The chemicals, manufacturing, and refining industries use a variety of mechanical and thermal processes to attain a completed product. Flash drying process s a widely used process of drying particulate matter by exposing it very shortly to a high temperature gas stream, resulting in a rapid drying, without exposing the material to excessive heating. Flash drying has applications in several industries, including agriculture, food, chemicals, minerals, etc. This process can operate on a range of varied feed materials, including powders, cakes, granules, flakes, pastes, gels, and slurries. The feed for the flash drying process requires a relatively consistent particle size so that the material can flow smoothly through the flash drying equipment, without segregation and accumulation. This article gives a brief outline of the flash drying process.
Flash Drying Process
The process of flash drying begins with the wet feed being dispersed into a stream of heated air (or gas), which carries it through a drying duct. As the wet material is being conveyed through the flash dryer, the hot airstream evaporates all moisture from it. The dried material is segregated using cyclones, and/or bag filters. Most chemical industries need to adhere emission standards, and therefore the exhaust fumes from cyclone separators are passed through scrubbers or bag filters for final cleaning. Flash dryers are simple equipments that can be manufactured in various materials such carbon steel, stainless steel, and other alloys to meet your custom process and material handling requirements.
Benefits of Flash Drying
Flash drying is a simple process that enhances product quality and requires a simple equipment with very few moving parts. Flash drying equipment is cost-effective and can be easily integrated with other chemical, thermal, and mechanical process equipment. Flash dryers are low maintenance and can be cleaned easily, owing to their simple design features. Flash drying exposes materials to heat only for a very short duration, making it an ideal choice for materials that are sensitive to heat. Many flash dryers can be custom designed to recycle used air, which increases overall process efficiency and reduces energy costs. Flash dryers are used extensively in the food processing industries to remove moisture from granulated food products that can’t be dried used other processes like spray drying or rotary drying.
Flash drying process is simple yet effective , which is widely used in many industries to improve the quality of the final product. If you own a business that requires the use of flash drying process, get in touch of companies that design and manufacture specialty equipment such as a flash dryer.
