[0002] During the cultivation process of kelp seedlings, in order to maintain their freshness and extend their shelf life, the kelp seedlings need to be air-dried.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed "a kelp air-drying device capable of recycling heat energy", and its application number is "201820427852.2". The above patent mainly includes a drying chamber, a blasting device, a controllable heating device, a temperature detection device, a conveying device, an exhaust pipe, a condensate collection device and a heat exchanger; the blasting device includes a support, an air filter, an air inlet, a circulating fan, and an air outlet; the exhaust pipe is arranged at the lower right side of the drying chamber, and the exhaust pipe includes an exhaust port and a hot air collector, and the hot air collector is connected to the condensate collection device through a heat exchanger. Although the above utility model solves the shortcomings of general air-drying devices that do not fully utilize the heat energy generated after air-drying, resulting in waste of resources. However, when the kelp seedlings are placed on the conveyor belt for transportation, when the hot air passes through the kelp seedlings on the conveyor belt, the heat is transferred to the kelp seedlings. Since one side of the kelp seedlings is directly exposed to the air, it is greatly affected by the hot air, while the other side is less affected by the hot air in contact with the conveyor belt, which easily leads to uneven heating on both sides of the kelp seedlings; and the drying chamber is difficult to ensure the closedness of the drying chamber due to the setting of the conveyor device, which not only easily leads to heat loss from the installation place of the conveyor device, but also affects the drying quality of the kelp seedlings. Therefore, the utility model provides a kelp seedling cultivation air-drying device that can recycle heat energy to solve the problems raised in the above background technology.
