Boiling dryer airflow distribution plate has two roles, first, support material layer, the second is to make gas distribution. Advice on improving air intake air: The air outlet of hot air is generally set in the auxiliary engine room, and the heating device and the silencer are installed together, and the auxiliary engine room and the clean area are not provided with direct windows and doors. Early replacement will increase costs, postpone the replacement will bring the risk of air quality degradation, thus affecting the quality of the product.

Boiling dryer airflow distribution plate has two roles, first, support material layer, the second is to make gas distribution. Distribution hole size, shape, distribution, opening rate and so on all play a crucial role in the distribution of fluids. Inhomogeneous gas distribution causes "circulation" in the bed, which tends to cause "ditch flow" in some parts of the bed at extreme extreme, while the rest is the dead bed where most of the gas follows the bed Some of the channels in the form of "ditch" short-circuit through the bed to make the gas-solid contact greatly deteriorated, which should be avoided. Good distribution board design, should be able to inhibit the bed inhomogeneity, that is, when some parts of the bed due to pressure drop decreases, the air flow rate increases, the distribution plate resistance should be able to inhibit the air flow increases, thus inhibiting Fluidized deterioration.

Advice on improving air intake:
The air outlet of hot air is generally set in the auxiliary engine room, and the heating device, muffler installed together, auxiliary engine room and clean area is not set through the doors and windows. Auxiliary engine room air cleanliness levels are often relatively low, will affect the quality of medicated hot air, which requires the device itself has a good purification device, or unpurified air will pollute the drugs, it is difficult to meet GMP requirements. At present, many domestic equipment on the air handling unit configuration: out of the filter, the filter efficiency, steam heating (or electric heating), high efficiency filter. Although the air handling system is equipped with primary, medium and high efficiency filters, with the continuous increase of running time, high efficiency filters will be clogged or damaged. At present, the appearance and appearance of the air filters can not be changed without a theoretical basis. Early replacement will increase costs, postpone the replacement will bring the risk of air quality degradation, thus affecting the quality of the product.
