| In order to meet the higher technical requirements of rapid thawing for frozen food in hotel catering industry, a microwave thawing preservation device was designed. Taking the STM32F103 as the control processor, the software was used to control the microwave thawing device by collecting the temperature, humidity, weight and equipment status of the defrosting chamber by software filtering algorithm, incremental PID temperature control algorithm and Newton iteration algorithm. Fresh storage device, humidification atomization device, sterilization device, etc. were controlled to complete the rapid freezing of frozen food preservation. Experiments show that the thawing time and the quality of the sample have a certain linear relationship, the sample thaw quality can be guaranteed. The device can meet the design technical requirements, which has broad market prospects. |
