What Technologies Are Used In Lyophilization Equipment?

  • Today, gf-machine  Lyophilization equipment is more common in a variety of industries. If there is ice blockage in the freeze dryer, the cooling effect cannot be achieved. Let's analyze the following question:

    1. When the air pressure is pressed, the pressure enters. The air contains water, but the moisture contained in the humidity is different. If the temperature in the cabinet and the temperature of the evaporator are relatively high and dry, the moisture in the compressed air does not easily condense into water droplets, and when evacuated, the water vapor is discharged into the system together with the gas stream. If the temperature of the cabinet is very low, ie the temperature of the evaporator is very low, the water introduced by the pressure will form water droplets or form frost in the evaporator tube to adhere to the pipe. This cream does not excrete when it is evacuated. Simply remove all the ice cubes from the refrigerator, then use the baking method to raise the temperature of the evaporator so that the water droplets are inside the tube and the frost is evaporated and then emptied. It can also be handled by adding snow and then evacuating.

    2. Since the evaporator has a leak point, water is drawn from the leak point when the refrigeration compressor is operating, and moisture is still present in the pipe after the evaporator is repaired. In combination with the use of refrigerant, heat and bake off the evacuation treatment.

    3. Because the evaporator has a leak point, water is drawn from the leak point when the refrigeration compressor is operating. These water droplets are drawn into the refrigeration compressor because the water is heavier than the oil and the water droplets are frozen at the bottom of the refrigeration compressor. It is difficult to disappear at once, which is an important reason for stubborn stubborn ice. s View site solution is to let the refrigeration compressor run heat, so that the temperature of the refrigeration oil rises, the water gradually precipitates in the rotating coil of the rotor, the temperature rises, and is continuously extracted, plus the snow test machine, if there is ice block, repeat The above procedure until the ice cubes are removed.

    With the freeze-drying technique, the advantage of denaturation or loss of bioactivity of the drug can be largely prevented. It is believed that the future vacuum freeze-drying technology will be further developed, and the application field of freeze dryer will continue to expand. The freeze dryer will continue to meet the needs of various pharmaceutical, bio-health products, freeze-dried foods and solid micropowder preparation.
