Pilot Lab Freeze Dryer for Food Testing and Trial Production
Our pilot lab freeze dryer series includes SDG60 and SDG90 models for food product testing, process validation, and small trial production before commercial or industrial scale-up investment.
Compare wet material capacity, vacuum-down speed to 133 Pa, drying time, machine size, power, and shipping data before choosing SDG60, SDG90, or the next commercial or industrial category.
60–80 kg / 24h
For food testing, process validation, and smaller pilot runs.
90–120 kg / 24h
For larger food testing batches, trial production, and scale-up preparation.
Need More Than 120 kg Wet Material per 24h?
For 340 kg–1.36 tons / 24h, review commercial freeze dryers. For 1.2–8 tons / 24h and steam-supported factory production, review industrial freeze dryers.
Choose Between SDG60 and SDG90
Start from your wet raw material load. SDG60 is suitable for smaller testing batches, while SDG90 is better for larger pilot runs and pre-commercial trial production.
SDG60 Pilot Lab Freeze Dryer
For food product testing, process validation, and pilot runs when the daily wet material load is usually below 80 kg.
SDG90 Pilot Lab Freeze Dryer
For larger food testing batches, small trial production, and scale-up preparation before choosing a commercial freeze dryer.

Which Model Should You Choose?
Use SDG60 for smaller tests and SDG90 for larger trial production. If your daily wet material load is above pilot scale, review commercial freeze dryers for 340 kg–1.36 tons / 24h or industrial freeze dryers for 1.2–8 tons / 24h and steam-supported factory production.
Choose SDG60 If
- You are testing a new freeze-dried food product.
- Your daily wet material load is 60–80 kg.
- You need a compact pilot system before larger investment.
- Your site space or power condition is limited.
Choose SDG90 If
- Your product testing has already passed.
- You need 90–120 kg wet material capacity per 24h.
- You want trial production closer to commercial output.
- You plan to scale up after process validation.
Built for Real Food Freeze-Drying Tests
SDG60 and SDG90 use pilot lab freeze-drying design features that support repeatable testing, stable operation, and future scale-up.
Stainless Steel Chamber, Condenser & Frame
Stainless steel construction improves corrosion resistance during freezing, vapor capture, hot water defrosting, and repeated food testing.
High-Capacity Condenser / Vapor Trap
The condenser capture capacity is designed at ≥2 kg H2O/m²/h to support stable vapor capture during food freeze-drying.
Touchscreen HMI and Remote Monitoring
A touchscreen computer-based HMI supports real-time condenser temperature and pressure monitoring, data records, and mobile remote control and monitoring.
Uniform Radiation Heating
Radiation heating helps transfer heat more evenly across food trays during pilot freeze-drying tests.
Condenser Temperature & Pressure
The system monitors and records condenser temperature and pressure in real time for process review.
Touchscreen Computer HMI
The touchscreen computer-based HMI makes operation, parameter review, and test management easier.
Mobile Remote Control
Mobile remote control and monitoring help operators check equipment status without staying beside the machine.
Test the Product Before Buying a Larger Freeze Dryer
Food freeze-drying results depend on raw material moisture, slice thickness, loading density, target final moisture, and drying profile. A pilot test helps confirm color, shape, texture, drying time, and final product quality.
SDG60 and SDG90 help food manufacturers build practical production data before choosing SDG350 / SDG700 / SDG1100 commercial models or SDG1600 / SDG3000 / SDG6000 industrial systems.
Coffee-extract trials need product-specific solids, loading and water-removal calculations; see the coffee freeze-drying process guide.

Short answers for buyers who need to choose between SDG60, SDG90, or a larger freeze dryer.
What is the difference between SDG60 and SDG90?
SDG60 handles 60–80 kg wet material per 24 hours, while SDG90 handles 90–120 kg wet material per 24 hours. SDG90 is also larger, heavier, and has higher total power.
Does 60–120 kg mean dried product weight?
No. It means wet fresh material before freeze-drying. Final dried product weight depends on the moisture content of the raw material.
Can SDG60 and SDG90 be used for commercial production?
They can be used for small trial production, but they are mainly designed for product testing, process validation, and pilot production. For 340 kg–1.36 tons wet material per 24 hours, buyers should review commercial freeze dryers. For 1.2–8 tons per 24 hours with steam-supported factory production, buyers should review industrial freeze dryers.
What product thickness is recommended?
For many food products, a raw material thickness below 20 mm is recommended. The exact thickness depends on product type, moisture content, structure, and target drying time.
How long does drying take?
Typical drying time is 8–15 hours. Actual time depends on product type, thickness, loading density, freezing condition, vacuum level, and target final moisture.
Can the power supply be customized?
Yes. The default power supply is 3P 380V / 50Hz, but it can be customized according to the customer’s project requirements.
