Industrial food freeze dryers are batch production systems that remove water by freezing the product and then sublimating the ice under vacuum. HADOF sizes them from the material, the daily-output target and the water-removal duty — not from a nominal batch weight alone. They serve food processors who need documented shelf-life, shape and nutrient retention at production scale.
Who this is for
Where it is used
- Fruit and vegetables — whole, sliced or diced product where piece shape and color matter.
- Meat, seafood and prepared meals — high-protein or high-moisture material that needs a defined freezing and drying curve.
- Dairy, soups and extracts — liquids and concentrates that must dry to a stable powder or cake.
- Pet food and ingredients — batch repeatability across daily production.
The relevant question is not “can it dry many things” but which cycle each material needs. Every material has its own freezing point, initial moisture, piece geometry and target residual moisture — these define the cycle, not the machine name.
Reference models and published parameters
The values below are published reference figures for the contact-heated, rear cold-trap configuration. They identify the scale of each model; the final configuration is confirmed against the selected material and throughput.
| Model | Effective loading area | Loading volume | Standard feed | Freezing | Drying cycle |
|---|---|---|---|---|---|
| HDF-30 | 3 m² | 0.24 m³ / batch | 30 kg / batch | 4–6 h | 12–35 h |
| HDF-50 | 6 m² | 0.28 m³ / batch | 50 kg / batch | 4–6 h | 12–35 h |
| HDF-100 | 10 m² | 0.30 m³ / batch | 100 kg / batch | 4–6 h | 12–35 h |
| HDF-200 | 20 m² | 0.63 m³ / batch | 200 kg / batch | 12 h | 12–35 h |
Effective loading area by model
Standard feed per batch
Published reference values. Drying time depends on initial moisture, piece geometry and target residual moisture.
How to read these parameters
- Effective loading area sets the batch scale and the shelf space; it drives chamber size, footprint and utility demand.
- Standard feed per batch is the fresh-material reference — actual output depends on initial and target moisture.
- Freezing and drying time are ranges, not fixed values; a low-moisture material with thin fill can sit at the short end, a high-moisture thick fill at the long end.
- Loading volume affects tray depth, loading method and how much product fits before drying shrinks it.
How to choose a configuration
Standard configuration
For a single validated product with a defined batch and daily output. Lowest cost and shortest lead time; the cycle, shelves and condenser are matched to that material.
Extended configuration
For multiple products or a changing range. More shelf area, wider control range and recipe storage make changeovers faster and keep batch records consistent.
Customization scope
Chamber size, shelf count and heating method, condenser capacity, vacuum and refrigeration duty, control-system depth, material of construction and hygienic finishes are configured per order. Customization affects lead time and price, so it is confirmed with a material sample and a stated daily-output target before quotation.
Quality control
Packaging and shipping
Industrial dryers are packed in export-grade crates with moisture, shock and lifting protection. Provide the destination country, site access dimensions and preferred delivery window so the crate, container loading and shipping documents are matched to the route.
After-sales and maintenance
- Installation and operating documentation delivered with the machine.
- Commissioning or remote guidance available depending on configuration.
- Maintenance schedule, spare-part list and remote troubleshooting support.
- Warranty scope and its boundary conditions confirmed in the quotation.
How pricing works
Price is driven by effective loading area, refrigeration and vacuum configuration, control-system depth, hygienic options, customization and destination. A standard single-product configuration costs less and ships sooner; a multi-product or custom line adds engineering and documentation. Share the material and target output and we quote the configuration you actually need rather than a default model.
Frequently asked questions
Can I buy a single unit to start?
Yes. The HDF-30 is a practical entry point for a single validated product; you can size up as demand grows.
What do you need to recommend a model?
The material, starting and target moisture, fresh loading per batch, tray or container format, and the batches per day you need.
How long is the lead time?
It depends on whether the configuration is standard or custom, and on current production load. It is confirmed in the quotation.
Do you help with installation?
Yes — installation documentation is included, and commissioning or remote guidance is available by configuration.
