Industrial freeze dryers
In short
An industrial freeze dryer removes water from frozen food by sublimation under deep vacuum. Our QS-FD series comes in three chamber sizes — 20, 100 and 200 m² of shelf area — each in Standard, Advanced and Premium configurations, all in SUS304 stainless steel.
Model comparison
| Model | Shelf area | Wet load / batch | Footprint (L × W × H) | Best for |
|---|---|---|---|---|
| QS-FD-20 | ≈ 20 m² | 200–300 kg | 4500 × 1300 × 1400 mm | Pilot-to-small production |
| QS-FD-100 | ≈ 100 m² | 1,000–1,500 kg | 7000 × 4000 × 2300 mm | Mid-scale production |
| QS-FD-200 | ≈ 200 m² | 2,000–3,000 kg | 12000 × 4000 × 2300 mm | Large-scale production |

How to choose a freeze dryer
Start from your daily prepared wet input, divide by a realistic loading density (around 10 kg/m² for sliced fruit) and by the number of batches per day (usually one). The result is the shelf area you need. Then choose a configuration: Standard for cost-efficient fruit and vegetable production, Advanced for multi-product plants, Premium for coffee, dairy and export-grade products that need traceability.

FAQ
Freeze Dryers questions
What is an industrial freeze dryer?
An industrial freeze dryer (lyophilizer) freezes food and then removes the ice by sublimation under deep vacuum. The result is a light, crisp product with 2–5 % residual moisture that keeps its shape, colour and nutrients.
Which freeze dryer model should I choose?
Choose by shelf area: QS-FD-20 (≈ 20 m², 200–300 kg wet per batch) for start-ups and pilot runs, QS-FD-100 (≈ 100 m², 1–1.5 t) for mid-scale plants, and QS-FD-200 (≈ 200 m², 2–3 t) for large plants.
How long is a freeze-drying cycle?
Most fruit and vegetable cycles take 16–24 hours. Coffee extract and thick products can take longer; freeze-dried candy is much shorter.
What do Standard, Advanced and Premium mean?
They are control and refrigeration tiers on the same chamber: Standard (≤ −40 °C trap), Advanced (≤ −45 °C, recipe storage, remote monitoring) and Premium (≤ −55 °C, data logging, auto defrost).
