What Are The Advantages Of Vegetable Drying Machine

In addition, Freeze Dry Machine is very suitable for processing biological products, such as blood, etc.,

Drying is a very old operation, but the heating and drying of powders and biological products often results in irrecoverable agglomeration of particles. Especially in the preparation of ultrafine powders, nanoparticles in the liquid phase are agglomerated into hard-to-disperse agglomerates after drying. This is mainly because in the ordinary drying process of particles, moisture is emitted from the pores between the particles, and the surface tension results in extremely high additional pressure, which compactly presses the particles together into agglomerates.  Freeze-drying of Vegetable Drying Machine can avoid this problem. Freeze-drying is to freeze the gel or blood to be dried into a solid, and then vaporize the water in the gel or blood under reasonable conditions to remove the water. Since the vaporization process of ice will not affect the coalescence state of solid particles, the original particles can be preserved intact without being compacted and agglomerated. In addition, Freeze Dry Machine is very suitable for processing biological products, such as blood, etc., because it has no high-temperature operation and can prevent deterioration of biological products.  However, the freeze-drying process is very slow and costly.  Freeze dryers are generally used in the pharmaceutical industry. They can be stored for a long time without changing physical properties. If the temperature is not well controlled by thermal drying, the physical properties of materials will be changed. This is the advantage of freeze dryers.
