A microwave vacuum dehydrator is a device that combines microwave heating and vacuum technology to dehydrate materials. The microwave generator in the device produces high-frequency electromagnetic fields. Water molecules in the material are polarized under the action of the alternating electromagnetic field and move at high speed, generating frictional heat to achieve uniform heating from the inside out. At the same time, the vacuum system in the equipment can promptly discharge the evaporated water vapor, creating a vacuum environment that further lowers the boiling point of water and accelerates water evaporation, thus realizing low-temperature drying.
Low-temperature and High-efficiency Drying: It can efficiently dry at relatively low temperatures, usually between 10°C and 30°C. The vacuum environment lowers the boiling point of water, and the instantaneity and penetrability of microwave heating can directly act on the water molecules inside the material, enabling rapid vibration and heat generation for uniform heating and quick drying.
Protection of Heat-sensitive Components: The low-temperature drying method helps protect heat-sensitive components in the material, such as vitamins, enzymes, and pigments, preventing them from being destroyed or losing activity at high temperatures, which is of great significance for maintaining the quality and nutritional value of the material.
Reduction of Oxidation Reaction: The vacuum environment reduces the contact between the material and oxygen, lowering the occurrence of oxidation reactions, which is helpful for maintaining the original flavor and color of the material.
High Production Efficiency: The fast drying speed greatly shortens the production cycle. For example, it can complete a task that requires 24 hours in other low-temperature drying processes in 40 minutes.
Energy Conservation and Environmental Protection: The microwave heating process does not produce harmful substances and waste, meeting environmental requirements. At the same time, the vacuum environment also reduces the emission of dust and harmful gases, further enhancing its environmental performance.
Easy Operation and Control: Modern microwave vacuum dehydrators are usually equipped with intelligent control systems that can achieve automatic control and precise adjustment of the drying process. Users can set and adjust drying parameters through the control panel or remote control system for real-time monitoring and remote management.
