You will find two most significant dryers utilized by pharmaceutical and chemical machinery. The main one is a fluid bed dryer used for drying granular, crystalline materials and second is a tray dryer used for drying chemical powders.
The industrial dryer has changed into a versatile tool in the workshop. Each kind of dryer has a specific design because of its intended purpose. These machines are applied in a number of industries, including pharmaceuticals, chemical manufacturing and food processing. Large and high capacity dryers may also be manufactured for large businesses. Here, we are going to discuss about two kinds of dryer machines, which are playing very versatile role in today's industry. The foremost is fluid bed dryer and another is tray dryer. Fluid bed dryer involves drying, cooling, agglomeration, granulation and coating of particular materials. It is ideal for wide variety both heat sensitive and non-heat sensitive products. Uniform processing conditions are attained by passing a fuel through a product layer under a controlled velocity to make a fluidized state for drying. In fluid bed drying, heat is furnished by the fluidization gas, but the gas flow will 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 fitted to powders, granules, agglomerates and pellets by 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 accomplish sufficient product cooling in a economy sized plant and to get of volatiles. Heat may also be removed by cooling surfaces immersed in the fluidized layer. Fluid bed dryer offers important advantages over other types 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 in the industry is tray dryer. Tray dryer is an industrial device using heat to dry a large amount of flat trays at one time. The processed trays can contain a number of materials, ranging from food products to chemical experiments. It is mainly used in the pharmaceutical industry, in dies for chemical industry, food industries and dairies, polymer and biochemical industry. Whatever the products drying on the tray, each dryer uses warm, dry air forced through blowers in a closed area. The three kinds of tray dryers are batch, semi-continuous, and cross flow models. Tray dryer is employed to find the best drying reserves in conventional processes. Disidratatore Professionale It is double walled cabinet with 1 or 2 doors. The gap between the 2 walls is full of light resin bounded by fiber glass, wool insulation material to avoid heat transfer. Doors are provided with gaskets to avoid air leakages from the leading side of the door. Metal trays are positioned within the chamber. Efficient air re-circular system is to be utilized by tray dryer. Outdoors along with heated air in proper proportion is to be inserted in to the dryer for optimum drying. The tray dryer is designed in such a way that the most truly effective and bottom materials dry simultaneously. This combination of air is circulated in the tray dryer even when the dryer's temperature is under controlled.
