The laboratory freeze-drying machine equipment series has a normal temperature of -50 °C for most materials, as well as special materials, low crystallization point, high requirements -80 degrees low temperature type, the device can be selected as ordinary type, gland type, Multi-manifold type, in-situ type.
The following is the design structure of the laboratory freeze dryer equipment, the overall structure is compact and reasonable, small size and flexibility! It mainly consists of a housing, a refrigeration unit, a vacuum pump, and a cold trap. The refrigeration unit is disposed in the casing; the cold trap is disposed at the upper portion of the casing; the vacuum pump is connected to the cold trap through the vacuum pipe; the refrigeration unit has a compressor, a heat exchanger, an expansion valve, and an evaporator; and the material placement device and the material placement device are installed. Above the cold trap and on the housing, and in communication with the upper end of the cold trap; the evaporator is an evaporating coil disposed within the cold trap. The evaporator is changed to an evaporation coil, and is set in the cold trap, and the cooling speed is fast.
