Nauta conical dryer is an efficient, fully sealed, multifunctional vertical vacuum drying equipment integrating drying and mixing, using the spiral belt to rotate and lift materials, meanwhile, simultaneously filling the conical jacket and the hollow spiral belt with the heat transfer medium (such as hot water, heat transfer oil, steam, etc.), so that the heated materials can be lifted from all around, and fall in the middle, then quickly and continuously turn over. The water vapor is taken away in time through vacuum pumping in the cylinder, so that materials can be dried and mixed in a short time. Structural Features and Functions 1. Heated internally by the jacket and spiral belt, the heating surface of the equipment has been enlarged by 40%. 2. The single spiral belt agitator used in the equipment is a patented product of our company, which can achieve cycle-mixture from bottom to up with good performance of efficient forced heat transfer. When the material loading rate is 40% ~ *, the heating utilization of * can be realized. It is applicable for mixing and drying fine materials. 3. Completely sealed system, without pollution of foreign matter, high purity, especially applicable for mixing and drying of pharmaceutical intermediates, APIs and sterile APIs. 4. The gap between the single spiral belt agitator and the container wall is so small that can effectively prevent materials from adhering to the surface of the container wall. 5. The conical cylinder structure with small angle is adopted to make discharge fast and clean, without accumulation.
