The pore volume and the surface area of the DCPA material are 0. This indicates that if drying is dominated by the constant rate stage, the impact of powder size on drying is not fluidiseed.

Ventilex Fluid Beds — the Shaking Transport Ventilex Fluidized Beds are known worldwide for their high quality and operational efficiency.

Additionally, you can choose the right capacity of the fluid dryer where there is fluiddised excellent mixing of both the particles and air. The constant rate stage corresponds to a constant bed temperature.

Ventilex Fluid Beds – the Shaking Transport

The moisture content in the product during drying was measured using two approaches: For controlled removal of surface and bound moisture.

In many instances, several different types may provide similar performance at the same cost. Sometimes to save energy, the exit gas is partially recycled.

It should be noted also that not all modified fluidized bed dryers are necessarily better than the conventional dryers in terms of product quality, or energy efficiency, or drug performance.

Hot air or gas reaches every surface of the particles. Muzzio directs research involving the U. If any questions, freely to reach me,I will try my best to give you good advice and solution.

In the pharmaceutical industry, the drying step in many pharmaceutical production lines is often a bottleneck because this process is affected by many parameters and it is difficult to determine the time required to dry the materials as well as analytically verify that a predetermined end point has been reached. Get a quote Contact Us. The drying process for fine particles was also examined in this work. With further drying, the effect of convection reduces due to the loss of water and the drying front starts to penetrate inside the pores.

Therefore, sticky or adhesive materials will not move freely, hence it will be nearly impossible to use this equipment.

Fluidized bed drying

Remember, the hot air or gas surrounds all particles and this ensures efficiency in the material drying process. Furthermore, with the modular design, you can easily replace fluidized modify this machine to suit your unique applications.

By choosing the right combination fluidisd gas speed and mechanical movement, you can process granular products with a wide range of grain sizes successfully while minimizing dust and fines, increasing yield. Ventilex systems energy efficiency results in l bdd operating costs for your process, while our simple drive, high quality materials, and minimal dust or fines formation l ower maintenance costs and increase yieldsas well. This is due to good mixing of solids and intensive heat and mass transfer between the solid and hot gas phases in the system.

Contact How can we help you? SaintyCo HeyI am TonyGeneral manager of Saintyco and expert in pharmaceutical equipment industry for over 20 years, I would like to share my experience in the field. In this article, I am going to explore all the advantages and disadvantages of fluid bed dryer. Ideal for removal of surface and bound moisture in powder, crystalline or granular materials Good thermal efficiency Can handle a wide range of materials, particle size distributions and material cohesiveness Enables quick replacements, minimizing shutdown times and maintenance requirements, especially useful for hygienic applications Enables energy savings and system integration Plug flow is especially suited to products that require longer residence time and a relatively tight moisture specification For use as an elutriator or avoid excessive carry-over Good when turndown is required Enables high inlet temperatures for non-heat sensitive products which reduces the capital and running costs Reduces airflow and plant size and improves cost, emissions and power consumption.


It is important to note that the profiles of the moisture content and the bed temperature were quite similar for large particles, tluidised particles and mixtures. Once all the water is removed from the materials, a plateau can be observed for the bed temperature indicating that the system reaches an equilibrium state. Clearly, you can choose a machine that meets your material drying needs.

Very high heat and mass transfer rates are obtained as a result of the intimate contact between individual particles and the fluidizing gas. Processes Fluidized bed drying. Contents 1 Parameters to be controlled in fluidized bed dryers system 1.

Properly used, fluidized bed drying provides an efficient solution for the gentle and even drying of your product. Sample moisture content vs. The gas velocity is such that only the very fine material fraction is carried over to the dust collection equipment. This makes handling these machines easy and less labor intensive.
