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.

## 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).
