The invention discloses a method for producing easily-oxidized fruits into dried fruits. The dried fruits are produced through a dried fruit production box, the dried fruit production box comprises abox body, and the box body is internally provided with a production chamber and a box door; the production chamber is internally provided with a roasting rack and a roasting device, the top of the production chamber is communicated with a cleaning box and a separation box in sequence, an air tank with protection gas is communicated with the bottom of the production chamber, the input end of the air tank is communicated with the separation box, and the output end of the air tank is communicated with the bottom of the production chamber. The method comprises the steps that the box door is opened, the cut fruits are placed in the roasting device, arranged through layering, in the roasting rack, then the whole dried fruit production box is started, the protection gas is heated by the roastingdevice to form hot protection air flow, the hot protection air flow flows into the roasting rack, the roasting rack is roasted through a three-dimensional mode, finally the hot protection air flow enters the cleaning box from the top of the production chamber and is cleaned by the cleaning box, the cleaned protection gas enters the air tank secondarily and is heated by the roasting device again toform hot protection air flow at last, and circulation is achieved in this way.
