Four-ring freeze-drying freeze-drying machine is often used in experimental, scientific research, universities and other places, so it is also called experimental freeze-drying machine
.
A cold trap is one of the components of a freeze dryer, a device used to trap steam
.
Generally, the lower the temperature of the cold trap, the stronger the capture capacity of the cold trap, and the higher the relative machine cost
.
At present, the cold trap temperature of the experimental freeze dryer is mainly divided into three stages: -50°C, -60°C, and -80°C
.
Application of four-ring freeze-drying freeze-drying machine: 1.
Processing different materials: it can freeze-dry materials in freeze-drying type, and freeze-dry materials on hanging bottles.
Each hanging bottle can handle the same materials with different concentrations or Materials with different characteristics; 2.
Increase the freeze-drying area: attach a flask to the outside of the drying type, and dry the materials spun on the inner wall of the bottle.
At this time, the flask is connected to the manifold outside the drying box as a container, and the material can also be Put it in the bottle for freeze-drying; 3.
During the freeze-drying process, you can take out the hanging bottle at any time to observe the freeze-drying state: you can take off or install the flask at any time as needed, no need to stop, it is suitable for experimental research materials in different periods, drying characteristics, or teachers It is easy to take it out to teach students when teaching
.
Generally, different cold trap temperatures have different uses.
The four-ring freeze-drying freeze dryer with a cold trap temperature of -50°C is suitable for freeze-drying of water solvents or products with a solvent freezing point above -40°C.
The influence experiment shows that the temperature of the cold trap decreases from -35°C to -50°C, and the water-capturing capacity is improved significantly
.
Therefore, in the absence of special requirements, the temperature of the cold trap is -50°C
.
The four-ring freeze-drying freeze-drying machine with a cold trap temperature of about -80°C is suitable for the freeze-drying of most products such as products containing organic solvents or the freeze-drying of some special products
