Features dryer drum scraper ◎ operating flexibility, wide applicability. Adjustable many factors drum dryer drying. As concentration of the feed, the film thickness of the coating material, the temperature of the heating medium, the speed of rotation of the drum dryer starch residue, can change the drying efficiency of the dryer drum, and no interaction of many factors implicated. This brings great convenience to the drum drying operation, so that it can adapt to a variety of dry materials and different production requirements. ◎ short drying time. Drying cycle of materials generally only 10-300 seconds, suitable for heat-sensitive materials. If provided in a vacuum tumble dryer vessel can be run under reduced pressure. ◎ drying rate. Due to the cylinder wall coating put on very thin film material, generally 0.3-1.5mm, and heat and mass transfer in the same direction, the film surface can be expected to maintain strong evaporation 20-70kg.H2O / m2.h of. Vacuum drum dryer drum is sealed in a vacuum chamber organic fertilizer dryer, a material way in the form of material sealed storage hopper discharge gap. Drum dryer in a vacuum dryer kaolin, can greatly improve the heat transfer coefficient, for example in the roll temperature 121 ℃ (i.e. 0.2MPa vapor pressure), operating under vacuum conditions 870kPa, the heat transfer coefficient is operating at atmospheric pressure 2 to 2.5 times. However, due to the structure of the vacuum drum dryer is more complex, high drying costs, it is generally only used for juice, yeast, baby food is very heat-sensitive materials like dried mud ore dryer, dryer, rich manufacturing experience by households Changzhou Lake dry Engineering Limited. Changzhou Lake Drying Engineering Co. (www.longhudry.com) strong, credible, in Changzhou, Jiangsu drying equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Lake dry and you hand into the brilliant, for a better future!
