Food Freeze Dryers

Vekuma’s commercial and industrial scale freeze dryers are superior quality and well-known in China market for 2 decades. High-performing and solidly built, and with unbeatable features of constant freeze dried quality between batches due to its solid quality and designs to ensure uniform temperature.

We know that your freeze dryer has to be dependable to support the good running of your business, and it has to be energy saving, to reduce your production cost. Vekuma uses its knowledge in the field and produced high quality food lyophilizers that you can rely on, boost your business health growth.

High advanced PLC and user-friendly touch screen HMI is applied to all our FDR freeze dryers. To control all the 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 touch screen HMI 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 control interface has the functions of:

• Alive display main components working status and key parameters.
• Freeze drying recipes management system.
• Real-time freeze drying curve and history drying curve review.
• Drying data-logging and can export to USB memory.
• Automatic and semi-automatic work mode.
• Users and authorizations.
• Sensors calibration.

All FDR models are equipped with our FD-MEGA controller Ver 2.0. The HMI interface enables you control all the key components On/Off and valves Open/Close through the touch screen, and real-time monitoring their work status. Which means during whole freeze drying process, nobody is needed go to technical room to do manual works.

All valves that use to isolate air and water are pneumatically operated, which includes vacuum pump anti suck back valve, vacuum release valve, condenser & chamber isolation valve, condenser defrost water supply, overflow and drain valve.

FD-5R to FD-30R suits commercial small to medium capacity, batch loading 50kgs to 300kgs. These freeze dry systems come with all-include structure, ready to use deliver.

FD-30R to FD-200R are industrial large food freeze drying plants, capacity 300kgs to 2000kgs. These freeze dry systems are modular designed, deliver by pieces, on-site assemble for easy produce, transport and install.
