How Does A Fluid Bed Dryer Work

Fluid bed technology is used for cooling heating and drying of bulk solids materials. How does a fluid bed dryer work.

Fluid Bed Equipment Process Diagram Fluidized Bed Fluid Granulation

Fluidized bed dryer also called fluid bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules.

How does a fluid bed dryer work. If air is allowed to flow through a bed of solid powdered material in the upward direction with the velocity greater than the settling rate of the particles the solid particles will be blown up and become suspended in the air stream. First the air flows through the bed of solids at a velocity sufficient to support the weight of the particles which creates a. This gas or air will move upwards through the spaces between the particles.

In continuous fluid bed dryer the material is dried in one section. A fluidized bed is typically constituted of a column which is containing the solid to fluidize mostly powders sometimes granules bed of particles. Fluid Bed Dryer has a rectangular or long trough structure.

When do the drying word the granular food raw material from the feeding device spread on the porous plate to form a layer of material thickness then. The high pressure hot air flow fluidizes the bed of material by contacting each particle. Fluid bed dryers work at an exceptional speed in getting rid of excess moisture from the granules and powders.

- Fluid Bed Dryers. The air velocity is adjusted to keep the moving layer of material fluidized. What does fluidised bed mean.

The wet particles are lifted from the bottom and cause the particles to behave as a fluid. In a couple of chapters I like to explain more about this technologyprocess and where the system can be used. The working area of the fluid bed is made of perforated plate thin steel plate punching fine wire braid or alumina sintered into porous ceramic plate.

Drying of the material occurs because of the direct contact between the sand and the hot drying air that is blown through a layer of the product. With the continuous fluid bed drying systems material flow over a perforated bed. Fluid bed dryers work on the principle of fluidization a process where a material is converted from a static solid-like state to a dynamic fluid-like state.

The Principle of Fluidized Bed Dryer. This hot gas pumps through the spaces between solid particles. Fluid bed heat exchange takes place by passing a gas most commonly air through a perforated distributor plate which then flows through a layer bed of solids.

You will save a lot of time hence boost the production process of different pharmaceutical products. Performs Multiple Functions You can use the fluid bed dryer to perform different functions in one particular standing. What is the purpose of fluidisation.

I often get the questions. The fluid bed dryer system blows hot drying air through the holes of a perforated plate. Moist material is fed onto a shaking perforated steel bed through which the drying air flows.

It has such functions as mixing. Then cooling takes place in the second section. The air performs two functions.

How does a fluidisation work. Application The machine is a process machine widely applied for solid preparation production in the pharmaceutical industry. In this process hot gas or air is introduced through a perforated distribution plate into the area holding the material.

First the material is fed on the shaking steel bed through which hot air flows. On top of the column a gas exhaust is installed. Fluid bed dryer works on a principle of fluidization of the materials.

The airflow is controlled throughout the length of the dryer to maximize fluidization to handle wet and sticky materials. A Ventilex Fluid Bed DryerCooler is a machine in which a continuous flow of wet granular material is dried and subsequently cooled. Through this bed machine blows air to achieve the fluidization process.

The equipment works on a principle of fluidization of the feed materials. How does a Fluid Bed Dryer work. How Does Fluid Bed Dryer Work.

In fluidization process hot air or gas flow is introduced through the bed of solid particulates. The air is of sufficient volume that it lifts or fluidises the bed of material allowing intimate contact with each particle.
