High-voltage electric field film drying system

Abstract

The invention relates to the technical field of material drying, and discloses a high-voltage electric field film drying system. The high-voltage electric field film drying system comprises a film assembly, a dryer and a vacuum pump. The hot-side film surface of the film assembly is used for introducing hot water with a preset temperature, and the cold-side film surface of the film assembly sequentially communicates with the dryer and the vacuum pump through a first pipeline. A high-voltage electric field is arranged in the dryer. According to the high-voltage electric field film drying system, the high-voltage electric field drying technology and the film distillation technology are ingeniously coupled and are combined to dry the materials, so that the cost is low, the drying efficiency and the drying quality of the materials are greatly improved, and the high-voltage electric field film drying system is particularly suitable for drying high-added-value materials containing thermal instability active components.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a high-voltage electric field film drying system. Background technique [0002] Material drying involves drying fields such as agricultural production, food processing, pharmaceutical manufacturing, chemical production, paper making and wood processing. Through drying treatment, not only can obtain materials that meet the moisture content requirements, but also affect other properties of materials. [0003] High-voltage electric field drying technology is an electrohydrodynamic drying method. Under a high-voltage electric field, the electric field force has a traction effect on the polar water molecules in the material. The energy-carrying ions in the electric field are injected into the material, and the energy is transferred to the water molecules. The breakdown of molecular clusters accelerates the evaporation rate of water and improves the dehydration or thawing effi...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the above that although the high-voltage electric field drying technology realizes the drying of the material at a lower temperature and better ensures the biological activity of the material, there is a problem that the drying speed is relatively slow.

As far as membrane distillation technology is concerned, it is currently only used for the separation and purification of materials. In the process, the hydrophobic microporous membrane needs to be replaced frequently, which is not only cumbersome to operate, but also greatly increases the cost of the equipment

Based on this, there is currently no coupling of high-voltage electric field drying technology and membrane distillation technology to greatly improve the drying efficiency and drying quality of materials while reducing equipment costs
