Introduction
Nowadays, fluid bed dryers are widely used in the food processing industries. The primary reason for such popularity is that these machines improve the quality of products and reduce the drying time. Moreover, this equipment operates hygienically and ensures excellent safety. It is not only beneficial to the environment but also increases cost-effectiveness by reducing energy consumption. VJ Instruments consists of various products ball mill machine in pharmaceutics, cone blender, morris water maze.
Fluid bed dryers are the equipment used in pharmaceutical industries for different applications such as mixing, drying, granulation etc.
Fluid bed dryer are the equipment used in pharmaceutical industries for different applications such as mixing, drying, granulation etc. The fluidized air is used to provide an effective method of drying.
Everything about Fluid Bed Dryer can be explained by dividing them into a fluidized bed and a drying chamber.
The main part of a fluid bed dryer is the drying chamber. This is the box where you put your product, and it’s what helps keep everything moving. The walls of this chamber are made up of perforated trays that hold a certain amount of drying medium.
The second part of a fluid bed dryer is called the fluidized bed. This is where most of your action happens: all those little holes in those perforated trays allow air to flow through them, and when heated, these air currents lift all your granules or powdery bits so they can get evenly exposed to heat from above (from infrared lamps or microwaves).
The fluidized bed is mounted on top of the drying chamber.
The fluidized bed is mounted on top of the drying chamber. It consists of two concentric cylinders. The inner cylinder has a series of holes in it and the outer one is made up of perforated plates. A high-velocity air stream blows through these holes and carries with it all powders as well as gases produced by the heating process, thus causing them to rise into a fluidized state.
The powder mixture enters from below into this fluidized-bed where it gets evenly distributed over its entire surface area due to turbulence caused by high-velocity airflow. This ensures even drying of all ingredients present within the mixture since there are no dead spaces left behind at any point during the drying process which could prove detrimental to quality in case they were not exposed to the sufficient amount of heat required for complete chemical transformation (if any).
The fluid bed has an air inlet to provide the air and a pre-filter to remove the dust particles from the air.
The fluid bed has an air inlet to provide the air and a pre-filter to remove the dust particles from the air. The pre-filter is very important because it helps prevent product damage caused by foreign particles entering the drying chamber. The main purposes of this type of dryer are mixing, heating, and cooling processes. It is used mainly for drying all kinds of granular products like grain, feedstuff and pellets etc.; also it can be used for liquids such as paints etc., which are commonly applied by spray guns on various substrates (e.g., coils).
The air first enters the drying chamber and then via a perforated plate or baffles into the fluidized bed.
Air enters the drying chamber and then via a perforated plate or baffles into the fluidized bed. The air will rise through the bed, distributing itself evenly in all parts of it. In this way, there is no preferential deposition of material at any point on top of the fluidized bed, thus ensuring that all constituent particles are mixed well.
Air is forced through the product layer with enough energy to support it in a fluidized state.
Air is forced through the product layer with enough energy to support it in a fluidized state. This means that there are enough particles of air moving around the product to keep it “fluid” and not allow static electricity to build upon the product’s surface. Static electricity can cause problems when handling your dried product because you will tend to pick up more than you intend due to its attraction properties.
The fluidized air system also allows for better heat transfer rates than other types of dryers because air gets so close to each piece of material as it passes through into the drum, which results in quicker drying times overall because there is less opportunity for water molecules being left behind on any surface they come in contact with during this process (including any type). There are also fewer chances for condensation inside between layers since there is no pressure difference between areas where moisture may be present (such as at the bottom) compared with those areas where little or no moisture could exist at all (like the top).
As a result, everything gets mixed up very nicely due to which better quality granules can be made.
As a result, everything gets mixed up very nicely due to which better quality granules can be made. The particles can collide with each other more effectively and they can grow rapidly.
This process is generally called “Granulation”.
Granulation is the process of mixing and forming granules. In this process, the wet powder is mixed with air at high velocity and at high temperature to form granules. This method of drying is generally called “Granulation”.
Therefore, for granulation, the wet powder that has been added to the pan of an fbd machine is mixed with air at high velocity to make all particles behave as an aerated liquid, which allows each particle to collide with other particles more effectively and rapidly resulting in the rapid growth of granules.
Fluid Bed Dryers are useful for pharmaceutical industries for mixing and drying purposes.
Fluid bed dryers are used in industries to mix and dry. The main purpose of using a fluid bed dryer is to ensure that the products are dried uniformly.
Fluid bed drying is done by heating the material inside a chamber that has a circulating fluidized bed of tiny particles and hot air. This helps in mixing, granulating, drying and so on. The heat transfer rate through convection is higher than conduction because fluidization increases the contact area with heated surfaces as well as increases particle velocity which results in faster heat transfer rates than other methods of drying like tray or belt type dryers.
