An intelligent identification cooking system of an oven including an image acquisition system, an image analysis and processing system, and a temperature measurement and monitoring system. The image acquisition system is connected to the image analysis and processing system and an intelligent menu control system is connected to the image analysis and processing system and the temperature measurement and monitoring system respectively. Through computer vision and identification technology and temperature sensing technology, parameters such as the type, thickness, size, fattiness and temperature are identified and automatically matched and calibrated to a cooking menu. A control program is output to a control terminal and executed.

The invention discloses a method for rapidly predicting freezer storage time of frozen pork based on reflectance ratio of two near-infrared bands. Firstly, the near-infrared spectra information of the frozen pork is obtained by a near-infrared spectrometer, and the near-infrared spectra are analyzed to obtain center values of bands centered on 1500 nm, 1350 nm and 1890 nm characteristic peaks. The ratio thereof is treated as a eigenvector, which is substituted into the characteristic exponential function based on the eigenvector and freezer storage time to calculate the freezer storage time of frozen pork. By near-infrared spectroscopy technology, the invention directly detects the freezer storage time of pork in a frozen state, significantly reduces the time required by the conventional method, and has the advantages of being fast and non-destructive.

Disclosed herein is a multi-temperature-region ice-temperature fresh keeping storehouse and a fresh keeping method for bergamot pears that includes a precooling region, a feeding and discharging channel, a cooling region, an ice temperature detection device, a grading device, a conveyer belt control device, an automatic storage device, and a temperature rise and fall buffering channel. The cooling region includes four freezers, with temperatures ranging from 0&#xb0; C.-&#x2212;3&#xb0; C. The four freezers are connected level by level according to a temperature reduction rule. The present disclosure implements multi-temperature-region graded storage of bergamot pears according to the value of an ice point temperature of the bergamot pears, so that they are always stored close to the ice point temperature without freezing, thereby preventing freeze injury, and prolonging shelf life.
