Wirbelschicht-Trocknungsanlage, Wirbelschichttrockner

Working principle: When air is purified and heated, it is introduced from the bottom of induced-draft fan and passed through the screen plate of raw material. In working chamber, the state of fluidization is formed through stirring and negative effect. The moisture is evaporated and removed rapidly, and the raw material is dried quickly. Features: 1) The structure of fluidization bed is round, so as to avoid dead corner 2) Inside the hopper there is a stirrer in order to avoid agglomeration of raw material and forming canal of flow 3) The granule is discharged in the method of turning over. In this way it is very convenient and full. The discharging system can be designed as per requests as well 4) It is operated at the conditions of negative pressure and seal. The air is filtered. Therefore, it is simple in operation and convenient in cleaning. It is an ideal equipment in conformity with the requirements of GMP 5) The drying speed is fast and temperature is uniform. In general, the drying time is 15 - 45 minutes each batchScope of applications: 1) Use screw to extrude and vibrate granule, and granulate granule with the method of humidity, high speed and mixing 2) Suitable for drying humidity block or powder raw material in the fields, such as pharmaceutical, foodstuff, feed stuff, chemical industries 3) The raw material is large in granule and small in block, and has adhesive property 4) Suitable for raw materials, its volume will be changed when dry, such as giantarum, polyacrylamide Main technical specifications Item Type Raw material Kg 60 100 120 150 200 300 500 Fan Air volume m3/h 2361 3488 4000 4901 6032 7800 10800 Air pressure mmH2O 594 533 533 679 787 950 950 Power kw 7.5 11 15 18.5 22 30 45 Stirring power kw 0.55 0.55 0.55 0.55 0.55 0.75 0.75 Stirring speed rpm 11 Consume of steam kg/h 141 170 170 240 282 366 451 Time of operation min 15-30 Height of main machine Square mm 2750 2850 2850 2900 3100 3300 3650 Round mm 2700 2900 2900 2900 3100 3600 3850
