether the full system (equipment, process design, facility, and operating model) is built to deliver consistent results at the volume your market demands.
If you’re planning to scale freeze-dried pet food production, a production-scale test run is a practical place to start. It gives you real cycle and yield data for your product, so equipment and facility decisions are based on numbers, not estimates.
