Freeze-Dried Radish Case Study
This freeze-dried radish case study shows how an Indian food processor used an SDG60 3㎡ freeze dryer to process approximately 39.6 kg of radish slices per batch and complete drying in 12 hours.
Quick Facts
This radish slice project used real production data instead of general marketing claims. The data helps vegetable processors evaluate batch capacity, drying time, vacuum range, cold trap capacity, final moisture, and energy cost.

Small Commercial Freeze-Dried Radish Production
In 2022, a food processing customer in India used an SDG60 3㎡ commercial freeze dryer to produce freeze-dried radish slices for vegetable processing.
Radish slices have a firmer vegetable structure than many soft fruits. Therefore, the drying process needs stable heat input, vacuum control, and reliable moisture removal to reach a low final moisture content.
For this project, radish slices were loaded at 13.2 kg per square meter. With a total drying area of 3㎡, the batch loading capacity reached approximately 39.6 kg per batch.
This calculation helps buyers understand real production capacity. Drying area alone is not enough; loading density and drying time must be evaluated together.
The Challenge: Drying Radish Slices Consistently
Radish slices must be dried evenly from the surface to the center. Stable vacuum control and suitable cold trap capacity help reduce uneven moisture risk.
Firm Vegetable Structure
Radish slices need controlled heat input to support moisture movement from inside the slice.
Small Batch Production
The 3㎡ system matched product testing and small commercial vegetable production needs.
Low Final Moisture
The final moisture content reached 2.09%, supporting storage stability and packaging.
Vacuum Stability
The drying process operated within a 26–86 Pa vacuum range.
Cold Trap Capacity
The condenser capacity was designed at 2 kg water/㎡/hour.
Energy Control
The energy consumption was approximately 1.89 kWh per kg of fresh radish slices.
SDG60 3㎡ Freeze Dryer
The SDG60 freeze dryer was selected to support small commercial vegetable production, product testing, stable vacuum control, and predictable drying results.
- 3㎡ drying area for small commercial vegetable production
- 13.2 kg/㎡ radish slice loading density
- 26–86 Pa vacuum range during drying
- 2 kg water/㎡/hour condenser capture capacity
- 12-hour drying cycle with 2.09% final moisture
- 1.89 kWh/kg fresh material energy consumption
Real Drying Data for Freeze-Dried Radish
This section gives buyers practical reference data. It shows how loading density, vacuum control, cold trap capacity, final moisture, and energy use affect actual production performance.
In this project, the SDG60 processed about 39.6 kg of radish slices per batch. The drying cycle was completed in 12 hours, and the final moisture content reached 2.09%.
| Product | Radish slices |
|---|---|
| Fresh Material Loading | 13.2 kg/㎡ |
| Total Batch Load | Approx. 39.6 kg/batch |
| Vacuum Range | 26–86 Pa |
| Condenser Capacity | 2 kg water/㎡/hour |
| Total Condenser Capacity | Approx. 6 kg water/hour |
| Final Moisture | 2.09% |
| Energy Consumption | 1.89 kWh/kg fresh material |
| Drying Time | 12 hours |
Production Result: 12-Hour Drying Cycle
The SDG60 3㎡ freeze dryer completed the radish slice drying process in approximately 12 hours. The final moisture content reached 2.09%.
Why These Data Points Matter
For vegetable processors, real production data is more useful than general machine descriptions. These parameters help estimate output, freeze dryer cost, and equipment suitability.
1. Loading Density
The customer loaded radish slices at 13.2 kg/㎡. For a 3㎡ freeze dryer, this means approximately 39.6 kg per batch. This gives buyers a clearer way to estimate production capacity.
2. Cold Trap Capacity
The condenser capacity was 2 kg water/㎡/hour. Based on a 3㎡ drying area, the maximum condenser capture capacity reached approximately 6 kg water/hour during high-load drying stages.
3. Energy Consumption
The energy consumption was approximately 1.89 kWh per kg of fresh material. Based on 39.6 kg per batch, the estimated electricity use was about 74.84 kWh per batch.
What Vegetable Processors Can Learn from This Case
This India freeze-dried radish project shows that vegetable freeze-drying equipment should be evaluated by real drying performance, not only by machine size or price.
Product Form Matters
Radish slices dry differently from fruit, cooked rice, or mixed meals. Slice thickness and loading density should be tested.
Ask for Real Drying Data
Batch load, drying time, final moisture, vacuum range, condenser capacity, and energy use provide more value than general supplier claims.
Check Energy Consumption
Energy use affects the real production cost. In this case, the energy consumption was 1.89 kWh per kg of fresh radish slices.
Match Machine Size to Production Stage
A 3㎡ freeze dryer can be a practical choice for testing and small commercial vegetable production before scaling to larger systems.
