DYYB-18S freeze-drying machine is a small vertical freeze-drying equipment, freeze-dried samples for laboratory testing and small production, the models have programmable control of heating shelf freeze dryer LGJ series, the use of PID regulation precise temperature control, human-computer interface using a large-screen LCD screen, the way the curve and data while providing the user more information about freeze-drying process, and with a host computer communication interface. 
 This series is divided into: common type freeze dryer, gland-type, multi-manifold common type, multi-manifold type gland, in situ freeze-drying machine. 
 Freeze Dryer Features: 
 ① LCD: separator temperature curve, cold trap temperature curve, the sample temperature curve; 
 ② can store 32 programs, each program can be set 36, freeze-drying machine in the process of running program parameters can be modified, and the memory of the final drying curve; 
 ③ freeze-drying machine touch screen display of the function keys, no operation buttons, reducing misuse and improve the reliability and stability of the instrument; 
 ④ circuit system uses PID control to more precise control precision; 
 ⑤ freeze-drying machine imported compressor, compound refrigerant, cooling speed, drying effect;
