Description

Technical fields:

[0001] This utility model relates to the field of dehydration and drying technology, specifically to a microwave rapid dehydrator with multi-band dynamic power control. Background technology:

[0002] Existing microwave dehydration equipment mostly employs a single fixed frequency band and power output mode, making it difficult to adapt to the dynamic needs of different materials during the dehydration process. While some equipment has power adjustment capabilities, it lacks a real-time monitoring and feedback mechanism, often resulting in localized overheating or incomplete dehydration. Furthermore, the material trays in traditional equipment are mostly stationary, leading to uneven microwave energy distribution and low dehydration efficiency. Inadequate moisture exhaust path design further affects the dehydration rate. Simultaneously, most equipment lacks integrated control of temperature, humidity, and microwave parameters, requiring frequent manual intervention and failing to meet the demands of automated continuous production. Therefore, a new type of equipment integrating dynamic control and high-efficiency dehydration functions is urgently needed to solve these problems. To this end, this invention proposes a microwave rapid dehydrator with multi-band dynamic power control to address the shortcomings and deficiencies of existing technologies. Utility model content:

The multi-band microwave generator 003 integrates three independent microwave generators, which respectively output high-frequency band 2450MHz±50MHz, mid-frequency band 915MHz±30MHz, and low-frequency band 433MHz. MHz±10MHz, frequency band switching and continuous power adjustment are achieved through the touch screen of control panel 002; a storage tray 004 is installed at the bottom of the dehydration chamber 001, and the bottom of the storage tray 004 is installed in the dehydration chamber 001 through a rotating shaft seat 005.
