You will find two most significant dryers used by pharmaceutical and chemical machinery. Usually the one is really a fluid bed dryer used for drying granular, crystalline materials and second is really a tray dryer used for drying chemical powders.
The industrial dryer has become a versatile tool in the workshop. Each kind of dryer features a specific design for the intended purpose. These machines are applied in many different industries, including pharmaceuticals, chemical manufacturing and food processing. Large and high capacity dryers are also manufactured for large businesses. Here, we are likely to discuss about two types of dryer machines, which are playing very versatile role in today's industry. Essicatori Professionali The first is fluid bed dryer and another is tray dryer. Fluid bed dryer involves drying, cooling, agglomeration, granulation and coating of particular materials. It is great for wide selection both heat sensitive and non-heat sensitive products. Uniform processing conditions are achieved by passing a fuel via a product layer under a controlled velocity to create a fluidized state for drying. In fluid bed drying, heat is supplied by the fluidization gas, however the gas flow do not need to be the only real source. Heat may be effectively introduced by heating surfaces by immersing panels or tubes in the fluidized layer https://maximind.ca/.
Fluid bed drying is suited for powders, granules, agglomerates and pellets having an average particle size normally between 50 to 5000 microns. Very fine, light powders or highly elongated particles may require vibration for successful fluid bed drying.
In fluid bed dryer, conditioning of the gas may be required to achieve sufficient product cooling in a economy sized plant and to get of volatiles. Heat are often removed by cooling surfaces immersed in the fluidized layer. Fluid bed dryer offers important advantages over other methods of drying particulate materials. Particle fluidization by fluid bed dryer gives easy material transport, high rates of heat exchange and high thermal efficiency while preventing overheating of individual particles. Other important properties of fluid bed dryer are fluidization gas velocity, fluidization point, equilibrium volatile content and heat transfer coefficient for immersing heating surfaces https://peacefullendings.com/.
Another important dryer on the market is tray dryer. Tray dryer is a commercial device using heat to dry a wide range of flat trays at one time. The processed trays can contain many different materials, which range from food products to chemical experiments. It is mainly utilized in the pharmaceutical industry, in dies for chemical industry, food industries and dairies, polymer and biochemical industry. Regardless of products drying on the tray, each dryer uses warm, dry air forced through blowers in a sealed area. The three types of tray dryers are batch, semi-continuous, and cross flow models. Tray dryer can be used to discover the best drying reserves in conventional processes. It's double walled cabinet with one or two doors. The gap between the two walls is filled with light resin bounded by fiber glass, wool insulation material to prevent heat transfer. Doors are given gaskets to prevent air leakages from the front side of the door. Stainless trays are placed inside the chamber. Efficient air re-circular system is usually to be used by tray dryer. Fresh air along with heated air in proper proportion is usually to be inserted in to the dryer for optimum drying. The tray dryer is designed in this way that the most effective and bottom materials dry simultaneously. This blend of air is circulated in the tray dryer even once the dryer's temperature is under controlled.
