The present invention relates to a circulating mushroom cultivation apparatus, and it is characterized in that a plurality of feed trays 11 are vertically spaced to form a multi-layer cultivation space, A support guide 10 provided with guides 13 and capable of adjusting the length according to the quantity and size of the conveyance tray 11, a conveyance tray 11 disposed at both longitudinal ends of the support guide 10, A first lift 20 which is lifted and lowered in a state in which the feed tray 11 is discharged and a lowering operation is performed in a state in which the feed tray 11 is discharged, a first lift 20 disposed at an outer side of the first lift 20, A second lift 30 which is operated to descend in a state in which the conveyance tray 11 is inserted and the elevation operation is performed in a state in which the conveyance tray 11 is discharged, And is movable up and down, And a traction device (40) for traversing the lowered transfer tray (11) and transferring it to the support guide (10) side.Accordingly, the present invention provides a uniform growth environment as the mushroom is cultivated in a state where the temperature and the humidity are kept constant on the conveyance tray which is circulated and transported, and the growth of the mushroom is uniform without any variation, It is possible to cultivate mushroom easily and it is possible to efficiently manage mushroom by supplying mushroom culture medium at a fixed position and harvesting the grown mushroom. Since the internal air is circulated naturally during the circulation process of the transfer tray, Since contamination of mushrooms is prevented, the quality of cultivated mushrooms is improved and the commerciality is improved.본 발명은 순환식 버섯재배장치에 관련되며, 구성에 특징을 살펴보면, 복수개가 상하로 이격배치되어 다층의 재배공간을 이루고, 상측 길이방향을 따라 다수개의 이송트레이(11)가 직렬 거치되며, 확장가이드(13)가 구비되어 이송트레이(11)의 수량과 크기에 따른 길이조절이 가능한 지지가이드(10), 상기 지지가이드(10)의 길이방향 양측 단부에 배치되며, 상측에 이송트레이(11)가 투입된 상태에서 승강작동되고, 이송트레이(11)가 배출된 상태에서 하강작동이 이루어지는 제
