What is the working principle of the vacuum rake dryer?
Date: 2024-04-16Read: 7
The vacuum rake dryer is particularly suitable for drying heat sensitive materials, materials that are prone to oxidation at high temperatures, materials that are prone to hardening during drying, and materials that require the recovery of steam emitted during drying. After drying, the material is in powder form, so it is more suitable for finished products in powder form. After drying, it can be directly packaged without crushing. Drying of materials in industries such as medicine, food, and chemical: suitable for pulp, paste, and powder materials. Thermally sensitive materials that require low-temperature drying. Easily oxidizable, explosive, strongly irritating, and highly toxic materials. Require the recycling of materials containing organic solvents. The dried material can be in the form of slurry, paste, granular, powdery or fibrous, and has been widely used in the production process of solid sodium (potassium) alcoholate.
What is the working principle of the vacuum rake dryer?
The dried object is added from the middle of the shell, and under the continuous rotation of the rake teeth, the material moves back and forth in the axial direction. The surface in contact with the inner wall of the shell is constantly updated, and is indirectly heated by steam. The uniform stirring of the rake teeth and the crushing of the crushing rod make it easier to discharge the surface moisture of the material. The vaporized moisture is discharged from the vacuum pump outlet through the dry dust collector, wet dust collector, and condenser.
