Overview
What is the QS-FD-20 Compact Industrial Freeze Dryer?
The QS-FD-20 Compact Industrial Freeze Dryer is a QS-FD-20 industrial vacuum freeze dryer (lyophilizer) with ≈ 20 m² of shelf area, handling about 200–300 kg of prepared wet product per batch. It is used for fruit, vegetables, freeze-dried candy, pet treats, herbs and chili, and comes in Standard, Advanced and Premium configurations with cold traps from −40 °C down to −55 °C. Typical food cycles run 16–24 hours to 2–5 % residual moisture.
Sublimation under deep vacuum
Ice turns straight to vapour, so products keep shape, colour, aroma and nutrients.
Cold trap down to −55 °C
Captures water vapour fast and protects the vacuum pumps, keeping chamber pressure stable.
SUS304 hygienic build
Food-contact chamber, shelves and trays in polished stainless steel, easy to wash down.
Three configurations
Standard, Advanced or Premium refrigeration and controls on the same proven chamber.
Even shelf heating
Circulating thermal fluid keeps shelf temperature uniform for consistent batches.
Factory acceptance by video
Every machine is run and filmed before shipment so you see it working first.

Process
How it works
- Freeze — product on trays is frozen to about −35 to −40 °C.
- Primary drying — vacuum is pulled to 10–60 Pa and gentle shelf heat sublimates the ice; vapour freezes on the cold trap.
- Secondary drying — shelves warm further to remove bound water down to 2–5 % moisture.
FAQ
Questions about this machine
What is the capacity of the QS-FD-20 freeze dryer?
The QS-FD-20 has ≈ 20 m² of shelf area and takes about 200–300 kg of prepared wet product per batch at a typical fruit loading density of around 10 kg/m². One batch normally runs 16–24 hours.
What is the difference between Standard, Advanced and Premium?
They share the same chamber. Standard (≤ −40 °C cold trap) is the cost-efficient core build; Advanced (≤ −45 °C) adds recipe storage and remote monitoring; Premium (≤ −55 °C) adds batch data logging, automatic defrost and remote diagnostics.
Which products can the QS-FD-20 dry?
Typical uses are fruit, vegetables, freeze-dried candy, pet treats, herbs and chili. The same machine also handles meat, seafood, dairy and ready meals; cycle time and loading density change by product, so we recommend a sample test run.
What utilities does the freeze dryer need?
A 380 V three-phase supply (220 V and other voltages on request), cooling for the refrigeration system (air-cooled or water-cooled with a cooling tower) and around 1.5 m of service clearance.
How is the machine inspected before shipping?
Each unit is assembled, vacuum- and temperature-tested and filmed in operation. You receive the inspection video before shipment.
