How to correctly select the latest drying equipment? Now there are many kinds of drying equipment, which are dazzling. So if we want to know how to correctly select the latest drying equipment, we must first know how the current drying equipment is classified, because now according to different criteria, there are many kinds of drying equipment.
The first classification is based on heat transfer methods. They are: (a) conduction heating; (b) convection heating; (c) radiation heating; (d) microwave and dielectric heating. Freeze drying does not belong to the above several, you can separate the freeze-drying, because it belongs to a special case. The second classification is based on the type of dry container, such as pallet, drum, fluidized bed, airflow or spray. Another one can be classified according to the physical shape of the raw materials.
If further subdivision, it can also be classified according to the drying time. For example, there are flash, spray and drum drying equipment within 1 minutes of residence time; tunnels, trolley or belt drying equipment with more than one hour residence time.
Now let's introduce how to choose drying equipment through the form of raw materials.
Belt type drying equipment: granule, fragile crystal, sheet material, fiber, molding object.
Flash drying equipment: centrifugal separation filter cake, filter cake, powder, particles, fiber.
Fluidized bed drying equipment: solution, paste, centrifugal separation filter cake, filter cake, powder, particle, sheet material.
Rotary drum drying equipment: centrifugal separation filter cake, filter cake, powder, particle, sheet material, fiber.
