Vacuum Spiral Continuous Drying System

The vacuum spiral continuous drying system is a new - type drying system. Its main machine is mainly composed of a power part, a transmission hollow shaft, screw blades, and an outer cylinder jacket. During the drying process, both the screw blades and the outer cylinder jacket are filled with hot media, and the continuous drying of materials is achieved through the full contact and heat transfer between their surfaces and the materials under vacuum conditions.

The hot media can be steam, hot water, or heat - conducting oil. The heating temperature can be controlled in sections according to the moisture content changes of the materials during the drying process to avoid over - baking of the materials. The drying time, heating temperature, and working vacuum degree of the materials can all be automatically adjusted. The drying system has low energy consumption, a high degree of automation, and is easy to operate. At the same time, it realizes the full - closure of the evaporation - related medium, the organized recovery and utilization, saves production costs, and is safe and environmentally friendly.
