Introduction
The Vekuma FD-20R commercial food freeze drying equipment was designed for medium scale factory. It has 19.44m2 shelf area that enable for product loading, coupling with a 200kgs/24hrs vapor collect condenser.
Its all-in-one structure, all the machinery that involved with the operation of it is mounted behind the drying chamber in a steel frame. Ice condensing coils can be installed in rear side of drying chamber or beneath shelves.

Design Features
High advanced PLC and user-friendly touch screen HMI is applied to all our FDR freeze dryers, to control machine functions, performs all interlock checks, and generates processes and device alarms. Capable of automatic execute the freeze drying steps you are programmed, monitoring system running status and protect your freeze dry system all the time.
The control system has been pre-programmed a bunch of protection logic such as: System auto shut down if chamber pressure not reduce; Vacuum pump will not active if condenser temperature not reach set to avoid vapor flows into vacuum pump and damage it; Once an failure appears, sound-light alarm and touch screen HMI shows possible failure reason, meanwhile, all air and water isolate valves auto close to maintain chamber pressure and protect your products.
The delicate designed FD-MEGA V2.0 guarantees your drying data and drying steps that stored in HMI will not lose once a power outage, and the drying process will continue after power restoration. As well as, it supports operator modify the current-running freeze drying steps (when machine is in operation), system will auto execute the latest modified drying recipe.
The FD-MEGA V2.0 enables you control all the key components On/Off , all the valves Open/Close through the touch screen, and a real-time monitoring of their status. Which means during whole freeze drying process, nobody is needed go to technical room to do manual works.
The FD-MEGA V2.0 has the functions of:
- Graphic display main components working status and key parameters.
- System and key parts functional test.
- Automatic and semi-automatic work mode.
- Freeze drying recipes management.
- Real-time freeze drying curve.
- Historical curve review.
- Drying data-logging and can be exported via USB.
- Users, password and authorizations.
- Sensors calibration.
