U.S.-Engineered Commercial Freeze Drying Systems
Commercial Freeze Dryers Built to Lower the Cost of Every Pound of Water Removed
Sublidyne engineers commercial and industrial freeze drying systems around one number: what it costs your operation to remove a pound of water. Every system is sized from your product's water load, not from a catalog.

Cost Per Pound
The number that runs a freeze drying operation
Most freeze dryer sellers lead with shelf area, model numbers, and pounds per batch. None of those tell you what a system costs to run. The figure that decides whether a freeze drying line makes money is the cost to remove one pound of water — batch after batch, year after year.
Two systems with identical shelf area can differ substantially in operating cost, because condenser capacity, refrigeration load, and vacuum performance determine how much water actually leaves per cycle and how much energy and time it takes. We design around that number.
We do not sell freeze dryers. We sell a lower cost for every pound of water removed.
Sizing Sequence
How a system gets sized, in five steps
Sizing runs in one direction: from your product to the machine. Reversing it — starting from a model number and hoping your product fits — is how operations end up with equipment that holds the batch but throttles the throughput.
02
Set the batch weight
How many wet pounds go in per cycle. This is the number that most strongly suggests a size class.
03
Calculate the water load
Solids equal batch weight times one minus starting moisture. Finished weight equals solids divided by one minus final moisture. Water removed is the difference.
04
Derive the removal rate
Water removed divided by target cycle hours. This is the rate the system must sustain continuously, not as a peak.
05
Match the machinery to that rate
Condenser, refrigeration, and vacuum sized together against the removal rate. Shelf area is an output of this step, never the starting point.
The Line
The SUBLON line: two thermal architectures
Products give up their water differently. Some transfer heat well through contact with a shelf; others need radiant energy because the shelf cannot serve them. Sublidyne builds both architectures across thirteen systems.
The numbers below are model designations. No capacity, throughput, or cycle-time figure is published anywhere on this site, because those figures are meaningless without your product and your loading practice attached to them.

Who We Build For
Who we build for
A high-fat raw pet treat, a heat-sensitive botanical extract, and a high-moisture fruit do not dry the same way. Each system is engineered around the realities of the product it will run.
01
Food
Fruit, vegetables, prepared meals, dairy, candy, and ingredients — sized to your moisture load and your finished-moisture spec.
02
Pet food
Raw treats, toppers, and complete diets, engineered for high-fat, high-protein products that load the condenser hard.
03
Nutraceutical
Supplements, botanicals, and extracts, where low-temperature water removal protects what the buyer is paying for.
04
Industrial
Plant-scale water removal and multi-unit lines for high-volume processing operations.

§ Q&A / Buyer Questions
Questions buyers ask before they call
Last reviewed August 22, 2026 · Sublidyne Engineering
What size freeze dryer should I get?
Start from the pounds of water one batch must remove, not the machine's advertised capacity. Take your batch weight, subtract the finished dry weight, and you have the water load. Divide that by your target cycle hours to get the removal rate the system has to sustain.
How do freeze dryers work?
Product is frozen solid, then held under deep vacuum while heat is applied. Under those conditions ice turns straight to vapor without melting, a change of state called sublimation. The vapor travels to a cold condenser, refreezes as ice, and is removed from the chamber.
What is a commercial freeze dryer?
A production-scale lyophilization system built to remove a defined water load per batch on a repeatable schedule. It differs from a home unit in condenser capacity, refrigeration, vacuum performance, controls, and the fact that it is engineered around a specific product rather than sold as a catalog size.
Is shelf area the right way to compare freeze dryers?
No. Shelf area tells you how much product you can lay down; it says nothing about how quickly the water leaves. Condenser capacity, refrigeration load, and vacuum performance set the removal rate. Two systems with identical shelf area can run very different cycle times.
Who makes commercial freeze dryers in the United States?
Sublidyne Systems engineers and builds commercial and industrial freeze drying equipment in the United States, based in Harrisonville, Missouri. Systems are engineered to order around each customer's product and water load rather than sold from a fixed catalog of capacities.
How much does a commercial freeze dryer cost?
Price follows the engineering, not a list. What drives it is the water load you need removed per cycle, the condenser and refrigeration capacity that load demands, chamber size, controls, and finish requirements. A quote that omits those inputs is quoting a box, not a system.
