Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a microwave drying equipment with a multi-layer conveying device, which is used for conveying industrial production such as microwave low-temperature drying agricultural products. Background technique [0002] Microwave heating uses the principle of dielectric loss, and the dielectric loss of water is much larger than that of dry matter, and most of the electromagnetic energy is absorbed by the water in the material. Microwave heating can form an internal heat source in the material, which can change the direction of steam migration and mass migration in the conventional heating and drying process, forming a unique mechanism of microwave drying. In the microwave drying process, the temperature gradient, heat transfer and vapor pressure migration direction are all from the inside to the outside at the same time, so that the moisture migration conditions during the d...
