Rotary flash dryer The rotary flash dryer is ideal for processing filter cakes, paste-like materials, thixotropic materials, heat sensitive materials and granules, powder materials, in dyes, pharmaceuticals, pesticides, fine chemicals, chemical fiber, petroleum and Food and other industries have very broad application prospects.
Rotary flash dryer working principle
The flash dryer is a continuous drying equipment specially designed for filter cake, paste, and muddy materials . The cleaned heat medium enters the drying chamber from the tangential direction and forms a powerful swirling swirling airflow with the mechanical agitation mechanism. The wet material is metered into the drying chamber by a feeder and pulverized and dried by stirring and vortex flow. The top of the drying chamber is equipped with a particle size classifier. The fine powder is discharged from the top of the column, and is collected by the latter separator into a product. The larger particles are returned to the drying chamber and continue to be pulverized and dried.
Rotary flash dryer features
â—†Dry viscous materials: According to different materials, the feeder and the discharger take different forms, which can meet the requirements of automatic, continuous feeding and smooth discharge.
â—†zui good power matching: according to different material properties (density, bulk density, viscosity, fineness, initial moisture, final moisture, angle of repose, etc.), optional blower, induced draft fan, agitator, feeder, etc., to match power Zui good.
â—†Dry viscous material: The lower part of the dryer is in the shape of a cone with a crushing device and a flushing of the wall of the airflow, so that it can handle materials with certain viscosity.
â—† Dry heat sensitive material: Due to the short drying time, the relative speed of the material and hot air is large and the hot air is not in direct contact with the dry material, so it can be used to treat heat sensitive materials.
◆Drying strength: Due to the crushing, scouring, collision and surface area of ​​the material during the drying process, the hot air does not directly contact the dry material, so the inlet air temperature can be higher than the melting point of the material, so the drying strength of the equipment is large.
◆ Effective control of final moisture and fineness: The built-in material (swirl, ceramic ring or classifier) ​​is set through the drying tower and coordinated with the inlet air temperature to effectively control the final moisture and fineness of the finished product.
Food additives refer to chemical synthetic or natural substances added to food for the purpose of improving the quality, color, aroma and taste of food, as well as for the need of preservative and processing technology. Due to the rapid development of the food industry, food additives have become an important part of the modern food industry, and has become an important driving force of technological progress and technological innovation in the food industry. In the use of food additives, in addition to ensuring their due function and role, the most important thing is to ensure the safety and health of food.
