Description

Vacuum bipyramid desiccator

Technical Field

Background

As special drying equipment for reducing moisture by using heat energy, dryers are classified into two main types, i.e., a normal pressure dryer and a vacuum dryer. Vacuum drying has been widely used in the processes of concentrating, drying and mixing materials in chemical, pharmaceutical and food industries due to its advantages of high drying speed, less residual materials, low boiling point, high safety, etc. The vacuum double-cone dryer adopts a mode that a heat-conducting medium is added into a jacket under a vacuum state, and the medium is heated and then is transferred to the inner wall of the cone to dry wet materials in the cone, so that the drying of the materials is realized. In the drying process, the water vapor is continuously pumped away by the vacuum equipment after the wet materials are heated, and the tank body is continuously turned up and down, so that the vacuum double-cone dryer has high drying speed and high efficiency. Most of the existing double-cone dryers adopt a stirrer-free double-cone rotary drying mode, and hardening and fusion cakes are easy to generate due to the high rotary speed; because the distance between the supporting shafts on two sides of the cone is far or the single-side cantilever beam is adopted for supporting, the cone has poor structural stability and is not suitable for high-density materials, and the drying efficiency is far too high to meet the requirement of rapid use.
