The FBD system is usually used for granulation, where high-quality powders are remodeled into granules with enhanced flowability, compressibility, and uniformity. The fluidized mattress facilitates the even distribution on the binder solution, resulting in uniform granule development.
The air velocity and temperature are important in this process to ensure the particles present inside the product mattress continue to be inside a suspended condition, thus achieving fluidization.
The air is filtered in the filter after which you can passes in the mattress of the fabric at the bottom.
Mechanisms for discharging the dried product or service through the fluidized mattress when the drying system is comprehensive.
From the pre-heating stage, the mattress’s temperature was mounting but With this stage, particles continue being in the exact same temperature. It is the situation because any Electricity supplied is taken up by the evaporating molecule as the transition on the liquid into the gaseous condition.
Mechanical shaking is The easiest way to eliminate the dust layer and it is done through the pneumatic cylinder for the established intervals and appears to be Now we have two filtering chamber the shaking is alternated between the two.
If air is allowed to stream via a mattress of sound powdered material in the upward way Along with the velocity better when compared to the settling amount from the particles, the sound particles will probably be blown up and become suspended within the air stream.
Very last Up to date on: May possibly 14, 2023 by Naresh Bhakar FBD refers to the Fluidized mattress dryer that is often Employed in the pharmaceutical sector to decrease the humidity articles of pharmaceutical granules.
In these dryers, the fluidized bed is subjected to vibrations, which assist in better Speak to involving the drying medium and the material. This increases warmth and mass transfer, leading to faster and more uniform drying.
This machine can have some major issues if It is far from handled in the right way. Here are some with the popular complications:
As the move of air will increase, the mattress expands and particles of powder start to stand up in a turbulent motion.
If the gasoline or air velocity is increased, it read more reaches a point the place the drag force exerted to the particles overcomes their weight, producing them to be suspended within the fluidized mattress.
SS filters are created of stainless steel and possess fantastic check here perforations which protect against happy loss and permit air to pass. Bag filters are made of canvas fabric.
Environmental air is processed by the processing unit, in processing unit air is filtered as a result of diverse filters. Firstly air pass-by way of coarse filters or perhaps the mesh filters also known as Most important filters. Following mesh filters air move-by means of secondary filters or bag filters.
