The LMFD540H, LMFD840H, LMFD1040H and LMFD1540H Food Freeze Dryer series is designed for controlled vacuum freeze drying of food materials. The system removes moisture from frozen products through sublimation while supporting preservation of nutrients, flavor and appearance.
The models provide drying areas from 0.4 m² to 1.5 m², with 4 to 7 SS304 trays and a -40°C condenser temperature. A 7-inch touch screen provides operating control and monitoring, while the system supports graph viewing, password protection and multiple operating modes.
The system includes temperature control, vacuum operation, heating-coil defrosting and 10-recipe data memory. The transparent acrylic door allows visual monitoring of the drying process, while locking wheels facilitate movement and positioning.
