A Composite Intelligent Vacuum Drying Dynamics Experiment Platform

Abstract

The invention discloses a complex intelligent vacuum drying dynamics experiment platform which comprises a vacuum system module, a temperature control module, a data acquisition module, and a control system module. The vacuum system module includes a vacuum drying chamber. The temperature control module is used for controlling the temperature of the vacuum drying chamber. The data acquisition module consists of a material group data acquisition module and a reference group data acquisition module. Compared with the prior art, the complex intelligent vacuum drying dynamics experiment platform can intelligently keep the experiment temperature stable, can be directly used in research of experiments like vacuum pulse drying and infrared vacuum drying, and can adapt to the requirements of different drying experiments. The amount of heat absorbed or discharged in real time by materials in the drying process can be obtained by recording the change relation of the power difference between compensation heating wires of a material plate and a reference plate with time. The reference plate can directly replace blank test in experiment. The influence of the surrounding environment is avoided, and the result is more accurate.

Description

technical field [0001] The invention relates to the technical field of vacuum drying equipment, in particular to a composite intelligent vacuum drying dynamics experiment platform. Background technique [0002] Vacuum drying, also known as analytic drying, is a drying method that puts materials under negative pressure conditions, and appropriately heats them to reach the boiling point under negative pressure, or cools down to make the materials solidify and then dry the materials through the melting point. Vacuum drying technology uses the principle that the melting point and boiling point of water will decrease with the increase of temperature. At the same time, it is supplemented by vacuum pump to dehumidify and reduce the water vapor content, so that the water and other solutions in the material can obtain enough kinetic energy to separate from the surface of the material. Due to the isolation of air under negative pressure, vacuum drying can better maintain the original ...
