Kin of humic acid salt dry using a large-scale spray drying equipment to ensure that the annual output of 20,000 tons of finished product; this device is 8.5 meters in diameter spray dryer tower plants with a total tower height of 18 meters; use of materials on the inner wall of the tower of stainless steel, with a color plate outsourcing spray dryer, use a steel skeleton, making the device in the economic and practical circumstances to take into account the material properties. The device production process is simplified, suitable for continuous control of production, moisture content of 40-90% of the liquid, once dried into a powder, to reduce the crushing, screening and other processes to improve product purity. Kin of rare dryer make 50% of the original moisture content of the material is dried to 5% or less, the amount of water evaporated per hour 150Kg centrifugal spray dryer, equipment inlet air temperature and the air temperature was 350 ℃ and 130 ℃, making the device dry finished more accurate. The product was collected on the use of a cyclone, to ensure complete recovery of the material. On the device material, and material contact parts made of stainless steel, more economical and practical. In addition, in order to prevent the material in the tower under dry cone piled high temperature zone, designed with a smaller lower cone angle so that the powder from the discharge port in a timely manner, to ensure product content. For the guide vane angle hot air distributor is set to be adjusted, it is possible to get the best distribution of hot air in the drying tower, you can reduce the phenomenon and strengthen dry sticky wall. After air drying medium heated by the heater filtered with a filter medium spray dryer, and then flows into the drying tower by hot air distributor top of the column; the material to be dried is fed by the screw pump nebulizer, under the action of centrifugal force to form fine droplet. In hot and dry indoor water evaporation and drying droplet contact group into powder, powder recovered by cyclones become qualified products. Exhaust contains moisture into the atmosphere by the induced draft fan. Spray Dryer management, Kinder dry (certified), spray dryer is provided by Changzhou Drying Equipment Co., Kinder.
