Abstract: 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° C.-−3° 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.
