2 Essential Devices : Liquid Mattress Dryer and Tray Dryer.

You can find two most significant dryers used 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 become a versatile tool in the workshop. Each kind of dryer has a specific design for the intended purpose. These machines are applied in a variety of industries, including pharmaceuticals, chemical manufacturing and food processing. Large and high capacity dryers are also manufactured for big businesses. Here, we are going to discuss about two types 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 range both heat sensitive and non-heat sensitive products. Uniform processing conditions are attained by passing a gas via a product layer under a controlled velocity to produce a fluidized state for drying. In fluid bed drying, heat is supplied 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 suited to powders, granules, agglomerates and pellets with 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 pick up of volatiles. Heat may also be removed by cooling surfaces immersed in the fluidized layer. Fluid bed dryer offers important advantages over other ways 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 a commercial device using heat to dry a large amount of flat trays at one time. The processed trays can contain a variety of materials, ranging from food products to chemical experiments. It is mainly found in the pharmaceutical industry, in dies for chemical industry, food industries and dairies, polymer and biochemical industry. Regardless of the products drying on the tray, each dryer uses warm, dry air forced through blowers in a closed area. The three types of tray dryers are batch, semi-continuous, and cross flow models. Tray dryer is employed to find the best drying reserves in conventional processes. It's double walled cabinet with one or two doors. Disidratatore Professionale The gap between the two walls is filled up with light resin bounded by fiber glass, wool insulation material to prevent heat transfer. Doors are given gaskets to prevent air leakages from the leading side of the door. Stainless trays are placed in the chamber. Efficient air re-circular system is usually to be used by tray dryer. Fresh air along side heated air in proper proportion is usually to be inserted into the dryer for optimum drying. The tray dryer was created in this way that the most effective and bottom materials dry simultaneously. This mixture of air is circulated in the tray dryer even when the dryer's temperature is under controlled.
