Overview
The QS-FD-20 is the pilot-scale model in the QS-FD freeze dryer family. Trays are loaded through the front door — wet and dry products kept separate — and freezing takes place inside the chamber, so no separate pre-freezing room is needed.
Under vacuum, ice sublimates from the frozen product at a −60 °C cold trap during primary drying. Four-zone heating then removes bound moisture, controlled to ±0.1 °C up to a maximum of 80 °C. The chamber is SUS304 stainless steel with food-grade silicone seals, and vacuum is held by Roots + screw vacuum pumps.
The control system is a Siemens S7-200 PLC with a Chinese/English touchscreen. Installed power is 35 kW, with actual power draw of about 60% of installed power.
