What are the characteristics of boiling drying machine?

Boiling dryer is also called fluidized bed drying It uses hot air flow to make wet particles suspended, fluidized boiling to make materials carry out heat exchange, take away the evaporated water or organic solvent through hot air, and it uses hot air flow to carry out the mass and heat transfer mode of gas-solid two-phase suspension contact, so as to achieve the purpose of drying wet particles Fluidized bed drying technology involves two mutual processes of heat and mass transfer In the process of convective drying, the hot air transfers the heat energy to the surface of the material through contacting with the wet material, and then from the surface to the inside of the material, which is a heat transfer process; When the wet material is heated, the surface moisture is first gasified, and the internal moisture diffuses to the surface of the material in liquid or gas state, and continuously gasifies to the air, which gradually reduces the moisture content of the material and completes the drying, which is a mass transfer process The following is a brief introduction of the product features of the boiling dryer, as follows: 1 The equipment has a wider fluidization range, which can handle some particles that are too wet, sticky or have a wider particle size distribution, and the drying effect is significant 2 Closed negative pressure operation, gas filtration, good sealing The whole equipment is easy to operate, disassemble and clean It is an ideal equipment in line with GMP requirements 3 The boiling dryer adopts tipping and unloading, which is convenient, quick and complete It can also design the automatic feeding and discharging system according to the requirements 4 The fluidized bed is of circular structure to avoid dead angle 5 Fast drying speed and even temperature 6 The hopper is equipped with mixing to avoid the agglomeration of wet materials and the formation of ditch flow during drying Through the above content, I hope to help you understand the boiling dryer
