Digital demonstration Curve freezing and drying 
LGJ30/50 Medium-sized freeze-dryer
| Freeze-drying machine is to freeze the water-bearing materials in advance, and then the water in the vacuum distillation of dry goods and access to a technical approach. After freeze-drying the items easier to deal with long-term preservation, water could freeze-dried back to the pre-state and maintain the original chemical and biological characteristics. For the thermal material, such as antibiotics, vaccines, blood products, hormones and other bio-products, freeze-drying technology can show its superiority. LGJ-30/50-frozen areas of 0.3M2, 0.5M2, double-barrel structure of the pre-freeze in situ. It changed the course of the last dry red tape operation to prevent the pollution of the material and realized the dry distillation of automation. Apply to the pilot or small batch production. With heating shelf programmable control LGJ series of freeze-drying machine, using PID regulation, accurate temperature control, human-computer interface using large-screen LCD, and the curve to data, made available to users at the same time freeze-drying process more Information and communication with a PC interface. Characteristics ¡ñAdd to dry the interior materials, in situ and pre-freeze-drying, freeze-drying process to achieve automation ¡ñTouch-screen liquid crystal display, PID intelligent adjustments in order to curve and data, made available to users more information about the process of drying; ¡ñImports of used compressors, condensing coil low temperature, increased ability to catch the water, to extend the service life of vacuum pumps; ¡ñTwo dry room to operate at the same time, can also be a separate operation to facilitate the needs of users ¡ñOptional charge or inert nitrogen gas filling valve; ¡ñCommunication with optional USB interface on the computer or print directly observe the freeze-drying curve. |
