It cools fruits and vegetables so that they can be kept cool for a long time in the distribution process by stopping the growth of their own cells, preventing the consumption of nutrients and suppressing the propagation of various bacteria by quenching them in the cooling water.

In a typical configuration of the conventional fruit and vegetable cooling device, a conveyor is installed on the bottom of the cooling water tank containing the cooling water, and the vegetables or fruits to be cooled are put into the cooling water tank to be cooled, and the cooled fruits and vegetables are transported out of the cooling water tank by the operation of the conveyor. There is something that can be done. The prior art fruit and vegetable cooling device is a type of cooling the fruits and vegetables to the cooling water of the cooling water tank and transfers the cooled fruits and vegetables to the outside of the cooling water tank. In addition, the fruit and vegetable cooling device of the prior art is not deeply immersed in the cooling water of the cold water tank when the fruit and vegetable to be treated is light vegetables, so that the cooling treatment efficiency is inevitably lowered to solve the problem. In order to do this, the cooling treatment time must be long. In addition, when the fruits and vegetables cooled by the conveyor are transferred out of the cooling water tank after the cooling treatment, a large amount of cooling water remains on the surface of the fruits and vegetables, and the fruits and vegetables must be left for a relatively long time until such cooling water is naturally dehydrated. There is a flaw.
