Development trend of colloid mill
These models can describe the process of colloid mill, but there are some shortcomings, describe the heat transfer process is more accurate, describe the mass transfer process error.
From recent years of research reports have not seen a new breakthrough.
The structural size of the porous channel is also related to the pre-freezing speed, the material structure of the colloid mill.
The main problem is that the phase transition of the solid-vapor phase occurs during the mass transfer process. The water vapor is transferred in the porous channel. The length of the channel changes with time and is the unsteady process.
