[0002] As we all know, in order to extend the shelf life of fruits and vegetables, a freezing and fresh-keeping device is needed to store them. The cold storage can slow down the metabolism of fruits and vegetables and put them in a near-dormant state, so that the texture, color, taste, nutrition, etc. of fruits and vegetables can be maintained for a long time, thereby achieving a long-term preservation effect; the existing agricultural fruit and vegetable freezing and fresh-keeping storage device cannot be placed in layers according to different types of fruits and vegetables. When there are many fruits, they will be piled up, which will cause the bottom fruits to be squeezed and damaged, reducing the preservation time of fruits and vegetables, and the storage space cannot be adjusted according to the volume of fruits and vegetables, making it difficult to make full use of the space. When the existing fresh-keeping storage device stores fruits and vegetables, water droplets on the surface of fruits and vegetables are very likely to accumulate at the bottom of fruits and vegetables, accelerating the corruption of fruits and vegetables.
