In physics and chemistry, flash freezing is a naturally occurring phenomenon used commonly in the food industry and by meteorologists for the purpose of forecasting. The process is also of great importance in atmospheric science, as its study is necessary for a proper climate model for the formation of ice clouds in the upper troposphere, which effectively scatter incoming solar radiation and prevent Earth from becoming overheated by the sun.
Adaptive temperature zoning control system and method for flash freezing equipment
The application discloses a self-adaptive temperature zoning control system and method for a flash freezing device, relates to the technical field of intelligent temperature control of the flash freezing device, and is used for solving the problems of uneven temperature control, abrupt adjustment of adjacent zones and insufficient adaptability in the freezing process. The freezing treatment area is divided into multiple temperature zones along the conveying direction of the object to be frozen. The air temperature, supply air temperature, return air temperature, surface temperature of the object to be frozen, conveying speed and zone coverage rate are collected. The temperature demand value, heat load characteristic value and temperature trend determination value are calculated. The target adjustment temperature and self-adaptive adjustment amount are generated. The adjacent zone boundary state is coordinately controlled. According to the adjustment result, the correlation coefficient is feedback corrected. The self-adaptive, continuous and refined control of the flash freezing process is realized.
