We have incorporated various automatic control systems that make the machine to adjust seamlessly to any change in operating conditions.

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.

In this capacity, Dr. Therefore, drying can be done within 10 to 40 minutes. The gas velocity is such that only the very fine material fraction is carried over to the dust collection equipment. For controlled removal of surface and bound moisture.

Ventilex Fluid Beds – the Shaking Transport

This is due to the many advantages that it offers over the conventional drying techniques. Bubbles form and collapse within the fluid bed of material promoting intense particle movement. Saintyco is a leading pharmaceutical machinery manufacturer ,We can provide you one stop solution for all your pharmaceutical equipment requirement. Design Hi-Temp Fluid Bed. This will delay the entire drying process rather than accelerate it. The drying process transits from the constant rate stage to the falling rate stage, and the bed temperature goes up.

Request A Quick Quote. We also classifi ed the DCPA materials into fi nes, medium, coarse, and examined the drying process for each size cut as well as mixtures. Plus, get special offers and more delivered to your inbox.

Fluidized bed drying – Glatt Integrated Process Solutions

The pressure drops across the distributor must be high enough to ensure good and uniform fluidization. Contact How can we help you? Fluidized Bed Drying of Pharmaceutical Materials: Remember, hiring untrained eryer will make your warranty invalid. In order to improve operation, efficiency, and reproducibility of a fluidized bed dryer, some parameters need to be controlled. Therefore, sticky or adhesive materials will not move hed, hence it will be nearly impossible to use this equipment.

Some powders and granules degrade or lose essential properties when subjected to extreme heat or temperatures. This surface evaporation also occurs at the constant rate stage. Processes Fluidized bed drying. Therefore the results for fine particles are not shown in this article.

Dryed, these are the main challenges you may face when intending to use this equipment. These high temperatures bef in more drying air volume, which means greener, more sustainable process characteristics and remarkable energy efficiency. The drying profiles shown in Figure 3 fluidixed that this fluidized bed drying process is a three stage process, including a short pre-heating stage, a constant rate stage and a falling rate stage.

It is for this reason that we may advise you to consider other alternatives. In many instances, several different types may provide similar performance at the same cost. This makes handling these machines easy and less labor intensive. Even with the high rate of mass and heat transfer, you can still control the basic parameters that affect quality of the final product. They include but not limited to.

Get a bdd Contact Us. The modern fluidized bed designs have sensitive and effective sensors that monitor all essential parameters during material drying process. This is quite clear from the modular and cGMP compliant designs of our fluid bed dryers for pharmaceutical machines. Once all the water in the bed voids is removed, convection drives the water inside the powder pores to flow towards the powder surface, and then water is evaporated at the surface.

This is the main reason why our modern fluid bed dryer for pharmaceutical industry come with electrical earthing. Various types of modified fluidized bed dryers have been developed and are applied fryer many industrial processes to overcome some of the problems encountered while using conventional fluidized bed dryer and for a drying process.

In addition, fluidized bed drying provides controlled and uniform drying conditions compared to the uneven sryer in trays. With further drying, the effect of convection reduces due to the loss of water and the drying front starts to penetrate inside the pores.

The inlet air temperature must be selected such that only so much moisture evaporates from the surface of the granulate as is transported through the capillaries from the interior of the granulate to the surface. Fluidieed any questions, freely to reach me,I will try my best to give you good advice drher solution.

Ventilex takes pride in matching our design to your fluid bed dryer fluudised, which results in cost savings for you. Our results indicate that if drying is carried out in a slow drying regime, where capillary flow is faster than evaporation, drying is dominated by the constant rate stage and the impact of particle size on drying is not signifi cant. In short, I highly recommend fluid bed dryer in pharmaceutical applications due to these numerous advantages and predictable performance.

However, it is important that you choose a suitable machine that matches the exact requirements of your applications. But before, I explore fluiised details about this; you need to know the working principle of fluid bed dryer.

Materials processed in a Fluidized Bed Dryer or Cooler float on a cushion of air or gas. By choosing the right combination of gas speed and mechanical movement, you can process granular products with a wide range of grain sizes successfully while minimizing dust drher fines, increasing yield. This is one of the main reasons why fluidization is common in most pharmaceutical industries.

A high turndown ratio of production capacity is possible and fluctuations of the feed rate are easily absorbed. Knowing that no rluidised applications are exactly alike, we take an engineered and systems approach for each installation. FDA and more than 40 global companies.
