Need Steam-Supported Industrial Production?
Review industrial freeze dryer models for 1.2–8 tons wet material per 24h, steam-supported operation, larger site space, and factory-scale installation planning.
When Should You Choose a Commercial Freeze Dryer?
A commercial freeze dryer is suitable when your product formula, slice thickness, loading density and drying result have already been tested, and you now need stable daily production instead of small pilot batches.
- Freeze-dried fruit and vegetable manufacturers
- Freeze-dried pet food producers
- Seafood, meat and prepared food processors
- Food companies moving from SDG60 / SDG90 pilot testing to commercial sales
Positioned Between Pilot Testing and Industrial Production
This page is designed for buyers who need 340 kg–1.36 tons of wet material handling capacity per 24 hours.
- For 60–120 kg / 24h testing, choose a pilot lab freeze dryer.
- For 340 kg–1.36 tons / 24h, choose a commercial freeze dryer.
- For 1.2–8 tons / 24h with steam-supported factory planning, review industrial freeze dryers.
Commercial Freeze Dry Machine vs Small Freeze Dryer
A commercial freeze dry machine is not simply a larger home freeze dryer. For food production, buyers should compare wet material capacity, water removal load, condenser performance, vacuum stability, energy consumption and operator support.
Why Small Freeze Dryers Are Usually Not Enough for Production
Small freeze dryers may support product testing, recipe development or early samples. However, commercial food production needs repeatable batch results, stronger refrigeration, larger condenser capacity and better loading efficiency.
How to Judge a Commercial Freeze Dry Machine
Buyers should review the real daily wet material capacity, drying time, final moisture target, power supply, site space, defrosting method and after-sales training before choosing a machine.
Choose Your Commercial Freeze Dryer by Daily Wet Material Capacity
Start with your daily wet material load. SDG350 is suitable for smaller commercial production, SDG700 is suitable for medium commercial output, and SDG1100 is suitable for higher commercial production before moving to steam-supported industrial scale.
SDG350 Commercial Freeze Dryer
For commercial food producers who need stable daily production but do not yet need a large factory-scale freeze-drying line.
SDG700 Commercial Freeze Dryer
For food manufacturers who need higher daily output and more stable batch production for commercial sales.
SDG1100 Commercial Freeze Dryer
For larger commercial food production projects that need more than one ton of wet material handling capacity per 24 hours.
